Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Festlegen von Radlenkern, bei welcher der Radlenker frei von Durch­brechungen ausgebildet und von Klauen hintergriffen ist, welche Klauen an einem Befestigungsteil festgelegt sind.The invention relates to a device for fixing wheel control arms, in which the wheel control arm is free of openings and is engaged by claws, which claws are fixed to a fastening part.

Radlenker werden immer dann eingesetzt, wenn es erforderlich ist, ein Anfahren des Rades an anderen Gleisoberbauteilen, insbesondere Herzstücken oder einer Herzspitze zu vermeiden. Insbesondere bei starren Herzspitzen wird die Waggonachse durch das Rad auf der gegenüberliegenden Seite des Herz­stückes mittels eines Radlenkers geführt. Für die Festlegung von Radlenkern sind verschiedene Ausführungen bekannt und es ist beispielsweise bekannt, Radlenker in konventioneller Weise durch Schraubenverbindung an einem Radlenkerstuhl zu befestigen. Bei einer derartigen Ausbildung ist es erforder­lich, den Radlenker in bestimmten Abständen entsprechend der Schwellenteilung zu bohren. Da in verschiedenen Weichengeo­metrien verschiedene Schwellenteilungen zur Anwendung kommen, ist meist ein vorgebohrter Radlenker nur für eine bestimmte Weichengeometrie verwendbar. Radlenker lassen sich auch ohne derartige Bohrungen und ohne Durchschraubungen festlegen, wobei es beispielsweise aus der US-PS 947 317 bereits bekanntgeworden ist, Radlenker über Klauen mit einem Rad­lenkerstuhl zu verspannen. Bei der bekannten Konstruktion wurden die Klauen starr am Radlenkerstuhl durch eine Ver­schraubung festgelegt. Bei verschleißbedingter Vergrößerung der Radlenkerille bzw. einer entsprechenden Verkleinerung der Leitweite mußte allerdings der gesamte Radlenker getauscht werden, da Justierungen, bedingt durch die gewählte Geometrie der Festlegung, nicht ohne weiteres möglich waren.Wheel control arms are always used when it is necessary to avoid starting the wheel on other track components, especially frogs or a heart tip. In particular with rigid heart tips, the wagon axis is guided by the wheel on the opposite side of the heart piece by means of a wheel control arm. Various designs are known for fixing wheel control arms and it is known, for example, to fasten wheel control arms to a wheel control chair in a conventional manner by means of a screw connection. With such a design, it is necessary to drill the wheel control arm at certain intervals in accordance with the threshold division. Since different threshold divisions are used in different turnout geometries, a pre-drilled wheel control arm can usually only be used for a certain turnout geometry. Wheel links can also be fixed without such bores and without screwing through, it having already become known, for example from US Pat. No. 947,317, to clamp wheel links via claws with a wheel steering chair. In the known construction, the claws were fixed rigidly to the wheel steering chair by means of a screw connection. If the wheel steering groove was enlarged due to wear or the guide distance was reduced accordingly, the entire wheel steering had to be replaced, since adjustments were not readily possible due to the chosen geometry of the fixing.

Die Erfindung zielt nun darauf ab, eine Vorrichtung der eingangs genannten Art zu schaffen, bei welcher gegebenen­falls erforderliche Wartungsarbeiten rasch und mit geringstem Aufwand vorgenommen werden können und bei welchen unter Verzicht auf Durchbrechungen im Bereich des Radlenkers eine einfache Möglichkeit geboten wird, gewünschtenfalls den Radlenker durch Federspannung zu fixieren und abzustützen. Im besonderen zielt die erfindungsgemäße Ausbildung darauf ab, bei Verwendung von Federelementen Wartungsarbeiten, wie beispielsweise einen Federtausch, ohne aufwendige Hilfsmittel in kürzester Zeit vornehmen zu können.The invention now aims to provide a device of the type mentioned, in which any necessary maintenance work quickly and with the least Effort can be made and in which, without any openings in the area of the wheel control arm, a simple possibility is offered to fix and support the wheel control arm by spring tension if desired. In particular, the design according to the invention aims to be able to carry out maintenance work, such as a spring replacement, without using complex aids in a very short time when using spring elements.

Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Vorrichtung im wesentlichen darin, daß der Befestigungsteil eine sich parallel zur Längsrichtung des Radlenkers er­streckende Befestigungsplatte aufweist, daß die Klauen durch Durchbrechungen in der Befestigungsplatte hindurchführbar sind und an der dem Radlenker abgewandten Seite der Be­festigungsplatte, insbesondere unter Zwischenschaltung einer Feder, gegen die Befestigungsplatte spannbar sind. Dadurch, daß eine sich parallel zur Längsrichtung des Radlenkers erstreckende Befestigungsplatte vorgesehen ist, wird eine einfache und sichere Abstützung des Radlenkers quer zur Schienenlängsrichtung geboten und die Verspannung der Klauen gegen eine derartige Befestigungsplatte läßt sich rasch und mit geringstem Montageaufwand durchführen. Die sich parallel zur Längsrichtung des Radlenkers erstreckende Befestigungs­platte erlaubt darüberhinaus in einfacher Weise die Anordnung von Distanzstücken, um Verschleißerscheinungen des Radlenkers ohne Austausch des Radlenkers Rechnung tragen zu können und die geforderten lichten Weiten der Radlenkerrille bzw. die geforderte Leitweite mit einfachen Mitteln einzustellen. Die Art der Befestigung mit die Befestigungsplatte durchsetzenden Klauen ermöglicht auch in besonders einfacher Weise die Anordnung von Federn, um eine federbelastete Verspannung und somit eine sichere Abstützung der Radlenker zu erzielen, wobei die Ausbildung gleichzeitig die Möglichkeit bietet, die gewählte Federvorspannung ohne komplizierte Einstellarbeiten auch dann sicher wiederum einzustellen, wenn Distanzstücke zum Ausgleich der Vergrößerung der Radlenkerrille bzw. Verkleinerung der Leitweite durch Verschleiß eingesetzt werden.To achieve this object, the device according to the invention essentially consists in that the fastening part has a fastening plate extending parallel to the longitudinal direction of the wheel link, that the claws can be passed through openings in the fastening plate and on the side of the fastening plate facing away from the wheel link, in particular with the interposition of a Spring against which the mounting plate can be tensioned. Characterized in that a mounting plate extending parallel to the longitudinal direction of the wheel control arm is provided, a simple and safe support of the wheel control arm is provided transversely to the longitudinal direction of the rail, and the claws can be braced against such a mounting plate quickly and with minimal assembly effort. The mounting plate, which extends parallel to the longitudinal direction of the wheel control arm, furthermore allows the arrangement of spacers in a simple manner, in order to be able to take account of signs of wear of the wheel control arm without replacing the wheel control arm and to set the required clear width of the wheel control arm groove or the required guidance distance with simple means. The type of fastening with claws passing through the fastening plate also enables the arrangement of springs in a particularly simple manner in order to achieve spring-loaded bracing and thus secure support of the wheel control arm, the training at the same time offering the possibility of using the selected spring preload without complicated adjustment work again set safely when spacers be used to compensate for the enlargement of the wheel handlebar groove or the reduction of the guide distance due to wear.

Eine besonders rasche und sichere Festlegung läßt sich erfindungsgemäß dadurch erzielen, daß die Klauen an ihrem dem Radlenker abgewandten freien Ende eine Querbohrung für die Aufnahme eines Spannkeiles aufweisen. Derartige Spannkeile können mit Federn zusammenwirken, wobei durch das Eintreiben des Spannkeiles unmittelbar eine definierte Federkraft erzielt wird. Alternativ können derartige Spannkeile aber auch mit einem weiteren Keil zusammenwirken, wobei die Ausbildung bevorzugt so getroffen ist, daß der in die Quer­bohrung der Klauen eintreibbare Spannkeil mit einem eine der Keilfläche entsprechende selbsthemmend ausgebildete Fläche aufweisenden, gegen die Befestigungsplatte abstützbaren Keil zusammenwirkt. In diesem Fall wird allerdings nur eine starre, aber rasch herstellbare sichere Verbindung erzielt, wobei die gewünschte Spannkraft sich aus der eingeschlagenen Länge bzw. dem Übersetzungsverhältnis der Keile ergibt.A particularly rapid and secure fixing can be achieved according to the invention in that the claws have a transverse bore on their free end facing away from the wheel control arm for receiving a clamping wedge. Such clamping wedges can interact with springs, a defined spring force being achieved directly by driving in the clamping wedge. Alternatively, such clamping wedges can also cooperate with a further wedge, the design preferably being such that the clamping wedge which can be driven into the transverse bore of the claws interacts with a wedge which has a surface corresponding to the wedge surface and can be supported against the fastening plate. In this case, however, only a rigid, but quickly producible, secure connection is achieved, the desired clamping force resulting from the length taken or the gear ratio of the wedges.

Insbesondere für eine federbelastete Festlegung bietet die Verwendung von Quer- bzw. Vertikalkeilen als Spannkeile besondere Vorteile. Mit Vorteil ist die Ausbildung hiebei so getroffen, daß die Feder von wenigstens einer Blattfeder oder einer Schraubenfeder gebildet ist und daß der Keil mit Abstützflächen des Befestigungsteiles zur Ausübung einer Zugkraft auf die Klauen zusammenwirkt. Eine derartige Aus­bildung ergibt unmittelbar nach dem Eintreiben des Spann­keiles eine definierte Federkraft, wobei auf Grund der sich parallel zur Längsrichtung des Radlenkers erstreckenden Befestigungsplatte die vorgegebene Federkraft in einfacher Weise auch bei einem Nachstellen des Radlenkers auf Grund zunehmender Abnutzung sicher eingehalten werden kann. Zu diesem Zweck ist mit Vorteil die Ausbildung so getroffen, daß zwischen der Feder und der Befestigungsplatte lösbareThe use of transverse or vertical wedges as clamping wedges offers particular advantages, in particular for spring-loaded fixing. Advantageously, the training is so made that the spring is formed by at least one leaf spring or a helical spring and that the wedge cooperates with supporting surfaces of the fastening part to exert a tensile force on the claws. Such a design results in a defined spring force immediately after the clamping wedge has been driven in, and due to the fastening plate extending parallel to the longitudinal direction of the wheel control arm, the predetermined spring force can be reliably maintained in a simple manner even when the wheel control arm is adjusted due to increasing wear. For this purpose, the training is advantageously made such that detachable between the spring and the mounting plate

Distanzstücke angeordnet sind, welche zwischen Radlenker und Befestigungsplatte umsetzbar sind, wobei vorzugsweise die Dicke der Distanzstücke, in Richtung der Zugkraft auf die Klauen gemessen, dem maximal zulässigen Verschleiß der dem Spurkranz zugewandten Flächen des Radlenkers entspricht. Ein neuer Radlenker wird hiebei so eingebaut, daß die Distanz­stücke zwischen Feder und Befestigungsplatte angeordnet werden, wobei bei zunehmendem Verschleiß derartige Distanz­stücke aus dieser ursprünglichen Position in eine Lage zwischen der der Befestigungsplatte zugewandten Fläche des Radlenkers und der Befestigungsplatte eingeschoben werden können. Nach neuerlichem Eintreiben eines Spannkeiles wird unmittelbar die ursprünglich vorgegebene Spannkraft erzielt, so daß weitere Justierungsarbeiten entbehrlich sind.Spacers are arranged, which can be implemented between the wheel control arm and mounting plate, the thickness of the spacer elements, measured in the direction of the tensile force on the claws, preferably corresponding to the maximum permissible wear on the surfaces of the wheel control arm facing the wheel flange. A new wheel control arm is built in such a way that the spacers are arranged between the spring and the mounting plate, and with increasing wear, such spacers can be inserted from this original position into a position between the surface of the wheel control arm facing the mounting plate and the mounting plate. After driving in a clamping wedge again, the originally specified clamping force is immediately achieved, so that further adjustment work is not necessary.

Eine besonders stabile Konstruktion ergibt sich hiebei, wenn die Ausbildung so getroffen ist, daß die Befestigungsplatte einstückig mit der Unterlagsplatte bzw. Rippenplatte ausge­bildet ist und daß die Anschläge für den Spannkeil von Durchbrechungen in sich quer zur Befestigungsplatte er­streckenden, an die Befestigungsplatte anschließenden Stütz­platten des Befestigungsteiles gebildet sind. Eine einstücki­ge Ausbildung kann hiebei als Schweißkonstruktion ausgeführt sein, wobei die Befestigungsplatte gemeinsam mit dem Radstuhl auch als Gesenkschmiede- oder Gußkonstruktion ausgebildet sein kann.A particularly stable construction is obtained when the design is such that the fastening plate is formed in one piece with the base plate or ribbed plate and that the stops for the clamping wedge of openings in cross-sections of the fastening plate that extend transversely to the fastening plate and adjoin the fastening plate are formed. A one-piece design can be designed as a welded construction, the fastening plate, together with the wheel chair, also being able to be designed as a drop-forged or cast construction.

Die in Schienenlängsrichtung aufzunehmenden Kräfte werden bei einer derartigen Ausbildung als Friktions- bzw. Reibungs­kräfte zwischen Radlenker und der Befestigungsplatte aufge­nommen und die quer zur Schienenlängsrichtung auftretenden Kräfte werden vom Radlenker aufgenommen und direkt auf die Befestigungsplatte übertragen. Durchschubkräfte können aber nicht nur über Reibung von der sich parallel zur Längs­richtung des Radlenkers erstreckenden Befestigungsplatte, sondern auch vom Radlenkerstuhl in im wesentlichen vertikaler Richtung aufgenommen werden, wobei die Ausbildung bevorzugt so getroffen ist, daß der Befestigungsteil als Radlenkerstuhl ausgebildet ist, dessen dem Radlenker zugewandte Oberflächen Abstützflächen für den Fuß des Radlenkers ausbilden.With such a design, the forces to be absorbed in the longitudinal direction of the rail are absorbed as frictional or frictional forces between the wheel control arm and the fastening plate, and the forces occurring transversely to the longitudinal direction of the rail are absorbed by the wheel control arm and transmitted directly to the fastening plate. Thrust forces can be caused not only by friction from the mounting plate extending parallel to the longitudinal direction of the wheel control arm, but also from the wheel control chair in a substantially vertical direction Direction are recorded, the design preferably being such that the fastening part is designed as a wheel handlebar chair, the surfaces of which face the wheel handlebar form support surfaces for the foot of the wheel handlebar.

The support plates 8 have recesses 10 and 11 which are aligned with the transverse bore 9 of the claw and which, in addition to the leaf spring, can serve as stops when driving in the clamping wedge 6.

Auf der Rippenplatte bzw. Unterlagsplatte 7 ist weiters die mit dem Radlenker 1 zusammenwirkende Schiene 12 beispiels­weise über Verschraubungen 13 festgelegt, wobei die Fest­legung der Unterlagsplatte auf nicht näher dargestellten Schwellen über Verschraubungen 14 angedeutet ist. Anstelle der Verschraubung der Schienen können naturgemäß auch andere bekannte Verbindungselemente zwischen der Schiene 12 und der Unterlagsplatte bwz. Rippenplatte 7 Verwendung finden.On the ribbed plate or base plate 7, the rail 12 cooperating with the wheel control arm 1 is also fixed, for example via screw connections 13, the fixing of the base plate on thresholds, not shown, being indicated by means of screw connections 14. Instead of screwing the rails, other known connecting elements between the rail 12 and the base plate can of course also be used. Ribbed plate 7 is used.

Der aus der Befestigungsplatte 2 sowie den quer dazu ver­laufenden Stützplatten 8 gebildete Befestigungsteil bildet dabei den Radlenkerstuhl, wobei dem Radlenker zugewandte Oberflächen als Abstützflächen für den Fuß 15 des Radlenker­stuhles ausgebildet sind.The fastening part formed from the fastening plate 2 and the support plates 8 running transversely thereto forms the wheel handlebar chair, the surfaces facing the wheel handlebar being designed as support surfaces for the foot 15 of the wheel handlebar chair.

Die bei der Ausbildung gemäß den Fig.1 und 2 verwendete Blattfeder 4 stützt sich auf der dem Radlenker 1 abgewandten Rückseite der Befestigungsplatte unter Zwischenschaltung der Distanzstücke 5 ab und preßt über den Spannkeil 6 und die Klaue 3 den Radlenker 1 an die Vorderseite der Befestigungs­platte. Normalkräfte auf den Radlenker 1 werden dabei direkt auf die Befestigungsplatte abgeleitet. Durchschubkräfte werden über Reibung auf die Befestigungsplatte 2 übertragen.The leaf spring 4 used in the design according to FIGS. 1 and 2 is supported on the rear side of the fastening plate facing away from the wheel control arm 1 with the interposition of the spacers 5 and presses the wheel control arm 1 onto the front side of the fastening plate via the clamping wedge 6 and the claw 3. Normal forces on the wheel control arm 1 are derived directly on the mounting plate. Thrust forces are transmitted to the mounting plate 2 via friction.

Um auch bei einem abgenutzten Radlenker 1 die erforderliche Radlenkerrille, d.h. den Abstand zwischen Radlenker und Schiene, welche in Fig.1 schematisch mit d angedeutet ist, und somit eine konstante Leitweite, welche den Abstand zwischen dem Radlenker und der nicht dargestellten Herzspitze bezeichnet, gewährleisten zu können, werden die Distanzbleche 5 in verschiedenen Stärken und entsprechender Anzahl einge­baut und mitverspannt.In order to obtain the required wheel handlebar groove, ie the distance between wheel handlebar and rail, which is schematically indicated by d in FIG. and thus to be able to ensure a constant guide distance, which denotes the distance between the wheel control arm and the heart tip (not shown), the spacer plates 5 are installed in different thicknesses and corresponding numbers and are also braced.

Im neuen Zustand des Radlenkers 1 befinden sich die Distanz­bleche 5 an der dem Radlenker 1 abgewandten Seite der Be­festigungsplatte zwischen dieser und der Blattfeder 4. Mit zunehmender Abnutzung des Radlenkers und einer somit beding­ten Vergrößerung der Radlenkerrille d bzw. einer damit einhergehenden Verkleinerung der Leitweite wird der Radlenker durch Entfernung des Spannkeiles 6 gelöst und es werden eine entsprechende Anzahl der Distanzbleche 5 zwischen dem Rad­lenker 1 und der Befestigungsplatte 2 positioniert, wodurch wiederum die richtige Leitweite und Radlenkerrille einge­stellt wird. Die Größe der Verspannung der Blattfeder 4 und somit der Anpreßdruck des Radlenkers 1 bleiben damit gleich, da der effektive Abstand zwischen dem Radlenker 1 und der Ebene der Blattfeder durch Umsetzung der Distanzstücke 5 aus der in Fig.1 dargestellten Position in eine Position zwischen dem Radlenker 1 und der Befestigungsplatte 2 nicht geändert wurde.In the new state of the wheel control arm 1, the spacer plates 5 are located on the side of the mounting plate facing away from the wheel control arm 1 between the latter and the leaf spring 4. With increasing wear and tear of the wheel control arm and a consequent enlargement of the wheel control arm groove d or an associated reduction in the guidance distance, the The wheel control arm is released by removing the clamping wedge 6 and a corresponding number of the spacer plates 5 are positioned between the wheel control arm 1 and the mounting plate 2, which in turn sets the correct guide distance and wheel control arm groove. The size of the tension of the leaf spring 4 and thus the contact pressure of the wheel control arm 1 thus remain the same, since the effective distance between the wheel control arm 1 and the plane of the leaf spring by converting the spacers 5 from the position shown in FIG. 1 into a position between the wheel control arm 1 and the mounting plate 2 has not been changed.

Die Befestigungsplatte 2 ist im vorliegenden Fall mit der Rippenplatte bzw. Unterlagsplatte 7 sowie den Stützplatten 8 verschweißt. Alternativ könnte auch eine Gesenkschmiede- oder Gußkonstruktion Verwendung finden.In the present case, the fastening plate 2 is welded to the rib plate or base plate 7 and the support plates 8. Alternatively, a drop forged or cast construction could also be used.

Die Durchbrechung in der Befestigungsplatte 2 zum Durchtritt der Klaue 3 ist in Fig.1 mit 16 bezeichnet, während eine ent­sprechende Durchtrittsöffnung in der Blattfeder sowie in den Distanzstücken mit 17 bzw. 18 bezeichnet sind.The opening in the mounting plate 2 for the passage of the claw 3 is denoted by 16 in FIG. 1, while a corresponding passage opening in the leaf spring and in the spacers is denoted by 17 and 18, respectively.

Bei der Ausbildung gemäß den Fig.3 und 4 wurden für gleiche Bauteile die Bezugszeichen der Fig.1 und 2 beibehalten.3 and 4, the reference numerals of FIGS. 1 and 2 have been retained for the same components.

Anstelle der Verwendung einer Blattfeder zum Anpressen des Radlenkers 1 an die Befestigungsplatte 2 findet bei dieser Ausführungsform ein Federring bzw. eine Spiralfeder 19 Verwendung, welche wiederum über den Spannkeil verspannt wird, wobei der Spannkeil die Ausnehmungen 10 und 11 der Stützplatten 8 durchdringt.Instead of using a leaf spring to press the wheel control arm 1 onto the mounting plate 2, a spring ring or a spiral spring 19 is used in this embodiment, which in turn is clamped over the clamping wedge, the clamping wedge penetrating the recesses 10 and 11 of the support plates 8.

Bei der Ausbildung gemäß den Fig.5 und 6 wird der Radlenker 1 über zwei selbsthemmende Keile an die Befestigungsplatte 2 angepreßt. Dabei findet wiederum ein Querkeil 6 Verwendung, welcher mit einem zweiten Keil 20, welcher normal auf die Eintreibrichtung des Querkeiles 6 verläuft, zusammenwirkt. Der Querkeil bzw. Spannkeil 6 wird in die Bohrung 9 der Klaue 3 bzw. in die Bohrungen 10 und 11 der Stützplatten 8 einge­trieben und durch Abstützung des zweiten normal dazu ver­laufenden Keiles 20 an der dem Radlenker 1 abgewandten Fläche der Befestigungsplatte wird der Radlenker 1 über die Klaue 3 an die Vorderseite der Befestigungsplatte 2 gepreßt. Dabei finden wiederum Distanzstücke 5 Verwendung, welche bei fortschreitender Abnutzung aus der in Fig.5 dargestellten Position zwischen der Befestigungsplatte und dem zweiten Keil 20, analog wie bei den vorangehenden Ausführungsformen, in eine Position zwischen der dem Radlenker zugewandten Seiten­fläche der Befestigungsplatte 2 und dem Radlenker 1 ange­ordnet werden.In the embodiment according to FIGS. 5 and 6, the wheel control arm 1 is pressed against the fastening plate 2 by means of two self-locking wedges. Here again, a cross wedge 6 is used, which interacts with a second wedge 20, which extends normally to the driving direction of the cross wedge 6. The cross wedge or clamping wedge 6 is driven into the bore 9 of the claw 3 or into the bores 10 and 11 of the support plates 8 and by supporting the second wedge 20 which runs normally thereto on the surface of the fastening plate facing away from the wheel control arm 1, the wheel control arm 1 becomes over the claw 3 pressed against the front of the mounting plate 2. Here again spacers 5 are used, which as the wear progresses from the position shown in FIG. 5 between the mounting plate and the second wedge 20, analogously to the previous embodiments, into a position between the side face of the mounting plate 2 facing the wheel control arm and the wheel control arm 1 can be arranged.

Gemäß der eingeschlagenen Länge bzw. dem Übersetzungsver­hältnis der beiden Keile 6 bzw. 20 wird eine entsprechende Verspannung erreicht.A corresponding tension is achieved in accordance with the length taken or the gear ratio of the two wedges 6 and 20.

Bei der in Fig.7 und 8 dargestellten Ausführungsform durch­dringt die Klaue zur Halterung des Radlenkers 1 am von der Befestigungsplatte 2 und den Stützplatten 8 gebildeten Radlenkerstuhl wiederum die Durchbrechung 16 der Befesti­gungsplatte 2 und hintergreift den Fuß 15 des Radlenkers 1. Die Verspannung und Festlegung des Radlenkers 1 erfolgt bei dieser Ausführungsform durch eine Schraubverbindung 21, wobei zwischen den Distanzstücken 5 und der Mutter 21 ein Federring bzw. ein ähnliches Federelement 22 Verwendung findet. Der dem Radlenker 1 abgewandte Teil der Klaue 3 ist dabei mit einem entsprechenden Gewinde versehen. Bei dieser Ausbildung wird der Federring 22 über die Mutter 21 verspannt und der Rad­lenker 1 über die Klaue 3 wiederum an die Befestigungsplatte 2 gepreßt. Bei fortschreitendem Verschleiß des Radlenkers werden zur Einstellung der geforderten Radlenkerrille bzw. zur Aufrechterhaltung einer konstanten Leitweite wiederum die Distanzstücke in oben genannter Weise umgesetzt.In the embodiment shown in FIGS. 7 and 8, the claw for holding the wheel control arm 1 on the wheel control chair formed by the mounting plate 2 and the support plates 8 in turn penetrates the opening 16 of the mounting plate 2 and engages behind the foot 15 of the wheel control arm 1. The bracing and fixing of the Radlenkers 1 takes place at this embodiment by a screw connection 21, a spring ring or a similar spring element 22 being used between the spacers 5 and the nut 21. The part of the claw 3 facing away from the wheel control arm 1 is provided with a corresponding thread. In this embodiment, the spring ring 22 is clamped over the nut 21 and the wheel link 1 is again pressed onto the fastening plate 2 via the claw 3. As the wheel control arm continues to wear, the spacers are again implemented in the above-mentioned manner in order to set the required wheel control arm groove or to maintain a constant guide distance.

Durch den Verzicht von Bohrungen im Radlenker 1 und durch die Festlegung desselben an dem von der Befestigungsplatte 2 und den Stützplatten 8 gebildeten Radlenkerstuhl mittels durch die Befestigungsplatte 2 hindurchtretende Klauen 3 wird zum einen eine einfache Montage ermöglicht und es kann trotz einer Vielzahl von verwendeten Weichengeometrien durch den Wegfall der Bohrungen zur Festlegung der Radlenker an Rad­lenkerstühlen mit einer geringen Anzahl unterschiedlicher Radlenker das Auslangen gefunden werden. Weiters ergibt sich durch die Zwischenschaltung und unterschiedliche Positio­nierungsmöglichkeit der Distanzstücke 5 die einfache Möglich­keit, einem fortschreitenden Verschleiß des Radlenkers Rechnung zu tragen, wobei die Dicke der Distanzstücke normal auf die Achsen der Klaue 3 gemessen dem maximal zulässigen Verschleiß der dem Spurkranz zugewandten Flächen des Rad­lenkers entspricht.By dispensing with bores in the wheel control arm 1 and by fixing the same on the wheel control chair formed by the mounting plate 2 and the support plates 8 by means of claws 3 passing through the mounting plate 2, on the one hand simple installation is possible and despite a large number of switch geometries used, the omission of the holes for fixing the wheel handlebars on wheelchair chairs with a small number of different wheel handlebars can be found. Furthermore, the interposition and different positioning options of the spacers 5 result in the simple possibility of taking into account progressive wear on the wheel control arm, the thickness of the spacer arms measured normally on the axles of the claw 3 corresponding to the maximum permissible wear on the surfaces of the wheel control arm facing the wheel flange .
