Torsional vibration damper
First Claim
1. A torsional vibration damper comprising:
- a hub;
a flange extending radially out from said hub;
an outer member comprising an annular side plate arranged to one side of said flange and having a central aperture such that the side plate surrounds the hub with a clearance, the side plate being capable of limited angular movement relative to the flange;
circumferentially directed resilient means acting between said flange and side plate to control said angular movement; and
friction damping means located in the clearance between said hub and side plate and comprising a plurality of resilient friction elements in the form of circumferentially directed leaf springs having outer ends supported in the aperture of said side plate and central regions bearing slidably against the outer surface of said hub.

Abstract
A torsional vibration damper for the driven plate of a friction clutch comprises a hub, a flange extending radially out from the hub and an outer member comprising an annular side plate arranged to one side of the flange and having a central aperture such that the side plate surrounds the hub with a clearance. The side plate is capable of limited angular movement relative to the flange with circumferentially directed resilient means acting between the flange and the side plate to control the angular movement. A friction damper is provided between the hub and the side plate and comprises a resilient friction element supported in the central aperture of the side plate and bearing against the outer surface of the hub.
