Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Rollenprüfstand nach der Gattung des Hauptanspruchs. Bei einem derartigen bekannten Rollenprüfstand ist der Hub zylinder an ein Druckluftnetz angeschlossen. Das hat den Nachteil, daß für den Betrieb des Rollenprüfstands ein Druckluftnetz vorhanden sein muß, wodurch die Einrichtung sehr verteuert wird.The invention is based on a roller dynamometer of the type of the main claim. In such a known roller test stand, the stroke is a cylinder connected to a compressed air network. This has the disadvantage that for the operation of the Roller dynamometer a compressed air network must be available, which makes the facility very becomes more expensive.
Vorteile der Erfindung Der erfindungsgemäße Rollenprüfstand mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die durch den Hubzylinder betätigte Hebe- bzw. Brems- oder Blokkiervorrichtung unabhängig von Anschlüssen an ein Druckluftnetz oder ähnliches ist. Dadurch wird der Rollenprüfstand sehr flexibel in seiner Anwendungsmöglichkeit und auch billig.Advantages of the Invention The roller dynamometer according to the invention with the characterizing features of the main claim has the advantage that the Lifting or braking or blocking device actuated by the lifting cylinder independently of connections to a compressed air network or the like. This becomes the roller dynamometer very flexible in its application possibilities and also cheap.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Merkmale möglich.The measures listed in the subclaims are advantageous Further developments and improvements to the features specified in the main claim are possible.
Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.Drawing An embodiment of the invention is shown in the drawing and explained in more detail in the following description.
Die Zeichnung zeigt eine schematische Darstellung des Rollenprüfstands.The drawing shows a schematic representation of the roller dynamometer.
Beschreibung der Erfindung Der Rollenprüfstand besteht im wesentlichen aus zwei Laufrollen 10 und 11, die durch das oder die Räder 12 des zu testenden Fahrzeugs angetrieben werden. Zum Heben des Fahrzeugrads 12 und/oder zum Blockieren der Laufrollen 10, 11 dient ein durch Druckluft beaufschlagter einseitig wirkender Hub zylinder 14, dessen Kolbenstange 15 ortsfest angeordnet ist In den Raum 16 oberhalb des mit der Kolbenstange 15 fest verbundenen Kolbens 17 mündet eine Leitung 18, die zur einem 2-Wegeventil 19 führt.Description of the Invention The roller dynamometer essentially consists of two rollers 10 and 11, which are driven by the wheel or wheels 12 of the to be tested Vehicle are driven. For lifting the vehicle wheel 12 and / or to block the rollers 10, 11 a one-sided acted upon by compressed air is used Acting stroke cylinder 14, the piston rod 15 is fixedly arranged in the Space 16 opens above the piston 17 firmly connected to the piston rod 15 a line 18 which leads to a 2-way valve 19.
Auf der Laufrolle 11 ist eine Riemenscheibe 20 angeordnet, die über einen Riemen 21 eine Riemenscheibe 22 antreibt, die zum Antrieb eines Luftpressers 23 dient.On the roller 11, a pulley 20 is arranged, which over a belt 21 drives a pulley 22 which drives an air compressor 23 serves.
Wenn das Fahrzeugrad 12 die Laufrollen 10, 11 antreibt, wird über den Riementrieb auch der Luftpresser angetrieben. Die von ihm erzeugte Druckluft gelangt über eine Leitung 24 zu einem Druckbehälter 25, von dem eine Leitung 26 zum Ventil 19 führt.When the vehicle wheel 12 drives the rollers 10, 11, over the belt drive also driven the air compressor. The compressed air it generates reaches a pressure vessel 25 via a line 24, from which a line 26 leads to valve 19.
Soll das Fahrzeugrad 12 angehoben und/oder die Laufrollen 10, 11 blockiert werden, so wird das Ventil 19 in Durchflußstellung gebracht worauf Druckluft aus dem Druckbehälter 25 über die Leitung 18 in den Raum 16 des Hubzylinder fließt. Dieser legt sich darauf mit seiner Oberfläche an das Fahrzeugrad und/oder an die Laufrollen, worauf diese blockiert bzw. das Fahrzeugrad angehoben werden kann.If the vehicle wheel 12 is to be raised and / or the rollers 10, 11 are blocked are, the valve 19 is brought into the flow position, whereupon compressed air from the pressure vessel 25 flows via the line 18 into the space 16 of the lifting cylinder. This lies on it with its surface on the vehicle wheel and / or on the Castors, whereupon they can be blocked or the vehicle wheel can be lifted.
Zum Einfahren des Hubzylinders 14 wird das Ventil 19 zur Atmosphäre verbunden, worauf die Druckluft aus dem Raum 16 entweichen kann.To retract the lifting cylinder 14, the valve 19 becomes the atmosphere connected, whereupon the compressed air can escape from the space 16.
Anstelle eines Luftpressers 23 kann auch eine Druckmittelquelle treten, die flüssiges Druckmittel fördert, z. B. eine Zahnradpumpe.Instead of an air compressor 23, a pressure medium source can also be used, the liquid pressure medium promotes, z. B. a gear pump.
