Patent number: 10968961Abstract: A friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft of a motor vehicle transmission includes a lamina, an axially movable contact plate, and a plurality of friction disks. The lamina has a first friction surface facing in a first axial direction, and a second friction surface facing in a second axial direction, opposite the first axial direction. The contact plate has a plurality of holders arranged to hold the lamina. Each of the holders forms a positive connection with the lamina in the circumferential direction, and each of the first friction surface and the second friction surface is frictionally connectible to a friction disk to transmit torque. A first friction disk is arranged to be positioned between a counter plate and the lamina, and a second friction disk is positioned between the lamina and the contact plate.Type: GrantFiled: April 5, 2018Date of Patent: April 6, 2021Assignee: Schaeffler Technologies AG & Co. KGInventors: Vladimir Merk, Christophe Acker, Sebastien Morel, Alexander Obitz, Marc Helfer
