The present disclosure provides a hybrid suspension arm for a vehicle, having excellent durability. A hybrid suspension arm for a vehicle according to one embodiment of the present disclosure comprises: a suspension arm body which is made of metal material and comprises a top plate part and two sidewall parts extending downward from the top plate part to be open downward; and an insert molding which is made of plastic material and is formed by being insert-molded in the suspension arm body, wherein a thickness of at least a portion in the portion of the insert molding that comes in contact with the top plate part and the sidewall parts is in the range of 2 mm to 3 mm.

Hybrid suspension arm for vehicle

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.
