Abstract
An inside ring (1) and an outside ring (2) are mounted about a common axis (3) and are joined to one another in a rotationally elastic manner by at least one elastic body (4) of elastomeric material. The elastic body (4) is bonded only to one of the rings (1, 2) and is supported in a relatively rotatable manner on the other ring (2, 1) by at least one friction layer (7) to limit the transmittable torque.
Claims26
Rotational vibration damper comprising
- a hub ring having an outside surface,
- a rotating ring outside of said hub ring and having an inside surface concentric to said outside surface of said hub ring,
- a friction layer fixed relative to one of said inside surface and said outside surface,
- an elastomeric body fixed relative to the other of said inside surface and said outside surface, and supported by said friction layer so that said rotating ring rotates with said hub ring unless slippage occurs at said friction layer, and
- a bearing situated between said hub ring and said rotating ring.

Rotational vibration damper comprising
- a hub ring,
- a rotating ring disposed concentrically with said hub ring, said rotating ring having a radially inner limb and a radially outer limb of larger diameter than said inner limb,
- an elastomeric body between said hub ring and said outer limb and fixed to one of said hub ring and outer limb,
- a friction layer between said elastomeric body and the other of said hub ring and said outer limb, said friction layer being fixed relative to one of said elastomeric body and the other of said hub ring and said outer limb, and
- a bearing disposed directly between said inner limb and said hub ring.

A rotational vibration damper comprising
- an inner tubular ring,
- an outer tubular ring situated concentrically to said inner tubular ring,
- an elastomeric body fixed to said inner tubular ring between said inner tubular ring and said outer tubular ring,
- an angular piece having a tubular portion fixed to said elastomeric body between said elastomeric body and said outer tubular ring, and a radial flange spaced axially from said outer tubular ring,
- a friction layer fixed to one of said outer tubular ring and said radial flange, said friction layer being disposed under axial bias against the other of said outer tubular ring and said radial flange, and
- a friction sleeve disposed directly between said inner tubular ring and said outer tubular ring, said friction sleeve being axially remote from said elastomeric body.
