    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).

    摘要: The suspension of the railway bogie, particularly the freight bogie, comprised in a bogie that is equipped with a bogie frame (1) and at least two wheelsets (2) with wheels (2a) that are guided via swing arms (4) jointed to the bogie frame (1), the swing arms (4) and wheelsets (2) are assembled by bearings (3) and flexible bearing mountings (3a), the swing arms (4) are assembled with the bogie frame (1) by bushings (5) and by suspension spring assemblies (6) arranged between the swing arms (4) and the bogie frame (1), whereas to the suspension spring assembly (6) belongs the damping system, where intensity of damping effect depends on the load of the car, the damping comprises wedges (7) and friction leaf (8), at least on one side of the bogie the suspension is supported by a suspended equalization support (10) that is mounted on stabilization springs (11) that are arranged on the bogie frame (1), whereas the suspended equalization support serves as a wheel forces equalization mechanism for a bogie with the rigid bogie frame (1), where the longitudinal beams (1a) and cross beam (1b) are assembled via prestressed bolts (13).
