Abstract

A steering knuckle, including a rod part, a disc part, an ear part including a first ear and a second ear. The rod part and the ear part are disposed on two sides of the disc part, respectively. The first ear is longer than the second ear. The first ear and the second ear each include a pin hole; the connection line of two pin holes of the first ear and the second ear is perpendicular to the axis of the rod part. The first ear extends parallel to the axis of the rod part in the direction away from the disc part to form a pulling arm configured to connect to a steering drag link. The second ear extends perpendicularly to the axis of the rod part and perpendicularly to the connection line of the two pin holes to form a steering arm configured to connect to a steering tie rod.
