摘要： A trailer having a hitch assembly, intended to be used with a receiver on the towing vehicle, enables the vehicle/trailer pair to back up easily by locking the trailer's orientation relative to the towing vehicle. The vertical pivot axis (yaw) may be locked while the lateral (pitch) and longitudinal axes (roll) may remain free to rotate to allow for bumps and dips in the road. Furthermore a steerable suspension can be provided for many embodiments such as with an actuator receiving a signal from the back up wiring of the vehicle to change the mechanical constraints of the steering system upon receipt of the signal (such as to lock the position of a first tie rod connecting the wheels to the frame while freeing another, and possibly altering the angle of the wheels relative to the frame in the process). Meanwhile a toe-in effect of the wheels can be achieved by using multiple tie rods with a front tie rod bent rearwardly towards a rear tie rod.
摘要翻译： 具有牵引组件的拖车，旨在与拖车上的接收器一起使用，使车辆/拖车对能够通过相对于牵引车辆锁定拖车的方位而容易地备用。 垂直枢转轴（偏航）可以被锁定，而横向（俯仰）和纵向轴线（滚动）可以保持自由旋转，以允许道路中的颠簸和下降。 此外，可以为许多实施例提供可操纵的悬架，例如通过接收来自车辆的后备接线的信号的致动器，以在接收到信号时改变转向系统的机械约束（例如锁定第一 拉杆将轮子连接到框架同时释放另一个，并且可能在该过程中改变车轮相对于框架的角度）。 同时，通过使用具有向后朝向后拉杆向后弯曲的前拉杆的多个拉杆可以实现车轮的脚趾效应。
