Commercial vehicle long-oil-change-cycle hub assembly and adjustment method thereof

Abstract

The invention belongs to the technical field of automobile manufacturing, and relates to a commercial vehicle long-oil-change-cycle hub assembly and an adjustment method thereof. The hub assembly is composed of tire bolts, a high-performance wearproof hub inner oil seal, a hub inner bearing assembly, a hub, a corrugated spacer bush, a hub outer bearing assembly, a shaft head nut, a shaft head nutlock plate, an assembly bolt and a high-performance wearproof hub outer oil seal. In the method, the shaft head nut is continuously tightened with specified torque, and thus the corrugated spacer bushbetween a hub outer bearing inner ring roller assembly and a hub inner bearing inner ring roller assembly generates irreversible plastic deformation; when the tension of the hub reaches a specified value, the shaft head nut is stopped from being tightened, and thus the shaft head nut, the hub outer bearing inner ring roller assembly, the corrugated spacer bush and the hub inner bearing inner ringroller assembly form an integrated rigid body. By means of the commercial vehicle long-oil-change-cycle hub assembly and the adjustment method thereof, the cost can be reduced while the maintenance mileage interval of an existing common hub assembly is greatly increased; the maintenance interval mileage is increased while the use performance is met, and maintenance is convenient and costs less.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a commercial vehicle long oil change hub assembly and an assembly method thereof. Background technique [0002] With the advancement of science and technology and the development of society, road transportation has developed into a very mature industry. Commercial trucks are the main vehicles of road transport, and their performance will directly affect the development of road transport. The axle is the main bearing and torque transmission assembly, which plays a pivotal role in the vehicle, while the wheel hub assembly is the main carrier for the drive axle to transmit torque, and its performance plays a vital role in the drive axle. Therefore, the wheel hub assembly with excellent performance, low cost, convenient maintenance, low maintenance cost and long maintenance mileage will definitely bring advantages to enterprises in the fierce market comp...

AI Technical Summary

Problems solved by technology

The maintenance mileage interval of ordinary wheel hub assemblies is (8000-12000) kilometers. Its advantage is that it is cheap, but its disadvantages are frequent maintenance and many parking vehicles. The maintenance-free wheel hub assembly commonly used in the market is Kangmai wheel hub assembly And FAG hub bearing unit, their maintenance mileage interval is (100,000-150,000) kilometers or life-long maintenance-free, the advantage is that the number of maintenance is small, the disadvantage is that the maintenance cost is high, and the hub assembly is expensive (3 times the price of ordinary hubs) times, or even higher)
