Abstract
Description
Die Erfindung betrifft eine Reifenprüfmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a tire testing machine according to the preamble of claim 1.
Eine derartige, beispielsweise aus
der
In der Reifenprüfmaschine erfolgt die Messung der Gleichförmigkeit des Luftreifens. Hierzu ist es erforderlich, dass der Reifen zwischen den beiden Messfelgen eine stabile Lage einnimmt. Insbesondere ist es erforderlich, dass die radiale Steifigkeit zwischen Reifen und Felge während des Prüfvorganges unverändert bleibt, um unverfälschte Messergebnisse zu erhalten. Hierzu ist es erforderlich, dass der Reifen beim Einlagern in diese stabile Position an den Reifensitzflächen der Messfelgenhälften gleiten bzw. rutschen kann.The measurement is carried out in the tire testing machine of uniformity of the pneumatic tire. This requires that the tire be between the two measuring rims occupies a stable position. In particular is it requires that the radial rigidity between tires and Rim during the test procedure remains unchanged, for genuine Get measurement results. This requires that the tire when stored in this stable position on the tire seats Measuring rim halves can slide or slide.
Bei herkömmlichen Reifenprüfmaschinen wird der Messstation eine Reifenseifstation vorgeschaltet, in welcher der Reifen mit einem Schmiermittel, insbesondere Seifenmittel, an der Reifensitzfläche geseift wird, um ein unbehindertes Rutschen bzw. Gleiten der Reifensitzfläche, z.B. Reifenwülste an den Reifenaufnahmeflächen der Messfelgenhälften zu gewährleisten. Derartige Reifenseifstationen sind äußerst aufwendig und verursachen hohe Instandhaltungskosten und erfordern ein ständiges Nachfüllen des Seifenmittels. Außerdem lässt sich eine Verunreinigung der Umgebung mit dem Seifenmittel nur mit hohem Aufwand vermeiden.In conventional tire testing machines a tire soap station upstream of the measuring station, in which the tire with a lubricant, especially soap the tire seat is soaped to prevent the tire seat surface from sliding or sliding freely, e.g. Tire beads on the tire receiving surfaces the measuring rim halves to ensure. Tire soap stations of this type are extremely complex and cause high maintenance costs and require constant refilling of the Soap agent. Moreover can be one Pollution of the environment with the soap is very difficult avoid.

Bei Messfelgen mit gestuften Reifenaufnahmeflächen, wie sie bei einer Reifenprüfmaschine aus der 91/14165 A1 bekannt sind, werden zum erleichterten Rutschen der Reifensitzfläche in die entsprechende Felgenkontur Füllringe an den jeweiligen Konturstufen vorgesehen. Auch hierbei handelt es sich um eine relativ aufwendige Maßnahme, um den zu prüfenden Reifen in eine stabile Position zu bringen.For measuring rims with stepped tire mounting surfaces, such as at a tire testing machine from 91/14165 A1 are known to facilitate sliding the tire seat in the corresponding rim contour filler rings at the respective contour levels intended. This is also a relatively complex process Measure, to the one to be checked Bring tires into a stable position.
Aufgabe der Erfindung ist es, eine Reifenprüfmaschine der eingangs genannten Art zu schaffen, bei welcher mit einfachen Mitteln, insbesondere zur Vermeidung einer zusätzlichen Reifenseifstation eine stabile Position des zu prüfenden Reifens zwischen den beiden Messfelgen erreicht wird.The object of the invention is a tire testing to create the type mentioned, in which with simple Means, especially to avoid an additional tire soap station stable position of the test item Tire between the two measuring rims is reached.
Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Patentanspruches 1 gelöst.This object is achieved by the Characteristic of claim 1 solved.
Bei der Erfindung sind zumindest die Reifenaufnahmeflächen der Messfelgenhälften, auf denen die Reifensitzflächen, insbesondere Reifenwülste in eine stabile Lage gebracht werden, mit einem fest anhaftenden Trockenschmierfilm beschichtet.In the invention are at least the tire receiving surfaces the measuring rim halves, on which the tire seats, especially tire beads be placed in a stable position with a firmly adhering Dry lubrication film coated.
Der Trockenschmierfilm ist im wesentlichen aus Wolframdisulfid gebildet. Vorzugsweise ist der Trockenschmierfilm auf den Reifenaufnahmeflächen der Messfelgen in einer Schichtdicke im μm-Bereich, insbesondere von 0,5 μm und geringer, aufgetragen.The dry lubrication film is essentially out Tungsten disulfide formed. Preferably the dry lubrication film is on the tire receiving surfaces of the Measuring rims in a layer thickness in the μm range, in particular from 0.5 μm and less, plotted.
