The role of the gearbox

Change the transmission ratio to meet the traction requirements of different driving conditions, so that the engine can work under favorable working conditions as much as possible to meet possible driving speed requirements. Change the driving speed of the car and the torque on the driving wheels of the car within a wide range. Due to the different driving conditions of the car, the driving speed and driving torque of the car are required to change within a wide range.

For example, the vehicle speed on the highway should be able to reach 100km/h, while in urban areas, the vehicle speed is often around 50km/h. When an empty vehicle is driving on a straight road, the driving resistance is very small. , then when going uphill with a full load, the driving resistance will be very large, and the characteristic of the automobile engine is that the speed change range is small, and the torque change range cannot meet the needs of actual road conditions.
