ABSTRACT:
The disclosure relates to a means of coupling a trailer to an automobile comprising a self-aligning and shock-absorbing coupling means. The coupling means uses a fifth wheel and spring-loaded roller-detent means to maintain alignment in yaw between the vehicle and the trailer. A speed-responsive means reduces the "stiffness" in yaw between the automobile and the trailer when the vehicle speed is below a predetermined value.
