Pneumatisches GummischeibenradPneumatic rubber disc wheel

Patentiert im Deutschen Reiche vom 4. Oktober 1932 abPatented in the German Empire on October 4, 1932

Bei der Entwicklung der Kraftfahrzeugbereifung wurde angestrebt, das Fahrzeug auf einem immer weicheren Luftkissen abzufedern. Diese Richtung führte schließlich vom einfachen Ballonreifen zum Überballonreifen, der auf Grund seines größtmöglichen Luftraumes und somit auch niedrigsten Innendruck eine weitgehende stoßfangende Wirkung auszuüben vermag,
to Infolge dieser Eigenschaften ist dem Überballonreifen das größtmögliche Luftkissen zu eigen, welches kleinere Hindernisse, die auf der Straße vorhanden sind, in sich aufnimmt, wodurch der Überballonreifen sich der Straßenoberfläche vollkommen anschmiegt.During the development of vehicle tires, the aim was to cushion the vehicle on an increasingly soft air cushion. This direction ultimately led from a simple balloon tire to an over-balloon tire, which is able to exert a largely shock-absorbing effect due to its largest possible air space and thus also the lowest internal pressure.
As a result of these properties, the balloon tire has the largest possible air cushion, which takes up smaller obstacles that are present on the road, so that the balloon tire hugs the road surface completely.

Das aufpumpbare Gummischeibenrad stellt die letzte Entwicklungsetappe des Überballonreifens dar, wodurch auf Grund des letztmöglichen größten Luftkissens ein dementsprechend großes Schluckvermögen erzeugt wird.The inflatable rubber disc wheel represents the final stage in the development of the balloon tire represents, whereby due to the last possible largest air cushion a corresponding large swallowing capacity is generated.

Der größte Teil von dem Nachgiebigkeitsvermögen des Luftkissens wird indessen beim Überballonreifen bzw. Überballonrad durch die ballonartige breite Formgestaltung, welche sich beim Aufpumpen zwangsläufig ergibt, aufgezehrt.Most of the resilience of the air cushion is, however, in the Over balloon tire or over balloon wheel due to the balloon-like wide shape, which inevitably results when pumping up, consumed.

Da also die Ausdehnungsmöglichkeit durch die ballonartige Formgestaltung zum größten Teil weggenommen ist, bleibt wenig an Dehnfähigkeit übrig, so daß eine größere stoßfangende Wirkung ausgeschlossen ist.So there the expansion possibility through the balloon-like shape to the greatest Part is taken away, there is little elasticity left, so that a larger impact-absorbing Effect is excluded.

Die Ausführungsbeispiele vorliegender Erfindung zeigen ein pneumatisches Rad, bei dem die kleineren Hindernisse, welche dieThe embodiments of the present invention show a pneumatic wheel which the smaller obstacles the

Straße bietet, von dem eigentlichen äußeren Laufreifen verschluckt bzw. aufgeschluckt werden, die schädliche Wirkung der größeren Hindernisse dagegen durch eine zweckmäßige Ausbildung des Reifens ausgeschaltet wird, so daß ein Fahrzeug, welches mit solchen pneumatischen Rädern ausgerüstet ist, dieselben Fahreigenschaften besitzt, wie sie einem Fahrzeug mit achslos aufgehängten einzelgefederten Rädern, den sogenannten Schwingachsen, entsprechen.Road offers, swallowed or swallowed up by the actual outer tire the harmful effect of the larger obstacles, on the other hand, by a purposeful one Training of the tire is turned off, so that a vehicle which with such pneumatic wheels is equipped, has the same driving characteristics as it a vehicle with axially suspended single-sprung wheels, the so-called Oscillating axes correspond.

Abb. 5 eine Seitenansicht nach Abb. 4.Fig. 5 is a side view according to Fig. 4.

Das Rad besteht aus einem scheibenförmigen hohlen Gummikörper D, der durch ein Ventil D¹ auf einen durch die Belastung des Fahrzeuges bedingten Innendruck aufgepumpt werden kann. Zwecks leichter Montage des Gummirades auf dessen Nabe besteht dieselbe aus zwei ineinander verschiebbaren oder zusammenschraubbaren Lager-The wheel consists of a disc-shaped hollow rubber body D, which can be inflated through a valve D ¹ to an internal pressure caused by the load on the vehicle. For the purpose of easy mounting of the rubber wheel on its hub, it consists of two bearings that can be slid into one another or screwed together.

Claims

sleeves C and C ^l _{ which are

■ screwable oil lock pins C ² are secured against loosening.

The wheel hub is fastened in a suitable way on the axle A and can be secured against loosening by a screw cap B.

\ will.

The drive elements and the brake drums can also be attached to the wheel hub itself be.

In order to prevent the wheel from assuming the wide balloon-like shape required to overcome a larger obstacle while inflating, a ring of spring pulls / or rubber bands L is arranged in the interior of the wheel body D , which, due to their stored elasticity, can be used if necessary regulate the required expansion of the tires.

An excessive tensile expansion of the spring balances 7 or elastic cords L _1, which would have an adverse effect on the safety of the wheel, is prevented by the wave-shaped or arched tension limiting cords K and M.

The spring or elastic cords / and L and the tension limiting cords K and M are on metal tires H ,. which on the two flat

- Walls of the rubber body walls D are embedded in the material, anchored.

The transmission of the impact effect to the lower wheel half takes place through the rim-like steel sleeve E, " which is stretched around the running surface of the wheel body D , whereby the running surface is given a dimensionally stable state in contrast to the shape-changing side walls of the wheel body D.

As a result of the circumference limitation thus achieved, the wheel diameter and thus also the wheel circumference always remain the same, so that the change in shape of the two side walls of the wheel body D takes place within the wheel body space delimited by the steel sleeve E.

In order to achieve a firm hold of the steel sleeve E on the circumference of the wheel body D , it is provided with grooves or cams E ¹ , into which the rubber is pressed when it is inflated.

The steel sleeve E is expediently given a somewhat elastic state, which, however, must be dimensioned so small that the operation of the entire wheel is not impaired.

If a vehicle that is equipped with these pneumatic wheels is used on a roadway on which there are no minor bumps, the steel sleeve E can run directly on the roadway. In the event that it is a vehicle equipped with these pneumatic wheels, which is used on a roadway where small bumps have to be overcome, the steel sleeve E is covered with a replaceable solid rubber overlay F , which helps to swallow small obstacles can be.

The solid rubber blanket is secured against slipping off the steel sleeve E, that grooves or cams E ² of the steel collar E with respective profiles G of a protector F are engaged.

Metal or other suitable inserts N _} which can be interwoven by known methods can also be incorporated into the wheel body as well as into the tread, which both give the whole a greater stability and make it more difficult for injurious objects to penetrate.

With the help of the rigid steel sleeve E , the impact effect generated by the attack of the obstacle is transmitted and distributed to the lower half of the wheel from W ¹ to W ² and IV ^s (Fig. 5).

Due to the great flexibility that is inherent in the two side walls of the wheel body D due to the oversized air vacuum cushion, the dynamic oscillating movements of the steel sleeve E are transmitted to the spring balances J or elastic bands L with their help.
