Torsion Characteristics on Drive Shaft of Independent Wheel Drive for Articulated Vehicle

The drive shaft of the bi-modal tram has been designed and built into independent wheel drive; all driving wheels are driven by electric motor-gearbox sets independently, in order to make low floor to provide the old and the handicapped with easy access, and to remove differential gears to reduce turning radius. This paper was aimed to evaluate torques on drive shafts while the bi-modal tram was running on slope way in the test track, and at maximum speed in public roadway. On the basis of the torques measured on the drive shafts, torsion characteristics of the independent wheel drive were discussed in this paper.
