Maintenance-free wheel end front axle of sectional structure

Abstract

The invention relates to a maintenance-free wheel end front axle of a sectional structure. The structure comprises a hub and a brake disc, the brake disc is arranged on the hub, and the hub comprises an inner hub and a hub outer hub cover; the brake disc is a Z-shaped brake disc, and the inner hub is an integrated hub; the inner hub is provided with an outer bearing inner ring, an inner bearing inner ring, a rolling body, a hub tile cover B, a Z-shaped brake disc binding face A, an integrated ABS gear ring, an O-shaped ring and a sealing ring, and the Z-shaped brake disc is provided with an inner hub binding face A, a hub tile cover matching face B, an outer hub cover binding face C, an embedded flange and a brake disc friction face; and an integrated hub cover and Z-shaped brake disc attaching face C is arranged on the hub outer hub cover, the inner hub, the Z-shaped brake disc and the hub outer hub cover are connected through hub connecting bolts, and tire bolts are arranged on the hub outer hub cover. Through the three-piece structure of the inner hub, the Z-shaped brake disc and the hub outer hub cover, convenient disassembly and assembly and maintenance-free are achieved.

Description

technical field [0001] The invention relates to a vehicle axle, in particular to a maintenance-free wheel-end front axle with a segmented structure. Background technique [0002] With the development trend of domestic passenger car technology and the continuous improvement of customers' requirements on the quality of axles, especially the requirements on after-sales maintenance and maintenance cycle of axles are becoming more and more stringent. At present, the shortcomings of the traditional front axle wheel hub assembly in the structure make it necessary for the front axle to be maintained and maintained regularly after a short period of operation, which will inevitably greatly increase the cost of use of the axle and reduce the frequency of use of the car. Due to the limitations of the traditional axle structure, the replacement of wearing parts such as brake discs is very troublesome. Contents of the invention [0003] The technical problem to be solved by the present...
