Introduction, classification and structure of constant cv joint



The effect of cv joint is to connect the shafts with different angles between the shafts and to change the position of the two axes and to transmit the power at the same angular velocity. It can overcome the existence of the ordinary cross shaft china cv joint Speed problem, especially suitable for the use of steering axle.
Steering drive axle, the front wheel is both the drive wheel, but also the steering wheel, steering deflection angle is great, up to 40 ° or more, then you can not use the traditional, the deflection angle of the ordinary china cv joint. Ordinary cv joint in the deflection angle is large, the speed and torque will be a great fluctuation, the car engine power is difficult to transfer to the wheel smoothly and reliably, but also cause the car vibration, shock and noise. Therefore, we must use the deflection angle, power transmission smooth, angular velocity uniform uniform velocity joints to meet the requirements.

Classification and structure:
Circular Rivet - type Ball - type Universal Joint
Straight groove raceway type ball - type universal joint
Fixed ball cage universal joint (RF section)
Telescopic ball cage universal joint (VL section)

General Situation of China 's Auto Parts Export Trade in 2016

Data show that in 2016 the cumulative export volume of China's auto parts 64.573 billion US dollars, the cumulative decline of 2.81%, accounting for 84.97% of the amount of auto products exports, which can be seen in the export of auto parts in the entire car exports The degree is still great.

2016 China's auto parts export category, the top three driving systems, automotive electronics and body and accessories, respectively, exports 19.082 billion US dollars, 10.373 billion US dollars, 9.272 billion US dollars. In the driving system, the tire exports amounted to 11.456 billion US dollars, accounting for 60.04% of travel system exports, accounting for 17.74% of total auto partsmanufacturers exports, is still a component of the export force. But at the same time due to foreign trade friction in recent years, the adverse effects of tire exports, tire exports showed a significant decline in the trend.

In 2016, China's auto parts exports the top 10 destination countries for the United States, Japan, Korea, Germany, Mexico, Britain, the Russian Federation, Canada, Thailand and India. The amount of exports to these 10 countries was US $ 39,304 million, accounting for 60.87% of the total auto parts manufacturers exports. The data show that China's auto parts exports are dominated by developed countries and emerging countries.

China's auto parts exports in 2017 will face severe, downward pressure on the situation. China's auto products in the international market, "cost-effective" advantage, although there will be no longer obvious; it will enter a major adjustment period, which the Chinese auto industry is also a major strategic opportunity period. Placed in front of auto partsmanufacturers exports in the only way, is to change the growth mode, from simple product exports to technology, capital output changes, speed up product structure adjustment and industrial transformation and upgrading.

The working principle of gas spring

Gas spring is a type of spring that, unlike a typical metal spring, uses a compressed gas, contained in a cylinder and compressed by a piston, to exert a force.

Common applications include automobiles where they are incorporated into the design of struts that support the weight of hatchback doors while they are open.

The elastic coefficient of the china gas spring has a non-linear characteristic. That is, its elastic coefficient is variable to adjust. In addition, such springs are less prone to resonance effect.

According to the general gas to follow the law of Beaire: that is, under a certain temperature, the pressure of the gas and the volume is inversely proportional to the relationship; simply, that is, when the gas volume is compressed to half, the internal gas pressure (Stretch) will be doubled.

With this feature, when the load of the heavy load is carried on the china gas spring, the weight of the compressed gas will be reduced to the upward support stretch. In normal times, the spring is set to a softer elasticity coefficient; and when more heavy loads are carried, the compressed gas can also provide a greater upward support force and is less susceptible to any resilience. Moreover, the gas spring than the traditional metal spring, more able to absorb many small rebound. It can make the passengers feel a more comfortable ride sense; fragile goods are also less likely to be damaged due to epicenter pavement.

There is also an air pressure suspension system that can dynamically adjust the amount of air in the china gas spring: the amount of air inside its spring can be dynamically adjusted due to demand. But because of its need to consider the amount of air to adjust the additional device and adjust the height of the vehicle changes, so the design of such a suspension system than the general design of many complex.

You have to know the auto lights common sense

The driver is safe at night, it is inseparable from it, it is an essential part of the car, it can improve the safety of driving the driver, it is known as the "car eyes" of the lights, the role of lights , The driver should pay attention to the maintenance of lights.

Always check whether the lamp is working properly

Some battery car drivers like to always check their own lights to see if it is working properly? For car drivers, they also have to check their car lights. It is recommended to detect the direction of the headlamps is not offset, the brightness of the light is not enough.

Regular replacement of china car bulb

Are your car's bulb changed regularly? Some people think that the use of light bulbs for a long time all right, in fact, this is the wrong idea. Light bulbs used for a long time will darken, will affect the driver's line of sight, driving at night is very dangerous. Therefore, once found the light bulb dimmed, or the lights of the two china car bulb brightness is not the same, to replace the early to ensure traffic safety.

Always clean the shade

Car used for a long time, after rainy days, the lights will be covered with shades of gray and dirt, which is a kind of headlights damage. It is recommended to always clean the shade.

An analysis of the gap between China's automobile fasteners and foreign countries

As we all know, China and other countries as foreign automotive fasteners fasteners, but do not know where the gap, we can only understand it improved network hardware to star in china auto fastener, and the foreign automobile fastener gap is mainly in the following points.

(1) there is a gap in the concept. The guiding ideology of the world's best automobile fastener supplier in the operation and management of the design is to provide for the host plant, production, sales, service, logistics and other full support, to solve problems encountered in the manufacture of china auto fastener. For example, how to design your engine between the cylinder block and cylinder head need to connect, how much strength, told the fastener supplier, they will do the design, to solve the problem. Today's modern industrial assembly line, whether it is very advanced, or general, the workload of 70% or in the bolt, nut. It is very important for the OEMs to provide a full range of support to the OEMs to solve the fastening problem.

(2) there is a gap in the development mode of enterprises. In 2010, the famous German wvrth group's global sales of $11 billion 400 million, their production scale and specialization typical, provide fasteners service for the global more than and 40 countries and regions of the main automobile factory, China automotive fasteners scale not up, specialization is not very in place.

(3) there is a big gap between the international advanced level of material, equipment, logistics and other related resources. Now some of the world's leading automotive fasteners manufacturing enterprises, have their own special materials, special technology. Special materials are based on the composition and requirements of the product, combined with the joint development of steel, such as the Kobe steel plant in Japan for the engine connecting rod bolts of specialized smelting SCM435 steel. In the aspect of equipment, it is necessary for a lot of automobile fastener enterprises to have a lot of special equipment, and to cooperate with a large number of related equipment.


(4) lack of common technology platform for china auto fastener. China's automotive fasteners R & D expenses accounted for the total lack of automobile fastener sales proportion is low, lack of means of development, construction equipment and facilities investment pressure; automotive fasteners R & D personnel quantity is less, the loss of key technology developers are more serious. Compared with foreign counterparts, the overall structure is irrational, lack of professional personnel and lack of research and development experience. The lack of automotive fasteners common technology platform, the main key automotive engine parts fastening technology research and development platform, the key technology of engine fasteners, automotive fasteners public laboratory materials research platform; but also related to the establishment of automobile fastener industry information resources sharing platform, science and technology information service platform for automotive fasteners, automotive fasteners personnel training platform. Gasgoo can recommend you the best quality china auto fastener.

How did window failure fail?

Glass lifter is the car doors and windows of the lifting device, the main sub-electric glass lifts and manual glass lift two categories. Now many car doors and china car window of the lift (off and open) has abandoned the shaking of the manual lift mode, generally use the button-type electric lift mode, that is, the use of electric glass lifter.

Structure of electric glass lifter:

Arm glass lifter because of its simple structure, easy processing, low cost, so the use of vehicles in China is more common. Toyota to see Roller and other models are used in such a structure of the lifter, so we focus on the introduction.

Single-arm glass lifter:

The single-arm glass lifter has only one lifting arm, the structure is the most simple, but because of the relative position between the lifting arm and the glass center of mass changes, the glass lift will produce tilt, stuck, the structure is only applicable to both sides of the glass For the parallel straight edge of the situation.

Double-arm glass lifter:

Double-arm glass lifter is characterized by two lifting arm, according to the arrangement of the arms are divided into parallel arm lift and cross arm lift. Compared with the single-arm glass lifter, double-arm glass lifter itself can ensure that the glass parallel lift, lifting force is relatively large. Which cross-arm glass lifter support width is larger, relatively stable movement, is widely used.

Parallel arm glass lifter structure is relatively simple and compact, but because the support width is relatively small, the work load is large, so stable stability is not as cross-arm glass lift

electric glass lifter electrical parts:


When the street ignition switch, the door and china car window relay electric shock, the electric door circuit and power connected to the combination switch or sub-switch with the "up" bit connected to the current flow through the doors and windows motor, motor rotation driven hoist, the doors and windows to rise; The combination switch or sub-switch with the "next" bit connected to flow through the doors and windows of the motor to change the direction of the direction of rotation of the motor and thus change, lifts driven doors and windows decline. When the doors and chinacar window rise or fall to the end, the circuit breaker is switched off for a period of time and then returned to the on state. Gasgoo can recommend you  the best quality car window.

Wiper motor principle and use you will? Let's learn together

Role is the role of the china wiper motor when driving in the rain and snow, clear windshield rain or snow, make sure that the driver has a good line of sight.

The basic structure of the automobile electric wiper water device, according to the different dynamics can be divided into the vacuum pneumatic and electric three. Because the electric wiper has high power, reliable operation, easy to control, and has not influence the working condition of the engine, which has been widely used.


So, here we only introduce the structure and working principle of china wiper motor. The electric wiper is driven by a miniature DC motor, through the linkage mechanism, the outer surface of the windshield wiper blade swing back and forth, to remove the windshield of the rain, snow or dust. The driving part is composed of a miniature DC motor.

You should know about the history of universal joints

Universal joint (universal coupling, U-joint, Cardan joint, Spicer or Hardy Spicer joint, or Hooke's joint) is a joint or coupling in a rigid rod that allows the rod to "bend" in any direction, and is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft.

The main concept of the china universal joint is based on the design of gimbals, which have been in use since antiquity. One anticipation of the universal joint was its use by the ancient Greeks on ballistae.[citation needed] In Europe the universal joint is often called the Cardano joint or Cardan shaft, after the Italian mathematician Gerolamo Cardano; however, in his writings, he mentioned only gimbal mountings, not universal joints.

The mechanism was later described in Technica curiosa sive mirabilia artis (1664) by Gaspar Schott, who mistakenly claimed that it was a constant-velocity joint. Shortly afterwards, between 1667 and 1675, Robert Hooke analysed the joint and found that its speed of rotation was nonuniform, but that this property could be used to track the motion of the shadow on the face of a sundial. In fact, the component of the equation of time which accounts for the tilt of the equatorial plane relative to the ecliptic is entirely analogous to the mathematical description of the china universal joint. The first recorded use of the term universal joint for this device was by Hooke in 1676, in his book Helioscopes. He published a description in 1678, resulting in the use of the term Hooke's joint in the English-speaking world. In 1683, Hooke proposed a solution to the nonuniform rotary speed of the universal joint: a pair of Hooke's joints 90° out of phase at either end of an intermediate shaft, an arrangement that is now known as a type of constant-velocity joint. Christopher Polhem of Sweden later re-invented the universal joint, giving rise to the name Polhemsknut in Swedish.


In 1841, the English scientist Robert Willis analyzed the motion of the universal joint.By 1845, the French engineer and mathematician Jean-Victor Poncelet had analyzed the movement of the china universal joint using spherical trigonometry.

What are the ways to open the car doors?

When you can not drive the car, it is too embarrassing. Different models have different chinaauto handle open method, of course, most models still no problem.

However, there are sports car on the use of hidden door handle, the common hidden china auto handle are appearing in the back door, such as hidden in the C column, on behalf of the type of wide wisdom / XRV, Chery A3 and so on.

What is Iridium, Platinum, Nickel Alloy Spark Plug?

Application of the china spark plug electrode noble metals are iridium, platinum, nickel three, they have what characteristics?

Iridium is a high hardness and brittle, silver-white platinum group transition metal, high temperature can be pressed into thin slices or drawing. Iridium is the second highest density element (inferior to osmium), iridium is the most corrosion-resistant and wear-resistant material even at the high temperature of 2000 . Iridium in the alloy is more resistant to high temperatures and corrosion, such as china spark plug electrode is the use of iridium is the use of this feature.

Platinum is a transition metal, density, scalability, color silver, metallic luster, hardness 4-4.5, the relative density of 21.45. The high melting point of 1773 . As the melting point of platinum than iridium (2410 ± 40 ) is low, so the performance is inferior, but compared to the most common nickel alloy is still much stronger. Rich ductility, can be pulled into a very fine platinum wire, rolled into a very thin platinum foil. Chemical properties of a very stable, insoluble in strong acid and alkali, dense metal platinum at any temperature of the air are not oxidized.

Nickel chemical symbol for the atomic number of 28, a magnetic, silver-white transition metal, the melting point of 1453 ° C. In the nature of nickel silicate ore or sulfur, arsenic, nickel compounds exist. Of tough, magnetic and good plasticity in the air is not oxidized, soluble in nitric acid. The general center of the nickel alloy spark plugs will be relatively thick, so after a period of time in the use of ignition stability will be worse.


These three kinds of metal as the central electrode of the chinaspark plug are called iridium spark plug, platinum spark plug, nickel-copper alloy spark plug. Gasgoo has those all. 

Innovation and enhance the core technology of electric vehicles in China

Assembly car audio: speakers and more does not mean that the sound is good

Assembly of car audio in the process of the following points should pay special attention to: First, the treble to try to close to the tenor, if left too far, there will be serious off-frequency phenomenon. If coaxial china car speaker, which is placed in the treble treble, can effectively reduce the frequency, phase is easy to grasp. Secondly, if the car space is small, remember not to use the three-way design, due to frequency handover error affecting the sound field positioning. Third, the directivity of the treble position absolutely determines the location and depth of the sound field, to test more different locations. Fourth, the middle part of the high-quality unit to select the low frequency to 80hz to create a dynamic performance to the front of the sound field. Fifth, the use of machine, measurement and measurement is correct. In addition, the door should be coupled with shock-absorbing plate, to prevent low-frequency noise caused by the sound field.

After meeting the above basic requirements, the high, middle and woofer directions are all well matched, and then the instrument can be tuned to obtain high-quality sound in the car.

Good sound design, installed, of course, must also take care of the overall beauty of the car. In this regard, popular in recent years is the fiber decoration. High plasticity of the fiber, according to different china car speaker and other location design, make a different shape of the curvature, greatly improving the aesthetic appearance of the car. Making the car not only has a good sound, but also for car audio assembly to provide greater play space.


The economic and practical car audio players may wish to step by step purchase equipment, this method can not suddenly purse bleeding, and can be assembled to good equipment. However, this method, the first player to plan an investment plan, list the entire purchase list, according to the urgency of the arrangements have purchased components. So gradually purchased, and finally can be purchased for the car to good equipment, get the highest sound enjoy. Gasgoo has a lot of matching original speakers such as Ford,BMW and Benz ect.

How to buy power inverter?

What is a power inverter?

Power inverter on the car is about 12V (24V diesel vehicles) DC 220V AC for home conversion, for small household electrical appliances in the car using electronic equipment. china power inverter is divided into two kinds, one is connected cigarette lighter, and the other need to install their own lines. It is recommended to select the cigarette lighter-type power inverter, so no need to change the original car line, simple and convenient.

How to choose for your inverter?

1. Power selection
For ordinary family car, buy a maximum power of 200W in the following inverter is completely sufficient. The vast majority of household car 12V power supply used by the insurance are less than equal to 20A, the maximum also allows about 230W of electrical appliances, and some older models, insurance, the maximum allowable current of only 10A, so buy china powerinverter can not Only coveted high-power, select the appropriate power of the optimal.
For some outdoor workers, it is the need to use high-power electrical appliances crowd, you can choose to directly connect the battery inverter. This inverter can be used for 500W or even higher electrical use, can drive a small motor and some frequently used 1000W photo soft box.

2. Output interface
Power selected, depends on the inverter's own output interface. At present, a lot of electrical appliances used in the three-pin plug, which requires a three-hole inverter interface, in addition, USB interface is also useful, so the best choice of three interfaces have the inverter.

3. Output waveform
According to the different output current waveform, vehicle inverter is divided into pure sine wave inverter and modified sine wave inverter. Among them, the pure sine wave inverter power supply stability, the common electrical appliances can basically be a good drive, but the higher prices, some high-end inverter output 220V AC power quality even higher than the daily electricity. The modified sine wave is actually closer to the square wave, the output current quality is poor, but in most cases stability can be guaranteed for ordinary consumers to buy.

4. Protection function

When you buy a chinapower inverter, be sure to confirm whether it has over-voltage shutdown, undervoltage shutdown, over temperature protection, overcurrent protection and short circuit protection functions, these functions not only provide protection to the inverter itself , More importantly, to avoid damage to electrical equipment. Come to Gasgoo to buy the most suitable for your power inverter.

Vigorously shut the door when it will hurt the car?

We take a taxi, or take the car, it may often encounter such a group of friends, on and off the china auto door when the force with the big, "biang" so soon, I feel the car should be shaking. This injury in the end does not hurt the car?

You know the upper part of the iron gate is glass, hollow, and only outside a frame and the following piece of iron, it is the body of the door.

In this chinaauto door below the glass, which put a lot of small metal inside a lot of things, what window lifts, door locks, speakers, crash beam, a little better there are waterproof car, soundproof layer, the more high-end car Of course, the more things inside.

You close the heavy, off the powerful, most likely inside the component, it will occur a slight displacement, engage in a bad there may be problems.


So I suggest that friends, the effort also do not have to deliberately to control, different cars want to close the china auto door lock strength, the requirements are different. If your door is bad, you can come to Gasgoo to buy

Do not blindly trust car GPS

It is understood that the current china car GPS system focused on the outstanding performance in three major areas. Among them, GPS quality problems mainly in the positioning accuracy is low, poor sensitivity, the signal is often lost, can not navigate. At the same time, the brand china carGPS loaded with different operating software, often a variety of problems. Some cottage goods, navigation software, poor performance, often crash, people bored annoying. In addition, some navigation software lack of path reset function, resulting in deviation from the scheduled route, the navigation system will only repeat the " Please turn around ", and will not be reset path, and eventually lead to panic.


Of course, the most prominent china car GPS map problem. Many owners use the navigation device encountered because the old map can not reach the destination of the situation, but also often an important traffic signs are not updated, resulting in illegal driving or detour drivers take the wrong way. Once the updated version of the map, regardless of 4S shop or professional navigator stores, the basic will not take the initiative to inform the owner. Do not blindly trust car GPSbut can trust Gasgoo recommend for you.

Mistakes in the Use of Heater in Winter

Cold weather in winter, many people used to enter the car immediately on the heater and chinaauto fan to open, wait for an instant to warm up, but the heater system can not only open the switch off as simple as there are many misunderstanding is the owner does not know, to understand these Knowledge, can really use the car warm air properly.

1. Car just started to open heater

  Winter engine has just started, the temperature of the water tank is still very low, then open the heater, not only can not quickly raise the car temperature, but increased the burden on the engine, delayed the normal increase in engine temperature.

  It is recommended to start the engine warm-up, and other engine temperature pointer to the middle position, and then open the heater, while the air circulation is set to external circulation, so that the car's cold air excluded vehicles, waiting for 3-5 minutes, the air circulation Set to the inner loop.

2. Press the AC key to turn on the warm air

  Press the AC button is to start the compressor, popular that is to open the air-conditioning, and heating is not required to press the AC key. Because the heating is the original distribution of heat through the tank to transfer part of the car into the open air, so need to offset part of the engine power, heating is not affected power.


3. Open the heater will increase fuel consumption

Many owners worry about fuel costs as much as possible to avoid less open heater, it is not. The car heater is the cooling system of the engine in the process of cooling the engine is a small china auto fan to heat into the car; in the heating is turned off, the china autofan stops, while the heat sealing off, the heat will be scattered into the atmosphere. Therefore, the car heating is waste recycling, will not consume oil. Gasgoo helps you to find the right applicable method and china auto fan.

Wiring harness industry needs to occupy the market core competitiveness

Automotive wiring harness is a key component of automotive electrical system is an important part of automotive circuits, automotive electrical systems in the main role is to convey the energy signal transmission. Can be said that no china wiring harness, there is no car electrical system, wiring harness is an important vehicle electrical system carrier.

Today, information technology, the rapid development of electronic, has spread to the traditional automotive field. The china wiring harness is widely used in all kinds of electrical equipment because of its convenient installation. From the traditional automobile to the intelligent automobile and new energy automobile, the electrification degree of the automobile is more and more high.


It is reported that the traditional diesel locomotives with more than 2km of the wire, mainly in the top lights, door lights, turn signals and a variety of car lights, etc., and the main power line like a ground wire, the engine hub is the main application of automotive wiring harness field. In the traditional diesel locomotives on the thread on the number of up to 2000, and in high-end cars, there are more than 4000 contacts. In the popular electric vehicle, it is more than a traditional diesel locomotive an electric drive system, so compared with ordinary cars also need more high-voltage china wiring harness to connect the various units in the circuit.

Do you know the importance of parking brake?



In cars, the parking brake, also called china hand brake, emergency brake, or e-brake, is a latching brake usually used to keep the vehicle stationary. It is sometimes also used to prevent a vehicle from rolling when the operator needs both feet to operate the clutch and throttle pedals. Automobile hand brakes usually consist of a cable directly connected to the brake mechanism on one end and to a lever or pedal at the driver's position. The mechanism is often a hand-operated lever (hence the hand brake name), on the floor on either side of the driver, or a pull handle located below and near the steering wheel column, or a (foot-operated) pedal located far apart from the other pedals.

The most common use for a parking brake is to keep the vehicle motionless when it is parked. Parking brakes have a ratchet locking mechanism that will keep them engaged until a release button is pressed. On vehicles with automatic transmissions, this is usually used in concert with a parking pawl in the transmission.

Chinahand brake are also used to assist in hill starts on vehicles with manual transmissions. Use of the handbrake frees both feet for use on the accelerator and clutch pedals, allowing the car to move off without rolling back at all.

China hand brake are never used to slow the vehicle when it is in motion, as doing so generally locks only the back wheels and sends the car into a handbrake turn. Handbrake turns are often used in street racing to initiate drifting, but such a maneuver is often seen as an error among regular road users, and is dangerous in many situations. Car chassis repairs, including the related vulnerability of the three systems under the chassis system, including brake pads, brake shoes, steering booster, clutch, steering gear components. Here you can find high-quality chassis components to meet your needs.
