Definitions

  • the present invention relates to a suspension for a chassis with at least two axles of a railway vehicle, such as a wagon.
  • suspension in the present description means the partly deformable mechanical means which connect the axles to the chassis, the latter possibly being as well that of a wagon with at least two axles as that of a bogie articulated to the frame of a wagon with several bogies.
  • the present invention also relates to a chassis provided with this suspension.
  • each axle mounted at each of its ends in an axle box, is held perpendicular to the axis of the chassis by spring systems provided with damping means which each connect a axle box to chassis.
  • each axle box supports the chassis by means of at least two helical compression springs mounted on either side of the axle.
  • a spring is compressed between the axle box and a bonnet on which part of the wagon's weight is exerted.
  • the axle chassis while the bonnet is biased obliquely downwards via an articulated member connected to the chassis.
  • the axle box is frictionally mounted between a flat reference face of the chassis and a pusher actuated by the bonnet which tends to apply the axle box against the reference face due to the obliquity of the stress due to the articulated organ.
  • This assembly simultaneously ensures the damping of the oscillations of the springs and the rigorous positioning of the axle perpendicular to the axis of the chassis.
  • FR-A-1 072 207 describes a suspension which conforms to the preamble of claim 1 and which remedies the drawbacks stated above.
  • the two flanges are traction flanges which are arranged symmetrically when the vehicle is traveling in a straight line, the axle box then having an average position between two longitudinal travel limits.
  • This arrangement has two drawbacks. Indeed, the straight line position does have a certain stability because as the axle deviates from it on one side or the other, there appears an increasing return effort, but this stability is not exemplary and we can see some yaw effects in a straight line. On the other hand, the increasing return force considerably hinders the axle when it has to take strong orientations in tight curves.
  • the object of the present invention is to remedy these drawbacks by proposing a suspension in which the axles have a more stable straight line position while negotiating tight curves more easily.
  • the difference in inclination between the flanges is the cause of a restoring force urging the axle box against the reference face.
  • the axle in a straight line, the axle is in a position well determined by the reference face. To remove it, it is no longer enough for a small disturbance, it takes an effort exceeding the effort threshold determined by the difference in inclination between the flanges. The axle is therefore very stable in a straight line. When cornering, such an effort exceeding the aforementioned threshold appears.
  • the combination of the traction flange and the compression flange means that the initial difference in inclination between the flanges is kept appreciably when the axle box deviates from the reference face.
  • the elastic means comprise at least two springs mounted on either side of the axle, at least one spring on each side of the axle is located between the box and a cap connected to the chassis by the connection flanges .
  • the two-axle chassis provided with a suspension of the above kind is characterized in that this suspension equips the two axles of the chassis, the articulated flanges mounted in traction and in compression occupying in the two axles in substantially symmetrical positions relative to the transverse median plane of the chassis.
  • the two axles of the chassis can be oriented relative to the chassis as a function of the curvature of the track, which limits the angular deviations of the axles relative to the chassis; in addition, the chassis behavior is sensitive identical depending on whether the wagon travels in one direction or the other on the railway, which is particularly interesting in the case of railway equipment.
  • the bogie shown in FIGS. 1 to 3 comprises a chassis which comprises two longitudinal members 1 connected by a central cross member 32 and two end cross members 2 constituting with the longitudinal members 1 a frame carried by four wheels 3 coupled in pairs by means of two axles 4.
  • Each axle 4 is connected at its two ends to the chassis by means of a suspension 6 situated beyond the corresponding wheel 3 relative to the middle of this axle 4.
  • each axle 4 is carried at its two ends by an axle box 7 in which are housed the ball bearings which allow the rotation of the axle 4 relative to the chassis.
  • the axle box 7 has two bases 8 directed on either side of the axle 4 at a distance below the beam 1, and on each of which rests the lower end of a helical suspension spring 9.
  • the springs 9 are compressed between these two bases 8 and two caps 11, 12 connected to the chassis and on which is exerted, in service, part of the weight of the wagon.
  • each of the caps 11, 12 is connected to the spar 1 by a pair of connecting flanges 13 or 14.
  • the two flanges 13 or 14 of the same pair are mounted in parallel and articulated to the cap 11 or 12 corresponding which, for this purpose, carries laterally two opposite pins 16 with an axis substantially parallel to the axle 4.
  • the flanges 13 constitute connecting rods mounted in compression between the cap 11 and the chassis 1. From the pin 16, the flanges 13 are directed opposite the base 8 and are fixed on an axis 17 which is articulated on the side member 1.
  • the flanges 14 are rings mounted in traction between the cap 12 and two ears 18 integral with the spar 1. These ears 18 are formed at the end of a wing 19 with a U-shaped section starting from the spar 1, directed towards the base 8; they extend the legs of the U, which are turned towards the spring 9, and thus come from either side of the latter.
  • Each flange 14 is articulated to the ear 18 by means of a pin 21, carried by this ear 18, directed towards the outside of the wing 19 in a U, with an axis substantially parallel to the axle 4, and more close to the base 8 that the pin 16 of the cap 12.
  • the distance between the pins 16 of the cap 11 of the axis 17 is greater than the distance between the pins 16 of the cap 12 of the pins 21 .
  • the line XX ' which joins the axis 17 and the pin 16 of one or other of the flanges 13 and the line YY' which joins the pins 16 and 21 of the flange 14 which faces are inclined in opposite directions to each other with respect to the axis ZZ 'of the springs 9 which is substantially vertical when the bogie is in the service position on a horizontal railway track, and converge downwards, at below the axle box 7.
  • the angle of inclination B of the line YY ' is greater than the angle of inclination A of the line XX' relative to the axes ZZ 'in the example shown.
  • the pushers 23 include a tail 24 whose end rests against the caps 11, 12, and which is mounted to slide in a bore 26 formed in the base of the U of the wing 19 for one of the pushers 23, and, for the other pushbutton 23, in a wing 22 integral with the spar 1 and facing the base of the U of the wing 19 on the other side of the axle box 7.
  • the pushers 23 also include a head 27 whose front face, which is flat, bears on the flat lateral faces also of the axle box 7.
  • Friction linings 28, 29, for example made of manganese steel, are welded to the front faces of the heads 27 of the pushers 23 as well as to the flat side faces of the axle box 7.
  • the pushers 23 cannot sink into the bores 26 beyond a fully retracted position in which the rear face of their head 27 is in abutment against a boss 31 which opens each of the bores 26 on the side of the box. axle 7.
  • the bogie shown in Figure 1 has at the two ends of each of its axles 4 a suspension of the kind just described.
  • the mounting of these suspensions is symmetrical by relative to the transverse median plane of the bogie, so that for each suspension, the flanges 13 which work in compression are associated with the spring 9 situated opposite the other axle 4 relative to the axle box 7 considered and have a less inclination than the flanges 14 which work in traction.
  • the axes of the pushers 23 are located in the same plane as the axes of the pins 16 of the caps 11,12. Furthermore, the distance D (FIG. 5) remaining between the rear face of the head 27 of the pusher 23 associated with the cap 12 and the corresponding boss 31 determines the maximum lateral stroke of the axle box 7, relative to the chassis. In the case of a bogie, the distance D can be, for example, 12 mm.
  • axle box 7 takes oscillations relative to the chassis which are damped by the friction of the linings 28 of the pushers 23 on the linings 29 of the axle box 7.
  • This effect exerts on the axle 4 a torque which tends to press more the axle box 7 outside the curve against the pusher 23 which is already in the retracted position, and tends to bring the other axle box 7 towards hat 12.
  • the flanges 13 and 14 have pivoted around the axis 17 and the pins 21 so that the cap 11 is also slightly raised towards the beam 1 while the cap 12 has, on the contrary, slightly approached the base 8.
  • This property constitutes one of the important advantages of the suspension in accordance with the invention because it allows the axles to fit into tight curves without it being necessary to exaggerate the force applied to the boxes 7 by the wheels 3.
  • the suspension according to the invention thus makes it possible to simultaneously ensure the damping of the oscillations and the orientation of the axle 4 with a very small number of parts.
  • the invention also achieves an excellent compromise between a rigorous positioning of the axles 4 in a straight line and an orientation of the axles 4 in a curve resulting from relatively moderate forces.
  • the flanges working in traction could be associated with the spring opposite to the other axle of the chassis relative to the axle box considered, and be less inclined than the flanges working in compression.
