Each draw hook (11) on the left and right sides of the tractor vehicle towbar (14) coupling has a fixture (15a) for one end of a hydraulically damping piston cylinder (16). The cylinder is fitted on either side of the towbar and is pivotable horizontally and vertically. - Each piston cylinder is connected with its opposite end to the towbar via a link piece (17). The link is pivotable in the horizontal plane relative to the cylinder and the towbar, against the effect of a spring component (22). |
