본 고안은 자동차의 기어변속시에 5단 변속상태에서 바로 후진변속이 이루어지지 못하도록 이를 방지하여 주는 자동차 변속기의 후진오조작 방지장치에 관한 것이다.The present invention relates to a reverse misoperation preventing device for a vehicle transmission that prevents the reverse shift from being performed immediately in a five-speed shift state during a gear shift of an automobile.

근자에는 대부분의 자동차가 종래와 같은 4단 기어를 사용하지 않고 거의 5단 기어를 채택 사용하고 있는 실정이다.In recent years, most automobiles do not use the conventional four-speed gears and use almost five-speed gears.

따라서 5단기어 변속의 위치와 후진기어 변속의 위치가 보통 일직선상으로 한곳에 위치하게 되는데, 이때 5단기어의 상태에서 바로 후진기어의 상태로 기어가 변속되는 경우에는 자동차의 파손 및 고장을 일으키는 원인이 되기 때문에 이들 5단과 후진 변속기어 사이에는 5단기어 위치로 부터 후진기어 위치로 변속되는 것을 방지하기 위한 장치들을 설치하여 후진기어는 항시 중립의 상태에서만 기어가 변속될 수 있도록 하고 있다.Therefore, the position of 5 gear shift and the position of reverse gear shift are generally located in one straight line.In this case, if the gear is shifted from the 5 gear to the reverse gear, it may cause damage and failure of the car. Because of this, devices are installed between the fifth gear and the reverse gear to prevent shifting from the five gear position to the reverse gear position so that the gear can be shifted only in the neutral state at all times.

종래에는 이와같은 변속기 후진오조작 방지장치가 첨부도면 제5도 및 제6도에 도시한 바와같은 형태로서, 변속레버(1)를 가이드하는 가이드플레이트(10)의 5단과 후진위치 사이에 스프링(11)의 탄력을 받으며 회전 가능한 작동편(12)을 설치하여, 변속레버(1)가 중립위치로 부터 5단기어 또는 후진기어측으로 변속이 이루어지는 경우에는, 변속레버(1)가 가이드 플레이트(10)에 설치된 작동편(12)을 밀면서 5단기어나 후진기어 변속의 위치로 이동하고, 만일 변속레버(1)가 5단기어에 위치한 상태에서 후진기어 측으로 조작을 실시하는 경우에는 작동편(12)이 실선의 위치에서 일점쇄선의 위치로 변환되면서 후진기어 변속위치를 막아줌에 따라 5단기어로부터 후진기어축으로의 변속레버(1)의 이동을 막아주게 된다.Conventionally, such a transmission reverse operation prevention device is formed as shown in FIGS. 5 and 6 of the accompanying drawings, and includes a spring (5) between the retracted position and the fifth stage of the guide plate 10 for guiding the shift lever 1. 11) When the shifting lever 1 is shifted from the neutral position to the 5th gear or the reverse gear side by installing the rotatable working piece 12 receiving the elasticity of the 11), the shifting lever 1 is the guide plate 10. 5) move to the position of five-speed gear or reverse gear shifting by pushing the operating piece 12 installed in the), and if the shift lever 1 is operated to the reverse gear side when the shifting lever 1 is located at the five-speed gear, The shift of the shift lever 1 from the 5th gear to the reverse gear shaft is prevented by preventing the reverse gear shifting position while converting from the solid line position to the one-dot chain line position.

그러나 상기한 바와같이 가이드 플레이트상에 회전 가능한 작동편을 설치하여 변속기 후진 오조작을 방지하도록 된것은, 작동편 설치를 위한 별도의 공간을 확보해 주어야만 되었기 때문에 설계상의 많은 어려움이 수반되었고, 평면가공작업과 함께 조립에 따른 부가적인 많은 부품이 소요되어 작업의 복잡함과 함께 원가상승의 요인이 되는 문제점이 작용하였다.However, to prevent the reverse operation of the transmission by installing a rotatable operating piece on the guide plate as described above, it was necessary to secure a separate space for the installation of the moving piece involved a lot of design difficulties, planar processing In addition to the work, many additional parts were required due to the assembly, which contributed to the complexity of the work and the cost increase.

본 고안은 이와같은 종래의 문제점을 감안하여 안출한 것으로서, 별도의 공간확보가 필요치 않는 변속엔드상에 변속기 후진 오조작을 방지하기 위한 설비를 간단하게 설치할 수 있도록 한 것이다.The present invention has been made in view of such a conventional problem, it is to make it easy to install a facility for preventing transmission reverse operation on the transmission end that does not require a separate space.

상기 목적을 달성하기 위한 본 고안에 따르면, 변속레버(1)와 연동하는 변속엔드(2)의 후진변속부 위치에 반달홈(2a)을 형성하고, 상기 반달홈(2a)상에 변속레버(1)와 접촉하는 반달형 게이트편(3)을 스프링(4)과 함께 수평 이동 가능하게 설치하여서 된것이다.According to the present invention for achieving the above object, a half moon groove (2a) is formed at the position of the reverse shift portion of the shift end (2) in conjunction with the shift lever (1), the shift lever (2) on the half moon groove (2a) The vandal gate piece 3 in contact with 1) is installed with the spring 4 so as to be movable horizontally.

이와같이 된 본 고안을 첨부도면과 함께 더욱 상세히 설명하면 다음이 같다.When the present invention is described in more detail with the accompanying drawings as follows.

제1도는 본 고안의 진체적인 구성도로서, 5단기어 변속위치와 일직선을 이루는 후진변속의 변속엔드(2)측에 수평이동이 가능하도록 게이트편(3)을 스프링(4)과 함께 설치하여 변속레버(1)와 접촉하는 게이트편(3)이 스프링(4)을 밀거나 또는 스프링(4)의 탄성력에 의하여 게이트편(3)의 복원이 이루어 지도록 배치되어 있으며, 제1도상의 변속레버(1)는 현재 중립 상태에 위치하고 있다.1 is a schematic block diagram of the present invention, in which the gate piece 3 is installed together with the spring 4 to enable horizontal movement on the shift end 2 side of the reverse shift that is in line with the five-speed gear shift position. The gate piece 3 in contact with the shift lever 1 is arranged to push the spring 4 or to restore the gate piece 3 by the elastic force of the spring 4, and the shift lever shown in FIG. (1) is currently in a neutral state.

이와같은 상태에서 직접적인 후진변속을 실시하기 위하여 변속 레버(1)를 후진위치로 이동시켜 주게 되면, 제2도와 같이 돌출되어 있는 게이트편(3)을 변속레버(1)가 화살표 방향으로 밀면서 스프링(4)을 압축시켜 제3도와 같이 게이트편(3)을 이동시킴에 따라 후진변속측의 개방이 이루어져 변속레버(1)의 후진변속이 가능해지게 된다.When the shift lever 1 is moved to the reverse position in order to perform the reverse shift in this state, the shift lever 1 pushes the protruding gate piece 3 in the direction of the arrow as shown in FIG. 4) by compressing and moving the gate piece 3 as shown in FIG. 3, the reverse shift side is opened, so that the reverse shift of the shift lever 1 is possible.

이와같은 후진변속상태에서 다시 변속레버(1)를 중립위치로 이동시켜 주게 되면 스프링(4)을 압축하며 이동되었던 게이트편(3)이 스프링(4)의 복원력에 의하여 제2도와 같은 원상태를 유지하게 된다.When the shift lever 1 is moved to the neutral position in this reverse shift state, the spring 4 is compressed and the moved gate piece 3 maintains its original state as shown in FIG. 2 by the restoring force of the spring 4. Done.

따라서 상기와 같은 과정의 후진변속시나 5단변속시에는 변속 레버(1)의 이동에 따라 게이트편(3)이 이와 접촉하여 수평이동됨에 따라 변속레버(1)를 중립위치 상태로 부터 후진변속 또는 5단변속 위치로 선택 이동할수 있게 된다.Therefore, when the reverse shift or the five-speed shift in the above process, as the gate piece 3 is in contact with and horizontally moved in accordance with the shift lever 1, the shift lever 1 is shifted from the neutral position to the reverse shift or Selective movement to the five-speed position is possible.

그러나 5단변속 상태에서 바로 후진변속을 실시하는 경우에는, 5단변속을 실시하기 위하여 게이트편(3)을 이동시켜 변속레버(1)를 5단변속위치로 이동시킨 상태에서는 게이트편(3)과 변속레버(1)와의 접촉이 해제되어 게이트편(3)이 스프링(4)의 탄성력을 받아 원상태로 복원되어 있기 때문에 제4도와 같이 게이트편(3)의 걸림작용에 의하여 변속레버(1)의 후진변속이 불가능하게 되는 것이다.However, in the case where the reverse shift is performed immediately in the five-speed shift state, the gate piece 3 is moved in the state in which the gate piece 3 is moved to shift the shift lever 1 to the five-speed shift position to perform the five-speed shift. Contact with the shift lever 1 is released and the gate piece 3 is restored to its original state by receiving the elastic force of the spring 4, so that the shift lever 1 is engaged by the gate piece 3 as shown in FIG. The reverse shift is impossible.

이와같이 본 고안은 변속엔드상에 수평 이동가능한 게이트편을 설치하여 자동차의 변속이 5단변속후 바로 후진변속이 이루어지는 것을 막아주게 되므로, 변속엔드부의 충분한 유휴공간을 활용함에 따라 종래장치와 같이 별도의 공간확보를 고려할 필요가 없어 설계가 간편하게 이루어지고, 또한 조립 및 보수작업등을 용이하게 실시할 수 있게 되는 효과를 갖는다.As such, the present invention prevents the shift of the vehicle from being shifted immediately after the five-speed shift by installing a horizontally movable gate piece on the shift end, so as to utilize a sufficient idle space of the shift end part as in a conventional apparatus There is no need to consider the space to secure the design is made easily, and has the effect that can be easily performed assembly and maintenance work.
