Problems solved by technology

In this context, since the use of integral forging or casting to manufacture support shafts can no longer meet the production requirements of multiple varieties and small batches, it is difficult to adapt to the development trend of manufacturing flexibility
Moreover, the method of integral forging or casting of steel to manufacture the support shaft requires casting or forging equipment with high one-time investment cost, so the production cost is relatively high

Embodiment Construction

[0046] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0047] The invention relates to a support shaft for a monolithic vehicle axle, where the monolithic vehicle axle can be either a supporting axle or a steering axle. For the supporting axle, the supporting shaft may not have a corresponding structure assembled with the steering knuckle, and for the steering axle, the supporting shaft may have a corresponding structure assembled with the steering knuckle (as according to the supporting shaft in the preferred embodiment of the present invention) shaft ends).

[0048] Such as figure 1 As shown, the support shaft for integral axle provided by the present invention includes a support shaft body 10, wherein, the supp...

Abstract

The invention relates to a supporting shaft for an integral type axle, the supporting shaft comprises a supporting shaft body, the supporting shaft body comprises a plurality of plate-like parts, and the plate-like parts are mutually welded, so that the supporting shaft body is in the shape of a hollow cross section. The manufacturing method for the supporting shaft for the integral type axle comprises the step of welding the plate-like parts which are prepared in advance into the supporting shaft body in the shape of the hollow cross section. The supporting shaft is difference with the traditional supporting shaft which is integrally molded, in the technical scheme of the invention, the supporting shaft body of the supporting shaft for the integral type axle is formed by welding the plurality of the plate-like parts and is in the shape of the hollow cross section. Therefore, the supporting shaft can be applicable to the requirement on flexibility of manufacturing, the cost is lower, and the supporting shaft can completely meet the requirements of application occasions of the supporting shaft.

Description

technical field [0001] The present invention relates to the field of vehicles, and more particularly, to a support shaft for an integral axle and a method of manufacturing the same. Background technique [0002] The axle is an important part of the vehicle. Usually, the vehicle axle is connected with the vehicle frame (or load-bearing body) through the suspension, and wheels are installed at the two ends of the vehicle axle. The vertical load on the frame is transmitted to the wheel through the axle; the rolling resistance, driving force, braking force, lateral force and its torque on the wheel are transmitted to the suspension through the axle. Therefore, the main function of the axle is It is to transmit the force and moment between the frame and the wheel. [0003] According to different structural forms of suspension, the axle can be divided into two types: integral type and disconnected type. For independent suspension, it is usually combined with a disconnected axle...
