Therefore, the parking mechanism of the automatic transmission requires a robust mechanism for implementing a stable parking state, and also requires strong durability due to frequent use, and sufficient consideration is given to operating the shift lever as a parking range while driving the vehicle. Should be

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 따른 자동변속기의 파킹기구를 도시한 구성도로서, 자동변속기의 출력측에 연결된 주차기어(1)와; 일단이 동일한 힌지축(3)으로 연결되고 타단은 리턴스프링(5)으로 서로 벌어지도록 연결되어, 상기 주차기어(1)의 원주방향 양측에서 주차기어(1)를 향해 치합되거나 이격될 수 있도록 설치된 한 쌍의 폴레버(7)와; 상기 폴레버(7)의 힌지축(3)이 상기 주차기어(1)의 반경방향을 따라 직선슬라이딩하도록 가이드하는 힌지축가이드(9)와; 상기 힌지축(3)이 주차기어(1)를 향해 이동되면 상기 한 쌍의 폴레버(7)의 외측을 가이드하여, 상기 한 쌍의 폴레버(7)의 내측이 상기 주차기어(1)에 치합되도록 하는 폴레버가이드(11)와; 디텐트플레이트(13)의 회동에 의해 상기 힌지축(3)을 직선슬라이딩시키는 파킹로드(15)를 포함하여 구성된다.1 is a block diagram showing a parking mechanism of an automatic transmission according to the present invention, comprising: a parking gear 1 connected to an output side of the automatic transmission; One end is connected to the same hinge shaft (3) and the other end is connected to be separated from each other by the return spring (5), so as to be engaged or spaced toward the parking gear (1) on both circumferential sides of the parking gear (1). A pair of pole levers 7; A hinge shaft guide (9) for guiding the hinge shaft (3) of the lever (7) to linearly slide along the radial direction of the parking gear (1); When the hinge shaft 3 is moved toward the parking gear 1, the outside of the pair of levers 7 is guided so that the inside of the pair of levers 7 is connected to the parking gear 1. A pole guide 11 to be engaged; And a parking rod 15 for linearly sliding the hinge axis 3 by the rotation of the detent plate 13.
본 실시예에서 상기 힌지축가이드(9)와 상기 폴레버가이드(11)는 변속기케이스의 내부벽면으로 이루어지도록 하였는바, 도시된 바와 같이 힌지축가이드(9)는 상기 힌지축(3)이 상기 파킹로드(15)에 의해 상기 주차기어(1)의 반경방향을 따라 직선이동될 수 있도록 가이드하는 직선형의 긴 홈으로 형성하였으며, 상기 폴레버가이드(11)는 상기 폴레버(7)가 주차기어(1)의 반경방향을 따라 이동함에 따라 폴레버(7)의 외측이 차지할 수 있는 폭을 좁히는 두 경사면으로 형성하였다.In the present embodiment, the hinge shaft guide 9 and the pole guide 11 are made of an inner wall surface of the transmission case. As shown, the hinge shaft guide 9 has the hinge shaft 3 above the hinge shaft guide 9. The parking rod 15 is formed as a straight long groove that guides the linear movement along the radial direction of the parking gear 1, and the pole lever guide 11 has the pole lever 7 as the parking gear. As it moved along the radial direction of (1), it formed in two inclined surfaces which narrow the width which the outer side of the pole lever 7 can occupy.
상기 폴레버(7)의 리턴스프링(5)은 상기 한 쌍의 폴레버(7)가 서로 벌어지는 방향으로 탄성력을 제공하여, 상기 폴레버(7)의 외측이 상기 폴레버가이드(11)에 밀착된 상태를 지속적으로 유지할 수 있도록 하며, 폴레버(7)의 힌지축(3)이 상기 주차기어(1)로부터 멀어지는 방향으로 이동하면 상기 한 쌍의 폴레버(7)를 서로 벌려서 상기 주차기어(1)와의 치합상태를 해제하도록 한다.The return spring 5 of the pole lever 7 provides an elastic force in a direction in which the pair of pole levers 7 are separated from each other, such that the outer side of the pole lever 7 closely adheres to the pole lever guide 11. When the hinge shaft 3 of the pole lever 7 moves in a direction away from the parking gear 1, the pair of pole levers 7 are opened to each other to open the parking gear ( Release the engagement with 1).
상기 폴레버(7)의 힌지축(3)을 직선 이동시키는 상기 파킹로드(15)는 디텐트플레이트(13)에 설치된 고정핀(17)에 슬라이딩 가능한 상태로 끼워지고, 상기 파킹로드(15)와 상기 고정핀(17) 사이에는 완충스프링(19)이 구비되도록 하였다.The parking rod 15 for linearly moving the hinge shaft 3 of the pole lever 7 is fitted in a slidable state to the fixing pin 17 installed on the detent plate 13, and the parking rod 15 And a buffer spring 19 is provided between the fixing pin 17.
따라서, 주행중에 운전자가 변속레버를 주차레인지로 하는 경우에 상기 폴레버(7)가 주차기어(1)에 치합되지 않고, 파킹로드(15)는 상기 고정핀(17)을 슬라이딩하고, 이때 발생되는 충격은 상기 완충스프링(19)이 흡수할 수 있도록 함으로써, 관련 부품들의 파손을 방지할 수 있도록 하였다.Therefore, when the driver shifts the shift lever to the parking range while driving, the pole lever 7 is not engaged with the parking gear 1, and the parking rod 15 slides the fixing pin 17. The shock to be absorbed by the shock absorbing spring 19, it is possible to prevent the breakage of the related parts.
상기한 바와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
운전자가 변속레버를 주차레인지로 하면, 그 조작력은 케이블을 통해 매뉴얼컨트롤레버로 전달되어 상기 디텐트플레이트(13)를 회동시킨다. 상기 디텐트플레이트(13)의 회동에 의해 상기 파킹로드(15)는 상기 폴레버(7)의 힌지축(3)이 상기 주차기어(1)를 향해 직선이동하도록 한다.When the driver sets the shift lever to the parking range, the operation force is transmitted to the manual control lever via a cable to rotate the detent plate 13. By rotating the detent plate 13, the parking rod 15 causes the hinge shaft 3 of the pole lever 7 to move linearly toward the parking gear 1.
따라서, 상기 폴레버(7)의 외측은 상기 폴레버가이드에 의해 점차 좁아지는 경로를 이동하여, 상기 한 쌍의 폴레버(7)는 서로 가까워지는 방향으로 이동되고, 결국 폴레버(7)들의 내측이 상기 주차기어(1)에 함께 치합되는 상태가 되어, 도 2에 도시된 바와 같은 자동변속기의 주차상태를 구현하게 된다.Accordingly, the outer side of the pole lever 7 moves in a path that is gradually narrowed by the pole lever guide, so that the pair of pole levers 7 move in a direction closer to each other, and eventually the poles 7 The inner side is engaged with the parking gear 1, thereby implementing the parking state of the automatic transmission as shown in FIG.
상기와 같이 주차기어(1)에 한 쌍의 폴레버(7)가 한꺼번에 결합됨에 의해 보다 견고하고 안정적인 주차상태가 구현된다.As described above, by combining the pair of levers 7 to the parking gear 1 at once, a more robust and stable parking state is realized.
또한, 상기 주차기능을 구현하는 폴레버(7)의 벌어짐과 좁아짐이 이루어지도록 하는 구성요소들이 상기 파킹로드(15)와, 변속기케이스에 일체로 구비된 힌지축가이드(9) 및 폴레버가이드(11), 리턴스프링(5) 등과 같이 소수이며, 구조상 그 마모가 쉽게 일어나지 않게 되어 있으므로, 높은 내구성이 확보되고 조립 작업성이 향상될 수 있다.In addition, the parking rod 15, the hinge shaft guide (9) and the pole lever guide (integrated with the parking rod 15, the transmission case) are formed so that the components of the opening and narrowing of the pole lever (7) for implementing the parking function ( 11), such as a return spring (5) is a minor number, and because its structure is not easy to wear, high durability can be secured and assembly workability can be improved.
주차레인지에서 해제시에는, 운전자의 변속레버 조작에 의해 상기 디텐트플레이트(13)가 회동되면 상기 폴레버(7)의 힌지축(3)이 주차기어(1)로부터 멀어지고, 그에 따라 상기 한 쌍의 폴레버(7)는 상기 폴레버가이드(11)를 따라 상기 리턴스프링(5)의 힘으로 점차 벌어져서, 상기 주차기어(1)와의 치합상태가 해제되게 되어, 자동변속기의 주차상태가 해제되게 된다.At the time of release from the parking range, when the detent plate 13 is rotated by the driver's shift lever operation, the hinge shaft 3 of the pole lever 7 moves away from the parking gear 1, and thus the The pair of levers 7 are gradually opened along the pole guides 11 by the force of the return spring 5, so that the engagement state with the parking gear 1 is released, thereby releasing the parking state of the automatic transmission. Will be.
이상과 같이 본 발명에 의하면, 한 쌍의 폴레버가 주차기어에 동시에 치합되는 상태를 전환할 수 있도록 된 간단한 메커니즘으로, 강한 내구성과 안정된 작동 신뢰성을 발휘할 수 있다. As described above, according to the present invention, it is a simple mechanism that can switch the state in which the pair of levers are engaged with the parking gear at the same time, it can exhibit a strong durability and stable operation reliability.
