Tramway guiding system, has two round faces whose diameter and shape are chosen in such way that one side roller has same speed as that of central roller at level of its running surface on rail

摘要

The system has a guiding roller device (1) with a central roller (24) and side rollers (25, 26) forming a side part. Diameter and shape of round faces (51, 52) that contact a guide rail (2) are chosen in such a way that one side roller in its contact zone (54) with the rail, at a level of its running surface on the rail, has same speed as that of the central roller.
