Abstract

Studies conducted in the last 15-20 years, made significant additions to the under standing of the physical nature of the interaction of a pair of wheel-rail friction, however, and so far these is no clarity in the physics of the interaction between the solid-rolled and shrouded wheels and the rail head. Indicates a large amount ( ~ 20) the factors that affect the intensive wear of the wheels and rails. It notes that the overriding problems of wear factors in this case are harrowing gauge from 1524 mm to 1520 mm and a significant reduction in the surface of taper rolling locomotive and wagon wheels. In this article the result show a lack of validity of the taper reducing the rolling surface and locomotive wheels and narrowing the track on the wear rate. To significantly reduce the wear and tear as the rail head and the wheel slange, it is proposed to pass the increace in the surface of taper rolling locomotive and rail wheels on track 2i0 = 0,2 and restore a broadening of the same standards. It shows that the development of the ridge contacts is necessary to consider that the radius of the working fases of the rail to follow the profile of the wheel slange and smoothly into the surface profile riding the rail head, avoiding the emergence of two-point contact between wheel and rail.
