The present invention relates to a diaphragm of a pneumatic spring brake chamber for a vehicle. The diaphragm includes a wedge rim coupled between an adapter housing and a bottom housing, a flat plate adhered to a push rod plate, and a side curved part connecting the wedge rim and the flat plate to form a cup-shaped rotational body. The side curved part includes a first side curved part connected to a terminal end of the flat plate and extending downwards while being curved such that the center of curvature thereof can be located inside the rotational body, and a second side curved part connected to the wedge rim to be curved such that the center of rotation thereof can be located outside the rotational body. According to the present invention, the first side curved part and the second side curved part are formed on a side surface of the diaphragm and the center of curvature of the second side curved part is located outside the rotational body of the diaphragm so that the durability of the diaphragm can be enhanced and the air pressure of the chamber can be maintained constantly by preventing abnormal deformation of the diaphragm.

    본 발명은 차량용 공기압 스프링 브레이크 챔버의 다이아프레임에 관한 것으로서, 어댑터 하우징과 바텀 하우징 사이에 결합되는 ?지림부, 푸시로드 플레이트에 밀착되는 평판 및 ?지림부와 평판을 연결하는 측면곡선부를 구비하여 컵 형상의 회전체로 형성되고, 측면곡선부는 평판의 종단에 연결되어 회전체의 내측에 곡률중심이 위치하도록 곡률 형성되어 하방향을 향하여 연장되는 제1 측면곡선부 및 제1 측면곡선부의 종단에서 회전체의 바깥에 곡률중심이 위치하도록 ?지림부에 연결되어 곡률 형성되는 제2 측면곡선부;를 포함한다. 본 발명에 의하면, 측면부에 제1 측면곡선부 및 제2 측면곡선부를 갖도록 형성하고, 제2 측면곡선부가 다이아프레임 회전체 바깥에 곡률중심이 위치하도록 하여 다이아프레임의 이상변형을 방지하여 내구성 증대와 챔버 내의 공기압을 일정하게 유지시킬 수 있다.
