  • Vehicle hitch with multi-directional damping
    Patent number: 7810831
    Abstract: The present invention is directed to a trailer hitch isolation assembly that attaches to the tongue of a fifth wheel trailer and that provides a moveable connection between a tow vehicle and the trailer. The hitch assembly includes a floating hitch attachment member such as a king pin, which is adapted to be attached to a tow vehicle. The hitch isolation assembly allows the hitch attachment member to move at least vertically relative to the tow vehicle to which the hitch assembly is connected. One or more air springs connect the floating hitch attachment to the frame of the trailer. These air springs permit relative movement between the attachment support member and the frame.
