Abstract
A clutch disk assembly is provided with a continuous variable hysteresis mechanism which reduces noises or vibrations of the driving system. The continuous variable hysteresis mechanism includes a plate member, a spring member and a friction lining member between the hub member and the disk member. A cam face is provided on one of the plate member and/or spring member, a projection on one of the spring member and/or the plate member. An engaging mechanism is positioned between the plate member and the hub member and the continuous variable hysteresis is generated between the disk member and the hub member.
Claims8
A torque transmitting clutch disk assembly comprising:
- hub means including a hub member and a hub flange extending radially of said hub member, said hub flange being arranged for limited rotation relative to said hub member;
- spring means acting circumferentially between said hub member and said hub flange;
- disk means coaxially and rotatably mounted to said hub member and disposed axially adjacent said hub flange;
- a first hysteresis mechanism axially resiliently arranged between said disk means and said hub member;
- and
- a second hysteresis mechanism axially resiliently arranged between said disk means and said hub flange, said second hysteresis mechanism including independently operable first and second hysteresis portions, said second hysteresis portion generating a continuously variable hysteresis and comprising:
- a plate member, a spring member and a friction lining member, said plate member provided with an axially open recess in which said spring member is positioned;
- a cam face formed on one of said plate member and said spring member;
- a projection formed on the other of said spring member and plate member and slidably contacting with said cam face;
- and
- an engaging member provided between said plate member and said hub member.
