본 고안은 휠식 굴삭기등과 같이 바퀴를 부착한 중장비에서 주 브레이크 시스템의 이상 발생시, 비상제동용도로 사용하는 비상제동장치에 관한 것으로서, 상기한 중장비의 주행중 발생되는 비상제동상태를 후속 차량에 대해 충분한 경고를 시키므로서 추돌등의 사고를 미연에 예방하게 하는 비상제동장치에 관한 것이다.The present invention relates to an emergency braking device used for emergency braking in the event of a failure of the main brake system in a heavy equipment equipped with wheels such as a wheeled excavator, and the like. The present invention relates to an emergency braking device that provides a warning and prevents an accident such as a collision.
일반적으로 훨식 굴삭기등 바퀴에 의해 구동되는 중장비는 제1도에 도시된 바와같이, 액슬 휠을 제동하는 주 브레이크시스템(1)과 작업시 사용하는 주차브레이크시스템(2)으로 제동장치를 구성하고 있는데, 주 브레이크 시스템은 주행중인 차량을 감속시키거나 정지시키기 위한 것으로서, 페달(3) 조작에 의해 연동되는 브레이크 밸브(4)를 통해 유입된 압유가 휠 실린더의 피스톤을 양쪽으로 신장시킴에 의해 라이닝(6)이 확장되어 브레이크 드럼(5)내측면과 마찰력이 발생하므로 제동되도록 되어 있으며, 주차용 브레이크시스템(2)은 작업중 제동상태를 확고히 유지하기 위한 것으로서, 주차브레이크 스위치(9) 조작에 의해 콘트롤 밸브(11)를 통해 압유가 유입되고, 유입된 압유는 메인 샤프트(7)와 연결된 브레이크 드럼(8)의 외주면 및 내주면상에 위치하는 라이닝(13,14)을 차례로 연통하게 하여, 브레이크 드럼(8)에 대해 가압하게 되므로 확실한 제동상태를 유지하게 하는 것이다.In general, heavy equipment driven by wheels such as wheeled excavators consists of a main brake system (1) for braking the axle wheels and a parking brake system (2) for work, as shown in FIG. The main brake system is for decelerating or stopping a running vehicle. The hydraulic oil flowing through the brake valve 4 interlocked by the pedal 3 extends the piston of the wheel cylinder to both sides. 6) is extended so that the brake drum 5 and the inner surface of the brake is generated, so that the brake is applied, and the parking brake system 2 is to maintain the braking state during the operation, and is controlled by the parking brake switch 9 operation. The pressurized oil flows in through the valve 11, and the introduced pressurized oil is located on the outer circumferential surface and the inner circumferential surface of the brake drum 8 connected to the main shaft 7. To be communicated to the lining (13, 14) in turn, so that press against the brake drum 8 to maintain a certain braking conditions.
이상과 같이 구성된 제동장치가 구비된 차량이 주행중에 주 브레이크 시스템에 유압라인 파열등으로 인한 제반문제가 발생시 심각한 위험에 처하게 되는데, 종래의 경우 상기와 같은 상황에서 주차 브레이크시스템을 주행중에 그대로 사용하여 비상제동하였었다. 그런데, 비상제동시 주차등(10)은 점등되지만, 차량후미에 점등되는 브레이크등은 점등되지 않으므로 (주 브레이크 작동시에만 점등됨) 굴삭기등의 중장비가 도로상에서 주행도중에 비상제동할 경우에, 후미 차량에 대한 경고가 미흡하게 되어 추돌등에 의한 대형사고의 위험이 있었으며, 특히 차고가 낮은 차량이 후미에 있을시에는 시야가 방해받으므로, 그 문제가 더욱 심각했다.When the vehicle equipped with the braking device configured as described above is in serious danger when the main brake system breaks due to the hydraulic line rupture, etc., in the conventional case, the parking brake system is used as it is while driving. Emergency braking. However, the parking light 10 is turned on during the emergency braking, but the brake light that is turned on at the rear of the vehicle is not lit (it is lit only when the main brake is operated). The problem was more serious because of the lack of warnings and the risk of catastrophic accidents caused by collisions, especially when the vehicle with low garage was in the rear.
이에, 본 고안에서는 종래에 비상제동용으로 사용해온 주차 브레이크 시스템에 비상제동 스위치를 신설하여 주차 브레이크시스템 및 방향지시등 점멸시스템과 연계시킴으로서, 비상제동시에 비상제동스위치를 닫으면 주차 브레이크시스템이 작동되면서 동시에 양쪽 후미방향 지시등이 동시에 점멸되어 비상사태임을 후미차량에 충분히 경고토록 구성하였다.Therefore, in the present invention, by establishing an emergency braking switch in the parking brake system conventionally used for emergency braking and linking it with the parking brake system and the direction indicator flashing system, when the emergency braking switch is closed during emergency braking, the parking brake system is operated at the same time. Both rear turn indicators flashed at the same time, making sure that the tail car is fully alerted.
첨부도면에 의거하여 본 고안을 상세히 설명하면 다음과 같다.Referring to the present invention in detail based on the accompanying drawings as follows.
제2도는 본 고안인 제동장치의 회로도로서, 2개의 스위치(19,20)가 일체로 구성되어, 양쪽의 전류를 동시에 개폐제어하도록 이루어진 비상제동 스위치(18)에서, 각 스위치(19,20) 상호간의 개폐상태의 조합이 서로 엇갈리도록 구성되어 있고, 상기한 비상제동 스위치(18)를 구성하는 일개의 스위치(19)는 주차 브레이크시스템의 주차 브레이크스위치(9)와 전원과의 사이에 직렬로 연결되어 있으며, 나머지 일개의 스위치(20)는 방향지시등 점멸시스템의 양방향 점멸스위치(15)와 병렬로 연결되는 상태로 주차 브레이크시스템과 방향지시등 점멸시스템에 비상제동스위치(18)가 연계된 구조로 되어 있다.FIG. 2 is a circuit diagram of the braking device of the present invention, in which two switches 19 and 20 are integrally formed, and in the emergency braking switch 18 configured to simultaneously open and close both currents, each switch 19 and 20. One switch 19 constituting the emergency braking switch 18 is configured in such a manner that the combination of the opening and closing states of each other is mutually intersected in series between the parking brake switch 9 of the parking brake system and the power supply. The other switch 20 is connected to the bidirectional blinking switch 15 of the turn signal blinking system in parallel, so that the emergency brake switch 18 is connected to the parking brake system and the turn signal blinking system. It is.
이상과 같이 구성된 본 고안의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.
일상 주행상태에서는 비상제동스위치(18)의 주차시스템 제어용스위치(19)는 닫힌 상태이고, 이때 이에 직렬연결된 주차브레이크 스위치(9)는 상시 폐쇄스위치로서 계속 닫힌 상태이며, 역으로 제어되도록 구성된 콘트롤 밸브(11) 솔레노이드는 통전되지 않아서 압유의 유입이 이루어지지 않으며, 따라서 주차브레이크 시스템(2)은 작동하지 않는다. 또한, 비상제동 스위치(18)에서의 방향지시등 점멸시스템 제어용 스위치(20)는 개방상태이므로 방향지시등(17)은 점멸하지 않는다.In the daily driving state, the parking system control switch 19 of the emergency braking switch 18 is in a closed state. At this time, the parking brake switch 9 connected in series is kept closed as an normally closed switch and is controlled to be reversely controlled. (11) The solenoid is not energized so that the inflow of the pressurized oil does not occur, and therefore the parking brake system 2 does not operate. In addition, since the turn indicator flashing system control switch 20 in the emergency braking switch 18 is in an open state, the turn indicator 17 does not blink.
그러나, 주행중 비상제동스위치(18)를 누르면 제3도에 도시된 바와 같이 주차시스템 제어용스위치(19)는 개방되므로, 역으로 제어되도록 구성된 콘트롤 밸브(11) 솔레노이드는 통전되어 압유가 주차브레이크 드럼(8) 외주상에 위치한 외측 라이닝(13)작동부와, 드럼 내주상에 위치한 내측 라이닝(14)작동부에 순차적으로 유입되어 메인샤프트(7)와 함께 회전하는 브레이크 드럼(8)을 양측 라이닝(13,14)이 압압하여 제동하게 되므로 비상제동된다. 또한, 상기 동작과 동시에 비상제동 스위치(18)의 방향지시등 점멸시스템 제어용스위치(20)는 닫히게 되므로 양쪽의 방향지시등(17a,17b)이 동시에 점멸하여 비상제동상태임을 표시하게 된다.However, when the emergency braking switch 18 is pressed while driving, the parking system control switch 19 is opened as shown in FIG. 3, so that the control valve 11 solenoid configured to be reversely controlled is energized so that the hydraulic oil is applied to the parking brake drum ( 8) Both side linings of the brake drum 8, which is sequentially introduced into the outer lining 13 operating part located on the outer circumference and the inner lining 14 operating part located on the drum inner circumference, rotate together with the main shaft 7; 13, 14) is pressed and braked, so emergency braking. In addition, the direction indicator flashing system control switch 20 of the emergency braking switch 18 is closed at the same time as the above operation, so that both the direction indicators 17a and 17b flash at the same time to indicate that the emergency braking state.
정차중의 주차브레이크 조작의 경우는 비상제동 스위치(18)가 동작하지 않으므로 종래의 경우와 같다.In the case of parking brake operation while stopped, the emergency braking switch 18 is not operated, which is the same as the conventional case.
이상에서 기술한 비상제동장치는 휠식 굴삭기등과 같이 바퀴에 의해 구동되는 중장비에 사용할 경우, 상기 차량에 의해 전방시야를 방해받은 상태로 중장비에 사용할 경우 상기 차량에 의해 전방시야를 방해받은 상태로 추종하던 후방차량의 추돌사고를 예방하기 위한 경고효과를 발휘할 수 있을 뿐만아니라 구조가 복잡하지 않으므로 제조 단가가 저렴하며, 기존의 모든 바퀴구동식 중장비에도 용이하게 설치 가능하다.The emergency braking device described above is used in heavy equipment driven by wheels, such as a wheeled excavator, and is obstructed by the vehicle when the front view is obstructed when used in heavy equipment. It can not only exert warning effect to prevent crash of the rear vehicle, but also the structure is not complicated, so the manufacturing cost is low, and it can be easily installed in all existing wheel-driven heavy equipment.
