摘要： A suspension arm includes a ball stud including a spherical ball; a bearing in which the ball is accommodated; a housing having an inner peripheral portion, an outer peripheral portion, and a lower end portion that connects a lower end of the inner peripheral portion and a lower end of the outer peripheral portion, and configured to accommodate the ball and the bearing in a state in which the ball and the bearing are spaced apart from the inner peripheral portion; an arm body coupled to a portion of the outer peripheral portion of the housing; and an insert molding part formed on an outer peripheral portion of the bearing, the inner peripheral portion of the housing, and the lower end portion of the housing to couple the bearing with the housing. A convex-concave portion is formed on the inner peripheral portion of the housing along a circumferential direction.

摘要： 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.

摘要： 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.
