DAMPER OF TORSIONAL OSCILLATIONS OF LOW STIFFNESS WITH CONTROL OF FRICTION TORQUE Russian patent published in 2010 - IPC F16F15/123 F16D3/14 F16D3/66 F16D7/02 

FIELD: machine building.

SUBSTANCE: damper consists of case, of external and internal hubs, of central helical spring and of multi-disk friction clutch. The central helical spring with its one end is attached to the case, while with the other one - to a flange of the internal sub. The friction clutch consists of disks with external splines and of disks with internal splines; friction bushings are installed between them. The central helical spring simultaneously functions for torque transfer and for compression of friction disks.

EFFECT: reduced amplitude of oscillations of transferred torque.
