摘要： Wheelset guiding system for railway vehicle bogie, especially for freight car, which is composed from bogie frame (1) and at least two wheelsets (2) with wheels (2a), which are connected with the bogie frame (1) by swing arms (6), which are with the wheelsets (2) assembled by bearings (3) and bearings adapters (4) and obliquely positioned flexible elements (5) on bearing adapter interface (4b) and swing arms (6) are connected by joints (9) and by at least one bogie spring (10) with bogie frame (1), where on the swing arm (6) is arranged at least one bracket (6d) for flexible part (5) mounting and where on the swing arm (6) is arranged at least one guiding bracket (6a) pro the stabilization of the bearing adapter (4) position due to the surface (4c). Invention with advantage minimize hysteresis in the longitudinal movement of the bearing adapter (4) adjacent to the wheelset (2) and allows simultaneously optimize the conditions for stable run in straight track and conditions for wheelset (2) steering in curve by the optimised stabilization force between bearing adapter (4) and guiding bracket (6a) adjacent to the swing arm (6), which optimization is possible simultaneously by two parameters - by vehicle gravity and by position angle of flexible element (5) depending on the vehicle gravity, which effect is allowed due to the swing arm rotation (6).
