본 발명은 차량의 경사노면 출발시 미끄럼을 방지하는 파킹 브레이장치에 관한 것으로, 특히 언덕길에서 주, 정차를 행한 상태에서 출발한 경우 후방으로의 미끄럼을 방지하여 안전사고의 위험을 미연에 방지하도록 된 차량의 경사노면 출발시 미끄럼을 방지하는 파킹브레이크장치에 관한 것이다.The present invention relates to a parking braking device that prevents slipping at the start of the inclined road surface of the vehicle, in particular, to prevent the sliding of the rear to prevent the risk of safety accidents when starting from the state of the hill and stop The present invention relates to a parking brake device that prevents sliding at the start of the inclined road surface of a vehicle.

일반적으로 경사노면에 주,정차를 행함에 있어 수동변속차량의 경우에는 기어 변속레버 P위치로 조작하고, 파킹브레이크 레버를 당기며, 수동변속차량은 언덕길에서 기어변속레버를 전진위치로 변속하고 내리막길에서 후진위치로 변속한 다음 파킹브레이크 레버를 당기게 된다.In general, in the case of the main and stop on the inclined road, the manual geared vehicle is operated by the gear shift lever P position, the parking brake lever is pulled, and the manual geared vehicle shifts the gear shift lever to the forward position on the hill road and goes downhill. After shifting from the road to the reverse position, pull the parking brake lever.

그러나 경사노면의 기울기가 일정 각도 이상으로 형성되어 있을 경우 차량의 출발이 용이하지 아니하며, 이는 특히 초보 운전자들에게 매우 어려운 일이 아닐 수 없다.However, when the inclination of the inclined road surface is formed at a certain angle or more, starting of the vehicle is not easy, which is especially difficult for the novice drivers.

또한 능숙한 운전자라 하더라도 경사도가 크거나 동절기 빙판길 등 에서의 출발이 용이하지 않다.In addition, even a good driver is not easy to start from a slope or winter icy road.

본 발명의 목적은 경사노면에서의 출발을 용이하게 행할 수 있는 차량의 경사노면 출발시 미끄럼을 방지하는 파킹 브레이크 장치를 제공하기 위한 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide a parking brake device that prevents slipping at the start of an inclined road surface of a vehicle that can easily start on an inclined road surface.

본 발명은 상기의 목적을 달성하기 위하여 휠에 착탈되는 클러치 풀리를 구비하고, 클러치 풀리에 피스톤을 형성하여 유압실린더에 포함시키며, 또 유압실린더에 솔레노이드 밸브를 연결하고, 솔레이노 밸브에 유압펌프및 유압탱크를 연결하며, 아울러 E.C.U의 입,출력단에 스피드센서와 경사각 센서 및 유압펌프와 솔레노이드 밸브를 연결하며, 차속이 0이고 일정값 이상의 경사각을 가질 경우 E.C.U 로부터 제동출력을 발생시키는 것을 특징으로 갖는다.The present invention comprises a clutch pulley detachable to the wheel to achieve the above object, and forms a piston in the clutch pulley to be included in the hydraulic cylinder, and connecting the solenoid valve to the hydraulic cylinder, the hydraulic pump and the solenoid valve The hydraulic tank is connected, and the speed sensor, the inclination angle sensor, the hydraulic pump and the solenoid valve are connected to the input and output terminals of the ECU, and the braking output is generated from the ECU when the vehicle speed is 0 and has a predetermined inclination angle. .

이하, 본 발명의 구체적인 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

제1도는 본 발명 파킹브레이크 장치의 구성도이고, 제2도는 본 파킹 브레이크장치의 요부 측면도를 각기 나타낸 것이다.1 is a configuration diagram of the parking brake device of the present invention, and FIG. 2 is a side view of main parts of the parking brake device.

도면과 같이, 휠(10)의 내측에 착탈되는 클러치 풀리(20)가 구비되고, 클러치 풀리(20)에 브레이크 밴드(30)가 권취되면서 이 브레이크 밴드(30)의 입력단 및 출력단이 파킹브레이크 레버의 케이블 및 차체의 스프링(31)에 연결되어 있다.As shown in the drawing, a clutch pulley 20 detachably provided on the inside of the wheel 10 is provided, and the brake band 30 is wound around the clutch pulley 20 while the input and output ends of the brake band 30 are parked brake levers. The cable is connected to the spring 31 of the vehicle body.

클러치 풀리(20)의 내측에 피스톤(21)이 형성되면서 유압실린더(40)에 포함되어 있고, 유압실린더(40)의 양측 포트에 솔레노이드 밸브(50)가 연결되어 있다.The piston 21 is formed inside the clutch pulley 20 and included in the hydraulic cylinder 40, and the solenoid valve 50 is connected to both ports of the hydraulic cylinder 40.

또한 솔레노이드 밸브(50)는 유압펌프(60)와 유압탱크(70)에 연결되고, 이들 솔레노이드 밸브(50) 및 유압펌프(600)가 E.C.U(80)에 연결되어 있다.In addition, the solenoid valve 50 is connected to the hydraulic pump 60 and the hydraulic tank 70, these solenoid valve 50 and the hydraulic pump 600 is connected to the E.C.U (80).

아울러 E.C.U(80)의 입력단에는 스피드센서(90) 및 경사각 센서(100)가 연결되어 있다.In addition, the speed sensor 90 and the inclination angle sensor 100 are connected to an input terminal of the E.C.U 80.

따라서 차량의 주행이 정지되어 스피드센서(90)로부터 E.C.U(80)에 인가되는 신호값이0이고, 또한 차량의 주,정차 노면이 일정값 이상의 경사각을 가질 경우 그 경사각 센서(100)로부터의 측정신호가 E.C.U(80)에 인가되면서 E.C.U(80)는 솔레노이드 밸브(50)를 우측방향으로 작동시키고, 유압펌프(60)를 구동시킨다.Therefore, when the driving of the vehicle is stopped and the signal value applied from the speed sensor 90 to the ECU 80 is 0, and the main and stop road surface of the vehicle has an inclination angle of a predetermined value or more, the measurement from the inclination angle sensor 100 is performed. As the signal is applied to the ECU 80, the ECU 80 operates the solenoid valve 50 in the right direction and drives the hydraulic pump 60.

유압펌프(60)가 구동되면서 유압펌프(70)의 오일이 솔레노이드 밸브(50)를 통해 유압실린더(40)의 좌측에 공급되며, 이때 피스톤(21)이 전진하면서 클러치 풀리(20)을 전진시킨다.While the hydraulic pump 60 is driven, the oil of the hydraulic pump 70 is supplied to the left side of the hydraulic cylinder 40 through the solenoid valve 50. At this time, the piston 21 moves forward to advance the clutch pulley 20. .

클러치 풀리(20)가 휠(10)에 접촉,밀착되면서 휠(10)을 제동시키며, 이때 메인 브레이크 또는 파킹브레이크를 해제시키더라도 휠(10)의 급격한 밀림은 방지된다.The clutch pulley 20 brakes the wheel 10 while being in contact with and in close contact with the wheel 10. At this time, even if the main brake or the parking brake is released, the sudden push of the wheel 10 is prevented.

이후, 파킹브레이크 레버를 당기면 브레이크 밴드(30)가 당겨지면서 클러치 풀리(20)에 압착되어 클러치 풀리(20)의 회전을 방지하여 경사노면에서의 주,정차상태를 안정되게 유지한다.Thereafter, when the parking brake lever is pulled, the brake band 30 is pulled and squeezed to the clutch pulley 20 to prevent rotation of the clutch pulley 20 to maintain the main and stop state on the inclined road surface.

한편, 주,정차 상태에서 출발을 시도할 경우에는 파킹 브레이크 레버를 해제시키면 브레이크 밴드(30)가 클러치 풀리(20)로부터 풀리게 되는데, 여기서 클러치 풀리(20)와 휠(10)의 마찰,접촉에 의하여 미끄럼은 발생하지 아니하므로 이때 차량의 출발을 행할 수 있다.On the other hand, when attempting to start in the main and stop state, the brake band 30 is released from the clutch pulley 20 by releasing the parking brake lever, where the friction and contact between the clutch pulley 20 and the wheel 10 Since no sliding occurs, the vehicle can be started at this time.

또한 차량이 스타트되면서 스피드 센서(90)로부터 감지된 일정값 이상의 속도값이 E.C.U(80)에 인가되면, 이와 동시에 E.C.U(80)는 차량의 출발신호임을 인식하여 솔레이노 밸브(50)을 좌측방향으로 작동시키고, 또한 유압펌프(60)를 구동시켜 유압탱크(70)로부터의 오일을 유압실린더(40)의 우측에 공급한다.In addition, when the vehicle is started and a speed value greater than a predetermined value detected from the speed sensor 90 is applied to the ECU 80, the ECU 80 recognizes that the vehicle is a start signal and moves the solenoid valve 50 to the left. And the hydraulic pump 60 is driven to supply oil from the hydraulic tank 70 to the right side of the hydraulic cylinder 40.

이때 피스톤(21)이 좌측방향으로 이동하면서 그 클러치 풀리(20)를 휠(10)로부터 이격,분리시키고, 휠(10)의 제동상태가 완전히 해제되어 차량의 출발이 행하여 진다.At this time, while the piston 21 moves to the left direction, the clutch pulley 20 is separated and separated from the wheel 10, and the braking state of the wheel 10 is completely released to start the vehicle.

이상과 같이 본 발명은 휠에 착탈되는 클러치 풀리를 구비하고, 클러치 풀리에 피스톤을 형성하여 유압실린더에 포함시키며, 또 유압실린더에 솔레노이드 밸브를 연결하고, 솔레노이드 밸브에 유압펌프 및 유압탱크를 연결하며, 아울러 E.C.U의 입출력단에 스피드센서와 경사각 센서 및 유압펌프와 솔레노이드 밸브를 연결하며, 차속이 0이고 일정값 이상의 경사각을 가질 경우 E.C.U로부터 제동출력을 발생시킴으로써, 경사노면에서의 출발을 용이하게 행할 수 있는 것은 물론 미끄럼을 방지하여 안전사고를 미연에 예방하는 효과를 갖는다.As described above, the present invention includes a clutch pulley detachable to a wheel, forms a piston in the clutch pulley, and includes the hydraulic cylinder, and connects the solenoid valve to the hydraulic cylinder, and connects the hydraulic pump and the hydraulic tank to the solenoid valve. In addition, the speed sensor, the inclination angle sensor, the hydraulic pump, and the solenoid valve are connected to the input / output terminals of the ECU. When the vehicle speed is 0 and the inclination angle is higher than a predetermined value, the braking output is generated from the ECU, so that the start of the inclined surface can be easily performed. Of course, it has the effect of preventing slipping by preventing slipping.
