Product knowledge

Steering knuckle, also known as “sheep horn”, is one of the important parts of automobile steering axle, which can make the automobile drive stably and transfer the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the vehicle is running, it bears changeable impact load, so it is required to have high strength.

The steering knuckle is connected with the vehicle body through three bushings and two bolts, and is connected with the brake system through the brake mounting hole of the flange. When the vehicle is driving at high speed, the vibration transmitted from the road surface to the steering knuckle through the tire is the main factor we consider in our analysis. In the calculation, the existing vehicle model is used to apply 4G gravity acceleration to the vehicle, calculate the support reaction force of the three bushing center points of the steering knuckle and the center points of the two bolt mounting holes as the applied load, and restrict the 123456 degrees of freedom of all nodes on the end face of the flange connecting the braking system.

The shape of the steering knuckle is relatively complex, which focuses on the structural characteristics of four types of parts such as shaft, sleeve, disc ring and fork frame. It is mainly composed of three parts: supporting journal, flange and fork frame. The structural shape of the supporting journal is a stepped shaft, which is characterized by a rotating body composed of a coaxial cylindrical surface, a conical surface, a threaded surface, and a shaft shoulder, a transition fillet and an end face perpendicular to the axis line; The flange plate comprises a flange surface, evenly distributed connecting bolt through holes and threaded holes for steering limit; The fork frame .
