Research on a Hub Hydraulic Motor Driving System of Electric Vehicle

Abstract:

This paper applies hydraulic transmissions advantages of small volume, light weight, quick response, stable transmission, great transmission torque and agile spatial arrangement etc. to hub electromotor drive electric vehicle, substitutes hub hydraulic motors for hub electromotors, propose a hub hydraulic motor driving system of electric vehicle. The constitution and working principle of system is then described in detail. The hub hydraulic motor driving system proposed in this paper will help electric vehicle to realize continuously variable transmission, leave out reducer and differential mechanism, reduce the unsprung mass of electric vehicle, make the spatial arrangement of electromotors and batteries more flexible, and achieve the integration control of electric vehicles driving, braking and steering.
