Automobile steering knuckle as well as steering knuckle positioning and fastening device

Abstract

The invention provides an automobile steering knuckle as well as a steering knuckle positioning and fastening device. The automobile steering knuckle comprises a steering knuckle body in which a steering shaft hole is formed, wherein a first positioning part, a second positioning part and a third positioning part which are arranged in a triangular shape are formed on the steering knuckle body; the first positioning part and the second positioning part are clamping and fixing parts which are formed on the steering knuckle body and can be connected with an external mechanism in a clamping manner; one of the clamping and fixing parts is in a strip shape; and the third positioning part can be abutted and connected with the external mechanism. The invention also provides a steering knuckle positioning and fastening device for positioning and fastening the automobile steering knuckle. According to the automobile steering knuckle disclosed by the invention, complete positioning of the steering knuckle can be achieved by the arrangement of the first positioning part, the second positioning part and the third positioning part to guarantee stable positioning and fastening of the steering knuckle; and besides, the structure of a steering knuckle positioning and fastening fixture can be simplified, so that the problems that the design is difficult and collision accidents are easy to occur caused by complicated structure of the fixture can be solved, and the automobile steering knuckle is good in practicability.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile steering knuckle. The invention also relates to a steering knuckle positioning and clamping device for positioning and clamping the automobile steering knuckle. Background technique [0002] At present, the positioning of the steering knuckle of the car is mostly realized through the three boss structures provided on the steering knuckle, as well as the outer peripheral surface and the side structure of the bracket formed on the steering knuckle. The three boss structures can limit X and Y directions. The rotation of the steering knuckle and the movement in the Z direction, the structure of the outer circumferential surface can limit the upward movement of X and Y, and the side of the bracket can limit the rotation of the Z direction, so that the complete positioning of the six degrees of freedom of the steering knuckle in the X, Y and Z directions can be r...

AI Technical Summary

Problems solved by technology

[0003] For the steering knuckle adopting the above positioning structure, because there are many positioning structures on the steering knuckle, the existing fixture structure for positioning and clamping the steering knuckle includes a fixture body, an angular positioning mechanism, and a main support pressing mechanism. , auxiliary oil cylinder, solenoid valve and other components, the fixture structure is relatively complex, the space is compact, and it is not easy to design. Knife collision accidents often occur during the debugging stage, which may easily cause tool scrapping and fixture damage
