Suspension design for single-passenger electric vehicles

摘要

This paper presents a novel suspension design for single-passenger Electric Vehicles, with four in-wheel-motor drive and all-wheel independent steering. Since this design keeps the advantage of each wheel's independent steering and power driven, a suspension system employs motorcycle steering dampers tempers under supporting by head tube. This paper presents a 3D metal printing (additive manufacture) design of a key part of the suspension, an integrated head tube to improve the steering angle for each wheel e.g. turning to 90-degree to allow a parallel parking for a small size EV. Software simulation proved the yield strength of the shaft and bearing hub. Safety analysis is presented based on mass re-distribution experiment.
