Design and Optimization of the Suspension System for In-Wheel DrivenElectricVehicles

1， 1， 1， 1， 1， ² （1. ，Wuhan43Oo56;2. ，） 【Abstract】Akey challenge in developing in-whee motor drivenelectric vehicles based onMcPherson suspension platform is thespatialconflictbetween the motorand thesuspension，which leads toaredesignof thesuspensionsystem.In orderto solve theproblem，a C-class vehicle is takenasa prototype，and the McPhersonsuspensionsystem before he prototypeisimprovedbycombining thenew structure withthein-wheel motor while keeping theassmbly interfacebetween thechassis andthelowerbodyunchanged.Using Adams/Carsoftware tobuildamulti-bodydynamicssimulation model，the kinematicscharacteristics of paralel wheel jump，rolland steering of suspension systemareanalyzedandoptimized.The analysisresultsshowthatthekinematics characteristicsof theimproved suspensionsystem can meetthedesign goalof inwheel motor driven electric vehicle as a whole.
