Friction clutch plate with damping springs

摘要

A clutch plate (100) including a plate assembly (111) having an annular periphery to which an assembly of friction material (114,115) is applied to face in opposite directions. A hub (120) is provided for connection to an output shaft and a hub flange (132) is driveable by the plate assembly to rotate. The hub (120) is driveable to rotate by the hub flange (132). The hub (120) and the hub flange (132) are angularly displaceable relative to each other within a predetermined range and are coupled together by a tension spring (125) which extends radially relative to the axis of rotation of the hub and which applies a biasing load against relative angular displacement between the hub (120) and the hub flange (132). A further embodiment is disclosed where the plate assembly (111) and the hub flange (132) are angularly displaceable relative to each other within a predetermined range and being coupled together by at least two curved drive springs (150 151) having a constant radius of curvature and being mounted concentric about the hub (120).

1. A clutch plate including:
a plate assembly having an annular periphery to which an assembly of friction material is applied to face in each of opposite directions, a hub for connection to an output shaft, a hub flange drivable by the plate assembly to rotate, the hub being drivable to rotate by the hub flange, the hub and the hub flange being angularly displaceable relative to each other within a predetermined range and being coupled together by a coil spring which extends radially relative to the axis of rotation of the hub and which applies a biasing load against relative angular displacement between the hub and the hub flange, opposite ends of the coil spring being anchored to the hub and the hub flange by rivets that are upstanding from the hub and the hub flange.
