Definitions

  • the invention relates to a frog tip, with its underside between Wing rails are movably arranged on a base such as a sliding chair and at one of the wing rails adjacent position or end position preferably by means of at least one locking clip received guided by a locking part can be locked.
  • the well-known movable centerpiece tips are on a sliding chair between their end positions moved back and forth to be locked when they are on a wing rail. It is due to the sliding on the sliding chair Requires frequent inspection and maintenance. Especially lubrication work is often required, the lubricant itself becoming one Can cause environmental pollution; see. "Die Eisenbahnschiene”, published by Wilhelm Ernst & Sohn, Berlin, Kunststoff, Düsseldorf, 1977, pages 336 and 337.
  • the present invention is based on the problem of a frog tip type described in the beginning so that a reduction in maintenance is possible without constructively complex measures or special materials are required for the pad and the centerpiece tip.
  • the object is achieved in that the frog tip in their positions on the wing rails supported by the pad and between the positions on the wing rails is spaced from the base.
  • the frog tip only in the end positions, So in the locked states, on which the support is supported like a sliding chair, whereas when moving from one to the other end position one Distance to the document is made. This results in a reduction in maintenance while saving lubricants.
  • a further development of the invention provides that the foot of the frog tip directly or indirectly an element that runs along or roughly has projection extending along the central axis of the frog tip, and that the element interacts with a roller element, the central axis of which is approximately or approximately runs in a plane of symmetry running between the wing rails. It can the element on the roller element side have a surface that consists of two outer concaves extending sections and a middle preferably plateau-like section is composed, which forms the projection.
  • the centerpiece tip is then raised and thus spaced from the base when the projection or its flanks over the Roller element slides.
  • the radii of curvature of the outer portions at least in the area adjacent to the central section, or approximately the radius of curvature correspond to the roller element.
  • the roller element is preferably different on at least two spring elements Characteristic curves is supported, with the one spring element essentially constant rigidity and the other spring element has a variable rigidity and the spring elements are mechanically coupled to one another in such a way that when Centerpiece loaded roller element each spring element an effective Has travel.
  • the invention is characterized in that the Spring elements extend on opposite sides of a carrier element and over a connecting element such as a screw can be adjusted in such a way that the distance between them can be adjusted that the damping effecting spring element with the variable rigidity the side of the carrier element facing away from the frog tip runs that the Spring element with the variable rigidity in such a way when the roller element is not loaded is attracted by the connecting element against the support member that a Spring action is excluded or essentially excluded, and that at loaded roller element of each of the spring elements usual additional loading and Has relief of the roller element receiving spring travel lengths.
  • the spring elements are, on the one hand, a suspension spring and, on the other hand a damping spring, at least the latter, but preferably both elastomer springs are.
  • the damping spring has a rigidity that is preferably is ten times smaller than that of the suspension spring.
  • the damping spring provides suspension and thus damping in both directions, so that the tip of the frog hits a surface how sliding chair is excluded.
  • the damping spring quick vibration reduction in the centerpiece tip itself evoked.
  • the working position of the roller elements is determined by the rigidity of the suspension spring, that is, the level at which the centerpiece tip rests.
  • the element having the projection is directly or indirectly from the Centerpiece tip, this is preferably a cuboid Section of locking clip receptacles connecting the frog tip Brackets formed.
  • the centerpiece tip rolls on the roller elements by the measures according to the invention when moving off, with a pivoting during movement from one end position to the other end position with the result that the Centerpiece tip is spaced from the base.
  • the frog tip lies against one of the wing rails Position on the roller element close to the wing rail and touches with the other roller element on its longitudinal edge facing away from the wing rail.
  • Another proposal of the invention provides that the locking clip preferably in the longitudinal direction of the frog tip slidably from a locking clip receptacle connected to the frog tip assumes that at least one roller element extends from the closure clip, which of one passing through the closure piece, perpendicular or almost perpendicular to Centerpiece longitudinal axis displaceable sliding element is detectable, and that that Roller element on a parallel or approximately parallel to the direction of displacement Sliding element extending support is supported, which in turn is stationary for Closure piece is arranged or starts from this.
  • Centerpiece tip the roller element in one of the sliding element and the support at least partially limited recording, so that a safe concern the centerpiece tip is guaranteed on one of the wing rails.
  • the tip of the frog is raised from the base. that when moving the frog tip, the roller element of a ramp-shaped Section of the sliding element is detected and raised.
  • the roller element itself preferably goes from one below one of the wing rails associated locking rail extending leg of the locking clip out.
  • two roller elements extend from the leg and that in each case a roller element is arranged in the end region of the leg.
  • each of the roller elements is in sections of the sliding element and the support like career-formed recordings set.
  • Locking plate receptacles are attached to the frog tip (10) via connecting plates (16) and (18) (20) and (22), each of which is parallel to the Axes (24) and (26) rotating clamps running along the longitudinal axis of the frog tip (28) and (30) go out, push through the locking pieces (32) and (34) by the Wing rails (12) and (14) associated closure rails (36) and (38) or other fasteners.
  • the brackets (28) and (30) are also in Movable in the longitudinal direction of the locking rails (36).
