Half shaft used for rear bridge of electric automobile

Abstract

The invention relates to a half shaft, in particular to the half shaft used for a rear bridge of an electric automobile. According to the adopted technical scheme, the half shaft used for the rear bridge of the electric automobile is reasonable in structure; the half shaft is formed in a split welding manner; and compared with an ordinary half shaft, the half shaft has the beneficial effects that under the condition that the use effect is not influenced, materials are saved, the forging cost is reduced, the energy consumption is lowered, the forging difficulty is greatly lowered, machining labor hours are shortened, and the comprehensive manufacture expense of each half shaft is reduced by about 20%. The half shaft has the beneficial effects that the structure is reasonable, the half shaft is formed in the split welding manner, material saving is facilitated, the forging cost is reduced, the energy consumption is lowered, the forging difficulty is greatly lowered, and the machining labor hours are shortened.

Description

technical field [0001] The invention relates to a half shaft, in particular to a rear axle half shaft for an electric vehicle. Background technique [0002] Both ends of the rear axle steel pipe of the electric vehicle are provided with a half shaft for installing the wheel hub, which is an important part of the electric vehicle. The traditional semi-shafts for rear axles of electric vehicles are all integrally forged, which not only increases the cost of forging, but also increases energy consumption. The workload of the staff is heavy and the labor intensity is high, which greatly increases the cost of the semi-axles. Can not meet the needs of use. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a half shaft for the rear axle of an electric vehicle with reasonable structure and good use effect in view of the above-mentioned deficiencies. [0004] In...
