Abstract

The coupling rod (3) can be adjusted for length by changing it a coupling rod joint parts and holder points in the undercarriage. A directional joint support bearing (2) is arranged in each of several openings (19) at the coupling rod joint parts and is fixed rigidly but releasably to the undercarriage by bolt pairs (17). The joint support bearing has a centring opening at its pressure side for a centring stub (8) arranged at a joint plate (4) with a guide wedge (9). The joint plate has a concave roller curve (5). A tension disc at the tension side corresponds to a ball joint extension (7). A spring (13) for tension forces is arranged after the ball joint extension and the disc has transverse cam followers (11) on either side of the spring to form a limited transverse cam follower.
