The invention provides a braking power device. The braking power device comprises a shell assembly, a first power assembly, a second power assembly and a transmission assembly. The transmission assembly comprises a first transmission part, a first limiting part, a second transmission part and a third transmission part, wherein the first transmission part is in relative movement connection with thefirst channel; one end of the second transmission part is in threaded transmission connection with the first transmission part, the second transmission part is connected with the first elastic part,the second transmission part is relatively rotationally connected with the second power assembly through the first elastic part, and a first clamping part is arranged at the other end of the second transmission part; and the third transmission part is connected with the second power assembly, the third transmission part is provided with a second clamping part, and the second clamping part can be connected with the first clamping part in a clamped mode. According to the braking power device, the second transmission part and the third transmission part are prevented from being disengaged in thebraking and releasing process, and the reliability of the braking power device is further guaranteed. The invention further provides a hydraulic braking system and a rail train.

    本发明提供一种制动动力装置,包括壳体组件、第一动力组件、第二动力组件和传动组件。传动组件包括:第一传动件、第一限位件、第二传动件和第三传动件,第一传动件与第一通道相对移动连接;第二传动件一端与第一传动件相互螺纹传动连接,第二传动件与第一弹性件相连接,第二传动件通过第一弹性件与第二动力组件相对转动连接,第二传动件另一端设置有第一卡合部;第三传动件,第三传动件与第二动力组件相连接,第三传动件设置有第二卡合部,第二卡合部能够与第一卡合部相互卡合连接。本发明提供的制动动力装置,防止制动及缓解过程中第二传动件与第三传动件脱开,进一步保证制动动力装置的可靠性。本发明还提供一种液压制动系统及轨道列车。
