According to the present invention, a sub-frame module (1) comprises: a sub-frame (10) which comprises an upper plate (10-1) and a lower plate (10-2) combined in a boxing type and is penetrated by one or more vehicle body mounting holes (11, 13) having burring bosses (11-1, 13-1) perpendicular to the circumference of a hole; and a mounting bush (20) which has a hook flange (23-2) hooked to an outer pipe (23) press-fitted to the vehicle body mounting holes (11, 13) together with the burring bosses (11-1, 13-1). The present invention has advantages of removing an additional cup made of a steel material requiring welding which leads to corrosion, reducing weight in accordance with the removal of the cup made of a steel material and realizes a sub-frame modularization and a process simplification in accordance with the omission of the welding process.

    본 발명의 서브프레임 모듈(1)에는 박싱(Boxing)타입으로 결합된 상판(10-1)과 하판(10-2)으로 이루어지고, 홀의 둘레에 수직한 버링 보스(Burring Boss)(11-1,13-1)를 형성한 적어도 1개 이상의 차체 마운팅 홀(11,13)이 뚫려진 서브프레임(10)과, 차체 마운팅 홀(11,13)에 압입된 아우터 파이프(23)에 버링 보스(Burring Boss)(11-1,13-1)와 걸려지는 후크 플랜지(23-2)가 형성된 마운팅 부시(20)가 포함됨으로써 부식을 야기하는 용접이 필요하던 별도의 강재질 컵이 제거되고, 특히 강재질 컵 삭제에 따른 중량 저감과 용접 공정 삭제에 따른 서브프레임 모듈화 공정 단순화가 이루어지는 특징을 갖는다.
