附录

From 1894, a French engineer to a car fitted with the world's first

transmission date, transmission has been car a hundred years of development.

Important for the automotive transmission component of the commitment to

enlarge the engine torque, torsional characteristics of reactive power with the

engine, to achieve the desired power transmission, and thus adapt to various road

conditions to achieve the main devices driving.

The first is the use of manual transmission. Later, for the convenience of

motorists, in the collar between adjacent gear fitted with a synchronizer, the

synchronizer rely on, and we do not need to shift to judge the speed. Manual

transmission is still present in the automotive industry a wide range of

applications, automatic transmission is a trend, but the manual transmission is

great fun, embodied persons.

The traditional gear transmission with the use of different shift achieved the

purpose of twisting, but with the change of gear by foot only hand-off to achieve,

and this is the so-called manual transmission. Easily shift to achieve the abolition

of clutch pedal and manual the AT (AutomaticTransmission) transmission

occurred, it is the main browser using hydraulic Torque traditional mechanical

gearbox with the shift function to achieve. In fact, as early as the 1948

Oldsmobile car GM has already emerged on the automatic transmission is now

taking shape, but then the automatic transmission is only the addition of hydraulic

coupler manual transmission only.

AT used because earlier, so the English name is called "automatic

transmission." However, AT is not the same as in the automatic transmission. As

long as we can to achieve the automatic transmission shift automatic transmission

can be called, it is necessary to achieve this in fact means a lot: In addition to AT,

but also includes other forms of CVT. However, before the overthrow of the name

can not, so let us not think so: automatic transmission (AT) including: hydraulic

transmission (AT), Electronically Controlled Transmission (ECT), non-polar

transmission (CVT).

1908 Ford Model T the first use of a two-speed ratio automatic transmission.

Constructed using multiple sets of gear, and gear into the central and peripheral

gear, the outside is a runner, with the introduction of the central gear of the torque

from the engine is different from camera gear groups so as to be different levels

of speed, including Reverse rotation reversing file. Runner-type automatic

transmission, there is a drawback, that is, when people start to accelerate there is a

feeling of spin the wheels, so drivers will be meng refueling door, but does not

immediately increase the speed again. At present, some manufacturers such as

Nissan and Fiat, have recourse to some electronic device to try to eliminate this

shortcoming, Nissan Primera and the 6-speed transmission Fiat Punto 7-speed

gearbox is the result of this effort. Drivers pulled no need to handle, they can

easily change the speed.

Although the automatic transmission continue to evolve and progress, but

there will always be a drawback, that is, the response speed of action and between

the pedal there will always be a gap, driving in the impression of a lack of

intuition. Appeared in 1969 and the electronic control systems appeared in 1982,

which was to improve digital technology.

With the engine fuel injection and ignition devices continued to be refined,

automatic transmission is also new tricks, such as set up a "campaign-style 'or"

snow road ", such as the manipulation of different ways, some in the instrument

panel has a bearing S letter button, you can become extremely rapid acceleration;

or snowflake patterns are printed on the button on behalf of the snow moving to

avoid slipping in the start. Even worse, a new generation of "adaptable style"

Transmission can also adapt to motorists different habits, the corresponding

reaction, so that drivers will become more user-friendly. the intelligent automatic

transmission, and spread to the vehicle mass, which is a credit to the French. in

1997 with the Renault Clio Peugeot 206 took the lead in the most advanced

computer-controlled technology and is known as "fuzzylogie" the principle that

"fuzzy logic." This car can drive based on the temperament, road conditions,

vehicle load and the surrounding environment and other factors, in the nine kinds

of programs select the most suitable function, the realization of intelligent driving,

in order to give full play to the vehicle performance and reduce fuel consumption

and ensure safety. now that is, continuously variable transmission CVT

(ContinuouslyVariableTransmission) also have been widely used, continuously

variable transmission system in the non-use of gears, to provide smooth and "no

class" conversion ratio of the transmission system at the same time light weight,

small size, the characteristics of small parts, is recognized as the ideal vehicle
