본 개시는 차량용 현가 암에 관한 것이다. 현가 암은, 구형의 볼을 포함하는 볼 스터드, 볼이 수용되는 베어링, 내주부 및 외주부을 갖고, 내주부 내에 베어링이 수용되는 하우징, 하우징의 외주부에 결합되는 암 바디, 베어링의 하부 및 하우징의 외주부에 사출되어 베어링, 하우징 및 암 바디와 결합되는 인서트 몰딩부를 포함할 수 있다. 하우징에는 외주부의 상측에서 반경방향 외측으로 돌출되고, 금형과 접촉하도록 구성된 매칭면을 포함하는 매칭부가 형성될 수 있다. 매칭부가 형성됨으로 인하여, 금형과의 매칭면을 확보하는 동시에 하우징의 부피를 줄이고 현가 암의 중량을 저감할 수 있다.

    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.
