Description

Differential mechanism assembly with planetary gear gasket anti-rotation structure

Technical Field

The utility model relates to the technical field of automobile transmission systems, in particular to a differential mechanism assembly with a planetary wheel gasket anti-rotation structure.

Background

A planetary wheel gasket is arranged between a planetary wheel and a differential gear shell in the existing automobile differential mechanism assembly, but under the severe slip working condition of a vehicle, the planetary wheel rotates and drives the planetary wheel gasket and the differential gear shell to rotate relatively, so that the differential gear shell is worn out, the differential gear shell is worn out excessively finally, the meshing gap between a differential gear and the planetary wheel is enlarged, the gear is easy to cause gear tooth due to meshing dislocation, and finally the whole differential mechanism assembly is scrapped.

Disclosure of Invention

The present utility model is directed to overcoming the problems in the prior art as described above, and providing a differential assembly with an anti-rotation structure for a planetary wheel spacer; the differential mechanism mainly solves the problem that the damage of the differential mechanism assembly is caused by overlarge abrasion of a planetary wheel pad and a differential shell of the existing differential mechanism assembly under the severe working condition.

The technical scheme provided by the utility model is as follows: a differential mechanism assembly with a planetary gear gasket anti-rotation structure comprises a planetary gear, a planetary gear gasket, a half-axle wheel, a cross axle, a differential mechanism left shell and a differential mechanism right shell; the left differential case and the right differential case are connected together, a cross shaft is arranged in a middle hole of the left differential case and the right differential case, a planetary gear is sleeved on the cross shaft, half shaft wheels are arranged on two sides in the left differential case and the right differential case, the planetary gear is meshed with the half shaft wheels, the planetary gear rotates around the cross shaft, and the cross shaft drives the planetary gear to revolve; a planetary gear gasket is arranged between the planetary gear and the right differential gear shell; the planetary gear gasket is characterized in that a first stop plane is arranged on the right differential gear shell, a second stop plane is arranged on the planetary gear gasket, the second stop plane of the planetary gear gasket is clamped on the first stop plane of the right differential gear shell, the first stop plane limits the second stop plane, and then the planetary gear gasket does not rotate along with a planetary gear.

Further, the first stop plane of the right differential case is matched with the second stop plane of the planetary gear gasket, and when the differential is operated, no relative rotation is generated between the planetary gear gasket and the right differential case. Namely by limiting the relative rotation between the planetary wheel pad and the right differential case, the effect of pad housing wear is reduced.

The utility model has the beneficial effects that: the planetary gear gasket with the stop surface and the differential right shell with the stop surface are adopted, so that relative rotation is prevented between the planetary gear gasket and the differential shell, abrasion of the differential shell is reduced, the differential shell is prevented from being excessively worn, the meshing gap between a differential side gear and the planetary gear is increased, and the gear is toothed due to excessively large meshing dislocation.
