Abstract: The single wheel trailer and stabilizing hitch assembly includes a hitch which precludes lateral tilt or roll of a trailer about the longitudinal axis of the towing vehicle and trailer, the trailer having only a single wheel for support. The hitch includes a pair of horizontal plates which bear against one another, with a vertical pivot pin securing the two plates together to allow the trailer to turn laterally relative to the towing vehicle. A separate horizontal pivot axis accommodates pitch of the trailer relative to the towing vehicle while negotiating bumps and dips. However, the trailer tongue is fixed relative to the roll axis of the assembly, and the trailer cannot tilt or lean to the side while being supported by its single wheel. This greatly reduces wheel bearing and tire wear, and reduces rolling resistance of the trailer as well. Different trailer configurations are also provided.

Abstract translation: 单轮拖车和稳定挂钩组件包括一个挂钩，其阻止拖车围绕牵引车辆和拖车的纵向轴线的侧向倾斜或滚动，拖车仅具有用于支撑的单个轮。 连接器包括一对彼此承载的水平板，其中垂直枢轴销将两个板固定在一起，以允许拖车相对于牵引车辆横向转动。 单独的水平枢转轴线可协调拖车相对牵引车辆的俯仰，同时协商颠簸和倾斜。 然而，拖车舌片相对于组件的滚动轴线是固定的，并且拖车在其单轮支撑的同时不能向侧倾斜或倾斜。 这大大减少了车轮轴承和轮胎的磨损，并降低了拖车的滚动阻力。 还提供了不同的拖车配置。
