Abstract
A compact friction plate damper having a primary plate and a secondary plate, which interacts by means of a friction element. A speed-dependent control device is provided for the friction, wherein the friction device has a contact arrangement upon which force is to be exerted essentially radially. The friction control device comprises a spring element, which takes effect with rotational speed-dependent force on the contract arrangement in an essentially radial manner. In addition to this, the friction device interacts by friction with the secondary plate, and is mounted so as to be rotationally movable in relation to the primary plate by at least a small angle. Thus the friction control comprises a rotational speed-dependent coupling element between the primary plate and the friction device.
