The invention provides a drive synthesis device and an electric vehicle. The drive synthesis device comprises a transmission assembly at least comprising a power source and a reduction gear assembly and an axle package assembly composed of a main speed reducer and a differential mechanism, and the transmission assembly and the axle package assembly are fixed to a frame of a vehicle together. According to the drive synthesis device, the transmission assembly and the axle package assembly are fixed to the frame of the vehicle together, the unsprung mass is reduced, and the NVH performance is improved.
本发明提供了驱动合成装置以及电动车辆。该驱动合成装置包括:至少包括动力源和减速齿轮组件的变速器总成以及由主减速器和差速器组成的桥包总成,所述变速器总成和所述桥包总成一起固定在车辆的车架上。本发明实施例的驱动合成装置通过将变速器总成和桥包总成一起固定在车辆的车架上,减小了簧下质量,提升了NVH性能。
