  • Publication number: 20210114426
    Abstract: 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.

  • Publication number: 20210114427
    Abstract: A suspension arm includes a ball stud including a spherical ball; a bearing in which the spherical ball is accommodated; a housing having an inner peripheral portion and an outer peripheral portion; an arm body coupled to the outer peripheral portion of the housing; and an insert molding part which is injected to a lower portion of the bearing and the outer peripheral portion of the housing to be coupled to the bearing, the housing, and the arm body. The housing includes a matching portion having a matching surface formed to protrude in a radially outward direction from an upper portion of the outer peripheral portion and to be brought into contact with a mold. By forming the matching portion, it is possible to reduce the volume of the housing and to reduce the weight of the suspension arm while providing the matching surface with the mold.

  • Patent number: 10814535
    Abstract: 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.
