Description

마모 보정구조를 갖는 차량용 디스크 브레이크 {DISK BRAKE FOR VEHICLE WITH WEAR COMPENSATION STRUCTURE}Disc brake for vehicle with wear compensation structure {DISK BRAKE FOR VEHICLE WITH WEAR COMPENSATION STRUCTURE}
본 발명은 마모 보정구조를 갖는 차량용 디스크 브레이크에 관한 것으로, 보다 구체적으로 리테이너와 패드 사이에 위치하는 판 스프링의 내부강도를 증대시켜 판 스프링이 마찰에 의해 마모되는 것을 방지하기 위한 마모 보정구조를 갖는 차량용 디스크 브레이크에 관한 것이다.The present invention relates to a disc brake for a vehicle having a wear compensation structure, and more specifically, to increase the internal strength of the leaf spring located between the retainer and the pad having a wear compensation structure to prevent the leaf spring is worn by friction It relates to a disc brake for a vehicle.

일반적으로 차량의 동작을 제동하기 위해 사용되는 디스크 브레이크는 크게 브레이크 패드, 리테이너와 상기 브레이크 패드와 리테이너 사이에 위치하여 리테이너로부터 작용되는 힘에 의해 브레이크 패드에 힘을 제공하는 판 스프링으로 이루어진다. Disc brakes generally used to brake the operation of a vehicle are largely comprised of a brake pad, a retainer and a leaf spring positioned between the brake pad and the retainer to provide force to the brake pad by a force acting from the retainer.
종래에는 브레이크의 반복적인 동작에 의해 브레이크 패드와 리테이너 사이에 위치하는 판 스프링 중에서도 브레이크 패드와 리테이너 사이에서 접촉되는 영역에 마모가 발생하게 된다. 이로 인해, 판 스프링에 발생되는 스프링 텐션이 감소되고, 초기 텐션의 변화로 인한 제동력이 감소되는 문제점이 발생할 뿐 아니라, 판 스프링에 마모가 발생하여 판 스프링이 절단되는 상황이 발생하기도 한다. 이를 위해, 판 스프링의 주기적인 교체를 필요로 한다. 아울러, 판 스프링이 마모되어 판 스프링이 절단된 경우, 브레이크가 제동 작동을 수행할 수 없어 대형사고가 발생할 수 있는 문제점이 있다.Conventionally, abrasion occurs in the area contacted between the brake pad and the retainer among leaf springs positioned between the brake pad and the retainer by the repetitive operation of the brake. As a result, the spring tension generated in the leaf spring is reduced, and the braking force due to the change in the initial tension is reduced, as well as a situation in which the leaf spring is cut and the leaf spring is cut. To this end, periodic replacement of the leaf spring is required. In addition, when the leaf spring is worn because the leaf spring is cut, there is a problem that a large accident can occur because the brake can not perform the braking operation.

따라서, 본 발명의 목적은 판 스프링의 내부강도를 증대시켜 판 스프링의 마모 속도를 늦추고, 판 스프링의 수명을 연장시키기 위한 마모 보정구조를 갖는 차량용 디스크 브레이크에 관한 것이다.Accordingly, an object of the present invention is to provide a disc brake for a vehicle having a wear compensation structure for increasing the internal strength of the leaf spring to slow down the wear rate of the leaf spring and extending the life of the leaf spring.

또한, 상기 판 스프링은 상기 제1 영역의 양 측면에 날개부가 형성되고 상기 제1 영역의 상부방향으로 절첩되는 것을 특징으로 한다.In addition, the leaf spring is characterized in that the wings are formed on both sides of the first region and folded in the upper direction of the first region.
또한, 상기 판 스프링은 상기 제1 영역의 한 측면에 날개부가 형성되어 상기 제1 영역의 상부방향으로 절첩되는 것을 특징으로 한다.In addition, the leaf spring is characterized in that the wing is formed on one side of the first region is folded in the upper direction of the first region.
또한, 상기 판 스프링은 상기 제1 영역의 측면에 톱니형태의 날개부가 형성되어 상기 제1 영역의 상부방향으로 절첩되는 것을 특징으로 한다.In addition, the leaf spring is characterized in that the wing portion of the sawtooth shape is formed on the side of the first region is folded in the upper direction of the first region.
또한, 상기 판 스프링은 상기 제1 영역을 감싸는 커버부재를 더 구비하는 것을 특징으로 한다.In addition, the leaf spring is characterized in that it further comprises a cover member surrounding the first area.
또한, 상기 커버부재는 상기 판 스프링을 관통하여 제1 영역에 위치하는 것을 특징으로 한다. In addition, the cover member is characterized in that located in the first region through the leaf spring.

따라서, 본 발명은 판 스프링의 내부강도를 증대시켜 판 스프링의 마모 속도를 늦춰 판 스프링의 교체 시기를 연장시킬 수 있어 소모품인 판 스프링에 지출되는 비용절감의 효과가 있고, 판 스프링의 초기 텐션의 유지기간을 연장시킬 수 있는 효과가 있다.Therefore, the present invention can increase the internal strength of the leaf spring to slow down the wear rate of the leaf spring, thereby extending the replacement time of the leaf spring, thereby reducing the cost spent on the consumable leaf spring, and reducing the initial tension of the leaf spring. It is effective to prolong the maintenance period.

이로 인해, 본 발명에 따른 마모 보정구조를 갖는 차량용 디스크 브레이크는 브레이크 패드(10)와 리테이너(30)로 인하여 마찰이 발생되는 제1 영역(22)의 내부강도를 증대시켜 판 스프링(20)의 마모 속도를 늦춰 판 스프링(20)의 교체 시기를 연장시킬 수 있어 소모품인 판 스프링(20)에 지출되는 비용을 절감할 수 있는 효과가 있다. 또한, 판 스프링(20)의 초기 텐션 유지기간을 연장시킬 수 있는 효과가 있다.For this reason, the disc brake for a vehicle having a wear compensation structure according to the present invention increases the internal strength of the first region 22 in which friction occurs due to the brake pad 10 and the retainer 30, so that By slowing down the wear rate, the replacement time of the leaf spring 20 can be extended, thereby reducing the cost spent on the consumable leaf spring 20. In addition, there is an effect that can extend the initial tension holding period of the leaf spring (20).
이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 하기에 기재될 청구범위의 균등 범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
