Definitions

  • the present specification relates to a patent of invention referring to a guiding system applicable to a four-wheel bogie with variable gap between them, the obvious purpose of which is to eliminate the inherent dynamic effects in this type of bogies equipped with independent wheels, so reducing the wear of the tread, specially that of the rim, the steering and conditioning of the brake for both gages being common, not requiring any other additional operation for being adapted to one and other gage.
  • This inventions applies to the railway industry.
  • One of the present solutions lies in a full replacement of the bogies, for which it is necessary to lift up the coach bodies, after uncoupling the damping or mechanical elements between body and bogie, as well as the brake system, the electric mass braids, and so on, which represents a series of laborious operations.
  • the guiding system could be also applicable to a bogie fitted with independent wheels having a fixed width, but not displaceable, to be able to run on different gages.
  • the guiding system applicable to a four-wheel bogie with variable gap between them, as proposed by the invention, constitutes per se an evident solution to the present problems in this matter, since the rolling assemblies are of the same type as those tested for many years in the trade service with the rollings utilized by the Talgo two-wheels daily running via the European networks, and on the two gages of the Spanish network, and it should be mentioned, in a specific manner, that the passing from one to other gage would be performed on a fixed installation, kown as changer, similar to those presently existing for effecting the gage change in the above-mentioned rollings.
  • both the steering and brake conditioning are common for both gages, not requiring any additional operation for adapting it to one and other gage, relying on the fact that any of the two guiding system improves the curve trajectory of thus type of bogie, so contributing to eliminate the dynamic effects which are inherent in this type of bogies equipped with independent wheels, and reducing the wear of the rolling tread, specially that of the rim.
  • the guiding system applicable to a four-wheel bogie with variable gap between them is constituted from a bogie essentially including a center frame, to which two identical frames are joined by means of a joint and rubber sandwiches, said two identical frames being the bearers of the rolling assemblies.
  • This second frame by turning around the joint vertical shaft, allows, as later described, the two mentioned rolling assemblies to be guided towards each of the identical frames, being joined by means of joints, both pair of arms, and each pair, jointly with the joint sleeve, defines a fork-shaped rigid assembly.
  • each of these forks there are housed the bearing boxes of each wheel and the elements allowing these rolling assemblies to be disposed on each of two track gages, and to block these in order to secure their total locking during the running.
  • Both guiding systems allow the two bogies of independent and displaceable wheels, with which a coach or wagon body of conventional type would be fitted, to be guided.
  • Each bogie is fitted with four rolling assemblies, and each of them is composed of a halfshaft, a wheel, the brake disks, intetral one other, and the bearing boxes mounted at one semishaft end.
  • the bearing boxes have, at their upper part, a cylindrical surface on which it is supported, in the normal position of running, the corresponding end of one of the fork arms.
  • an elastic sheet can be placed between the bearing box and the housing cradle. Said sheet is to be firmly adhered to one of these surfaces.
  • the vertical flat faces, one anterior and one posterior, are adjusted on the corresponding vertical flat faces of inserts.
  • the invention relies on lugs disposed on the anterior and posterior vertical faces of each bearing box and integral with it, constituting transverse fastening elements of the bearing boxes.
  • the latch stems integral with a bridge, are adjusted in a longitudinal direction through their external transverse faces between both vertical faces of the case, and they are transverselly held in correct position because they are adjusted between the longitudinal vertical faces of two inserts, integral with the oscillating arm case.
  • the latches can only be moved in a vertical sense, their displacement in any other direction being impeded by stiff stops.
  • the spring mechanism is eventually supplemented by a additional security retaining device.
  • the bridge of the latching device is so designed that, at its lower part, it can be inserted into a part having a "T" shape, belonging to the fixed installation, that is to say, the changer, which compels it to be vertically displaced, descending the latches, overcoming the force opposed by the springs, retainers and frictions.
  • This bridge is so designed that its inside adapts itself to the inclined planes existing on the unlatching guides of the fixed installation, so that they act on the center portion of the bridge.
  • One of the inserts presents a transverse guide having its upper face inclined, which constitutes a sliding surface for the bearing box during the transverse displacement of the rolling assembly.
  • the lower faces of lugs present this same inclination, and in normal operation, are separated from the upper faces of the guides and parallel thereto.
  • Sinterized metal material having a low sliding friction coefficient and a high compressive strength sliders, disposed on the inclined planes of the lugs, falicitate the rolling assembly displacement when transferrir the assemblies to be placed on each of the two gages.
  • the support carrying the brake cylinder and the steering device transmitting the motion to the brake connecting rods carrying the linings, would be fastened on the vertical transverse face of the lugs.

  • this system produces a guiding which is similar at the shafts of both bogies, and its operation is autonomous, and it does not need any conjuction of the vehicles which could be coupled to this coach.
  • taht is to say, when the guiding system is independent for each bogie, as schematically shown in Fig. 18, it should be pointed out that, in a similar manner to the other system, this Figure shows only the system corresponding to a side of each of the two bogies, existing, of course, another similar on the opposite side.

  • the balancer (44) inclines, since its joint, being integral with the center frame (1), displaces rearwards, that is to say, towards the inner side of the curve.
  • this balancer is effected by turning around its upper joint, since the bar (45) is integral with the support (46), which, in turn, is integrally joined to the frame of the - coach body.
  • this balancer (44) moves the bar (51), which pulls the lower end of the balancer (50), the upper end of which is also pulled by the bar (52), since the rear end thereof undergoes a displacement as a result of the bogie turning with regard to the body being integrally joined its joint fastening (53) to the main frame (1)
