Description

자동차 주차브레이크Car parking brake

본 발명은 자동차의 공압브레이크장치에 관한 것으로서, 더욱 상세하게는 대형 차량에 있어서 주차시 제동력을 증가시켜 보다 안전하게 차량을 주차시키는 자동차 주차브레이크에 관한 것이다.The present invention relates to a pneumatic brake device for a vehicle, and more particularly to a vehicle parking brake for parking a vehicle more safely by increasing the braking force during parking in a large vehicle.

도 1은 종래 공압브레이크장치를 나타내는 블록도이다.1 is a block diagram showing a conventional pneumatic brake device.

공압브레이크장치는 운전자가 브레이크페달을 밟으면 브레이크밸브(1)가 개방되어 에어탱크(2)의 압축공기가 릴레이밸브(3)로 전달된다. 릴레이밸브(3)는 브레이크밸브(1)로 부터의 공압에 의해서 온되어 에어탱크(2)의 공압을 마스타실린더(4)로 전달하고 마스타실린더(4)에서 각 브레이크시스템으로 공압을 전달하도록 되어 있다.In the pneumatic brake device, when the driver presses the brake pedal, the brake valve 1 is opened and the compressed air of the air tank 2 is transferred to the relay valve 3. The relay valve 3 is turned on by the pneumatic pressure from the brake valve 1 to transfer the pneumatic pressure of the air tank 2 to the master cylinder 4 and to transfer the pneumatic pressure from the master cylinder 4 to each brake system. have.

한편, 대부분의 자동차에는 주차시 제동력을 가하는 주차브레이크장치가 구비되어 있다. 종래의 주차브레이크는 주차브레이크핸들을 잡아 당겨 케이블의 당김력에 의하여 제동력을 가하게 되어 있다. 그리고 주차브레이크작용시에는 케이블이 당겨질 때 도1 에 도시된 바와 같이 주차브레이크스위치(5)를 온시켜 주차브레이크램프(6)를 점등하게 하고 있다.On the other hand, most cars are equipped with a parking brake device that applies a braking force when parking. Conventional parking brake is to apply the braking force by the pulling force of the cable by pulling the parking brake handle. In the parking brake operation, when the cable is pulled, the parking brake switch 5 is turned on as shown in FIG. 1 to turn on the parking brake lamp 6.

상기와 같은 주차브레이크시스템은 케이블의 당김력에 의해서만 제동력이 발생하기 때문에 그 제동력이 매우 약하다, 따라서 대형차에 있어서 경사진 곳에 주차할 때에는 주차브레이크가 풀리는 위험한 상황이 발생할 우려가 대단히 높다.Parking brake system as described above is very weak because the braking force is generated only by the pulling force of the cable, therefore, there is a high risk that the parking brake is released when parking inclined place in a large car.

본 발명은 전술한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 주차시, 특히 경사진 곳에 주차할 때 제동력을 크게 하여 안전사고를 방지하는 자동차 주차브레이크를 제공하는 데에 그 목적이 있다.The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide an automobile parking brake that prevents a safety accident by increasing the braking force during parking, especially when parking in an inclined place.

상기 목적을 달성하기 위한 본 발명의 자동차 주차브레이크는 주차브레이크스위치로 부터의 전원에 의해서 개방되어 에어탱크의 공압을 유출할수 있도록 된 솔레노이드밸브, 상기 솔레노이드밸브 또는 브레이크밸브로 부터의 제어압을 선택하여 출력하는 듀얼첵크밸브, 그리고 상기 듀얼첵크밸브로 부터 제어압을 받고 개방되어 상기 에어탱크의 공압을 마스타실린더로 공급하는 릴레이밸브를 포함하는 것을 특징으로 한다.The vehicle parking brake of the present invention for achieving the above object is selected by the control pressure from the solenoid valve, the solenoid valve or the brake valve which is opened by the power from the parking brake switch to allow the pneumatic pressure of the air tank to flow out. And a relay valve for outputting a dual check valve, and a relay valve receiving the control pressure from the dual check valve to open the air supply of the air tank to the master cylinder.

도2 는 본 발명의 자동차 주차브레이크를 포함하는 공압브레이크장치를 대략적으로 나타내는 구성도이다.Figure 2 is a schematic diagram showing a pneumatic brake device including a vehicle parking brake of the present invention.

도시된 바와 같이 본 발명의 자동차 주차브레이크는 주차브레이크스위치(5)로 부터의 전원에 의해서 개방되어 에어탱크(2)의 공압을 유출할수 있도록 된 솔레노이드밸브(7), 상기 솔레노이드밸브(7) 또는 브레이크밸브(1)로 부터의 제어압을 선택하여 출력하는 듀얼첵크밸브(8), 그리고 상기 듀얼첵크밸브(8)로 부터 제어압을 받고 개방되어 상기 에어탱크(2)의 공압을 마스타실린더(4)로 공급하는 릴레이밸브(3)를 포함하고 있다.As shown, the vehicle parking brake of the present invention is open by the power from the parking brake switch (5), the solenoid valve (7), the solenoid valve (7) or to allow the air pressure of the air tank (2) to flow out The dual check valve 8 selects and outputs the control pressure from the brake valve 1 and receives the control pressure from the dual check valve 8 to open the master cylinder. 4) relay valve (3) for supplying.

상기 주차브레이크스위치(5)는 종래와 같이 주차브레이크핸들을 잡아당기면 온되도록 되어 있다.The parking brake switch 5 is turned on by pulling the parking brake handle as in the prior art.

상기와 같이 구성된 본 발명의 자동차 주차브레이크는 다음과 같이 작용한다.Car parking brake of the present invention configured as described above acts as follows.

통상의 차량주행중 운전자가 브레이크페달을 밟으면 브레이크밸브(1)가 개방되어 에어탱크(2)의 압축공기가 듀얼첵크밸브(8)로 전달되고 듀얼첵크밸브(8)는 브레이크밸브(1)로 부터의 제어압을 릴레이밸브(3)로 전달한다. 릴레이밸브(3)는 듀얼첵크밸브(1)로 부터의 공압에 의해서 온되어 에어탱크(2)의 공압을 마스타실린더(4)로 전달하고 마스타실린더(4)에서 각 브레이크시스템으로 공압을 전달한다.When the driver presses the brake pedal during normal vehicle driving, the brake valve 1 is opened so that the compressed air of the air tank 2 is transferred to the dual check valve 8 and the dual check valve 8 is discharged from the brake valve 1. Control pressure is transmitted to the relay valve (3). The relay valve 3 is turned on by the pneumatic pressure from the dual check valve 1 to transfer the pneumatic pressure of the air tank 2 to the master cylinder 4 and to transfer the pneumatic pressure from the master cylinder 4 to each brake system. .

다음에 주차시 주차브레이크핸들을 잡아 당기면 주차브레이크스위치(5)가 온되어 주차브레이크램프(6)가 점등되면서 솔레노이드밸브(7)에 전원을 공급한다. 솔레이노이드밸브(7)가 개방되면 주차하도록 되어 있다.Next, when the parking brake handle is pulled during parking, the parking brake switch 5 is turned on, and the parking brake lamp 6 is turned on to supply power to the solenoid valve 7. When the solenoid valve 7 is opened, it is parked.

히타장치를 온시키면 에어탱크(2)의 압축공기가 듀얼첵크밸브(8)로 전달되고 듀얼첵크밸브(8)는 솔레노이드밸브(7)로 부터의 제어압을 릴레이밸브(3)로 전달한다. 릴레이밸브(3)는 듀얼첵크밸브(1)로 부터의 공압에 의해서 온되어 에어탱크(2)의 공압을 마스타실린더(4)로 전달하고 마스타실린더(4)에서 각 브레이크시스템으로 공압을 전달한다.When the heater is turned on, the compressed air of the air tank 2 is transferred to the dual check valve 8, and the dual check valve 8 transmits the control pressure from the solenoid valve 7 to the relay valve 3. The relay valve 3 is turned on by the pneumatic pressure from the dual check valve 1 to transfer the pneumatic pressure of the air tank 2 to the master cylinder 4 and to transfer the pneumatic pressure from the master cylinder 4 to each brake system. .

따라서 주차시에도 통상의 브레이크페달을 밟을 때와 마찬가지로 큰 제동력이 가핸진다.Therefore, even when parking, a large braking force is applied as in a normal brake pedal.

전술한 바와 같이 본 발명의 자동차 주차브레이크는 주차시에도 통상의 브레이크페달을 밟을 때와 마찬가지의 큰 제동력을 가하므로 경사진 곳에 주차하여도 안전하게 주차되는 효과를 발휘한다.As described above, the vehicle parking brake of the present invention exerts the same large braking force as when stepping on a normal brake pedal even when parked, so that the vehicle is safely parked even when parked on an inclined place.

본 발명은 기재된 실시예에만 한정되는 것이 아니고, 본 발명의 사상 및 범위내에서 다양하게 수정 또는 변형을 할수 있음은 이 기술분야에서 통상의 지식을 가진자에는 자명하다. 따라서 그러한 수정예 또는 변형예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.It is apparent to those skilled in the art that the present invention is not limited only to the embodiments described, and that various modifications or changes can be made within the spirit and scope of the present invention.
