Abstract
The present invention relates generally to a linear steering truck apparatus comprising a bolster member having two ends, the bolster being located along the transverse axis extending generally perpendicular to the longitudinal axis, generally located between and parallel to the transversely extending axles, a linear steering truck attachable to the car body, a plurality of pedestals, a pedestal engaged to an axle bearing, the axle bearing being rotationally engaged to one end of a transversely extending axle, and at least one pedestal being movably attached to at least one other pedestal situated in the same plane along the longitudinal axis, and rack and pinion steering components, where the geometry of pivot points from one axle to the bolster form a trapezoid and the geometry of pivot points from another axle to the bolster form a parallelogram, the pedestals being pivotably connected so that a lateral force at one axle is reacted by the other axle, wherein the car body mass acts as a pendulum mass restoring force, and the apparatus being steered to the center of the track with either end of the truck leading after the trapezoid side yaws.
