Abstract

The invention belongs to the technical field of automobiles, and discloses a wheel-side reducer end face sealing structure, which includes a planetary carrier assembly, a half shaft, a sun gear, a screw plug and a ring gear, and the planetary carrier assembly includes a wheel-side reducer shell and a planetary carrier , Planetary gear shaft and planetary gear, the first end of the wheel reducer housing can be connected to the hub, the middle part of the second end of the wheel reducer housing forms a plug hole, and the planet carrier is sealed with the second end of the wheel reducer housing , the screw plug is sealed and connected to the opening of the second end of the wheel-side reducer housing, and is used to limit the sun gear in the axial direction. The outer circumference of the screw plug hole is also provided with a planetary shaft hole, and an O The ring is sealed. Beneficial effects of the present invention: by replacing the original end cover structure with the above structure, the production cost of the end cover and the processing cost of the wheel-side reducer shell are reduced; the sun gear is axially limited by the end face of the screw plug, and the original baffle is cancelled. , Adjusting gasket, snap ring combination limit structure, further reducing the cost.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an end face sealing structure of a wheel-side reducer. Background technique [0002] In domestic automotive wheel reduction drive axles, the end cover structure is mostly used for the sealing of the wheel reduction reducer, and multiple bolts are used to connect the end cover to the wheel reduction reducer shell, and baffles, adjusting gaskets, and snap rings are used. The combined structure is used for the axial limit of the sun gear. [0003] For example, patent document 1 (CN208138446U) discloses a wheel speed reducer, which includes a reducer housing, a sun gear located in the reducer housing, a planetary gear located in the reducer housing and meshed with the sun gear, and on the reducer housing A shaft hole is opened, and the shaft hole extends to the surface of the reducer housing. The planetary gear shaft is passed through the shaft hole. The planetary gear is sleeve...
