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 ( 7 a) 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 tailend 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, 18 a , 19 ), which transmit exclusively vertical and transverse forces of the implement.
