Definitions

  • the present invention relates generally to motorised bogies for railway vehicles.
  • the invention concerns a transmission for a motorised bogie with a motor-driven axle unit driven by an electric motor,supported by the frame of the bogie,through a transmission shaft one end of which is connected to the axle of the axle unit through a gearbox supported by the frame of the bogie or by the axle unit.
  • the gearbox contains a pinion rotatably supported in the said box and a gear wheel keyed to the axle and meshing with the said pinion, and the connection between the transmission shaft and the pinion is effected by a toothed coupling.
  • Transmissions of this kind are used, inter alia, on the motorised bogies of electric locomotives, the motor of which, supported by the bogie frame, has a hollow shaft, generally parallel to the axle of the axle unit, which is traversed axially, with clearance, by the transmission shaft.
  • the transmission shaft is coupled at one end, in a traditional manner, to the hollow shaft through the said toothed coupling, and at the other end to the said pinion through a flexible or articulated coupling so as to allow the necessary relative angular displacements between the axle and the hollow shaft of the motor.
  • the toothed coupling is therefore situated on the side opposite the gearbox, and is inserted within a suitable protective housing into which the appropriate lubricant is injected.
  • the object of the present invention is that of avoiding the said disadvantage and this object is achieved by virtue of the fact that in a transmission for motorised bogies of railway vehicles of the kind defined above, the said toothed coupling is fitted into the gearbox and is lubricated by the same lubricant as the latter.
  • reference numeral 10 indicates in its entirety one of the axle units of a motorised bogie, the axle 12 of which bearing the wheels 14 is connected by bushes to the frame, not shown in the drawings, of the bogie.
  • gear wheel 16 housed within a gearbox 18 articulated, in a manner known per se, to the bogie frame.
  • the gear wheel 16 meshes with a pinion 20 rotatably supported on roller bearings 22 within the gearbox 18.
  • Indicated diagrammatically at 24 is an electric traction motor supported by the bogie frame , the shaft of which, illustrated diagrammatically at 26, is disposed generally parallel to the axle 12 of the axle unit 10, and is hollow.
  • the shaft 26 is traversed, with radial clearance, by a transmission shaft 28, the end 28a of which, remote from the gearbox 18, is coupled to the corresponding end of the hollow shaft 26, by means of a coupling with elastic inserts, or an articulated joint 30, of traditional kind.
  • the other end 28b of the transmission shaft 28 is coupled for rotation with the pinion 20 by a toothed coupling 32 located within an appendage 34 of the gearbox 18.
  • the transmission of drive from the hollow shaft 26 of the electric motor 24 to the axle 12 of the axle unit 10 takes place through the flexible coupling 30, the transmission shaft 28, the toothed coupling 32, the pinion 20 and the gear wheel 16 which allows, during travel of the bogie, the necessary vertical,longitudinal and lateral movements of the axle unit 10 in relation to the hollow shaft 26.
  • lubrication of the toothed coupling 32 is effected by using the same lubricating oil as that used for the gears 16 and 20 circulating in the gearbox 18. This makes it possible to have better, more efficient, lubrication of the toothed coupling 22, and to avoid having to carry out additional lubrication level checks of the said coupling 32, as happens on the other hand in the case of known transmissions, described above, in which the toothed coupling is lubricated autonomously and separately.
