본 발명의 주차 브레이크 유격 조절장치는, 도 1에 도시된 바와같이, 차량을 운행시키는 운전자의 조작에 따라 구동되는 주차 브레이크 레버(1)와, 상기 주차 브레이크 레버(1) 의 구동에 따라 스위칭 동작하는 주차 브레이크 스위칭부(2)와, 주차 브레이크 레버(1)의 구동에 따라 일정유압을 발생시키는 유압 실린더 (3)와, 주차 브레이크 레버(1) 및 상기 유압 실린더(3)를 연결시킨 케이블(4)과, 유압 실린더(3)내에 장착되면서 상기 케이블(4)에 연결되어 주차 브레이크 레버(1)의 구동에 따라 직선왕복운동하는 피스톤 (5)과, 상기 피스톤(5)의 직선왕복운동에 따라 유압 실린더(3)내에서 발생되는 일정유압을 감지하는 유압센서(6)와, 주차 브레이크의 유격을 조절시키기 위해 상기 유압센서(6)에 의해 감지된 일정유압에 따라 유압실린더(3)내의 유압을 일정하게 유지시키도록 펌프 동작하는 펌프(7)와, 유압실린더(3)에서 회수되는 오일을 저장시키면서 상기 펌프(7) 의 펌프동작이 원활하게 이루어질 수 있도록 저장된 오일을 공급하는 리저브 탱크(8)와, 주차 브레이크 레버(1)의 구동에 따라 펌프(7)에 의해 유압실린더(3)로 공급되는 유압을 차단시키는 차단 밸브(9)로 구성된다.As shown in FIG. 1, the parking brake play control apparatus of the present invention has a parking brake lever 1 driven according to a driver's operation of driving a vehicle and a switching operation according to the driving of the parking brake lever 1. Parking brake switching unit 2, a hydraulic cylinder (3) for generating a constant hydraulic pressure in accordance with the drive of the parking brake lever (1), a cable connecting the parking brake lever (1) and the hydraulic cylinder (3) 4) and a piston (5) mounted in the hydraulic cylinder (3) and connected to the cable (4) and linearly reciprocating according to the driving of the parking brake lever (1), and the linear reciprocating motion of the piston (5). According to the hydraulic sensor 6 for detecting a constant hydraulic pressure generated in the hydraulic cylinder (3), and according to the constant pressure detected by the hydraulic sensor (6) to adjust the play of the parking brake in the hydraulic cylinder (3) To make the hydraulic constant A pump 7 operating the pump to maintain the pump, a reservoir tank 8 for supplying the stored oil so that the pump operation of the pump 7 can be performed smoothly while storing the oil recovered from the hydraulic cylinder 3, It consists of a shut-off valve 9 which cuts off the hydraulic pressure supplied to the hydraulic cylinder 3 by the pump 7 according to the drive of the parking brake lever 1.

여기서 미설명 부호 10은 브레이크와 연결되는 브레이크 구동케이블이고, 11은 펌프(7)를 통해 공급되는 오일을 유압실린더(3)로 공급하는 오일공급관, 12는 유압실린더(3)로 부터 회수되는 오일을 리저브 탱크(8)로 환원시키는 오일회수관이며, 13은 실린더(3) 선단에 설치되는 케이블 연결판을 각기 나타내고 있다.Here, reference numeral 10 is a brake drive cable connected to the brake, 11 is an oil supply pipe for supplying the oil supplied through the pump (7) to the hydraulic cylinder (3), 12 is the oil recovered from the hydraulic cylinder (3) Is an oil recovery pipe for reducing the pressure to the reserve tank 8, and 13 denotes a cable connecting plate provided at the tip of the cylinder 3, respectively.

이와같이 구성된 본 발명의 주차 브레이크 유격 조절장치의 동작에 대하여 설명하면, 본 발명은 차량을 운행시키거나 또는 주차 브레이크를 사용하지 않는 경우, 차량 내부에 설치된 유압센서(6)에서는 유압실린더(3)내의 일정유압을 감지한 후, 이를 이용하여 펌프(7)를 구동시키게 된다.Referring to the operation of the parking brake play control device of the present invention configured as described above, when the vehicle is driven or the parking brake is not used, the hydraulic sensor (6) installed inside the vehicle in the hydraulic cylinder (3) After detecting a constant hydraulic pressure, the pump 7 is driven using this.

즉, 상기 유압센서(6)에 의해 감지된 유압실린더(3)의 압력이 일정치 않아 주차 브레이크의 유격이 일정하게 유지되지 않을 경우, 상기 펌프(7)에서는 리저브 탱크(8)에서 공급되는 오일에 따라 펌프 동작하여 유압실린더(3)에 일정유압을 가하게 되는 것이다.That is, when the pressure of the hydraulic cylinder 3 sensed by the hydraulic sensor 6 is not constant and the clearance of the parking brake is not kept constant, the oil supplied from the reserve tank 8 is supplied from the pump 7. In accordance with the pump operation to apply a constant hydraulic pressure to the hydraulic cylinder (3).

다시말해, 펌프(7)의 펌핑동작을 통한 일정량의 오일이 오일공급관(11)을 거쳐 실린더(3) 내에 공급되면, 유압에 의해 피스톤(5)이 직선운동을 하게 되는데 이때 케이블(4)은 정지상태이므로 결국 실린더(3) 전체가 피스톤(5)와 상반된 방향으로 운동하게 되는 것이다. 따라서, 실린더(3) 선단에 설치되는 케이블 연결판(13)상의 구동케이블(10)이 실린더(3)가 이동한 거리만큼 간격을 조절하여 유격을 보상할 수 있게 되는 것이다.In other words, when a certain amount of oil through the pumping operation of the pump 7 is supplied into the cylinder 3 via the oil supply pipe 11, the piston 5 is linearly moved by hydraulic pressure, and the cable 4 is Since the stop state, the entire cylinder 3 eventually moves in a direction opposite to that of the piston 5. Therefore, the driving cable 10 on the cable connecting plate 13 installed at the front end of the cylinder 3 is able to compensate for the play by adjusting the interval by the distance the cylinder 3 is moved.

한편, 차량을 운행시키는 운전자가 주차브레이크 레버(1)를 작동시키는 경우, 상기 주차브레이크 레버(1)에 부착된 주차브레이크 스위칭부(2)에서는 온 스위칭 동작을 하여 차단밸브(9)를 동작시키게 된다.On the other hand, when the driver who drives the vehicle operates the parking brake lever 1, the parking brake switching unit 2 attached to the parking brake lever 1 performs an on switching operation to operate the shutoff valve 9. do.

상기 주차 레이크 스위칭부(2)의 온스위칭 동작에 따라 차단 밸브(9)에서는 펌프(7)의 펌프동작에 따라 유압실린더(3)내로 공급되는 유압을 차단시키기 위한 차단동작을 하여 유압실린더(3)로 공급되는 유압을 차단시키게 된다.According to the ounce switching operation of the parking rake switching unit 2, the shutoff valve 9 performs a shutoff operation to block the hydraulic pressure supplied into the hydraulic cylinder 3 according to the pump operation of the pump 7. ) Will cut off the hydraulic pressure.

이때, 케이블(4)에 의해 상기 주차브레이크 레버(1)와 연결된 피스톤(5)은 주차브레이크 레버(1)가 작동되더라도 유압실린더(3)내에서 항상 고정되어 있게 됨에 따라 주차브레이크의 작동에 의한 유압실린더(3)내의 유압변화를 방지하게 되는 것이다.At this time, the piston (5) connected to the parking brake lever (1) by the cable (4) is always fixed in the hydraulic cylinder (3) even if the parking brake lever (1) is operated by the operation of the parking brake It is to prevent the hydraulic change in the hydraulic cylinder (3).

이상에서 설명한 바와같이 본 발명은 주차 브레이크의 유격을 자동으로 항상 일정하게 조절시키는 시스템을 구성시키므로서, 주차 브레이크 사용시 유격조절을 간단하게 하여 차량 주차시에 발생되는 밀림현상을 방지하고, 이에따라 차량의 사용에 있어 안정성을 제공하는 효과가 있는 것이다.As described above, the present invention constitutes a system for automatically and constantly adjusting the play of the parking brake at all times, thereby simplifying the adjustment of the play when the parking brake is used, thereby preventing the phenomena occurring during parking of the vehicle, and thus It has the effect of providing stability in use.
