Transmission gear is the gear in the transmission box, the main role is to change the speed and torque from the engine, that is, the power of the engine from a stepless speed change to a stepless speed change, in order to facilitate shift. Transmission gears are divided into the following categories according to different types and materials:
1. Manual transmission gear: mainly composed of the driving gear on the shaft, driven gear, sliding gear on the intermediate shaft, etc. The main function is to change the rotation direction of the engine crankshaft and transfer the power of the engine to the driving wheel.
2. Automatic transmission gear: including input shaft gear, output shaft gear, singular gear, even gear, etc., the main role is to change the transmission ratio, transfer the power of the engine to the output shaft of the gearbox, thereby driving the wheels.
3. Transmission gear: mainly used to transmit power, but the transmission ratio is very small, usually between a few to ten. In addition to achieving deceleration and torque increase, it can also act as a separation between the input and output shafts.
4. Reverse gear: used when reversing, it can transfer the power of the car forward or backward to the output shaft to achieve the reverse function.
In short, the transmission gear plays a vital role in the process of car driving, if the failure may lead to the vehicle can not run normally, so it is recommended that the owner regularly check and maintain the gearbox to ensure driving safety.
