Abstract: The present invention relates to a freewheel arrangement (4) having a freewheel (2), which comprises a first running ring (44), a second running ring (46), at least one clamping element (26; 28) that is between the first and the second running ring (44, 46) and is movable between a coupling position and a release position, and an actuating element (42) for adjusting the at least one clamping element (26; 28), wherein the actuating element (42) can be arranged on the first running ring (44) and is movable relative to the first running ring (44). A friction device (52) for generating a frictional force acting on the actuating element (42) is provided, the frictional force counteracting a drive force acting on the first running ring (44) so as to move the actuating element (42) relative to the first running ring (44). The present invention furthermore relates to a drivetrain (82) having such a freewheel arrangement (4).

Abstract: A composite clutch (110) is adapted to transmit an operational range of torques (60) from a driving member (118) to a driven member (122). The composite clutch (110) incorporates both of a friction clutch assembly (124) and a dog clutch assembly (126), each assembly adapted to address one of two segments (62, 68) of the operational range of torques (60). The clutch (110) further includes a spring-loaded detent system (180) configured to control transition (66) between the two segments (62, 68) of operational ranges of torques (60). The friction clutch assembly (124) includes first friction clutch elements (128) coupled to the driving member (118) and second friction clutch elements (132) coupled to the driven member (122) for providing torque control within the lower operational range of torques (64). The dog clutch assembly (126) includes a first dog clutch element (136) coupled to the driving member (118) and a second dog clutch element (138) coupled to the driven member (122), in which the first and second dog clutch elements (136, 138) are configured to mechanically lock together during the higher operational range of torques (70).

Abstract: A friction material includes a friction-generating layer and a base layer. The base layer includes base fibers and presents a bonding surface. The friction-generating layer includes friction-adjusting particles deposited on the base layer and presents a friction-generating surface facing opposite the bonding surface of the base layer. A curable resin is present in the friction-generating layer and the base layer. The friction material also includes a composition including a plurality of triglycerides. The composition is present in at least one of the friction-generating layer and the base layer. The plurality of triglycerides comprises polyunsaturated fatty acid in a content of from 60 to 90% by weight based on a total weight of the plurality of triglycerides included in the composition.

Abstract: A dual gain friction clutch is adapted to transmit an operational range of torques from a drive member to a driven member. The dual gain friction clutch incorporates a first friction clutch pack and a second friction clutch pack, the pack being axially aligned and adapted to address one of two segments of the operational range of torques. The clutch further includes a spring-loaded skate detent unit configured to control transition between the two segments of operational ranges of torques. Each friction clutch pack may include identical respective friction discs coupled to the drive member and respective pressure plates coupled to the driven member for selectively providing torque control within either of the lower and higher segments of the operational ranges of torques. The first clutch pack is configured to operate alone and independently of the second clutch pack during the lower segment of operational range of torques while and both friction clutch packs are configured to operate as a single combined friction clutch unit during the higher segment of operational range of torques.
