Description

안전 브레이크 장치Safety brake device

본 발명은 차량의 브레이크에 관한 것으로서, 특히 언덕길에서의 정지시 브레이크의 압력을 일정하게 유지하여 차량이 정지상태에서 뒤로 밀리지 않고 바로 출발가능하도록 한 안전 브레이크 장치(Safety Brake Device)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake of a vehicle, and more particularly, to a safety brake device that maintains a constant pressure of a brake at a stop on a hill so that the vehicle can start immediately without being pushed back from a stopped state.

일반적으로 언덕길에서 운전자가 차량의 브레이크 페달을 밟으면, 차량은 언덕길의 일정위치에서 정지하게 되는 것으로, 이때, 운전자는 차량의 주차브레이크를 잡아당기므로서, 언덕길에서의 차량 밀림현상을 방지할수 있도록 하였으며, 차량을 출발시킬 경우에는 운전자는 클러치 페달을 밟으면서 변속레버를 조작하였다.In general, when the driver presses the vehicle's brake pedal on the hill, the vehicle stops at a certain position on the hill. At this time, the driver pulls the parking brake of the vehicle to prevent the vehicle from falling on the hill. In the case of starting the vehicle, the driver operated the shift lever while depressing the clutch pedal.

그러나, 상기 설명된 선행기술에 의한 브레이크를 사용할 때, 운전자가 차량을 다시 출발시키고자 주차브레이크를 풀고 클러치 페달을 밟으면서 변속레버를 조작하면, 상기 주차브레이크의 풀림현상에 의해 차량이 뒤로 밀리게 되고, 이를 방지하기 위해 운전자는 차량의 브레이크 페달에 일정압력을 주도록 힘을 가해야 하므로서, 운전자의 다리에는 무리한 힘이 들어감은 물론 브레이크의 라이닝(Lining)이 과다하게 마모되거나 또는 언덕길에서의 출발과 정지가 제대로 제어되지 못하는등 차량의 안정성이 저하되는 문제점이 있었다.However, when using the brake according to the prior art described above, if the driver operates the shift lever while releasing the parking brake and depressing the clutch pedal to start the vehicle again, the vehicle is pushed backward by the release phenomenon of the parking brake. In order to prevent this, the driver must apply a force to apply a constant pressure to the brake pedal of the vehicle, so that the driver's legs are not overwhelmed and the lining of the brake is excessively worn or the departure from the hillside There was a problem that the stability of the vehicle is lowered, such as the stop is not properly controlled.

따라서, 본 발명은 이와같은 문제점을 해결하기 위해 언덕길에서의 정지시 브레이크의 압력을 일정하게 유지할수 있도록 안전 브레이크 시스템을 구축하므로서, 차량이 정지상태에서 출발시 뒤로 밀리지 않고 바로 출발가능하도록 하여 운전자의 다리에 무리한 힘이 들어가는 것을 방지함은 물론 브레이크의 라이닝이 과다하게 마모되는 것을 방지하여 언덕길에서의 출발과 정지가 제대로 제어가능하도록 하는등 차량의 안정성을 향상시키고자 하는데 그 목적이 있는 것이다.Therefore, in order to solve this problem, the present invention builds a safety brake system that can maintain a constant pressure of the brake when stopping on a hill road, so that the vehicle can be started immediately without being pushed back when the vehicle is stopped. The purpose is to improve the stability of the vehicle by preventing excessive force from entering the legs and preventing excessive wear of the lining of the brakes so that start and stop on hills can be controlled properly.

이하 첨부된 도 1를 참조하여 본 발명의 바람직한 실시예를 상술한다.Hereinafter, with reference to the accompanying Figure 1 will be described a preferred embodiment of the present invention.

도 1은 본 발명 안전 브레이크 장치의 구조를 보인 블록구성도이다.1 is a block diagram showing the structure of the safety brake device of the present invention.

도 1에 도시된 바와같이, 차량의 밀림현상을 방지할수 있도록 전자제어 유니트(1)에서는 리저브 탱크(2)에 저장된 일정압을 마스터 실린더(3) 및 제어밸브(4)를 통해 차량의 브레이크에 공급시키도록 클러치 및 브레이크와 변속레버의 작동상태에 따라 제어동작을 하게 되고, 상기 전자제어 유니트(1)의 제어동작에 따라 작동스위치(SW1)에서는 온/오프 스위칭 동작하게 되며, 상기 작동스위치(SW1)의 온/오프 스위칭 동작에 따라 솔레노이드 밸브(5)에서는 구동하여 제어밸브(4)에 의해 공급흐름이 제어된 일정압을 일정하게 차량의 브레이크 튜브(R/H, L/H)로 공급시켜 차량이 언덕길에서 출발시 밀림현상을 방지하는 구조이다.As shown in FIG. 1, in the electronic control unit 1, the constant pressure stored in the reserve tank 2 is applied to the brake of the vehicle through the master cylinder 3 and the control valve 4 so as to prevent the vehicle from being pushed. The control operation is performed according to the operation state of the clutch, brake and shift lever so as to be supplied, and the on / off switching operation is performed at the operation switch SW1 according to the control operation of the electronic control unit 1. In accordance with the on / off switching operation of SW1), the solenoid valve 5 is driven to constantly supply a constant pressure controlled by the control valve 4 to the brake tubes R / H and L / H of the vehicle. It is a structure to prevent the jungle phenomenon when the vehicle starts from the hill.

상기와 같은 일실시예의 구성에 따라, 운전자가 차량을 언덕길에 임의적으로 정차시킨 후, 다시 출발하고자 클러치 및 브레이크 페달을 밟으면, 상기 클러치 및 브레이크 페달의 동작에 따라 전자제어 유니트(1)에서는 차량이 뒤로 밀리지 않도록 제어동작을 하게 된다. 즉, 상기 전자제어 유니트(1)의 제어동작에 따라 작동스위치(SW1)에서 온 스위칭 동작을 하게 되고, 상기 작동스위치(SW1)의 온 스위칭 동작에 따라 솔레노이드 밸브(5)는 열림상태의 구동을 하게 되는 것이다.According to the configuration of the embodiment as described above, if the driver arbitrarily stops the vehicle on the hill, and then press the clutch and brake pedal to start again, the electronic control unit 1 in accordance with the operation of the clutch and brake pedal The control operation is performed so as not to be pushed back. That is, the on-switching operation of the operation switch SW1 is performed according to the control operation of the electronic control unit 1, and the solenoid valve 5 is driven in the open state in accordance with the on-switching operation of the operation switch SW1. Will be done.

이때, 마스터 실린더(3)의 구동 및 제어밸브(4)의 공급흐름 제어동작에 따라 리저브 탱크(2)에서의 일정압이 상기 열림구동한 솔레노이드 밸브(5)를 통해 차량의 브레이크 튜브에 공급되므로서, 브레이크의 라이닝까지 상기 브레이크 튜브에는 일정압이 계속적으로 일정하게 공급되어 차량이 원활하게 출발가능하도록 언덕길에서의 차량 밀림현상을 방지시키게 되는 것이다.At this time, the constant pressure in the reservoir tank 2 is supplied to the brake tube of the vehicle through the open solenoid valve 5 according to the driving of the master cylinder 3 and the supply flow control operation of the control valve 4. In this case, the brake tube is continuously supplied with a constant pressure until the lining of the brake to prevent the vehicle from rolling on the hill so that the vehicle can start smoothly.

한편, 차량이 출발가능한 상태를 유지한 상태에서 운전자가 차량의 변속레버를 변속 1단으로 조작시킨 후, 클러치 페달을 놓으면, 상기 전자제어 유니트(1)에서는 작동스위치(SW1)의 스위칭 동작을 오프시키는 제어동작을 하게 되고, 상기 작동스위치(SW1)의 오프 스위칭 동작에 따라 솔레노이드 밸브(5)는 닫힘구동을 하게 되므로서, 마스터 실린더(3) 및 제어밸브(4)를 통해 차량의 브레이크 튜브로 일정하게 공급되던 리저브 탱크(2)의 일정압은 차단되는 것이다.On the other hand, when the driver operates the shift lever of the vehicle to the first gear shift while the vehicle remains in a startable state and releases the clutch pedal, the electronic control unit 1 turns off the switching operation of the operation switch SW1. The solenoid valve 5 is closed and driven according to the off-switching operation of the operation switch SW1, so that the brake tube of the vehicle is connected to the vehicle via the master cylinder 3 and the control valve 4. The constant pressure of the reserve tank 2 which was constantly supplied is cut off.

이상에서 설명한 바와같이 본 발명은 언덕길에서의 정지시 브레이크의 압력을 일정하게 유지할수 있도록 안전 브레이크 시스템을 구축하므로서, 차량이 정지상태에서 출발시 뒤로 밀리지 않고 바로 출발가능하도록 하여 운전자의 다리에 무리한 힘이 들어가는 것을 방지함은 물론 브레이크의 라이닝이 과다하게 마모되는 것을 방지하여 언덕길에서의 출발과 정지가 제대로 제어가능하도록 하는등 차량의 안정성을 향상시키는 효과가 있는 것이다.As described above, the present invention constructs a safety brake system to maintain a constant pressure of the brake when stopping on a hill road, so that the vehicle can be started immediately without being pushed back when the vehicle is stopped from being stopped. In addition to preventing this from entering, the lining of the brake is prevented from being excessively worn, so that the start and stop on the hill road can be controlled properly, thereby improving the stability of the vehicle.
