Anti-binding motorcycle trailer hitch assembly |
摘要 |
A motorcycle hitch assembly is disclosed for attachment to a hitch support on a motorcycle for towing a trailer. The hitch assembly comprises a base and a pivotal trailer ball carried by the base for being coupled with the trailer coupling. The trailer ball includes a ball element and a ball shank extending from the ball element having a free end. A pivot support connects the base and the ball shaft so that the trailer ball and base pivot relative to each other generally in a vertical plane so that the trailer ball remains generally vertical as the motorcycle and base lean during turning. A clearance space defined between the free end of the shank and a bottom of the base allow the trailer ball to pivot freely in a vertical plane. Binding between the trailer coupler and the trailer ball element is reduced during turning.
