Abstract

A friction clutch for a transmission of a motor vehicle generally will have a clutch disc, and the clutch disc will be provided with friction linings for engaging the friction clutch with a rotating engine flywheel. The friction rings can be provided, on both surfaces thereof with trough-shaped depressions, to reduce the weight of the clutch disc. The trough-shaped depressions can essentially be rectangular or square, with rounded corners and with connecting surfaces which are steeply diagonal, or curved with a large radius of curvature.
