The invention relates to rail vehicles and can be used in the undercarriage of a train, especially high-speed passenger transport. Novelty consists in that in a motor bogie each motor wheel pair comprises an axle, a single stage axial reduction gear, two wheels built-up on an axle, each of which has on a disc part two brake disks and two journal box units, each of which is equipped with a temperature sensor, in the case for connection of said reduction gear to a traction motor a gear coupling with arc teeth is provided, the frame is formed by two longitudinal beams curved down in the middle part, and one cross beam connecting the middle parts of the longitudinal beams to each other, and on the longitudinal beams elements are provided for retention of motor wheel pairs, on the transverse beam fasteners are provided for two traction electric motors and for dick brake equipment for each wheel, while in the middle of the cross beam a technological gap is made for location of the elements of lemniscate mechanism. Technical result: increase of speed limits of a railway vehicle by simultaneous reducing the mass of the frame, improving the reception and transmission of traction and braking effort and by improving the efficiency of braking. |
