Abstract: 본 발명의 무단 변속기인 CVT(Continuously Variable Transmission)에서 동력을 전달하는 벨트(3)가 밴드(20)를 결합한 세그먼트(10)에 밴드(20)와 세그먼트(10)의 접촉 반경 차를 선 속도 차와 더불어, 풀리와 세그먼트(10) 간 슬립(Slip)을 함께 고려하고, 밴드(20)가 삽입되어 안착되는 세그먼트 숄더(13)의 접촉 반경 차를 약 0.27mm가 되도록 설계해 줌에 따라, 밴드와 세그먼트 간 상대 속도 차를 없애고 특히, 실 차 운행 조건 중 가장 많이 사용하는 영역인 OD(Over Drive, 2000rpm)조건에서 밴드(20)와 세그먼트(10) 간 상대 속도 차를 없애, 동력 전달 효율과 연비 향상은 물론, CVT 내구성도 높여 줄 수 있는 특징이 있게 된다.

Abstract: PURPOSE: A gripper for a door is provided to be used for various kinds of vehicles because lower and upper vacuum cups are rotated depending on the restricted section of a door. CONSTITUTION: A gripper(100) for a door comprises a frame(10), lower vacuum cups(20), moving units(30), upper vacuum cups(50), and rotating units(70). The lower vacuum cups are installed in both sides of the bottom of the frame to be horizontally movable and vacuum-suck the bottom end of a vehicle component. The moving units horizontally reciprocate the lower vacuum cups. The upper vacuum cups are installed in both sides of the top of the frame and vacuum-suck the top end of the vehicle component. The rotating units are connected to the upper vacuum cups at the top of the frame and vertically rotate the upper vacuum cups.
