The invention relates to the technical field of railway vehicle braking devices, and provides a compound full-disc braking device which comprises a transmission shaft, a pair of shaft sleeves, a shell, a movable disc, a fixed disc and an actuator. The space formed by the shell and the shaft sleeve is a first braking area and a second braking area which are independent of each other, the movable disc is movably connected to the transmission shaft, the fixed disc is movably connected to the shell, and the movable disc and the fixed disc are arranged in the shell at intervals and suitable for acting in the axial direction of the shell. The actuators are evenly distributed in the shell and generate axial thrust on the movable disc and the fixed disc, the actuators comprise the first actuator and the second actuator, the first actuator is located in the first braking area, and the second actuator is located in the second braking area. The invention further provides a bogie and a railway vehicle. The defects that in the prior art, a traditional rail vehicle braking device is large in mass, extra loads are caused to an axle, the braking efficiency is reduced when faults occur, and potential safety hazards are caused are overcome, the reliability and universality of the braking device are improved, and the driving safety of the rail vehicle is guaranteed.

    本发明涉及轨道车辆制动装置技术领域,提供一种复式全盘制动装置,包括传动轴、一对轴套、壳体、动盘、定盘以及作动器;壳体与轴套形成的空间为相互独立的第一制动区和第二制动区,动盘活动连接在传动轴,定盘活动连接在壳体,动盘和定盘相互间隔排列在壳体且均适于沿壳体的轴向动作;作动器均布在壳体中并对动盘和定盘产生轴向推力,作动器包括第一作动器和第二作动器,第一作动器位于第一制动区,第二作动器位于第二制动区。本发明还提供一种转向架和轨道车辆。解决了现有技术中传统的轨道车辆制动装置质量较大、对车轴造成额外负荷、发生故障时降低制动效率并导致安全隐患的缺陷,提高了制动装置的可靠性和通用性,保障了轨道车辆的行驶安全。
