Abstract
The wheel aims to replace traditional railway wheels which are constructed by giving the rim a projecting profile, known as the flange, which is the object which carries out guiding functions, under the forces generated by its frictional contact with the rail. Given that the points of double contact of the running rim and of the guide flange are on circles of different diameter, their tangential speeds do not have the same value, which is reflected in a grinding frictional contact between flange and rail which gives rise to severe wear on both. This patent solves the problem by constructing the wheel as two independent elements or bodies, that corresponding to the flange being loose.
