Description

보조제동장치Auxiliary Braking System
본 발명은 자동차의 보조 제동장치에 관한 것으로, 보다 상세하게는 자동차의 제동시 자동차의 구동력이 전달되는 바퀴면과 노면 사이에 제동패널을 삽입하여 바퀴의 구동력을 상실하게 하는 보조제동장치에 관한 것이다.The present invention relates to an auxiliary braking device for a vehicle, and more particularly, to an auxiliary braking device for inserting a braking panel between a wheel surface and a road surface to which the driving force of the vehicle is transmitted when the vehicle is braked to lose the driving force of the wheel. .
일반적으로 자동차에는 두 가지의 제동장치가 있다. 주행중에 바퀴에 직접 제동작용을 하는 풋브레이크와, 주차시킬 때에 사용되는 핸드브레이크가 있다.In general, there are two types of brakes in automobiles. There are a foot brake that directly brakes the wheel while driving and a hand brake which is used for parking.
이러한 제동장치들은 기계적으로 바퀴를 구동시키는 실린더와 구동축에 마찰을 가하여 멈추는 방식으로 엔진의 구동력과 차체의 속력에 따라서 자동차의 제동거리가 변화한다.These braking devices mechanically drive the wheels by applying friction to the cylinder and the driving shaft to stop the braking distance of the vehicle according to the driving force of the engine and the speed of the vehicle body.
이러한 구동축에 직접적으로 마찰을 가하는 제동방법은 자동차가 높은 속도로 운행될 때에 제동할 경우, 구동축이 가지고 있는 강한 구동력과 회전력이 의해 제동거리가 길어지게 되어 위험한 사고를 일으킬 수 있다. 또한, 타이어가 손상된 채 휠이 도로상에 마찰이 될 경우에는 제동력을 잃게 되며 기존의 제동장치로 제어를 할 수 없게 된다.In the braking method of directly applying a friction to the driving shaft, when the vehicle is braked at a high speed, the braking distance is increased by the strong driving force and the turning force of the driving shaft, which may cause a dangerous accident. In addition, when the tire is damaged and the wheel is rubbed on the road, the braking force is lost, and the conventional braking device cannot control it.
주 제동장치가 고장이 나거나 현재, 규명되지 않았지만 계속 발생되는 엔진 급발진의 사고의 경우, 바퀴는 끊임없이 강한 구동력을 가지게 되므로 기존의 제동장치로 제어를 할 수 없어 사고를 막을 수 없는 문제점이 있었다.In the case of the main braking device failure or present, but not yet identified, but the engine suddenly occurring accident, the wheel has a constantly strong driving force, there is a problem that can not control the conventional braking device to prevent the accident.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창출된 것으로, 그 목적은 자동차의 기존의 제동장치로 제동제어를 할 수 없을 때 작동하는 보조제동장치로서, 구동되는 바퀴의 전면차측에 구비된 제동패널이 사용시 배출되어, 구동되는 바퀴의 바닥면을 감싸 노면과 바퀴와의 마찰을 분리시키는 보조제동장치를 제공함에 있다.The present invention was created in order to solve the above-mentioned conventional problems, and an object thereof is an auxiliary braking device that operates when a braking control cannot be performed with a conventional braking device of a vehicle, and is provided on the front side of a wheel to be driven. The braking panel is discharged during use to provide an auxiliary braking device that surrounds the bottom surface of the driven wheel to separate the friction between the road surface and the wheel.

Furthermore, the auxiliary braking apparatus according to an embodiment of the present invention may further include a control unit for monitoring driving status information of the vehicle and transmitting an operation signal to the braking panel operation unit based on the monitored driving status information. .

Specifically, the upper surface may be formed of a metal material, and the lower surface may be formed of a rubber material.

이때, 바퀴(2)의 구동력은 노면으로 전달되지 않고, 제동패널(31)과 노면 사이에 마찰력을 기초로 차량의 제동이 가능하게 된다. 이것은 운전자가 바퀴의 구동력을 제어하지 못하는 비상상황에서 매우 유용하다. 제동패널(31)은 제동패널작동부(32)에 의해 설정해 놓은 일정시간마다 조금씩 설정된 일정간격으로 순차적으로 배출될 수 있다. 이에 따라, 바퀴(2)와 노면사이에 개재된 제동패널의 마찰면이 순차적으로 이동하게 되므로 마찰면이 닳아버린다 해도 조금씩 이동함에 따라 새로운 마찰면이 유지된다.At this time, the driving force of the wheel 2 is not transmitted to the road surface, and the braking of the vehicle is possible based on the friction force between the braking panel 31 and the road surface. This is very useful in emergencies where the driver cannot control the driving force of the wheels. The braking panel 31 may be sequentially discharged at predetermined intervals set little by little at a predetermined time set by the braking panel operation unit 32. Accordingly, since the friction surface of the braking panel interposed between the wheels 2 and the road surface is sequentially moved, even if the friction surface is worn out, the new friction surface is maintained as it moves little by little.
상기 제동패널작동부(32)는 차량 제동이 가능하도록 자동차(1)의 차량 골조가 되는 차체 프레임에 연결된다.The braking panel operation part 32 is connected to a vehicle body frame that becomes a vehicle frame of the vehicle 1 to enable vehicle braking.
또한, 도 3에 도시된 바와 같이, 상기 제동패널작동부(32)는 차량에 구비된 조작 스위치(35)에 의해 작동될 수 있다. 상기 조작 스위치(35)는 운전석, 보조석 및 각 승용석 중 어느 하나 이상에 구비되어 위급시 쉽게 사용가능하도록 할 수 있다.In addition, as illustrated in FIG. 3, the brake panel operation unit 32 may be operated by an operation switch 35 provided in the vehicle. The operation switch 35 may be provided in any one or more of the driver's seat, the auxiliary seat, and each passenger seat so that it can be easily used in an emergency.
나아가, 차량 내에 구비된 제어부(34)는 차량의 운행 상황을 모니터링하여, 모니터링된 운행 상황의 정보를 기초로 생성되는 작동신호를 제동패널작동부(32)로 전송하거나, 또는 상기 조작 스위치(35)를 자동으로 작동하도록 함으로써 작동신호를 제동패널작동부(32)로 전송할 수 있다. Furthermore, the control unit 34 provided in the vehicle monitors the driving state of the vehicle, and transmits an operation signal generated based on the monitored driving state information to the braking panel operation unit 32, or the operation switch 35. ) Can be automatically transmitted to the braking panel operation unit 32.
이때, 제어부(34)는 차량에 구비된 주 제동장치(풋브레이크, 핸드브레이크)에 작용하는 하중이 설정된 하중범위를 벗어날 경우 작동신호를 생성하여, 제동패널작동부(32)로 전송할 수 있다. At this time, the control unit 34 may generate an operation signal when the load acting on the main braking device (foot brake, hand brake) provided in the vehicle is out of the set load range, it may be transmitted to the braking panel operation unit 32.
나아가, 제어부(34)는 차량 차체에 구비된 가속도센서에 의해 검출된 값이 설정된 수치범위에 해당될 경우 작동신호를 생성하여, 제동패널작동부(32)로 전송할 수 있다. 예를 들면, 급정거 시 쏠림 현상이 지속될 경우 제어부(34)는 주 제동장치에 과부하가 걸린 것으로 판단하고 자동으로 작동신호를 생성하여 제동패널작동부(32)로 전송할 수 있다.In addition, the controller 34 may generate an operation signal when the value detected by the acceleration sensor included in the vehicle body corresponds to the set numerical range, and transmit the operation signal to the braking panel operation unit 32. For example, if the tilting phenomenon continues during sudden stop, the controller 34 determines that the main braking device is overloaded, and automatically generates an operation signal and transmits it to the braking panel operation unit 32.
또한, 제어부(34)는 주 제동장치(풋브레이크, 핸드브레이크)가 작동되었음에도 불구하고 설정된 시간 이상 차량이 정지하지 않아 제동 불량으로 감지된 경우, 작동신호를 생성하고 이를 상기 제동패널작동부(32)로 전송하여, 제동패널(31)이 작동되도록 하는 것도 가능하다. In addition, when the main braking device (foot brake, hand brake) is activated even if the vehicle does not stop for a predetermined time or more, but the braking failure is detected, the control unit 34 generates an operation signal and the braking panel operation unit 32 ), It is also possible to operate the braking panel 31.
여기서, 제동패널(31)의 상부면은 바퀴(2)와의 마찰을 최소화하여 바퀴(2)가 제동패널(31)의 상부면 위에서 미끄러질 수 있도록 하는 것이 바람직하다. 한편, 제동패널(31)의 하부면은 노면과 맞닿아 차량을 제동해야 하므로 상부면 보다 마찰계수가 큰 재질 또는 형상으로 형성한다. 나아가, 차량의 제동력을 향상시키기 위해 제동패널(31)의 하부면은 바퀴(2)의 타이어보다 노면에 닿는 면적이 더 넓은 면적을 구비하도록 형성될 수도 있다. Here, it is preferable that the upper surface of the braking panel 31 minimizes friction with the wheel 2 so that the wheel 2 can slide on the upper surface of the braking panel 31. On the other hand, since the lower surface of the braking panel 31 must be in contact with the road surface to brake the vehicle, the lower surface of the braking panel 31 is formed of a material or shape having a larger friction coefficient than the upper surface. Furthermore, in order to improve the braking force of the vehicle, the lower surface of the braking panel 31 may be formed to have a larger area of contact with the road surface than the tire of the wheel 2.

제동패널작동부(32)가 작동하면 상기 접점마찰부(315)는 차량의 바퀴(2)와 노면사이에 끼어들어간다. 여기서 제동패널(31)의 종단은 노면과 바퀴(2) 사이로 삽입이 용이하도록 경사지게 형성된 경사부(312)가 구비될 수 있다.When the brake panel operating part 32 operates, the contact friction part 315 is interposed between the wheel 2 and the road surface of the vehicle.

The contact friction part 315 includes a tire friction part 331 forming an upper surface and a ground friction part 332 forming a lower surface. The tire friction portion 331 is preferably formed to be smooth so that the driving force of the tire is not transmitted, the ground friction portion 332 is preferably formed of a material or shape having a friction force capable of braking the vehicle body. The tire friction portion 331 and the ground friction portion 332 may be integrally formed or formed of different materials. In one embodiment, the tire friction portion 331 is formed of a metal material, the ground friction portion 332 may be formed of the same rubber material as the tire, but is not limited thereto. In addition, the ground friction unit 332 may include a tire pattern formed on the tire to improve the braking force.
일 실시예에서, 제동패널(31)은 넓고 기다란 판형으로 이루어질 수 있으나, 그 형상은 이에 한정하지 않는다. 제동패널(31)은 체인형태로 이루어지거나 접철식으로 접혀 구비될 수 있다.In one embodiment, the braking panel 31 may be made of a wide and elongated plate, but the shape thereof is not limited thereto. The braking panel 31 may be provided in a chain form or folded in a folding manner.
도 5 는 본 발명의 일 실시예에 따른 제동패널의 구조 예시도이고, 도 6 은 본 발명의 일 실시예에 따른 제동패널의 롤러 구비 상태를 설명하기 위한 측면 예시도이다.5 is a diagram illustrating a structure of a braking panel according to an embodiment of the present invention, Figure 6 is a side view illustrating a roller equipped state of the braking panel according to an embodiment of the present invention.
도 5 및 도 6의(a)에 도시된 실시예에서, 제동패널(31)의 상부면에 구비된 타이어마찰부(331)는 제동패널(31)의 길이 방향으로 배열된 다수의 롤러(311)를 포함할 수 있다. 이때, 구동되는 바퀴(2)는 상기 다수의 롤러(311)에 올라가 회전하고, 바퀴(2)의 구동과 상관없이 제동패널(31)의 하부면이 노면과 맞닿아 보다 효율적으로 차량을 제동시킬 수 있다. 5 and 6 (a), the tire friction portion 331 provided on the upper surface of the braking panel 31 has a plurality of rollers 311 arranged in the longitudinal direction of the braking panel 31. ) May be included.
