The invention provides an integrated driving system for reducing unsprung mass, a power assembly and a vehicle. The driving system comprises a frame, a sliding rail, a sliding column, a driving unit, a wheel assembly and a retainer. The sliding rail is connected with the frame; the sliding column is connected with the frame; the driving unit is in sliding fit with the sliding rail; the wheel assembly is in sliding fit with the sliding columns. The driving unit is connected with the wheel assembly and used for providing power for the action of the wheel assembly; the retainer is in running fit with the output end of the driving unit and the input end of the wheel assembly and used for keeping the relative distance between the driving unit and the wheel assembly. A motor and a suspension system are integrated, the mass of the motor and the suspension system is completely converted into sprung mass, the unsprung mass brought by the motor and the transmission system is effectively reduced, the chassis space is saved, the motor with high power can be used, the modularization level of a chassis walking system is effectively improved, and the cost is reduced. The driving system has great advantages when being applied to buses and logistics vehicles requiring low chassis height.

    本发明提供一种用于减小簧下质量的一体化驱动系统、动力总成及车辆,所述驱动系统包括:车架、滑轨、滑柱、驱动单元、车轮组件和保持架;滑轨与车架连接;滑柱与车架连接;驱动单元与滑轨滑动配合;车轮组件与滑柱滑动配合;驱动单元与车轮组件连接,用于为车轮组件的动作提供动力;保持架分别与驱动单元的输出端和车轮组件的输入端转动配合,用于保持驱动单元与车轮组件之间的相对距离。本发明通过将电机与悬架系统集成并将其质量完全转化为簧上质量,有效减小电机及传动系统带来的非簧载质量,并节约底盘空间,且可以使用较大功率电机,有效提高底盘行走系统的模块化水平,应用于要求底盘高度低的公交车以及物流车上有较大优势。
