It is connected in series from the brake switch and the power supply, and the forward and backward control valves are connected in parallel with the parking brake solenoid valve with respect to the parking brake switch, while the selection valves for the first and second stages are transmission control switches. It is configured to be grounded immediately from.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 차량의 운전석에 설치된 변속기제어스위치판넬(1)에 유압펌프(2)에서 가압·공급되는 압유의 흐름을 제어절환시켜 주는 2개의 솔레노이드밸브(3, 4)가 전기적으로 연결되어 있는데, 이중1, 2단 변속용 솔레노이드밸브(3)는 양쪽의 솔레노이드(3a, 3b)를 매개하여 상기 제어스위치판넬(1)의 Lo단 및 Hi단의 단자와 각각 연결되어 상기 솔레노이드(3a, 3b)쪽에서 곧바로 접지되도록 되어 있고, 상기 전, 후진용 솔레노이드밸브(4)는 양쪽의 솔레노이드(4a, 4b)를 매개하여 상기 제어스위치판넬(1)의 F단 및 R단의 단자와 각각 연결되어 있다.According to the present invention, two solenoid valves 3 and 4 are electrically connected to a transmission control switch panel 1 installed in a driver's seat of a vehicle to control and switch the flow of pressurized oil supplied from the hydraulic pump 2. The solenoid valve 3 for double and double shifting solenoids 3 is connected to the terminals of the Lo and Hi terminals of the control switch panel 1 via the solenoids 3a and 3b on both sides of the solenoid 3a and 3b, respectively. It is to be immediately grounded at the side, and the front, reverse solenoid valve (4) is connected to the terminals of the F terminal and the R terminal of the control switch panel (1) via the solenoid (4a, 4b) of both sides, respectively.
그리고 상기 각 솔레노이드밸브(3, 4)는 이들 밸브를 거쳐나온 압유가 변속기의 1, 2단 변속실린더 및 전. 후진 선택실린더(도시안됨)와 공급되도록 연결되어 있고, 상기 유압펌프(2)에서 주차브레이크(8)로 공급되는 압유의 흐름을 제어·절환해주는 주차브레이크용 솔레노이드밸브(7)는 해당 솔레노이드(7a)를 매개하여 밧데리의 ＋단자 및 주차브레이크스위치(6)와 각각 전기적으로 연결되어 있으며, 상기 주차브레이크스위치(6)의 C단자에 연결된 접지부(9)를 통해 접지되어 있다.Each of the solenoid valves (3, 4) is the first and second gear shift cylinder and the front. Parking brake solenoid valve (7) connected to the reverse selection cylinder (not shown) and controlling and switching the flow of hydraulic oil supplied from the hydraulic pump (2) to the parking brake (8) is the solenoid (7a). It is electrically connected to the + terminal of the battery and the parking brake switch 6, respectively, and is grounded through the grounding part 9 connected to the C terminal of the parking brake switch 6 through).
따라서 상기 주차브레이크용 솔레노이드밸브(7)는 주차브레이크스위치(6)의 온·오프(ON, OFF)에 따라 상기 주차브레이크용 솔레노이드밸브(7)가 절환작동되면서 유압펌프(2)에서 공급되는 압유를 주차브레이크(8)에 공급 또는 주차브레이크(8)의 압유를 탱크로 드레인시킴으로써 브레이크가작동 또는 브레이크작동을 해제시키도록 되어 있다.Therefore, the parking brake solenoid valve 7 is pressurized oil supplied from the hydraulic pump 2 while the parking brake solenoid valve 7 is switched according to the on / off of the parking brake switch 6. Is supplied to the parking brake 8 or the pressure oil of the parking brake 8 is drained to the tank so as to release the brake operation or brake operation.
그리고 전. 후진용 솔레노이드밸브(4)의 양쪽 솔레노이드(4a, 4b)는 상기 솔레노이드밸브(7)와 주차브레이크스위치(6)를 연결시키는 도선의 중간지점에서 병열로 연결되어 상기 전. 후진 솔레노이드밸브(4) 역시 주차브레이크스위치(6)의 ON/OFF작동에 따라 상기 제어스위치판넬(1)의 각 선택단자에서 인가된 전류가 통전됨으로써 절환작동하면서 변속기(5)를 전. 후진단으로 선택해 줄수 있게 되어 있다.And ex. Both solenoids (4a, 4b) of the reverse solenoid valve (4) are connected in parallel at the intermediate point of the conductor connecting the solenoid valve (7) and the parking brake switch (6). The reverse solenoid valve (4) also transfers the transmission (5) while switching by operating the current applied from each selection terminal of the control switch panel (1) according to the ON / OFF operation of the parking brake switch (6). It is possible to choose for backward diagnosis.
상기한 바와같은 구조로된 본 고안의 작동과정을 전진 1단으로 주행하고자 하는경우를 설명한다.It will be described a case in which the operation process of the present invention having the structure as described above to drive in the first step forward.
먼저 변속기제어스위치판넬(1)의 B+단자에는 밧데리 ＋단자가 연결되어 있고, 이 B+단자와 F, N, R, Lo, 및 Hi의 각 단자는 스위치의 접촉편으로 직접연결되어 있으므로, 상기 변속기제어스위치판넬(1)을 통해 전류를 공급받는 1, 2단 변속용 솔레노이드밸브(3)와, 전. 후진용 솔레노이드밸브(4) 및, 휴우즈(10)를 거쳐 밧데리로부터 직접전류를 공급받는 주차브레이크용 솔레노이드밸브(7)에는 모두 ＋극의 전류가 흐르게 된다.First, the battery + terminal is connected to the B + terminal of the transmission control switch panel 1, and the B + terminal and each terminal of F, N, R, Lo, and Hi are directly connected to the contacting part of the switch. 1 and 2 speed solenoid valves (3) for receiving current through the transmission control switch panel (1), and A positive pole current flows to both the reverse solenoid valve 4 and the solenoid valve 7 for parking brake, which is directly supplied from the battery via the fuse 10.
그런데 상기 1, 2단 변속용 솔레노이드밸브(3)는 각 솔레노이드(3a, 3b)가 직접 바로 접지되어 있으므로 상기 스위치판넬(1)에서 1단 또는 2단을 선택하기만 하면 곧바로 1, 2단 변속용 밸브(3)가 절환작동되면서 변속기(5)를 1단 또는 2단으로 선택해 주게 되나, 상기 전. 후진용 솔레노이드밸브(4)와 주차브레이크용 밸브(7)의 각 해당 솔레노이드(4a, 4b, 7a)는 모두 주차브레이크스위치(6)를 매개하여 접지부(9)와 연결되어 있으므로, 이 주차브레이크스위치(6)가 접지상태로 절환되어야만 통전되어 상기 전. 후진용 밸브(4)와 주차브레이크용밸브(7)가 작동되게 된다.However, since the solenoids 3a and 3b of the 1 and 2 gearing solenoid valve 3 are directly grounded, the 1 and 2 gearings can be made by simply selecting 1 or 2 gears in the switch panel 1. When the valve 3 is switched, the transmission 5 is selected in one or two stages. Each of the respective solenoids 4a, 4b, and 7a of the reversing solenoid valve 4 and the parking brake valve 7 is connected to the ground portion 9 via the parking brake switch 6, so that the parking brake The switch (6) must be switched to the ground state to energize the power. The reverse valve 4 and the parking brake valve 7 are operated.
따라서 먼저 브레이킹 되어 있는 차량을 브레이킹 OFF시키기 위해 주차브레이크스위치(6)를 OFF시키면, 이 스위치(6)의 압력단자인 A단자와 출력단자이면서 접지부(9)와 연결되어 있는 C단자가 연결되면서 ＋극의 전류가 접지되게 되므로 통전되어 상기 주차브레이크용 밸브(7)가 솔레노이드(7a)에 의해 절환작동되면서 브레이크(8)에 충전되어 있던 압유가 탱크로 귀환되어 브레이크해제 되게 된다.Therefore, when the parking brake switch 6 is turned off in order to brake the vehicle that has been braked first, the terminal A, which is the pressure terminal of the switch 6, and the terminal C, which is connected to the ground part 9 and the output terminal, are connected. Since the + pole current is grounded, it is energized so that the parking brake valve 7 is switched by the solenoid 7a and the pressurized oil charged in the brake 8 is returned to the tank to release the brake.
이러한 상태에서 전진 또는 후진 스위치를 선택하면 스위치판넬(1)의 해당 출력단자에서 출력된 전류가 전. 후진용 밸브(4)의 솔레노이드(4a, 4b)를 거쳐 상기 주차브레이크스위치(6)의 접지부(9)를 통해 접지되므로, 상기 전. 후진용 밸브(4)가 선택된 방향으로 절환되면서 압유가 변속기(5)의 전. 후진실린더로 주입작동되게 된다. 그다음 스위치판넬(1)에서 1단을 선택하면 곧바로 접지통전되므로 압유가 변속기(5)의 1단실린더로 주입되어 변속됨으로써 차량이 전진1단으로주행하게 된다.In this state, if forward or reverse switch is selected, current output from corresponding output terminal of switch panel (1) is forwarded. Through the solenoid (4a, 4b) of the reverse valve (4) through the ground (9) of the parking brake switch (6), the front. As the reverse valve (4) is switched in the selected direction, the hydraulic oil is transferred to the transmission (5). Injection into the reversing cylinder is performed. Then, when the first stage is selected in the switch panel 1, the ground is energized immediately, so that the hydraulic oil is injected into the first stage cylinder of the transmission 5 and shifted so that the vehicle travels to the first forward stage.
물론 경우에 따라서는 변속단을 1단으로 먼저 선택해 두고 브레이크를 해제함과 더불어 차량을 전. 후진 시키게 할 수도 있다.In some cases, of course, the gearbox is selected as the first gear, the brake is released, and the vehicle is moved. It can also be reversed.
기타 나머지 다른 변속단과 후진주행은 스위치판넬(1)에서의 스위치선택과정만 상이하고 기타 다른 부품들의 작동과정은 동일하므로 개개의 경우에 대해서는 설명을 생략한다.The rest of the shift stage and the reverse driving differ only in the switch selection process in the switch panel 1, and the operation process of the other parts is the same, and thus descriptions of individual cases are omitted.
이상에서 설명한 바와같이 본 고안의 장치는 차량의 브레이킹 상태를 해제시키지 않으면 전기적으로 전. 후진 선택밸브가 작동되지 않으므로 차량을 이동시킬 수가 없게 되어, 종래의 주차브레이크를 해제시키지 않고 차량을 길게 주행시킴으로써 발생되는 브레이크파열 등과 같은 문제를 완전히 해소시켜 줄 수가 있다.As described above, the device of the present invention is electrically powered unless the vehicle is braked. Since the reverse selection valve is not operated, the vehicle cannot be moved, thereby completely eliminating problems such as a brake rupture caused by driving the vehicle for a long time without releasing the conventional parking brake.
