The present invention relates to a freewheel () having a first race (), a second race (), a clamping gap () formed between the first and second race (), at least one clamping element () in the clamping gap () and a pre-tensioning device () for pre-tensioning the clamping element () in a clamping position inside the clamping gap (), wherein the pre-tensioning device () has a spring element () supported indirectly or directly on the first race (). The pre-tensioning device () further has a spring support frame () that can be moved in relation to the first race (), in which spring support frame the spring element () is arranged.

Freewheel having a pre-tensioning device for clamping elements

The present invention relates to a frictionally-acting device () comprising a disk pack () made from a first disk set () and a second disk set (), wherein disks of the disk sets () are arranged alternating one after another and can be frictionally engaged with one another. An intermediate disk (), provided with a friction lining on one side, is arranged between a support disk () and a disk () of the first disk set () adjacent to the support disk (), the intermediate disk () is in rotary driving connection with a second disk carrier (), and the friction lining of the intermediate disk () faces the support disk ().

Frictionally-acting device and use of an intermediate disk and/or an actuation disk in such a frictionally-acting device

A torsional-vibration damper includes at least one primary element and a secondary element that can be coupled to each other by a spring device, are limited in movement in relation to each other about a rotational axis, and can be brought into frictional contact with each other by a friction device. The friction device has at least two friction-surface-carrying elements rubbing against each other to which a contact-pressure force, generated by a force-generating device, can be applied to produce a frictional engagement between the two elements. The force-generating device has a mechanical actuating mechanism for generating an actuating force and a hydraulic actuating mechanism for generating a counterforce, wherein the contact-pressure force is a vector sum of the actuating force and the counterforce.
