摘要： A linear steering truck apparatus (10) comprises a bolster member (20) having two ends. The bolster (20) is located along the transverse axis extending generally perpendicular to the longitudinal axis, and generally located between and parallel to the transversely extending axles (14,16). Side bearings 32,34 attach the linear steering truck (10) to the car body (12). A plurality of pedestals (26,27,28,29), each engages an axle bearing (30). The axle bearing (30) rotationally engages one end of a transversely extending axle (14,16). At least one pedestal (26-29) is movably attached to at least one other pedestal (26-29) situated in the same plane along the longitudinal axis. Steering component (90) is provided for performing car body steering, where the geometry of pivot points (63a,63b) from another axle to the bolster (20) forms a parallelogram. The pedestals (26-29) are pivotally connected so that a lateral force at one axle (14,16) is reacted by the other axle (14,16), wherein the car body (12) mass acts as a pendulum mass restoring force. The apparatus (10) is steered to the center of the track with either end of the truck leading after the trapezoid side yaws.
