A vibration-damping and oscillation-damping mounting system adjustably supports a vehicle cab on a vehicle chassis. The mounting system includes a plurality of variable-length links in the form of spring-damping elements (shock-absorbing elements) and/or adjusting elements. Preferably, the cab is supported on the vehicle chassis by at least six links, each having a first end coupled to the chassis and a second end coupled to the cab. The links are arranged in closed kinematic chains and with adjacent pairs of links arranged with convergently oriented axes so that active and/or passive shock absorption (spring damping) of the cab in six degrees of freedom is possible.

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.

Implement attachment interface for the coupling of operating implements to a utility vehicle and valve arrangement

A hitch for coupling an implement to a utility vehicle includes adjustable length coupling elements and a pivotal coupling unit coupled thereto. A control system automatically controls the length of the coupling elements to control the direction of the line of action of the draft forces, the position of the towing point defined by the coupling unit, and the orientation of the Implement relative to the utility vehicle. The control system includes sensors for sensing the position of the implement relative to the vehicle, for determining a set of reference positions, and for sensing forces applied to the coupling elements. The control system also automatically controls the length of the coupling elements as a function of the sensor signals.

Implement hitch and control system

A hitch control system controls a hitch for coupling an implement to a utility vehicle. The hitch includes longitudinally adjustable coupling elements operable to shift or pivot the implement in a lateral direction relative to the utility vehicle. A sensor, such as a wheel steering angle sensor, senses a parameter associated with lateral or turning movements of the vehicle. A control unit automatically adjusts the length of the coupling elements as a function of the sensor signals so that the position of the implement relative to the vehicle is adapted to the curved path. This reduces the outer radius of the area over which the vehicle and implement travel when traveling along a curved path and helps avoid collisions with objects.

Control system for a vehicle/implement hitch

A control lever controls movement of a system to be controlled. The control lever includes a manually operable handgrip attached to a platform. At least six connecting elements are arranged between the platform and a fixed console. Length sensors sense the length of the connecting elements, and/or force sensors sense forces acting on the connecting elements. A control unit evaluates the sensor signals and generates a control signal for controlling movement of the system. The connecting elements are be arranged in the form of a hexapod. The connecting elements may be telescoping members or rigid fixed length members.

A coupling system couples an implement to a utility vehicle, such as an agricultural or industrial vehicle, and includes a vehicle-mounted coupling frame and an implement-mounted coupling frame. The position of the vehicle-mounted coupling frame is adjustable by an adjustment mechanism. A position sensor senses the position of the implement-mounted coupling frame. An analysis unit determines the position of the implement-mounted coupling frame relative to the vehicle-mounted coupling frame. A control unit calculates a coupling motion path of the vehicle-mounted coupling frame. In response to a starting signal, the control unit causes the adjusting mechanism to move the vehicle-mounted coupling frame along the coupling motion path.

Vehicle/implement coupling system

An implement/vehicle hitch system for coupling implements to a utility vehicle includes two hydraulic cylinders for adjusting the position of the implement. The hydraulic cylinders are connected to a pair of motor/pump units which cause the hydraulic cylinders to operate in a synchronous manner.
