Definitions

  • the present specification relates to a Patent of Invention concerning bogies for railway vehicles with variable gap between wheels, the evident object of which is to allow a variable gap between the bogie wheels, the bogie being equiped with independent wheels, and checking that each rolling assembly is composed of a wheel fixed to an independent axle provided with bearings located at both ends, relying on the possibility of displacing each complete rolling assembly, the arrangement of the bearing boxes changing only and exclusively in relation to the bogie.
  • This invention applies to the industry engaged in the construction of railway vehicles, and its general application being also to the railway industry.
  • One of the present solutions is to replace the whole bogies, for which it is totally necessary to raise the coach bodies, - disassembling previously the elements forming the brakes, as well as the electric mass braids, etc., these operations representing a substantial amount of lost time and which are considered as extremely laborious.
  • the main difficulty impeding to obtain an appropiate mechanism of this type is, mainly, the fastening of the wheel to the axle body so that it can give the same guarantees of safety, toughness, etc., etc., as the wheels fitted under pressure to an axle according to the typical procedure.
  • each rolling assembly is formed by a wheel fixed to an independent axle fitted with bearings at both ends thereof, relying on the possibility of displacing each complete rolling assembly, the arrangement of the bearing boxes changing only functionally with regard the bogie.
  • the bogies for railway vehicles with variable gap between wheels will allow a quick change of the gap between wheels when passing through a fixed installation carrying out the necessary operations for running via two networks having a different gauge.
  • the invention has the following advantages incorporated in - this new type of bogies.
  • the bogie which is the object of this invention is essentially composed of a center frame, to which four oscillating arms are united by means of corresponding joints , at one of which ends bearing boxes for each of the rolling assemblies are housed.
  • Said rolling assemblies can move transversely, the wheels - being located in each of two positions corresponding to both - gauges.
  • each arm rests on the relative helical spring, the lower end of which rests on the center frame bottom.
  • the bogie is equipped with another secondary suspension.
  • this type of bogie would be equipped with a guiding system, or the system could be adapted to an articulated bogie.
  • Each bogie is fitted with four rolling assemblies, each of which is composed of a semiaxle, wheel, brake discs, all them common each other, and the bearing boxes mounted at the ends of the semiaxle.
  • the bearing boxes have, at their upper side, a cylindrical surface on which the relative end of the oscillating arm of the bogie is resting, in the normal running position.
  • a resilient sheet can be interposed between the bearing box and the housing cradle, and said sheet must be securely fastened to one of these surfaces.
  • the vertical position bewteen bearing boxes and oscillating arm is, in this way, defined.
  • Said surface being cylindrical, in a longitudinal sense, the axis of the bearing box is automatically centered on its theorical position.
  • the vertical flat faces one at front and one at rear, are fitted on the relative vertical flat faces of inserts.
  • each of said lugs wherein this contact is effected, are separated each other a distance which is similar to the half difference of gauges decreased of the latch thickness.
  • the latches which are common with a bridge, are adjusted in longitudinal sense by their outer transverse faces between the two vertical faces of the oscillating arm case, their correct position being held because the latches are adjusted between the vertical longitudinal faces of the inserts which are common in the oscillating arm case.
  • the spring mechanism is complemented by an additional safety retaining device.
  • the bridge of the latching device is so designed that a "T" shaped part belonging to the fixed installation can be introduced into the lower part of said bridge.
  • This "T” shaped part forces it to be vertically displaced, causing the latches to descend, overcoming the force opposed by springs, retainers and frictions.
  • Said bridge is designed in such a way that its inside adapts itself to the inclined planes existing on the dislatching guides of the fixed installation, so that they act on the central zone of the bridge.
  • the bridge has vertical transverse faces on which the faces of the bearing boxes are adjusted in a longitudinal sense.
  • a part presents a transverse guide which has an upper face inclined constituting the sliding surface of the bearing box during the transverse displacement of the rolling assembly.
  • the lower faces of the lugs have this same inclination and in normal running they are separated from the upper faces of the guides and parallel thereto.
  • Figure 1 shows a side elevational view of the bogie for railway vehicles with variable gap between wheels which is the object of the invention.
  • Figure 2 shows a plan view of the object illustrated in Figure 1.
  • Figure 3 shows a perspective view of one of four rolling - assemblies incorporated in the bogie which is the object of the invention
  • Figure 4 shows a side elevational view of the cylindrical surface on which the relative end of the oscillating arm of the bogie is resting in a normal running position.
  • Figure 5 shows a plan view of the object illustrated in Figure 4.
  • Figure 6 shows a sectional detail along A-B of the object illustrated in Figures 4 and 5.
  • Figure 7 shows a perspective view of the vertical flat faces, one in front and one in rear, which are adjusted on the relative vertical flat faces of the inserts.
  • Figure 8 shows a sectional view of the object illustrated in Figure 7, corresponding to positioning and blocking elements of the bearing box in the oscillating arm case of suspension.
  • Figure 9 shows a detail of the object illustrated in Figures 7 and 8, along the line C-D.
  • Figure 10 shows a front elevational view duly sectioned from the rolling assembly and the housing cases of bearings.
  • Figure 11 shows a perspective view of the locking latch assembly.
  • Figure 12 shows a sectional view of the object illustrated in Figure 11.
  • Figure 13 shows a plan view of the fixed installation for - changing the gauges.
  • Figure 14 shows, finally, a sectional view of the centering and sliding runners resting on the sliding rail.
  • the bogie for railway vehicles with variable gap between wheels which is the object of this invention, configurates starting from a center frame 1, to which four oscillating arms are united by means of relative joints 2, at one of which ends the bearing boxes for each of the rolling assemblies 3 are housed.
  • These rolling assemblies 3 can transversely move, the wheels being placed in each of two position corresponding to both gauges.
  • each of the arms is resting on the relative helical spring 4, the lower end of which is resting on the center frame bottom 1.
  • each of these assemblies constitutes the suspension of the corresponding rolling assembly, it being specifically understood that, apart from this primary suspension, the bogie will be equipped with another secondary suspension.
  • this type of bogie will be equipped with a guiding system, or by means of a system which could be adapted to an articulated bogie.
  • Each bogie is fitted with four rolling assemblies as that shown in Figure 3, each of which is composed of a semiaxle 6, a wheel 7, brake discs 8, which are common each other, and the bearing - boxes 9 which are mounted at the semiaxle ends.
  • the bearing boxes 9, which can be seen in Figure 3, have, at their upper part, a cylindrical surface 10 on which there is resting, in the normal running position, the relative oscillating arm end of the bogie, such as it is shown at the sectioal view of Figure 4.
  • a resilient sheet can be interposed between the bearing box and the housing cradle, this sheet must be firmly adhered to one of these surfaces.
  • Said surface being cylindrical, in a longitudinal sense, the axis of the bearing box is automatically centered in its theorical position.
  • the vertical flat faces 11, one at front and one at rear, are fitted on the relative vertical flat faces of inserts 12 and 13.
  • Lugs 14 located on the front and rear vertical faces of each bearing boxes, and which are common to it, constitute the transverse fastening elements of the bearing boxes.
  • each of said lugs 12 wherein this contact is made, are separated each other a distance which is similar to the half difference of gauges decreased of the latch thickness 14.
  • the latches 16, which are common with a bridge 17, are adjusted in longitudinal sense by their outer transverse faces between the two vertical faces of the oscillating arm case, their correct position being held because the latches are adjusted between the vertical longitudinal faces of the inserts 12 and 13, which are common with the oscillating arm case.
  • the latches only can be displaced in vertical sense, their displacement being impeded in any other direction by means of rigid stops.
  • the spring mechanism 18 is complemented with an additional safety retaining device 19.
  • the bridge 17 of the latching device is so designed that a "T"-shaped part belonging to the fixed installation can be introduced into the lower part of said bridge,
  • the "T” shaped part forces it to be vertically displaced, causing the latches to - descend, overcoming the force opposed by the springs, retainers and frictions.
  • Said bridge is designed in such a way that its inside adapts itself to the inclined planes existing on the dislatching guides of the fixed installation, so that they act on the central zone of the bridge.
  • the inserts 12 and 13 which are mounted in common on the vertical faces of the oscillating arm case, in addition to act as a transverse stop for the latches, have vertical transverse faces on which the faces 11 of the bearing boxes are adjusted in longitudinal sense.
  • the part 13 has, moreover, a transverse guide 20, having its upper face inclined, which constitutes the sliding surface of - the relative bearing box during the transverse displacement of the rolling assembly.
  • the lower faces 21 of the lugs 14 have this same inclination and in normal running they are separated from the upper faces of guides 20 and parallel to it.
  • the change of gap between wheels is to be always made with the aid of a fixed installation located in the changing station.
  • This change is made consecutively in each of the bogies when these pass at a reduced speed, which can attain up to a maximum of 20 km/h, through said fixed installation.
  • Figure 13 shows schematically the several elemnts forming part of the installation, which are as follows:
  • the end of the rails of the larger gauge is referenced 23, - while the end of the rails of the smaller gauge is referenced 24.
  • the sliding and centering guide rails are referenced 25; the unlocking and locking of latches are referenced 26, and the guides for moving the rolling assemblies, with regard to the resilient parts, are referenced 27, and the stiff parts, 28.
  • the runner 30.B leans on its support 30.A - through a spherical articulated joint.
  • the supporting runners are made of a plastic material and are lubricated with water, so obtaining a very low friction coefficient when they slide on the sliding rail.
  • the lubrication with water has a considerable advantage over other lubricants, since it does not cause, in any case, adherences or contamination.
  • the section of the upper part of these guides adopts a "T" configuration, which allows the latch bridges to enter it, and owing to the configuration of its vertical profile 31, the latches descend and are held unlocked in the central part of guides, where its profile is fully horizontal.
  • the friction parts of the latch bridges 32 are made also of a plastic material, the lubrication is effected also with water in order to obtain the above-mentioned advantages.
  • the resilient portion of the guides for displacing the rolling assemblies corresponding to this gauge 27 contact the inner face of wheels.
  • the rolling assemblies descend lightly and do not support the upper part 10 of the bearing boxes on the seats of the oscillating arm cases, and then the inclined faces 21 of the mentioned lugs 14 lean on the inclined face of guide 20.
  • the wheels lose contact with the resilient part of the moving guides on the side through which it has been entered, and, next, they contact the stiff part of the moving guides on the opposite side, that is to say, where the lesser gauge is located.
  • the pressure exerted by the resilient part of the moving guides makes easy to lock the latches.
  • the rolling assemblies are locked in a position corresponding to the track having the smaller gauge.
