4륜구동차량의 브레이크 안전장치Brake safety device for four wheel drive vehicle

본 발명은 4륜구동차량에 관한 것으로, 특히 4륜구동차량의 진공호스가 파손되어 진공이 작용하지 않을 경우에 서어지탱크와 파손된 진공호스라인을 차단하여 브레이크의 부우스터의 작동이 원만하게 이루어질 수 있도록 된 4륜구동차량의 브레이크 안전장치에 관한 것이다.The present invention relates to a four-wheel drive vehicle, in particular, when the vacuum hose of the four-wheel drive vehicle is broken, the surge tank and the broken vacuum hose line can be smoothly operated by blocking the surge tank and the broken vacuum hose line can be made smoothly. A brake safety device for a four-wheel drive vehicle.

일반적으로 4륜구동차량은 후륜으로 주행중에 운전자가 필요에 따라 전륜도 동시에 구동시켜 차량의 등판 능력 등을 향상시킬 수 있도록 되어 있는 데, 상기 전륜은 진공으로 작동되는 연결장치와 프리 휠 허브를 매개로 동력전달장치와 분리 가능하게 연결될 수 있도록 설치되어 있다.In general, four-wheel drive vehicles are designed to improve the climbing ability of the vehicle by driving the front wheels simultaneously as needed while the rear wheels are driven. The front wheels are connected by a vacuum-operated connection device and a free wheel hub. It is installed to be detachably connected to the power train.

도 1은 상기한 종래의 프리 휠 허브에 진공을 공급하고, 브레이크 부우스터에도 진공을 공급하기 위해 설치된 진공호스라인을 개략적으로 도시한 것인 바, 즉 서어지탱크(101)에 연결호스(102)를 매개로 진공탱크(103)가 연결되어 있고, 상기 진공탱크에는 프리 휠 허브로 진공을 공급하기 위해 공급호스(104)가 연결되어 있으며, 이 공급호스에는 스위치 조작에 따라 제어전류를 공급받아 작동되면서 상기 공급호스를 개폐시키는 솔레노이드밸브(105)가 설치되어 있다.FIG. 1 schematically illustrates a vacuum hose line installed to supply a vacuum to the conventional free wheel hub and to supply a vacuum to the brake booster, that is, a connection hose 102 to the surge tank 101. A vacuum tank 103 is connected to the vacuum tank, and a supply hose 104 is connected to the vacuum tank to supply a vacuum to the free wheel hub, and the supply hose receives a control current according to a switch operation. The solenoid valve 105 for opening and closing the supply hose while operating is installed.

또 상기 서어지탱크에는 브레이크 부우스터(106)가 진공압을 공급받을 수 있도록 연결되어 있다.In addition, the surge tank is connected to the brake booster 106 to receive a vacuum pressure.

이에 따라 엔진의 구동시에 형성되는 진공이 상기 서어지탱크에 저장되고, 이 서어지탱크의 진공압은 진공탱크로 공급되어 저장되며, 4륜구동시에는 상기 진공탱크의 진공압이 프리 휠 허브로 공급되어 전륜을 동력전달장치와 연결시키게 되어 있는 한편, 상기 서어지탱크의 진공압으로 브레이크 부우스터가 작동되어 운전자의 페달답력을 배력하여주게 되어 있다.Accordingly, the vacuum formed when the engine is driven is stored in the surge tank, and the vacuum pressure of the surge tank is supplied to and stored in the vacuum tank, and in four-wheel drive, the vacuum pressure of the vacuum tank is supplied to the free wheel hub. As a result, the front wheel is connected to the power transmission device, while the brake booster is operated by the vacuum pressure of the surge tank to increase the driver's pedaling power.

그런데 상기와 같은 종래의 구조에서 상기 공급호스나 연결호스가 원하지 않게 파손되면, 파손된 부위를 통해 대기가 유입됨과 더불어 이 대기는 상기 서어지탱크까지 공급되어, 브레이크 부우스터를 원만하게 작동시킬 수 없게 됨으로써, 대형 교통사고를 유발시킬 위험이 있었다.However, when the supply hose or the connection hose is undesirably damaged in the conventional structure as described above, the atmosphere is introduced through the damaged portion and the atmosphere is supplied to the surge tank, so that the brake booster can be operated smoothly. By being absent, there was a risk of causing a major traffic accident.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 진공탱크와 프리 휠 허브를 연결시키는 공급호스나 진공탱크와 서어지 탱크를 연결시키는 연결호스가 파손될 경우에 서어지탱크가 대기가 유입되지 않도록 차단하여 줌으로써 브레이크 부우스터가 제기능을 수행할 수 있도록 하여 교통사고의 위험을 줄여줄 수 있도록 된 4륜구동차량의 브레이크 안전장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, so that the surge tank does not enter the atmosphere when the supply hose connecting the vacuum tank and the free wheel hub or the connection hose connecting the vacuum tank and the surge tank is damaged. The purpose of the present invention is to provide a brake safety device for a four-wheel drive vehicle that can reduce the risk of a traffic accident by allowing the brake booster to function properly by blocking it.

상기한 바의 목적을 달성하기 위한 본 발명은, 서어지탱크에 연결호스를 매개로 진공탱크가 연결되고, 상기 진공탱크에는 프리 휠 허브로 진공을 공급하기 위해 공급호스가 연결되며, 이 공급호스에는 스위치 조작에 따라 제어전류를 공급받아 작동되면서 상기 공급호스를 개폐시키는 솔레노이드밸브가 설치되고, 상기 서어지탱크에는 브레이크 부우스터가 진공압을 공급받을 수 있도록 연결된 4륜구동차량의 진공장치에 있어서, 상기 서어지탱크쪽 연결호스에 서어지탱크와 진공탱크에 각각 연통되는 연결구멍을 가진 밸브바디가 설치되고, 이 밸브바디에는 상기 연결구멍을 폐쇄시키는 쪽으로 힘을 받도록 플러그가 스프링을 매개로 탄력적으로 지지되며, 상기 플러그는 서어지탱크의 진공압을 받도록 서어지탱크와 연결된 것을 특징으로 한다.The present invention for achieving the above object, the vacuum tank is connected to the surge tank via a connection hose, the vacuum tank is connected to the supply hose for supplying a vacuum to the free wheel hub, the supply hose In the solenoid valve for opening and closing the supply hose while operating by receiving a control current in accordance with the switch operation, the surge tank in the vacuum device of the four-wheel drive vehicle connected to the brake booster to receive a vacuum pressure, A valve body having a connection hole communicating with a surge tank and a vacuum tank, respectively, is installed in the surge tank side connecting hose, and the valve body is elastically connected via a spring so as to receive a force toward closing the connection hole. It is supported, the plug is characterized in that connected to the surge tank to receive the vacuum pressure of the surge tank.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 브레이크 안전장치가 설치된 진공호스라인의 개략적인 구성도인 바, 즉 서어지탱크(1)에 연결호스(2)를 매개로 진공탱크(3)가 연결되어 있고, 상기 진공탱크에는 프리 휠 허브로 진공을 공급하기 위해 공급호스(4)가 연결되어 있으며, 이 공급호스에는 스위치 조작에 따라 제어전류를 공급받아 작동되면서 상기 공급호스를 개폐시키는 솔레노이드밸브(5)가 설치되어 있다.2 is a schematic configuration diagram of a vacuum hose line equipped with a brake safety device according to the present invention, that is, a vacuum tank 3 is connected to a surge tank 1 via a connecting hose 2. A supply hose 4 is connected to the vacuum tank to supply a vacuum to the free wheel hub, and a solenoid valve 5 is installed in the supply hose to open and close the supply hose while being operated by a control current according to a switch operation. It is.

또 상기 서어지탱크에는 브레이크 부우스터(6)가 진공압을 공급받을 수 있도록 연결되어 있고, 상기 서어지탱크쪽 연결호스에 서어지탱크와 진공탱크에 각각 연통되는 연결구멍(7)을 가진 밸브바디(8)가 설치되고, 이 밸브바디에는 상기 연결구멍을 폐쇄시키는 쪽으로 힘을 받도록 플러그(9)가 스프링(10)을 매개로 탄력적으로 지지되며, 상기 플러그는 서어지탱크의 진공압을 받도록 분지호스(11)를 매개로 상기 연결호스에 연결된 구조로 되어 있다.In addition, the surge booster 6 is connected to the surge tank so as to receive a vacuum pressure, and a valve having a connection hole 7 connected to the surge tank and the vacuum tank, respectively, to the surge tank side connection hose. A body 8 is installed, the valve body is elastically supported by the spring 10 so that the valve body receives a force toward closing the connection hole, and the plug receives the vacuum pressure of the surge tank. The branch hose 11 is connected to the connection hose.

여기서 상기 밸브바디는 연결호스에 장착하지 않고 서어지탱크의 출구측에 직접작착하여도 무방하고, 상기 분지호스를 서어지탱크에 직접 연결시키도 된다.The valve body may be mounted directly on the outlet side of the surge tank without being mounted on the connection hose, and the branch hose may be directly connected to the surge tank.

이에 따라 서어지탱크에 정상적인 진공압이 형성된 경우에는 서어지탱크의 진공압이 상기 분지호스를 통해 플러그에 가해져서 상기 밸브바디의 연결구멍을 개방시켜주게 되므로, 서어지탱크의 진공압이 진공탱크로 공급되어 프리 휠 허브의 연결장치를 작동시킬 수 있게 되고, 또 서어지탱크의 진공압으로 브레이크 부우스터를 작동시킬 수 있게 된다.Accordingly, when a normal vacuum pressure is formed in the surge tank, the vacuum pressure of the surge tank is applied to the plug through the branch hose to open the connection hole of the valve body, so that the vacuum pressure of the surge tank is It is possible to operate the connection device of the freewheel hub and to operate the brake booster by the vacuum pressure of the surge tank.

그런데 상기 연결호스측이나 공급호스측이 파손되어 대기와 연통되게 되면, 파손된 부위를 통해 대기가 유입되게 되고, 이로 인해 상기 플러그에는 진공압이작용하지 않게 됨에 따라 플러그는 스프링에 의해 밀려져서 연결구멍을 막아주게 되므로, 진공탱크와 서어지탱크가 분리되게 되며, 이에 따라 최소한 브레이크 부으스터는 작동시킬 수 있게 되므로, 교통사고를 예방할 수 있게 되는 것이다.However, when the connection hose side or the supply hose side is damaged and communicates with the atmosphere, the atmosphere is introduced through the damaged portion, and as a result, the plug is pushed by the spring as the vacuum pressure does not act on the plug. Since the hole is blocked, the vacuum tank and the surge tank are separated, so that at least the brake booster can be operated, thereby preventing a traffic accident.

이상 설명한 바와 같이 본 발명에 따른 4륜구동차량의 브레이크 안전장치에 의하면, 진공공급라인에 파손이 유발되어 대기가 유입되어도 서어지탱크는 밸브에 의해 차단됨으로써 서어지탱크의 진공은 그대로 유지될 수 있게 되므로, 최소한 브레이크 부우스터는 원활하게 작동시켜 교통사고를 예방할 수 있는 효과가 있다.As described above, according to the brake safety device of the four-wheel drive vehicle according to the present invention, even if air is introduced due to damage to the vacuum supply line, the surge tank is blocked by the valve so that the vacuum of the surge tank can be maintained as it is. At the very least, the brake booster works well to prevent traffic accidents.
