Abstract
A steerable dolly for a truck trailer resting thereon comprising a steering linkage to turn the dolly wheels relative to the dolly frame, the linkage including an engagement with the trailer that senses the yaw articulation angle of the trailer relative to the dolly frame and causes the linkage to steer the dolly wheels in response to the yaw articulation angle. The steering ratio of the dolly wheels to the yaw articulation angle is a function of the dolly tow bar length for a B-Dolly configuration, the rear overhang of the towing vehicle and the wheel base of the trailer resting on the dolly fifth wheel. The steering ratio may be adjusted by adjusting the effective length of one of the links in the steering linkage.
