A clutch assembly is disclosed having a driving plate arranged in communication with a thermal transfer medium for use in cooling the driving plate. The disclosed thermal transfer medium can include at least one conductive brush that is mounted with the driving plate and arranged between the driving plate and a separate cooled part of the clutch assembly for cooling the driving plate. The brush may also be resiliently biased for contact with the cooled part of the clutch assembly so that it brushes against it.

Clutches

A dual clutch transmission has a driving plate defining concentric engagement surfaces, concentric friction plates, concentric pressure plates, and first and second clutch springs for operation of the pressure plates in clamping the friction plates against their respective engagement surface on the driving plate. The driving plate has a top hat type configuration, whereby the engagement surfaces are axially off set from one another. Cooling passages may be provided in the driving plate. The dct is preferably nested, wherein the outer pressure plate is in axial alignment with the radially inner portion of the driving plate, the inner pressure plate is in axial alignment with the radially outer portion of the driving plate, and the friction plates are arranged in axial alignment with one another.
