Abstract
A clutch module for a dual clutch transmission (DCT) is designed to improve circumferential fluid distribution to reduce or eliminate an unpleasant noise during engagement. In some embodiments, the reaction plate is restrained in a position offset 1-3 degrees from perpendicular to the housing axis. Consequently, 0.2-0.7 mm of clearance remains on one radial side of the clutch when all clearance has been removed on the other radial side of the clutch. Relative rotation between the hub and the housing pushes fluid from the tight side toward the loose side. In an alternative embodiment, the piston is designed to orient the pressure plate non-perpendicular to the housing axis.
