Hydraulic arrangement for controlling double clutch transmission of drive train of motor vehicle, has valve with functional position for attaching energy source to another valve, so that supply pressure is adjustable to switching pressure

摘要

The arrangement (1) has a valve (11) e.g. 2/4-way proportional control valve, arranged upstream to a switching device (7), and a hydraulic energy source (27) for supplying supply pressure (29) to the arrangement. Another valve (31) is arranged upstream to a clutch device (5) and the former valve. The latter valve exhibits a functional position (35) for wirelessly switching the clutch device and the former valve. The latter valve has another functional position (45) for attaching the energy source to the former valve, so that the supply pressure is adjustable to a switching pressure (51).
