The invention provides a hydraulic braking power device. A containing cavity is formed in a shell assembly, a first channel and a second channel which are oppositely arranged penetrate through the containing cavity, and an isolation part and the containing cavity form a first oil cavity and a second oil cavity which are independent of each other. The first hydraulic channel is communicated with the first oil cavity, and the second hydraulic channel is communicated with the second oil cavity. The first power assembly comprises a first piston and a second piston, the first piston is relatively sealed and movably connected into the first oil cavity, and the second piston is relatively sealed and movably connected into the second oil cavity. The second power assembly is located in the containing cavity, penetrates through the second channel and is connected with the shell assembly in a relative moving mode, and the first piston and the second piston are connected with the second power assembly in an acting mode. The transmission assembly penetrates through the first channel and is connected with the second power assembly, and the transmission assembly is connected with the shell assembly in a relative movement mode. The invention further provides a hydraulic braking system and a rail train.

    本发明提供一种液压制动动力装置,壳体组件内形成有容纳腔,相对设置的第一通道和第二通道贯穿至容纳腔,隔离部与容纳腔形成相互独立的第一油腔和第二油腔。第一液压通道与第一油腔相连通,第二液压通道与第二油腔相连通。第一动力组件包括第一活塞和第二活塞,第一活塞相对密封且移动连接于第一油腔内,第二活塞相对密封且移动连接于第二油腔内。第二动力组件位于容纳腔内,第二动力组件穿过第二通道,第二动力组件与壳体组件相对移动连接,第一活塞和第二活塞分别与第二动力组件相作用连接。传动组件穿过第一通道,传动组件与第二动力组件相连接,传动组件与壳体组件相对移动连接。本发明还提供一种液压制动系统及轨道列车。
