Abstract
The invention relates to rail vehicles. A four-axle bogie of a rail vehicle comprises a rigid frame of welded structure with side and transverse beams and four wheel sets with journal-boxes. The frame has one central and two end transverse beams. On the central transverse beam a step bearing with a roller device is placed. On each side beam elastic slides of constant contact are mounted. From the outer side on a bracket at least one spring is installed. Middle wheel sets have technological axial gaps in conjunction with pinions and are spaced at a distance selected to provide non-exceedance of the allowable stress in the main floor of the roadbed. End wheel sets have axial lengths combined with actuating journal-boxes. Each end and adjacent middle wheel sets are mutually approached. The total lateral stiffness of axle-box links holding each middle wheel set at horizontal movements is twice the transverse rigidity of links holding the end wheel set. The technical result is the improvement in mass and size while increasing load capacity.
