ABSTRACT:
An implement attachment interface is described, that is used for the coupling of operating implements to a utility vehicle, and that contains six double-acting hydraulic cylinders, that are adjustable in length and which are arranged in the manner of a hexapod between the utility vehicle and a coupling frame. This contains two upper hydraulic cylinders that are arranged alongside each other and extend in a direction converging towards each other, two lower hydraulic cylinders arranged alongside each other and converging towards each other as well as two hydraulic cylinders at the sides. According to the invention means are provided that for a pendulous movement to the right the lower right hydraulic cylinder and the upper left hydraulic cylinder extend synchronously and the lower left hydraulic cylinder and the upper right hydraulic cylinder are retracted synchronously. For a pendulous movement to the left the hydraulic cylinders operate in the opposite direction. Upon a deflection of the implement to the side the result thereby is in each of the diametrically opposite upper and lower hydraulic cylinders a simultaneous and equal change in length. Thereby the hydraulic cylinders interacting in this movement experience retraction strokes that are equal to the extension strokes.
