Definitions

  • the present invention is related to railway vehicle buffers, of the type comprising a buffer casting intended to be fixed to one headstock of the vehicle and a hollow buffer stem slidably supported by the buffer casting and carrying a buffer end plate.
  • the buffer end plate is traditionally fixed rigidly to the buffer hollow stem and projects from the vehicle headstock permanently, i.e. even in the case the vehicle is not to be coupled with other railway carriages and the presence of the buffer is not strictly necessary.
  • a solution for overcoming the above drawback consists in connecting the buffer end plate to the buffer stem detachably, so as to allow removal thereof whenever its presence is not necessary. Disassembly must be carried out manually and therefore, considering the weight and size of the buffer plate, this operation is uncomfortable and fatiguing, requires a long working time and involves the need of providing for a suitable store onboard the vehicle for containing the removed buffer plates.
  • Another known solution particularly suitable for the vehicle front headstock, consists of employing an auxiliary fairing releasably applied so as to cover the buffers. Even this solution is however unpractical and has the same drawbacks, as far as the applications and removal operations of the auxiliary fairing are concerned, previously mentioned in connection with the detachable buffer plates.
  • the object of the present invention is to provide a buffer of the type defined at the beginning, which is adapted to take, in a constructively simple and functional way, starting from the normal working position, a rest position in which it does not negatively affect the aerodynamic characteristics of the vehicle on which it is applied, in the same time safeguarding its elastic absorbtion effectiveness in the case of accidental collision.
  • this object is achieved by virtue of a railway vehicle buffer of the above-specified type, the main feature of which resides in that the buffer end plate is rotatably connected to the buffer stem so as to be displacable between an extended working position and a retracted rest position.
  • connection between the buffer plate and the buffer stem comprises a pair of studs of which one defines the axis of rotation of the buffer plate between the said extended and retracted position, and the other is constituted by a releasable latch.
  • the axis of rotation of the buffer plate is vertical, whereby in the retracted position the buffer end plate is positioned aside the buffer casting-stem assembly.
  • Displacement of the buffer end plate from the extended working position to the retracted rest position, and viceversa, can be comfortably operated manually, or alternatively a suitable servomechanism can be provided.
  • the invention is further related to a high-speed railway vehicle provided with a pair of buffers according to the above, attached in spaced correspondence to at least one headstock thereof, which may also be provided with an aerodynamic fairing.
  • the vehicle according to the invention is mainly characterized in that the said fairing is provided, in frontal correspondence of each buffer, with movable sections adapted to be removed so as to allow projection of the buffer plate outwardly in the extended working position, and to be re-applied when the buffer plate is returned in the retracted position within the fairing.
  • reference T designates the front headstock of a high-speed railway vehicle, provided with an aerodynamic fairing C with two openings A formed in an inferior portion, through each of which a buffer end plate of a respective buffer 2 projects outwardly.
  • each buffer 2 comprises, in a way generally known per se, a buffer casting 3 provided with a connecting flange 4 for the rigid fixing to the structure of the headstock T, and a hollow buffer stem 5 carrying the buffer end plate 1 and slidably supported by the buffer casting 3.
  • Axial backing of the buffer stem 5 (and thus of the buffer end plate 1) relative to the buffer casting 3 enables, as is known, absorbtion of frontal impacts possibly transmitted during travelling by a railway carriage coupled ahead of the headstock T, or during manoeuvres of the vehicle.
  • a conventional elastic dissipator system is interposed between the buffer stem 5 and the buffer casting 3, within the latter.
  • the buffer end plate 1 is not connected rigidly to the free end of the buffer stem 5, but rotatably between an extended working position, shown in figure 1 and in continuous lines in figure 2, and a retracted or folded rest position, shown in dotted lines in figure 2 and in figure 4.
  • the structure of the buffer end plate 1 incorporates internally an upper plate 6 and a lower plate 7 between which a support body 8, mounted in the teminal portion 9 of the buffer stem 5, is inserted.
  • connection between the two plates 6, 7 of the buffer plate 1 and the support body 8 of the buffer stem 5 is performed, in the case of the shown example, by means of a pair of verticals studs 10, 11 placed side by side and inserted through corresponding holes 6a, 7a, 8a and 6b, 7b and 8b of the plates 6, 7 and of the body 8, respectively.
  • the stud 10 is fixed, and the axis X thereof defines the pivot axis of the buffer plate 1 between the extended and the retracted positions.
  • the stud 11 defines on the other hand a relasable latch, and to this purpose it is provided at its upper end with a grip eye 12 and at its lower end with a radial stop pin 13, which can be pulled out in order to allow extraction upwardly of said stud 11.
  • the buffer plate 1 In the extended working position the buffer plate 1 is placed on the prolongation of the buffer stem 5, with the stud 11 inserted through the holes 6b, 7b of the two plates 6 and through the hole 8b of the support body 8, and is projecting in front of the fairing C of the headstock T through the corresponding opening A. In such a position the buffer plate is able to receive and transmit to the buffer 2 any possible front impact.
  • the buffer plate 1 In the retracted position the buffer plate 1 is fully housed within the fairing C and the relative opening A can be advantegeously closed by applying a movable section S which completes the aerodynamic profile of the fairing C and is detachably secured thereto by any suitable means, such as screw locking members or the like.
  • the buffer 2 is in any case able to protect the railway vehicle from possible accidental collisions, through the push applied through the fairing C to the end 9 of the buffer stem 5.
  • the axis of rotation X of the buffer plate 1 could be placed differently from the vertical direction, i.e. could be oriented horizontally or even obliquely.
