Definitions

  • the present invention relates to a traction vehicle, in particular a railway vehicle, comprising at least one chassis bogie in which at least one geared motor is arranged and relates, more particularly, to a traction vehicle bogie
  • the bogie of a railway vehicle performs lateral movements of translation and rotation, known under the name of sinusoidal walking, even on an absolutely straight and flat track
  • the forces exerted by this sinusoidal walking on the bogie frame and the frequencies of the resulting oscillations increase with the increased vehicle speed
  • the speed called critical is that at which the natural frequency of the bogie is close to resonance. The higher the frequency at which the bogie vibrates, the higher the vehicle's running speed. It is imperative, in vehicles intended to travel at high speed, in particular in railway vehicles, to increase the so-called critical speed by special structural arrangements to allow stable walking
  • the gear motor is rigidly fixed in the chassis of the bogie.
  • a shaft which is preferably hollow, in this case advantageously assumes the transmission of energy from the train. reduction gear to the wheels via the axle
  • a cardan shaft ensures the transmission of energy from the reduction gear to the wheels driven by means of a second gear train mounted on the axle.
  • the contraction and extension movements of these telescopic gimbals reveal forces of friction which are a function of the torque to be transmitted and which slow down the movement
  • the weight of the telescopic shaft is necessarily greater than an undivided universal joint
  • the aim of the invention is to provide a motor bogie of a traction vehicle as specified, but improved so that the lateral displacements of the bogie chassis are limited and the so-called critical speed is increased
  • the geared motor unit is suspended in the bogie frame with three elastic rods so as to be sufficiently mobile transversely to the longitudinal direction of travel of the vehicle to play the role of flywheel
  • a shock absorber fixed between the bogie chassis and the geared motor makes it possible to absorb the vibrations of the geared motor.
  • the principle of the invention is based on the fact that the lateral displacements of the geared motor and the inertias involved play the role of '' a drummer, especially when walking at high speed or when passing over an impact such as switches for example
  • the inertia and the elastic transverse displacement of the geared motor group in the bogie chassis oppose the displacements of the bogie chassis under the effect of shocks.
  • the geared motor absorbs these displacements thanks to a phase shift between the movements of the bogie chassis and the gear motor
  • the vibration damper makes it possible to reduce the proper movements of the gear motor group
  • Another advantage of the motor bogie according to the invention is the complete independence of the bogie, both at the level of the mechanical interfaces and at the level of the dynamic couplings in alignment and rotation between the body and the bogie, unlike some system where part of the gear motor unit is suspended under the body
  • the motor bogie of the invention can also satisfy at least one of the following characteristics
  • said motor-reducer is movable in translation transversely to the longitudinal direction of travel of said vehicle to play the role of flywheel
  • said motor-reducer is movable in translation with a lateral stroke of at least 30 mm
  • said gear motor is suspended on the axle side from said bogie chassis by a link and, on the engine side, from said bogie frame by two links,
  • said gear motor is suspended from the axle side to said bogie chassis by two rods and, from the motor side to said bogie chassis by a rod
  • the invention also relates to a traction vehicle which comprises at least one motor bogie as defined above.
  • the single figure illustrates a track 1 on which two driving wheels are placed 2
  • An axle 20 connects the driving wheels 2
  • a bogie chassis 4 is supported by springs 3 on axle boxes 1 1
  • a drawbar 5 placed in the middle of the bogie chassis provides the connection between the bogie chassis and the body
  • a motor-reducer 6, 10 comprising a motor 6 and a reducer 10 is disposed inside the bogie chassis 4
  • the links 7, 8, 9 are articulated to the chassis 4 and to the geared motor 6, 10 along axes parallel to the running direction or longitudinal direction of the bogie chassis 4 This walking direction corresponds to the direction of the track 1
  • the links 7, 8 and 9 are substantially the same length
  • the link 9 is arranged in alignment, in the longitudinal direction, of the link 8
  • the links 7 and 8 are arranged substantially at the same level in the same plane orthogonal to the longitudinal direction
  • the gear motor 6, 10 can move transversely to the longitudinal direction, that is to say in a plane substantially orthogonal thereto, relatively significantly, by rotary translation
  • the reduction gear 10 is flanged on the motor 6 and comprises a pinion 15 wedged on the motor shaft, an intermediate wheel 16 and a crown 1 7 which are shown diagrammatically
  • a hollow transmission shaft 18 transmits the energy of rotation of the crown 17 directly to the axle 20
  • a damper 12 oriented transversely to the longitudinal direction, is fixed between the bogie chassis 4 and the geared motor 6, 10
  • the chassis 4 When a vehicle equipped with a bogie thus formed travels on track 1, the chassis 4 is subjected to transverse forces, for example under the effect of shocks, which tend to induce transverse displacements of the chassis 4 as indicated in the preamble to the description
  • the geared motor 6, 10 will automatically translate opposite to the transverse displacements that the chassis 4 would tend to undergo
  • the geared motor 6, 10 oscillates transversely in phase opposition with respect to the bogie chassis 4
  • the geared motor 6, 10 therefore plays the role of flywheel by limiting the transverse displacements of the chassis 4 and therefore by increasing the so-called critical speed of the bogie and of the vehicle which is equipped with it.
  • the freedom of movement in transverse translation of the geared motor 6, 10 must be sufficiently great so that its transverse movements are capable of limiting those of the chassis 4
  • the gear motor 6, 10 can translate by 15 mm on either side of a rest position in which the connecting rods 7, 8 and 9 are vertical.
  • the gear motor 6, 10 can translate with an overall lateral stroke of 30 mm
  • the shock absorber 12 absorbs the natural vibrations of the gear motor 6,
