Description

자동변속기의 동기치합식 주차시스템Synchronous Matching Parking System of Automatic Transmission

본 발명은 자동차용 자동변속기의 주차시스템에 관한 것으로, 보다 상세하게는 주차의 신뢰성 및 기능을 개선한 자동변속기의 동기치합식 주차시스템에 관한 것이다.The present invention relates to a parking system of an automatic transmission for an automobile, and more particularly, to a synchronized parking system of an automatic transmission having improved parking reliability and function.

모든 자동변속기는 파킹장치를 구비하고 있으며 종래의 파킹장치의 일예는 제1도에 도시한 바와 같이, 미도시된 트랜스미션 아우터레버의 작동에 따라 파킹로드(54)가 직선운동을 하고, 상기 파킹로드(54)의 끝단에 테이퍼 형성된 캠(56)이 이동하면서 파킹폴(parking pawl)(58)을 파킹기어(parking gear 또는 parking lock gear)(60)에 탈착시키게 된다.All automatic transmissions are equipped with a parking device. As an example of the conventional parking device, as shown in FIG. 1, the parking rod 54 linearly moves according to the operation of a transmission outer lever, which is not shown. As the cam 56 tapered at the end of the 54 moves, the parking pawl 58 is detached from the parking gear 60 or the parking gear 60.

즉, 주차하고자 할 때는 캠(56)이 파킹폴(58)을 밀어 이 파킹풀(58)을 파킹기어(60)의 기어이 사이로 들어가게 하여 파킹풀(58)로 하여금 파킹기어(60)의 회전을 방해토록 함으로써 주차작용이 이루어지게 하고, 주차를 해제할 때는 파킹폴(58)을 밀던 캠(56)이 파킹로드(54)의 움직임에 따라 슬라이드되어 파킹폴(58)로 하여금 상기 파킹기어(60)로부터 분리 이탈되도록 함으로써, 파킹기어(60)가 자유롭게 회전될 수 있게 된다.That is, when the parking is to be parked, the cam 56 pushes the parking pole 58 so that the parking pool 58 enters the gear of the parking gear 60 so that the parking pool 58 rotates the parking gear 60. The parking is performed by obstructing, and when the parking is released, the cam 56 pushing the parking pole 58 slides in accordance with the movement of the parking rod 54 to cause the parking pole 58 to move the parking gear 60. By separating and disengaging), the parking gear 60 can be freely rotated.

미설명된 부호 ' 62 ' 는 주차시 충격을 완화하기위한 스프링을 지시한다.Unexplained symbol '62' indicates a spring for mitigating impact when parking.

그러나, 상기 설명한 바와 같이, 종래에는 파킹폴(58)이 파킹기어(60)의 기어이사이에 끼워지는 구조를 하고 있으므로 파킹폴(58)이 파킹기어(60)에 잘들어가지 않아 주차시 충격이 발생하거나, 또는 기어사이에 끼워진 파킹폴(58)이 파킹기어(60)의 이 사이에서 잘빠지지 않아 파킹기어(60)의 주차작용 해제가 부드럽지 못함은 물론 주차작용과 주차해제작용 자체에 문제가 발생할 우려가 있다.However, as described above, the parking pawl 58 is conventionally structured to be sandwiched between the gears of the parking gear 60, so that the parking pawl 58 does not enter the parking gear 60 so that the impact during parking is prevented. The parking pole 58 that occurs or is sandwiched between the gears does not fall well between the teeth of the parking gear 60, so that the parking action of the parking gear 60 is not smooth, as well as the parking action and the parking release action itself. There is a risk of occurrence.

본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 파킹의 신뢰성 및 기능을 개선하여 P레인지 선택시 충격을 줄여 시프트감을 향상시킴은 물론 안전도를 향상시킬 수 있는 자동변속기의 동시치합식 주차시스템을 제공하는 것이다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to improve the reliability and function of the parking to reduce the impact when selecting the P range to improve the sense of shift as well as to improve the safety It is to provide simultaneous parking system of automatic transmission.

The parking system according to the present invention includes: a synchronizer cone fixedly coupled to an output shaft for transmitting rotational force to a wheel of an engine; A synchronizing ring which can be gradually in close contact with the cone portion of the synchronizing cone, and a hub gear coupled to be rotated on the output shaft; A locking sleeve fixed to an inner wall of the transmission case, and a key disposed to be simultaneously coupled to the locking sleeve and the hub gear in a state capable of moving in an output shaft direction; A fork coupled to one side of the key extends at an end thereof and is formed to move the key in the axial direction through the fork, and includes a parking rod that linearly moves according to the operation of the parking lever.

이러한 구성으로 된 본 발명에 의한 파킹시스템은 파킹로드가 파킹레버의 작동에 따라 직선운동을 하면 파킹로드에 고정된 포오크는 키이를 움직여 이 키이로 하여금 슬리버와 결합된 상태하에서 축 방향으로 이동되도록 하고, 상기한 바와 같은 키이가 싱크로나이져링과 치합되면서 이 싱크로나이져링을 싱크로나이져콘의 콘부에 밀착시키면서 결국 싱크로나이져콘과도 결합됨으로써, 출력축과 결합된 상기 싱크로나이져콘을 더 이상 회전시킬 수 없게 한다. 따라서 출력축의 회전 규제로 차량의 주차 상태를 유지시킬 수가 있다.The parking system according to the present invention has a configuration in which the parking rod moves linearly according to the operation of the parking lever and the forks fixed to the parking rod move the keys so that the keys move in the axial direction while being engaged with the slivers. When the key as described above is engaged with the synchronizer ring, the synchronizer ring is brought into close contact with the cone portion of the synchronizer cone and eventually combined with the synchronizer cone, so that the synchronizer cone coupled with the output shaft can no longer be rotated. do. Therefore, the parking state of the vehicle can be maintained by the rotation control of the output shaft.

이하, 상기의 목적을 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention which can realize the above object will be described in more detail with reference to the accompanying drawings.

The synchronizer ring 6 is disposed at the cone portion of the synchronizer cone 4 so that the synchronizer ring 6 can be gradually adhered to the cone portion of the synchronizer cone 4 according to the adhesive force. do. In addition, while the hub gear 8 is coupled to the output shaft 2 in a state capable of revolving, the locking sleeve 12 is fixedly formed on the inner wall of the transmission case 10, and the locking sleeve 12 as described above. And the key 14 in a state in which the key 14 is movable in the output axial direction so that the key 14 can be simultaneously coupled to the hub gear 8.
