The invention provides a combined type power mechanism for engineering machinery. The combined type power mechanism comprises an engine used for driving a walking assembly and a pumping assembly of the engineering machine; the engine is connected to an input port of the power transmission unit, and the pumping assembly and the walking assembly are independently connected to a first output port and a second output port of the power transmission unit correspondingly; and the electric motor is configured to be connected to the first output port of the power transmission unit in series with the pumping assembly so as to replace the engine to drive the pumping assembly, and when the engine is used for driving the pumping assembly, the electric motor is dragged by the engine through the power transmission unit to be in an idle state. By means of the combined type power mechanism, an existing indexing box can be used, and the complexity of the mechanism and the construction cost of the mechanism cannot be increased too much. The invention further provides an engineering machine provided with the combined type power mechanism.
本发明提供了一种用于工程机械的复合式动力机构。该复合式动力机构包括:发动机,其用于驱动该工程机械的行走组件和泵送组件;动力传输单元,发动机连接于动力传输单元的输入端口,泵送组件和行走组件相对于彼此独立地分别连接于动力传输单元的第一输出端口和第二输出端口;以及电动马达,其被配置成与泵送组件串联地连接于动力传输单元的第一输出端口,以代替发动机驱动泵送组件,其中,在使用发动机驱动泵送组件时,电动马达被发动机经动力传输单元拖动而处于空转状态。利用本发明的复合式动力机构,能够使用现有的分度箱,并且不会过多地增加机构复杂度及机构构建成本。本发明还提供了一种设置有前述复合式动力机构的工程机械。
