Abstract
A high speed transportation system designed to reduce frictional heat generated between the wheels and the track upon which the wheels are rotating in which a plurality of wheels are successively placed in contact with a track having a concave surface and removed therefrom so as to provide an "out of contact" period for cooling of the wheels. The concave surface of the track is provided with helically curved ribs which effect rotation of the carriage carrying the wheels thereby bringing the wheels successively into and out of contact with the rail.
Claims7
A transportation system comprising:
- a vehicle body;
- a plurality of shafts disposed around said vehicle body and supported thereby axially parallel to the direction of travel of said vehicle body;
- a plurality of tracks disposed around said vehicle body, a concave surface of each track being coaxial with an adjacent said shaft and including a plurality of helically curved ribs forming the running surface thereof;
- carriage means axially mounted on each of said shafts for rotation thereon;
- and
- a plurality of wheels rotatably mounted on each said carriage means having their axes of rotation in a single plane perpendicular to the axes of said shafts for successive engagement with and disengagement from said running surface of an adjacent said track.

A transportation system comprising:
- a vehicle body;
- at least one shaft disposed externally of said body and supported thereby axially parallel to the direction of travel of said body;
- at least one track adjacent said body, each said track having a concave surface coaxial with an adjacent said shaft and including a plurality of helically curved ribs forming the running surface thereof;
- carriage means axially mounted on each said shaft for rotation thereon;
- and
- a plurality of wheels rotatably mounted on each said carriage having their axes of rotation in a single plane perpendicular to the axes of said shafts for successive engagement with and disengagement from said running surface of an adjacent said track.
