Description

바퀴의 회전을 이용한 진공형성장치Vacuum forming device using wheel rotation

본 발명은 자동차의 진공배력장치에 관한 것으로, 특히 자동차의 주행중에 엔진이 갑작스럽게 운전정지되거나 혹은 주차된 자동차가 미끌어질 때에 바퀴의 회전을 이용해서 로터리펌프를 구동시켜 진공배력장치에 부압을 가하여 진공배력장치가 원활하게 제기능을 발휘할 수 있도록 된 바퀴의 회전을 이용한 진공형성장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum power booster for an automobile. In particular, when the engine suddenly stops driving while the vehicle is being driven or the parked vehicle slips, the rotary pump is driven using a rotation of the wheel to apply negative pressure to the vacuum power booster. It relates to a vacuum forming apparatus using the rotation of the wheel to enable the vacuum power booster to function properly.

일반적으로 차량은 대형화 및 고속확됨에 따라 브레이크 페달의 적은 답력으로도 차량을 확실하게 제동시킬 수 있도록 하기 위해 제동배력장치가 사용되고 있는 바, 이와 같은 제동배력장치가 제동력을 증대시키는 원리는 마스터 실린더와 별도로 파워 피스톤을 설치하고, 여기에 진공과 대기압과의 차압을 가하거나하여 힘을 증대시켜 큰 압력을 발생시키고 있다.In general, as a vehicle is enlarged and rapidly expanded, a braking power system is used to reliably brake the vehicle even with a small pedaling force of the brake pedal. The principle of increasing the braking power of the braking power system is based on a master cylinder. Power pistons are installed separately, and the pressure is increased by applying a differential pressure between vacuum and atmospheric pressure to generate a large pressure.

상기와 같은 제동배력장치는 진공과 대기압과의 차압을 이용하는 진공식 제동배력장치와, 압축공기압력을 이용하는 압축공기식 제동배력장치가 있는 바, 상기 진공식 제동배력장치는 엔진의 흡기매니폴드나 혹은 진공펌프에서 발생하는 부압과 대기압과의 차압을 배력장치내에 설치한 파워피스톤에 작용시켜 큰 힘을 브레이크에 가해주는 장치로서, 제1도에 개략적으로 단면도로 도시되어 있다.The braking booster includes a vacuum brake booster using a differential pressure between vacuum and atmospheric pressure, and a compressed air brake booster using compressed air pressure. The vacuum brake booster includes an intake manifold or an engine intake manifold. Alternatively, a device for applying a large force to a brake by applying a differential pressure between a negative pressure and an atmospheric pressure generated in a vacuum pump to a power piston installed in a power supply device, which is schematically illustrated in FIG.

즉 강판제로 만들어지는 파워 실린더(101)와, 이 파워 실린더(101)를 통해 돌출되면서 마스터 실린더(102)와 연결되어 조작력을 전달해주는 푸시로드(103), 이 푸시로드(103)와 밸브 플런저(104)사이에 부착되어 밸브의 개폐상태를 안정시키는 리액션 디스크(105), 상기 푸시로드(103)가 중앙에 설치되면서 실린더(101)와 기밀을 유지하도록 내장되는 파워피스톤(106), 이 파워피스톤(106)을 탄력적으로 지지하는 리턴스프링(107), 스프링(108)에 의해 탄력적으로 지지되면서 진공밸브(109)와 에어밸브(110)를 개폐시키는 포펫(111) 및, 한쪽이 상기 밸브 플러저(4)에 끼워지면서 다른쪽은 브레이크 페달과 연결되는 조작로드(112)를 갖춘 구조로 되어 있다.That is, a power cylinder 101 made of steel, a push rod 103 which protrudes through the power cylinder 101 and is connected to the master cylinder 102 to transmit an operating force, the push rod 103 and the valve plunger ( Reaction disk 105 attached between the 104 to stabilize the opening and closing state of the valve, the power rod 106 is installed to maintain the airtight with the cylinder 101 while the push rod 103 is installed in the center, the power piston A return spring 107 that elastically supports 106, a poppet 111 that opens and closes the vacuum valve 109 and the air valve 110 while being elastically supported by a spring 108, and one side of the valve plunger. While being fitted in (4), the other side has a structure having an operation rod 112 connected to the brake pedal.

이에 따라 브레이크 페달의 조작에 상응해서 상기 진공밸브와 에어밸브가 개폐되면서 파워피스톤의 양쪽 체임버사이의 차압력으로 파워피스톤을 밀어서 제동배력을 발생시켜주게 되어 있다.Accordingly, the vacuum valve and the air valve are opened and closed corresponding to the operation of the brake pedal to generate the braking force by pushing the power piston by the differential pressure between both chambers of the power piston.

그런데 상기한 종래의 진공식 제동배력장치에서는 엔진의 부압을 이용해서 진공을 형성시키거나 혹은 엔진에 의해 구동되는 진공펌프에 의해 진공을 형성시키고 있는 바, 자동차의 주행중에 예컨대 운전조작의 미숙으로 엔진의 운전이 급작스럽게 정지되거나 혹은 자동차의 주차시에는 진공이 전혀 형성되지 않기 때문에 브레이크 페달의 조작력이 배력되지 못해서 제동력이 약해지면서 다른 자동차와 충돌이나 추돌사고를 일으킬 염려가 있었다.However, in the conventional vacuum braking system, the vacuum is formed by using the negative pressure of the engine, or the vacuum is formed by a vacuum pump driven by the engine. Because of the sudden stop of driving or no vacuum at all when parking the car, the brake pedal's operating force could not be increased and the braking force was weakened, causing a collision or collision with other cars.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 엔진이 운전정지된 상태에서 자동차가 전진 또는 후진될 때에 바퀴의 회전을 이용해서 로타리펌프를 구동시켜 진공배력장치에 진공이 가하여 진공배력장치가 제기능을 발휘할 수 있도록 한 바퀴의 회전을 이용한 진공형성장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and when the engine is stopped or driven forward, the rotary pump is driven by using the rotation of the wheels when the vehicle is moved forward or backward to apply a vacuum to the vacuum power supply device. It is an object of the present invention to provide a vacuum forming apparatus using a rotation of one wheel to exhibit a proper function.

이하 본 발명의 실시예의 작용 및 효과를 설명한다.Hereinafter will be described the operation and effect of the embodiment of the present invention.

먼저 자동차의 주행중에 운전자의 운전조작미숙으로 엔진에 급격한 부하변동이 발생되면서 엔진의 운전이 정지된 상태로 주행되거나 자동차의 주차시에 외력이나 자중으로 주차브레이크가 풀리면서 자동차가 미끌어지면서 바퀴가 회전되면, 상기 각 릴레이스위치(6, 7)가 온되면서 밧데리 전원이 모우터(12)에 공급되게 되고, 이 모우터는 피니언기어(13)를 회전시킴과 더불어 이 피니언기어(13)와 랙기어(14)로 치합된 로타리펌프(3)는 직선이동되면서 2개의 클러치판(10, 11)이 서로 접속되게 된다.First of all, the driver's driving operation is immature and the engine suddenly changes its load and the engine stops running.
