Wheel for the mobile material of a convex profile, without flange, on the rail of a concave profile in railways where appliances of railways are mounted without needles and cross bars

摘要

Convex profiled wheel with no rib bearing for moving objects, on a concave profiled rail, on railway tracks with lines without points or crossings, the technical solution for which is valid for any existing state of the art gauge of track or others designed or created in the future; recommended for tracks specialising in the carriage of passengers at a high velocity with a predominantly straight permanent way and, exceptionally, curved sections with a radius not less than 10,000 metres with rails without points or crossings with a radius of 3,000 millimetres. The technical solution permits an interaction between the moving object and the superstructure of the track and is characterised by the shape of the wheel, whose convex, symmetric profile, with no butt, core or shoe.IMAGE
