ABSTRACT:
A clutch disc assembly (1) is provided with lubrication members (11a, 11b) to reduce the wear of the parts which contact the large coil springs (7) disposed within the clutch disc assembly (1). Plates (4) and (5) and a separated flange (3) are configured to rotate relative to each other. Raised portions (4a) and (5a) of the plates (4) and (5) correspond to a window (3c). Each of the large coil springs (7) extends in a circumferential direction with respect to the clutch disc assembly (1). Each large coil spring is confined within a corresponding the window (3c) of the separated flange (3) and further between the raised portions (4a) and (5a) of the plates (4) and (5). Lubricant-impregnated members (11a, 11b) are provided on a portion of respective sides of the separated flange (3), and are contactable with the large spring coil (7). In one alternate embodiment, a portion of plates (105) and (106) is provided with a plurality of minute apertures (140). The plates (105) and (106) are then provided with a surface hardened layer (130) to reduce wear due to friction.
