Abstract
A clutch disc assembly (1) is provided a lubrication member (11) to suppress the wear of parts which contact any of the 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) is confined within the window (3c), the raised portions (4a) and (5a) of the plates (4) and (5) and the separated flange (3) in the circumferential direction. A lubricant-impregnated member (11) is provided in the plates (4) and (5), and is contactable with the large spring coil (7).
Claims16
A damper disc assembly comprising:
- a first rotary plate having a first receiving portion;
- a second rotary plate disposed rotatably relative to said first rotary plate and having a second receiving portion corresponding to said first receiving portion;
- an elastic member disposed within said first receiving portion and said second receiving portion for coupling the first rotary plate to said second rotary plate in the circumferential direction;
- and
- a lubricant-impregnated member provided adjacent to at least one of said first rotary plate and said second rotary plate and contactable with said elastic member;
- wherein said first rotary plate comprises two plates, and said lubricant-impregnated member is clamped between said two plates.
A damper disc assembly comprising:
- a hub formed with a radially outwardly extending flange, said flange formed with a first cutaway;
- a first rotary plate formed with a second cutaway and a first receiving portion;
- a first spring member disposed within said first and second cutaways elastically coupling said hub and said first rotary plate;
- a second rotary plate disposed concentrically with said first rotary plate and configured to be relatively rotatable to said first rotary plate and having a second receiving portion corresponding to said first receiving portion;
- a second spring member disposed within said first receiving portion and said second receiving portion for elastically coupling the first rotary plate to said second rotary plate in the circumferential direction;
- and
- a lubricant-impregnated member provided adjacent to said first rotary plate, contactable with said elastic member;
- wherein said first rotary plate comprises two plates, and said lubricant-impregnated member is clamped between said two plates.
