The paper contains results of research of the driving resistance reducing of a railway vehicle by the modification of a railway wheel construction. The perspective railway wheel construction allows the possibility of the relative rotation of the guiding and supporting wheel surface. Based on current research of experts and specialists in the field of the railway transport and taking into account existing requirements and standards several technical solutions of such a wheel are developed. There are also presented results of stress and strain analyses of these technical solutions. Based on obtained data it is possible to conclude that proposed construction solutions meet requirements for the safety factor.

The article deals with the effectiveness of reducing the level of force interaction of the rail vehicle wheels with rails in curved sections of the track through the use of mechatronic position control systems for wheel pairs in the rail gauge in the horizontal plane. The approaches to the creation of such a mechatronic system operating on the principles of fuzzy logic are described. To determine the angles of attack of wheels on the rails, it was proposed to use the acoustic emission indicators of the contact of the wheel with the rail. To determine the direction of curvature of the rail track, it is advisable to use data from navigation systems. The study of the dynamics of the rail vehicle during the passage of a curved section of the track in real time was carried out using the Matlab/Simulink software package. The proposed mechatronic control system for the position of the wheel sets in the horizontal plane allows to ensure their optimal installation under various driving conditions in the rail gauge. This makes it possible to minimize the angles of attack of the wheels and reduce the forces of the horizontal interaction of the wheels with the rails.
