Vehicle drive axle assembly

Abstract

The invention discloses a vehicle drive axle assembly, and belongs to the technical field of vehicles. The vehicle drive axle assembly comprises a speed reducer shell, a bearing seat, a driving bevel gear, a first bearing and a second bearing, wherein the bearing seat is positioned in the speed reducer shell and is fixedly connected with the speed reducer shell, the driving bevel gear comprises a first bevel gear, a first shaft journal and a second shaft journal, the first shaft journal is connected to one side of the first bevel gear, the second shaft journal is connected to the other side of the first bevel gear, the first bearing is arranged on the first shaft journal in a sleeving mode and installed in the speed reducer shell, the inner surface of the first bearing is attached to the first shaft journal, the outer surface of the first bearing is attached to the speed reducer shell, the second bearing is arranged on the second shaft journal in a sleeving mode and installed in the bearing seat, and the inner surface of the second bearing is attached to the second shaft journal. According to the vehicle drive axle assembly, the space occupied by the assembled driving bevel gear, the first bearing and the second bearing in the axial direction of the first shaft journal is reduced, the compactness of the vehicle drive axle is facilitated, and then the vehicle axial arrangement space occupied by the vehicle drive axle assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle drive axle assembly. Background technique [0002] The drive axle of the vehicle includes a reducer, which is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed and increase the torque. [0003] In the prior art, the reducer includes a driving bevel gear and a driven bevel gear, and the driving bevel gear is arranged in the reducer housing with a cantilever structure, that is, the driving bevel gear is connected by two bearings on the same side of the driving bevel gear. The gears are assembled on the reducer housing. Specifically, two bearings are spaced and sleeved on the shaft diameter of the driving bevel gear. In order to avoid mutual interference between the two bearings, the two bearings need to reserve a large interval, resulting in a large size of the reducer in the axial direction of ...

AI Technical Summary

Problems solved by technology

In order to avoid mutual interference between the two bearings, the two bearings need to reserve a large interval, resulting in a large size of the reducer in the axial direction of the shaft diameter, so it needs to occupy more axial layout space of the vehicle, which is not conducive to Drive axle compactness
