Abstract
A torque-delivering vehicle drive system having a friction clutch actuated by a pressurized medium, a hydrodynamic working circuit including a pump wheel and a turbine wheel, operatively connected to the friction clutch and a device including an operating lever for adjusting pressure and/or rate of flow of the pressurized medium to the friction clutch including a regulating device for maintaining the torque delivered by the vehicle drive system at a constant value corresponding to a given position of the operating lever, and means for supplying to the regulating device a measured quantity that is a function of a difference in working fluid pressure producible by the pump wheel of the hydrodynamic working circuit.
