Abstract

The invention discloses a drive axle wheel end structure and a vehicle, and relates to the technical field of automobile axles. The drive axle wheel end structure comprises a half axle mechanism which comprises a half axle, an axle housing body and an axle head, a wheel hub, and bearings; and the axle housing body and the axle head are sequentially arranged on the half axle in a sleeving mode from inside to outside in the axial direction of the half axle; the wheel hub comprises an inner half wheel hub and an outer half wheel hub which are detachably connected, and the inner half wheel hub and the outer half wheel hub are sequentially arranged on the half shaft mechanism in a sleeving mode from inside to outside in the axial direction of the half shaft mechanism; the bearings comprise the inner bearing and the outer bearing, the inner bearing is installed between the axle housing body and the inner half hub, the two axial sides of the inner bearing abut against the inner half hub and the axle head respectively, the outer bearing is installed between the axle head and the outer half hub, and the two axial sides of the outer bearing abut against the axle head and the outer half hub respectively. The axial size of the shaft head can be reduced, the overall weight of the drive axle is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile axles, in particular to a drive axle wheel end structure and a vehicle. Background technique [0002] For the current drive axle used by the vehicle, the wheel end is provided with a shaft head, and a bearing and a wheel hub are sequentially sleeved outside the shaft head. At the same time, a lock nut structure is also provided on the outer end of the shaft head for fixing the bearing. However, this structure results in a larger axial dimension of the shaft head, and higher overall weight and cost of the drive axle. [0003] Based on this, there is an urgent need for a drive axle wheel end structure and a vehicle to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a drive axle wheel end structure and a vehicle, which can reduce the axial size of the shaft head, reduce the overall weight of the drive axle, and reduce the cost. ...
