Kolbenpumpenkompressor mit Druckbehälter für FahrzeugePiston pump compressor with pressure vessel for vehicles
Die Erfindung betrifft einen Kolbenpumpenkorapressor mit Druckbehälter für Fahrzeuge.The invention relates to a piston pump compressor with pressure vessel for vehicles.
Erfindungsgemäß ist vorgesehen, daß der Kolbenpumpenkompressor in einen Stoßdämpfer des Fahrzeugs integriert ist, derart, daß die Stoßdämpferhubbewegung gleichzeitig die Hubbewegung des Kolbenpumpenkompressors ist. Die bei Fahrt eines Fahrzeuges zwischen Aufbau und Radachse auftretenden Federschwingungen können auf diese Weise in vorteilhafter Weise zur Erzeugung von Druckluft genutzt werden, die dann beispielsweise zum Aufpumpen von Luftreifen des Fahrzeuges verwendet werden kann.According to the invention, the piston pump compressor is integrated into a shock absorber of the vehicle in such a way that the shock absorber stroke movement is simultaneously the stroke movement of the piston pump compressor. The spring vibrations that occur between the body and the wheel axle when a vehicle is driving can thus be used advantageously to generate compressed air, which can then be used, for example, to inflate the vehicle's pneumatic tires.
Besonders vorteilhaft ist der Einsatz des Gegenstandes der Erfindung an einem Zweirad, und zwar derart, daß der zur Druckerzeugung vorgesehene Kolbenpumpenkompressor unterhalb des Sattels angebracht ist. Hierzu ist in zweckmäßiger Ausgestaltung der Erfindung vorgesehen, daß bei einer Anordnung an einem Fahrzeug mit einem an einem Sattelstützrohr des Rahmens angebrachten Sattel das Sattelstützrohr einen Hohlzylinder aufweist, und der Sattel an einem entgegen einer Vorspannkraft (z.B. Feder) verschiebbar in dem Hohlzylinder geführten, einen Druckbehälter bildenden Hohlkolben angebracht ist, und der Boden des HohlZylinders und der Boden des Hohlkolbens Ventile aufweisen. Die durch die Gewichtskraft der auf demThe use of the subject matter of the invention on a two-wheeler is particularly advantageous, in such a way that the piston pump compressor intended for generating pressure is mounted below the saddle. For this purpose, in an expedient embodiment of the invention, when arranged on a vehicle with a saddle attached to a saddle support tube of the frame, the saddle support tube has a hollow cylinder and the saddle is attached to a hollow piston that forms a pressure vessel and is guided in the hollow cylinder so as to be displaceable against a preload force (e.g. spring), and the bottom of the hollow cylinder and the bottom of the hollow piston have valves. The pressure created by the weight of the piston on the
Sattel sitzenden Person infolge der zwangsläufig auftretenden Fahrbahnunebenheiten erzeugten Schwingungen führen zu einer Relativbewegung des Hohlkolbens in dem Hohlzylinder des Sattelstützrohres. Bei einer Aufwärtsbewegung des Hohlkolbens öffnet sich das Ventil im Boden des Hohlzylinders. Bei einer Abwärtsbewegung schließt sich das Ventil im Boden des Hohlzylinders, und das Ventil im Boden des Hohlkolbens geht in Durchlaßstellung. Durch die Volumenverkleinerung bei der Abwärtsbewegung wird der Druck im Inneren des Hohlzylinders und des Hohlkolbens erhöht. Bei einer erneuten Aufwärtsbewegung des Hohlkolbens wird durch diesen erhöhten Druck das Ventil im Boden des Hohlkolbens in Schließstellung gehalten. Die durch das dann in Öffnungsstellung befindliche Ventil im Boden des Hohlkolbens nachströmende Luft führt dann bei der nachfolgenden Abwärtsbewegung zu einer weiteren Druckerhöhung, usw.. Es versteht sich, daß natürlich ein Überdruckventil vorgesehen ist, und darüber hinaus eine Entnahmeeinrichtung für die erzeugte Druckluft. Die Entnahmeeinrichtung kann beispielsweise als Druckschlauch mit angeschlossenem Füllventil ausgebildet sein, welcher in eine Entnahmeöffnung einschraubbar ist.The vibrations generated by the person sitting on the saddle as a result of the inevitable unevenness in the road lead to a relative movement of the hollow piston in the hollow cylinder of the seat support tube. When the hollow piston moves upwards, the valve in the base of the hollow cylinder opens. When it moves downwards, the valve in the base of the hollow cylinder closes and the valve in the base of the hollow piston goes into the open position. The reduction in volume during the downward movement increases the pressure inside the hollow cylinder and the hollow piston. When the hollow piston moves upwards again, this increased pressure keeps the valve in the base of the hollow piston in the closed position. The air flowing through the valve in the base of the hollow piston, which is then in the open position, then leads to a further increase in pressure during the subsequent downward movement, etc. It goes without saying that a pressure relief valve is of course provided, as well as a removal device for the compressed air generated. The extraction device can, for example, be designed as a pressure hose with a connected filling valve, which can be screwed into an extraction opening.
Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Die Figur zeigt schematisch die erfindungsgemäße Ausgestaltung eines Sattelstützrohres eines Zweiradfahrzeuges, wobei der Sattel selbst nicht dargestellt ist.The invention is explained in more detail below with reference to the drawing. The figure shows schematically the inventive design of a seat support tube of a two-wheeled vehicle, where the saddle itself is not shown.
In der Zeichnung ist schematisch ein Tretkurbellager 1 eines Fahrrades dargestellt. Von dem Tretkurbellager 1 nach oben erstreckt sich ein insgesamt mit 2 bezeichnetes Sattelstützrohr, welches einen Teil eines (nicht dargestellten) Fahrradrahmens bildet. Am oberen Ende 3 des Sattelstützrohres 2 ist ein (nicht dargestellter) Sattel anbringbar.The drawing shows a schematic representation of a pedal crank bearing 1 of a bicycle. A seat post tube, designated overall by 2, extends upwards from the pedal crank bearing 1 and forms part of a bicycle frame (not shown). A saddle (not shown) can be attached to the upper end 3 of the seat post tube 2.
Das Sattelstützrohr 2 weist in einer mit 4 bezeichneten Sattelstange einen nach oben offenen Hohlzylinder 5 auf, der fest mit der Sattelstange 4 verbunden ist. Im Boden 6 desThe seat post tube 2 has a seat post marked 4 with an upwardly open hollow cylinder 5 which is firmly connected to the seat post 4. In the bottom 6 of the
Hohlzylinders ist ein schematisch dargestelltes Ventil 7 mit einem Ventilkörper 8 vorgesehen. Der Hohlzylinder 5 weist in seinem oberen Bereich Axialnuten 9, 10 auf, in denen Führungsteile 11, 12 eines insgesamt mit 13 bezeichneten Hohlkolbens auf- und abbewegbar geführt sind. Die Sattelstange 4 ist in ihrem oberen Bereich verbreitert und endet in einem Federteller 14. Der Hohlkolben 13 weist einen Federteller 15 auf. Zwischen Federteller 14 und Federteller 15 befindet sich eine Feder 16. Der Hohlkolben 13 weist in seinem Boden 17 ein Ventil 18 mit einem Ventilkörper 19 auf. In der oberen Begrenzung des Hohlkolbens 13 befindet sich eine Entnahmeöffnung 20, in die ein Druckschlauch mit am Ende angeordnetem Füllventil eingeschraubt werden kann. Der somit nach außen abgeschlossene Innenraum 21 bildet einen Druckbehälter. Ein weiterhin vorgesehenes Überdruckventil, welches bei Überschreiten eines vorgesehenen Maximaldruckes in Öffnungsstellung geht, ist nicht dargestellt. Am oberen Ende des Hohlkolbens 13 wird der (nicht dargestellte) Sattel des Fahrrades befestigt.A schematically illustrated valve 7 with a valve body 8 is provided in the hollow cylinder 5. The hollow cylinder 5 has axial grooves 9, 10 in its upper area, in which guide parts 11, 12 of a hollow piston, designated overall by 13, are guided so that they can move up and down. The saddle rod 4 is widened in its upper area and ends in a spring plate 14. The hollow piston 13 has a spring plate 15. Between the spring plate 14 and the spring plate 15 there is a spring 16. The hollow piston 13 has a valve 18 with a valve body 19 in its base 17. In the upper limit of the hollow piston 13 there is a removal opening 20 into which a pressure hose with a filling valve arranged at the end can be screwed. The interior 21, which is thus closed off from the outside, forms a pressure vessel. A further pressure relief valve, which opens when a specified maximum pressure is exceeded, is not shown. The saddle of the bicycle (not shown) is attached to the upper end of the hollow piston 13.
Die Funktion der Vorrichtung ist wie folgt:The function of the device is as follows:
Es sei angenommen, daß der Hohlkolben 13 in dem Hohlzylinder 5 infolge des Gewichts des auf dem Sattel sitzenden Fahrers die in der Zeichnung dargestellte Position einnimmt, in welcher sowohl eine Hubbewegung nach unten als auch nach oben möglich ist. Bei einer Bewegung des Hubkolbens 13 nach oben geht das Ventil 7 in Öffnungsstellung. Bei einer anschließenden Hubbewegung nach unten geht das Ventil 7 in Schließstellung. Da sich bei einer Abwärtsbewegung der Gesamtraum oberhalb des Ventils 7 verkleinert, tritt eine Druckerhöhung ein. Bei einer anschließenden Bewegung des Hubkolbens 13 nach oben bleibt diese Druckerhöhung im Inneren des Hohlkolbens 13 erhalten, da das Ventil 18 zwangsläufig in Schließstellung ist. Der Druck in dem Hohlkolben 13 wird bei einer weiteren Hubbewegung erhöht, bis der durch das Druckbegrenzungsventil bestimmte Maximaldruck erreicht ist.It is assumed that the hollow piston 13 in the hollow cylinder 5, due to the weight of the rider sitting on the saddle, assumes the position shown in the drawing, in which both a downward and upward lifting movement is possible. When the lifting piston 13 moves upwards, the valve 7 goes into the open position. When the lifting piston 13 then moves downwards, the valve 7 goes into the closed position. Since the total space above the valve 7 decreases during a downward movement, a pressure increase occurs. When the lifting piston 13 then moves upwards, this pressure increase is maintained inside the hollow piston 13, since the valve 18 is necessarily in the closed position. The pressure in the hollow piston 13 is increased during a further lifting movement until the maximum pressure determined by the pressure limiting valve is reached.
Auf diese Weise steht bereits nach einer kurzen Fahrt ein Luftdruck zur Verfügung, mit welchem die für die Bereifung erforderlichen Drücke ohne weiteres aufgebracht werden können. In this way, after just a short drive, an air pressure is available with which the pressures required for the tires can be easily applied.
