摘要： PROBLEM TO BE SOLVED: To improve a vibration damping effect for a crank shaft by adding damping function of a friction force on a two-mass type fly wheel. SOLUTION: A first fly wheel 5 is manufactured by effecting press processing of a plate and a cylinder part 16, a ring groove 5a, and a friction surface 5b are formed on the central side. A disc 21 to be brought into dynamic friction is fitted in the cylinder part 16 togetherwith friction rings 22 and 23 and brought into pressure contact with the friction surface 5b through the force of a coned disc spring 25 to form a friction coupling part 11. One-sided contact of the friction ring 22 with the friction surface 5b is prevented by the ring groove 5a. The outer end of the disc 21 to be brought into dynamic friction is engaged with a spring device 12 and torque is transmitted to the driven side through a spring device 12, a driven disc 33, and a second fly wheel 14. This constitution damps a part of vibration rotation of a crank shaft 4 by the friction force of a friction coupling part 11.

摘要： PURPOSE:To enhance smoothing performance of the rotation by simplifying the structure of a viscosity damper provided on a two mass-type flywheel. CONSTITUTION:Spring receivers 301 to 304 are made to project to an inner plate 8 and a spring holding plate 28 on the driving side from the lateral direction, so as to hold both ends of first springs 32. Pots 391 to 394 are provided on a driving part 13 of a viscosity damper, and end walls 37 of two pots are brought in contact with both ends of one first spring 32, and the front ends of the pots 391 to 394 are inclined. A driven part 14 receives torque through second springs 34, and plungers 42 provided on the driven part 14 are retreated into the pots 391 to 394, so as to pressurize viscous fluid inside the pots, thereby the driven part is subjected to the damping action by the viscosity. When vibration is small, small damping force acts and when vibration is large, large damping force acts due to the inclination on the front end.
