    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.

    Abstract: A fifth wheel coupling (4) for coupling a tractor (2) and a semi-trailer (3) of a tractor-trailer unit (1) comprises a coupling device arranged on the tractor (2) for receiving and arresting a king journal fastened to the semi-trailer (3). In order to achieve the best possible swiveling properties at a design of low complexity, there is provided as a fifth wheel coupling a ball-shape coupling (4) with a coupling ball (5) and an associated holding-down device (6) on the one hand and a ball cup (7) enclosing the coupling ball (5) in the coupling position and the attached butt part (8) on the other hand, with the coupling ball (5) and the holding-down device (6) replacing the coupling device and the ball cup (7) and the butt part (8) replacing the king journal.

    Abstract: A fifth wheel hitch (10) has a skid plate (28) pivotally mounted to a housing (18) for lateral pivotable movement. The hitch is closed with a sliding jaw plate and has a lock block (54) that optionally can affix the skid plate to the housing during towing of a trailer. Both the jaw plate (36) and lock block (54) are operated and set by a handle (20) that extends out of the side of the housing. The handle has a crank (21) that can both be rotated and pulled by the operator from the side of a pickup truck for convenience in operation to control both opening and closing the hitch and selectively setting the lock block.
