The invention relates to the technical field of braking systems, and provides a full disc type braking device and method, a wheel drive system and a railway vehicle. The full-disc brake device comprises a shell, a disc hub, a static disc, a movable disc and a brake cylinder. The shell is suitable for being fixedly connected with a shell of the motor; the disc hub is rotationally arranged in the shell, and the disc hub is fixedly connected with the non-output end of a rotating shaft of the motor; the static disc is axially connected to the shell in a sliding mode, and axial rotation limiting is formed by the static disc and the shell. The movable disc is arranged on the disc hub and is suitable for synchronously rotating with the disc hub; the brake cylinder is used for driving the static disc and the movable disc to be in contact fit for braking. According to the invention, a full-disc braking mode is adopted, the motor is mounted at the non-output end of the rotating shaft of the motor, and the motor is not directly connected with the axle, so that no additional braking bending moment is added to the axle, lightweight design of the axle is facilitated, the axle does not need to be provided with a braking shaft disc or a wheel disc, unsprung mass is greatly reduced, and dynamic performance is provided.

    本发明涉及制动系统技术领域,提供一种全盘式制动装置、方法以及轮驱系统、轨道车辆。全盘式制动装置包括壳体、盘毂、静盘、动盘和制动缸;壳体适于与电机的外壳固定连接;盘毂转动设置在所述壳体内,所述盘毂与所述电机的转轴的非输出端固定连接;静盘轴向滑动连接于壳体,并与所述壳体形成轴向旋转限位;动盘设置于所述盘毂,适于与所述盘毂同步旋转;所述制动缸用于驱动所述静盘和所述动盘接触配合制动。本发明采用全盘制动型式,安装在电机的转轴的非输出端,与车轴没有直接连接,因此对车轴没有附加的制动弯矩,有利于车轴轻量化设计,车轴无需设置制动轴盘或轮盘,簧下质量大大减轻,有助于提供动力学性能。
