Abstract:
A dampening disk assembly, comprising:a first rotary plate having a first axial side and a second axial side;a second rotary plate disposed at said second axial side of said first rotary plate, said second rotary plate being fixedly coupled to said first rotary plate with a space formed therebetween;an intermediate member disposed in said space between said first rotary plate and said second rotary plate, said intermediate member having a first axial side being axially supported by said first rotary plate and a second axial side facing said second rotary plate, said intermediate member including a supporting portion located at an inner circumferential portion of said second axial side of said intermediate plate;an elastic member coupling said first rotary plate and said second rotary plate to said intermediate member elastically in a rotary direction;an output hub disposed adjacent to said inner circumferential portion of said intermediate member between said first rotary plate and said second rotary plate, said output hub having a cylinder-shaped portion and a flange portion extending in a radial direction-from said cylinder-shaped portion, said flange portion having a first axial side being axially supported by said first rotary plate and a second axial side being disposed adjacent to a first axial surface of said supporting portion of said intermediate member with a space formed therebetween;a friction generating mechanism disposed between said flange portion and said supporting portion to generate friction as said output hub rotates relatively against said intermediate member, said friction generating mechanism comprisinga first friction member connected with said output hub in a relatively non-rotatable but axially movable manner and abutting said first axial surface of said supporting portion, anda first urging member disposed on said second axial side of said intermediate member in a compressed manner axially between said flange portion and said first friction member to apply a first resilient force to said first friction member and said flange portion; anda second urging member disposed on said second axial side of said intermediate member in a compressed manner axially between said second rotary plate and a portion of said intermediate member other than said supporting portion to apply a second resilient force larger than said first resilient force of said first urging member to said intermediate member and said second rotary plate.
