Friction clutch driven plate

摘要

A friction clutch driven plate comprises first and second disk-like carrier plates rivetted together and having first and second flat spokes respectively on their peripheries. A single integral annulus of friction material is held in place by the first spokes in a first recess in a first face of the annulus and by the second spokes in second recesses in an opposite second face of the annulus. The carrier plates are also connected together by stop rivets passing through arcute slots in a third disc between the carrier plates. In known fashion torsional vibration damping springs are disposed in windows in the carrier plates and the third disc. The third disc has a central hole lined by splines to engage similar splines on a shaft. First and second bearing bushes are disposed in the central openings of the carrier plates. These bushes have internal diameters substantially equal to that of the root circle of the splines on the third disc so that the bushes will sit on the tips of the splines on said shaft whereby the bushes and third disc are supported substantially co-axially.
