Description
본 발명은 차량의 제동장치에 관한 것으로, 특히 주차중 주차브레이크 장치가 해제 되었을 때 작동하도록 하므로써 안전사고를 예방할 수 있도록 된 주차브레이크 보조장치에 관한 것이다.The present invention relates to a braking device for a vehicle, and more particularly to a parking brake assistance device that can prevent a safety accident by operating when the parking brake device is released during parking.
제동장치는 차량 주행시 감속 또는 순간정지 시킴과 동시에 주차 상태를 안전하게 유지하기 위해 사용되는 것으로 로드나 와이어를 이용하는 기계식과 유압을 이용하는 유압식이 있다.The braking device is used to decelerate or momentarily stop the vehicle while driving, and to maintain the parking state safely. There are a mechanical system using a rod or wire and a hydraulic system using hydraulic pressure.
기계식 주차브레이크에는 상용차에서 사용되는 크로스 풀 타입(cross full type)과 승용차에 주로 사용되는 포워드 풀 타입(forward pull type)이 있는데, 이 포워드 풀 타입은 주차브레이크 레버로 케이블을 당겨 좌측과 우측 휠을 구속시키는 방식이다.Mechanical parking brakes include a cross full type used in commercial vehicles and a forward pull type mainly used in passenger cars. This forward pull type uses the parking brake lever to pull the cable to the left and right wheels. It is a way of restraint.
도 2에는 종래 사용되고 있는 포워드 풀 타입의 주차브레이크가 도시되어 있는 바, 이는 차체에 고정된 브라켓트(1)를 매개로 장착된 브레이크레버(2)와, 이 브레이크레버(2)에 연결된 케이블(3), 좌측휠(4) 및 우측휠(5)과 연결된 케이블(6,7), 이들 케이블(3,6,7)들을 연결시키는 케이블 이퀄라이저 조인트(8)를 갖추고 있다.FIG. 2 shows a parking pull of a forward pull type conventionally used, which includes a brake lever 2 mounted via a bracket 1 fixed to a vehicle body, and a cable 3 connected to the brake lever 2. ), Cables 6,7 connected to the left wheel 4 and the right wheel 5, and a cable equalizer joint 8 connecting these cables 3,6,7.
따라서, 상기 브레이크레버(2)를 당기면 케이블 이퀄라이저 조인트(8)를 매개로 케이블(6,7)이 브레이크레버(2) 측으로 당겨짐과 동시에 연쇄적으로 좌측휠(4) 및 우측휠(5)이 구속되도록 되어 있다.Accordingly, when the brake lever 2 is pulled, the cables 6 and 7 are pulled toward the brake lever 2 via the cable equalizer joint 8 and the left wheel 4 and the right wheel 5 are connected in series. It is to be restrained.
그러나, 이러한 구조로 된 주차브레이크 장치(9)는 차체에 예기치 않은 충격이 가해지거나 기계적인 결함으로 인해 브레이크레버(2)가 릴리즈 되면 주차브레이크 장치(9)의 구속력이 저하되어 대형사고로 이어지는 경우가 종종 발생한다.However, when the parking brake device 9 having such a structure is released when the brake lever 2 is released due to an unexpected impact on the vehicle body or a mechanical defect, the binding force of the parking brake device 9 is reduced, leading to a large accident. Often happens.
또한, 이러한 문제를 방지하기 위해 여러가지 보조장치를 결합하므로써 릴리즈 현상을 최대한 방지하도록 된 것이 개발되었는데 이는 도 3에 개략적으로 도시된 것과 같이 풋브레이크에 연결하여 사용하도록 된 것이다.In addition, in order to prevent such a problem was developed to prevent the release phenomenon as much as possible by combining various auxiliary devices, which is to be used to connect to the foot brake as shown schematically in FIG.
즉, 전원(10)과, 이 전원(10)에 연결된 파킹레버스위치(11), 이 파킹레버스위치(11)의 한쪽 접점에 연결된 스피드메터스위치(12) 및, 이 스피드메터스위치(12)의 다른쪽 접점과 연결되고 브레이크제동부(13)를 작동시키도록 된 액츄에이터(14)를 갖추고 있다.That is, the power supply 10, the parking lever switch 11 connected to the power supply 10, the speed meter switch 12 connected to one contact of the parking lever switch 11, and the speed meter switch 12 An actuator 14 is connected to the other contact and adapted to actuate the brake brake 13.
그리고, 상기 스피드메터스위치(12)는 차량이 정지된 상태에서는 접촉단자(15)와 접촉자(16)가 떨어져 스위치가 오프되고, 차량이 움직이는 상태에서는 접촉단자(15)와 접촉자(16)가 붙어 스위치가 온되도록 구성되어 있다.In addition, the speed meter switch 12 is switched off when the contact terminal 15 and the contactor 16 are separated while the vehicle is stopped, and the contact terminal 15 and the contactor 16 are attached when the vehicle is in a moving state. The switch is configured to be on.
따라서, 운전자가 차량을 주차시키기 위해 주차브레이크레버를 잡아당긴 다음 운전석에서 내렸을 때, 외부충격이나 기타 다른 요인으로 자동차가 움직이면 상기 스피드메터스위치(12)의 접촉단자(15)와 접촉자(16)가 접지되어 스위치가 온되고, 이에 따라 전원이 통전되어 액츄에이터(14)를 작동시켜 브레이크제동부(13)를 동작시킴에 따라 자동차가 정지되게 된다.Therefore, when the driver pulls the parking brake lever to park the vehicle and then gets out of the driver's seat, if the vehicle moves due to external shock or other factors, the contact terminal 15 and the contactor 16 of the speed meter switch 12 The ground is switched on and thus the power is energized to operate the actuator 14 to operate the brake braking unit 13 so that the vehicle is stopped.
또한, 운전자가 브레이크레버를 해제시키면 전원이 차단되어 액츄에이터(14)로 전원이 공급되지 않게 되므로 정상적인 상태로 되돌아 가게 된다.In addition, when the driver releases the brake lever, power is cut off and power is not supplied to the actuator 14, thereby returning to the normal state.
그러나, 이와 같은 구조로 된 주차브레이크장치(17) 역시 스위치가 수시로 온 오프되기 때문에 전기적인 결함이 발생할 가능성이 있고, 이러한 결함으로 인해 필요시 장치 전체가 동작되지 않을 수 있다는 단점이 있다.However, the parking brake device 17 having such a structure also has the disadvantage that an electrical defect may occur because the switch is frequently turned on and off, and the entire apparatus may not be operated when necessary due to such a defect.
이에 본 발명은 상기와 같은 제반 단점을 해결하기 위한 것으로, 가변저항기를 사용하여 액츄에이터의 동작을 제어 하므로써 록킹이 해제되었을 때 신속하게 휠을 다시 구속할 수 있도록 하여 안전사고가 발생하는 것을 방지할 수 있도록 된 주차브레이크 보조장치를 제공함에 그 목적이 있다.Accordingly, the present invention is to solve the above disadvantages, by controlling the operation of the actuator using a variable resistor to be able to restrain the wheel quickly when the lock is released to prevent the occurrence of a safety accident. It is an object of the present invention to provide a parking brake assistance device.
상기와 같은 목적을 달성하기 위한 본 발명은, 브레이크레버와 연결된 케이블에 가변저항기가 설치되고, 이 가변저항기는 전원과 연결된 파킹레버스위치의 한쪽 접점과 연결되어 상기 가변저항기에서 읽어들인 저항값에 따라 선택적으로 액츄에이터를 동작시키도록 구성되어 있다.According to the present invention for achieving the above object, a variable resistor is installed in the cable connected to the brake lever, the variable resistor is connected to one contact of the parking lever switch connected to the power source in accordance with the resistance value read from the variable resistor Optionally configured to operate the actuator.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 주차브레이크 장치를 개략적으로 나타낸 구성도로써 종래구조를 도시한 도 3 및 도 4와 동일 부위에는 동일 참조부호가 도시되어 있는 바, 본 발명은 도면에 도시된 것과 같이, 브레이크레버(2)에 케이블(3)이 연결되고, 후륜을 이루는 좌측휠(4)과 우측휠(5)에 각각 케이블(6,7)이 연결되며 이들 케이블(3,6,7)들은 케이블 이퀄라이저 조인트(8)와 연결되어 있다.1 is a schematic view showing a parking brake apparatus according to the present invention, the same reference numerals are shown in the same parts as those of FIGS. The cable 3 is connected to the brake lever 2, and the cables 6 and 7 are connected to the left wheel 4 and the right wheel 5 respectively forming the rear wheels. It is connected to the equalizer joint (8).
그리고, 전원(10)과 파킹레버스위치(11)가 전기적으로 연결되고, 브레이크제동부(13)를 동작시키는 액츄에이터(14)와 상기 파킹레버스위치(11) 간에는 가변저항기(20)가 설치되어 있다.The power supply 10 and the parking lever switch 11 are electrically connected to each other, and a variable resistor 20 is provided between the actuator 14 for operating the brake braking unit 13 and the parking lever switch 11. .
본 장치는 브레이크레버(2)를 잡아당겨 록크 시키면 파킹레버스위치(11)가 온 상태로 되고, 시동장치를 오프시켰을 때 통전 상태가 된다. 그리고, 케이블(3)에 부착된 가변저항기(20)에서 일정이상의 저항이 측정되면 액츄에이터(14)가 동작되지 않게 되고 케이블(3)의 장력이 이완되었거나 파킹레버스위치(11)가 오프 되었을 때에는 액츄에이터(14)를 동작시켜 브레이크제동부(13)를 작동시키게 됨에 따라 풋브레이크를 작동하여 자동차를 정지시키도록 되어 있다.This device pulls and locks the brake lever 2, and the parking lever switch 11 is turned on. When the starter is turned off, the device is energized. When the resistance of the predetermined resistance is measured by the variable resistor 20 attached to the cable 3, the actuator 14 is not operated. When the tension of the cable 3 is relaxed or the parking lever switch 11 is turned off, the actuator As the brake brake unit 13 is operated by operating 14, the foot brake is operated to stop the vehicle.
즉, 차량의 구속상태가 릴리즈되어 휠이 회전하게 되면 이 휠을 구속하고 있던 케이블(3)이 릴리즈되는 것이므로 가변저항기(20)에서 측정되는 저항값이 변하게 되고, 이와 같이 최초선정된 저항값과 비교하여 차이가 발생하면 액츄에이터(14)를 동작시키게 되는 것이다.In other words, when the wheel is released and the wheel is rotated, the cable 3 that restrains the wheel is released, and thus the resistance value measured by the variable resistor 20 is changed. If a difference occurs in comparison, the actuator 14 is operated.
그리고, 파킹브레이크를 해제하거나 시동키를 온 시키면 보조브레이크장치가 해제되도록 되어 있다.Then, when the parking brake is released or the ignition key is turned on, the auxiliary brake device is released.
이상 설명한 바와 같이 본 발명에 따르면 가변저항기를 사용하여 액츄에이터의 동작을 제어 하므로써 록킹이 해제되었을 경우 신속하게 브레이크제동부를 동작시켜 휠을 다시 구속하므로써 안전사고가 발생하는 것을 미연에 방지할 수 있는 효과가 있다.As described above, according to the present invention, when the locking is released by controlling the operation of the actuator by using a variable resistor, the brake braking unit is quickly operated to restrain the wheel again, thereby preventing the occurrence of a safety accident. There is.
