PURPOSE:To enable to absorb the torque vibration or the resonance of the damper disc upon starting, stopping and high-speed running by a method wherein an oil- type shock absorber is accommodated within the damper disc to vary the hysteressis torque thereof in accordance with a twisting angle. CONSTITUTION:A flange 2 for a spline hub 1 is covered with cases 3, 4 from both of the left and right sides thereof and a cushioning plate 7 is fixed to the case 3 by means of a rivet 5. Large or small diametral compression coil springs 17, 18, extending in the circumferential direction are fitted into window holes 20 of the flange 2 and the parts of the springs projecting left and right from the window holes 20 are covered by the semicylindrical recesses 21, 22 of the cases 3, 4 to form spring accommodating chambers 40. Oil is filled in these chambers 40 as well as clearances between the cases 3, 4 and the flange 2 to constitute the oil-type shock absorber. Other compression coil springs 19 are interposed between the springs 17, 18 on the disc. |
