본 발명의 서브프레임은 중공 홀이 뚫려진 마운팅 부시(10), 상기 중공홀의 내경에 밀착되는 상단 내측고정력(Aupper)과 함께 상기 마운팅 부시(10)가 눌러지는 상단외측고정력(Bupper)을 형성하는 마운팅 스터드(30), 상기 중공홀의 내경에 밀착되는 하단내측고정력(Alower)과 상기 마운팅 부시(10)가 눌러지는 하단외측고정력(Blower)을 형성하도록 상기 마운팅 스터드(30)와 나사 체결되는 마운팅 너트(40)로 구성된 마운팅 부시 유닛(1)을 포함함으로써 마운팅 부시(10)와 마운팅 스터드(30) 및 마운팅 너트(40)의 이중고정력에 의한 강한 체결력을 형성하고, 특히 상단/하단 내측고정력(Aupper,Alower)을 형성하는 원뿔형 구조로 조립공차와 함께 위치공차의 흡수가 이루어짐으로써 외부하중에 대한 서브프레임(100)의 회전과 강건성 유지로 차량 운동성능과 NVH 향상도 이루어지는 특징을 갖는다.

    The present invention relates to a mounting bush unit of an internal fixing type that can compensate an assembly tolerance by an internal fixing force, and a subframe. The mounting bush unit includes a mounting bush (10) having a through-hole; a mounting stud (30) which comes in contact with the inner peripheral surface of the through-hole to form an upwardly internal fixing force, and is pressed by the mounting bush to form an upwardly external fixing force; and a mounting nut (40) threaded with the mounting stud, the mounting nut coming in contact with the inner peripheral surface of the through-hole to form a downwardly internal fixing force, and being pressed by the mounting bush to form a downwardly external fixing force. A strong fastening force is generated by a double fixing force of the mounting bush, the mounting stud and the mounting nut. Since the mounting bush unit is formed in a conical shape, it is possible to compensate for a position clearance, as well as an assembly clearance.
