Abstract

The invention discloses an automobile steering knuckle structure and a machining process thereof and relates to the technical field of automobile parts and machining processes of the automobile parts.The automobile steering knuckle structure comprises a bearing journal, flange plates and a fork frame which are formed in an integrally forged mode, and the fork frame is composed of a lower swing arm connection pair, a steering gear push rod connection pair and an upper swing arm connection pair. The machining process comprises the following process steps of material detection, blanking, heatingblank-making, vertical forging, edge cutting, rectifying, heat treatment and electroplating. The automobile steering knuckle structure is optimized and improved, and an automobile steering knuckle produced through the machining process is more stable in quality and more reliable in structure.

Description

technical field [0001] The invention relates to the technical field of auto parts and its processing technology, in particular to an automobile steering knuckle structure and its processing technology. Background technique [0002] The steering knuckle is one of the main parts on the steering axle of the car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn. When the car is running, it bears variable impact loads. Therefore, it is required to have high strength. The steering knuckle is connected to the body through three bushes and two bolts, and through the brake steering knuckle mounting hole of the flange. Connected to the braking system. However, the structure of the traditional steering knuckle needs to be optimized. At the same time, the unreasonable design of some processing tec...
