Integrated cooling system for a dry dual clutch of a dual clutch transmission

摘要

A dual clutch transmission for motor vehicles, has two transmission sections, a dry dual clutch (1), which transmits the torque from the engine selectively to one of the two transmission sections, and a cooling system having a fan impeller system for active air cooling of the dual clutch (1). To optimize the individual functional parts of the cooling system and to reduce the clutch masses, it is proposed that the central disk (3) and/or at least one contact pressure plate (4, 5) is/are designed as a fan impeller of the fan impeller system (21). The central disk (3) and/or at least one of the contact pressure plates (4, 5) has/have passages which extend radially or have a radial component.

1. A dual clutch transmission system for motor vehicles, comprising:
a transmission having two transmission sections; and a dry dual clutch transmitting a torque from an engine of the vehicle selectively to one of the two transmission sections, wherein the dual clutch is comprised of a central disk and a pair of pressure plates; wherein the dual clutch includes a cooling system comprised of an embedded fan impeller system for active air cooling of the dual clutch; wherein the fan impeller system is comprised of a plurality of internal passages formed in at least one of the central disk and the pressure plates.
