ABSTRACT:
A torsion damper has a viscous damping device, a dry friction damping device, two guide rings, a damper plate and a hub. The viscous damping device is arranged outside the zone which is bounded by the guide rings, and is confined within a housing comprising two housing portions which are movable with respect to each other. Mutual engagement structure which couples components together for simultaneous rotation, are provided between (a) the hub and one of the housing portions and (b) the other portion of the housing and that one of the coaxial parts of the damper which is not coupled with the hub for rotation therewith.
