본 고안은 자동차의 자동변속기의 어큐뮤레이터 피스톤(accumulator piston)에 관한 것이다.The present invention relates to an accumulator piston of an automatic transmission of an automobile.

자동차의 자동변속기는 클러치 작용과 트랜스미션의 작용을 자동적으로 하는 것으로, 기어 변속이 필요 없기 때문에 운전의 용이성으로 운전자의 피로가 경감되어 근년에 매우 많이 사용되고 있다.The automatic transmission of the vehicle automatically performs the action of the clutch and the transmission, and since the gear shifting is not necessary, the driver's fatigue is reduced due to the ease of driving, and it has been used in recent years.

자동변속기는 변속과정중 자동적으로 기어비가 변화하게 되는데, 즉 엔진의 회전수가 기어비의 변화에 따라 변화하게 되고 엔진의 관성력의 변화를 초래하게 된다.In the automatic transmission, the gear ratio is automatically changed during the shifting process, that is, the rotational speed of the engine is changed according to the gear ratio, and the inertia force of the engine is changed.

이러한 관성력의 변동이 토르크의 변동으로 나타나서 충격(shock) 이 발생되어 운전자가 변속시 충격을 느끼게 된다.This change in the inertia force appears as a change in torque, the shock (shock) is generated, the driver feels the shock when shifting.

종래 장치는 제1도에 나타낸 바와같이, 시일(11)을 갖는 어큐뮤레이터 피스톤(10)의 일측에는 작동압이 작용하는 실린더(40)와 라인압이 작용하는 유압실(30)이 형성되어 있다. 상기 유압실(30)에는 스프링(20)이 어큐뮤레이터 피스톤(10)에 탄성력있게 지지되어 있다.In the conventional apparatus, as shown in FIG. 1, a cylinder 40 to which an operating pressure acts and a hydraulic chamber 30 to which a line pressure acts are formed at one side of the accumulator piston 10 having a seal 11. have. A spring 20 is elastically supported by the accumulator piston 10 in the hydraulic chamber 30.

그러나, 이러한 종래 장치는, 작동압이 작용하는 실린더(40)에 유압의 충격을 완화할 수 있는 장치가 없어서 변속시 심한 충격이 발생하는 문제점이 있었다.However, such a conventional apparatus has a problem that a severe shock occurs during shifting because there is no device that can alleviate the impact of hydraulic pressure in the cylinder 40 to which the working pressure acts.

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 작동압이 작용하는 어큐뮤레이터 피스톤내에 유압조절판을 부설하여 어큐뮤레이터 피스톤을 제공하는데 있다.An object of the present invention is to solve the conventional problems as described above, to provide an accumulator piston by installing a hydraulic control plate in the accumulator piston to which the working pressure acts.

이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

본 고안 장치는 제2도에 나타낸 바와같이, 시일(110)을 갖는 어큐뮤레이터 피스톤(100)의 일측에는 작동압이 작용하는 실린더(40)와 라인압이 작용하며 작동 스피링(20)이 어큐뮤레이터 피스톤(100)에 탄성력 있게 지지되는 유압실(30)로 형성된 것에 있어서, 상기 실린더(40)측 내부에 스토퍼(140)에 의하여 행정거리가 한정되고 완충스프링(130)이 탄성력있게 지지되는 유압조절판(120)을 주설한 자동변속기의 어큐뮤레이터 피스톤(accumulator piston)을 그 기술적 구성상의 특징으로 한다.In the device of the present invention, as shown in FIG. 2, one side of the accumulator piston 100 having the seal 110 acts on the cylinder 40 and the line pressure to which the working pressure is applied, and the operating spring 20 is applied. In the hydraulic chamber 30 is elastically supported on the accumulator piston 100, the stroke distance is limited by the stopper 140 inside the cylinder 40 side, the buffer spring 130 is supported elastically The accumulator piston of the automatic transmission in which the hydraulic control plate 120 is installed is characterized by its technical configuration.

이러한 본 고안장치는 제2도에 나타낸 바와 같이, 작동압이 실린더(40)에 급격히 작용하면 유압조절판(120)이 완충스프링(130)의 스프링력을 이겨서 도면에서 우측으로 이동시킨다. 다라서 유압이 작용하는 전체 면적이 늘어나게 되므로 유압 상승을 흡수할 수 있게 된다.In the device of the present invention, as shown in FIG. 2, when the operating pressure acts rapidly on the cylinder 40, the hydraulic control plate 120 overcomes the spring force of the shock absorbing spring 130 and moves to the right in the drawing. As a result, the total area in which the hydraulic pressure acts increases, thus absorbing the hydraulic pressure increase.

이상에서 살펴 본 바와 같이, 본 고안 장치는 작동압이 작용하는 어큐뮤레이터 피스톤내에 유압조절판을 부설하여 자동변속기의 변속초기에 유압충격을 흡수하도록하는 유용한 것이다.As described above, the device of the present invention is useful to absorb the hydraulic shock in the initial transmission of the automatic transmission by installing a hydraulic control plate in the accumulator piston under the operating pressure.
