Problems solved by technology

[0002] The traditional half shaft of the drive axle adopts the integral structure of the flange and the shaft, such as figure 1 As shown, during production, the raw materials need to be forged through a die first, and the flange plate of the specified size is pierced, and then the flange plate and the shaft body are processed. The manufacturing process is complicated and the processing difficulty is high. If the size of the flange plate changes, it needs Remanufacturing molds, poor versatility and inconvenient use and maintenance of parts

Abstract

The invention provides a drive axle semi-shaft which comprises a semi-shaft body and a hub. The hub and the semi-shaft body are of a key connection mode structure. A nut locks the hub from one end. The key connection structure connects the semi-shaft body without a flange plate and the hub. Flange hubs of any size can by combined according to the requirements, a structure capable of transmitting torque and allowing a rim tire to be installed is formed, and therefore the portion in the direction, perpendicular to the semi-shaft body, of the outer circumference of the hub is provided with a step matched with a rim. The side wall formed by the step is connected with the inner wall of the rim. The inner wall of the rim and the side wall of the hub are compressed, connected and assembled into one through a bolt and a nut. The drive axle semi-shaft has the advantages that the structure is reasonable, manufacturing and processing are convenient and fast, the process is simple, the semi-shaft can be formed by directly processing and treating bars and plates in a heat mode, a mould is not needed for forging the flange plate, the manufacturing and processing cost is low, the manufacturing efficiency is greatly improved, connection is convenient, safe and reliable, the structural strength is good, and use and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a driving axle half shaft. Background technique [0002] The traditional half shaft of the drive axle adopts the integral structure of the flange and the shaft, such as figure 1 As shown, during production, the raw materials need to be forged through a die first, and the flange plate of the specified size is pierced, and then the flange plate and the shaft body are processed. The manufacturing process is complicated and the processing difficulty is high. If the size of the flange plate changes, it needs Remanufacturing molds has poor versatility and inconvenient use and maintenance of parts. Contents of the invention [0003] The purpose of the present invention is to provide a convenient manufacturing and processing, simple process, which can be directly processed by bar and plate and heat-treated, without the need for die forging pier flanges, which can be comb...
