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.

    本发明实施例提供了一种基于鼓刹制动的紧凑型可解耦电动车驱动装置,电机(1)的输出轴(1‑1)连接行星减速器(2)的太阳轮A(2‑1);行星减速器(2)的传力盘(2‑8)连接鼓刹制动器(3)的制动鼓(3‑1);鼓刹制动器(3)的制动架(3‑3)连接电机(1)的法兰杯(1‑2);电机(1)经法兰杯(1‑2)连接悬架或驱动桥;电机(1)的动力经输出轴(1‑1)传递给行星减速器(2)的太阳轮A(2‑1),经过两级行星减速传动,经传力盘(2‑8)输出至轮毂或驱动桥,同时传力盘(2‑8)带动鼓刹制动器(3)的制动鼓(3‑1)转动,通过鼓刹制动器(3)的手动操控拉线(3‑8)带动鼓刹制动器(3)的制动蹄(3‑2)抵紧制动鼓(3‑1)摩擦制动。
