The invention discloses a multi-axle chassis driving system and a crane, and belongs to the technical field of engineering machinery. The device comprises a mechanical driving device, a mechanical driving system and an electric driving system, the mechanical drive system comprises a front drive axle assembly and a rear drive axle assembly, and the mechanical drive device, the front drive axle assembly and the rear drive axle assembly form at least two-axle drive through a transfer case. The electric driving system is used for providing driving force for the whole vehicle when the getting-off power is insufficient or the transmission capacity is insufficient; the electric driving device replaces hydraulic driving, efficiency is high, the structure is simple, arrangement is convenient, complex hydraulic pipelines and hydraulic elements such as pumps and motors are omitted, and the oil leakage risk is reduced.

    本发明公开一种多桥底盘驱动系统及起重机,属于工程机械技术领域。其包括机械驱动装置、机械驱动系统及电驱动系统;所述机械驱动系统包括前驱动桥总成和后驱动桥总成,所述机械驱动装置通过分动箱与前驱动桥总成和后驱动桥总成至少构成两桥驱动;所述电驱动系统用于在下车动力不足或者传递能力不足时为整车提供驱动力;本发明通过电驱动装置替代液压驱动,效率高,结构简单,布置方便,取消了复杂的液压管路及泵、马达等液压元件,减少漏油风险。
