ABSTRACT
This chapter analyzes results that have been obtained in a study of the directional dynamics and mechanics of heavy vehicle combinations employing full trailers. In a design synthesis context, the specialized models provide the type of information used in creating (developing) new designs and explaining them. More comprehensive models (and experiments with prototype vehicles) can then be used to quantify the expected performances of the new designs. Steering usually is controlled by a mechanical linkage driven by the yaw articulation motion between the dolly and the towing trailer. The controlled steering B-dolly retains the B-dolly drawbar construction, and therefore its critical roll coupling capability. It eliminates the yaw degree of freedom at the coupling to the first trailer, and it provides for control of the steer angle of the dolly tires as a function of the included angle between the two trailers.
