Description
본 고안은 자동변속기용 스틱 방지 N-D 조절밸브에 관한 것으로서 구체적으로 자동차 자동변속기의 유압제어시스템에 구비된 N-D 조절밸브로서, 슬리브와 밸브와의 스틱현상 발생을 방지할 수 있는 N-D 조절밸브에 관한 것이다.The present invention relates to a stick prevention ND control valve for an automatic transmission, and more particularly, to an ND control valve provided in a hydraulic control system of an automatic transmission, and an ND control valve capable of preventing stick phenomenon between a sleeve and a valve. .
자동차의 자동변속기는 운전자의 가속페달 조작만으로 차량의 주행속도를 가감할 수 있는 변속기로서, 토크 컨버터와 유성기어의 조합에 의하여 유압을 조정하여 작동된다. 이러한 자동변속기에는 각종 클러치와 브레이크를 제어하기 위하여, 레귤레이터 밸브, 댐퍼 클러치 밸브, 매뉴얼 밸브, 쉬프트 제어 밸브등으로 이루어지는 유압제어 시스템에 구비되어 있다.The automatic transmission of a vehicle is a transmission that can adjust the driving speed of the vehicle only by operating the accelerator pedal, and is operated by adjusting the hydraulic pressure by a combination of a torque converter and a planetary gear. In order to control various clutches and brakes, such automatic transmissions are provided in a hydraulic control system including a regulator valve, a damper clutch valve, a manual valve, a shift control valve, and the like.
자동변속기의 유압제어 시스템에는 특히, 변속기의 선택레버가 중립(N)에서 주행(D) 위치로 변할 때 충격을 방지하기 위하여 N-D 조절밸브(Neutral-drive position control valve)가 구비되는데, 제1도에는 N-D 조절밸브의 개략도가 도시되어 있다. N-D 조절밸브는 매뉴얼 밸브(도시되지 않음)에 의한 라인압력에 의하여 각 랜드부간의 면적 차이에 의하여 해당 포트를 개폐하므로써 변속을 위한 유압을 전달하게 된다.The hydraulic control system of the automatic transmission is equipped with an ND-neutral-drive position control valve, in particular to prevent shock when the selector lever of the transmission changes from the neutral (N) to the traveling (D) position. A schematic diagram of the ND control valve is shown. The N-D control valve transmits the hydraulic pressure for shifting by opening and closing the corresponding port by the area difference between each land part by the line pressure by the manual valve (not shown).
상기의 N-D 조절밸브에 있어서 문제점으로 지적되는 것은, 도면에 도시된 바와 같이, 밸브의 단부(101)가 일체형으로 이루어져 있어 배출측에 위치한 슬리브(Sleve:102)와의 사이에서 스틱(stick) 현상이 발생한다는 것이다. 이러한 N-D 조절밸브와 슬리브와의 사이에서 발생하는 스틱현상은 결국 N-D 조절밸브의 작동불량을 초래하고 결국에는 전체 자동변속기의 성능을 저하시키게 된다. 따라서 지금까지 자동변속기 기술분야에서는 N-D 조절밸브에 있어서 밸브와 슬리브 사이의 스틱현상을 줄이거나 없앨 수 있는 기술이 요망되어 왔다.The problem with the ND control valve is that, as shown in the figure, the end portion of the valve 101 is integrally formed so that a stick phenomenon occurs between the sleeve 102 positioned on the discharge side. It happens. The stick phenomenon occurring between the N-D control valve and the sleeve eventually leads to a malfunction of the N-D control valve and eventually degrades the performance of the entire automatic transmission. Therefore, until now, in the field of automatic transmission technology, a technique for reducing or eliminating the stick phenomenon between the valve and the sleeve in the N-D control valve has been desired.
본 고안은, 상기한 바와 같은 필요에 의하여 개발된 것으로, 자동변속기의 유압제어 시스템에 구비된 N-D 조절밸브에 있어서, 밸브와 슬리브간에 스틱현상이 발생하지 않도록 구성된 N-D 조절밸브를 제공함을 기본적인 목적으로 한다.The present invention, which was developed in accordance with the above-described needs, in the ND control valve provided in the hydraulic control system of an automatic transmission, provides a ND control valve configured so that stick phenomenon does not occur between the valve and the sleeve. do.
상기한 본 고안의 목적을 달성하기 위하여, 본 고안에서는 밸브의 단부는 자유단부로 구성하고, 상기 자유단부에는 밸브의 이동을 위한 스프링이 장착되고, 스프링과 슬리브간의 연통통로에는 플러그가 장착되는 것을 특징으로 하는 N-D 조절밸브가 제공된다.In order to achieve the object of the present invention, in the present invention, the end of the valve is configured as a free end, the free end is equipped with a spring for the movement of the valve, the communication passage between the spring and the sleeve is that the plug is mounted An ND control valve is provided.

이하, 첨부도면을 참조하여 본 고안의 구성 및 본 고안에 따른 일 실시예의 구성을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention and the configuration of an embodiment according to the present invention.
제2도는 본 고안에 N-D 조절밸브의 구성이 개략적으로 도시되어 있다. 도면부호 1은 밸브 본체로서, 배출구(2)와 연통된 단부는 자유단부(3)로 구성되어 있다. 상기 자유단부(3)에는 스프링(4)이 장착되어 있는데, 상기 스프링(4)은 리어클러치(도시되지 않음)로의 통로(5)를 개폐하기 위하여 자유단부(3)에 탄성력을 가하게 된다.Figure 2 schematically shows the configuration of the N-D control valve in the present invention. Reference numeral 1 denotes a valve body, and an end portion communicating with the discharge port 2 is constituted by a free end portion 3. The free end 3 is equipped with a spring 4 which applies an elastic force to the free end 3 to open and close the passage 5 to the rear clutch (not shown).
매뉴얼 밸브(도시되지 않음)으로부터의 유압이 공급디는 통로(6)에는 슬리브(7)가 위치하며, 상기 슬리브(7)와 밸브 본체(1)의 자유단부(2)와의 사이에 형성된 통로에는 플러그(plug:8)가 장착된다. 즉, 종래 기술에서의 일체로 이루어진 밸브 단부의 기능을 플러그로서 대신하게 되는 것이다.A sleeve 7 is positioned in a passage 6 through which hydraulic pressure from a manual valve (not shown) is provided, and a passage formed between the sleeve 7 and the free end 2 of the valve body 1 is provided. A plug 8 is mounted. That is, the plug replaces the function of an integral valve end in the prior art.
따라서 N-D 조절밸브의 작동중에 열팽창 또는 마찰열 등에 의하여 밸브본체의 단부가 슬리브와 달라붙지 않게 된다.Therefore, the end of the valve body does not stick to the sleeve due to thermal expansion or frictional heat during operation of the N-D control valve.
이상에서 살펴본 바와 같이, 본 고안에서는 밸브 본체(1)의 단부를 일부 제거하여 자유단으로 구성하고 슬리브와 밸브 본체 사이의 유체 통로에는 플러그를 장착하므로써 N-D 조절밸브의 작동중에 열팽창 또는 마찰열 등에 의하여 밸브 본체의 단부가 슬리브와 달라붙는 스틱 현상의 발생을 방지할 수 있게 되며, 그에 따라 자동변속기의 작동 안정성도 향상된다.As described above, in the present invention, a part of the end of the valve body 1 is removed to form a free end, and a plug is installed in the fluid passage between the sleeve and the valve body so that the valve may be opened due to thermal expansion or frictional heat during operation of the ND control valve. It is possible to prevent the occurrence of the stick phenomenon that the end of the body sticks to the sleeve, thereby improving the operational stability of the automatic transmission.
본 고안은 실용신안등록청구의 범위에 기재되어 있는 바와 같이 자동변속기의 N-D 조절밸브 및 그 일실시예에 관해서만 설명하였으나, 이에 한정되지 아니하며 당업자라면 본 고안의 기술적사상을 벗어나지 않는 범위내에서 다양한 응용과 변형이 가능할 것이다.The present invention has been described only with respect to the ND control valve and one embodiment of the automatic transmission as described in the scope of the utility model registration request, but is not limited to this and those skilled in the art will be various within the scope without departing from the technical spirit of the present invention Applications and variations will be possible.
