RUBBER-METAL DAMPER WITH POWER ARMATURE CHANGING GEOMETRY Russian patent published in 2012 - IPC F16F1/38 

FIELD: machine building.

SUBSTANCE: in the first variant the damper consists of flexible element which if necessary connected to the outer metal body due to the friction force and simultaneously nondetachably connected with internal metal sleeve and additional armature connected with each other. The additional armature can be made of plastics or composite material on its basis or of metal or alloy on its base. Additional armature is made in the form of segments connected with each other with strips so that the internal sleeve and additional armature create from the one side the comb the bottom of which is the surface of metal sleeve and the sides are the segments and strips of additional armature. At this the segments of additional armature can be located either radially or on the arc or crosswise or in combination in respect to its internal axis. In the second variant the flexible element of the damper is nondetachably connected to the outer metal body.

EFFECT: reduction of axial and/or radial movements of internal sleeve and increase of damper resistance to destroying loads and coaxial and/or face twisting.
