Railway track and vehicle - has guide wheels for lateral steering of vehicle wheels in rail flanges

摘要

The transport vehicle system has a guideway with two horizontally spaced parallel rails, each with an upper horizontal flange on top of a vertical web. The vehicle (134) has a bottom support for movably supporting it on the upper flanges of the rails and guide wheels for lateral guiding engagement with the rails. Rigid discs (144,149) coaxial with the guide wheels (137,139) underlie the horizontal flanges of the rails and prevent vertical displacement of the vehicle from the rails. The rigid discs can be of smaller dia. than the guide wheels. The bottom support for the vehicle can be pairs of support wheels, each pair being mounted on a solid shaft, the axis of which is fixed relative to the vehicle.
