Definitions

  • the invention relates to a lifting cylinder for magnetic rail brakes, with which the magnetic brake is lowered or raised.
  • the present invention is therefore based on the object of avoiding the disadvantages of the known suspensions or actuating cylinders, but not having to disclose their advantage.
  • a damping ring is arranged between the cylinder cover and the mounting flange of the piston rod, which has a greater or the same damping capacity than the bearing ring used and the bearing ring or rings have the same or greater hardness than the damping ring, wherein the damping ring consists of an elastic or elastomeric material.
  • the damping ring is advantageously equipped with a square cross section.
  • the bearing rings can suitably consist of individual segments and be preloaded.
  • a divided or undivided support made of metal, plastic or the like is preferably provided on the side of the damping ring facing the cylinder cover and / or the fastening flange. attached, for example vulcanized.
  • the advantage of the invention is that the vibration damping is kept completely away from the suspension of the actuating cylinder on the vehicle and can be adapted to practical requirements by changing the material properties of the damping ring.
  • the cylinder cover 12 is arranged at the lower end of the actuating cylinder or lifting cylinder 11, through which the piston rod 13 emerges.
  • the mounting flange 14 is arranged, which, with its annular part 14A, lies between two rubber rings 15 and 16. These rubber rings 15 and 16 form the bearing for the annular part 14A of the mounting flange 14.
  • the two bearing rings 15 and 16 are brought to the desired preload with the nut 17 between the two counter bearings 18.
  • the mounting flange 14 is screwed to the brake magnet in a known manner and the cylinder is attached at its other end to the vehicle.
  • a damping ring 19 is arranged, which is attached to the cylinder cover 12 in a known manner, for example glued or screwed tight in the embodiment according to FIG. 2.
  • the damping ring 19 has a square cross section and it consists of an elastomeric material which has a greater damping capacity than the material from which the bearing rings 15 and 16 are made.
  • the damping ring 19 has a lower Shore hardness than the bearing rings 15 and 16, for example a 2% lower hardness. If it is provided that the bearing rings 15 and 16 consist of different material, at least the counter bearing ring 16 must have a lower damping capacity than the damping ring 19 so that it can fulfill its task.
  • the damping ring 20 carries a metal support 21 on the side facing the cylinder cover as well as a metal support 22 on the side facing the fastening flange.
  • Both supports 21 and 22 consist of iron or a correspondingly acting material and are connected to the ring 20 vulcanized into one unit.
  • the one ring 21 projects beyond the outer contour 23 of the damping ring 20, at least partially. Bores 24 are provided in the protruding parts for receiving fastening screws.
  • the damping ring can also be used for centering, in that a circumferential bead is arranged on the cylinder cover 12 or the fastening flange 14, which carries roof-like centering surfaces, and the damping ring has corresponding recesses or is otherwise adapted to the centering surfaces of the bead. This ensures that when the mounting flange is attached to the cylinder cover (as shown in Fig. 1) when the Brake magnet of the mounting flange 14 centered in relation to the cylinder cover 21 and the guide for the piston rod 13 is not too heavily stressed by the vibrations occurring while driving.
  • the elastic mounting 14A, 15, 16 between the mounting flange and the cylinder cover can also be arranged on the other side of the cylinder 11.

Claims (5)

  1. Vérin de levage pour freins électro-magnétiques sur rails, avec lequel on peut abaisser, respectivement, lever le frein magnétique, chez lequel est disposé, entre le couvercle du vérin et la bride de fixation de la tige de piston, un anneau amortisseur (19) constitué par un matériau élastique, ou élastomère qui a un pouvoir amortisseur identique ou plus grand que les anneaux d'appui (15,16), caractérisé par le fait que les anneaux d'appui (15,16) possèdent une dureté identique, ou plus grande que l'anneau amortisseur (19) et que, l'anneau amortisseur (19) ayant une section carrée, les anneaux d'appui (15, 16) sont sous pré-tension.
  2. Vérin de levage suivant la revendication 1 ou 2, caractérisé par le fait que les anneaux d'appui (15,16) sont constitués par différents segments.
  3. Vérin de levage suivant l'une des revendications 1 à 4, caractérisé par le fait que, sur le couvercle du vérin (12), respectivement, sur le bride de fixation (14), est prévu un bourrelet à surfaces de centrage en forme de toit et dans l'anneau amortisseur (19), sont prévues des surfaces de centrage correspondantes.
  4. Vérin de levage suivant l'une des revendications 1 à 5, caractérisé par le fait que, sur la face regardant le couvercle du vérin (12) et/ou, regardant la bride de fixation (14) de l'anneau amortisseur (19), est appliquée, par ex. par vulcanisation, une couche divisée, ou non divisée en métal, en matière plastique, ou autre matière semblable.
  5. Vérin de levage suivant l'une des revendications 1 à 6, caractérisé par le fait que l'une des applications (21) ou (22) dépasse partiellement les contours extérieurs de l'anneau amortisseur (19) et que, dans la partie qui dépasse, sont aménagés des alésages (24) de fixation.
