The embodiment of the invention provides a wheel set, a bogie and a rail vehicle. The wheel set comprises: an axle; a wheel relative to the axle in an axial direction, wherein at least two groups of locking grooves which are sequentially distributed in the axial direction are formed in each wheel; a positioning disc which is arranged on the axle and rotates synchronously with the axle; a clamp which comprises two clamp claws which are symmetrically arranged, wherein each clamp claw is provided with a first end, a second end and a rotating portion between the first end and the second end, and the rotating portions are connected with the positioning disc through a pin shaft; a relieving disc which is arranged on the positioning disc and rotates synchronously with the positioning disc, wherein the relieving disc moves in the first direction to apply force to the first ends of the clamp claws, so that the clamp claws rotate to the second ends to be disengaged from the locking grooves, andthe relieving disc moves in the second direction to apply force to the first ends of the clamp claws, so that the clamp claws rotate to the second ends to be inserted into the locking grooves. According to the wheel set, the bogie and the rail vehicle provided by the embodiment of the invention, the requirement on a ground rail transfer device can be reduced.
本申请实施例提供了一种轮对、转向架及轨道车辆,其中,轮对包括:车轴;车轮,可沿轴向方向相对于车轴移动;车轮上设置有沿轴向方向依次排布的至少两组锁定槽;定位盘,设置在车轴上与车轴同步转动;夹钳,包括对称设置的两个钳爪;钳爪具有第一端、第二端、以及位于第一端和第二端之间的转动部,转动部通过销轴与定位盘相连;缓解盘,设置在定位盘上与定位盘同步转动;缓解盘沿第一方向移动,以对钳爪的第一端施力,以使钳爪转动至第二端从锁定槽脱出;缓解盘沿第二方向移动,以对钳爪的第一端施力,以使钳爪转动至第二端插入所述锁定槽。本申请实施例提供的轮对、转向架及轨道车辆能够降低对地面变轨装置的要求。
