The invention provides a multi-motor driving device and a vehicle, and relates to the technical field of vehicles. The multi-motor driving device comprises at least two power sources and a speed reduction gear assembly; each power source comprises a driving motor and a motor shaft connected with the driving motor; the speed reduction gear assembly comprises a second gear assembly and at least twofirst transmission gears connected with the motor shafts in a one-to-one correspondence mode, each first transmission gear is meshed with a second transmission gear, and a gear pair formed by the at least two first transmission gears and the second transmission gear has at least two speed ratios. By the adoption of the arrangement of the multiple sets of small-torque and high-rotating-speed driving motors, the medium-high-speed power performance can be guaranteed while the large-torque requirement of the low-speed working condition is met, and the manufacturing and purchasing cost is reduced.The plurality of small motors adopt different speed ratios, so that the stable operation of each motor can be ensured, and the generation of resonance is avoided.

    本发明提供了一种多电机驱动装置及车辆,涉及车辆技术领域。本发明的多电机驱动装置包括:至少两个动力源,各动力源包括驱动电机和与所述驱动电机相连的电机轴;减速齿轮组件,包括一个第二齿轮组件和与电机轴一一对应相连的至少两个第一传动齿轮,每一第一传动齿轮均与第二传动齿轮啮合,且至少两个第一传动齿轮与第二传动齿轮形成的齿轮副具有至少两种速比。本发明采用多组小扭矩、高转速驱动电机的布置可在满足低速工况的大扭矩需求的同时保证中高速的动力性能,并降低制造和采购成本。本发明的多个小电机采用不同的速比,可以保证各电机平稳运转,避免共振的产生。
