  • Patent number: 9016711
    Abstract: A trailer having a hitch assembly, intended to be used with a receiver on the towing vehicle, enables the vehicle/trailer pair to back up easily by locking the trailer's orientation relative to the towing vehicle. The vertical pivot axis (yaw) may be locked while the lateral (pitch) and longitudinal axes (roll) may remain free to rotate to allow for bumps and dips in the road. Furthermore a steerable suspension can be provided for many embodiments such as with an actuator receiving a signal from the back up wiring of the vehicle to change the mechanical constraints of the steering system upon receipt of the signal (such as to lock the position of a first tie rod connecting the wheels to the frame while freeing another, and possibly altering the angle of the wheels relative to the frame in the process). Meanwhile a toe-in effect of the wheels can be achieved by using multiple tie rods with a front tie rod bent rearwardly towards a rear tie rod.

    Abstract: The present application describes a gooseneck coupler assembly that may include a gooseneck trailer pivot, an extension arm, and a pivot retention mechanism having a ball socket. The ball socket may engage with a hitch ball located on a towing vehicle. The gooseneck trailer pivot may be mounted on a towed vehicle or trailer and be capable of pivoting about a vertical axis relative to the trailer. During engagement, the ball socket and the extension arm may provide tilt capability but thereby prevent any rotational movement relative to the hitch ball. However, the gooseneck coupler assembly may still be able to tilt fore-and-aft or side-to-side relative to the hitch ball. Therefore, the only pivotal movement relative to a vertical axis would be permitted at the gooseneck trailer pivot.

  • Patent number: 7510205
    Abstract: The semitrailer is joinable to a tractor provided with a vertical towing gudgeon, is supported at its back end by a wheeled structure, and comprises a chassis having longitudinal members and crosspieces, which define a horizontal loading platform, and further having uprights rising from its forward end. A towing bar is hinged on the uprights around a first horizontal and transversal hinging axis. A compensating hydraulic cylinder is articulated between the chassis and the towing bar. A coupling is articulated to the towing bar forwardly of the first axis, for hinging around a second horizontal and transversal hinging axis, and is provided with a bushing that is transversal to the second hinging axis and is rotatably engageable on the towing gudgeon of the tractor.

  • Patent number: 7407175
    Abstract: A transporter for transporting a first person and one or more riders over a surface. The transporter includes a first support platform for supporting the first person, the first support platform having left and right sides and defining a fore-aft vertical plane and a lateral plane. At least one ground-contacting element is coupled to the first support platform such that the first support platform is capable of tilting in the fore-aft plane about a tilt axis. The at least one ground-contacting element is driven by a motorized drive arrangement so as to cause locomotion of the transporter. A controller commands the motorized drive arrangement. The controller is configured so that at least one of fore and aft sustained motion of the transporter is based at least on fore-aft tilting of the first support platform.

  • Patent number: 7380810
    Abstract: The present invention is directed to an adjustable trailer hitch that provides a suspended connection between a tow vehicle and an attached trailer. The hitch includes a support member that is adapted to be attached to a tow vehicle and a frame having first and second pivots for pivotally support a hitch plate, which is operative to connect to a trailer (e.g., engage a trailer pin). A first air spring has a first end fixedly connected to the support member and a second end fixedly connected to the frame. The air spring permits relative movement between the support member and the frame as well as transmitting towing forces therebetween. The air spring provides a pliable connection that at least partially mechanically isolates the trailer and the vehicle from each other. Instead of acting as a single unit, the vehicle and the trailer act at least partially independently of each other.

  • Patent number: 7032918
    Abstract: A method for stabilizing an articulated vehicle, which articulated vehicle comprises at least a front frame structure and a rear frame structure, and a frame joint structure, which is arranged to couple the frame structures to each other and to allow them to rotate both in relation to each other, away from the normal position, as well as at the same time around an axis, which is substantially parallel to the longitudinal direction of the articulated vehicle. In the method a supporting force is maintained, which force affects between the frame structures and resists the rotation of the frame structures away from normal position, and the maximum of said supporting force is controlled in such a manner that it is dependent on the difference of rotations at least when said difference is increasing and at least when said difference is static.

  • Patent number: 7000933
    Abstract: A method for attaching a carrier, such as a trailer, to a dynamically balanced transporter. The carrier is attached to the transporter with a pivot. The pivot axis of the carrier is coincident with the axis of rotation of the wheels of the transporter. This method of attachment minimizes the impact of the trailer on the ability of the transporter to maintain dynamic balance and control.
