Description

방열성을 증대시킨 자동차용 브레이크 디스크( A brake disk for an automobile)A brake disk for an automobile with increased heat dissipation

본 고안은 자동차 디스크 브레이크의 디스크에 관한 것으로,특히 디스크에 벤틸레이션 홈이 방사상으로 형성되고 이 벤틸레이션 홈에는 나선형의 보조홈이 형성되어 상기 벤틸레이션 홈으로 유입되는 공기가 와류를 형성하도록 함으로써 브레이크 디스크의 방열효과를 개선한 자동차 브레이크 디스크에 관한 것이다.The present invention relates to a disc of an automobile disc brake, and in particular, a ventilation groove is radially formed in the disc, and a spiral auxiliary groove is formed in the ventilation groove so that the air flowing into the ventilation groove forms a vortex. The present invention relates to an automobile brake disc with improved heat dissipation effect.

자동차의 브레이크는 구조에 따라 드럼식 브레이크와,디스크 브레이크로 대별된다.Automobile brakes are roughly classified into drum brakes and disk brakes, depending on the construction.

그런데 브레이크를 반복하여 작동하면 브레이크 라이닝이 드럼과 반복마찰하면서 고온의 열을 발생시키게 되고 이 마찰열로 인하여 브레이크 라이닝의 마찰계수가 변화하여 제동능력이 떨어지는 문제점이 있었다.However, when the brake is repeatedly operated, the brake lining generates frictional heat with the drum repeatedly, and the friction coefficient of the brake lining changes due to the frictional heat.

이와 같이 마찰열에 의해 제동능력이 떨어지는 문제점을 개선하여,드럼형 대신에 접촉면이 외부로 노출되어 마찰열을 방출시키도록 된 디스크형을 사용하는 디스크 브레이크가 고안되어 사용되고 있다.In this way, a problem in which the braking ability is lowered by frictional heat is improved, and a disc brake using a disc type, in which a contact surface is exposed to the outside instead of a drum type, to release frictional heat, has been devised and used.

더욱이 상기 디스크 브레이크의 디스크에 벤틸레이션 홈을 형성시킨 벤틸레이션형 브레이크 디스크가 고안되어 방열성을 개선하였다.Furthermore, a ventilation type brake disc having a ventilation groove formed on the disc of the disc brake has been devised to improve heat dissipation.

그러나 상기 종래의 벤틸레이션형 브레이크 디스크는 벤틸레이션 홈이 단순히 외측 선단에서 중심방향을 향하는 방사형으로 형성되어 있어 그 홈을 따라 유입되는 공기는 곧바로 빠른 속도로 지나가기 때문에 브레이크 디스크를 충분히 방열냉각시켜 주지 못하는 문제점이 있었다.However, in the conventional ventilation type brake disc, the ventilation groove is simply formed radially from the outer end toward the center, so that air flowing along the groove passes at a high speed so that the brake disc is sufficiently radiated and cooled. There was a problem.

이에 본 고안은 상기 종래의 벤틸레이션형 브레이크 디스크가 가진 단점을 해소하기 위해 안출된 것으로 벤틸레이션 홈으로 유입되는 공기가 와류를 일으킴으로써 방열효과가 증대되도록 한 자동차 디스크 브레이크의 디스크를 제공함에 그 목적이 있다.The present invention has been made to solve the drawbacks of the conventional ventilation type brake discs to provide a disc of the car disc brake to increase the heat dissipation effect by causing the air flowing into the ventilation groove to vortex. There is this.

상기한 목적을 달성하기 위한 본 고안은 브레이크 디스크에 방사형으로 형성된 벤틸레이션 홈에 나선형 보조홈이 형성되어 이 벤틸레이션 홈을 따라 유입되는 공기가 와류를 형성하는 구조로 되어 있다.The present invention for achieving the above object has a structure in which a spiral auxiliary groove is formed in the ventilation groove radially formed in the brake disc to form a vortex of air introduced along the ventilation groove.

그리고 상기 벤틸레이션 홈(4)은 나선형의 보조홈(5)이 구비되어 상기 벤틸레이션으로 유입되는 공기가 와류를 형성하게 되는 것이다.In addition, the ventilation groove 4 is provided with a helical auxiliary groove 5 so that air introduced into the ventilation forms a vortex.
