본 고안은 브레이크 안전장치, 특히 제동배력장치를 구비한 브레이크장치의 브레이크 안전장치에 관한 것이다.The present invention relates to a brake safety device, in particular a brake safety device of a brake device with a braking booster.
일반적으로 브레이크장치에 있어서 제동배력장치는 브레이크페달에 작용하는 답력을 작게 하면서도 강력한 제동력을 얻기 위하여 브레이크장치의 피스톤에 작용시켜 제동력을 보조하여 주는 장치이다.In general, the braking force in the brake device is a device that assists the braking force by acting on the piston of the brake device to obtain a strong braking force while reducing the response force acting on the brake pedal.
이러한 제동배력장치는 엔진의 흡입부압이나 진공펌프에서 발생한 부압과 대기압이 압력차를 이용한 진공식과 컴프레셔에서 발생한 압축공기를 이용하는 압축공기식이 있으며, 본 고안은 진공식 제동배력장치를 구비한 브레이크장치의 안전장치에 관한 것으로, 흡기다기관내에 발생하는 부압과 대기압과의 압력차를 이용하여 배력작용을 하는 마스터백(master vac)또는 브레이크 부스터를 구비한 경우 엔진이 동작중인 경우에만 배압이 형성되기 때문에 엔진이 오프된 상태에서 배력이 형성되지 않아 제동력이 떨어져 언덕길에서의 주차시 차량중량에 의해 밀려내려오게 되어 사고가 발생되는 문제가 있었다.The braking power supply device is a vacuum device using the vacuum pressure and the vacuum pressure using the pressure difference between the negative pressure and atmospheric pressure generated from the suction pressure of the engine or the vacuum pump, the present invention is a brake device having a vacuum braking power system The safety device of the system is designed to provide back pressure only when the engine is operating when a master vac or brake booster is provided to operate by using the pressure difference between the negative pressure generated in the intake manifold and the atmospheric pressure. There was a problem in that an accident occurred because the braking force was not formed in the state in which the engine was turned off and the braking force was dropped and the vehicle was pushed down by the weight of the vehicle when parked on the hill.
제 1 도는 마스터밸을 구비한 배력장치(1)마스터실린더(2)가 일체로 구성된 진공식 일체형 제동배력장치를 도시하고 있으며, 배력장치(1)는 엔진(3)과 체크밸브(4)를 통하여 연통되어 있다. 배력장치(1)는 브레이크페달(5)에 의해 마스터실린더(2)로부터 각 휠에 장착된 브레이크장치에 압유를 공급하여 제동작용을 하도록 되어 있다.FIG. 1 shows a vacuum integrated brake system comprising a master cylinder (2) with a master valve (2) integrally equipped with a master ball, and the booster (1) provides an engine (3) and a check valve (4). Communicating through. The boosting device 1 supplies brake oil from the master cylinder 2 to the brake devices mounted on each wheel by the brake pedal 5 to perform a braking action.
그런, 제 1 도의 장치는 부압이 엔진동작시에만 형성되기 때문에 엔진이 오프된 상태에서는 부압이 형성되지 않아 배력장치는 유명무실한 상태로 될 수 밖에 없어 중량이 큰 예를 들어, 대형차의 경우 언더길 주차시 제동력이 떨어져 차가 밀려내려 오는 문제가 발생되거나, 또는 운전중 갑자기 시동이 오프되는 경우 브레이크 작동이 곤란하여 대형사고가 발생되는 문제가 있었다.However, since the negative pressure is only formed during engine operation, the apparatus of FIG. 1 has no negative pressure when the engine is turned off, so that the power booster is forced to become infamous. There was a problem that the car is pushed down due to the braking force during parking, or if the start is suddenly turned off while driving, the brake operation is difficult to cause a large accident.
본 고안의 목적은 상기한 종래의 진공식 배력장치를 구비한 브레이크장치의 문제점을 해소하도록 개선한 자동차용 브레이크 안전장치를 제공하는 것이다.It is an object of the present invention to provide an automobile brake safety device that is improved to solve the problems of the brake device with the conventional vacuum booster.
본 고안에 따른 브레이크용 안전장치는 엔진의 흡기다기관과 배력장치 사이에 체크밸브가 구비된 연결관을 통하여 부압의 에어탱크를 배설하여 배력장치에 향상 부압이 작용되도록 구성되어 있다.The brake safety device according to the present invention is configured so that the boost negative pressure is applied to the booster by disposing an air tank of negative pressure through a connecting pipe provided with a check valve between the engine intake manifold and the booster.
이하, 본 고안의 일실시예를 도시한 첨부도면을 참고하여 본 고안을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing an embodiment of the present invention.
제 2 도는 엔진(10)측의 흡기다기관에 연결된 배력장치(11)에는 도면에 도시되지 않은 각 휠의 브레이크를 작동하도록 압유를 공급하는 마스터실린터(12)가 일체로 형성된 브레이크장치의 구성을 개략적으로 도시하고 있다.2 shows a configuration of a brake device in which a power supply device 11 connected to an intake manifold on the engine 10 side is integrally formed with a master cylinder 12 for supplying pressure oil to operate a brake of each wheel not shown in the drawing. It is shown schematically.
엔진작동시 엔진의 흡기다기관으로 공기가 도입되며, 연결과(13)에는 엔진족으로의 공기흐름만 허용하며 그 역방향으로의 공기흐름은 허용하지 않는 체크밸브(14)가 제공되어 연결과(13)에는 항상 부압이 걸리게 되며 배력장치(11)는 그러한 부압이 브레이크페달(15)에 작용하는 답력과 함께 마스터실린더(12)의 피스톤에 작용하도록 되어 있다.During engine operation, air is introduced into the intake manifold of the engine, and the connection section 13 is provided with a check valve 14 which permits only air flow to the engine family and no air flow in the reverse direction. Negative pressure is always applied to the power supply unit 11 so that the negative pressure acts on the piston of the master cylinder 12 together with the step force acting on the brake pedal 15.
그러나, 상기 연결관(13)의 부압은 엔진이 동작중인 경우만 형성되므로 엔진이 돌발적으로 오프된 경우에는 부압이 형성되지 않아 제동력이 떨어지게 된다.However, since the negative pressure of the connecting pipe 13 is formed only when the engine is in operation, the negative pressure is not formed when the engine is accidentally turned off, so that the braking force drops.
본 고안에 따라, 엔진의 흡기다기관측에 연결과(16)을 통하여 배력장치(11)사이에 에어탱크(17)가 배설된다.According to the present invention, an air tank 17 is disposed between the power supply device 11 via a connection 16 on the intake manifold side of the engine.
상기 연결관(16)에는 체크밸브(18)가 제공되어 엔진시동시 에어탱크(17)내의 공기가 흡기다기관으로 유입되지만 역류되지 못하기 때문에 에어탱크(17)내에는 항상 진공상태의 부압이 형성되어 있으며, 엔진시동이 오프되더라도 에어탱크(17)의 부압이 브레이크페달의 답력과 함께 배력장치에 이용되므로 마스터실린더(12)에 작용되는 힘은 엔진의 시동에 관계없이 항상 일정하게 유지되므로, 주행중 엔진의 시동의 돌발적으로 오프되거나, 엔진시동을 끄고 언덕길에 주차하는 경우에도 에어탱크(17)의 부압에 의한 큰 제동력이 유지되어 종래와 같은 사고의 위험이 제거된다.The connecting pipe 16 is provided with a check valve 18 so that the air in the air tank 17 flows into the intake manifold when the engine is started, but since the backflow cannot be reversed, a vacuum negative pressure is always formed in the air tank 17. Since the negative pressure of the air tank 17 is used in the boosting device together with the pedal pedal effort even when the engine is turned off, the force acting on the master cylinder 12 is always kept constant regardless of the engine starting. Even when the engine is unexpectedly turned off or the engine is turned off and parked on a hill road, a large braking force by the negative pressure of the air tank 17 is maintained, thereby eliminating the risk of an accident as in the prior art.
