A trolley of a railway vehicle is made with possibility of arrangement thereon of a rig, a braking equipment, a spring suspension and two wheelsets consisting of an axle with pressed-in wheels, a brake disk and journal units, a bogie frame is formed by two longitudinal, with curved middle portion beams and one transverse beam connecting the middle parts of longitudinal beams together. The cantilever portions of longitudinal frame beams are interconnected by transverse cross-members of tubular section, whose end portions are rigidly fixed to the ends of longitudinal beams in the recesses that repeat the shape of traverse section, whereby each traverse is equipped with at least one braking mechanism, which is disposed in its the central portion and interacts during braking with its respective brake disk pressed-in onto the wheelset axle, whose journals are designed as a welded body, which is composed of a main portion of the tubular section and elements welded thereto. |
