Abstract

A construction machine includes a machine frame, left front wheel, left rear wheel, right front wheel, and right rear wheel. Left and right side electric drive motors and reduction gear assemblies are aligned with a drive axis of the left and right front wheels, respectively. Left and right side drive chains connect the left and right side electric drive motors and reduction gear assemblies with the left and right rear wheels, respectively. A left side drive clutch is positioned between the left front wheel and the left side electric drive motor and reduction gear assembly. A right side drive clutch is positioned between the right front wheel and the right side electric drive motor and reduction gear assembly. A controller is configured to selectively engage or disengage the left and right side drive clutches to selectively provide two wheel drive or four wheel drive.
