Abstract
The one or the other group of transmission speeds of a motor vehicle transmission is adapted to be alternately connected with a double clutch having a clutch housing driven from the engine crankshaft by way of a central shaft and a hollow shaft concentric thereto. For that purpose, two clutch disks are provided which are hydraulically pressed alternately against a center plate of the clutch housing. Two mutually concentric annular pistons serve for the actuation of the clutch disks which are arranged in a two-partite hydraulic plate threadably fastened at the clutch housing.
