DESIGN OF WHEEL TREAD FOR TWO-AXLE RAILWAY VEHICLE

In a railway vehicle having flexible supporting stiffness like a two-axle car with double link suspension, it is extremely important to prevent the body hunting occurred at a comparatively low running speed. As the results of fundamental research, a very effective method was developed for the prevention of body hunting, which method is to use an arcform wheel tread of worn profile and to give an adequate gravitational force between a wheel tread and a rail. By introducing the thought mentioned above, the N-shape tread for the wheel tread conformed the two-axle car having the double link suspension was exploited, the basis of its design was established, the theoretical analysis of hunting was carried out, and further the running test of actual cars was examined. The wheel having the N-shape tread, which is the result of this research, is utilized to all of the two-axle cars having double link suspension in the Japanese National Railways at present. (Author)
