ABSTRACT:
The torque variation absorbing device comprises a first flywheel, a second flywheel, a spring mechanism, a damping and torque limiting mechanism and a hysteresis mechanism. The hysteresis mechanism comprises a friction plate and a cone spring interposed between the first and second flywheels. The friction plate comprises a friction lining and a ring plate fastened to the friction lining. The ring plate has a connecting element to be connected with the first or second flywheel. A space is formed between the friction lining and the connecting element, and therefore, when the friction lining material is fastened, such as by hot-pressing or adhesive, to the ring plate, the space prevents friction lining material from flowing out before hardening and adhesive agent from spreading. In this arrangement of the device, when the friction force of the friction plate has worn the hysteresis mechanism is able to obtain a stable hysteresis.
