What are the characteristics of automobile gears?
Automobile gear is one of the most widely used transmissions in automobiles. It mainly has the following functions:
1. Speed change: By meshing two gears of different sizes, the speed of the gear can be changed. For example, transmission gears can reduce or increase the speed transmitted from the engine to meet the driving needs of the car.
2. Torque conversion: The meshing of two gears of different sizes not only changes the speed of the gears, but also changes the transmitted torque. of torque. For example, the automobile gearbox and the main reducer in the drive axle can change the torque of the car.
3. Direction change: The direction of power of some car engines is perpendicular to the direction of travel of the car, and the direction of power transmission must be changed to drive the car. This device is usually the car's final drive and differential. Gear transmission has the advantages of high transmission efficiency, compact structure, reliable gear transmission operation, long service life and stable transmission ratio. Its transmission efficiency can reach 99%. Among commonly used mechanical transmissions, gear transmission has the highest efficiency
