Friction lining for dry running friction clutch of clutch disk in vehicle, has material or material mixture provided with negative thermal expansion coefficient in longitudinal direction of fibers of material or material mixture

摘要

The lining (16) has a material or material mixture i.e. fiber material, provided with a negative thermal expansion coefficient in a longitudinal direction of fibers e.g. aramid fibers and carbon fibers, of the mixture. The thermal expansion coefficient provides negative thermal expansion perpendicular to a friction surface of the lining. A fiber portion amounts to 50% of the mixture. The lining comprises a local exposed region and an anti-friction surface. A hub disk (8) is attached at external teeth (6), and a covering carrier (12) is attached at the disk by an attachment element (10).
