Problems solved by technology

The reducer on the rear axle is mostly a split structure, with large dimensions and complicated installation, and the space of the rear axle is limited, so it is very troublesome to arrange
In addition, the traditional split reducer has high manufacturing and design costs; the reducer has an input shaft, an intermediate shaft and a differential, and the input shaft is driven by the motor shaft of the drive motor, such as a spline connection, and the structure is relatively complicated

Embodiment Construction

[0011] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0012] combine figure 1 — image 3 As shown, an automobile rear axle assembly is mainly composed of rear axle 1, reducer 2 and driving motor 3.

[0013] The reducer 2 is mainly composed of a reducer housing 21 , an intermediate shaft 22 , a differential 23 and a bearing end cover 28 . The intermediate shaft 22 is provided with an intermediate gear, and the intermediate gear is meshed with the central gear on the differential 23 for transmission. Reducer housing 21 adopts integral casting, and the motor shaft of driving motor 3 stretches into the reducer housing 21 from the left side (or right side), and passes through the middle of the driving gear on the motor shaft and the intermediate shaft 22. Gear mesh transmission. The bearing end cover 28 is located on the side of the reducer housing 21 away from the drive motor shaft insertion hole 1 , and is ...

Abstract

The invention discloses an automobile rear axle assembly, which includes a rear axle, a reducer and a drive motor. The reducer includes a reducer casing, an intermediate shaft and a differential gear. The reducer casing is formed by integral casting, and the motor shaft of the drive motor It extends into the reducer housing from the left or right, and meshes with the intermediate gear on the intermediate shaft through the driving gear on the motor shaft. The drive motor is installed on the motor mounting flange of the reducer housing. The left half shaft is inserted into the left side of the differential, and the bevel gear on the left half shaft is driven by the bevel gear of the differential to rotate, and the right half shaft of the rear axle is inserted into the right side of the differential, driven by the bevel gear of the differential The bevel gear on the right half shaft rotates, and the reducer is connected to the rear axle through the rear axle mounting flange at the bottom of the reducer housing. Small size, convenient installation and low cost, the motor shaft of the drive motor is used as the input shaft; the gears of the transmission are all wrapped in the casing, with low noise, reducing the risk of oil leakage and saving lubricating oil.

Description

technical field [0001] The invention relates to an automobile rear axle structure and belongs to the technical field of automobile structures. Background technique [0002] Cars are divided into front-drive or rear-drive. The reducer is installed on the rear axle, the drive motor drives the reducer, and the reducer drives the left and right axles of the rear axle to rotate, which is the rear-drive type. Most of the reducers on the rear axle are split structures with large sizes and complicated installation. However, the space of the rear axle is limited and the arrangement is very troublesome. In addition, the traditional split reducer has high manufacturing and design costs; the reducer has an input shaft, an intermediate shaft and a differential, and the input shaft is driven by the motor shaft of the drive motor, such as a spline connection, and the structure is relatively complicated . Contents of the invention [0003] The present invention aims to provide an automo...
