| 摘要 |
The invention relates to a clutch transmission for motor vehicles, comprising a dry single clutch (27) or a dry dual clutch (1), which transmits the torque from the motor to the transmission or optionally to one of two partial transmissions, and a cooling system having a fan wheel system for the active air cooling of the single clutch (27) or the dual clutch (1), wherein the particular clutch has a central disk (3) and a pressure plate (4, 5) on at least one side, which pressure plate optionally can be coupled to the central disk (3), and wherein the central disk (3) and/or at least one of the pressure plates (4, 5) has passages (12) for the cooling air flow (17), which extend radially or have a radial component. In order to further improve and optimize the cooling system, which is already known for a dual clutch, and to be able to use said cooling system also for single clutches, the passages (12) according to the invention are formed by ribs (13) and/or grooves (16) provided in the central disk (3) and/or the pressure plates (4, 5) and that the direction of the cooling air flow and/or the cooling air amount together with the cooling mass can be set by the form and arrangement of the ribs (13) and/or grooves (16). |
