What Components Make Up an Automatic Transmission?

[Ariana]

Here is an introduction to the components of an automatic transmission: 1. Common components include the torque converter, planetary gear set, clutches, brakes, oil pump, filter, pipelines, valve body, and speed governor. 2. Based on their functions, these components can be divided into five major parts: the torque converter, gear mechanism, oil supply system, automatic shift control system, and shift operating mechanism. Below is a detailed introduction to the components of an automatic transmission: 1. The torque converter is located at the front end of the automatic transmission and is mounted on the engine's flywheel. Its function is similar to that of the clutch in a manual transmission vehicle. 2. The planetary gear set is one of the most important components of an automatic transmission, mainly consisting of the sun gear (also called the center gear), internal ring gear, planetary carrier, and planetary gears. 3. The shift actuation mechanism is primarily used to change the driving elements in the planetary gear set or restrict the movement of certain elements, altering the direction and ratio of power transmission. It mainly consists of multi-plate clutches, brakes, and one-way overrunning clutches. 4. The brake's function is to hold a specific element in the planetary gear set stationary.
