A fifth wheel apparatus for detachably coupling a trailing vehicle to a towing vehicle is disclosed. An equalizer bridge is supported on a towing vehicle and is pivotable about a roll axis that extends in a direction of towing motion. The equalizer bridge includes first and second arms that extend laterally from respective first and second sides of the roll axis. A fifth wheel head is coupled to the equalizer bridge for movement therewith about the roll axis. The fifth wheel head is pivotable relative to the equalizer bridge about a pitch axis transverse to the roll axis. First and second damping elements are operably interposed between the towing vehicle and the first and second arms, respectively. When the trailing vehicle is attached to the fifth wheel head, the first and second damping elements resist rolling movement of the trailing vehicle about the roll axis during travel over uneven roads. |
