4륜구동 차량의 일반적인 견인을 가능하게 하는 장치{a device for making general traction of a 4WD car available}A device for making general traction of a 4WD car available}

본 발명은 4륜구동 차량의 견인에 관한 것으로서, 보다 상세하게는 일반적으로 차량의 전륜만을 들어올려 차량을 견인하는 일반적인 견인방법으로도 견인이 가능하도록 하기 위해 상시 4륜구동(full time 4 wheel drive) 차량에 적용될 수 있는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to towing of a four wheel drive vehicle. More particularly, the present invention relates to a full time four wheel drive vehicle in order to be able to be towed by a general towing method in which only the front wheels of the vehicle are lifted. It relates to a device that can be applied to.

도 1과 도 2에는 4륜구동 차량에 적합한 견인 방법이 도시되어 있는바, 그 핵심은 차량의 전륜과 후륜을 모두 노면으로부터 이탈시킨 상태에서 피견인차량을 이동시켜야 한다는 것이다.1 and 2 show a towing method suitable for a four-wheel drive vehicle, the core of which is to move the towed vehicle with both the front and rear wheels of the vehicle removed from the road surface.

그런데, 4륜구동 차량을 도 3에 도시된 바와 같이 일반적인 견인 방법으로 견인하면, 즉 전륜과 후륜을 모두 들어올리지 않고 한쪽의 차륜만을 들어올린 상태에서 견인을 하게 되면, 노면에 접촉되어 있는 차륜으로부터 피견인차량의 내부로 구동력이 역으로 전달되어 전후륜간 비정상적인 회전차 발생 및 상시 4륜시스템의 핵심부품인 동력배분 및 차동제한장치의 파손이 발생하는 문제점이 있다.However, if the tow vehicle is towed by a general towing method as shown in Fig. 3, that is, towing in a state in which only one wheel is lifted without lifting both the front wheel and the rear wheel, the towing vehicle is pulled from the wheel in contact with the road surface. As the driving force is transmitted to the inside of the vehicle inversely, there is a problem that an abnormal rotation difference is generated between the front and rear wheels and the power distribution and the differential limiting device, which are the core components of the all four wheel system, occur.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 일반적인 견인 방법으로도 4륜구동 차량의 견인이 가능하도록 하여 편리한 견인이 이루어질 수 있도록 하는 4륜구동 차량의 일반적인 견인을 가능하게 하는 장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems as described above, the device to enable the general traction of the four-wheel drive vehicle to enable the towing of the four-wheel drive vehicle in a general traction method to enable convenient traction. The purpose is to provide.

상기한 바와 같은 목적을 달성하기 위한 본 발명 4륜구동 차량의 일반적인 견인을 가능하게 하는 장치는 변속기와 리어액슬의 사이를 연결하는 추진축을 양분하고 그 사이에 설치된 클러치수단과;A device for enabling general traction of a four-wheel drive vehicle of the present invention for achieving the above object comprises: a clutch means bisecting a propulsion shaft connecting between a transmission and a rear axle;

운전자의 탑승 상태에 따라 상기 클러치수단을 선택적으로 작동시키는 클러치 작동수단으로 구성된 것을 특징으로 한다.Characterized in that the clutch operating means for selectively operating the clutch means according to the driver's riding state.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 4는 본 발명에 따른 4륜구동 차량의 일반적인 견인을 가능하게 하는 장치의 바람직한 실시예를 도시한 것으로서, 변속기(1)와 리어액슬(2)의 사이를 연결하는 추진축(3)을 양분하고 그 사이에 설치된 클러치수단과, 운전자의 탑승 상태에 따라 상기 클러치수단을 선택적으로 작동시키는 클러치 작동수단으로 구성되어 있다.FIG. 4 shows a preferred embodiment of a device which enables a general traction of a four-wheel drive vehicle according to the invention, which bisects the propulsion shaft 3 which connects between the transmission 1 and the rear axle 2. Clutch means provided between and the clutch operating means for selectively operating the clutch means in accordance with the driver's riding state.

상기 클러치수단은 상기 양분된 추진축(3)의 사이에 설치된 유체박스(5)와 상기 유체박스(5)의 내부에서 상기 양분된 추진축(3)을 상호 연결하도록 설치된 습식다판클러치(7)로 구성되며, 상기 클러치작동수단은 운전자의 체중에 의해 하향 작동하는 피스톤(9)과, 상기 피스톤(9)의 상하운동을 가이드함과 아울러 압유가 충전되어 있고 상기 유체박스(5)에 압유를 전달할 수 있도록 연결된 실린더(11)와, 상기 피스톤(9)을 상측으로 탄지하는 스프링(13)으로 구성되어 있다.The clutch means is composed of a wet multi-plate clutch 7 installed to interconnect the bisected propulsion shaft 3 inside the fluid box 5 and the bisected propulsion shaft 3. The clutch actuating means guides the piston 9 which is operated downward by the weight of the driver, the vertical movement of the piston 9, and is filled with pressure oil, and may transmit the pressure oil to the fluid box 5. It consists of a cylinder 11 connected so that it may be connected, and a spring 13 for holding the piston 9 upwards.

여기서, 상기 유체박스(5)와 추진축(3)의 사이에는 베어링(15)으로 지지되어 있어서, 추진축(3)의 회전이 원활한 상태로 확보될 수 있도록 하며, 상기 유체박스(5)는 차체에 고정되게 된다.Here, the bearing 15 is supported between the fluid box 5 and the propulsion shaft 3 so that the rotation of the propulsion shaft 3 can be secured in a smooth state, and the fluid box 5 is attached to the vehicle body. It will be fixed.

한편, 상기 양분된 두 추진축(3)을 연결하는 습식다판클러치(7)는 유압이 제공되면 두 추진축(3)을 연결하고, 유압이 해제되면 두 추진축(3)을 서로 분리시키는 일반적인 공지의 습식다판클러치가 사용된다.Meanwhile, the wet multi-plate clutch 7 connecting the two divided propulsion shafts 3 connects the two propulsion shafts 3 when the hydraulic pressure is provided, and separates the two propulsion shafts 3 from each other when the hydraulic pressure is released. Multi-plate clutches are used.

또한, 상기 운전석에 설치되는 피스톤(9)은 운전자의 승차감을 저해하지 않은 상태에서 단지 운전자의 체중만을 전달받을 수 있는 상태로 적절히 설치하도록 한다.In addition, the piston (9) installed in the driver's seat is to be properly installed in a state that can receive only the driver's weight in a state that does not impair the driver's comfort.

상기한 바와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

운전자가 운전석에 앉아 있는 상태는 견인을 요구하는 상태가 아니고, 운전자에 의해 정상적으로 차량이 작동하여야 하는 상태로서, 이때에는 운전자가 운전석에 앉음으로써 피스톤(9)에 전해지는 운전자의 체중에 의해 상기 실린더(11)내의 압유가 유압을 발생시켜 상기 유체박스(5)에 공급된다.The driver sitting in the driver's seat is not a state requiring towing, but a state in which the vehicle should be normally operated by the driver. In this case, the cylinder is caused by the weight of the driver transmitted to the piston 9 by sitting in the driver's seat. The pressurized oil in 11 generates hydraulic pressure and is supplied to the fluid box 5.

따라서, 상기 유체박스(5)내에 설치된 상기 습식다판클러치(7)가 작동되어 양분되었던 추진축(3)을 하나로 연결하게 되어 변속기로부터의 동력은 리어액슬(2)로 적절히 공급되는 상태가 되어 정상적인 4륜구동의 상태가 확보된다.Accordingly, the wet multi-plate clutch 7 installed in the fluid box 5 is operated to connect the divided propulsion shafts 3 into one, so that the power from the transmission is properly supplied to the rear axle 2 so that the normal 4 The state of the wheel drive is secured.

한편, 차량을 견인해야 할 경우에는 운전자가 탑승하지 않으므로 상기 피스톤(9)은 상기 스프링(13)에 의해 상승하여 상기 실린더(11) 내에는 유압이 발생하지 않으므로 상기 유체박스(5) 내의 습식다판클러치(7)에도 유압이 공급되지 않게 된다.On the other hand, when the vehicle is towed, the driver does not board, so the piston 9 is lifted by the spring 13 so that no hydraulic pressure is generated in the cylinder 11, so that the wet multi-plate in the fluid box 5 Hydraulic pressure is also not supplied to the clutch 7.

따라서, 상기와 같은 상태에서는 후륜이 상기 습식다판클러치(7)에 의해 변속기(1)로부터 절연되는 상태가 되어, 일반적인 견인 방법을 적용하여 전륜만을 들고 후륜이 노면에 닿는 상태가 되어도, 상기 후륜으로부터의 회전력은 상기 습식다판클러치(7)에 의해 차단되어 동력배분 및 차동제한장치의 파손을 방지할 수 있게 된다.Therefore, in the above state, even if the rear wheel is insulated from the transmission 1 by the wet multi-plate clutch 7, even if the rear wheel is brought into contact with the road surface by applying a general traction method, The rotational force of is blocked by the wet multi-plate clutch (7) to prevent breakage of the power distribution and the differential limiting device.

이상과 같이 본 발명에 의하면, 운전자의 탑승여부에 따라 양분된 추진축이 서로 연결되는 상태와 단절되는 상태가 절환되도록 함으로써, 일반적인 견인 방법으로도 4륜구동 차량의 견인이 가능하도록 하여 편리한 견인이 이루어질 수 있도록 한다.As described above, according to the present invention, the state in which the divided propulsion shafts are connected to each other and disconnected from each other according to the driver's boarding state is switched, so that the towing of the four-wheel drive vehicle can be performed by a general towing method, thereby allowing convenient towing. Make sure
