1. Low friction saddle coupling for use in coupling a trailer (3) to a tractor vehicle (1) comprising a coupling plate (2) mounted on the tractor vehicle, the surface of the coupling plate being covered by an antifriction layer (6) and slidably interacting with a slide plate (4) attached to the trailer (3) for supporting the vertical forces, the free surface of the slide plate being provided with a gliding inset, in operation remaining in a fixed position relative to the surface, characterized in that the gliding inset is a steel plate (7), the free surface of which is machined to a maximum roughness of 1 mu m and which has a bore for permitting passage of the king journal (5), the diameter of which allows said passage with minimal clearance, and that there is no further connection between the steel plate (7) and the slide plate (4). |
