Hydrostatic drive for lorry - has pump driven by combustion engine and electronic control system to limit power and to regulate fuel consumption

摘要

The hydrostatic drive has a hydrostatic pump (5), driven by the vehicle's combustion engine (1), and a hydro-motor arrangement (15) coupled to the vehicle's output drive (11) that lies between the combustion engine and one pair of the vehicles wheels. An electronic or electrical power limited produces a control signal to reduce the power when a selectable max. power is exceeded. An electronic or electrical control unit monitors and controls measured or wanted parameter in order to optimise the control of fuel consumption, to reduce emissions, to reduce noise, to optimise torque or power, to limit slip, and to prevent excessive angular speeds (eg when going downhill). USE/ADVANTAGE - For industrial and commercial vehicles. Cheap. Adequate power at slowest speed.
