The invention provides a crawler drive unit and a construction machine. A crawler drive unit (1) according to one embodiment of the present invention is provided with: a speed reduction mechanism (4) that is provided to a traveling unit (102) that causes a vehicle body (101) to travel, and that transmits driving force to a crawler provided to the traveling unit (102); a transmission mechanism (3) that transmits driving force to the speed reduction mechanism (4); and an electric motor (2) that applies rotational force to the transmission mechanism (3). A motor shaft (7) of the electric motor (2) is positioned above a rotation axis (Jn) of an input shaft (16) of the speed reduction mechanism (4).
本发明提供履带驱动单元和施工机械。本发明的一形态的履带驱动单元(1)具备:减速机构(4),其设置于使车身主体(101)行驶的行驶部(102),向设置到行驶部(102)的履带传递驱动力;传递机构(3),其向减速机构(4)传递驱动力;以及电动马达(2),其对传递机构(3)赋予旋转力。电动马达(2)的马达轴(7)位于比减速机构(4)的输入轴(16)的旋转轴线(Jn)靠上方的位置。
