What is the function of an automatic transmission?
1 Answers
Automatic transmission serves the following purposes: 1. Altering the transmission ratio to expand the range of torque and speed variations in the driving wheels, adapting to frequently changing driving conditions while keeping the engine operating under favorable conditions; 2. Enabling the vehicle to reverse while maintaining the same engine rotation direction; 3. Utilizing neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifts or power output. An automatic transmission is a gear-shifting device that automatically adjusts based on vehicle speed and engine RPM, as opposed to a manual transmission. Common types of automotive automatic transmissions include: Hydraulic Automatic Transmission (AT), Continuously Variable Transmission (CVT), Automated Manual Transmission (AMT), and Dual-Clutch Transmission (DCT).
