摘要
A four-wheel drive assist for electric machines includes an electric drive system for driving wheels at a non-steering end and a selectively operable hydraulic system for driving wheels at a steering end. A controller controls the operation of the drive system according to operator selection and/or by detecting slipping of the electric drive system. Preferably, at least one hydraulically driven operating arm, including boom functions, lift platform, etc., is driven by the same hydraulic pump that drives the steering end hydraulic system. The machine thus is capable of effecting four-wheel drive when necessary, while operating as efficiently as a conventional two-wheel drive full electric machine when the four-wheel drive system is not engaged.
