Abstract
A dampening disk assembly,is provided in a clutch assembly,to make it possible to easily change the level of hysteresis torque when small torsion vibrations are generated. Thus, the level of hysteresis torque can easily be changed to accommodate a wide variety of vehicles. In the dampening disk assembly,a friction washer,is disposed between an input plate,and a hub flange,The friction washer,is engaged with the input plate,so that torque may be transferred from the input plate,to the hub flange,A cone spring,is disposed between the friction washer,and the input plate,in an axial direction to give resiliency to both members in the axial direction. A fixing plate,contacts the friction washer,in the axial direction. A spacer,is disposed between the fixing plate,and the hub flange,in the axial direction so as to transmit torque. A first gap is formed either between the spacer,and the fixing plate,in a rotational direction or between the spacer,and the hub flange,in the rotational direction.
