| 摘要 |
The invention concerns a drive train comprising a double clutch transmitting the engine torque to two primary clutch shafts (4, 6) of a gearbox, each clutch comprising a disc (24, 40, 118, 136) connected in rotation to one of the primary clutch shafts, which can be enclosed between two plates one of which (26, 42, 116, 134) is axially mobile under the effect of a control, one of said controls including a piston (52, 152) guided by a cylindrical surface integrated in an axial housing of a primary clutch shaft (6). The invention is characterized in that the cylindrical guide surface is located very proximate the shaft housing, said surface being directly made in the shaft housing or in a body (170) inserted in the housing the end of which is connected to the gearbox housing (174) via an attachment transferred outside the housing. |
