Vehicle, especially tractor or vehicle with auxiliary drive, has second control device coupled to gas pedal and operated by gas pedal to control hydraulic pump's transport volume in working mode

摘要

The vehicle has a combustion engine driving a controllable transport volume hydraulic pump(s), a hydraulic motor(s) driven by the pump(s) and driving one or more drive elements, a gas pedal for varying the engine revolution rate in road travel mode and a first control device for controlling the pump's transport volume in working mode. A second control device is operated by the gas pedal to control the pump's transport volume in working mode. The vehicle has a combustion engine (20), at least one hydraulic pump driven by the engine and with controllable transport volumes, at least one hydraulic motor driven by the at least one pump and driving one or more drive elements, a gas pedal for varying the engine revolution rate in road travel mode and a first control device for controlling the pump's transport volume in working mode. A second control device coupled to the gas pedal is operated by the pedal to control the pump's transport volume in working mode
