Torsion bar spring double wishbone independent suspension for wheel side driving electric vehicle

Abstract

The invention relates to a torsion bar spring double wishbone independent suspension for a wheel side driving electric vehicle. The suspension includes a front suspension and a rear suspension that are disposed on a vehicle frame; the front suspension and the rear suspension have a same structure, and each include a left suspension, a right suspension, and a stabilizer bar connected between the left suspension and the right suspension; the left suspension and the right suspension have the same structure, and each include a torsion bar spring mechanism, a knuckle, an upper swing arm, a vibration damper, and a lower swing arm; the torsion bar spring mechanism comprises a torsion bar spring, a torsion bar spring bracket, an adjustment screw rod, an adjustment nut, an adjustment arm, a mounting bracket and a perforated pin; and the front suspension and the rear suspension together form the torsion bar spring double wishbone independent suspension, force and force torsion acting between vehicle wheels and the vehicle frame are transmitted, the impact force transmitted to the vehicle frame or a vehicle body by an uneven road surface is buffered, and vibration caused by the force is reduced to ensure that an automobile can be driven smoothly. The torsion bar spring is adopted, and so, an occupied space is smaller, the suspension is advantageous for overall layout design, energy storage density is high, and a structure is simple.

Description

technical field [0001] The invention relates to a torsion-bar spring double-wishbone independent suspension, in particular to a torsion-bar spring double-wishbone independent suspension suitable for a vehicle driven by a wheel-side motor. Background technique [0002] With the world energy crisis and the increasingly serious air pollution, people are paying more and more attention to the development of new energy vehicles. In my country, in order to promote the development of energy vehicles, the country has issued a series of policies and regulations, and the development of new energy vehicles is unstoppable. . An electric bus refers to a bus powered by the on-board power supply and equipped with a suitable on-board battery or cable power supply equipment to provide electric energy for driving. In the process of developing the mechanical structure of electric buses, how to develop a suspension system that can be well matched with the electric drive system is an important ta...
