Hydrodynamic converter for vehicle, has switchable guide wheel has switchable control wheel actuated by switch element in form of lamella coupling or conical clamp coupling or combination

摘要

The device has a pump wheel, a turbine wheel, a control wheel and the oil required for the transfer of torque. The control wheel is switchable and can be actuated by a switch element in the form of a lamella coupling or a conical clamp coupling or a combination of a lamella coupling and a conical clamp coupling. Independent claims are also included for the following: the use of a hydrodynamic converter for improving vehicle start-off characteristics and for reducing tendency to creep and gearbox take-up torque for a vehicle with an automatic gearbox.
