Definitions

  • the invention relates to a roller device for a tongue of a switch associated with a cheek rail that originates indirectly or directly from a support such as a threshold, and comprises at least one roller element that is intended to support the tongue and that is indirectly or directly spring-supported.
  • rollers To reduce the friction when adjusting switch tongues, these can be stored on rollers. It is known that two roller elements start from a holder, on which a tongue to be opened is supported in sections. Bracket and roller elements are at a fixed distance from the stock rail to be arranged on the bracket. Since the distance between the stock rail and the open tongue decreases from the tip of the tongue to the root of the tongue, a large number of different roller devices are required in order to enable support.
  • roller bearing for switch tongues.
  • the roller bearing used has a purely supporting function.
  • the roller itself is mounted in a roller block, which is arranged in a cage of a bearing block. Since the spring does not dampen, there can be knocks between the roller block and the bearing block. This in turn leads to shock loads on the tongue.
  • a switch tongue is supported on a roller, which in turn is held by a rod spring assembly.
  • a switch tongue according to DE-OS 1 658 366 is supported on rollers extending from a roller block.
  • the problem underlying the present invention is to ensure that the switch tongue does not hit a support such as a sliding chair even when vibration is excited.
  • roller element is supported on at least two spring elements of different characteristics, that the one spring element has a substantially constant stiffness and the other spring element has a variable stiffness and that the spring elements are mechanically coupled to each other in such a way that at Tongue-loaded roller element, each spring element is elastically deformable.
  • the invention is characterized in that the spring elements extend on opposite sides of a carrier element and can be changed in distance via a connecting element such as a screw are adjustable to each other that the damping spring element with the variable stiffness runs on the side of the support element facing away from the tongue, that the spring element with the variable stiffness when the roller element is unloaded is tightened by the connecting element against the support element in such a way that a spring effect is excluded or im is essentially excluded, and that when the roller element is loaded, each of the spring elements has usual additional loading and unloading of the roller element absorbing spring travel lengths.
  • a connecting element such as a screw
  • 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, being elastomer springs.
  • the damping spring has a stiffness that is preferably ten times smaller than that of the suspension spring.
  • the damping spring When prestressing the spring elements, i.e. when the roller element is not loaded, the damping spring is set to block or almost to block, in order then to get into a working position (working point) with the roller element loaded by the tongue (working point), which makes it possible for conventional Loading and unloading of the roller element by the tongue acting on this the pre-stress point, that is, the block position is not reached.
  • the damping spring provides suspension and thus damping in both directions, so that an effective opening of the tongue on a surface such as a sliding chair is excluded.
  • vibration in the tongue itself is reduced quickly evoked.
  • the rigidity of the suspension spring determines the working position of the roller elements, that is, the level at which the tongue comes to rest.
  • the roller element can start from a receptacle in which the tongue, e.g. can be positively fixed.
  • the recording itself can be connected to the stock rail in the usual way, but preferably with the support such as a threshold. The latter measure causes a further decoupling from the stock rail.
  • FIG. 1 and 2 illustrate that, based on the teaching according to the invention, a switch tongue (114) to be mounted or displaced on the roller elements (90), (92) and (94) is damped to such an extent that striking occurs Documents such as sliding chairs are excluded. At the same time, this ensures that the roller elements (90), (92) and (94) do not have any impact-like impacts leading to destruction, a disadvantage which is inherent in the roller elements which can be found in the prior art.
  • roller elements (90), (92) and (94) which can be seen in FIG. 2 and a further roller element (96) are based on a receptacle (98) which, in side view, has a shape of a lying Us with different leg lengths.
  • the longer leg (100) faces a holder (106).
  • the receptacle (98) is supported on spring devices (102) and (104), which in turn are fastened on the holder (106), which in the exemplary embodiment is based on a threshold (110).
  • the holder (106) can be moved in the direction of or from a stock rail (108).
  • side legs of the holder (106) have elongated holes (112) which can be penetrated by fastening elements such as screws, which connect the holder (106) to the threshold (110).
  • the receptacle (98) itself preferably consists of two cheeks having the U-shape, in which the roller elements (90), (92), (94) and (96) are mounted and which are connected, for example, by a flat section which is on the spring devices (102) and (104) is attached.
  • FIG. 2 shows a switch tongue (114) to be assigned to the stock rail (108) on the one hand in the adjacent (strong solid line) and on the other hand in the remote position (weak solid line).
  • a section of the switch tongue foot (116) rests between the rollers (94) and (96), that is to say between the short leg (118) and the long leg (100) of the U-shaped receptacle (98) of the roller elements in side view (90), (92), (94) and (96).
  • This measure has the effect that the switch tongue (114) is also virtually locked in the remote position in order to prevent it from striking.
  • Each spring device (102) or (104) consists of an upper and a lower plate element (124) and (126), preferably made of metal, and a support plate (128) running between them, which starts from the holder (106).
  • Spring elements (122) and (120) of different stiffnesses extend between the carrier plate (128) and the upper plate (124) on the one hand and between the carrier plate (128) and the lower plate (126) facing away from the stock rail (108).
  • the stiffnesses of the spring elements (120) and (122), which are elastomer springs, which are connected to the plates (124), (126), (128) or to portions, but not specified, starting from them, but vulcanized are shown in the appendix of FIG. 1a.
  • the spring elements (120) and (122) are mechanically coupled by a connecting element. This passes through the spring devices (120) and (104) centrally.
  • a connecting element This passes through the spring devices (120) and (104) centrally.
  • it is a screw (130) which rests with its plate-shaped head (132) on the outside of the plate (124) and its nut (134) lies on the outside of the plate (126) in order to tighten it Screw (130) to set the effective length of the screw (130) between the plates (124) and (126).
  • the spring element (120) is a damping spring with variable stiffness.
  • the spring element (120) preferably has a progressive characteristic, as the left part of FIG. 1a is intended to illustrate.
  • the upper spring element (122), which is close to the stock rail (108), has a spring characteristic with constant rigidity and is intended to perform the actual carrying function.
  • the spring device (102), (104) has a position that corresponds to FIG. 1b.
  • the plates (124) and (126), from which the suspension spring (122) and the damping spring (120) extend, are spaced apart from the support plate (128).
  • this state coincides with the coordinate origin of the diagram together, in which the force (tension / load) is plotted against the travel.
  • FIG. 1d The position in which the switch tongue (114) is supported on the roller elements (90), (92), (94) is shown purely schematically in FIG. 1d.
  • the damping spring (120) is relieved by a spring travel - 5 units in FIG.
  • the suspension spring (122) is tensioned by the same spring travel, i.e. by 5 travel units in the drawing. This position corresponds to point 3 in Fig. 1a, which is the working point.
