The invention relates to the technical field of railway vehicle braking devices, in particular to a disc type braking device which comprises a transmission shaft and a pair of shaft sleeves arranged on the transmission shaft in a sleeving mode. The movable disc, the fixed disc and the actuator are located in the shell, and the movable disc and the fixed disc are arranged in the shell at intervals in the axial direction of the shell. 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 suitable for acting in the axial direction of the shell. The actuators are evenly distributed in the shell in the circumferential direction of the shell and generate axial thrust on the movable discs and the fixed discs in the axial direction of the shell so that the adjacent movable discs and fixed discs can be close to each other and attached to each other and generate circumferential friction when the transmission shaft rotates. The invention further provides a bogie and a railway vehicle. The problems that in the prior art, a traditional rail vehicle braking device is large in mass, and wheel rail impact is likely to happen in the braking process are solved, the lightweight design of the axle is achieved, and the braking efficiency is improved.

    本发明涉及轨道车辆制动装置技术领域,具体提供一种盘式制动装置,包括传动轴、套设在传动轴的一对轴套;还包括壳体、位于壳体中的动盘、定盘以及作动器,动盘和定盘沿壳体的轴向相互间隔排列在壳体中;动盘活动连接在传动轴,定盘活动连接在壳体,且动盘与定盘均适于沿壳体的轴向动作;作动器沿壳体的周向均布在壳体中,且作动器沿壳体的轴向对动盘和定盘产生轴向推力,以使相邻的动盘和定盘在传动轴转动时相互靠近贴合并产生周向摩擦。本发明还提供一种转向架和一种轨道车辆。本发明解决了现有技术中传统的轨道车辆制动装置质量较大、制动中容易发生轮轨冲击的问题,实现了车轴的轻量化设计,提高了制动效率。
