摘要： A drive system for a utility vehicle, such as a fork-lift truck, comprises a hydrostatic transmission whose pump is driven by an electric shunt-wound motor having a field winding so energized, under the control of a potentiometer responsive to the fluid pressure in the transmission, that the field current varies inversely with transmitted torque over at least a portion of the speed range of the vehicle. The automatic potentiometer control exerted by the fluid pressure may be overridden by a manually operable lever. The same potentiometer can be used to vary the motor speed in response to the output pressure of another pump which is driven by the electric motor and coupled with the fork-lifting mechanism of the vehicle.
