Description

KRAFTFAHRZEUG , INSBESONDERE RENNSPORTFAHRZEUG , MIT SICHERUNGSSEILMOTOR VEHICLE, ESPECIALLY RACING VEHICLE, WITH LOCKING ROPE
Die Erfindung betrifft ein Kraftfahrzeug, insbesondere ein Rennsport-Fahrzeug, mit einer Radaufhängung oder einem Radträger oder einem anderen Anbauteil, die oder der oder das durch ein am Fahrzeug-Aufbau befestigtes Seil gegen Wegfliegen nach einem Bruch der Radaufhängung oder der An- bauteil-Befestigung gesichert ist.The invention relates to a motor vehicle, in particular a racing vehicle, with a wheel suspension or a wheel carrier or another attachment, which is secured against flying away by a rope attached to the vehicle body after a break in the suspension or attachment attachment is secured.
Bei Formel-1 -Rennfahrzeugen besteht die Vorschrift, dass die Radaufhängungen zusätzlich über Drahtseile am Monocoque gesichert oder befestigt werden, um auszuschließen, dass insbesondere bei Unfällen dieser Fahrzeuge eine Radaufhängung incl. des Rades vom Fahrzeug wegbricht und sich dann zu einem gefährlichen Geschoss entwickelt. Denkbar ist in diesem Zusammenhang, dass im Falle eines derartigen Unfalls das Drahtseil selbst auch noch reißen könnte und somit seine Sicherungsfunktion nicht erfüllen kann. Grundsätzlich kann diese Gefahr vermieden werden, indem das Drahtseil ausreichend dick bzw. zugfest oder reißfest gestaltet wird, jedoch können einer derartig massiven Gestaltung andere Kriterien entgegenstehen.In Formula 1 racing vehicles, there is a requirement that the wheel suspensions are additionally secured or fastened to the monocoque using wire ropes, in order to rule out that, in particular in the event of accidents involving these vehicles, a wheel suspension including the wheel breaks away from the vehicle and then develops into a dangerous projectile. In this context, it is conceivable that in the event of such an accident, the wire rope itself could also tear and thus cannot fulfill its safety function. In principle, this danger can be avoided by making the wire rope sufficiently thick or tensile or tear-resistant, however, other criteria may conflict with such a massive design.
Daher soll hiermit aufgezeigt werden, wie ein Reißen des die Radaufhängung oder den Radträger (oder andere Anbauteile) sichernden (und dabei vernünftig dimensionierten) Seiles mit ausreichender Sicherheit verhindert werden kann (= Aufgabe der vorliegenden Erfindung). Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass das Seil unter Zwischenschaltung eines energieabsorbierenden Mittels am Fahrzeugauf- bau und/oder an der Radaufhängung oder dem Radträger (oder dem An- bauteil) befestigt ist. Vorteilhafte Aus- und Weiterbildungen sind Inhalt der Unteransprüche.It is therefore intended to show how tearing of the rope securing the wheel suspension or the wheel carrier (or other add-on parts) can be prevented with sufficient certainty (= object of the present invention). The solution to this problem is characterized in that the rope with the interposition of an energy absorbing agent on the vehicle. construction and / or is attached to the wheel suspension or the wheel carrier (or the attachment). Advantageous training and further education are included in the subclaims.
Erfindungsgemäß soll somit der mit einem Brechen der Radaufhängung oder dgl. schlagartig auf das Seil/Drahtseil einwirkende Impuls reduziert werden, so dass die mechanische Belastung des Seiles und somit das Risiko, dass dieses Seil reißt, erheblich herabgesetzt wird. Diese Impulsreduktion ist am wirkungsvollsten dann erzielbar, wenn die (kinetische) Energie des vom Fahrzeug-Aufbau abgebrochenen Bauteiles (unter diesen Begriff soll ausdrücklich auch die Radaufhängung oder der Radträger fallen) nicht vollständig in das Seil eingeleitet, bzw. genauer nicht vollständig über das Seil in den Seil-Aufhängepunkt am Fahrzeug-Aufbau weitergeleitet wird. Diese Energie-Reduzierung erfolgt nun erfindungsgemäß dadurch, dass in der be- sagten Kraft-Weiterleitungskette (abgebrochenes Bauteil => Seil => Fahrzeug-Aufbau) an geeigneter Stelle ein geeignetes energieabsorbierendes Mittel vorgesehen ist.According to the invention, the impact acting suddenly on the rope / wire rope when the wheel suspension or the like breaks is reduced, so that the mechanical load on the rope and thus the risk that this rope breaks are considerably reduced. This reduction in momentum can be most effectively achieved when the (kinetic) energy of the component broken off from the vehicle body (this term should also explicitly include the wheel suspension or the wheel carrier) is not completely introduced into the rope, or more precisely not completely via the rope is forwarded to the rope suspension point on the vehicle body. This energy reduction is now carried out according to the invention in that a suitable energy-absorbing means is provided at a suitable point in the aforementioned force transmission chain (broken component => rope => vehicle body).
Es bestehen verschiedene Gestaltungsmöglichkeiten für dieses energieab- sorbierende Mittel. So kann in der genanten Kraft-Weiterleitungskette ein Stossdämpfer oder eine Feder-Dämpfer-Einheit vorgesehen sein, der/die dem abgebrochenen Bauteil nach Spannen des Seiles eine zusätzliche geringe Bewegungsfreiheit gewährt, wobei mit Ausnutzung dieser zusätzlichen Bewegungsfreiheit die gewünschte Energieabsorption erfolgt, und zwar im vorgesehenen Dämpferelement. Dabei kann auch ein geeignetes deformierbares Element (auch Deformationselement genannt) als derartiges Dämpferelement oder als energieabsorbierendes Mittel wirken. Ein soeben genanntes Deformationselement zeichnet sich bei entsprechender Gestaltung durch ein hohes Energieabsorptionsvermögen aus, d.h. es kann ein Grossteil der kinetischen Energie des abgebrochenen Bauteils im sog. Deformationselement bei Umformung desselben vernichtet werden, wobei die Tatsache, dass dieser Prozess irreversibel ist, keine Rolle spielt, nachdem der vorangegangene Bruch der Anbauteil-Befestigung oder der Radaufhängung ohnehin folgenschwer ist.There are various design options for this energy-absorbing agent. For example, a shock absorber or a spring-damper unit can be provided in the aforementioned power transmission chain, which gives the broken component additional little freedom of movement after tensioning the rope, the desired energy absorption taking place by utilizing this additional freedom of movement, specifically in provided damper element. A suitable deformable element (also called a deformation element) can also act as such a damper element or as an energy-absorbing means. A deformation element just mentioned is characterized by a high energy absorption capacity with a corresponding design, ie a large part of the kinetic energy of the broken component can be in the So-called deformation element can be destroyed when the same is deformed, the fact that this process is irreversible does not matter after the previous breakage of the attachment part or the wheel suspension is serious anyway.
In einer bevorzugten Ausführungsform kann dabei das Deformationselement als ein partiell geschwächtes Rohr ausgebildet sein, durch das das Seil hindurchgeführt ist und an dessen freiem Ende das der Radaufhängung oder dem Radträger (oder allgemein dem Bauteil/Anbauteil) abgewandte Seil- Endstück befestigt ist, während das Rohr mit seinem gegenüberliegenden Ende am Fahrzeugaufbau abgestützt ist. Ein derartiges bevorzugtes Ausführungsbeispiel ist in den beigefügten Prinzipskizzen stark vereinfacht dargestellt, wobei Fig.1 eine Teil-Ansicht von oben auf ein erfindungsgemäßes Rennsport-Fahrzeug zeigt und in Fig.3 der Schnitt A-A aus Fig.1 dargestellt ist. In Fig.2 ist ein möglicher Zustand schematisch dargestellt, wenn die Radaufhängung des Rennsport-Fahrzeuges gebrochen ist.In a preferred embodiment, the deformation element can be designed as a partially weakened tube through which the rope is passed and at the free end of which the rope end piece facing away from the wheel suspension or the wheel carrier (or generally the component / attachment) is fastened, while the Pipe is supported with its opposite end on the vehicle body. Such a preferred exemplary embodiment is shown in a very simplified manner in the attached schematic diagrams, in which FIG. 1 shows a partial view from above of a racing vehicle according to the invention and in FIG. 3 the section A-A from FIG. 1 is shown. A possible state is shown schematically in FIG. 2 when the wheel suspension of the racing vehicle is broken.
Mit der Bezugsziffer 1 ist der Fahrzeug-Aufbau (auch Monocoque genannt) eines Formel-1 -Rennfahrzeuges bezeichnet, an dem u.a. die Radaufhän- gung 2 des rechten Vorderrades 3 in üblicher Weise befestigt ist. Dies ist nicht detailliert dargestellt, da übliche sog. Lenker vorgesehen sind, die über geeignete Lager einerseits mit dem nicht separat dargestellten Radträger und andererseits mit dem Fahrzeug-Aufbau 1 verbunden sind. Wie eingangs erläutert wurde, ist die Radaufhängung 2 daneben zusätzlich über ein Seil 4 mit dem Fahrzeug-Aufbau 1 verbunden bzw. an diesem befestigt.The reference number 1 denotes the vehicle body (also called monocoque) of a Formula 1 racing vehicle on which, among other things, the wheel suspension 2 of the right front wheel 3 is fastened in the usual way. This is not shown in detail, since conventional so-called handlebars are provided, which are connected via suitable bearings on the one hand to the wheel carrier (not shown separately) and on the other hand to the vehicle body 1. As was explained at the beginning, the wheel suspension 2 is additionally connected to the vehicle body 1 via a cable 4 or fastened to it.
Konkret ist hier das geeignet an der Radaufhängung 2 befestigte Seil 4Specifically, the rope 4 suitably fastened to the wheel suspension 2 is here
(Drahtseil 4), das für diesen Einsatzfall geeignet dimensioniert ist, zunächst über ein Umlenkelement 5 und dann durch ein Rohr 6 hindurchgeführt, das sich hier innerhalb des Fahrzeug-Aufbaus 1 im wesentlichen in Fahrzeug- Längsrichtung erstreckt. Mit seinem dem Umlenkelement 5 zugewandten Ende 6a ist dieses Rohr 6 auf geeignete, nicht näher dargestellte Weise massiv am Fahrzeug-Aufbau 1 abgestützt bzw. ausreichend steif an diesem befestigt. Am gegenüberliegenden sog. freien Ende 6b des Rohres 6 ist das freie, der Radaufhängung 2 gegenüberliegende Ende des Seiles 4 befestigt.(Wire rope 4), which is suitably dimensioned for this application, is first passed through a deflection element 5 and then through a tube 6, which here is essentially inside the vehicle body 1 in vehicle Extends in the longitudinal direction. With its end 6a facing the deflecting element 5, this tube 6 is supported in a suitable, not shown manner, solidly on the vehicle body 1 or fastened to it with sufficient rigidity. At the opposite so-called free end 6b of the tube 6, the free end of the cable 4 opposite the wheel suspension 2 is fastened.
Erfolgt nun bei einem Unfall des fahrenden Fahrzeuges ein Bruch der Radaufhängung 2, so wird sich diese zusammen mit dem Rad 3 aufgrund der vorhandenen kinetischen Energie weiterbewegen wollen, während der Fahr- zeug-Aufbau 1 schlagartig abgebremst wird. Hierdurch bzw. durch den daraus resultierenden Impuls wird das Seil 4 schlagartig und extrem hoch auf Zug belastet, so dass ohne Zusatzmaßnahmen sogar ein Reißen des Seiles 4 nicht grundsätzlich ausgeschlossen werden kann. Hier sind nun jedoch Zusatzmaßnahmen vorgesehen, die diese Gefahr deutlich reduzieren, und zwar in Form des Rohres 6 bzw. allgemein eines Deformations- oder Dämpferelementes. Tritt dann der beschriebene Belastungsfall auf, so wird die Zugkraft im Seil 4 über den Anlenkpunkt am Rohrende 6b in das Rohr 6 eingeleitet, welches sich - wie bereits erwähnt - mit seinem gegenüberliegenden Ende 6a am Fahrzeug-Aufbau 1 abstützt. Das Rohr 6 ist nun derart gestaltet bzw. dimensioniert, dass sich das Rohr 6 durch diese aufgebrachte Belastung verformt, d.h. das Rohrende 6b wird unter Stauchung des Rohres 6 zum Rohr-Ende 6a hin verlagert oder verschoben. Die Stauchung des Rohres 6 vollzieht sich dabei energieverzehrend, so dass die im Seil 4 auf den durch das Rohr-Ende 6a gebildeten fahrzeugaufbau-seitigen Abstütz- punkt übertragene Zugkraft reduziert wird.If the wheel suspension 2 breaks in the event of an accident of the moving vehicle, it will want to continue to move together with the wheel 3 due to the kinetic energy present, while the vehicle body 1 is braked suddenly. As a result of this, or as a result of the resulting impulse, the rope 4 is suddenly and extremely heavily loaded under tension, so that even without breaking the rope 4, it cannot be ruled out in principle. However, additional measures are now provided here that significantly reduce this risk, specifically in the form of the tube 6 or generally a deformation or damper element. If the described load case then occurs, the tensile force in the cable 4 is introduced into the pipe 6 via the articulation point at the pipe end 6b, which, as already mentioned, is supported with its opposite end 6a on the vehicle body 1. The tube 6 is now designed or dimensioned such that the tube 6 is deformed by this applied load, i.e. the tube end 6b is displaced or shifted with compression of the tube 6 towards the tube end 6a. The compression of the tube 6 takes place in an energy-consuming manner, so that the tensile force transmitted in the cable 4 to the support point on the vehicle body side formed by the tube end 6a is reduced.
Um die gewünschte energieverzehrende Stauchung bzw. Deformation des als sog. Deformationskörper wirkenden Rohres 6 in günstiger Weise sicherzustellen, kann das Rohr 6 mit geeigneten Sollknickstellen versehen und/oder perforiert ausgebildet sein, d.h. die Rohrwand weist geeignete Schwachstellen auf. Bevorzugt ist die Auslegung so getroffen, dass sich das bevorzugt in einer Leichtmetall-Legierung ausgebildete Rohr 6 im geschilderten, unfallbedingten Belastungsfall ziehharmonikaartig zusammenschiebt und somit derart nachgiebig ist, dass das Seil 4 nicht überlastet wird.In order to ensure the desired energy-consuming compression or deformation of the tube 6, which acts as a so-called deformation body, in a favorable manner, the tube 6 can be provided with suitable predetermined bends and / or perforated, ie the tube wall has suitable ones Vulnerabilities. Preferably, the design is such that the tube 6, which is preferably formed in a light metal alloy, pushes together like an accordion in the described, accident-related load case and is therefore so flexible that the cable 4 is not overloaded.
Bevorzugt ist - wie Fig.3 zeigt, für die rechte Radaufhängung 2 und für die (nicht dargestellte) linke Radaufhängung ein eigenes Rohr 6 bzw. Deformationselement vorgesehen. Bei der Dimensionierung und Anordnung der verwendeten Bauteile sollte noch dafür Sorge getragen werden, dass die sich durch die Deformation des Rohres 6 ergebende zusätzliche freie Länge des Seiles 4 nicht zur Folge hat, dass der Fahrer 7 vom Vorderrad 3 getroffen wird, nachdem durchaus das Seil 4 mit der abgebrochene Radaufhängung 2 quasi auf einem Kreisbogen um das Umlenkelement 5 verschwenkt werden kann. Ein solcher möglicher Zustand mit entsprechend deformierten Rohr 6 ist in Fig.2 dargestellt, die eine Ansicht entsprechend Fig.1 mit gebrochener Radaufhängung 2 schematisch zeigt. Gegebenenfalls kann auch auf das Umlenkelement 5 verzichtet werden, wobei jedoch bei der hier vorteilhaften Anordnung des Rohres 6 und auch im Hinblick auf die Tatsache, dass dieses eine gewisse Länge aufweisen sollte, das Umlenkelement 5 nicht un- wesentlich ist. Im übrigen sind anstelle des vorgeschlagenen Rohres 6 auch andere Deformationselemente möglich, in denen die gewünschte Verzehrung der Energie bzw. Energieabsorption erfolgen kann. Bspw. kann ein geeigneter Stoßdämpfer vorgesehen sein. Im übrigen können auch andere Bauteile als die Radaufhängung (bspw. ein Heckflügel) in entsprechender Weise gesichert sein, wie überhaupt eine Vielzahl von Details insbesondere konstruktiver Art durchaus abweichend vom gezeigten Ausführungsbeispiel gestaltet sein kann, ohne den Inhalt der Patentansprüche zu verlassen. As shown in FIG. 3, a separate tube 6 or deformation element is preferably provided for the right wheel suspension 2 and for the left wheel suspension (not shown). When dimensioning and arranging the components used, care should also be taken to ensure that the additional free length of the rope 4 resulting from the deformation of the tube 6 does not result in the driver 7 being hit by the front wheel 3 after the rope has been hit 4 can be pivoted with the broken wheel suspension 2 quasi on a circular arc around the deflection element 5. Such a possible state with a correspondingly deformed tube 6 is shown in FIG. 2, which schematically shows a view corresponding to FIG. 1 with broken wheel suspension 2. If necessary, the deflection element 5 can also be dispensed with, but the deflection element 5 is not insignificant in the arrangement of the tube 6 which is advantageous here and also in view of the fact that it should have a certain length. Otherwise, instead of the proposed tube 6, other deformation elements are also possible in which the desired consumption of energy or energy absorption can take place. For example. a suitable shock absorber can be provided. In addition, other components than the wheel suspension (for example a rear wing) can be secured in a corresponding manner, as a multitude of details, in particular of a constructive nature, can be designed quite differently from the exemplary embodiment shown, without leaving the content of the claims.
