Abstract

본 발명은 브레이크에 관한 것으로, 더 상세하게는 백플레이트에 설치된 브레이크슈를 지지하는 스프링과 핀을 일체로 마련한 드럼 브레이크에 관한 것이다.The present invention relates to a brake, and more particularly, to a drum brake integrally provided with a spring and a pin for supporting a brake shoe provided on a back plate.

본 발명은 백플레이트, 상기 백플레이트에 일단이 체결되고 체결된 일단을 중심으로 진퇴운동을 하며 그 몸체에는 관통공이 형성된 한 쌍의 브레이크슈, 상기 관통공을 관통하여서 백플레이트에 결합되어 브레이크슈를 지지하는 핀을 구비하는 드럼 브레이크에 있어서,The present invention is a back plate, one end is fastened to the back plate and the forward and backward movement around the fastened one end and the body is a pair of brake shoes formed through holes, through the through holes are coupled to the back plate to the brake shoes In a drum brake having a pin to support,

관통공에 대응되는 위치의 상기 백플레이트에는 결합공이 형성되고, 상기 핀은 탄성이 구비되며 일측은 상기 결합공에 결합되는 결합부, 타측은 상기 결합부를 지지하여 결합부가 백플레이트에서 이탈되는 것을 방지하는 지지부로 마련된 구성이다.A coupling hole is formed in the back plate at a position corresponding to the through hole, and the pin has elasticity, one side of the coupling part is coupled to the coupling hole, and the other side supports the coupling part to prevent the coupling part from being separated from the back plate. It is a configuration provided with a supporting part.
