A parking brake mechanism and gear mechanism linkage device of a vehicle comprises a parking brake, a parking hydraulic cylinder, a first manual reversing valve, a forward gear clutch, a backward gearclutch, a hydraulic pump, an oil tank, a second manual reversing valve, a first hydraulic control reversing valve and a second hydraulic control reversing valve. An execution port of the first manualreversing valve is communicated with a first oil inlet of the first hydraulic control reversing valve and a first control port of the second hydraulic control reversing valve respectively. An execution port of the second manual reversing valve is communicated with a second oil inlet of the first hydraulic control reversing valve, a control port of the first hydraulic control reversing valve and asecond control port of the second hydraulic control reversing valve respectively. An execution port of the first hydraulic control reversing valve is communicated with the parking hydraulic cylinder.An execution port of the second hydraulic control reversing valve is communicated with the forward gear clutch, and the execution port of the second hydraulic control reversing valve is communicatedwith the backward gear clutch. A forward gear can be automatically engaged when parking brake of a cab at the front end is released, and a backward gear can be automatically engaged when parking brakeof a cab at the rear end is released.

    一种车辆的停车制动机构和挡位机构联动装置,包括停车制动器、停车液压缸、第一手动换向阀、前进挡离合器、后退挡离合器、液压泵、油箱、第二手动换向阀、第一液控换向阀和第二液控换向阀;第一手动换向阀的执行口分别与第一液控换向阀的第一进油口和第二液控换向阀的第一控制口连通;第二手动换向阀的执行口分别与第一液控换向阀的第二进油口、第一液控换向阀的控制口和第二液控换向阀的第二控制口连通;第一液控换向阀的执行口与停车液压缸连通;第二液控换向阀的执行口与前进挡离合器连通,第二液控换向阀的执行口与后退挡离合器连通。本发明能在前端部的驾驶室解除停车制动时自动挂前进挡,在后端部的驾驶室解除停车制动时自动挂后退挡。
