Abstract

The invention relates to the technical field of electric automobiles, and discloses a wheel assembly and an electric automobile chassis. The wheel assembly comprises a connecting base, side mounting bases arranged on the two sides of the connecting base and a wheel device located between the two side mounting bases, the wheel device is provided with a rotating shaft, and the two ends of the rotating shaft are rotationally connected with damping connecting blocks; and rotary arms are hinged to the two sides of each damping connecting block, the upper ends of the rotary arms are movably connected to the side mounting bases, and first damping springs are arranged on the side mounting bases. The wheel assembly has the following advantages and effects that the wheel assemblies are installed on the electric automobile chassis, each wheel assembly can independently steer, steering is flexible, the degree of freedom is high, the chassis is low and stable in form, balance is good, and the wheel assembly can be used as a sweeper, a logistics vehicle, a wharf vehicle, a take-out vehicle and the like.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a wheel assembly and an electric vehicle chassis. Background technique [0002] Electric vehicles refer to vehicle-mounted power supplies as power and motors to drive wheels. They have the advantages of no pollution and low noise, and their impact on the environment is smaller than that of traditional vehicles. The Chinese Utility Model Patent CN213501724U discloses a four-wheel independent drive and steering electric vehicle chassis as the authorized notification number, which adopts an up and down swing mechanism to realize the instant adjustment of the height of the vehicle disc on uneven ground. The Chinese utility model patent with authorized notification number CN205615576U discloses a car chassis assembly with four-wheel wheel motor drive and four-wheel independent steering, including vehicle frame, steering motor, spring shock absorber assembly, and its spring s...
