The Floating Cup principle strongly increases the efficiency of hydraulic pumps, motors and transformers. Recent tests have proven an efficiency of up to 98%. For automobiles and other vehicles, this opens the opportunity for the ‘Hydrid’: a full hydraulic hybrid transmission between engine and wheels. The Hydrid has in-wheel hydraulic motors, hydraulic transformers for variable traction control and a common pressure rail including accumulators for power management and energy recuperation. The Hydrid offers the same advantages as hybrid electric drive trains, but without the cost penalty.
