Abstract

PURPOSE: Sealing structure for an automatic transmission is provided to reduce the entire length of the automatic transmission, to improve the durability, and to simplify the structure by reducing the number of sealings. CONSTITUTION: A sealing system for an automatic transmission is composed of a shaft(21) formed at the side of a rear cover with the linear outer periphery; a retainer(22) rotated and installed around the shaft; packing(23) fixed between the outer periphery of the shaft and the retainer and made of steel; and sealings(24) mounted in the outer periphery of the packing. Three sealings are arranged at regular intervals, and a hydraulic hole(25) is communicated in the packing and the retainer. The entire length of the automatic transmission is decreased by forming the shaft linearly, and the structure is simplified by reducing the sealing. Lowering of durability is restricted by mounting the steel packing.

Description

자동변속기에 채용된 실링구조{STRUCTURE FOR ADOPTING SEAL RING FOR AN AUTOMATIC TRANSMISSION}Seal structure adopted for automatic transmission {STRUCTURE FOR ADOPTING SEAL RING FOR AN AUTOMATIC TRANSMISSION}

본 발명은 자동변속기에 채용된 실링구조에 관한 것으로서, 보다 상세하게는 자동변속기의 구조를 단순화하기 위한 자동변속기에 채용된 실링구조에 관한 것이다.The present invention relates to a sealing structure employed in the automatic transmission, and more particularly to a sealing structure employed in the automatic transmission for simplifying the structure of the automatic transmission.

수동변속기 장치에서 필요한 클러치(clutch)와 변속기(transmission)의 조작을 자동적으로 행하는 장치가 자동변속기이다. 이 자동변속기는 영어의 머리문자를 인용하여 흔히 AT라고 부른다. 클러치의 역할을 하는 토크 컨버터와 변속을 위한 플래니터리 기어(planetary gear) 등의 작동을 제어하는 습식 다판 클러치와 브레이크(brake)로 되어 있는 것이 보통이다. 이 모든 것을 갖춘 것을 전자동(full automatic) 변속기라 하며, 변속을 수동으로 행하는 것을 반(semi)자동 변속기라 하며, 힘의 매체로서 오일을 사용하는 유체식 외에 벨트와 풀리를 쓰는 벨트식 무단 변속기 들 기계식의 자동변속기도 있다.An automatic transmission is a device that automatically performs clutch and transmission operations required in a manual transmission device. This automatic transmission is often called AT by quoting the English initials. It is common to have a wet multi-plate clutch and brake that controls the operation of the torque converter, which acts as a clutch, and the planetary gear for shifting. All of this is called a full automatic transmission, and a manual shift is called a semi-automatic transmission, and belt-type continuously variable transmissions that use belts and pulleys in addition to fluids that use oil as a medium of force. There is also a mechanical automatic transmission.

도 1에 도시된 바와 같이, 상기한 자동변속기의 리어 커버(rear cover)(10)에서 리버스(reverse) 클러치부의 2개소 공급유로(11)에 알루미늄 소재로 이루어진 샤프트(12)에 4개의 실링(13)이 설치된다. 이때 상기 샤프트(12)는 스텝(step) 형태로 구비된다.As shown in FIG. 1, four seals are formed on a shaft 12 made of aluminum material in two supply passages 11 of a reverse clutch portion in a rear cover 10 of the automatic transmission. 13) is installed. In this case, the shaft 12 is provided in a step form.

그리고 상기와 같이 스텝 형태로 구비된 샤프트(12)에 실링(13)을 설치하는 방법에 있어 4개의 실링(13)이 설치된 중앙 위치에 잔존유압 해제홀(14)을 형성한다.In the method of installing the seal 13 on the shaft 12 provided in the step shape as described above, the remaining hydraulic release holes 14 are formed at the central position where the four seals 13 are installed.

한편, 도 1에서 설명되지 않는 참조부호 15는 리테이너(retainer)이다.On the other hand, reference numeral 15, which is not described in FIG. 1, is a retainer.

그런데, 알루미늄 소재의 습동부에 이물질 침투시 그 내구성이 악화될 우려가 있고, 상기와 같이 실링(13)이 4개가 적용됨으로써 잔존유압 해제홀(14)이 형성되어야 함으로 자동변속기의 전장이 증대된다.However, when the foreign material penetrates the sliding part of the aluminum material, its durability may deteriorate. As the seals 13 are applied as described above, the remaining hydraulic release holes 14 should be formed, thereby increasing the overall length of the automatic transmission. .

또한 실링(13)이 4개가 적용됨으로 불필요하게 그 수가 많이 적용되어 있다.In addition, since four seals 13 are applied, the number of the seals 13 is unnecessarily applied.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 내구성이 악화되는 것을 방지하고, 자동변속기의 전장이 증대되는 것을 방지하며, 실링의 개수가 최소한으로 적용될 수 있도록 한 자동변속기에 채용된 실링구조를 제공하는데 그 목적이 있다.The present invention was created to solve the above problems, and prevents the deterioration in durability, prevents the increase in the overall length of the automatic transmission, and seals employed in the automatic transmission so that the number of seals can be applied to a minimum. The purpose is to provide a structure.
