Abstract
A friction clutch can typically have a rotary power input member which can be rotationally engaged by means of a torsional damping device such as springs located between the input and output members. The output member can include a hub, non-rotationally connected to a hub disc, and the input member can include at least one disc-shaped member disposed adjacent the hub disc, which disc-shaped member can have friction linings for engaging a rotating part of an engine. The torsional damping device can include a base friction apparatus and a load friction apparatus for which friction rings are used, which rings have an internal axial stress and generate the frictional force as a result of their material properties and their axial friction mounting.
