Abstract

A friction plate (55) for use in a friction damper (50) with a shaped radially outer (55a) or radially inner first periphery which cooperates with a similarly shaped first periphery of a further component (54) of the damper to transfer torque between the friction plate (55) and the further component, the first periphery of the friction plate comprising a plurality of drive surfaces (55B), at least one of which is substantially tangential or chordal to the friction plate (55). The friction plate (55) may additionally have a second periphery with second drive surfaces tangential or chordal to the friction plate or it may additionally have drive formations formed as axially projecting lugs on an axially orientated surface of the friction plate. The friction plate (55) may be manufactured by sintering techniques or may have a sintered coating applied to its friction surface. A friction plate manufactured by sintering techniques may have sintered unitary ramps, and/or lip, and/or lugs provided thereon. Also shown is a twin mass flywheel (10) including a friction damper with at least 2 friction surfaces (54, 55) which rotate relative to each other and are biased by a load into engagement with each other during at least part of the relative rotation and the bias load is reacted by an inner (19A) or outer (19B) race of bearing (19) the said inner (19A) or outer (19B) race being axially fixed between a shoulder and a plate of the twin mass flywheel (10).
