A clutch and/brake device module (1) is provided with a radiating element (3), and the radiating element (3) is attached to a transmission shell to be used for exhausting heat. The brake module is further provided with a brake disc (5) which is connected to a rotating component which is formed by a shaft (7), and the shaft (7) is shown schematically by a central line; and one face, facing the radiating element (3), of the brake disc is provided with a lining (9). A brake device is a dry type brake device and is not lubricated. The brake device module is further provided with an actuation system (11), that is a cylinder body and a piston in the cylinder body, and the actuation system is shown schematically by an arrow. The actuation system can directly exerts axial pressure to the brake disc (5), and the brake disc is located between the radiating element and the actuation system; and a cooling plate (3) is fixed to the transmission shell (13), and one portion of the cooling plate is shown schematically in a picture.
