The invention discloses a brake device and a rail transit vehicle, and relates to the technical field of rail transit, the brake device comprises a static disc and a movable disc which form a whole disc friction pair, the movable disc is arranged on a brake shaft, at least one of the static disc and the movable disc is provided with a water cooling cavity, and the water cooling cavity is used for storing a water cooling medium; when the movable disc and the static disc are in friction braking, the movable disc transmits braking torque to the braking shaft, and the water cooling medium in the water cooling cavity and the full-disc friction pair achieve heat dissipation through heat exchange. According to the brake device for the rail transit vehicle, the water cooling cavity and the water cooling medium are arranged, the heat dissipation efficiency and reliability of the brake device for the rail transit vehicle in a severe environment are effectively improved in a water cooling mode, and the problems that a traditional air cooling brake device is low in heat dissipation efficiency and prone to being damaged under the severe weather conditions such as sand and dust and ice and snow are solved.
本申请公开了一种制动装置及轨道交通车辆,涉及轨道交通技术领域,所述制动装置包括组成全盘摩擦副的静盘和动盘,所述动盘设于制动轴,所述静盘和所述动盘中的至少一者设有水冷腔,所述水冷腔用于存储水冷介质;当所述动盘与所述静盘摩擦制动时,所述动盘向所述制动轴传递制动扭矩,所述水冷腔中的水冷介质与所述全盘摩擦副通过热交换实现散热。上述用于轨道交通车辆的制动装置,通过设置水冷腔和水冷介质,以水冷方式有效提高了轨道交通车辆制动装置在恶劣环境下的散热效率和可靠性,解决了传统风冷制动装置在沙尘、冰雪等恶劣天气条件下散热效率低和容易受损的问题。
