Definitions
- the present invention relates to a railway vehicle with transverse movement of the bogie pivot of a wagon.
- a rail vehicle typically includes a chassis provided, at each of its ends, with a bogie which is mounted pivoting around an axis and ensures the self-alignment of the railway vehicle on the straight track, due to the interaction of the wheels with the rails.
- the invention more particularly aims to optimize the use of track gauge by rail vehicles.
- the term railway vehicle includes freight wagons, freight wagons road vehicles or containers, or even wagons of travelers, insofar as they are also subject to compliance with the templates.
- a track gauge is defined by an envelope line perpendicular to the axis of the railway track, the railway vehicle being required to remain entirely inside this template.
- the means of articulation described in this document are formed by two pairs of rods, arranged at the ends opposite two neighboring railway vehicles. These rods connect the side edges of a extending support plate from one wagon to another, a corresponding bogie being mounted pivoting at each end of this plate.
- EP-A-0 749 881 also provides for means for absorbing shock and traction occurring in a straight line between two railway vehicles neighbors. These means are constituted by spring systems integrated in the bogie support plate, so that allow some longitudinal travel between the two parts of this plate, each of which is integral with a corresponding railway vehicle.
- the present invention proposes to produce a vehicle rail to overcome all the disadvantages of the prior art mentioned above.
- FIG. 1 represents two railway vehicles 2, 2 ′, or wagons, provided with means according to the invention allowing the articulation of the bogie relative to the chassis. Only the articulation means with which vehicle 2 is fitted shown in this figure, but it should be understood that similar means equip the vehicle 2 ', as can be seen Figures 2 to 5.
- the bogie 4, running on rails 5, and the chassis 6 of the vehicle 2 are shown schematically.
- Two rods 8, 10, forming connecting rods, are articulated on the chassis of the vehicle 2 '.
- This joint is for example of the ball type, so that slight offsets between the chassis of vehicles 2 and 2 'are allowed.
- the rods 8, 10 are articulated, at their opposite end to vehicle 2 ', to levers designated respectively by the references 12 and 14. These are articulated to the rods by a first end 12A, 14A, and are adjacent one of the other at their second end 12B, 14B. These seconds ends affect a toothed angular sector profile and are likely to mesh with each other when subjected to longitudinal actions similarly direction, referring to the main axis of the vehicle.
- the articulation means equipping the vehicle 2 include also a support member 16 of the bogie 4, the function will be explained in the following.
- This organ is triangular shape and is free to rotate relative to an axis 18 integral with the chassis 6 of the rail vehicle 2.
- the bogie 4 is articulated relative to this support member 16, along an axis 19 located near a vertex 16A of this member 16.
- the member 16 is further articulated to the lever 12, 14 in one midpoint 12C, 14C of these. This link is ensured by corresponding axes 20, 22, called medians, which extend between the midpoints 12C, 14C mentioned above and the vicinity of the vertices 16B, 16C of the support member.
- Figure 2 shows the two rail vehicles 2, 2 ' in normal running in a straight line.
- bogie 4 pivot axis 19 is located on the right (D) which materializes the median axis of the rail vehicles 2, 2 '.
- Rods 8 and 10 are arranged substantially parallel to this straight line D, while the levers 12, 14 him are perpendicular, their respective ends meeting at the middle of the toothed sectors 12B, 14B.
- Figure 3 shows the two vehicles 2, 2 'of the figure 2, subjected to a traction relative to the position materialized in this figure 2.
- Such traction may for example be due to starting, to an acceleration of the train or to a hill climb from this latest.
- This traction causes a distance between the wagons, which is absorbed mechanically by a hook traction not shown, of known type, and which contributes to exert tensile forces F and F 'on the rods 8, 10.
- These tensile forces which are of substantially equal intensities and are exercised in the same longitudinal direction, have the effect to bring the end 12A, 14A of the levers closer to the vehicle 2 ', so that these levers 12, 14 pivot around their respective median axis 20, 22.
- Their toothed ends 12B, 14B move, by mutual engagement, according to the arrows respective G, G '.
- These toothed sectors are then in contact through their longitudinal ends closest to axis 19.
- FIG. 4 represents the vehicles 2, 2 ′ of FIG. 2, close to each other in relation to the walking position normal illustrated in this figure 2. Such an approximation can be due to braking, deceleration of the train or when the latter moves in a drop.
- This rimpedement which is absorbed mechanically by pads, not shown, of known type, contributes to exerting compression forces H, H 'on the rods 8, 10.
- These forces which are of substantially equal intensities and are exercised according to the same direction, tend to rotate the levers 12, 14 around of their median axes 20, 22, which has the effect of making pivot the ends 12B, 14B of these levers according to the respective arrows I, I '.
- These toothed sectors 12B, 14B mesh with each other and are in mutual contact by through their respective longitudinal ends, opposite the axis 19 of pivoting of the bogie 4.
- Figure 5 illustrates the two vehicles 2, 2 'registered in a curve.
- the rod 8 is subjected to a tensile force exerted according to arrow J while the rod 10 undergoes a materialized compression force by arrow J '.
- These forces which are intensities of little nearly equal, are exercised in different directions. They have for the effect of inducing stresses on the toothed ends 12B, 14B of the levers 12, 14, indicated by the arrows H and H '.
- levers 12, 14 are secured to the support member 16, via the median axes 20, 22, the overall pivoting of these levers causes the rotation of the member 16 around the pivot axis 19 of the bogie causing the D axis to move outward of the curve.
- the straight line connecting axes 18 and 19 is inclined of the same angle ⁇ as that relating to the pivoting of the levers 12, 14.
- the articulation means of the bogie undergo relative displacements similar to those described with reference in FIGS. 3 and 4, the inclination according to the angle ⁇ , due to the passage in curve, being preserved.
- FIG. 6 represents the means of articulation of a bogie of a railway vehicle according to a second mode of realization of the invention.
- the articulation means of the bogie 104 comprise two rods 108, 110 articulated at the end of the vehicle 102 ', adjacent to the vehicle 102. It should be noted that the rods 108, 110 have a length significantly shorter than that rods 8, 10 described with reference to the preceding figures. At these rods 108, 110 are articulated two levers 112, 114, at level of a first end 112A, 114A of the latter. These levers 112, 114 are further connected to each other at near their second end 112B, 114B, via of a part 116 forming a link.
- the articulation means of the bogie 104 include also a spreader 118, of elongated shape and free of pivot relative to the chassis 106, along an axis 120 passing through the middle of this spreader 118.
- the latter is also articulated at its two ends with two levers 112, 114, around axes 122, 124 passing through a middle zone 112C, 114C of these levers.
- These axes 122, 124 will be referred to in what follows median axes.
- a connecting member 126 is provided at a distance from the lifter 118, opposite the neighboring vehicle 102 '.
- This body 126 is free to pivot relative to chassis 106, about an axis 128.
- the bogie 104 is itself articulated with respect to this connecting member 126, around an axis 130. The latter is spaced from the axis 128, towards the vehicle neighboring railway 102 '.
- the support member 126 and the lifter 118 are further connected to each other by means of two bars 132, 134. These are articulated, at a first end, at the axes 122, 124 of articulation of levers with respect to the lifter and, at their other end, on either side of axis 128.
- the lifter is said to be synchronized in rotation with the support member, since the pivoting of the spreader around its axis 120 causes pivoting, according to the same direction, of the member 126 around its axis 128.
- the rods 108, 110 extend substantially parallel to the right D 'which materializes the median axis of this vehicle 102.
- the spreader 118 extends perpendicular to this straight line D ', and the pivot axis 130 of the bogie 104 relative to the chassis 106 is located on this straight line D '.
- Figure 8 illustrates the approximation of the two vehicles adjacent 102, 102 ', analogously to what has been described about the previous embodiment with reference to the Figure 4.
- the rods 108, 110 are subjected, under the effect of a such approximation, at compression forces represented by arrows F, F 'of substantially identical intensities and exercising in the same sense. This helps to rotate each of the levers 112, 114 around its respective median axis 122, 124.
- the ends 112B, 114B of the levers 112, 114 are then constraints to move according to arrows G, G ', on a circle whose center corresponds to the trace of the median axes 122, 124 on the levers 112, 114.
- the link 116, articulated to the two levers 112, 114, is therefore required to follow the movement of the ends 112B, 114B of these levers. Given that the distance between these ends 112B, 114B is not constant, it is necessary to provide light functional clearances at the articulation between the link and these levers 112, 114.
- FIG. 9 represents a phase of traction between the two wagons 102, 102 'from the position illustrated in the figure 7.
- Two tensile forces represented by the arrows I and I ', are exerted on the rods 108, 110. These forces are substantially identical in terms of their intensity and are exerted in the same sense. They help to rotate levers 112, 114 around their respective median axes 122, 124, according to the arrows J, J '.
- the link 116 is bound to follow the movement described by the extremities 112B, 114B levers 112, 114.
- This link 116 pivots so slightly around its midpoint 116A, according to the arrow K.
- FIG. 10 represents the railway vehicles 102, 102 'inscribed in a curve.
- the rods 108, 110 are subjected to respective forces of compression L and traction L ', of intensities substantially identical but exercised in two opposite directions.
- the levers 112, 114 are in theory free to pivot around the median axis 122, 124, the presence of these forces L, The theoretically tends to move the ends 112B, 114B of the levers according to respective arrows N, N '.
- N and N ' are representative of substantially identical forces and acting in opposite directions, so that the rotation of the levers 112, 114 around the median axes 122, 124 is prevented due to the presence of the link 116.
- the spreader 118 which is articulated at its two ends to levers 112, 114 is also required to pivot around its axis 120 connecting it to the chassis 106.
- the pivoting of the spreader 118 induces respective actions on bars 132, 134, materialized by arrows O and O '. These actions, which are practiced in two directions opposite, are at the origin of a couple tending to rotate the support member 126 around the pivot axis 130 of the bogie 104, according to arrow P. This contributes to offset the axis median longitudinal of the vehicle, represented by the straight line D ', towards the outside of the curve with respect to the axis 130.
- the invention makes it possible to achieve the objectives previously mentioned. Indeed, the means of articulation of the bogie that it implements, while reliably ensuring the offset of the vehicle axis towards the outside of a curve, guarantee satisfactory shock absorption and traction between two neighboring vehicles, that these the latter are found in a curve or in a straight line.
