Hydraulic switch device and method to control a wet double-clutch

摘要

The hydraulic circuit for the control of a wet running double-clutch, for an automatic gearbox, has a hydraulic actuator (1,2) for each of the two clutch sections. A cooling unit (20) supplies a coolant for the double-clutch. A hydro pump (6) feeds the system pressure line (5) for the actuators and a hydraulic buffer store (11) for system pressure, with an electromotor drive (7).
