The invention relates to gearbox for pivot steering of a fixed-shaft wheeled machine. The gearbox comprises a speed change mechanism, a central transmission structure, a speed reduction mechanism, a first half shaft gear, a second half shaft gear and a control mechanism which are fixedly arranged in a gearbox body and are sequentially connected, wherein the first half shaft gear and the second half shaft gear are arranged at the two sides of the gearbox, body; the central transmission mechanism comprises a central gear, a first clutch gear and a second clutch gear, and a power transmission path is changed by controlling the engagement and disengagement between the second clutch gear and the central gear; and the control mechanism comprises a control shaft, a diaphragm clutch, a first control gear and a second control gear, the diaphragm clutch is arranged on the control shaft, the diaphragm clutch controls the second control gear to keep synchronous rotation with the first control gearor not, and then the rotating direction of the second half shaft gear is changed; By means of the gearbox structure, static friction between a caterpillar band at one side and the ground during mechanical steering can be avoided, so that abrasion of the caterpillar band is reduced, and the service life of the caterpillar band is prolonged.

    本发明涉及一种定轴轮式机械原地转向用变速箱,包括固定设于变速箱内的依次连接的变速机构、中央传动结构、减速机构、设于变速箱两侧的第一半轴齿轮和第二半轴齿轮、控制机构,中央传动机构包括中央齿轮、第一离合齿轮和第二离合齿轮,通过控制第二离合齿轮与中央齿轮之间的嵌合与分离改变动力的传输的路径;控制机构包括控制轴、设于控制轴上的膜片离合器、第一控制齿轮、第二控制齿轮,通过膜片离合器控制第二控制齿轮是否与第一控制齿轮保持同步转动,进而改变第二半轴齿轮的转动方向;本发明通过该变速箱结构能够避免机械转向时一侧履带与地面的静摩擦,从而减少履带的磨损,延长其使用寿命。
