Abstract
Tubeless tyres sitting in the wheel rim are fitted with two flexible hoses of rubber or plastic material, held by adhesive tape and able to withstand an internal and external pressure of 6 bar. Radial spikes are normally retracted inside the tyre by springs. In case of ice on the road, an internal hose is inflated to push the spikes outside. ADVANTAGE - This prevents unnecessary damage to the road surface.
Description
BESCHREIBUNG
Diese mobile Ausführung hat den grossen Vorteil gegen über immobilen Spikes, indem die Strassen nicht in unnötiger Weise durch Spikes strapaziert werden.
In eingezogenem Zustand können in der Schweiz auf den Autobahnen und im Ausland auch bei Spikes-Verbot gefahren werden, aber bei Schneefall oder bei Glatteis stehen die Spikes zu jeder Zeit zur Verfügung. Die Bremswege mit eingezogenen Spikes entsprechen auch den normalen Bremswerten der Reifen ohne Spikes.
Die Figur 1 zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes, der im folgenden erläutert wird:
Der Autoreifen 2 in der Felge 1 ist beidseitig je mit einem flexiblen Rohr 6 versehen. Diese flexiblen Rohre 6 können bei der Reifenherstellung oder nachträglich mittels eines Haltebandes 3 eingebaut werden und müssen gegen Aussenwie Innendruck von ca. 6 Bar widerstehen können. Aus jedem flexiblen Rohr 6 werden die radial eingebauten Spikes 8 bewegt. Wenn in dem flexiblen Rohr 6 Druck erzeugt wird durch Luft, andere Gase oder durch Flüssigkeit, werden durch Wirkverbindung die Spikes 8 hinausgefahren. Bei Ablassen des Druckes versinken die Spikes 8 unter die Lauffläche 4 des Reifens 2. Die Spikes 8 sind im Normalfall unter die Lauffläche 4 gezogen. Dies kann durch Einbau von Federn 7 oder magnetisch oder auch durch Vakuum erreicht werden.
Der Druck in dem flexiblen Rohr 6 kann durch einen aufpumpbaren Schlauch 5 erzeugt werden. Bei luftdichtem Einbau des flexiblen Rohres 6 kann auch ohne Schlauch 5 der Druck erzeugt werden.
Die flexiblen Rohre 6 können aus armiertem Gummi oder aus Kunststoff erstellt werden. Die Spikes 8 können aus Metall oder auch auch Kunststoff hergestellt werden. Die Spikes 8 sind verschieblich in Leithülsen 9 geführt.
Der Reifen selbst kann mit gewöhnlichem Schlauch aufgepumpt werden oder bei luftdichter Ausführung kann auch schlauchlos aufgepumpt werden.
Der Druck für das flexible Rohr zum Ausfahren der Spikes kann bei Notfall unterwegs aus dem Reifendruck abgezapft werden und bei der nächsten Tankstelle der Reifendruck wieder nachgepumpt werden oder kann auch mit tragbarem Kleinkompressor mit Stromanschluss im Zigarrenanzünder oder aus tragbaren Luftdruckflaschen, erreicht werden. Dieser Druck in dem flexiblen Rohr und in dem Reifen variiert und wird für jeden Reifentyp angegeben.
Bei einem Ausbau mit elektronischer Steuerung können die Spikes auch aus dem Wageninneren ferngesteuert werden und kann auch durch Anschluss an einem Bordcomputer bei ungenügendem Bremswiderstand die Fernsteuerung automatisch betätigt werden.
DESCRIPTION
This mobile version has the great advantage over immobile spikes in that the streets are not unnecessarily stressed by spikes.
In the retracted state, you can drive on the motorways in Switzerland and abroad, even if spikes are prohibited, but the spikes are available at all times in the event of snow or black ice. The braking distances with the spikes retracted also correspond to the normal braking values of the tires without spikes.
FIG. 1 shows an exemplary embodiment of the subject matter of the invention, which is explained in the following:
The car tire 2 in the rim 1 is provided on both sides with a flexible tube 6. These flexible tubes 6 can be installed during tire manufacture or subsequently by means of a holding strap 3 and must be able to withstand external and internal pressures of approximately 6 bar. The radially installed spikes 8 are moved from each flexible tube 6. If pressure is generated in the flexible tube 6 by air, other gases or by liquid, the spikes 8 are moved out by an operative connection. When the pressure is released, the spikes 8 sink under the tread 4 of the tire 2. The spikes 8 are normally pulled under the tread 4. This can be achieved by installing springs 7 or magnetically or by vacuum.
The pressure in the flexible tube 6 can be generated by an inflatable tube 5. If the flexible tube 6 is installed in an airtight manner, the pressure can also be generated without a hose 5.
The flexible tubes 6 can be made of reinforced rubber or plastic. The spikes 8 can be made of metal or plastic. The spikes 8 are slidably guided in guide sleeves 9.
The tire itself can be inflated with an ordinary tube or with an airtight version it can also be inflated tubeless.
In an emergency, the pressure for the flexible tube to extend the spikes can be tapped from the tire pressure on the way and the tire pressure can be pumped up again at the next gas station or can also be achieved with a portable small compressor with a power connection in the cigar lighter or from portable air pressure bottles. This pressure in the flexible tube and in the tire varies and is given for each type of tire.
In the case of an expansion with electronic control, the spikes can also be remotely controlled from the inside of the car and the remote control can also be operated automatically by connecting to an on-board computer if there is insufficient braking resistance.
