Definitions

  • the invention relates to a pulling device for rail vehicles, consisting essentially of a support plate which can be connected to the vehicle, a pull rod penetrating the support plate and a spring, preferably a friction spring, the pull rod having a coupling body at its front end and a coupling element at its rear end has cooperating with the spring nut and the outer surface of the spring is surrounded by a housing.
  • Towing devices with the aforementioned features are known from the applicant's publication "Messages from the Design Office 1/78".
  • the support plate and the housing are connected to one another via a screw arrangement.
  • the friction spring located inside the housing bears against the support plate and receives its pretension via the tension element through the nut held on the tension rod.
  • the vehicle-side assembly of such a traction device takes place as a structural unit by attaching the support plate to the carrier structure of the vehicle.
  • UIC leaflet 520 which also belongs to the state of the art, the support plate and the tie rod are standardized components, the choice of the spring being free is provided.
  • the rubber springs commonly used in practice in connection with these standardized components have a comparatively short lifespan and are not sufficient in terms of their working capacity due to the increased vehicle weights.
  • the invention has for its object to provide a traction device of the generic type so that the spring and housing can be assembled as a compact, ready-to-install structure by simply sliding onto the pull rod with the support plate designed, for example, according to UIC Leaflet 520.
  • the spring is supported on the one hand on the inner surface of a front base plate which can be placed against the support plate and on the other hand - in particular with a nut which has not yet been mounted - via the tension element on an inwardly directed collar of the housing connected to the base plate with tensile strength under pretension is.
  • the spring and the housing are advantageously combined to form a ready-to-install structure containing the pretension for the spring.
  • the spring capsule of this type can be used freely, that is to say it can be connected downstream of all the support plates which are customary in practice, for example according to UIC leaflet 520 or a vehicle-side carrier.
  • the spring capsule is simply pushed onto the pull rod and placed against the support plate, with the subsequent screwing and tightening of the nut only by a fraction of a turn, the bias of the spring on the base plate on the support plate.
  • This assembly of the support plate and spring capsule is possible in the original equipment and in replacement cases, for example the rubber spring is omitted, in a favorable manner with the support plate connected in the vehicle; the spring capsule, which remains under tension, can also be removed while leaving the support plate.
  • the spring capsule remains unchanged in its preload even when the pull rod can be replaced quickly, e.g. in the event of greater wear.
  • a particularly efficient manufacturing technology, absorbing the biasing force of the spring and otherwise absolutely tight connection between the base plate and the housing is achieved according to one embodiment of the invention in that the base plate and the housing are connected to one another by welding.
  • a next embodiment of the invention is that the base plate receives the pull rod in the sense of a guide.
  • This guide facilitates the assembly of the drawbar and spring capsule and ensures the function of the drawbar in operation even when the support plate has no or insufficient guidance for the drawbar.
  • the base plate has a tubular extension and forms a guide for the tension element via this extension.
  • this guide the tubular extension of the base plate with a corresponding length can directly grasp the outer circumferential surface of the tension element.
  • Another design option for the guide consists in a telescopic assembly of the tubular extension of the base plate and an extension of the tension element arranged in or on this extension.
  • the horizontal base plate has a width that is equal to the corresponding dimension of the installation space for the traction device and counteracts it via its vertical side surfaces which rests on the surfaces delimiting the installation space.
  • the base plate is provided with a web resting against a horizontal flange of the support plate.
  • the base plate has a vertically arranged groove on its outer surface facing the support plate.
  • This groove advantageously brings about a direct removal of moisture, which possibly occurs at the point of passage of the pull rod through the support plate or between this plate and the base plate.
  • a supplementary embodiment of the invention is that the tension element and the housing in the rear area of the tension device are designed in the manner of a guide.
  • the pulling devices according to FIGS. 1 to 3 contain a spring 1 designed as a friction spring with interlocking conical rings.
  • This spring 1 is under Tension is supported via its front end against the inner surface 3a of a base plate 3 and, if the nut 4 has not yet been mounted, via its rear end by arranging a tension element 5 against an inwardly directed collar 6a of a housing 6 which surrounds the outer surface of the spring 1.
  • the base plate 3 and the housing 6 are connected to one another in a tensile manner, in the present examples by welding.
  • the respective base plate 3 bears against a support plate 2 which can be screwed onto the vehicle via a horizontal flange 2a.
  • the support plate 2 is penetrated by a pull rod 7, which has a coupling body 7a at the front, for example the fork head shown for articulated accommodation of a pulling hook, and the nut 4 at the rear.
  • the nut 4 works via the tension element 5 with the spring 1, the pretensioning of which is only effective by tightening the nut 4 by a fraction of a turn via the base plate 3 on the support plate 2; between the tension element 5 and the collar 6a of the housing 6 can then - see Fig. 1, upper half - there is a small distance.
  • the base plates 3 are each provided with a tubular extension 3b, which is arranged near the pull rod 7 in FIG. 1 and away from the pull rod 7 according to FIGS. 2 and 3.
  • This element 5 is stabilized by the telescopic interaction of the tubular extension 3b with an extension 5a of the tension element 5 (FIGS. 1 and 2) or the outer peripheral surface of the tension element 5 (in FIG. 3).
  • the respective base plate 3 receives the pull rod 7 in the sense of a guide.
  • the tubular extension 3b also serves this purpose in the design according to FIG. 1; 2 and 3, the base plates 3 have a corresponding Er Elongation in the longitudinal direction. 2 and 3, the traction element 5 and the housing 6, as can be seen, are designed in the manner of a guide.
  • a slide bushing 9 is arranged within each of the above-mentioned guides and, in addition to the smooth interaction of these guides, ensures that the spring 1 is shielded reliably against dust and moisture.
  • This shielding can be additionally secured by a bellows 10 shown in FIG. 1, which is fastened to the tubular extension 3b of the base plate 3 and to the tension element 5.
  • a bellows 10 shown in FIG. 1 which is fastened to the tubular extension 3b of the base plate 3 and to the tension element 5.
  • an annular groove 3g also acts in the tubular extension 3b of the base plate 3, which, if appropriate, picks up contaminations on the sliding bushing 9 scraped off by the extension 5a of the tension element 5.
  • the sliding bush 9 between the base plate 3 and the pull rod 7 is largely kept free of moisture in all cases by a groove 3f in the outer surface 3e of the base plate 3, this groove 3f according to FIGS. 2 and 3 via bores 3h with the space between the pull rod 7 and the tubular extension 3b with respect to drainage.
  • the base plate 3 of the traction device according to FIG. 1 has - see FIG. 4 - a width that is equal to the corresponding dimension of the installation space in the horizontal and bears against its surfaces 8c that laterally delimit the installation space via its vertical side surfaces 3c.
  • the base plate 3 of the pulling devices shown in FIGS. 2 and 3 can be designed accordingly. If such a widening of the base plate 3 is dispensed with, then the introduction of transverse force takes place via the large-area bearing of the base plate 3 on the support plate 2, which spring preload is applied.
  • a web 3d is shown on the base plate 3 with dash-dotted lines, the web 3d resting against the horizontal flange 2a of the support plate 2.
  • This support facilitates the attachment of the spring capsule and acts as an anti-rotation device.
  • the four bores in the base plate 3, also shown in dash-dotted lines in FIG. 4, are provided for the case in which a screw connection between the base plate 3 and the support plate 2 is desired.
  • FIGS. 1 and 2 An assembly opening in the bottom of the housing 6 for the nut 4 arranged within the tension element 5 is, according to FIGS. 1 and 2, tightly covered by a closure cap 11 with a tensioning strap 11a placed over the bottom of the housing. 3, the correspondingly designed collar 6a of the housing 6 receives a cover 6b which also tightly closes the housing 6.
