Abstract

본 발명은 변속 레버의 조작으로 작동되는 일련의 기계적 작동구조를 유압과 공기압에 의해서 작동될 수 있도록 하는 트랜스미션 기어 시프트 구조에 대한 것으로, 특히 변속 레버의 조작에 의해 오일 파이프로부터 오일이 유출입되도록 하는 실린더 A와; 상기 오일 파이프를 통해 일측으로 유입되는 오일에 의해 타측으로부터 유입되는 공기를 압축시키도록 하는 실린더B와; 일측면이 상기 실린더B의 타측면과 연통되어 에어 탱크로부터 공기가 상기 실린더B측으로 유입되도록 한 실린더C와; 상기 실린더B로부터 공기가 유도되도록 하여 피스톤과 시프트 암을 이동시켜 시프트 포크의 조오와 체결되도록 하는 실린더D로 이루어져 변속 레버의 조작으로 실린더간의 유압에 의해 공기의 공급을 단속시키므로서 쉬프트 암이 작동되도록 하여 기어 쉬프트 포크의 조오(Jaw)를 작동케 하므로서 유압과 공압에 의한 유연한 변속이 되도록 하는 동시에 차체 중량을 대폭 감소시킬 수 있도록 하고, 공기의 반력감으로 보다 확실한 변속이 이루어지도록 하는 트랜스미션 기어 시프트 구조에 대한 것이다.The present invention relates to a transmission gear shift structure that enables a series of mechanical actuation structures operated by the operation of a shift lever to be operated by hydraulic and pneumatic pressure, and in particular, a cylinder which allows oil to flow in and out of an oil pipe by operating the shift lever. With A; A cylinder B for compressing air introduced from the other side by oil introduced into one side through the oil pipe; A cylinder C having one side communicating with the other side of the cylinder B such that air is introduced into the cylinder B from an air tank; It is composed of a cylinder D to induce air from the cylinder B to move the piston and the shift arm to be engaged with the jaws of the shift fork to operate the shift lever to control the supply of air by hydraulic pressure between the cylinders so that the shift arm can be operated. Transmission gear shift structure enables jaw of the gear shift fork to be smoothly shifted by hydraulic pressure and pneumatic pressure, and greatly reduces the weight of the body, and makes transmission more reliable by feeling of reaction force of air. It is about.
