Definitions

  • the present invention relates to railway track apparatus, and more particularly to a device for elastic fastening of track apparatus rails, in particular a counter-needle routing rail positioned in a sliding bushing.
  • Devices of this type are known, for example, from DE-A-21 53 534, DE-A-32 30 612, EP-A-0 275 604 and DE-A-24 09 138.
  • the switches of the railway networks are usually constituted, for each line of rails, by a fixed counter-needle rail with which cooperates a movable needle rail moving transversely to the axis of the track, and can be, at will, applied or separated from the adjacent counter-needle rail.
  • a switch is said to "high needle” in the case where the needle rail has the same height as the counter-needle rail, and “needle low” in the case where the needle rail is of less height than the rail against -needle.
  • the needle rail rests by its mobile part on sliding bearings.
  • a particular sliding bearing which comprises a recess allowing the insertion of a substantially U-shaped elastic fastener, the head of this fastener resting on the inner shoe of the counter-needle rail.
  • the support force on the pad which is of the order of 1200daN, is obtained by the tensioning of this fastener by provision of the two ends of its branches in two raised housing provided for this purpose and located at the end of the pad.
  • the elastic fastener is a sensitive part of the device and must thus be positioned accurately and without suffering any damage during its introduction, to avoid premature degradation, which would lead to an increased risk of breakage that seriously jeopardizes safety.
  • the assembly is carried out, in principle, in five steps, namely the insertion of the fastener in the recess, the setting up a branch in intermediate position, its displacement to the final position, followed by the establishment of the other branch in the intermediate position and its movement to the final position.
  • the longitudinal positioning of the fastener in the recess remains rather random, and can not be guaranteed repeatedly and rigorously, because it is mounted on a chair and such a fitting must be performed with a game.
  • the application effort becomes variable and is therefore not known and can not be guaranteed.
  • the object of the present invention is to overcome these drawbacks by proposing a device for elastic fastening of rails of track apparatus, in particular a counter-needle routing rod positioned in a sliding bushing allowing precise positioning of the latter. and avoiding any risk of rapid wear.
  • the device for the resilient attachment of a fixed counter-needle rail of points cooperating with a movable needle rail movable transversely to the track comprising a bearing pad for the counter-needle rail and sliding pad for the rail needle, the counter-needle rail being, in the position of use, maintained, on the one hand, on the outer side of the track by a fastening means and, on the other hand, on the inside of the track by a fastener substantially U-shaped elastic, said elastic fastener being disposed in a recess of the bearing, the respective ends of the branches of the penetrating fastener, in tensioning position of said elastic fastener, via a stop intended for ensuring the force of plating the counter-needle rail on the bearing, in raised housing provided for this purpose in said bearing, is characterized in that the elastic fastener comprises, close to the end of each leg of the U forming it, a protruding element, in the form of a bump or lug in one piece with
  • Figures 1 and 2 of the accompanying drawings show a device for the elastic fixation of a fixed counter-needle rail 1 of points cooperating with a movable needle-rail able to move transversely to the track, the device comprising a bearing pad 2 forming a support for the counter-needle rail 1 and a sliding pad 2 for the needle rail, the counter-needle rail 1 being, in the position of use, maintained, on the one hand, on the outer side of the track by a fixing means and, on the other hand, on the inner side of the track by a resilient fastener 3 substantially U-shaped, said elastic fastener 3 being disposed in a recess 4 of the bearing 2, the respective ends of the branches 5 of the penetrating fastener, in the tensioning position of said elastic fastener 3 , via a stop 6 intended to ensure the plating force of the counter-needle rail 1 on the pad 2, in raised housing 7 provided for this purpose in said pad 2.
  • the resilient clip 3 comprises, near the end of each leg 5 of the U forming it, a protruding element 8, shaped like a hump or one-piece lug with said end, said projecting elements being pressed against an upper flange 4 'of the recess 4 of the bearing 2, in a position of maximum depression of the fastener in said recess.
  • the projecting elements 8 of the elastic fastener 3, in the form of bumps or lugs, are made by forging.
  • projecting elements 8 provided near the end of each branch 5 of the elastic fastener 3, are designed to ensure the insertion of the elastic fastener 3 to its normal longitudinal position in the recess 4 of the pad 2, with obtaining a perfect longitudinal positioning of said elastic fastener 3.
