Hydraulic circuit for controlling dual clutch gearbox, especially for motor vehicle, has central distributing valve device between switching cylinders and pressure valves

摘要

The Hydraulic circuit has a proportional flow valve (5,5') connected before each coupling cylinder (2,3) and a proportional pressure valve device (4,4',4'',4''') associated with each switching cylinder (7,8,9,10). A central distributing device (21) is arranged between the switching cylinder and pressure valves. An Independent claim is included for a method of hydraulically controlling a dual clutch gearbox.
