  • Publication number: 20200056665
    Abstract: 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.

  • Patent number: 8789675
    Abstract: A clutch device having at least one torque transfer device that can be engaged and disengaged in the axial direction and is frictionally engaged in the engaged state, and at least one wear adjustment device, which has at least one rotatable adjusting ring, at least one rotatably supported spindle drive with a drive pinion, which acts on the adjusting ring, and at least one drive assembly which may be made to engage with the drive pinion and which is pre-tensioned in the axial direction, to turn the spindle drive in the case of wear, the pre-tensioning force of the drive assembly being stepped.
