Research on the double trailing arm suspension of EV direct wheel drive system

According to the difference between electric vehicles and traditional vehicles, the transmission system of electric vehicles needs corresponding changes to meet requirements of electric vehicles. This paper studied on the integration of double trailing arm suspension and electric engine. The structure of the system was analyzed in detail. And the UG models were established. The transmission strategy was studied based on detailed calculation. Finally Adams software was employed to analyze the kinematic characteristics of the spring of the suspension system.
