What is an Automatic Transmission in a Car?
1 Answers
An automotive transmission is a gear system designed to coordinate the engine's rotational speed with the actual driving speed of the wheels, optimizing the engine's performance. During vehicle operation, the transmission creates varying gear ratios between the engine and wheels. Below are further details about automotive transmissions: 1. The transmission alters the gear ratio to expand the range of speed variations, adapting to frequently changing driving conditions while maintaining the engine's operation within favorable conditions (higher power output with lower fuel consumption). 2. It enables the vehicle to reverse direction while maintaining the engine's rotational direction. 3. Utilizing neutral gear, it interrupts power transmission, allowing the engine to start, idle, and facilitating gear shifts or power output. A transmission consists of a gear mechanism and a control mechanism, and can be equipped with a power take-off when necessary.
