The utility model discloses a gear selecting shaft of a gearbox, the gearbox and a vehicle. Wherein the gearbox comprises a valve seat, a shifting fork and a gear selecting and shifting block, the gear selecting shaft is movably arranged on the valve seat, the gear selecting and shifting block is connected with the shifting fork to drive the shifting fork to move, the gear selecting and shifting block can rotate relative to the gear selecting shaft, the gear selecting shaft comprises a gear selecting shaft body, and the gear selecting shaft body is connected with the shifting fork. A ball capable of rolling is arranged at one end of the gear selecting shaft body and used for abutting against the gear selecting and shifting block. According to the gear selecting shaft of the gearbox, the contact friction force between the gear selecting shaft and the gear selecting and shifting block can be reduced, so that the gear selecting and shifting block rotates more smoothly. 本实用新型公开了一种变速箱的选档轴、变速箱及车辆。其中，所述变速箱包括阀座、拨叉和选换
