The embodiment of the invention provides a compact type decoupling electric vehicle driving device based on drum brake braking. An output shaft (1-1) of a motor (1) is connected with a sun gear A (2-1) of a planetary reducer (2); a force transmission disc (2-8) of the planetary reducer (2) is connected with a brake drum (3-1) of the drum brake (3); a brake frame (3-3) of the drum brake (3) is connected with a flange cup (1-2) of the motor (1); the motor (1) is connected with a suspension or a drive axle through a flange cup (1-2); power of the motor (1) is transmitted to a sun gear A (2-1) of the planetary reducer (2) through an output shaft (1-1) and is output to a hub or a drive axle through a force transmission disc (2-8) after two-stage planetary reduction transmission, meanwhile, the force transmission disc (2-8) drives a brake drum (3-1) of the drum brake (3) to rotate, and the drum brake (3) is driven to rotate. A brake shoe (3-2) of the drum brake (3) is driven by a manual control stay wire (3-8) of the drum brake (3) to abut against the brake drum (3-1) for friction braking.
