Patent
CA 2372621
The invention relates to vehicle axles for fixed lorries and trailer vehicles having a supplementary axle system that is self-steering. Self-steering axle systems are known where the wheels are located on a pivotally mounted axle allowing the wheels to turn freely to follow the steered wheels. Known systems are adequate when the vehicle is moving in a forward direction, but have serious operational difficulties when the vehicle is being reversed. The object of the invention is to avoid said known difficulties, and the objective is met by a vehicle axle comprising a stub axle assembly mounted by a first pivot on a support, and the support being mounted on a second pivot on an axle beam, said support being provided with a means of causing it to pivot between two operational positions, and to hold the support in a required operational position, and said first and second pivots being disposed at a convergent angle whereby to set the first pivot at a first castor angle in one operational position, and at an equal and opposite second castor angle in the other operational position.
