Abstract

The invention provides an automobile front axle assembly, and relates to automobile accessories. The automobile front axle assembly comprises a front axle, a brake assembly and a hub assembly which are respectively arranged at two ends of the front axle, wherein the hub assembly comprises a hub body, an outer bearing and an inner bearing which are arranged in the hub body; a brake boss is arranged on the hub body instead of a brake disc; friction plates are connected with left and right end faces of the brake boss, and thermal baffles are arranged between the friction plates and the brake boss; the outer bearing and the inner bearing are connected into a whole to form an integral unit bearing; and one or a plurality of through holes are formed in the front axle to realize light weight. According to the automobile front axle assembly, the brake disc is canceled in the hub assembly, and the friction plates and thermal baffles which are connected together with the hub body are adopted to replace the brake disc, so that the aims of production cost conservation, facilitated after-sale replacement and low maintenance cost can be achieved; and the whole axle has the characteristics of light weight, long service life, front axle bearing capacity guarantee, and is easy for popularization and application.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile front axle assembly. Background technique [0002] With the development of social economy, the demand for automobiles is increasing, and the competition among automobile manufacturers is also increasing. It is becoming more and more important for enterprises to reduce the production cost of auto parts and improve the convenience of after-sales maintenance. There are following deficiencies in the existing automobile front axle assembly: [0003] 1. The hub body and the brake disc of the hub assembly are cast separately first, and then connected together by the brake disc fastening bolts. The production cost is high, the after-sales replacement is difficult, and the weight is heavy. The specific performance is as follows: [0004] (1) Since the hub body and the brake disc need to be cast separately, the processing cost of the brake disc and the mold cost of the brake disc ...
