Abstract
A clutch disk assembly includes axially opposed clutch and retaining plates 3 and 4. A flange having a plurality of circumferentially long recesses is arranged between clutch and retaining plates. A plate coupling portion 30 extends through a recess at the flange and connects the clutch and retaining plates 3 and 4 together.
Claims15
A damper disk assembly comprising:
- a pair of first circular plates axially opposed to each other;
- a second circular plate disposed between said paired first circular plates, said second circular plate being configured for limited relative rotation with respect to said pair of said first circular plates, and said second circular plate being formed on an outer circumferential portion with a plurality of circumferentially extending recesses;
- an elastic member being adapted to be compressed in response to relative rotation between said paired first circular plates and said second circular plate;
- a first of said paired first circular plates being formed with a plurality of plate coupling portions formed homogeneously with said first of said paired first circular plates, each of said plate coupling portions extending in a generally axial direction from an outer circumferential edge of said first of said paired first circular plates, each of said plate coupling portions extending through a corresponding one of said recesses formed in said second circular plate, each of said plate coupling portions further formed with a radially inwardly extending portion, said radially inwardly extending portion being connected to a second of said paired first circular plates;
- and
- wherein said plate coupling portions are configured to engage circumferential ends of said recesses in response to relative rotation between said second circular plate and said paired first circular plates thus limiting relative rotation therebetween.

A damper disk assembly comprising:
- a pair of first rotary circular plates axially opposed to each other;
- a second rotary circular plate arranged between said paired first rotary circular plates;
- a third rotary circular plate being adjacent to said second rotary circular plate and having a circumferentially long recess;
- a first elastic member adapted to be circumferentially compressed by relative rotation between said first and third rotary circular plates;
- a second elastic member adapted to be circumferentially compressed by relative rotation between said second and third rotary circular plates;
- and
- a plate coupling portion extending through said recess in said third rotary circular plate, said plate coupling portion being formed homogeneously with one of said paired first rotary circular plates, said plate coupling portion including an axially extending portion extending through said recess, a circumferential length of said axially extending portion being shorter than a corresponding circumferential length of said recess, said plate coupling portion further including a radially inwardly extending portion which connects to the other of said paired first rotary circular plates coupling said paired first rotary circular plates together, wherein
- when the relative torsion angle between said first and third rotary circular plates is small, said first and second elastic members act in series, and when said relative torsion angle is large, said first rotary circular plate is in contact with and compresses said second elastic member, and wherein said plate coupling portions are configured to engage circumferential ends of said recesses in response to relative rotation between said second circular plate and said paired first circular plates thus limiting relative rotation therebetween.

A damper disk assembly comprising:
- a pair of first annular plates axially opposed to each other;
- a second annular plate arranged between said first annular plates, said second annular plate configured for limited relative rotary displacement with respect to said first annular plates, said second annular plate being formed with at least one circumferentially extending recess on an outer circumferential portion thereof;
- an elastic member disposed between said first annular plates, said elastic member being compressible in response to relative rotary displacement between said first annular plates and said second annular plate;
- and
- at least one plate coupling portion extending through said recess connecting said first annular plates together and providing a stop limit to relative rotary displacement between said first annular plates and said second annular plate, said plate coupling portion being formed homogeneously with one of said first circular plates, said plate coupling portion including an axially extending portion extending through said recess, a circumferential length of said axially extending portion being shorter than a corresponding circumferential length of said recess, said plate coupling further including a claw which extends radially inwardly and connects to the other of said first rotary circular plates, and wherein said plate coupling portion is configured to engage circumferential ends of said recesses in response to relative rotation between said second circular plate and said paired first circular plates thus limiting relative rotation therebetween.
