Definitions

  • This patent relates to a guided vehicle with steerable axles according to French Patent No. 2,526,387 in which a radial guidance of the axles is produced.
  • This vehicle is constituted by a body carried by two axles each provided with two wheels and comprising, at the level of each axle, a cross member which pivots about an axis relative to the body and which carries the axle and a bar of hitch articulated around a point on the body and in contact at another point with the crossmember whose rotation angle it controls, the distance a between said axes of rotation of the two crossmembers of a vehicle, the distance n between the hinge point of a drawbar and the axis of rotation of the corresponding cross member, the distance b between this axis of rotation and the point of contact of this drawbar and the cross member and the distance d between the end of the drawbar and its articulation point substantially verifying the following relationship:
  • suspension elements are interposed between each axle and the crosspiece which carries it.
  • Railway vehicles can be subjected to a rolling movement which is a small amplitude oscillation around a central longitudinal axis parallel to the track, this rolling movement can be maintained by the imperfections of the track on certain of its sections.
  • Another factor which risks also creating a loss of radiality is the sliding of at least one wheel on the rail when one is in a curve for example, owing to the fact that the two wheels are integral with the axle.
  • the vehicle according to patent FR-A-2 526 387 does not allow radial guidance of the end axles of a train of vehicles since the guiding of an axle is carried out in conjunction with the guiding of the axle neighboring the next vehicle.
  • French patent 1,153,641 describes a device which has been known for a long time for carrying out radial guidance. According to this patent, in order to avoid the forces due to roll, the drawbar is fixed to the body by a rotary element allowing a slight twist which avoids the forces due to the roll movement.
  • the object of the present invention is to remedy these drawbacks and to allow radial guidance of the axles in all circumstances as well as radial guidance of the end axles, thanks to a specific arrangement of the point of attachment of the drawbar to the body. .
  • the point of attachment of the drawbar to the body is substantially arranged on the roll axis of the vehicle. Thanks to this arrangement, the rolling movement no longer causes the attachment point of the drawbar to move and the radiality of the guide is preserved.
  • the attachment points of the suspension elements interposed between each axle and the cross member which carries it are arranged at a level sufficiently high for the roll axis to pass substantially through the point of hitch bar attachment.
  • each driving axle has independent wheels as well as a device for limiting the slip between the two wheels.
  • This slip can for example be limited to 5%.
  • This latter arrangement makes it possible to eliminate the forces due to the sliding of the wheels on the rails for example in a curve and consequently to maintain the radial guidance of the axles.
  • each axle comprises an electronic device for controlling the speeds of each of the wheels and for acting on the braking members to restore the equality of the resistant torques on each wheel.
  • the carrying axles have idle wheels which may include an electronic speed control device to obtain an anti-braking device during braking.
  • the aforementioned distances a, d, n substantially verify the following relationship:
  • each end axle is added as an additional guide axle to the outside and the drawbar of said end axle is fixed to said guide axle perpendicular to the middle of the latter.
  • Figure 1 schematically illustrates the radial guide according to French Patent No. 2,526,387.
  • a curve shown schematically by the mean radius 21 of this curve two guided vehicles with steerable axles each comprising two axles 2 and connected together by two drawbars 4.
  • the distance between the articulation point 8 of the bar coupling 4 and the axis of rotation 12 of the axle 2 is designated by n;
  • d denotes the length of the drawbar of each vehicle;
  • a designates the distance separating the two axes of rotation 12 of the two axles of the same vehicle and
  • b designates the distance between the axis of rotation 12 of the axle and the contact point 11 of the drawbar 4 and the crossing.
  • Figure 2 illustrates the roll phenomenon. Because the body and the axles are not rigidly connected but by means of suspension elements 22, the body can perform rotational movements around a central longitudinal axis 23 called the roll axis; the angle of inclination of the body with respect to the axle 2 is called the roll angle (6).
  • a point M of the central longitudinal plane of the vehicle undergoes a horizontal displacement to come as far as possible in the position M ', this displacement being approximately equal to the product of the distance from the point M to the rolling axis 23 by the angle expressed in radian.
  • the point of attachment 8 of the drawbar on the body 1 therefore undergoes a horizontal displacement and it follows that the drawbar moves angularly in the horizontal plane, which results in the loss of the radial position of the axle 2 considered.
  • This angle of movement of the drawbar causes a rotation of the axle and this rotation can maintain the rolling movement, the body oscillating around its normal position.
  • this disruption of the radiality of the axles of a vehicle subjected to a rolling movement is avoided by the fact that the point of attachment 8 of the drawbar 4 on the body 1 is substantially arranged on the roll axis of the vehicle. In this way, during rolling movements, the attachment point remains stationary and the axle remains in the radial position.
  • This alignment of the point of attachment of the drawbar on the roll axis can be obtained by bringing said point of attachment to the level of the roll axis by modifying the structure of the hitch.
  • Another solution is to move the roll axis, that is to say to arrange the attachment points of the suspension elements 22 at a level such that the roll axis 23 passes substantially through the attachment point of the drawbar on the body.
  • FIG. 3 schematically represents two curved rails on which an axle 2 runs which then has an inner wheel 24 and an outer wheel 25.
  • the axle 2 is a conventional railway axle, that is to say that the two wheels 24 to 25 are integral with the axle 2, which means that they always rotate at the same speed.
  • E / R the outer wheel 25
  • E the track spacing
  • R the radius of the curve measured on the inner rail.
  • this slip can reach a value of 5%, which corresponds to a track gauge of 1.5 meters and a radius of curvature equal to 30 meters.
  • the sliding of the outer wheel causes a retarding effect T opposite to the direction of travel designated by arrow 26; this generates a torque which tends to oppose the radial positioning of the axle 2, this corresponding to a tendency to non-turn.
  • each driving axle has independent wheels in rotation and it is provided with a device making it possible to limit the slip between the two wheels.
  • a device making it possible to limit the slip between the two wheels. This can be achieved as shown in Figure 4 where the axle consists of two half-axles 27 and 28 which are connected to a differential device 29 whose possibility of sliding is limited, for example to 5%.
  • each non-driving axle consists of an axle 31 supporting idler wheels 32 and 33 each provided with a braking device 34 respectively 35; a schematic electronic device 36 controls the speed of rotation of each of the wheels 32 and 33 and acts on the braking device 34 and 35 to restore the equality of the resulting torques on each wheel, by braking the wheel in runaway in the in the case of a drive axle and by brake release of the two wheels in the case of a load-bearing axle (anti-skid device).
  • this vehicle length is generally predetermined and one cannot therefore act on this parameter to obtain radial guidance.
  • the parameter n that is to say the distance separating the axis of articulation of the axle from the axis of articulation of the drawbar is determined according to the following equation :
  • the invention makes it possible to obtain radial guidance of all the axles of a railway train independently of the roll movements and of the crossing of the curves by said train.
  • the invention is particularly advantageous in the field of railway vehicles traveling on tracks having curves with a small radius, which is the case in particular for urban metros.
