본 고안은 드럼브레이크의 파킹레버에 관한 것으로서, 더욱 상세히는 드럼브레이크의 파킹레버의 구성의 개선에 관한 것이다.The present invention relates to a parking lever of a drum brake, and more particularly to an improvement in the configuration of the parking lever of the drum brake.
일반적인 드럼브레이크는 드럼내의 슈우가 유압실린더의 신축작동으로 드럼의 내벽면과 슈우상의 패드상 라이닝의 접속으로 제동을 수행하게 구성되고, 상기의 슈우와 힌지고정되는 파킹레버를 구비한다.A general drum brake is configured such that the shoe in the drum performs braking by connecting the pad-shaped lining on the inner wall surface of the drum and the shoe by the telescopic operation of the hydraulic cylinder, and has a parking lever hinged to the shoe.
파킹레버는 기구적인 작동가이드와 복원력을 부여하고 풋브레이크 이외에 주차용의 핸드브레이크와 연동하여 주차제동을 수행하기 위한 부재이다.The parking lever is a member that provides mechanical operation guide and restoring force and performs parking braking in conjunction with the hand brake for parking in addition to the foot brake.
종래의 상기의 파킹레버는 백플레이트상에 장착되는 슈우와의 작동거리의 제한을 하고 슈우위로 이복(履伏)하는 것을 방지하기 위하여 일방으로 돌출한 돌출핀을 일체형으로서 프레스가공 등의 방법으로 구비하게 되나, 이러한 타발형의 일체구성은 구조가 취약하고 고장이 빈발하는 문제점이 있었다.In the conventional parking lever, a press pin or the like is integrally formed with a protruding pin that protrudes in one direction in order to limit the working distance with the shoe mounted on the back plate and to prevent overshooting on the shoe. It is provided, but such a configuration of the punching type has a problem that the structure is weak and frequent failures.
상기와 같은 문제점을 감안하여 본 고안의 드럼브레이크의 파킹레버는 돌출핀을 개선하여 고장의 발생을 저감시킨 구성을 제공하는 것을 목적으로 한다.In view of the above problems, the parking lever of the drum brake of the present invention has an object to provide a configuration to reduce the occurrence of failure by improving the protrusion pin.
이하의 부수된 도면과 함께 본 고안의 드럼브레이크의 파킹레버를 종래 구성과 비교하여 더욱 상세하게 설명한다.The parking lever of the drum brake of the present invention together with the accompanying drawings will be described in more detail in comparison with the conventional configuration.
제1도는 일반적인 드럼브레이크를 도시하는 평면도 및 측단면도, 제2도는 종래의 드럼브레이크의 파킹레버를 도시하는 평면도 및 측면도, 제3도는 본 고안의 드럼브레이크의 파킹레버를 도시하는 평면도 및 측면도이다.1 is a plan view and a side sectional view showing a general drum brake, FIG. 2 is a plan view and a side view showing a parking lever of a conventional drum brake, and FIG. 3 is a plan view and a side view showing a parking lever of the drum brake of the present invention.
자동차의 드럼브레이크는 제1도에 도시된 바와 같이 드럼(1)내의 슈우(2)가 유압실린더(3)의 신축작동으로 드럼(1)의 내벽면과 슈우(2)상의 패드상 라이닝(4)의 접속으로 제동을 수행하고 이러한 제동은 드럼 내벽면과 슈우(2)상의 라이닝(4)으로 수행되며 라이닝(4)은 소모성 마찰재로 구성된다. 9는 저체부재가 장착되는 백킹플레이트이다.As shown in FIG. 1, the drum brake of an automobile has a pad-like lining 4 on the inner wall surface of the drum 1 and the shoe 2 by the expansion and contraction of the hydraulic cylinder 3 by the shoe 2 in the drum 1. The braking is carried out by the connection of) and this braking is carried out with linings 4 on the inner wall of the drum and the shoe 2 and the linings 4 are made of consumable friction material. 9 is a backing plate to which a body member is mounted.
파킹레버(5)는 슈우(2)와 함께 힌지지지고정점(7)에서 힌지연결되어 드럼(1) 내방에서 회동할 수 있다. 도시하지 아니한 주차브레이크케이블이 연결되어 주차제동을 수행하는 것이다.The parking lever 5 is hinged together with the shoe 2 and hinged at the vertex 7 so that the parking lever 5 can rotate inside the drum 1. Parking brake cable (not shown) is connected to perform parking brake.
상기와 같은 구성의 파킹레버(5)의 경우 슈우(2)에 대한 상대적인 변위의 제한과 슈우(2)위로 파킹레버(5)가 이복하지 않도록 일측단에는 돌출핀(10)을 프레스가공하여 타발성형하였다.In the case of the parking lever 5 configured as described above, the punching pin 10 is pressed at one end so that the displacement of the displacement relative to the shoe 2 and the parking lever 5 do not overturn the shoe 2. Molded.
그러나 상기와 같은 구성의 종래의 파킹레버(5)의 돌출핀(10)은 별도의 부재없이 단순히 프레스타발하여 돌출부로 만듬으로서 강고한 제동력이 반복적으로 수행되는 주차브레이크에서 돌출부위가 취악하여 소재판이 터져버리거나 부러지는 현상이 빈발하게 되어, 파킹레버(5)와 슈우(2)가 엉켜버리는 소위 "록킹"이 발생함으로서 브레이크의 파손이 유발되는 문제점이 있었다.However, the protruding pin 10 of the conventional parking lever 5 having the above-described configuration simply presses without a separate member to form a protruding portion, so that the protruding portion is vulnerable in the parking brake where strong braking force is repeatedly performed. There is a problem that the break or break occurs frequently, so that the so-called "locking" of the parking lever 5 and the shoe 2 is entangled to cause breakage of the brake.
상기의 문제점을 감안한 본 고안의 드럼브레이크의 파킹레버에서는 설계치에 따라서 상기의 돌출핀이 형성되어야 하는 부위값(1) 만큼 함입하여 파킹레버(15)의 형상을 구성하고 파킹레버(15)의 함입한 위치에서 절곡되는 절곡돌출핀(20)을 가지는 것을 특징으로 한다.In the parking lever of the drum brake of the present invention in consideration of the above-mentioned problems, the shape of the parking lever 15 is formed by incorporating as much as the part value 1 in which the above-described protruding pins are to be formed according to the design value, and the parking lever 15 is embedded. It is characterized by having a bending protrusion pin 20 is bent at one position.
절곡돌출핀(20)은 소정의 크기로하여 프레스절단한 뒤, 슈우(2)방향으로 "ㄱ"자형으로 절곡하여 줌으로서 종래의 돌출핀(10)과 같은 역할을 수행하게 된다.The bending protrusion pin 20 is press-cut to a predetermined size, and then bends in a "a" shape toward the shoe 2 to serve as a conventional protrusion pin 10.
이상의 본 고안의 드럼브레이크의 파킹레버에서와 같이 돌출핀을 돌출핀으로 대체함으로서 가공이 용이하고 상당한 두께의 소재판으로 제조되는 파킹레버의 경우 반복적인 사용에도 탈락하지 않게 되어 제동의 성능이 보장되는 유용한 고안인 것이다.As in the above-mentioned parking lever of the drum brake of the present invention, by replacing the protruding pin with the protruding pin, the parking lever which is easy to process and made of a material plate of considerable thickness does not fall off even after repeated use, thereby ensuring braking performance. It is a useful design.
