Abstract

An elastic joint body for a shaft arrangement for the articulated connection of two shaft sections includes a plurality of bushings disposed in the circumferential direction at predetermined angular distances relative to a central axis of the joint body, a plurality of loop bundles, and a rubber elastic casing. Each loop bundle loops around two adjacent bushings and each bushing is looped by at least two of the plurality of loop bundles. Each of the plurality of bushings is provided with a plurality of bushing components. A first bushing component has an axial shaft section against which one of the loop bundles rests and wherein a second bushing component has a radial collar section against which the loop bundle rests. The first bushing component rests, without fixing, against the second bushing component in a contact zone offset relative to the loop bundle in the axial direction.
