A vehicular hybrid suspension arm includes a suspension arm body made of a steel material, and an insert molding inserted into and coupled to the suspension arm body, providing a suspension arm having reduced weight and high rigidity.

Vehicular hybrid suspension arm and manufacturing method thereof

A hybrid lower arm and a hybrid upper arm include an arm body made of a metal material, and an insert injection-molded integrally with the arm body so that the insert is inserted into an inside of the arm body. The arm body has a weight ratio of 50% or more and 90% or less with respect to the total weight of the hybrid lower arm or the hybrid upper arm, thus achieving the rigidity increase as well as the weight reduction in the lower arm and the upper arm of a suspension system.

Hybrid suspension arm

A hybrid arm according to an embodiment of the present disclosure may include: a first body made of a metal material and formed with a plurality of end portions; a second body formed so as to fill an inner side of the first body by being insert-injection-molded to the first body; and a ball joint formed integrally at a first end portion among the plurality of end portions of the first body. The ball joint may include: a reinforcement member coupled to the first end portion; a bearing member formed with a space therein; a ball stud including a ball rotatably inserted into the space of the bearing member and a rod extending upward of the ball; and a housing interposed between the reinforcement member and the bearing member and formed integrally with the second body.
