A vehicle suspension system

摘要

A wheel support knuckle and trailing arm assembly that is attached to a toe link of a vehicle suspension system. The trailing arm assembly is formed by a blade member and a reinforcement member. The wheel support knuckle defines an axle bore and includes an integrally formed upper link receptacle and an integrally formed brake caliper track. The toe link is retained on the trailing arm assembly by a clevis formed by a transverse wall formed in the blade member and a parallel transverse wall formed in the reinforcement member. An alternative embodiment discloses a one-piece trailing arm that defines a clevis for connection to the toe link between a transverse wall and a tab that extends parallel to the transverse wall. A method of making cast wheel support knuckle and stamped trailing arm assembly is also disclosed.
