description

The steering knuckle is the hinge for the steering of the wheels, generally in the shape of a fork. The upper and lower forks have two coaxial holes for installing the king pin, and the steering knuckle journal is used to install the wheel. The two lugs of the pin hole on the steering knuckle are connected with the fist-shaped parts at both ends of the front axle through the king pin, so that the front wheel can deflect a certain angle around the king pin to turn the car. In order to reduce wear, a bronze bushing is pressed into the steering knuckle pin hole, and the bushing is lubricated by the grease nipple installed on the steering knuckle. In order to make the steering flexible, a bearing is installed between the lower ear of the steering knuckle and the fist-shaped part of the front axle. An adjustment pad is also installed between the upper ear of the steering knuckle and the fist-shaped part to adjust the gap therebetween.
