The automatic transmission?is a critical component that?transmits engine power to the wheels.?The conventional speed shifting systems installed on most cars have extremely complex, precision structures.
What is an automatic transmission?
An automatic transmission (AT) is installed at a point between the engine's rotation and the point where it is transmitted to the wheels.?An AT automatically changes gear depending on the car's running condition, and transmits rotation from the engine to the wheels.?An AT provides functions that the engine alone cannot perform, such as adding power on slopes, adjusting rotation speed as required during running, decoupling power when stopped, and applying the required opposite rotation when in reverse.
Types of ATs
ATs can be categorized into two types: those installed vertically with respect to the automobile and those installed horizontally. Although the layout of the external and internal components differs depending on the type of engine drive method, the functions basically work in the same way.
