Steering linkage in wheeled vehicle for steering the vehicle along guide rails

摘要

A first link member branched into two straight arms at a fixed angle is pivotally supported by the vehicle body at the branching point, and the free end of the first arm is linked with a connecting rod which in turn is connected to a steering arm for a road wheel while the free end of the second arm is pivoted to an end of a straight second link member which is equal to the second arm in length, the other end of which second link member is pivoted to a middle portion of a rod supporting at the ends thereof a pair of guide wheels. The rod is provided with means to move the rod relatively to the vehicle body thereby to retract the guide wheels and rotate the second link member until it forms no angle between the second arm.
