Automotive disc-type steering joint integrated with steering arm and processing technology of steering joint

Abstract

The invention relates to the technical field of steering joints, in particular to an automotive disc-type steering joint integrated with a steering arm and a processing technology of the steering joint. The steering joint includes a rod part, a disc part and a lug part, the lug part includes a long lug and a short lug, the long lug and the short lug are provided with main pin holes respectively, and the steering arm, used for being connected with a steering transverse pulling rod, of the front end of the short lug stretches out from a plane perpendicular to the corresponding main pin hole to the lateral surface; the disc-type steering join is integrally forged and formed, and connecting arms, connected with brake calipers, of the long lug horizontally and separately stretch out from the plane where the disc part is located to the two sides, and form a T shape with the corresponding main pin hole. The automotive disc-type steering joint is scientific in structure; by directly integrating the steering arm with the disc-type steering joint, connecting devices are reduced; by extending the steering arm to be connected with other components, the structure of an automotive steering system is simplified, the novel disc-type steering joint of a lightweight structure is obtained, and more convenience is provided for achieving the lightweight automatic disc-type steering joint on the premise of ensuring the mechanical performance of a product.

Description

technical field [0001] The invention relates to the technical field of automobile steering knuckles, in particular to an automobile disc steering knuckle integrally formed with a steering arm and its processing technology. Background technique [0002] Steering knuckle is one of the main parts of the car. It effectively connects the braking system, steering system and suspension system through multiple parts, and plays the dual task of steering and carrying. It is an important safety part of the car chassis. The steering knuckle makes the car run stably and transmits the driving direction sensitively. At the same time, it needs to bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn. The steering knuckle is generally fork-shaped, including a rod part, an ear part, and a disc part. The ear part includes a long ear and a short ear, and the long ear and the short ear have kingpin holes for installing the kingpin. ...

AI Technical Summary

Problems solved by technology

This structure leads to a complex structure of the steering system of the car, and the overall weight is heavy, which is not only difficult to process, but also not conducive to the development trend of lightweight cars

For the disc steering knuckle, there is also a brake caliper connecting arm connected to the brake caliper. Due to the long length of the brake caliper connecting arm, this structure makes it more difficult to forge the steering knuckle
