Abstract

An elastic joint body for a shaft arrangement for the articulated connection of two shaft sections, comprising a plurality of bushes (12) disposed in circumferential direction at predetermined angular distances in relation to a center line of the joint body, a plurality of loop assemblies (22, 24, 26), wherein each loop assembly (22, 24, 26) is looped around in each case two adjacent bushes (12) and at least two loop assemblies (22, 24, 26) are looped around each bush (12), a support device (10) that is disposed for axially guiding the plurality of loop assemblies (22, 24, 26) on at least one of the bushes, and a rubber-elastic sheath, into which the loop assemblies (22, 24, 26), the support device (10) and the bushes (12) are at least partially embedded. According to the invention it is provided that the support device (10) comprises two axially outer shoulder elements (14, 16), which may be fitted on one of the bushes (12) and against which at least two of the loop assemblies (22, 24, 26) to be guided are positioned, wherein between said assembly loops (22, 24, 26) at least one axially inner intermediate disk (18, 20) is disposed on one of the bushes (12) and is disposed at an an…
