What are the names of the parts inside the transmission?
1 Answers
Transmission parts are named as follows: 1. Torque converter: The torque converter is mounted on the engine flywheel. Its function is to transmit engine power to the planetary gear transmission mechanism and provide a certain torque conversion capability. 2. Planetary gear transmission mechanism: The planetary gear transmission mechanism consists of two parts: the planetary gear set and the shift actuation mechanism. The planetary gear set consists of 2-3 rows of planetary gears to achieve 2-5 gear ratios; the shift actuation mechanism enables the change of gear ratios, i.e., automatic shifting. 3. Hydraulic control system: The main task of the hydraulic control system is to provide the required oil pressure to various systems of the automatic transmission based on signals such as engine load (throttle opening) and vehicle speed (speed sensor). It also switches hydraulic channels according to the gearshift lever position and driving conditions to control the torque converter and gear transmission system, as well as the operation of the lock-up clutch in the torque converter. 4. Electronic control system: In the electronic control system, sensors collect various signals, such as throttle position, vehicle speed, coolant temperature, etc., and convert them into electrical signals sent to the electronic control unit (ECU). The ECU processes the data and compares it with preset shift patterns, then sends commands to the solenoid valves to determine the correct shift timing and gear position.
