Die Erfindung bezieht sich auf ein gefedertes Fahrzeugrad, das mit einem ader mit mehreren elastischen Ring (en) aus Gummi od. dgl. versehen ist, die zwischen an der Nabe und an der den Luftreifen tragenden Felge befestigten Scheiben anvulkanisiert sind.The invention relates to a sprung vehicle wheel with a vein with several elastic Ring (s) made of rubber od Discs attached to the rim are vulcanized.

Derartige Räder eignen sich zur Abfederung von Fahr-,. Motorrädern und auch von Kraftwagen. Die Eigenfederung solcher Räder ist zum Ausgleich einer ungenügenden Federung des Fahrzeuges in vielen Fällen vorteilhaft.Such wheels are suitable for cushioning driving ,. Motorcycles and also from motor vehicles. the Natural suspension of such wheels is used to compensate for insufficient suspension of the vehicle in many Cases advantageous.

Es sind selbstfedernde Fahrzeugräder bekannt, bei denen die zwischen Scheiben anivulkanisierten elastischen Ringe aus Gummi od. dgl. cine größere axiale Länge als radiale Stärke aufweisen. Dabei sind eine oder mehrere dieser Scheiben mit der Nabe verbunden, während eine oder mehrere andere Scheiben mit der Felge in Verbindung stehen. Die mit der Felge verbundenen Scheiben werden in radialer Richtung nachgiebig an den mit der Nabe verbundenen Scheiben geführt. Diese Führung erfordert nicht nur einen zusatzliehen Aufwand an Werkstoff, Gewicht, Herstellungskosten und Wartung, sondern beeinträchtigt auch die Fahreigenschaften des Fahrzeuges, insbesondere beim Durchfahren von Kurven.Self-resilient vehicle wheels are known in which the elastic vulcanized between discs Rings made of rubber od. The like. Have a greater axial length than radial thickness. There are one or more of these disks are connected to the hub, while one or more other disks are connected to the Rim related. The ones connected to the rim Disks are guided flexibly in the radial direction on the disks connected to the hub. This leadership not only requires additional expenditure in terms of material, weight, and manufacturing costs and maintenance, but also affects the driving characteristics of the vehicle, especially when Driving through curves.

Schließlich sind auch gefederte Fatirzeugräder bekannt,, bei denen zwischen an 'der Felge und an der Nabe befestigten Scheiben Gummiringe etwa quadratischen Querschnitts vorgesehen sind, die die einzige Verbindung zwischen den Scheiben der Nabe mit der der Felge darstellen. Diese Gummiringe ermöglichen nicht nur eine radiale Beweglichkeit der Felge gegenüber der Nabe, sondern lassen zwischen letzteren in beschränktem Urnfang auch ein gewisses axiales Bewegungsspiel zu. Da bei dieser bekannten Ausführungsform die Gummiringe jedoch auf Druck vorgespannt sind und Felge und Nabe in ihrer mittleren Stellung sich in einer labilen Gleichgewichtslage befinden, können von solchen Rädern radiale Fahrstöße nur in beschränktem Umfang aufgenommen werden.Finally, spring-loaded aircraft wheels are also known, where rubber rings are roughly square between the discs attached to the rim and the hub Cross-section are provided, which is the only connection between the discs of the hub with that of the Represent rim. These rubber rings not only allow radial mobility of the rim with respect to it the hub, but also allow a certain amount of axial movement between the latter to a limited extent to. Since in this known embodiment, however, the rubber rings are prestressed under pressure and the rim and hub are in an unstable equilibrium position in their middle position radial driving jolts are only absorbed to a limited extent by such wheels.

Der Erfindung liegt die Aufgabe zugrunde, ein luftbereiftes Fahrzeugrad mit zusätzlicher Federung durch zwischen Felge und Nabe angeordnete elastische Ringe aus Gummi od. dgl. zu schaffen, das die den bekannten Rädern anhaftenden Mängel nicht aufweist und das trotz einer hinreichend nachgiebigen Verbindung zwischen Felge und Nabe auch in axialer Richtung dennoch eine sichere, auch bereits bei geringeren radialen Verschiebungen der Felge gegenüber der Nabe wirksam werdende Abfederung der elastisch miteinander verbundenen Radteile gewährleistet.The invention is based on the object of a vehicle wheel with pneumatic tires with additional suspension by arranged between the rim and the hub elastic rings made of rubber od. The like. To create the known Wheels does not have any defects, despite a sufficiently flexible connection between the rim and the hub, even in the axial direction, a safe one, even with smaller ones radial displacements of the rim relative to the hub effective cushioning of the elastic with each other connected wheel parts guaranteed.

Das wird, ausgehend von einem Fahrzeug der eingangs beschriebenen Art, erfindungsgemäß durch die Vereinigung der folgenden, jeweils für sich bekannten Merkmale erreicht:Based on a vehicle of the type described at the outset, this is carried out according to the invention by the Combination of the following, each known for itself, achieved:

Due to the sole connection between the rim

und Nabe sowohl in axialer als auch in radialer Richtung gewährleistenden, auf Zug vorgespannten Gummiringe ist sichergestellt, daß die miteinander und besonders auch in axialer Richtung ausreichend nachgiebig verbundenen Teile bereits in ihrer Mittellage verhältnismäßig hart gefedert und so den im Fahrbetrieb auftretenden Beanspruchungen gewachsen sind und die Fahreigenschaften des Fahrzeuges beträchtlich verbessern.and hub both in the axial and in the radial direction ensuring, tension-pretensioned rubber rings it is ensured that they are sufficiently flexible with one another and especially in the axial direction connected parts already sprung relatively hard in their central position and so in driving operation are able to cope with the stresses that occur and the driving characteristics of the vehicle are considerable to enhance.

Eine besonders vorteilhafte Ausführungsform ergibt sich dann, wenn in an sich bekannter Weise die zu beiden Seiten eines an der Nabe vorgesehenen radialen Flansches befestigten Scheiben außerhalb der Befestigungsstelle aus der Flanschebene heraus gekröpft sind, mit ihren äußeren Ringteilen parallel zur Flanschebene verlaufen und an den inneren Seiten der zueinander parallelen Ringteile die Gummiringe trägen.A particularly advantageous embodiment is obtained when the to in a known manner both sides of a radial flange provided on the hub, fastened disks outside the fastening point are cranked out of the flange plane, with their outer ring parts parallel to the flange plane run and wear the rubber rings on the inner sides of the mutually parallel ring parts.

Hierbei kann ein einziger Gummiring verwendet werden, der sich von einer Nabenscheibe zur anderen erstreckt und an den der Felgenträger außen anvulkanisiert ist. Vorteilhafter ist es jedoch, in an sich bekannter Weise beiderseits der Längsmittelebene des Rades je einen Gummiring vorzusehen und die einander zugekehrten Flächen der Gummiringe an je eine oder an einer gemeinsamen, mit der Felge verbundenen Scheibe anzuvulkanisieren.A single rubber ring can be used here, which extends from one hub disk to the other extends and to which the rim carrier is vulcanized on the outside. However, it is more advantageous in and of itself It is known to provide a rubber ring on both sides of the longitudinal center plane of the wheel and each other facing surfaces of the rubber rings on each one or on a common one connected to the rim Vulcanize the disc.

Claims

1 050 67Ö The arrangement can also be reversed in such a way that the outwardly cranked rubber rings are attached to the rim between receiving disks and the rubber ring or rings are connected to one or more disks extending from the hub. It is also possible to provide the disk parts located between the rubber rings with bores in order to achieve a confluence and better adhesion of the rubber. It has been shown that with such an arrangement of rubber elements that are more or less strongly tensioned, a perfect natural suspension of the wheel is achieved without impairing its lateral stability. The wheel remains exactly centered, with the exception of small, harmless lateral deflections that do not affect the vehicle's spooky behavior when cornering. The durability of the rubber elements also meets the requirements. To secure the vehicle in the event that an already aged rubber ring tears under exceptional stress, according to the invention, in a manner known per se, the parallel ring parts of the outwardly cranked disks outside the flange, which are directly connected to the hub flange, enclose an annular air space The inner circumference of the rim disks is provided with a protrusion that protrudes inwards beyond the inner circumference of the rubber ring. If a rubber ring tears, this projection - or if there are several rim disks, the projections of all disks - falls into the space and maintains the lateral stability of the wheel. The bias of the rubber elements can be achieved in various ways, for. B. in that two rim disks are provided and each is connected near its inner circumference to the rubber ring attached to the associated hub disk. When the two rim disks are screwed together, the desired 'axial tensile prestressing of the rubber rings is obtained. In the drawing, the invention is illustrated using an exemplary embodiment. The hub 1 carries a radial flange 2 to which the two disks 3 and 4 are attached. With its split, radially directed flanges 6 and 7, the rim carrier 5 is connected to the disks 3 and 4 via the rubber bodies 8 and 9, respectively. The rubber body 8 is vulcanized together with the disks 3 and 6, the rubber body 9 with the disks 4 and 7. According to the direction of the arrow, the rubber bodies 8 and 9 are tensioned. The inner part 10 of the radial flanges 6 and 7 can engage in the annular gap 11 between the disks 3 and 4 if a rubber element breaks. Ρλ Τ Κ Νΐ Λ NSP K OC.Il E:
