Research of Theoretical Analysis and Structural Design of Active Wheel
Drive system of wheel motor is getting more and more attention by automobile manufacturers and researchers. In this paper, a novel drive system of electric vehicle with two degrees of freedom is given, with active wheel driven by two motors, which can work freely under three modes of single motor low speed, double motor high speed and regenerative braking. Furthermore, theoretical analysis based on mechanical dynamics is implemented for all these modes. Detailedly, on an experiment and design platform of a mini electric vehicle, comprehensively considering and balancing structure dimension of testing prototype and expected performance requirements, design of overall structure of the active wheel is accomplished.
