In
the beginning, the car is used in manual transmission, that is, we often say
that the manual block, that is, you must manually dial the "block" to
change the china transmission gear within the gear meshing position, change the
transmission ratio, so as to achieve speed the goal of. In order to start in the
place, climbing, turning, acceleration and other conditions, so that the car to
obtain different traction and speed, while the engine work in a more favorable
conditions of the environment.
Then
the automatic transmission appears, greatly reducing the driver's fatigue.
There are still a lot of people in the tangled to buy a manual car is good or
automatic car is good, in fact, I think there is nothing tangled. If you are
living in a second-tier cities, often facing the traffic jam situation, I
advise you to start automatically more appropriate, in the traffic jam when
driving the car too tired. But if you live in a convenient city, rarely
encountered congestion, you can start hand block, one is cheap, the second is
fuel-efficient.
The
following are the same as the "
Automatic
transmission can be divided into general automatic transmission, dual-clutch
transmission, CVT continuously variable transmission. In these three
transmissions, I think the tiptronic transmission is the most stable, the
production cost is centered, is a combination of manual speed and automatic
transmission speed of the transmission device, this technology is to improve
the automation of the transmission and Handling, and can be automatically
determined by the computer shift time to return to the hands of the driver,
thereby enhancing the driving of the operation, enrich the driver's experience.
The

The
double-clutch transmission can be divided into dry double-clutch and wet
double-clutch, dry double-clutch manufacturing costs are low, the opposite wet
dual-clutch production costs are relatively high. Dry and wet dual-clutch in
the working principle and the basic structure is no essential difference, the
biggest difference is the friction plate heat treatment is different, dry
double-clutch mainly through air-cooled heat, resulting in poor heat, which led
directly Dry double clutch fault frequently.
The
following are the same as the "
The
beginning of the dual-clutch transmission by the major manufacturers of the
main reason is that it has a rapid shift, fuel-efficient, small power loss
advantages, but after the public DSG burst out of various problems, such as
crystallization, frustration, jitter, power interruption, Is the city traffic
jam, low speed stop and go when the time is particularly evident, the surface
seems to be dry double-clutch heat is not good, in fact, the transmission
control software is not smart enough, especially the city traffic jam, it can
not correctly prejudge you Upshift or downshift, resulting in frequent
problems.
The
following are the same as the "
Although
the dry dual-clutch transmission in the market use, there are many problems,
the owner response is not good, but there are still many manufacturers put into
use (including independent research and development and technology), the main
reason is the light weight, low cost By the major manufacturers like. At
present, civil vehicles, the public's dual-clutch technology and Honda's
8-speed dual-clutch technology is also better. Xiaobian can only say this one,
equipped with dual-clutch transmission of the car carefully selected to
determine whether it is good or bad way to test drive.
The
following are the same as the "
CVT
CVT is common in Japanese cars, and now their own brands have also started to
use, its production costs higher than the manual transmission. Unlike
conventional transmissiones, CVT does not use china transmission gear for
variable speed, but uses a pulley combination to achieve a change in chinatransmission gear ratio. The advantage is smooth shift, no frustration sense,
comfort, fuel consumption is relatively low. The disadvantage is the lack of
driving pleasure, post-maintenance costs are higher.
