Anti-skid differential and automobile

Abstract

The invention discloses an anti-skid differential. The anti-skid differential comprises a first output flange, a second output flange, a first half shaft and a second half shaft. The first half shaft is fixed to the first output flange. The second half shaft is fixed to the second output flange. The first half shaft is arranged in a first differential shell in a sleeved mode. The second half shaft is arranged in a second differential shell in a sleeved mode. The first half shaft is sleeved with a first spiral spring. The second half shaft is sleeved with a second spiral spring. The two ends of the first spiral spring act on the first output flange and the first differential shell respectively. The two ends of the second spiral spring act on the second output flange and the second differential shell respectively. The anti-skid differential can transmit a larger torque. Meanwhile, the trafficability, the traction property and the travel safety of an automobile can be improved by the anti-skid differential. The invention further discloses an automobile.

Description

technical field [0001] The invention relates to the technical field of automobile structure design, in particular to an anti-slip differential. The invention also relates to a motor vehicle. Background technique [0002] The differential is an important part of the car drive axle, its main function is to make the left and right drive wheels of the drive axle have the differential speed required by the driving kinematics of the car, and distribute the power to the left and right drive wheels. However, the "differential speed is not bad torsion" of the ordinary differential, that is, the equal torque distribution performance, has seriously affected the passability, traction and driving safety of the car. [0003] Most cars drive on roads with relatively good adhesion conditions, and almost all of them adopt ordinary symmetrical conical planetary gear differentials with simple structure, stable operation, convenient manufacture and good reliability; Or for off-road vehicles o...

Problems solved by technology

[0013] However, the torque that can be tolerated between the friction plates or between the slider and the cam is relatively small, and large torque cannot be transmitted

However, the pre-pressed friction disc bevel gear differential sets the coil spring between the two side gears, resulting in a limited space for the coil spring, resulting in unsatisfactory trafficability, traction and driving safety of the car.
