The invention provides an auxiliary coupling device for a transition coupler, a rail vehicle transition coupler and a rail vehicle. The auxiliary coupling device for the transition coupler comprises arotary hook assembly, a support, a rotating shaft and a locking mechanism, wherein the rotary hook assembly comprises a cylinder and an auxiliary hook; the support comprises a first through hole anda second through hole; the rotating shaft comprises a shaft body and a positioning groove; the locking mechanism is arranged in the second through hole of the support and keeps abutting against the rotating shaft; the locking mechanism is provided with a base part fixedly connected to the second through hole and a positioning part capable of performing reciprocating motion in the radial directionrelative to the base part; at a locking position, the positioning part abuts against the positioning groove; at a non-locking position, the positioning part abuts against the shaft body; when the locking mechanism is switched from the locking position to the non-locking position, a force not less than a preset value is applied to the rotary hook assembly, and the rotating shaft in linkage with therotary hook assembly enables the positioning part of the locking mechanism to be pushed out of the positioning groove to abut against the shaft body. The auxiliary coupling device is reliable in locking and convenient to switch.

    本申请提供一种过渡车钩用辅助连挂装置、轨道车辆过渡车钩及轨道车辆。该过渡车钩用辅助连挂装置包括:旋转挂钩组件,其包括柱体以及辅助挂钩;支座,其包括第一贯通孔以及第二贯通孔;转轴,其包括轴体以及定位槽;以及锁紧机构,其设置在支座的第二贯通孔内并保持抵压转轴;其中,锁紧机构具有固定连接于第二贯通孔的基部以及能够相对于基部沿径向发生往复运动的定位部;其中,在锁止位置时,定位部抵压定位槽;在非锁止位置时,定位部抵压轴体;在从锁止位置切换至非锁止位置时,旋转挂钩组件被施加不小于预设值的力,与其联动的转轴使锁紧机构的定位部从定位槽被推出至抵压轴体。本申请的辅助连挂装置锁紧可靠且切换方便。
