ABSTRACT:
A fold bellows for rotating drive joints is proposed which, although it is equipped with a plurality of folds along its length, admits large bend angles without the flanks of its folds having mutual contract for a physical bellows dimensioning which corresponds approximately to a dimensioning of known fold bellows. For this purpose the fold bellows is equipped with a joint side fold of larger diameter, with a shaft side fold of smaller diameter and with at least one further fold which is provided at an axial interval from the two other folds and is smaller than the shaft side fold in diameter.
