Description

이륜차량 브레이크Two-wheeled vehicle brake

본 발명은 이륜차량 브레이크에 관한 것으로서, 특히 전륜 브레이크 및 후륜브레이크로된 이륜차량 브레이크에서 유압식과 기계식으로 된 후륜 이중 브레이크 대신 단순 유압식 브레이크이면서 완벽한 브레이크 작동이 가능한 브레이크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-wheeled vehicle brake, and more particularly, to a brake that is a simple hydraulic brake and capable of perfect brake operation, instead of a hydraulic and mechanical rear wheel double brake in a two-wheeled brake with front and rear brakes.

종래에는 전후륜 브레이크 장치가 장착된 이륜차량에서의 다중 브레이크는 유압식 전륜 브레이크외에 후륜 브레이크로서 도5에 도시된 바와 같이 둥근 밴드브레이크슈(47)의 표면에 브레이크 라이닝(44')을 부착한 것을 브레이크 드럼(50)내에 내장하여 브레이크 파이프(11')의 좌우 작동에 의한 캠(48)의 좌우 회동과 양측브레이크슈(47)에 연결된 리턴 스프링(46)의 팽창 수축 작용에 의해 브레이크 라이닝(44')이 부착된 브레이크슈(47)가 그것의 상측에 앵커(49)를 앵커축(49a)으로 지지하면서 양측으로 확개 또는 수축하여 브레이크 라이닝(44')의 마찰력을 브레이크드럼(50)에 부가하거나 해제하면서 브레이크 역할을 하도록 구성된 것이 있으나, 이 경우 신품일 경우외에는 라이닝(44')의 마모나 드럼(50)의 마모로 분진이 발생하여 그 드럼 내부에 끼어 있게 되고 마찰부위의 불균형으로 브레이크의 원래 기능을 발휘하지 못하고 사고의 위험이 수반되게 되며, 또한 일정기간 사용후에는 브레이크를 수시로 조절해 주지 않으면 브레이크의 제동작용이 용이치 못하며, 일반적으로 드럼의 청소나 체인조정 및 베어링 교환, 타이어 펑크 시에도 브레이크는 항상 조절 보완하여야 하는 불편이 있었다.Conventionally, a multiple brake in a two-wheeled vehicle equipped with a front wheel brake device is a rear wheel brake in addition to a hydraulic front wheel brake, in which a brake lining 44 'is attached to the surface of a round band brake shoe 47 as shown in FIG. Brake lining 44 by the left and right rotation of the cam 48 by the left and right actuation of the brake pipe 11 'and the expansion and contraction action of the return spring 46 connected to both side brake shoes 47 built in the brake drum 50. ') Is attached to the brake shoe (47) is extended or contracted to both sides while supporting the anchor 49 to the anchor shaft (49a) on its upper side to add the friction force of the brake lining (44') to the brake drum (50) It is configured to act as a brake while releasing or releasing, but in this case, the dust is generated due to the wear of the lining 44 'or the wear of the drum 50 except the new one, which is caught inside the drum. Due to the imbalance of the friction part, the brake does not perform its original function and the risk of an accident is accompanied. Also, if the brake is not adjusted frequently after a certain period of time, braking of the brake is not easy. Even during adjustment, bearing replacement, and tire puncture, the brakes were always inconvenient to be adjusted.

뿐만 아니라 라이닝이 마모된 상태를 육안으로 볼수가 없으므로 마모된 상태로 운행하다가 급브레이크를 잡아야할 경우 위험이 뒤따르게 된다.In addition, since the lining is worn out, it is not visible to the naked eye, so if you need to catch the brakes while driving in worn condition, the danger will follow.

또한 라이닝(44')의 파열, 압축 및 리턴스프링(46)의 단절에 의한 고속중의 급제동시 브레이크의 원위치 미달등으로 상당한 위험이 수반되며 브레이크 라이닝(44')을 교환 수리하고져 할 때는 후륜을 모두 분해해야만 브레이크를 수리할 수가 있는 번거로움이 있으며, 또한 상기와 같은 종래의 밴드 브레이크는 브레이크 라이닝(44')과 드럼(50) 사이에 굉음이 발생하여 승차자의 신경을 자극하게 되며, 라이닝의 마모와 드럼의 마모로 브레이크의 원터치 즉 브레이크 제동전의 원위치로 환원되지 않으므로 인하여 오토바이의 엔진에 무리가 가해짐은 물론 승차자의 정신적 부담감마져 주게 된다.In addition, there is considerable danger due to the failure of the brake in the original position during high-speed braking due to rupture of the lining 44 ', compression and disconnection of the return spring 46. When the brake lining 44' is replaced or repaired, It is a hassle to repair the brakes only after disassembling all of them, and the conventional band brakes as described above generate noise between the brake lining 44 'and the drum 50 to stimulate the rider's nerves. The wear and drum wear are not reduced to the one-touch position of the brake, that is, before the brake braking, so that the engine of the motorcycle is not overwhelmed and the mental burden of the rider is exerted.

또 종전의 드럼 브레이크는 브레이크의 패달 사이가 금속로드로 연결되어 있어서 역시 파손등 위험 부담이 많았었다.In the past, the drum brakes were connected with metal rods between the pedals of the brakes, which was a risk of damage.

또한 상기와 같은 종래의 이륜차량 브레이크의 결점을 보완 개량한 것으로서 도4에서 참조되는 바와 같이 이륜차량의 전륜에는 수동레버에 의해 작동되는 유압식 브레이크(미도시)가 통상적인 구조로 장착되고 후륜과 전륜에는 유압공급라인(11a)에 의하여 유압 공급장치(39)가 전후륜의 브레이크 드럼(50)에 장착된 유압식 브레이크(42)내의 유압식 브레이크 디스크(20)와 연결되어 패달(12)과 연결간(13)에 의해서 작동되는 다중 브레이크로 구성된 것이 있으나 이는 전후방의 유압식 및 밴드브레이크등의 다중 제동장치에 따른 작동상의 복잡성과 부품의 조립 및 해체, 교환등이 번거럽고 고장의 우려가 많은 결점이 있었다.In addition, as a reference to FIG. 4, the front wheel of the two-wheeled vehicle as a complementary improvement of the drawbacks of the conventional two-wheeled brake as described above is equipped with a hydraulic brake (not shown) operated by a manual lever in a conventional structure, and the rear and front wheels. By the hydraulic supply line 11a, the hydraulic supply device 39 is connected to the hydraulic brake disc 20 in the hydraulic brake 42 mounted on the brake drum 50 of the front and rear wheels, thereby connecting the pedal 12 and the connection ( It is composed of multiple brakes operated by 13), but it has many defects such as troublesome operation and complicated assembly, disassembly, and replacement due to multiple braking devices such as front and rear hydraulic and band brakes.

본 발명은 상기와 같은 종래의 이륜 차량의 브레이크장치의 복잡성과 고장성을 탈피하여 간편하면서도 제동작용이 완벽하고 조립, 부품 수리 및 교체등의 취급이 간편 용이한 이륜차량의 브레이크를 제공코져 하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention is to provide a brake of a two-wheeled vehicle that deviates from the complexity and failure of the brake device of the conventional two-wheeled vehicle as described above, yet has a complete braking action and is easy to handle such as assembly, parts repair and replacement. This will be described in detail with reference to the accompanying drawings.
