Abstract

The spiked bolts have their bases incorporated in a support belt which transmit radial forces uniformly to the tyre tube or main air chamber of the tyre. The additional air chambers are located between the bolts such that when they are inflated the spikes are retracted below the surface of the tread but when they are deflated the spikes extend above the tread surface. An auxiliary air-chamber valve is incorporated in the side of the tyre. The three constructional elements - tyre wall, bolts and air chambers - can be assembled as separate units or integrated so that they are constructionally inseparable in which case they form a tubeless tyre.

Description

Blatt έ Patentbeschreibang.Sheet έ patent description.

Ein Winterreifen, der bei direktem Bedarf in einen Spikereifen verwandelt werden kann. A winter tire that can be converted into a studded tire when needed .

Anwendungsgebiet; Geeignet für LKW und PKW als Winterbereifung. Field of use; Suitable for trucks and cars as winter tires.

Zweck; Gemäß der Erfindung sind die Vorteile eines herkömmlichen Spikereifen durch Anwendung erst bei direktem Bedarf mit den Vorteilen des Fahrens von Winterreifen verbunden. Die Benützung der Spikes ist auf Straßen beschränkt, die den Sinn von Spikes rechtfertigen. ■ Stand der Technik: Es ist bekannt, daß es beim derzeitigen Stand der Technik nur möglich ist entweder Spikereifen oder ÜTormal-Winterreifen zu fahren. Ein Umrüsten muß durch Montage vorgenommen werden. Purpose; According to the invention, the advantages of a conventional studded tire are combined with the advantages of driving winter tires by using them only when there is a direct need. The use of spikes is restricted to streets that justify the use of spikes. State of the art: It is known that with the current state of the art it is only possible to drive either studded tires or normal winter tires. Retrofitting must be carried out by assembly.

Kritik des Standes der Technik; Dem. Wesen einer ausreichenden Winterbereifung liegt es inne, für überraschende oder örtlich begrenzte schlechte Straßenverhältnisse gerüstet zu sein. Die meisten Autofahrer fahren deshalb den ganzen Winter über Spikereifen, ungeachtet des tatsächlichen Zustandes der gerade bewahrenden Straße. Dabei kommen für Autofahrer und Staat die Bachteile der Spikereifen zumTragen: schlechtere Bremswirkung, hohe Straßenschäden usw. Aufgabe der Erfindung; Die Erfindung hat die Aufgabe, die Uachteile beider derieitiger Winterbereifungsmöglichkeiten weitgehendst abzuschaffen. Sie bietet die Möglichkeit, einen Winterreifen angesichts einer vereisten Straße durch geringen technischen Aufwand an Ort und Stelle in einen Spikereifen zu verwandeln; oder vor dem Einfahren in ein schnee und eisfreies Straßennetz die dann unnützen und schädlichem Spikes an einer Luftzapfstelle einzuziehen. Die Erfindung hat auch die Aufgabe, dem Staat die vernünftige Grundlage für ein generelles Verbot von Spikesreifen auf allen Bundesautobahnen zu schaffen, Criticism of the state of the art; It is inherent in the essence of adequate winter tires to be prepared for surprising or localized poor road conditions. Most motorists therefore drive studded tires all winter, regardless of the actual condition of the road being kept. The brook parts of the studded tires come into play for motorists and the state: poorer braking effect, high road damage, etc. Object of the invention; The invention has the task of largely abolishing the disadvantages of both such winter tire options. It offers the possibility of turning a winter tire into a studded tire with little technical effort in the face of an icy road; or before entering a snow and ice-free road network, pulling in the useless and harmful spikes at an air tap. The invention also has the task of providing the state with a reasonable basis for a general ban on studded tires on all federal motorways,

Die Lösung der Aufgabe; Diese Aufgabe wird erfiindungsgemäß dadurch, gelöst, daß mit dem Einbau eines zusätzlichen Luftkammersystems ( 9 ) in den Reifen eine Anordnung von Spikebolzen ( 2 ),· durch Ein- bzw. Auslassen von Druckluft, in JPührungsbohrungen öadial bewegbar ist. Weitere Ausgestaltung der Erfindung: Um einen solchen Reifen erfindungsgemäß zu bauen, sind speziell gefertigte Baugruppen nötig: The solution to the task ; This object is achieved according to the invention in that with the installation of an additional air chamber system (9) in the tire, an arrangement of spike bolts (2) can be moved axially in guide bores by letting in or out compressed air. Further embodiment of the invention : In order to build such a tire according to the invention, specially manufactured assemblies are required:

a) Reifenmantel, mit durchbrochener Stützwand ( bisher z.B. leinwand) ( 8 )a) Tire casing, with a perforated support wall (previously e.g. canvas) (8)

b) Spikebolzen ( 2 ) auf einem Trägergürtel ( 5 ) derart, daß sich radiale Kräfte gleichmäßig auf den Schlauch ( 6 ) bzw, auf die luftkammer des Reifens übertragen,b) spike bolts (2) on a carrier belt (5) in such a way that that radial forces are evenly transferred to the tube (6) or to the air chamber of the tire,

c) Zusätzliche Luftkammern derart, daß sie beim Umgebungsdruck ein Luftvolumen das von Hull wenig verschieden ist, besitzen und die sich beim Eiusteuem von Druckluft nach innen so ausdehnen, daß die Spikebolzen eingezogen werden.c) Additional air chambers such that they are at ambient pressure have an air volume which is little different from Hull and which is at the level of compressed air expand inwards so that the spike bolts are drawn in.

Diese drei Baugruppen können voneinander getrennt zusammengebaut seirt; sie können aber auch, miteinander verbunden (integriert) sein, derart, daß sie nur noch als !Funktionszonsn bestehen und baulich uniertrennbar sind. In letzterem lall ist die Erfindung als schlauchloser Reifen gegeben.These three assemblies can be assembled separately from one another seirt; but they can also be connected to one another be (integrated) in such a way that they only function as! exist and are structurally inseparable. In the latter lall is the invention as a tubeless tire given.

Erzielbare Torteile: Verringerung der alljährlich durch Spikesreifen hervorgerufenem Straßenschäden, Sicherheit auf eisigen Straßen; kürzerer Bremsweg auf freien Straßen usw, Achievable goal parts: Reduction of road damage annually caused by studded tires, safety on icy roads; shorter braking distance on open roads etc,
