The invention discloses a main pin zero bias wire-controlled independent driven and steering automobile running mechanism and an electric vehicle for solving the problems of complex mechanism and low vehicle stability. The mechanism consists of a steering component, a suspension component and a wheel component. The steering component consists of a main pin assembly and a steering vertical shaft assembly. The main pin assembly comprises a steering motor (1), a speed reducer (2), a speed reducer output flange (3), a main pin sleeve (5), a main pin (6) and a coding disc (7); and the steering vertical shaft assembly comprises a main steering arm (8), a steering vertical shaft (12), an upper distance plate (19) and a lower distance plate (24). The suspension component comprises an upper springseat (10), a shock absorber (11), a spring (13) and a lower spring seat (14). The wheel component comprises a hub motor (16), a wheel (18) and a wheel bracket (22). The electric vehicle consists of aframe (28), the main pin zero bias wire-controlled independent driven and steering automobile running mechanism (27) and an electric control system.
