Description

자동변속기의 주차조작 안전장치Parking operation safety device of automatic transmission

본 고안은 자동차용 자동변속기의 주차장치부를 개량하여 주행도중에 변속기 레버를 잘못 조작하여 주차위치로 조작시켰을 때 갑작스런 제동이 되지 않도록 한 것으로서, 구체적으로는 주차기어(PARKING SPROKET))의 측면에 유압으로 작동하는 안전판을 설치하여 주행시에는 안전판이 작용하여 고정기어(SPRAG)와 주차기어가 맞물리지 못하도록 한 것이다.The present invention is designed to prevent sudden braking when the transmission lever is incorrectly operated while driving to the parking position by improving the parking lot of the automatic transmission for automobiles, and specifically, hydraulically applied to the side of the parking gear. By installing a working safety plate, the safety plate works when driving so that the fixed gear (SPRAG) and the parking gear cannot be engaged.

종래 자동변속기의 주차브레이크는 도 1에 도시된 바와 같이, 주차기어(1)의 폭과 고정기어(2)의 폭이 동일선상에 위치한 것으로서, 운전자가 자동변속기를 주차브레이크로 변속시키면 상기 주차기어(1)와 고정기어(2)가 서로 맞물리면서 자동차를 정지시키게 되는 것이다.As shown in FIG. 1, the conventional parking brake of the automatic transmission has the same width as that of the parking gear 1 and the width of the fixed gear 2. When the driver shifts the automatic transmission to the parking brake, the parking gear is shifted. (1) and the fixed gear (2) is engaged with each other to stop the car.

그러나, 상기 설명된 바와 같이, 자동변속기에는 주차브레이크 장치가 변속기 레버에 의해 작동되도록 되어 있는데, 이러한 이유로 자동차가 주행도중 운전자나 탑승자의 실수로 변속기 레버를 주차위치로 조작시켰을 경우, 뜻하지 않게 갑자기 차량이 정지되므로 사고가 발생할 위험성이 있었던 것이다.However, as described above, in the automatic transmission, the parking brake device is operated by the transmission lever. For this reason, if the vehicle accidentally operates the transmission lever to the parking position by mistake of a driver or a passenger while driving, It was stopped, so there was a risk of an accident.

이에 따라, 본 고안은 주차장치부를 개량하여 주행도중에는 고정기어가 회전하는 주차기어와 맞물리지 못하도록 함으로써, 안전한 운전을 할 수 있게 하는데 그 목적이 있는 것이다.Accordingly, the present invention is to improve the parking lot to prevent the fixed gear from meshing with the rotating parking gear during driving, the purpose is to enable safe driving.

제1도는 종래 주차 작용부의 단면도.1 is a cross-sectional view of a conventional parking acting portion.

제2도는 본 고안의 단면도.2 is a cross-sectional view of the present invention.

상기 목적 달성을 위한 본 고안 자동변속기 주차조작 안전장치의 일실시예에 따른 구성을 첨부된 도 2에 의거하여 상세히 설명하면 다음과 같다.Referring to the configuration according to an embodiment of the present invention automatic transmission parking operation safety device for achieving the above object in detail as follows.

먼저, 자동변속장치인 고정기어(2)보다 그 폭이 조금 작게 성형되고 그 끝단의 내부 일정위치에 구멍(10a)이 형성된 주차기어(10)와, 상기 주차기어(10)의 회전에 따른 원심력으로 인해 유입되는 유압을 이용하여 차량의 주행 또는 정지상태에 따라 주차브레이크의 작동을 제어하도록 상기 주차기어(10)의 가장자리에 설치된 안전장치부(20)로 구성된다.First, the parking gear 10 is formed to have a smaller width than the fixed gear 2, which is an automatic transmission, and the hole 10a is formed at a predetermined position inside the end thereof, and the centrifugal force according to the rotation of the parking gear 10. FIG. The safety device 20 is installed at the edge of the parking gear 10 to control the operation of the parking brake according to the driving or stop state of the vehicle by using the hydraulic pressure introduced by the.

그리고, 상기 안전장치부(20)에는 차량의 주행시 상기 주차기어(10)의 회전에 따른 원심력으로 인해 흐르는 유압을 안내하는 유압통로(21)와, 상기 유압통로(21)에 의해 안내된 유압을 저장시키는 유압작용실(22)과, 상기 유압작용실(22)에 저장된 유압의 작용에 따라 좌우방향으로 유동하여 주차기어(10)와 고정기어(2)의 맞물림을 제어하는 안전판(23)과, 상기 안전판(23)을 지지하도록 주차기어(10)의 구멍(10a)에 삽입된 지지부(24)와, 차량의 정지시 안전판(23)을 리턴시키도록 상기 지지부(24)에 의해 지지되어 탄성작용하는 스프링(25)을 구성요소로 포함시킨 것으로서, 미설명 부호 26은 유압커버이고, 27은 오일실이다.The safety device 20 includes a hydraulic passage 21 for guiding the hydraulic pressure flowing due to the centrifugal force caused by the rotation of the parking gear 10 when the vehicle is driven, and the hydraulic pressure guided by the hydraulic passage 21. Hydraulic operation chamber 22 to be stored, and the safety plate 23 for controlling the engagement of the parking gear 10 and the fixed gear (2) by flowing in the horizontal direction in accordance with the action of the hydraulic pressure stored in the hydraulic operation chamber 22 and And a support part 24 inserted into the hole 10a of the parking gear 10 to support the safety plate 23, and supported by the support part 24 to return the safety plate 23 when the vehicle is stopped. Including the acting spring 25 as a component, reference numeral 26 is a hydraulic cover, and 27 is an oil chamber.

이러한 구성의 본 고안은, 차량의 정지시 주차기어(10)도 정지되므로 안전장치부(20)에 포함된 안전판(23)은 상기 주차기어(10)의 구멍(10a)에 삽입된 지지부(24)에 의해 지지되고 있는 스프링(25)의 탄성작용에 따라 도 2에 도시된 바와 같이 화살표방향(P)으로 밀림과 동시에 상기 주차기어(10)와 이격되므로서, 자동차의 주차브레이크는 원활하게 작동하게 된다.According to the present invention of the configuration, the parking gear 10 is also stopped when the vehicle is stopped, so the safety plate 23 included in the safety device 20 is supported by the support 24 inserted into the hole 10a of the parking gear 10. As shown in FIG. 2, the parking brake of the vehicle operates smoothly while being spaced apart from the parking gear 10 while being pushed in the direction of the arrow P as shown in FIG. 2. Done.

한편, 상기와 같은 상태에서 차량이 주행하면, 상기 주차기어(10)가 회전을 하게 되고, 상기 주차기어(10)의 회전에 따른 원심력에 의해 유압이 유압통로(21)를 통해 유압커버(26)로 덮여있는 유압작용실(22)로 집중하게 되므로서, 상기 유압 작용실(22)에 집중된 유압에 의해 안전판(23)이 도 2에 도시된 바와 같이 화살표방향(Q)으로 밀림과 동시에 상기 주차기어(10)에 밀착하게 된다.On the other hand, when the vehicle is running in the above state, the parking gear 10 is rotated, the hydraulic pressure by the centrifugal force according to the rotation of the parking gear 10 through the hydraulic passage 21 hydraulic cover (26) By concentrating to the hydraulic pressure chamber 22 covered with the), the safety plate 23 is pushed in the direction of the arrow (Q) as shown in Figure 2 by the hydraulic pressure concentrated in the hydraulic pressure chamber 22 It comes in close contact with the parking gear 10.

따라서, 상기 안전판(23)과 주차기어(10)가 밀착되면, 운전자가 차량의 주행 상태에서 변속기 레버를 주차위치로 조작하더라도 상기 밀착된 안전판(23)에 의해 고정기어(2)가 그 폭이 좁은 주차기어(10)와 맞물리지 못해 차량의 주행상태에서는 주차브레이크가 작동되지 않게 되는 것이다.Therefore, when the safety plate 23 and the parking gear 10 are in close contact with each other, even if the driver operates the transmission lever in the parking position in the driving state of the vehicle, the fixed gear 2 may have a width that is fixed by the close safety plate 23. The parking brake is not operated in the driving state of the vehicle because it is not engaged with the narrow parking gear 10.

이상에서 설명한 바와 같이 본 고안은 원심력에 의해 작용하는 안전장치를 주차기어에 설치함으로써, 자동차가 주행시에는 변속기레버를 주차위치로 조작시킬 수 없게 되는 것이며, 이에 따라 급정지되는 일없이 안전한 주행을 제공할 수 있게 되는 효과가 있는 것이다.As described above, the present invention is to install a safety device acting by the centrifugal force in the parking gear, so that the transmission lever can not be operated to the parking position when the vehicle is running, thereby providing a safe driving without sudden stop. The effect is to be able to.
