Hydraulic control device for triggering a double clutch, especially in an automatic double-clutch gearbox or in a hybrid drive system has actuators, a proportional valve and distributing valves

摘要

First (1) and second (3) hydraulically triggered actuators work for first and second clutches in a double clutch respectively. A proportional valve (PV) (5) has an inlet (E5) with a main hydraulic pressure (PHaupt) and an outlet (A51), on which a first hydraulic operating pressure (P1) adjusted by the PV can be removed. First (7) and second (9) distributing valves have inlets and outlets. An independent claim is also included for a method for hydraulic triggering of pressure- controlled actuators, especially coupling actuators.
