  • Patent number: 7029059
    Abstract: 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.

  • Patent number: 7008168
    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.

  • Patent number: 6764270
    Abstract: A motor vehicle for industrial and/or agricultural operations, in particular an agricultural tractor, is described with an attachment interface containing a three-point implement hitch (24). In order to widen the spectrum of applications of the vehicle and the capability of the attachment interface and in order to open up new areas of application for the motor vehicle, a telescoping arm (16) that can be pivoted in the vertical direction is connected in a joint to the vehicle chassis (14). A support (22) is arranged at the free, extensible end of the telescoping arm (16) and carries the attachment interface for the three-point implement hitch (24). A locking arrangement (38, 40) is provided by which the support (22) can be immobilized with respect to the vehicle chassis (14), when the telescoping arm (16) is in an operating position.

  • Patent number: 6698524
    Abstract: 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.

  • Patent number: 6688403
    Abstract: 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.

  • Patent number: 6681880
    Abstract: 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.

  • Publication number: 20030217852
    Abstract: A hitch for a work vehicle includes a plurality of links pivotally coupled to a vehicle body and to an implement, either directly or indirectly via a hitch frame or quick coupler. The hitch preferably includes at least one upper link, two lower links and two longitudinally adjustable lift links for raising and lowering the hitch. Each lift link is coupled to an associated lower link near an aft end thereof. The hitch may selectively comprise both rigid and longitudinally adjustable links. The functionality of the hitch can be changed by replacing, adding or removing links. The hitch can be converted between a simple three-point hitch and a “hexapod” type hitch.

  • Patent number: 6581695
    Abstract: 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.
