At present,most electric vehicles use single motor drive system,the control strategy is simple,but the high-efficiency area is unique.In order to improve the power and economy of the vehicle under diverse working conditions,a reducer with dual motor input was designed,one of the motors is directly connected to the reducer,the connecting or disconnecting of another motor was realized by overrunning clutch.At the same time,high contact ratio gear was adopted to improve the stability of the transmission system.The test results show that dual motor can switch normally,various performance parameters of the reducer satisfied standard requirements,the research method can provide a reference for increasing the driving range of electric vehicle under the premise of satisfying the dynamics performance of the vehicle.
