Abstract

A shifting mechanism of an intermediate transmission is provided to simplify structure of a link by reducing the number of shift levers, to cut down material cost by reducing the number of parts, and to prevent accidents by restricting wrong operation of the shift lever. A shifting mechanism of an intermediate transmission(20) includes first and second rails(21,22) installed in parallel with the intermediate transmission mounted in a four-wheel drive vehicle to fix a shift fork, a shift link(23) simultaneously connected to the first and second rails to interlock the first and second rails, a rod(24) connected and installed to an end of the shift link, and a shift lever(25) connected to an end of the rod to operate the rod. The first rail is mounted to shift from a 4x2 range into a 4x4 range, and the second rail is installed to shift from a high range through a neutral range into a low range. An elongated hole is formed in a connection portion of the shift link connected to the first and second rails.

The transmission mechanism of the intermediate transmission of the present invention for achieving the above object, the first and second rails installed in parallel in the intermediate transmission mounted to the four-wheel drive of the military vehicle for fixing the fork for the shift; A transmission link connected to the first and second rails at the same time so as to interlock with the first and second rails; A rod connected to one end of the transmission link; And a shift lever connected to one end of the rod to operate the rod.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에는 본 발명에 따른 중간변속기의 변속기구의 구성을 나타낸 사시도가 도시되어 있다.Figure 2 is a perspective view showing the configuration of the transmission mechanism of the intermediate transmission according to the present invention.

도면을 참조하면, 본 발명에 따른 중간변속기의 변속기구는, 군용차량의 4륜구동에 장착되는 중간변속기(20) 내에 평행하게 설치되어 변속을 위한 포크를 고정시켜 주는 제1,2레일(21,22)과, 이 제1,2레일(21,22)에 동시에 연결되어 이들이 연 동되도록 설치된 변속링크(23)와, 이 변속링크(23)의 일 단부에 연결 설치된 로드(24)와, 이 로드(24)의 일 단부에 연결 설치되어 로드(24)를 작동시키는 변속레버(25)를 포함하여 구성된다.Referring to the drawings, the transmission mechanism of the intermediate transmission according to the present invention is installed in parallel in the intermediate transmission 20 mounted on the four-wheel drive of the military vehicle, the first and second rails 21 and 22 for fixing the fork for shifting. ), A transmission link 23 connected to the first and second rails 21 and 22 at the same time so as to be connected to each other, a rod 24 connected to one end of the transmission link 23, and the rod It is configured to include a shift lever 25 connected to one end of the 24 to operate the rod 24.

또한 도 6에 도시된 바와 같이, 상기 변속레버(25)를 N→4x4L위치로 이동하면 로드(24)가 이동하여 제1레일(21)을 힌지로 하여 제2레일(22)이 이동하여 N→4x4L로 변속된다.In addition, as shown in FIG. 6, when the shift lever 25 moves from N to 4x4L, the rod 24 moves to move the second rail 22 to the hinge of the first rail 21. → Shift to 4x4L.

이때 상기 제2레일(22)은 직선운동을, 상기 변속링크(23)는 제1레일(21)의 힌지를 중심으로 회전운동 하여 높이 차(Y)를 보상하여 주기 위하여 변속링크(23)의 연결부에 장공홀을 가공하여 준다.At this time, the second rail 22 is a linear movement, the shift link 23 is rotated about the hinge of the first rail 21 to compensate for the height difference (Y) of the shift link (23) Machine the hole in the connection part.

상술한 바와 같이 본 발명에 따른 중간변속기의 변속기구는 다음과 같은 효과를 갖는다.As described above, the transmission mechanism of the intermediate transmission according to the present invention has the following effects.

군용차량의 4륜구동에 장착되는 중간변속기에서 종래의 2개의 변속레버를 지렛대의 원리를 이용하여 변속레버를 1개로 줄임으로써, 조작되는 링크의 구조가 간소화되고, 이에 따라 정비되는 부품의 수가 감소되며, 조립되는 부품의 수가 감소되고, 부품 수의 감소로 원가절감에 기여할 수 있다.In the intermediate transmission mounted on the four-wheel drive of a military vehicle, by reducing the two shift levers to one using the lever principle, the structure of the operated link is simplified and the number of parts to be maintained is reduced. Therefore, the number of parts to be assembled can be reduced, and the reduction in the number of parts can contribute to cost reduction.

그리고 차량의 운전석 조작레버 갯수의 감소로 운전석의 거주성이 증대되고, 운전의 편리성이 제공될 수 있으며, 레버 오조작에 의한 사고 위험을 줄일 수 있다.In addition, by reducing the number of driver's seat operating levers of the vehicle, the occupancy of the driver's seat can be increased, driving convenience can be provided, and the risk of accidents due to misoperation of the lever can be reduced.

본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 보호 범위는 첨부된 특허청구범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
