AI Technical Summary
Technical Problem
The existing vehicle rear axle design is adapted to accommodate rear-wheel drive shafts of different sizes, which increases production and inventory costs and makes incorrect installation easy.
Method used
The symmetrical output shaft sleeve design allows only one model of rear wheel drive shaft to be produced. Stable transmission is achieved through symmetrical connecting splines and connecting spokes. Connecting bosses and reinforcing ribs are set on the side wall of the output shaft sleeve to enhance stability and torsional resistance.
Benefits of technology
This reduces inventory pressure and the risk of incorrect installation of production vehicles, lowers production costs, and improves installation efficiency and vehicle performance.

Abstract
This utility model provides a novel rear axle assembly, belonging to the field of vehicle rear axle technology. It solves the problems of inconsistent left and right matching transmissions, high inventory costs, and easy misinstallation in existing rear axle systems. This novel rear axle assembly includes a housing, a transmission gear set, and an output shaft sleeve. An end cover is provided on one side of the housing, and both the end cover and the housing have through external shaft holes. The output shaft sleeve is placed between these external shaft holes, which are coaxially aligned with the output shaft sleeve. Connecting bearings are provided at both ends of the output shaft sleeve. The transmission gear set has a gear disc and a gear shaft. Several connecting splines are symmetrically arranged on the inner wall of the output shaft sleeve. Connecting spokes are provided on the side wall of the output shaft sleeve, and connecting bolts are provided on the connecting spokes. The gear disc abuts against the connecting spokes. This utility model has the advantages of simple structure and cost reduction and efficiency improvement.
