Abstract

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.

Description

technical field [0001] The invention relates to a vehicle running mechanism applied to a vehicle, more specifically, the invention relates to a vehicle running mechanism with integrated driving, steering and damping functions at the wheel. Simultaneously, the invention also relates to an electric vehicle using the vehicle running mechanism with the kingpin zero-bias wire-controlled independent drive and steering. Background technique [0002] An electric vehicle driven by an in-wheel motor adopts the suspension and steering system of a conventional vehicle. Such electric vehicles have poor maneuverability, and the driver must have considerable skills and complex operations to move the vehicle in a relatively small space. At the same time, the traditional design of the suspension and steering system is to sacrifice the dynamics of the vehicle in exchange for the stability of the vehicle. sex. With the rapid development of control-by-wire technology and mechatronics, its app...
