Description
본 발명은 자동차의 4륜구동 절환장치에 관한 것으로서, 특히 유압에 의하여 구동축을 필요에 따라 일체화하게 됨으로써 기계적으로 용이하게 작동되도록 한 자동차의 4륜구동 절환장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a four-wheel drive switching device for an automobile, and more particularly, to a four-wheel drive switching device for an automobile that is easily mechanically operated by integrating a drive shaft as necessary by hydraulic pressure.
일반적으로 4륜 구동방식에는 항시 4륜 구동하는 풀 타입과, 주행 조건에 따라서 2륜구동과 4륜구동을 선택할 수 있는 파트 타입이 있다.In general, the four-wheel drive system includes a full type that always drives four wheels, and a part type that can select two-wheel drive and four-wheel drive according to the driving conditions.
상기 풀 타입은 구동력을 앞바퀴 구동축과 뒷바퀴 구동축으로 균등하게 분배하며 선회시 앞/뒷바퀴의 회전차를 흡수하며, 그 방식에 따라 비스커스 커플링 방식과, 센터디프렌셜 방식 등으로 분류된다.The pull type distributes the driving force equally to the front wheel drive shaft and the rear wheel drive shaft and absorbs the rotation difference of the front / rear wheels during turning, and is classified into a biscus coupling method and a center differential method according to the method.
상기 비스커스 커플링 방식은 앞바퀴의 좌우측에 구동력을 전달하는 프론트 디프레셜과 뒷바퀴의 좌우측에 구동력을 전달하는 리어 디프렌셜을 연결하는 동력 전달축사이에 유체 커플링을 장착하여 앞/뒷바퀴 간의 회전수차를 흡수한다.The biscus coupling method has a rotational aberration between the front / rear wheels by mounting a fluid coupling between the front differential for transmitting the driving force to the left and right sides of the front wheel and the power transmission shaft for connecting the rear differential to the left and right sides of the rear wheel. Absorb it.
센터디프렌셜 방식은 앞바퀴의 좌우측에 구동력을 전달하는 프론트 디프렌셜과, 뒷바퀴의 좌우측에 구동력을 전달하는 리어 디프렌셜사이에 센터디프렌셜을 설치하여 앞/뒷바퀴 간의 회전수차를 흡수한다.Center differential system absorbs rotational aberration between front and rear wheels by installing a center differential between the front differential that transmits the driving force to the left and right sides of the front wheel and the rear differential that transfers the driving force to the left and right sides of the rear wheel. .
그러나 앞바퀴와 뒷바퀴 주행저항 및 노면 상태 등의 차이에 의하여 앞바퀴와 뒷바퀴에 차동력이 발생된다. 이 차동력을 제한하기 위하여 센터디프렌셜 방식은 프론트 디프렌셜과 리어 디프렌셜 사이에 센터디프렌셜과 별도로 차동제한장치를 장착한다.However, differential forces are generated between the front and rear wheels due to differences in front and rear wheel running resistances and road conditions. In order to limit this differential force, the center differential system is equipped with a differential limiter separate from the center differential between the front differential and the rear differential.
한편 파트 타입 4륜 구동방식은 주행패턴 절환장치를 구비하여, 평소에는 2륜구동으로 사용하고, 눈길이나 자갈길 등과 같이 슬립하기 쉬운 도로에서는 4륜구동으로 사용한다.On the other hand, the part-type four-wheel drive system is provided with a driving pattern switching device, usually used as a two-wheel drive, and used as a four-wheel drive on roads that are easy to slip, such as snow or gravel roads.
상기 파트 타입 4륜 구동방식에 사용되는 절환장치는 엔진의 부압을 이용하여 그 작용력을 부가하게 된다.The switching device used in the part-type four-wheel drive method adds the action force by using the negative pressure of the engine.
그러나, 상기한 바와 같은 종래 기술의 자동차의 4륜구동 절환장치는 부압라인의 실링이 파손될 경우에 부압을 유지할 수 없어 전륜에 구동력을 전달하지 못하는 문제점이 있다.However, the four-wheel drive switching device of the conventional vehicle as described above has a problem that can not maintain the negative pressure when the sealing of the negative pressure line is broken, it is unable to transmit the driving force to the front wheels.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 유압에 의하여 구동축을 필요에 따라 일체화하게 됨으로써 기계적으로 용이하게 작동되도록 한 자동차의 4륜구동 절환장치를 제공하는 데 있다.The present invention has been made to solve the above problems, to provide a four-wheel drive switching device for a vehicle that is easy to operate mechanically by integrating the drive shaft by the hydraulic if necessary.

여기서 상기 방향전환밸브(17)는 2방향 2위치밸브이며 전기적인 힘에 의하여 작동되는 솔레노이드임이 바람직하다.Here, the direction switching valve 17 is a two-way two-position valve is preferably a solenoid operated by the electric force.
그리고 상기 방향전환밸브(17)는 하나의 포트가 유압펌프(16)와 연결하게 되며, 다른 하나의 포트가 탱크(18)와 연결하게 되며, 또다른 하나의 포트는 상기 피스톤실린더부재(15)의 한쪽 단부와 연통하여 연결하게 되며, 또다른 하나의 포트는 상기 피스톤실린더부재(15)의 다른쪽 단부와 연통하여 연결하게 된다.And the directional valve 17 is one port is connected to the hydraulic pump 16, the other port is connected to the tank 18, another port is the piston cylinder member 15 It is connected in communication with one end of, and another port is connected in communication with the other end of the piston cylinder member (15).
상기와 같이 구성되는 본 발명에 따른 자동차의 4륜구동 절환장치의 작용을 설명하면 다음과 같다.Referring to the operation of the four-wheel drive switching device of the vehicle according to the present invention configured as described above are as follows.
도 2는 2륜구동으로 차량이 구동되는 상태에서 모드전환스위치(19)가 중립 상태를 유지하고 있어서, 프론트구동축이 분할되어 앞바퀴에 동력이 전달되지 않는 상태이다.2 is a state in which the mode changeover switch 19 is maintained in a neutral state while the vehicle is driven by two-wheel drive, and the front drive shaft is divided so that power is not transmitted to the front wheels.
상기와 같은 상태에서 운전자가 4륜구동측으로 모드전환스위치(19)를 접속하면 유압펌프(16)가 작동하면서 유압이 발생하게 되며, 방향전환밸브(17)에 전기가 인가되어 도시한 바와 같이 작동하게 된다.When the driver connects the mode switching switch 19 to the four-wheel drive in the above state, the hydraulic pump 16 operates to generate hydraulic pressure, and electricity is applied to the direction switching valve 17 to operate as shown. do.
그러면 유압이 실린더피스톤부재(15)의 좌측에 공급되어 실린더피스톤부재(15)의 단부가 돌출되어 전달링크(14)를 도면에서 시계방향으로 회전한다.Then, hydraulic pressure is supplied to the left side of the cylinder piston member 15 so that the end portion of the cylinder piston member 15 protrudes to rotate the transmission link 14 clockwise in the drawing.
상기 전달링크(14)가 회전되면서 회전력단속부재(13)가 좌측으로 이동하게 되어 분할된 구동축(11)이 연동하게 되는 것이다.As the transmission link 14 is rotated, the rotational force control member 13 is moved to the left side so that the divided drive shaft 11 is interlocked.
그래서 변속기로부터의 회전력은 앞바퀴와 뒷바퀴를 용이하게 회전하게 된다.Thus, the torque from the transmission makes it easy to rotate the front and rear wheels.
상기와 같은 4륜구동 상태에서 운전자가 모드전환스위치를 2륜구동 측으로 접속하면 방향전환밸브(17)에 인가되는 전기가 가변되어 좌측으로 작동하게 된다.When the driver connects the mode changeover switch to the two-wheel drive side in the four-wheel drive state as described above, the electricity applied to the direction change valve 17 is changed to operate to the left.
즉 유압펌프(16)으로부터의 유압이 피스톤실린더부재(15)의 우측에 공급되며, 상기 피스톤실린더부재(15)의 좌측에 탱크(18)와 연통하게 된다.That is, the hydraulic pressure from the hydraulic pump 16 is supplied to the right side of the piston cylinder member 15, and communicates with the tank 18 on the left side of the piston cylinder member 15.
그러면 상기 피스톤실린더부재(15)의 단부가 내측으로 삽입되어 전달링크(14)를 도면에서 반시계 방향으로 회전한다.Then, the end of the piston cylinder member 15 is inserted inward to rotate the transmission link 14 counterclockwise in the figure.
그래서 회전력단속부재(13)가 우측으로 이동하여 연동하는 구동축(11)의 분할하게 되어 앞바퀴(4)에는 변속기로부터의 구동력이 전달되지 않게 되며, 이로 인하여 2륜구동 상태가 되는 것이다.Therefore, the rotational force control member 13 is moved to the right to divide the drive shaft 11 to be interlocked, so that the driving force from the transmission is not transmitted to the front wheel 4, thereby resulting in a two-wheel drive state.
이와 같이 본 발명의 자동차의 4륜구동 절환장치는 유압을 이용하여 용이하게 2륜구동 또는 4륜구동을 실현하게 된다.As described above, the four-wheel drive switching device of the vehicle of the present invention realizes two-wheel drive or four-wheel drive easily by using hydraulic pressure.
