Definitions

  • the present invention relates to a traction vehicle, in particular a rail vehicle, comprising at least one chassis bogie in which at least one geared motor is arranged and carries, more particularly, on a traction vehicle motor bogie.
  • the bogie of a railway vehicle performs lateral movements of translation and rotation, known under the name of sinusoidal step, even on an absolutely straight and flat path.
  • the forces exerted by this sinusoidal step on the bogie frame and the resulting oscillation frequencies increase with increasing vehicle speed.
  • the speed called critical is that at which the natural frequency of the bogie is close to the resonance.
  • the frequency with which the truck vibrates is higher as the speed of the vehicle is high.
  • a motor bogie has a very low non-suspended mass so that its moment of inertia is low with respect to the translations perpendicular to the direction of travel as well as with respect to rotations around it. of its vertical axis.
  • the geared motor is rigidly fixed in the frame of the bogie.
  • a shaft which is preferably hollow, in this case advantageously assumes the transmission of energy from the reduction gear train to the wheels via the axle.
  • a cardan shaft provides power transmission from the gearbox to the driven wheels via a second gear train mounted on the axle.
  • the contraction and extension movements of these telescopic gimbals reveal friction forces 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 gimbal.
  • EP-444016 discloses a motor truck according to the preamble of claim 1.
  • the object of the invention is to provide a traction vehicle engine bogie as specified, but improved so that the lateral displacements of the bogie frame are limited and the so-called critical speed is increased.
  • the subject of the invention is a bogie according to claim 1.
  • the principle of the invention is based on the fact that the lateral movements of the geared motor and the inertia put into play play the role of a drummer, especially when running at high speed or when passing on a shock such as les turnouts for example.
  • the bogie frame then undergoes, as indicated above, lateral shocks may cause the instability of the vehicle and the derailment thereof.
  • the inertia and the elastic transverse displacement of the geared motor unit in the bogie frame oppose the movements of the bogie frame under the effect of shocks.
  • the geared motor dampens these movements through a phase shift between the movements of the bogie frame and the geared motor.
  • the vibration damper makes it possible to reduce the clean motions of the geared motor unit.
  • 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 in rotation between the body and the bogie, unlike some system where part of the geared motor unit is suspended under the body.
  • the motor bogie of the invention may also satisfy at least one of the features of the dependent claims 2 to 4.
  • 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 are placed two driving wheels 2.
  • An axle 20 connects the drive wheels 2.
  • a chassis 4 of the bogie is supported by means of springs 3 on axle boxes 11.
  • a drawbar 5 arranged in the middle of the bogie frame provides the connection between the bogie frame and the body.
  • a geared motor 6, 10 comprising a motor 6 and a gear 10 is disposed inside the bogie frame 4.
  • the suspension of the geared motor 6, 10 to the bogie frame 4 is provided by three elastic rods 7, 8, 9.
  • the rods 7, 8, 9 are articulated to the frame 4 and the geared motor 6, 10 along axes parallel to the direction of travel or longitudinal direction of the chassis 4 bogie. This direction of travel corresponds to the direction of lane 1.
  • the rods 7, 8 and 9 are substantially of the same length.
  • the connecting rod 9 is arranged in the alignment, in the longitudinal direction, of the rod 8.
  • the rods 7 and 8 are arranged substantially at the same level in the same plane orthogonal to the longitudinal direction.
  • the geared motor 6, 10 can move transversely to the longitudinal direction, that is to say in a plane substantially orthogonal to it, relatively relatively, by rotary translation.
  • the gear 10 is clamped on the motor 6 and comprises a pinion 15 set on the motor shaft, an intermediate wheel 16 and a ring 17 which are shown schematically.
  • a hollow transmission shaft 18 transmits the rotational energy of the ring 17 directly to the axle 20.
  • a damper 12 oriented transversely to the longitudinal direction, is fixed between the bogie frame 4 and the geared motor 6, 10.
  • the geared motor 6, 10 will translate automatically opposite the transverse displacements that the frame 4 tends to undergo.
  • the geared motor 6, 10 therefore plays the role of inertial drummer by limiting the transverse displacements of the frame 4 and thus increasing the so-called critical speed of the bogie and the vehicle that is equipped.
  • the freedom of movement in transverse translation of the geared motor 6, 10 must be large enough that its transverse movements are likely to limit those of the chassis 4.
  • the geared motor 6, 10 can translate 15 mm on either side of a rest position in which the rods 7, 8 and 9 are vertical.
  • the geared motor 6, 10 can translate with an overall lateral travel of 30 mm.
  • the damper 12 absorbs the own vibrations of the geared motor 6, 10 due in particular to its operation.
