Abstract

본 발명은 자동차의 브레이크드럼 방열구조에 관한 것으로, 더욱 상세하게는 차축과 함께 회전하는 드럼 내측에 선택적으로 가압되어 제동을 이루는 드럼식 브레이크에 있어서, 상기 드럼에서 발생하는 고열을 냉각시키는 방열핀 구조의 개선에 관한 것으로서, 차축(10)고정되어 회전하는 드럼(20)과, 드럼내주연에 접촉하여 제동을 이루는 브레이크슈우(30) 및 브레이크라이닝(32)을 구비하고, 상기 드럼(20)주연에 반경방향 외측으로 돌출구성되어 브레이크라이닝(32)과 드럼(20)의 마찰열을 외부로 방출하는 방열핀(22)을 형성함에 있어서, 상기 드럼의 일측에 형성되는 테이퍼면(24a)과, 상기 드럼(20)주연 및 상기 테이퍼면(24a)에서 반경방향 외측으로 돌출구성되는 수개의 방열핀(22)과, 상기 각각의 방열핀(22)상에 복수개의 방열구멍(22a)을 구비함을 특징으로 한다.The present invention relates to a brake drum heat dissipation structure of an automobile, and more particularly, in a drum brake configured to brake by selectively being pressed inside a drum rotating together with an axle, to improve a heat dissipation fin structure that cools high heat generated in the drum. Regarding, the axle (10) is provided with a rotating drum 20, a brake shoe 30 and a brake lining (32) for braking in contact with the drum inner peripheral, the radius around the drum 20 Protruding outward in the direction to form a heat radiation fin 22 for releasing the frictional heat of the brake lining 32 and the drum 20 to the outside, the tapered surface (24a) formed on one side of the drum, the drum 20 And a plurality of heat dissipation fins 22 protruding radially outward from the peripheral and tapered surfaces 24a, and a plurality of heat dissipation holes 22a on each of the heat dissipation fins 22. The.
