A mechanical motor-driven friction brake device for a rail vehicle consists of a torque motor, an electromagnetic brake (5), a screw nut transmission mechanism, and a brake friction pair (6), the torque motor and a screw (4) being coaxially mounted, the screw (4) being in non-self-locking threaded connection with a nut (3), and one end of the nut (3) being connected to the brake friction pair (6); the device drives, by means of the torque motor, the screw (4) to rotate so as to drive the nut (3) to perform linear motion and outputs a pressure or a pulling force to the brake friction pair (6), so as to brake or release the rail vehicle; in addition, this device can lock the screw by means of the electromagnetic brake (5), realizing the function of parking brake.
