In each link plane there is either a pair of links moving symmetrically in opposite directions or an individual link. Each individual link is provided with two diagonally arranged shaft connections. Attached in the other diagonal direction in the additional application are two link forks which slide around two radial shaft journals. Both diagonals intersect and lie in the link plane. A further development of the basic idea is that all variants of the main application are additionally provided with an axial universal joint, these being formed around or within the group of links. <IMAGE>
