The invention relates to a main clutch hub (5), especially for a motor vehicle clutch, preferably a double clutch (1) of an automatic or automated double-clutch transmission for transmitting the power flux between an engine shaft (2) and at least one friction clutch (K1, K2), a hub member (6) being provided. The invention further relates to a double clutch (1), particularly for a motor vehicle transmission, preferably an automatic or automated double-clutch transmission, comprising a clutch housing (15), a first and second friction clutch (K1, K2) which can be connected to an engine shaft (2) at one end and to a respective transmission input shaft (3, 4) at the other end, and a main clutch hub (5) that is disposed between the engine shaft (2) and the friction clutches (K1, K2) within the power flux and is fitted with a hub member (6). In order to reduce the effort for producing the main clutch hub (5), the main clutch hub (5) is designed as a single piece, and the hub member (6) has at least one coolant duct (9) which extends from at least one inlet (7) to at least one outlet (8) and is used for supplying coolant to the clutch (1). |
