Description
본 고안은 자동변속기용 클러치 어셈블리에 관한 것으로서, 보다 상세하게는 고속 회전시에 잔유압에 의해 발생되는 변속쇼크를 방지하고, 제동력에 의한 동력 손실을 감소시키도록 된 자동변속기용 클러치 어셈블리에 관한 것이다.The present invention relates to a clutch assembly for an automatic transmission, and more particularly, to a clutch assembly for an automatic transmission to prevent shift shock caused by residual oil pressure at high speed and to reduce power loss due to braking force. .
상기 동력전달장치는 엔진에서 발생된 동력을 구동바퀴에 전달하기 위한 장치로 클러치, 변속기, 추진축, 종감속기어, 차동장치, 액슬 샤프트 등으로 구성된다.The power transmission device includes a clutch, a transmission, a propulsion shaft, a reduction gear, a differential, an axle shaft, and the like for transmitting power generated from an engine to a driving wheel.
상기 자동차의 클러치는 플라이휘일과 변속기의 입력축 사이에 설치되어 변속기로 전달되는 기관의 동력을 필요에 따라 단속하는 일을 하며, 기관을 시동할 때 또는 변속기의 기어를 변속할 때에는 기관과의 연결을 끊고, 발진할 때에는 기관의 동력을 서서히 연결하는 일을 한다.The clutch of the vehicle is installed between the flywheel and the input shaft of the transmission to regulate the power of the engine transmitted to the transmission as necessary, and when connecting the engine when starting the engine or shifting the gear of the transmission. When disconnecting and oscillating, the engine is gradually connected to power.
이와 같이 동력을 끊거나 또는 연결하기 위해서 클러치는 유압에 의해 구동판과 피구동판을 마찰 또는 해방시켜 동력의 전달하거나 끊을 수 있도록 되어 있다.In order to cut off or connect the power as described above, the clutch is configured to be able to transmit or break the power by rubbing or releasing the driving plate and the driven plate by hydraulic pressure.
다판클러치를 도시한 도 1 을 참조하여 상세히 설명하면, 리테이너(10)의 일측에는 오일통로(12)가 형성되어 있고, 상기 리테이너(10)의 내측에는 상기 오일통로(12)에 유입되는 유압에 의해 전후방향으로 이동가능하도록 피스톤(20)이 설치되어 있으며, 상기 피스톤(20)에는 체크볼(30)이 설치되어 있다.Referring to Figure 1 showing the multi-plate clutch in detail, an oil passage 12 is formed on one side of the retainer 10, the inner side of the retainer 10 to the hydraulic pressure flowing into the oil passage 12 The piston 20 is provided so as to be movable in the front-rear direction, and the check ball 30 is installed in the piston 20.
한편, 유압이 드레인되면 상기 피스톤(20)을 원위치로 복원시키도록 리턴스프링(40)이 설치되어 있는데, 상기 리턴스프링(40)은 리테이너(10)에 고정된 스냅링(50)에 의해 고정되어 있다.On the other hand, when the hydraulic pressure is drained, the return spring 40 is installed to restore the piston 20 to its original position. The return spring 40 is fixed by the snap ring 50 fixed to the retainer 10. .
여기서, 상기 피스톤(20)에 설치된 체크볼(30)은 유압을 해방시킬때 유압실내를 대기압과 동일하도록 함으로써 유압의 배출을 돕는 역할을 하는 것이다.Here, the check ball 30 installed in the piston 20 serves to help the discharge of the hydraulic pressure by making the hydraulic chamber equal to atmospheric pressure when releasing the hydraulic pressure.
그러나, 상기 체크볼(30)은 피스톤(20)의 중앙부에 설치된 구조이므로, 고속회전중 유압을 배출할 때에 원심력에 의한 영향으로 체크볼(30)의 외측방향, 즉 리테이너(10)가 형성하는 유압실 내부의 외측방향으로 잔유압이 발생되어 변속 쇼크가 발생되고, 구동판 및 피구동판의 마찰에 의한 동력 손실을 발생시킨다는 문제점이 있었다.However, since the check ball 30 has a structure installed in the center of the piston 20, when the hydraulic pressure is discharged during the high speed rotation, the check ball 30 is formed in the outer direction of the check ball 30, that is, the retainer 10 is formed. There was a problem in that residual oil pressure was generated in the hydraulic chamber in an outward direction to generate a shift shock, thereby causing power loss due to friction between the driving plate and the driven plate.
본 고안은 상기와 같은 문제점을 감안하여 안출된 것으로서, 본 고안의 목적은 리테이너에 체크볼을 설치함으로써 고속 회전시 발생되는 잔유압에 의한 변속쇼크를 저감하고, 제동력에 의한 동력손실을 감소시키는데 있다.The present invention was devised in view of the above problems, and an object of the present invention is to reduce the shift shock caused by residual hydraulic pressure generated at high speed by reducing the power loss due to braking force. .

상기한 목적을 실현하기 위하여 본 고안은 유압에 의해 작동되도록 오일통로가 형성된 리테이너와, 상기 리테이너의 내부에 설치된 피스톤과, 상기 피스톤의 동작에 따라 마찰 또는 해방되도록 연동되는 구동판과, 상기 피스톤을 원위치로 복원시키도록 상기 상기 리테이너에 설치된 리텐스프링을 포함하는 자동변속기용 클러치 어셈블리에 있어서, 상기 리테이너의 일측에는 체크볼이 설치된 것을 특징으로 하는 자동변속기용 클러치 어셈블리를 제공한다.In order to achieve the above object, the present invention provides a retainer in which an oil passage is formed to operate by hydraulic pressure, a piston installed in the retainer, a driving plate interlocked so as to be friction or released according to the operation of the piston, and the piston. In the clutch assembly for an automatic transmission comprising a retaining spring installed in the retainer to restore to the original position, there is provided a clutch assembly for an automatic transmission, characterized in that a check ball is installed on one side of the retainer.
이하, 첨부 도면을 참조하면서 당업자가 용이하게 실시할 수 있을 정도의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 실시예에 의한 자동변속기용 클러치 어셈블리는 도 2 에 도시된 바와 같이 리테이너(10)의 일측에는 오일통로(12)가 형성되어 있고, 상기 리테이너(10)의 내부에는 상기 오일통로(12)에 유입되는 유압에 의해 전후방향으로 이동가능하도록 피스톤(20)이 설치되어 있다.In the clutch assembly for an automatic transmission according to the present embodiment, as shown in FIG. 2, an oil passage 12 is formed at one side of the retainer 10, and the oil passage 12 is formed inside the retainer 10. The piston 20 is provided to be movable in the front-rear direction by the oil pressure which flows in.
그리고, 유압이 드레인되면 상기 피스톤(20)을 원위치로 복원시키도록 리턴스프링(40)이 설치되어 있는데, 상기 리턴스프링(40)은 리테이너(10)에 고정된 스냅링(50)에 의해 고정되어 있다.When the hydraulic pressure is drained, a return spring 40 is installed to restore the piston 20 to its original position. The return spring 40 is fixed by a snap ring 50 fixed to the retainer 10. .
여기서, 상기 리테이너(10)의 일측에는 체크볼(30)이 설치되어 있는 바, 상기 체크볼(30)은 유압을 해방시킬 때 유압실 내부의 압력과 대기압이 동일하게 함으로써 유압의 배출을 돕는 역할을 한다.Here, the check ball 30 is provided on one side of the retainer 10, the check ball 30 serves to help the discharge of the hydraulic pressure by the same pressure and atmospheric pressure inside the hydraulic chamber when releasing the hydraulic pressure Do it.
또한, 상기 체크볼(30)은 리테이너(10)의 내부 즉, 유압실의 외측방향에 치우친 위치에 설치되어 있으므로, 고속 회전시에 유압을 드레인 시키더라도 원심력에 의한 잔유압이 발생되지 않는다.In addition, since the check ball 30 is installed in the retainer 10, that is, the position biased to the outer direction of the hydraulic chamber, the residual oil pressure due to the centrifugal force is not generated even when the hydraulic pressure is drained at the high speed rotation.
상기와 같이 구성된 본 고안에 의한 자동변속기용 클러치 어셈블리에 의하면 클러치가 고속회전시에 유압을 드레인시키더라도 유압실 내부에 잔유압이 발생되지 않게 되는 구조이므로, 잔유압에 의한 변속쇼크가 방지됨과 아울러 제동력에 의한 동력손실을 저감시킨다는 효과가 있다.According to the clutch assembly for an automatic transmission according to the present invention configured as described above, the residual oil pressure is not generated in the hydraulic chamber even when the clutch drains the hydraulic pressure at a high speed rotation, thereby preventing shift shock caused by the residual oil pressure. There is an effect of reducing the power loss by the braking force.
상기에서 설명된 본 실시예는 단지 예시에 불과한 것이고 이에 한정되는 것은 아니다. 또한, 본 고안이 속한 분야의 통상의 지식을 가진 자는 용이하게 변형실시 할 수 있으나 , 첨부된 청구범위에서 알 수 있는 바와 같이, 이러한 변형된 실시는 본 고안의 범위에 속한다는 것을 당업자는 용이하게 파악할 수 있을 것이다.The embodiment described above is merely illustrative and is not limited thereto. In addition, one of ordinary skill in the art to which the present invention pertains may be easily modified, but as can be seen in the appended claims, those skilled in the art will readily appreciate that such modified implementation is within the scope of the present invention. I can figure it out.
