Sažetak
The aim of this paper is to show an assessment process of two axle trailers steering mechanism’s influence on safety in curved trajectories. Safety is in first order considered through the envelope of trailers sides in curved trajectory and its tires path, in relation to the road’s edge. The assessment is based on numerical solution for trailer position w.r.t. time. The geometrical equations have been developed and solved in discretized time steps. A trailer with two axles with rigid front axle pivoting around a midrange axis and an Ackermann’s principle all-wheels steering trailer have been considered for a case study. Kinematics of the trailer’s path have been described by equations which are then discretized in time. The trailer’s cargo part’s envelope is one of the safety factors considered, while the second one is the tires path envelope w.r.t. the road edge. The results show that the all wheels steering offers more safety by the two considered criteria than the rigid front axle pivoting steering principle.
