Abstract

The embodiment of the invention provides a differential mechanism and a vehicle. The differential mechanism comprises a shell; the half axle gear is rotatably arranged on the inner wall of the shell; the planetary gear is rotatably arranged on the inner wall of the shell and is meshed with the half axle gear; the corrugated gasket is arranged between the half axle gear and the inner wall of the shell and is used for providing pre-pressure towards the planetary gear for the half axle gear; the technical problems that in the prior art, although the size of the meshing backlash can be reduced to a certain degree through an annular plane gasket, the problem that the backlash causes vehicle starting or gear shifting impact, and consequently the comfort degree of a vehicle becomes poor cannot be effectively solved.

Description

technical field [0001] The invention relates to the technical field of speed regulation, in particular to a differential gear and a vehicle. Background technique [0002] There are two kinds of straight-toothed bevel gears in the existing differential, planetary gears and side shaft gears. The two are meshed with each other, and the meshing side clearance is generally 0.05-0.25mm. The gap is caused by the shock of the vehicle starting or shifting. One of the main factors leading to poor vehicle comfort. [0003] At present, an annular plane gasket is generally used between the side gear and the differential case to reduce the meshing backlash between the planetary gear and the side gear, but the use of the annular plane gasket Although the sheet can reduce the size of the meshing side gap to a certain extent, it cannot effectively solve the technical problem that the gap causes the vehicle to start or shift shock, resulting in poor vehicle comfort.
