Vehicle trailer rear axle steering mechanism - has telescopic longitudinal torsion bar connected to steering forks to manipulate trailer rear axles

摘要

The trailer circular mounting plate has a slider lever near the circumference and rotation of the plate produces angular motion of the lever for angular movement of a cross lever. Ropes attached to the cross lever pass over guide pulleys at 90 deg. and are attached to the circumference of a vertical disc. The outer section of the telescopic torsion bar is attached to the disc, the inner section slides inside the outer section on guide bearing blocks. A lever attached to the end of the inner section at the rear of the trailer connects with a steering fork for the rear axle. Other axles can be similarly steered by a lever connection between axles or by duplicating the steering fork mechanism.
