The invention relates to the technical field of railway vehicle wheel sets, and provides a disc brake type wheel set which comprises a transmission shaft, a pair of shaft sleeves, a shell, a movable disc, a fixed disc and wheels. 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. A first actuator is arranged in the first braking area, and a second actuator is arranged in the second braking area so as to generate axial thrust on the movable disc and the fixed disc. The invention further provides a bogie and a railway vehicle. The defects that in the prior art, a traditional rail vehicle braking device causes extra loads to the axle, high energy consumption and large inter-spring mass are brought to the rail vehicle, and the braking torque is insufficient in the wheel steering process are overcome, the lightweight design of the axle is achieved, the braking torque is sufficient when the vehicle steers, and the running safety of the rail vehicle is guaranteed.

    本发明涉及轨道车辆轮对技术领域,提供一种盘式制动型轮对,包括传动轴、一对轴套、壳体、动盘、定盘以及车轮;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;第一制动区中设置有第一作动器,第二制动区中设置有第二作动器,以对动盘和定盘产生轴向推力。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对车轴造成额外负荷、对轨道车辆带来较高的能耗和较大的簧间质量、车轮转向过程中制动扭矩不足的缺陷,实现了车轴的轻量化设计,且车辆转向时制动扭矩充足,保障了轨道车辆的行驶安全。
