Springback gasket differential mechanism on-drive axle assembly

Abstract

The invention provides a springback gasket differential mechanism on-drive axle assembly. The springback gasket differential mechanism on-drive axle assembly comprises a left differential mechanism shell, a right differential mechanism shell, a half axle gear, a first half axle gear and a planetary gear cross axle, wherein spherical cavities are formed in the left differential mechanism shell and the right differential mechanism shell, and output holes in communication with the spherical cavities are formed in the two ends of the left differential mechanism shell and the two ends of the right differential mechanism shell respectively; the half axle gear and the planetary gear are positioned in the spherical cavities and are correspondingly meshed; the planetary gear is in key connection with the four ends of the planetary gear cross shaft which is fixedly connected to the interior between the left differential mechanism shell and the right differential mechanism shell. A half axle gear gasket and a first half axle gear springback gasket are both located on a half axle gear step, the planetary gear springback gasket and the first planetary gear springback gasket are both located in a gap between the planetary gear and the left differential mechanism shell and a gap between the planetary gear and the right differential mechanism shell; and compared with the prior art, the springback gasket differential mechanism on-drive axle assembly has the advantages that noises generated in the automobile running process can be effectively reduced.

Description

Technical field [0001] The present invention belongs to the technical field of automobile driving bridges, in particular, to a rebound spacer differential in the drive bridge assembly. Background technique [0002] The car differential can drive the left, right (or before, and then) drive wheels to rotate at different speeds. It is mainly composed of left and right half-axis gears, two planetary gears and differential housings. The effect is when the car turns or travels on a non-flat surface, so that the left and right wheels are rolled by different speeds, that is, the driving wheels on both sides are purely rolled, and the differential is to adjust the rotation speed difference of the left and right wheels. [0003] The current differential is widely used in the driving bridge assembly. [0004] However, existing differentials also exist in the driving bridge assembly, often because of the complex road conditions and poor differential total lubrication, resulting in various fa...

Problems solved by technology

[0004] However, the existing differential still exists in the drive axle assembly. During the normal driving process of the vehicle, it is often due to complex road conditions and poor lubrication of the differential assembly, which leads to various failure modes of the differential assembly and breaks down. Especially when turning at high speed, due to the meshing problem, the torque distribution is unreasonable, and abnormal noises are generated during driving, which seriously affects the psychological state of the drivers and passengers, leads to psychological disorders of the drivers, and easily causes unsafe driving problems.
