摘要： An articulated air suspended hydraulic-dampened fifth wheel hitch coupling device for isolating the front of a fifth wheel or goose neck trailer hitch from the shock of bumps in the road and the inertia of movement of the trailer. Two inflatable air springs operatively connected to the pressurized air system of the tow vehicle eliminates vertical fifth wheel load from being transferred from the trailer to the tow vehicle. Additionally, an oscillating rocker connected transversely to the direction of travel of the vehicle allows the fifth wheel hitch to pivot in a transverse motion to eliminate load from being transferred from the trailer to the tow vehicle.
