The function of the steering knuckle is to bear the load of the front of the vehicle, and to support and drive the front wheel to rotate around the main pin. In the automobile driving state, it is under the changeable impact load, therefore, it has a very high strength. The steering knuckle is connected with the body through three Bushes and two bolts, and the brake system is connected with the brake system through the brake mounting hole of the flange disc.
