ABSTRACT:
A trailer coupling for tractive vehicles, in particular agricultural tractors, consisting of two vertical guidance cheeks (7), fitted with lateral spacing to the rear of the vehicle, the guidance cheeks including vertical slots (7a) and a bearing member (11) held detachably at the lower end region of the guidance cheeks, on which a coupling member (12) is arranged for attaching an implement. In the case of a prior art trailer coupling, all forces transmitted from the attached implement to the coupling member used, a ball coupling (12) for example, are conducted via the bearing member (11) into the guidance cheeks (7). Thus this involves the undesirable necessity of having to dimension the guidance cheeks in a robust manner, which in turn leads to space problems within the tail end region of the vehicle. Therefore a trailer coupling is to be created which reduces the load on the guidance cheeks (7), when the forces of the attached implement are conducted into the rear of the vehicle. This is achieved by arranging the bearing member (11) to extend as far as a bearing block (10) fitted to the rear of the vehicle and connecting the bearing member to the bearing block (10) via at least one connecting element (17), which transmits dissipating forces of the implement exclusively in the vehicle's longitudinal direction. The bearing member (11) is also guided through the guidance cheeks (7) via further connecting elements (18, 18a, 19), which transmit exclusively vertical and transverse forces of the implement.
