Description

Die Erfindung bezieht sich auf eine Vorrichtung zum federnden Unterstützen von beweglichen Weichenteilen einer Schienenweiche, mit einem federnd gelagerten Gleitteil oder wenigstens einer federnd gelagerten Rolle, durch welche der bewegliche Weichenteil von einem zugeordneten Gleitstuhl abgehoben ist, wobei die federnde Lagerung von wenigstens einem Schenkel eines U-förmigen Bügels gebildet ist.The invention relates to a device for resilient Supporting movable switch parts of a rail switch, with a spring-mounted sliding part or at least a spring-loaded roller, through which the movable Lever part is lifted off an associated slide chair, wherein the resilient mounting of at least one leg a U-shaped bracket is formed.

Aus der DE 27 29 692 C3 ist eine Einrichtung der eingangs genannten Art bekanntgeworden, welche eine federnde Gleiteinrichtung umfaßt. Bei dieser bekannten Ausbildung ist ein U-förmiges Federelement mit einem Schenkel starr mit einer Unterlage verbunden, wohingegen der freie Schenkel des U-förmigen Federelementes ein Gleitteil trägt. Unter dem Gewicht eines eine Weichenzunge überfahrenden Gleisfahrzeuges wird die Federkraft des Federelementes überwunden und die Weichenzunge liegt auf dem zugehörigen Gleitstuhl an. Während der Umstellbewegung derartiger Weichenzungen, welche naturgemäß nur im nicht befahrenen Zustand erfolgen darf, hebt das Federelement die Weichenzunge vom Gleitstuhl ab, sodaß lediglich die zwischen dem Gleitteil und der Zunge verbleibenden Reibungskräfte während des Umstellvorganges überwunden werden müssen. Bei dieser bekannten Ausbildung kann lediglich ein Schenkel des U-förmigen Federelementes eine Federkraft ausüben, da der zweite Schenkel starr an einer mit dem Fuß einer Backenschiene verbundenen Auflage festgelegt ist. Zur Erzielung der erforderlichen Federkraft ist somit ein relativ schweres Federelement erforderlich, wobei eine nachträgliche Justierung nach der Anordnung der Auflage an der Backenschiene nicht mehr möglich ist.From DE 27 29 692 C3 is a device of the aforementioned Art have become known which a resilient slide includes. In this known training is a U-shaped Spring element with a leg rigid with a Base connected, whereas the free leg of the U-shaped Spring element carries a sliding part. Under the weight a railroad crossing a railroad track vehicle is the Spring force of the spring element overcome and the switch blade lies on the associated sliding chair. During the Umstellbewegung such Weichenzungen, which naturally only allowed when not used, this raises Spring element, the switch blade from the sliding chair, so that only between the slider and the tongue remaining friction forces during the changeover process must be overcome. In this known training can only one leg of the U-shaped spring element a Spring force exert because the second leg rigidly with a fixed to the foot of a stock rail connected support is. To achieve the required spring force is thus a relatively heavy spring element required, with a subsequent adjustment after the arrangement of the support on the Back rail is no longer possible.

Aus der US-A 5 501 418 ist eine federnde Rolleinrichtung zu entnehmen, bei welcher eine Zungenschiene während des Umstellvorganges von federnden Rollen abgestützt wird, um die Verschiebekraft zu verringern.From US-A 5 501 418 is a resilient rolling device to remove, in which a tongue rail during the changeover process supported by resilient rollers to the displacement force to reduce.

Die Erfindung zielt nun darauf ab, eine Einrichtung der eingangs genannten Art zu schaffen, welche im Vergleich zu bekannten Ausbildungen wesentlich leichter ausgebildet sein kann, welche wesentlich einfacher aufgebaut ist und welche die Möglichkeit einer nachträglichen Justierung nach der Festlegung am Fuß eines starren Weichenteiles bietet. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Vorrichtung im wesentlichen darin, daß der U-förmige Bügel an dem dem Gleitteil bzw. der wenigstens einen Rolle abgewandten freien Ende eines Schenkels mit dem Schienenfuß eines unbeweglichen Weichenteiles oder dem Steg eines beweglichen Weichenteiles starr verbunden ist und daß beide Schenkel des U-förmigen Bügels relativ zum Schienenfuß oder dem Steg eines beweglichen Weichenteiles schwenkbar angeordnet sind. Dadurch, daß beide Schenkel des U-förmigen Bügels relativ zum Schienenfuß eines unbeweglichen Weichenteiles oder dem Steg eines beweglichen Weichenteiles schwenkbar angeordnet sind, stehen beide Schenkel des U-förmigen Bügels zur Ausübung der erforderlichen Federkraft zur Verfügung, sodaß insgesamt eine leichtere Bauweise gewählt werden kann, um den erforderlichen Federweg und die erforderliche Federkraft zu erzielen. Die Befestigung des U-förmigen Bügels an dem dem Gleitteil abgewandten freien Ende eines Schenkels erlaubt eine besonders einfache Festlegung unter Verwendung einer besonders geringen Anzahl von Bauteilen und es kann hier eine einfache Klemmverbindung vorgesehen sein. Da beide freien Schenkel gegenüber der Anlenkstelle, an welcher der U-förmige Bügel starr festgelegt ist, schwenkbar sind, kann mit einer derartigen Ausbildung in einfacher Weise eine nachträgliche Justierung und insbesondere eine Voreinstellung der Schwenklage mit besonders einfachen Mitteln erzielt werden.The invention now aims to provide a device of the initially mentioned type to create, which compared to be known much easier trained training can, which is much simpler and which the Possibility of a subsequent adjustment after the Fixing at the foot of a rigid soft part offers. to Solution of this task is the device according to the invention essentially in that the U-shaped bracket on the Sliding part or at least one roller facing away from the free end of a leg with the Rail foot of a immovable turnout or jetty a movable switch part is rigidly connected and that both legs of the U-shaped bracket relative to the rail foot or the web of a movable switch part pivotable are arranged. Characterized in that both legs of the U-shaped Stirrups relative to the rail foot of an immovable Soft part or the bridge of a movable switch part are pivotally mounted, stand both legs of the U-shaped Straps to exercise the necessary spring force Available, so that overall a lighter construction chosen can be the required travel and the required To achieve spring force. The attachment of the U-shaped Stirrups on the free end of the slider facing away from a Schenkels allows a particularly simple fixing under Use of a particularly small number of components and It can be provided here a simple clamp connection. There both free legs opposite the pivot point, at which the U-shaped bracket is fixed rigidly, are pivotable, can with such training in a simple way a subsequent adjustment and in particular a default setting achieved the pivotal position with very simple means become.

In besonders vorteilhafter Weise ist die erfindungsgemäße Ausbildung so getroffen, daß der U-förmige Bügel wenigstens einen den Schienenfuß umgreifenden Fortsatz trägt. Ein derartiger unmittelbar am U-förmigen Bügel angebildeter, einen Schienenfuß übergreifender Fortsatz erlaubt das gesamte Federelement einfach an den Fuß einer Schiene anzustecken, sodaß eine besonders einfache Festlegung gelingt. Die erforderliche Haltekraft beim Anklemmen an einen Schienenfuß kann in besonders einfacher Weise dadurch gewährleistet werden, daß der den Schienenfuß umgreifende Fortsatz federnd ausgebildet ist.In a particularly advantageous manner, the inventive design made such that the U-shaped bracket at least one carries the rail foot engaging extension. Such a directly at the U-shaped bracket angebildeter, a rail foot cross-extension allows the entire spring element simply to attach to the foot of a rail, so that one particularly simple determination succeeds. The required Holding force when clamping to a rail foot can in be ensured in a particularly simple manner that the extension encompassing the rail foot is resilient is.

Eine besonders einfache Verstellung der Schwenklage und damit Justierung der erfindungsgemäßen Vorrichtung gelingt, wenn, wie es einer bevorzugten Weiterbildung entspricht, die Ausbildung so getroffen ist, daß der den Schienenfuß umgreifende Fortsatz oder das mit dem Steg des beweglichen Weichenteiles verbundene Ende des Bügels über einen gekröpft ausgebildeten Abschnitt des Federbügels mittels einer Spannvorrichtung verbunden ist. Insgesamt können bei einer derartigen Ausbildung sowohl der den Schienenfuß umgreifende Fortsatz als auch der gekröpft ausgebildete Abschnitt einstückig aus dem Material des Federbügels gefertigt werden, wobei eine besonders einfache Spannvorrichtung in Form eines hakenförmigen Montagebügels ausgebildet ist, welche eine im Bereich des gekröpft ausgebildeten Abschnittes mit dem U-förmigen Bügel verbundene Versteifungsplatte hintergreift. Dadurch kann eine Grundverschwenkung des U-förmigen Bügels relativ zum Schienenfuß vorgegeben werden und damit die korrekte Einbaulage zur Erzielung der gewünschten Funktion gewährleistet werden. Die Versteifungsplatte folgt der Kontur des U-Bügels und enthält beispielsweise eine rechteckförmige Ausnehmung, um nun eine Verschraubung von oben zu ermöglichen. Damit wird die Federsteifigkeit des U-Bügels im Einspannbereich wesentlich erhöht, ohne Dimensionsänderungen am Bügel selbst vornehmen zu müssen.A particularly simple adjustment of the pivot position and thus Adjustment of the device according to the invention succeeds if as it corresponds to a preferred development, the training made such that the embracing the rail foot Extension or with the web of the movable switch part connected end of the strap over a cranked trained Section of the spring clip connected by means of a clamping device is. Overall, with such a training both of the rail foot encompassing extension and the Cranked section formed integrally from the material be made of the spring clip, with a particularly simple Clamping device in the form of a hook-shaped mounting bracket is formed, which one in the area of the cranked trained section associated with the U-shaped bracket Stiffening plate engages behind. This can cause a Grundverschwenkung the U-shaped bracket relative to the rail foot be given and thus the correct installation position for Achieving the desired function can be ensured. The Reinforcement plate follows the contour of the U-bracket and contains For example, a rectangular recess to now a To allow screwing from above. This is the spring stiffness significantly increased in the clamping area of the U-bracket, without having to make dimensional changes on the bracket itself.

In besonders einfacher Weise kann an einem freien Schenkel des U-förmigen Bügels nicht nur ein Gleitteil, sondern auch eine Rolle festgelegt werden. Um hier die entsprechende Einstellbarkeit und Anpassung an die gewünschte Form des Schienenfußes bzw. der Zungenschiene sicherzustellen, ist mit Vorteil die Ausbildung so getroffen, daß der das Gleitelement tragende freie Schenkel des Bügels in Längsrichtung des Schenkels geschlitzt ausgebildet ist und daß im Schlitz wenigstens eine Stützrolle in Längsrichtung des Schenkels verschiebbar und in ihrer Verschiebelage festlegbar gelagert ist. Auch hier kann somit ohne zusätzliche Bauteile dadurch, daß in einem der Schenkel des U-förmigen Bügels lediglich ein Schlitz vorgesehen ist, die entsprechende Lagerung für eine Rolle geschaffen werden, welche zu allem Überfluß in besonders einfacher Weise in Längsrichtung des Schenkels verschiebbar und ihrer Verschiebelage festlegbar gelagert sein kann.In a particularly simple manner can on a free leg of the U-shaped stirrups not only a slider, but also a Role be set. Here the appropriate adjustability and adaptation to the desired shape of the rail foot or to ensure the tongue rail is beneficial to the Training made such that the slider carrying the free legs of the strap in the longitudinal direction of the leg slotted is formed and that in the slot at least one Support roller slidable in the longitudinal direction of the leg and in its shift position is mounted fixed. Again, you can Thus, without additional components in that in one of Legs of the U-shaped bracket only one slot is provided, the corresponding storage for a roll to be created which to all abundance in particular easy way in the longitudinal direction of the leg displaced and its displacement position can be mounted fixed.

In besonders vorteilhafter Weise ist die Ausbildung hiebei so getroffen, daß die Stützrolle(n) über eine im Bereich der Krümmung des U-förmigen Bügels, insbesondere federnd, abgestützte Spindel in Längsrichtung des Schenkels verschiebbar ist (sind), wobei auch hier wiederum in besonders einfacher Weise eine einstückige Ausbildung aus dem Material des U-Bügels durch einfaches Ausbiegen von entsprechend ausgestanzten oder ausgeschnittenen Abschnitten möglich ist. Mit Vorteil ist die Ausbildung hiebei so getroffen, daß der den Schienenfuß übergreifende Fortsatz und gegebenenfalls der Stützteil für die Spindel einstückig aus dem Material des U-förmigen Bügels ausgebogen sind.In a particularly advantageous manner, the training hiebei so taken that the support roller (s) over in the range of Curvature of the U-shaped bracket, in particular resilient, supported spindle in the longitudinal direction of the leg displaceable is (are), and here again in particular simple way a one-piece design of the material of the U-bracket by simply bending out accordingly punched or cut sections is possible. Advantageously, the training hiebei made so that the the rail foot cross-extension and possibly the Support member for the spindle in one piece from the material of the U-shaped Straps are bent out.

Eine besonders einfache Ausbildung der verschieblichen Lager für eine in Längsrichtung eines Schenkels des U-förmigen Bügels verschiebbare Stützrolle läßt sich dadurch verwirklichen, daß die verschieblichen Lager der Stützrollen die Ränder des Schlitzes klauenförmig umgreifen, und insbesondere von einer an ihren Enden diametrale Nuten aufweisenden Lagerachse gebildet sind.A particularly simple design of the sliding bearing for a longitudinal direction of a leg of the U-shaped Bügel's sliding support roll can be realized thereby, that the slidable bearings of the support rollers the edges clasp the slot claw-shaped, and in particular of a bearing at its ends diametrical grooves bearing axis are formed.

Insgesamt wird auf diese Weise eine kompakte Baueinheit geschaffen, welche aus einem einzigen speziell geformten federnden Halteelement besteht, das in besonders einfacher Weise am Fuß einer Backenschiene befestigt werden kann und gleichzeitig als Trägerelement für Gleitelemente bzw. Rollelemente dient. Dadurch, daß das Federelement im Anschluß an die Festlegung an der Backenschiene keine weitere Auflage besitzt, gelangen sowohl der untere als auch der obere Schenkel des U-förmigen Federelementes als Federelement zum Einsatz, wobei die Formgebung des Grundkörpers erlaubt, ohne weitere gesonderte Halteelemente auszukommen. Im Bereich der Backenschiene können an diesem Bauteil an einer Seite Anschläge und auf der anderen Seite federnde Gegenbügel in Form eines übergreifenden Fortsatzes vorgesehen sein, sodaß die ganze Einrichtung ohne Werkzeuge unmittelbar am Fuß einer Backenschiene festgelegt werden kann. Durch die Spannvorrichtung bzw. die Spindel zum Verschieben von Stützrollen kann eine Einjustierung der Gleit- bzw. Rollelemente in horizontaler und vertikaler Richtung erfolgen, sodaß eine besonders einfache und betriebssichere und in weiten Grenzen einstellbare federnde Gleit- oder Rollagerung für Weichenzungen zur Verfügung steht.Overall, in this way a compact unit created from a single specially shaped resilient holding element consists, in a particularly simple Way can be attached to the foot of a stock rail and at the same time as a carrier element for sliding elements or Rolling elements is used. Due to the fact that the spring element in the connection to the determination on the stock rail no further support own, get both the lower and the upper Leg of the U-shaped spring element as a spring element for Use, whereby the shaping of the main body allows, without get along separate separate holding elements. Around Back bar can be attached to this component on one side Stops and on the other side springy stirrups in Form of an overarching extension be provided, so that the whole facility without tools right at the foot of a Backing rail can be fixed. Through the clamping device or the spindle for moving support rollers can a Einjustierung the sliding or rolling elements in horizontal and vertical direction, so that a particular simple and reliable and within wide limits adjustable elastic sliding or rolling bearing for Switch blades is available.
