Double clutch device for a drive train of a motor vehicle with fully hydraulic actuation

摘要

The invention relates to a double clutch device for a drive train of a motor vehicle with fully hydraulic actuation, comprising a first radially external partial clutch (2) and a second second partial clutch (3) radially inside the first partial clutch (2), pressure chambers (4, 5) of the first and the second partial clutch (2, 3) and / or centrifugal oil chambers (6, 7) of the first and the second partial clutch (2, 3) are arranged radially within the second partial clutch (3) and a pressure chamber (5) of the second partial clutch (3 ) and a centrifugal oil chamber (6) of the first partial coupling (2) are delimited by a common partition (16). In a double coupling device in which the installation space is made very compact, the partition is designed as a seal carrier (16) on which a sealing element (22) with two sealing lips (17, 20) is arranged, the first sealing lip (17) the pressure chamber (5) of the second partial coupling (3) and the second sealing ippe (20) seals the centrifugal oil chamber (6) of the first partial clutch (2).
