Abstract
The utility model discloses a rear axle brake assembly, which comprises a rear axle assembly, a brake oil pipe assembly, a rear sensor assembly, a rear brake assembly and a brake drum assembly, wherein the brake drum assembly consists of a brake drum, a gear ring, a stop bolt and a bearing; the stop bolt is pressed in the bolt hole in the brake drum; the gear ring is pulled on the brake drum; the bearing is pressed in the installation hole in the brake drum; the bearing is an angular contact ball bearing. The utility model further comprises a brake drum clamp spring that is positioned in a trough of the brake drum and props end of the bearing. The utility model applies an angular contact ball bearing instead of two independent inner bearings and outer bearings as previously practiced, and the spacer bushing is also saved, thus the utility model has a greatly simplified structure and is conveniently to assemble; besides, the originally independent oil seal is now integrated atop the bearing to give a more simplified structure and more convenient assembling works. The clamp spring is provided outside the bearing, in the trough of the brake drum, to limit position of the bearing, and the clamp spring does not stray out of the trough.
Description
[technical field]
The utility model relates to vehicular spare parts, relates in particular to the automobile axle brake assembly.
[background technology]
Brake drum assembly is mainly by brake wheel, gear ring, anti-turn screw, rear-wheel hub Oil sealing assembly, neck bearing and outer bearing in the existing automobile axle brake assembly.Adopt spacer to separate between neck bearing and the outer bearing, complex structure, the assembling trouble, and if the apolegamy of the size of spacer deviation is arranged, also can have influence on the rigging position of bearing, make between neck bearing and the brake wheel to have the gap, influence braking effect.Outside at bearing also will be provided with independently oil sealing, makes the single-piece structure complicated more, assembles more difficultly, and oil sealing easily runs out of, and loses its blocking effect.
So, how the structure of back axle brake assembly is reasonably improved, adopt simpler structure, make that assembling is simpler, the easier location of assembling, braking effect is more stable, reliable, becomes the important topic of industry technical personnel research.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of back axle brake assembly, and is simple in structure, easy to assembly, easily locatees during assembling.
For achieving the above object, the utility model proposes a kind of back axle brake assembly, comprise back axle assembly, the brake pipe assembly set, back sensor unit, rear brake assembly and brake drum assembly, described back sensor unit is fixed on the brake drum assembly, rear brake assembly is arranged on the brake drum assembly, be connected by the brake pipe assembly set between rear brake assembly and the back axle assembly, described brake drum assembly comprises brake wheel, gear ring, anti-turn screw and bearing, described anti-turn screw is pressed in the screw hole of brake wheel, gear ring is enclosed within on the brake wheel, and bearing is pressed in the mounting hole of brake wheel.
As preferably, described bearing adopts angular contact ball bearing.
As preferably, also comprise the brake wheel jump ring, described brake wheel jump ring is arranged in the groove of brake wheel, withstands the end of bearing.
As preferably, also comprise back sensor bolt of rear end plate, described back sensor bolt of rear end plate is fixed on the back sensor unit on the brake drum assembly.
As preferably, also comprise jam nut, described jam nut is arranged in the mounting hole of brake wheel, and the hole inner component is locked.
As preferably, also comprise block, described block is arranged on the mounting hole end of brake wheel, and the hole inner component is sealed.
The beneficial effects of the utility model: the utility model will adopt originally two independently neck bearing and outer bearing is improved to and adopts an angular contact ball bearing, and cancelled spacer simultaneously, structure is simplified greatly, assembling simultaneously easily can not produce the assembling deviation that is unworthy of causing because of the spacer size.Original independently oil sealing also is integrated in the end of bearing, integral structure is simplified more, assemble more convenient.Outside at bearing is provided with jump ring, and jump ring is stuck in the groove of brake wheel, and the position of bearing is limited, and jump ring can not run out of in groove, makes the performance of system more stable, reliable.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the structural representation of back axle brake assembly in the prior art;
Fig. 2 is the structural representation of the utility model back axle brake assembly.
[specific embodiment]
