The automobile gear is an important part of the automobile transmission system, including the driving gear, the driven gear and the shaft between them.

The drive gear is usually connected to the engine to transfer the power of the engine to the gearbox. The driven gear is connected with the wheel in order to achieve power transmission and drive the vehicle forward during the driving process.

Specifically, automotive gears may include gears in a gearbox, such as input gears, output gears, and reverse gears. The input gear is connected to the engine, the output gear is connected to the wheel, and the reverse gear is used to drive the car into reverse. Other common automotive gears include the main reduction gear within the main reduction gear, which adjusts the power transmission speed by changing the transmission ratio to adapt to the needs of different speeds and driving conditions.

In short, the car gear plays a crucial role in the driving process of the car, providing the vehicle with the required driving force and speed to ensure safe driving.
