Description

차량의 차동제한장치{A Limited Slip Differential of Vehicle}A Limited Slip Differential of Vehicle

본 발명은 차량의 한쪽 바퀴가 슬립(slip)되어 구동력이 손실되는 것을 제한하는 차동제한장치에 관한 것으로, 특히 슬립되는 바퀴측에 자동으로 저항력을 가함으로써 다른 바퀴쪽으로 동력이 전달되도록 된 차량의 차동제한장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a differential limiting device for limiting the loss of driving force by slipping one wheel of a vehicle, and in particular, a differential of a vehicle in which power is transmitted to another wheel by automatically applying a resistance to the slipping wheel side. It is about a limiting device.

일반적으로 차동장치는 디퍼렌셜케이스내에 치합되는 사이드기어 및 피니언기어간의 상호작용에 의해 차량이 주행중 발생하게 되는 좌/우바퀴의 속도 차이를 흡수하여 정상적인 주행상태를 유지하는 기능을 하나, 이러한 자동장치는 차량 주행 중 진흙길이나 눈길등에 바퀴가 빠져 좌우바퀴에 마찰력이 서로 다르게 작용하는 경우 저항이 적은 쪽으로 구동력이 배가되어 전달됨으로써 용이하게 탈출하지 못하는 경우가 종종 발생하게 된다.In general, the differential device absorbs the speed difference between the left and right wheels generated by the vehicle by the interaction between the side gear and the pinion gear engaged in the differential case, and maintains the normal driving state. When wheels fall on muddy roads or snow roads while the vehicle is running, the friction force acts on the left and right wheels, and the driving force is doubled and transmitted to the side with less resistance.

즉, 바퀴로 전달되는 회전력이 빠져있는 바퀴를 통해 새어나가 주행불능 또는 피시테일(Fish Tail: 차량후미 흔들림)현상이 발생하게 되며, 이러한 문제를 해결하기 위해 소형이나 중형차량의 경우에는 차동제한장치(LSD:Limited Slip Differential), 중형이나 대형차량의 경우에는 차동잠금장치(Differential Locking System)가 장착되어 있다.In other words, the driving force that leaks through the wheel that lacks the rotational force transmitted to the wheels may cause inability to drive or fish tail, and in order to solve this problem, the differential limiting device in the case of small or medium vehicles is used. (Limited Slip Differential) (LSD), for medium and large vehicles, it is equipped with a differential locking system.

여기서 상기 차동제한장치는 좌우바퀴에 걸리는 저항차이로 노면저항이 작은 쪽 바퀴가 공전하여 구동력이 감소되었을 때 슬립되면서 공전하고 있는 바퀴의 동력을 감소시키고 반대쪽의 저항이 큰 구동바퀴쪽으로 감소된 만큼의 동력을 더 전달시키는 장치이다.In this case, the differential limiting device is a resistance difference between left and right wheels. When the wheel with smaller road resistance is idle and the driving force is reduced, the differential limiting device decreases the power of the idle wheel and decreases the resistance of the opposite side toward the large driving wheel. It is a device that transmits more power.

그런데 상기 차동제한장치는 장기간 사용시 클러치판의 마찰로 인해 내구력이 저하되고 토크 복원력이 저하될 뿐 아니라, 주행시 클러치판에 지속적으로 마찰력이 작용되기 때문에 연비에 좋지 못한 영향을 주게 된다.By the way, the differential limiting device not only has a low durability and a torque restoring force due to friction of the clutch plate during long term use, but also has an adverse effect on fuel economy because the friction force is continuously applied to the clutch plate during driving.

또한, 상기 차동잠금장치는 운전자의 의지에 따라 수동으로 조작시키도록 되어 있어서 사용이 불편하고, 바퀴가 슬립되는 지역을 탈출한 다음 잠금장치를 즉시 해제시키지 않으면 기어류에 심한 충격이 가해지게 되어 파손되는 경우가 발생될 수 있다는 단점이 있다.In addition, the differential locking device is manually operated according to the driver's will, which is inconvenient to use, and if the wheel is not slipped and then the locking device is not immediately released, the gears are severely damaged and damaged. There is a disadvantage that a case may occur.

이에 본 발명은 상기와 같은 단점을 해결하기 위하여 발명된 것으로, 캠사이드기어와 디퍼렌셜사이드기어 간의 회전수차이가 많이 발생했을 때 이를 감지하여 자동으로 클러치 캠플레이트의 회전을 정지시킴과 동시에 다른쪽 사이드기어로 토오크를 전달시킴으로써 토오크분배를 유도하도록 된 차량의 차동제한장치를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above disadvantages, and when the rotational difference between the camside gear and the differential side gear occurs a lot, it automatically stops the rotation of the clutch cam plate and at the other side. It is an object of the present invention to provide a differential limiting device for a vehicle that is configured to induce torque distribution by transmitting torque to a gear.

도 1은 본 발명에 따른 차동제한장치의 개략적인 구성도로써, 트러스트블럭(1)에 상하방향으로 피니언기어(2)가 설치되고, 이 피니언기어(2)와 치합되는 캠사이드기어(3) 및 디퍼렌셜사이드기어(4)가 구비되며, 상기 캠사이드기어(3)에는 클러치캠플레이트(5)와 토크제한디스크(6) 및 디퍼렌셜클러치(7)가 동축배치되는 한편, 상기 디퍼렌셜사이드기어(4)에도 디퍼렌셜클러치(8)가 동축배치되며, 이들 각각의 부품들은 디퍼렌셜케이스(9)에 내장되도록 되어 있다.1 is a schematic configuration diagram of a differential limiting device according to the present invention, in which a pinion gear 2 is installed in a thrust block 1 in a vertical direction, and is engaged with the pinion gear 2. And a differential side gear (4), wherein the camside gear (3) is coaxially arranged with the clutch cam plate (5), the torque limiting disk (6) and the differential clutch (7), and the differential side gear (4). The differential clutch 8 is also coaxially arranged, and each of these components is arranged in the differential case 9.

그리고, 상기 캠사이드기어(3)와 디퍼렌셜사이드기어(4)의 내주면에 각각 펄스링(10)이 부착되고, 클러치캠플레이트(5)에 복수의 그루우브(11)가 형성되며, 상기 디퍼렌셜케이스(9)의 내주면에는 복수의 볼(12)이 설치되어 있는 바, 이 볼(12)은 디퍼렌셜케이스(9)와 클러치캠플레이트(5)사이에서 롤링되도록 구성되어 있다.In addition, a pulse ring 10 is attached to the inner circumferential surfaces of the camside gear 3 and the differential side gear 4, respectively, and a plurality of grooves 11 are formed on the clutch cam plate 5, and the differential case A plurality of balls 12 are provided on the inner circumferential surface of (9), and the balls 12 are configured to be rolled between the differential case 9 and the clutch cam plate 5.

따라서, 어느 한쪽 바퀴가 슬립되면 사이드기어(3,4)에 설치된 펄스링(10)이 이를 감지하게 되고, 이 감지된 좌/우측 바퀴의 속도차 신호에 의해 볼(12)이 클러치캠플레이트(5)에 형성된 그루우브(11)에 걸려지게 된다.Accordingly, when one of the wheels slips, the pulse ring 10 installed on the side gears 3 and 4 detects this, and the ball 12 is driven by the clutch cam plate by the detected speed difference signal of the left and right wheels. It is caught by the groove 11 formed in 5).

이에 따라 클러치캠플레이트(5)가 순간적으로 로크되게 되고, 계속 회전되려는 캠사이드기어(3)의 원심력에 의해 슬립되는 바퀴쪽으로 클러치캠플레이트(5)가 밀려나가 이탈되게 되며, 이와 동시에 캠사이드기어(3)가 디퍼렌셜클러치(8)를 눌러주게 되는 한편, 이 가압력으로 인해 디퍼렌셜클러치(8)에는 반력이 발생되고 이 반력에 의해 발생된 토오트 복원력이 슬립되는 반대쪽 바퀴로 전달되게 된다.Accordingly, the clutch cam plate 5 is momentarily locked, and the clutch cam plate 5 is pushed out to the wheel which is slipped by the centrifugal force of the cam side gear 3 which is to continue to rotate, and at the same time, the cam side gear While pressing (3) the differential clutch (8), the pressing force causes the differential clutch (8) to generate a reaction force and to transfer the torque restoring force generated by the reaction force to the opposite wheel to slip.

한편, 상기 클러치캠플레이트(5)는 정상주행인 상태에서는 캠사이드기어(3)의 회전에 따라 공전하게 되지만, 이탈시에는 캠사이드기어(3)의 스플라인(13)에물려짐으로써 발생된 복원력으로 캠사이드기어(3)를 회전시켜주게 되는 것이다.On the other hand, the clutch cam plate 5 revolves as the camside gear 3 rotates in the normal driving state. However, when the clutch cam plate 5 is separated, the restoring force generated by being caught by the spline 13 of the camside gear 3 is removed. To rotate the camside gear (3).

이상 설명한 바와 같이 본 발명에 의하면 캠사이드기어간의 회전력차이가 많이 발생했을 때 이를 감지하여 자동으로 한쪽 사이드기어의 회전을 정지시킴과 동시에 다른쪽 사이드기어로 토오크를 전달시킴으로써 토오크분배를 유도함으로써 사용자의 편의성을 향상시키고 내구력이 저하되는 것을 방지하는 잇점이 있다.As described above, according to the present invention, when there are many rotational force differences between the camside gears, it senses this and automatically stops the rotation of one side gear and at the same time transmits torque to the other side gear to induce torque distribution. There is an advantage in improving the convenience and preventing the durability from being lowered.
