Definitions

  • the invention relates to a slider, in particular of rail vehicles, which horizontal relative movements in the longitudinal and transverse direction between the car body and drive or between drive parts allows each other, wherein between the relatively moving parts vertically acting springs are arranged and the spring-loaded slider on a sliding plate, the horizontal relative movements dampens.
  • a solid sliding plate is usually provided, which is supported on a sprung slider.
  • the sprung slider is provided in the known embodiments with spring elements that a vertical deflection of this elastic slider to a limited extent enable.
  • the arrangement of a spring element for vertical compliance of the slider, the arrangement of additional guides is required so that the slider is accurately guided in the relative movements of the bogie to the car body.
  • a direct acting rotation inhibition between car body and drive is from the DE-C-2815375 ( EP-A-0004585 ) and DE-A-2842211 known, in which the fixed sliding plate, as known, are formed with a flat sliding surface and the resilient slider with approximately convex sliding surface, wherein the resilient slider consists of a supported only at their longitudinal ends leaf spring, which is stored without play.
  • a disadvantage of these known designs is the simultaneous friction of the sliders in the longitudinal and transverse directions. While in the longitudinal direction some obstruction of the Ausftouch the drive is desirable to avoid a lurching drive and thus instability, a softer connection of the car body for better decoupling the drive is desired in the transverse direction to avoid resonances and thus Laufgütemi whether.
  • Such a device is from the EP 0 362 329 B1
  • the friction of the slider on the sliding plate in one of the two horizontal directions is canceled by mounting the slider on coupling elements, which limits unimpeded or almost unhindered sliding of the slider in one of the two horizontal directions (longitudinal direction). or transverse) and fix the slider immovably in the other of the two horizontal directions.
  • the slider is firmly connected in the longitudinal direction and acts via its abutment directly and clearance auscordhemmend, while the slider is limited in the other of the two directions, freely displaced and thus ensures unimpeded connection in this direction.
  • the GB 608 937A describes an arrangement with a leaf spring for suspending wheels for a vehicle, in which the two ends of the leaf spring are mounted spherically movable on the vehicle frame. As a result, an additional relative movement of the leaf spring about its axis is to be achieved.
  • the present invention therefore an object of the invention was to find a slider that requires a relatively low transverse force to the recess when entering the rail arch and on the other hand ensures stable running properties in straight-ahead.
  • the slider is mounted spherically movable at the longitudinal ends of the leaf spring designed as springs.
  • a ball head is arranged at the longitudinal ends of the leaf support spring facing up, on which the slider is mounted with a lower spherical cap.
  • This arrangement of the slider ensures that the ideas generated when running straight of the rail vehicle suggestions for rolling the drive are effectively damped and tilting of the slider on its counter plate are avoided in vertical bumps of the track. Both the longitudinal and the transverse movements of the drive under the car body are dosed effectively metered.
  • the arrangement of the sliders on the longitudinal ends of the leaf support springs also a simple and economical damping is shown, which requires only a few components and can be adjusted in doses.
  • the ball head is integrally formed on the longitudinal ends of the blade support spring.
  • the ball head is formed as a separate component, which is attached to the longitudinal ends of the Blattragfeder.
  • the slider carries laterally downwardly facing webs, which project beyond the blade support spring down, wherein in the webs transversely below the Blattragfeder a sliding piece against lifting securing bolt is arranged.
  • the safety bolt is arranged with vertical and horizontal longitudinal clearance relative to the leaf spring or the ball head. This safety bolt prevents inadvertent loss of the slider when lifting the car body from the drive.
  • the slider consists of a support plate which carries a friction plate on its upper side immovably and in which under the bottom vertically arranged with a sliding insert spherical cap is arranged.
  • the invention is explained with reference to an embodiment.
  • On the drive frame (1) near the transverse ends of a leaf support spring (2) is mounted centrally on food pieces (13).
  • the Blattragfeder (2) carries at its longitudinal ends depending on an upwardly facing ball head (3) on which from a support plate (4) and a friction plate (5) existing slider is mounted spherically, which under a counter-plate (6) of the car body (6) 7) is longitudinally and transversely displaceable.
  • the ball head (3) is designed as a pushed onto the longitudinal end of Blattragfeder (2) and there fastened fork, arranged on the upper fork part of the ball head (3) and in the lower fork part a transverse to Blattragfeder (2) extending recess (12) is.
  • the support plate (4) has at the bottom center with a sliding insert (8) provided spherical cap (9) in which the ball head (3) is mounted. Laterally on the support plate (4) of the slider are pointing down webs (10) arranged near their lower longitudinal ends transversely to the Blattragfeder (2) a safety pin (11) inside the recess (12) of the lower fork part of the ball head ( 3) runs and the slider (4, 5) secures against lifting.
