ABSTRACT:
A self steering axle system for motor coaches and similar commercial vehicles having a truss which hingedly supports an axle beam for pivotal movement between a normal positive caster angle and a negative caster angle when the vehicle is driven in reverse. The pivotal or rocking movement is achieved by a centrally positioned shift actuator acting through a yoke arm assembly and a latch which absorbs brake reaction forces. The system includes a caster lock for rendering the axle non-steerable in the event of a system failure or above predetermined operational speeds.
