The invention discloses a power assembly for electric wheel type engineering machinery, and belongs to the field of engineering machinery, particularly wheel type loaders. The power assembly comprises a power assembly box body, a working device power unit and a walking power unit, the power assembly box body comprises a gearbox, a transfer case and a power output box; the transfer case is located in the upper portion of the gearbox; and the power output box is located in the lower portion of the gearbox. Working device driving, walking driving, the transfer case, the gearbox, front and back output and the like are integrated, and independent driving of a hydraulic pump, a steering pump and a brake pump of a working device can be met; and the walking driving motor can also independently drive the loader to walk, the structure is compact, maintenance is convenient, cost is low, the wheel type engineering machinery such as the loader can obtain the best working performance, and the working efficiency of the whole machine can be remarkably improved. The motor is adopted for driving, forward and backward switching can be achieved through reverse rotation of the motor, and the gearbox does not need a reversing mechanism.

    本发明公开了一种电动轮式工程机械用动力总成,属于工程机械尤其是轮式装载机领域。包括动力总成箱体、工作装置动力单元、行走动力单元;上述动力总成箱体包括变速箱、分动箱以及动力输出箱;所述分动箱位于变速箱的上部;动力输出箱位于变速箱的下部;本发明将工作装置驱动、行走驱动、分动箱、变速箱及前后输出等集成为一体,可满足工作装置液压泵、转向泵及制动泵的独立驱动;行走驱动电机也可独立驱动装载机行走,结构紧凑、维修保养方便、成本较低,使装载机等轮式工程机械获得最佳的工作性能,并可显著提高整机的工作效率。采用电机驱动、利用电机的反向转动即可实现前进和后退切换,变速箱不需要换向机构。
