Elastic coupling especially for a torsional oscillation damping system comprises two halves enclosing center disk with two side disks, damping chamber and coupling elements,

摘要

The elastic, disk-type coupling has a first coupling half comprising two side disks immovably attached to the outer periphery. The second coupling half (2) has at least one center disk belonging to a hub and enclosed by the two side disks which are connected by elastic coupling elements (4) and form a sealed inner chamber. The radial outer part of the inner chamber contains at least one damping chamber with opening and filled with damping medium. Each coupling half has a cam (2.3,1.5) the second of which divides the damping chamber into two (6.1,6.2) part-chambers.
