Small SUV is not recommended to install side pedals

SUV models are welcomed by most citizens. Many people buy a car, the sales consultant in addition to highlight the highlights of the models, but also recommend some car decoration supplies, side step is one of them. Buy a small SUV, need to install china side step?

For small SUV should not be installed china side step problems, professionals, for the body of the higher SUV models, the installation side step can facilitate passengers on and off, but note that too wide side step, easy to let The passengers tripped over when they got on and off.

Professionals also said that most of the SUV are now using the car chassis design, installation side pedal is more play a decorative role, from the practical point of view, it is recommended not to install.

How to maintain the hydraulic power steering pump?

In general, in the normal use and maintenance, for the hydraulic china power steering pump, the need to pay attention to the following points:

1. Hydraulic power steering pump in the use of attention to select the correct type of help oil, otherwise it will affect the china power steering pump efficiency and service life.

2. Always check the use of auxiliary oil, the use of auxiliary oil must be kept clean. Regularly replace the booster oil, the owner of the self-refueling oil must be equipped with a filter device.

3. If the car stops for a long time, do not work at full capacity immediately after restarting, at least 10 minutes of no-load operation, until the oil and other oil are in normal working condition.

4. When handling the steering of the car, observe whether the power steering system is operating properly, whether the impact or noise, help the oil circuit with or without leakage phenomenon, in order to detect and troubleshoot.

Fatigue Performance Analysis of Automobile Engine Crankshaft

Crankshaft is an important part of the car engine, both in the car crankshaft R & D or actual production stage, need to test the fatigue performance of the car crankshaft. In the actual operation of the car engine, the crankshaft to bear the form of the load for the bending and torsional load, so the actual case shows that the main form of failure of the car crankshaft fatigue damage. In addition, if the engine crankshaft output power is large, the greater the torque generated, will produce a certain degree of torsional fatigue damage. Early automotive engine crankshaft used by the material for the 40Cr and 42CrMo and other carbon quenched and tempered steel. However, since the late 1990s, a large number of automotive crankshaft began to widely use non-quenched and tempered steel, especially for heavy-duty engine crankshaft production, the materials used mainly include 48MnV and C38N2, these two materials and medium carbon Compared with the quenched and tempered steel, in the case of ensuring the same strength, a lot of conditioning process is omitted. In recent years, the use of ductile iron production of china crankshaft has better mechanical processing performance and bending fatigue strength, especially in the use of heavy-duty engine to show a good application prospects.

Automotive crankshaft in the design, the choice of raw materials, forging, machining and heat treatment and surface strengthening of all aspects, if any one part of the mistakes will cause the china crankshaft failure. A company combined with the actual bearing production case, introduced and analyzed the car engine crankshaft common failure form and internal reasons.

The factors that affect the fatigue strength of the crankshaft of the vehicle mainly include the stress concentration, the size, the surface condition and the environment medium at the journal. In these factors, stress concentration and size and surface state are most important. The factors that affect the stress distribution of the crankshaft mainly include the design shape of the crankshaft and the basic properties of the material. The bending fatigue strength of the crankshaft can be improved by changing the kind and size of the material, but this will greatly increase the manufacturing cost of the material. In the actual application process, the surface strengthening process is usually used to improve the fatigue strength of china crankshaft. Under the effect of variable load, the maximum stress should appear in a range near the rounded corners of the crankshaft due to the abrupt change in the shape of the crankshaft journal Inside. Research indicates:

(1) Fatigue test of automobile crankshaft The fatigue limit of crank moment is 96.7MPa, the crankshaft stress concentration coefficient is 6.72, and the fatigue test process is in the middle of crankshaft journal. The safety factor at 99% was 1.31.

(2) SEM microstructure analysis of the microstructure and crack fracture of the 40Cr crankshaft journal shows that the microstructure after 40Cr quenching and tempering is tempered sorbite + ferrite + few bainite, conforms to the relevant standard The Fracture analysis shows that the 40Cr crankshaft fracture is a typical dimple and step mixed fracture, and no obvious inclusions.

(3) From the chemical composition and tensile properties of the material and the hardened layer of the journal surface, it can be seen that the reason of the fatigue failure of the crankshaft can exclude the influence of the above factors.

(4) crankshaft drilling hole in the journal internal wall caused by stress concentration, more prone to defects; crankshaft journal under the action of alternating stress is prone to fatigue cracks and expansion, resulting in early fracture of the crankshaft.

Electric commutator market space

Since the invention of the car for more than 100 years, the development of the steering gear has undergone a gradual development from the initial mechanical steering gear to the hydraulic china commutator, electric control hydraulic commutator, electric power steering process. There are industry experts, the future may be to the steering system and active front wheel steering system development.

It is understood that, compared with the hydraulic power steering, electric china commutator both energy saving, but also to meet people's increasingly demanding handling of the car, and its product prices (mainly electronic components) will be with the production Rising trend is very suitable for the general type of car on the assembly. So the electric commutator market development is huge, is the focus of the current automotive steering gear industry.

Experts, due to lack of technology, China has no local suppliers to mass production of electric steering system, local brands are rarely installed electric steering system. The chief representative of a professional advisory body in China predicts that the electric steering system will use a motor rather than a hydraulic press to turn the wheel, its lighter weight and fuel economy is higher, the next five years, the annual growth rate of electric steering system sales up to 30 %.

Child safety seat three kinds of fixed way knowledge popularization

Children's safety seats are commonly used in ISOFIX, LATCH and three-point china seat cover belts in three ways to install, to understand the difference between them and the pros and cons, according to their own car interface and their own situation to buy safety seats are very Big help.

1, three-point seat belt fixed

Seat belt connection, refers to the use of the car comes with 3-point china seat cover belt safety seat fixed in the car seat on a connection. This approach is currently the most common. At the same time, because this connection does not require a safety seat comes with a special interface, all of its versatility is strong, no matter what car, can be installed, and the price of this seat is relatively low, so The choice of most riders.

When using the china seat cover belt connection, pay attention to the instructions in strict accordance with the instructions in the installation, use a period of time after the need to check whether there is loose to prevent the safety seat can not protect the baby's role.

ISOFIX (International Standards Organization FIX) Child Safety Seat Fixing System. ISOFIX is a new standard for the placement of child seats in cars. Its role is to make the child seat installation becomes fast and simple, rigid connection, will be more secure. With ISOFIX child seat can be easily fixed to the car's ISOFIX interface, increase security; In addition, with ISOFIX interface security seats, but also compatible with LATCH interface with the car. So, ISOFIX is the most versatile dedicated interface.

Because ISOFIX is hard-wired, it is easy to install and avoids many installation errors that can cause the seat to fail.

LATCH is the abbreviation of "Lower Anchors and Tethers for CHildren", which belongs to the American standard, generally appear in the US Department of safety seat models and the US Department of cars. It is the European standard ISOFIX fixed way the biggest difference is that the connection is not a hard link but at the same time hook way connection, and fixed point more than ISOFIX a total of three.

ISOFIX and LATCH are fixed in two ways, LATCH is compatible with ISOFIX, that is, there are LATCH interface can also be installed ISOFIX interface seat, but only ISOFIX interface can not use the LATCH interface child seat (because Missing a fixed point)!
