Description

Vorrichtung zur Befestigung einer Achsmeß- einrichtung an einer Felge eines Rades an einem Kraftfahrzeug Device for attaching an axle measuring device to a rim of a wheel on a motor vehicle
Die Erfindung betrifft eine Vorrichtung der im Oberbegriff des Anspruchs 1 genannten Art zur Befestigung einer Achsmeßeinrichtung an einer Felge eines Ra- des an einem Kraftfahrzeug.The invention relates to a device of the type mentioned in the preamble of claim 1 for fastening an axle measuring device to a rim of a wheel on a motor vehicle.
Vorrichtungen zur Befestigung einer Achsmeßeinrichtung an einer Felge eines Rades an einem Kraftfahrzeug sind allgemein bekannt. Sie weisen einen Grundkörper auf, an dem die Achsmeßeinrichtung in einer vor- bestimmten Bezugsrichtung in bezug zu dem Grundkörper befestigbar ist. An dem Grundkörper sind drei sich in einer Ebene senkrecht zu der Bezugsrichtung im wesentlichen radial erstreckende Stützarme angeordnet, an denen jeweils längsverstellbar Abstandshalter befestigt sind, deren zur Dreipunktauflage an einer Felge dienenden Enden in einer Ebene senkrecht zu der Bezugsrichtung liegen. Außerdem sind Mittel zur Halterung der Vorrichtung an der Felge vorgesehen.Devices for fastening an axle measuring device to a rim of a wheel on a motor vehicle are generally known. They have a base body to which the wheel alignment device can be fastened in a predetermined reference direction with respect to the base body. Arranged on the base body are three support arms which extend substantially radially in a plane perpendicular to the reference direction and to which spacers are attached in each case in a longitudinally adjustable manner, the ends of which serve for three-point support on a rim lie in a plane perpendicular to the reference direction. Means for holding the device on the rim are also provided.
Durch die Firmendruckschrift "Achsmeßanlage Laser- System HD-20-zur Messung aller Fahrzeugtypen", 9/98, der Firma HAWEKA Auswuchttechnik Horst Warkotsch GmbH in D-30928 Burgwedel sowie durch DE 298 20 769 Ul ist eine Vorrichtung der im Oberbegriff des Anspruchs 1 genannten Art bekannt. Zur verstellbaren Anordnung der Anlagezapfen an der Anlagefläche des Grundkörpers dienen Schrauben, die durch Schlitze in Armen des Grundkörpers ragen und in Gewindebohrungen der Anlagezapfen eingeschraubt sind. Zum einfachen Festziehen und Lösen der Schrauben weisen deren Köpfe RändelScheiben auf. Die Gewindebohrungen sind exzentrisch zu den Anlagezapfen angeordnet, so daß diese jeweils um ihre Gewinde- bohrung schwenkbar und somit auch in Umfangsrichtung verstellbar sind. Durch Lösen einer Rändelschraube eines Zapfens ist dessen Lage somit sowohl in Radialrichtung als auch in beschränktem Maße in Umfangsrichtung veränderbar und so an die Felge eines Rades an einer zu vermessenden Achse eines Kraftfahrzeuges anpaßbar. Die- ses Erfordernis besteht deshalb, weil die Befestigungslöcher bzw. Befestigungsmuttern von Felgen unterschiedlicher Typen unterschiedliche Umfangsabstände und Radialabstände haben.The device "Axle measuring system laser system HD-20-for measuring all types of vehicles", 9/98, the company HAWEKA Auswuchttechnik Horst Warkotsch GmbH in D-30928 Burgwedel and DE 298 20 769 Ul is a device in the preamble of claim 1 known type known. Screws which protrude through slots in the arms of the base body and are screwed into tapped holes in the base pin serve for the adjustable arrangement of the contact pins on the contact surface of the base member. For easy tightening and loosening the heads of the screws have knurled washers. The threaded bores are arranged eccentrically to the contact pins, so that they can each be pivoted about their threaded bores and thus can also be adjusted in the circumferential direction. By loosening a knurled screw of a pin, its position can thus be changed both in the radial direction and to a limited extent in the circumferential direction and can thus be adapted to the rim of a wheel on an axle of a motor vehicle to be measured. This requirement exists because the fastening holes or fastening nuts of rims of different types have different circumferential distances and radial distances.
Zwar ist eine solche Anpassung bei dieser bekann- ten Vorrichtung durchführbar, sie ist jedoch umständlich, weil sie vorgenommen werden muß, bevor sich die Vorrichtung in Anlage an einer Felge befindet. Die richtige Lage der Anlagezapfen muß daher vorher abgeschätzt und durch mehrmaliges versuchsweises Anlegen an die Felge endgültig eingestellt werden.Although such an adaptation can be carried out with this known device, it is cumbersome because it has to be carried out before the device is in contact with a rim. The correct position of the contact pin must therefore be estimated beforehand and finally set by repeated application to the rim.

Auch bei dieser bekannten Vorrichtung ist zwar eine Anpassung an unterschiedliche Felgenausführungen und Radmutternanordnungen grundsätzlich möglich, jedoch in gleicher Weise wie bei der zuvor genannten Vorrichtung umständlich.Even with this known device, adaptation to different rim designs and wheel nut arrangements is fundamentally possible, but cumbersome in the same way as with the aforementioned device.
Durch DE 197 04 163 AI ist eine Vorrichtung zur Befestigung einer Achsmeßeinrichtung an einer Felge eines Rades an einem Kraftfahrzeug bekannt, die auf- weist einen Grundkδrper, Mittel an dem Grundkörper zur Befestigung der Achsmeßeinrichtung in einer vorbestimmten Bezugsrichtung in Bezug zu dem Grundkörper, drei Anlagezapfen, die an einer den Mitteln zur Befestigung der Achsmeßeinrichtung abgewandten Anlagefläche des Grundkörpers angeordnet sind und deren zur Dreipunkt - läge an einer Felge dienenden Enden in einer Ebene senkrecht zur Bezugsrichtung liegen. Außerdem sind Haltemittel zur Halterung des Grundkörpers an der Felge vorgesehen, wobei sich die Anlagezapfen an der Anlage- fläche des Grundkörpers befinden. Die Anlagezapfen sind nicht an unterschiedliche Felgenarten und Radmutternanordnungen anpaßbar. Außerdem sind gesonderte Mittel zum Andrücken der Vorrichtung vorgesehen, die umständlich in der Handhabung sind. Der Erfindung liegt die Aufgabe zugrunde, eineDE 197 04 163 AI discloses a device for attaching an axle measuring device to a rim of a wheel on a motor vehicle, which has a base body, means on the base body for attaching the axle measuring device in a predetermined reference direction in relation to the base body, three bearing pins , which are arranged on a contact surface of the base body facing away from the means for fastening the wheel alignment device and whose ends for the three-point position on a rim lie in a plane perpendicular to the reference direction. In addition, holding means are provided for holding the base body on the rim, the contact pins being located on the contact surface of the base body. The system pins cannot be adapted to different types of rims and wheel nut arrangements. In addition, separate means for pressing the device are provided, which are cumbersome to use. The invention has for its object a
Vorrichtung der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, bei der die Anpassung der Lage der drei Anlagezapfen an unterschiedliche Felgentypen mit unterschiedlichen Zahlen und Radialabständen von Be- festigungsmuttern vereinfacht ist.To create device of the type mentioned in the preamble of claim 1, in which the adaptation of the position of the three bearing pins to different types of rims with different numbers and radial distances of fastening nuts is simplified.
Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebene Lehre gelöst .The object on which the invention is based is achieved by the teaching specified in the characterizing part of claim 1.
Der Grundgedanke dieser Lehre besteht darin, die Anlagezapfen durch Haltemagnete mit einer Anlagefläche an dem Grundkörper zu verbinden, die zu diesem Zweck aus magnetisch leitfähigem Material besteht. Auf diese Weise ist es zunächst grundsätzlich möglich, die Halte- zapfen vor dem Ansetzen der Vorrichtung an eine Felge an beliebigen Stellen der Anlagefläche an dem Grundkörper durch die magnetische Anziehung anzubringen und so der jeweiligen Umfangs- und Radialanordnung von Befestigungsmuttern anzupassen und so sicherzustellen, daß keiner der Anlagezapfen auf einer Befestigungsmutter zu liegen kommt.The basic idea of this teaching is that To connect the contact pin by holding magnets with a contact surface on the base body, which for this purpose consists of magnetically conductive material. In this way, it is possible in principle to attach the holding pins to the rim at any point on the contact surface on the base body before attaching the device to the base body and thus to adapt it to the respective circumferential and radial arrangement of fastening nuts and thus to ensure that none of the contact pins come to rest on a fastening nut.
Ein besonderer Vorteil der Erfindung besteht darin, daß es nicht erforderlich ist, die Anlagezapfen zunächst an der Anlagefläche an dem Grundkörper anzu- ordnen, vielmehr ist es möglich, sie zunächst einzeln an den gewünschten Stellen zwischen Radbefestigungsmuttern an einer Felge anzusetzen, wonach es dann nur eines einfachen Ansetzens des Grundkörpers mit seiner Anlagefläche an die drei Anlagezapfen bedarf, wobei die Halterung durch die Haltemagnete an den Anlagezapfen erfolgt. Einer besonderen Aufmerksamkeit beim Ansetzen der erfindungsgemäßen Vorrichtung bedarf es somit überhaupt nicht mehr.A particular advantage of the invention is that it is not necessary to first arrange the contact pins on the contact surface on the base body, rather it is possible first to position them individually at the desired locations between wheel fastening nuts on a rim, after which it is then only a simple attachment of the base body with its contact surface to the three contact pins is required, the mounting being carried out by the holding magnets on the contact pins. Special attention when attaching the device according to the invention is therefore no longer required at all.
Gemäß einer Ausführungsform der Erfindung weist die Anlagefläche an dem Grundkörper Anordnungen vonAccording to one embodiment of the invention, the contact surface on the base body has arrangements of
Befestigungsmuttern verschiedener Typen von Felgen entsprechende Markierungen zum Ansetzen der Anlagezapfen auf. Somit kann vor dem Ansetzen der erfindungsgemäßen Vorrichtung die Anordnung von Markierungen aufgesucht werden, die der Anordnung der Befestigungsmuttern des zu vermessenden Rades entspricht, und an diesen Stellen können dann die drei Anlagezapfen angesetzt werden, so daß völlige Sicherheit besteht, daß beim Ansetzen der Vorrichtung an die Felge die drei Anlagezapfen zwischen Befestigungsmuttern des Rades an der Felge zur Anlage kommen können .Fastening nuts of different types of rims have corresponding markings for attaching the contact pins. Thus, before placing the device according to the invention, the arrangement of markings can be sought, which corresponds to the arrangement of the fastening nuts of the wheel to be measured, and at these points the three bearing pins can then be attached, so that there is complete certainty that when the device is attached the rim the three contact pins between Fastening nuts of the wheel on the rim can come into contact.
Das magnetisch leitfähige Material ist zweckmäßigerweise ganz einfach Stahl. Auch ist es zweckmäßig, daß der gesamte Grundkörper scheibenförmig und somit an seine Scheiben- oder ringförmige Anlagefläche angepaßt ist .The magnetically conductive material is conveniently quite simply steel. It is also expedient that the entire base body is disc-shaped and thus adapted to its disc or ring-shaped contact surface.
Die Größe der Anlagefläche an dem Grundkörper muß natürlich den möglichen Anordnungen von Befestigungs- muttern zu vermessender Ränder entsprechen. Handelt es sich um eine ringförmige Anlagefläche, so sollte diese eine radiale Ausdehnung haben, die den kleinsten und größten Radialabständen von Befestigungsmuttern von Rädern unterschiedlicher Arten entspricht, die an zu messenden Achsen befestigt sind. In einfachen Fällen kann es genügen, wenn nur zwei der Anlagezapfen verstellbar sind und einer fest ist.The size of the contact surface on the base body must of course correspond to the possible arrangements of fastening nuts for edges to be measured. If it is a ring-shaped contact surface, it should have a radial extent which corresponds to the smallest and largest radial distances between fastening nuts of wheels of different types which are fastened to axles to be measured. In simple cases, it may be sufficient if only two of the contact pins are adjustable and one is fixed.
Anhand der Zeichnung soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden. Fig. 1 zeigt ein Ausführungsbeispiel der Erfindung in Verbindung mit einer Felge und Fig. 2 ist ein vergrößerter Teilschnitt durch Fig. 1 im Bereich eines Anlagezapfens. Fig. 1 zeigt einen scheibenförmigen Grundkörper 2, an dem sich koaxial ein Befestigungszapfen 4 zur Anbringung einer nicht dargestellten Achsmeßeinrichtung zur Vermessung der Achse eines Rades befindet, von dem nur eine Felge 6 dargestellt ist.The invention will be explained in more detail using an exemplary embodiment with reference to the drawing. Fig. 1 shows an embodiment of the invention in connection with a rim and Fig. 2 is an enlarged partial section through Fig. 1 in the region of a contact pin. Fig. 1 shows a disc-shaped base body 2, on which there is coaxially a mounting pin 4 for attaching an axle measuring device, not shown, for measuring the axis of a wheel, of which only one rim 6 is shown.
Der Grundkörper 2 weist auf seiner dem Befesti- gungszapfen 4 abgewandten Seite eine Anlagefläche 8 auf, von der lediglich die äußere Kante sichtbar ist.The base body 2 has a contact surface 8 on its side facing away from the fastening pin 4, of which only the outer edge is visible.
In Fig. 1 ist ein Teil des scheibenförmigen Grundkörpers 2 weggeschnitten, so daß zwei Anlagezapfen 10 und 12 von insgesamt drei Anlagezapfen sichtbar sind, die mit ihren Enden 14 und 16 eine Dreipunktanlage an einer Ringfläche 18 zwischen Radbefestigungsmuttern 20 anliegen. Die anderen Enden 22 und 24 der Anlagezapfen 10 und 12 liegen der Anlagefläche 8 gegenüber, wobei sie aus Gründen der besseren Darstellung in Fig. 1 mit Abstand zu der Anlagefläche 8 dargestellt sind.In Fig. 1 part of the disc-shaped base body 2 is cut away, so that two contact pins 10 and 12 of a total of three contact pins are visible, which rest with their ends 14 and 16 a three-point system on an annular surface 18 between wheel fastening nuts 20. The other ends 22 and 24 of the contact pins 10 and 12 lie opposite the contact surface 8, they being shown at a distance from the contact surface 8 in FIG. 1 for reasons of better illustration.
Fig. 2 zeigt vergrößert einen Schnitt durch den Anlagezapfen 12 und benachbarte Teile des Grundkörpers 2 und der Felge 6. Die übrigen zwei Anlagezapfen sind in gleicher Weise ausgebildet. In Fig. 2 ist der Anlagezapfen 12 mit seinem Ende 16 in Anlage an der Ringfläche 18 der Felge 6 gezeigt, während das andere Ende 24 in Anlage an der Anlagefläche 8 des Grundkörpers 2 gezeigt ist, so daß sich insgesamt eine Lage ergibt, in der der Grundkörper 2 mit seinem Befestigungszapfen 4 fest an der Felge 6 angeordnet ist .2 shows an enlarged section through the contact pin 12 and adjacent parts of the base body 2 and the rim 6. The remaining two contact pins are designed in the same way. In Fig. 2, the contact pin 12 is shown with its end 16 in contact with the annular surface 18 of the rim 6, while the other end 24 is shown in contact with the contact surface 8 of the base body 2, so that there is an overall position in which the base body 2 with its fastening pin 4 is fixedly arranged on the rim 6.
Wie aus Fig. 2 ersichtlich, dient der Halterung des Anlagezapfens 12 an der Felge 6 ein Haltemagnet 26, dessen Nord-Süd-Achse senkrecht auf einer Anlagefläche 28 des Anlagezapfens 12 steht, mit der der AnlagezapfenAs can be seen from FIG. 2, the holding pin 12 is held on the rim 6 by a holding magnet 26, the north-south axis of which is perpendicular to a contact surface 28 of the contact pin 12 with which the contact pin
12 an der Ringfläche 18 anliegt. Zum Schließen des magnetischen Kreises dient ein Schuh 30, der mittels einer Schraube 32 an dem Anlagezapfen 12 befestigt ist, so daß sich insgesamt ein magnetischer Kreis ergibt, der durch magnetische Feldlinien 34 symbolisiert ist. Das Ende 24 ist genauso ausgebildet wie das Ende 16. Sich entsprechende Teile sind mit gleichen Bezugsziffern versehen, jedoch zusätzlich mit einem Strich gekennzeichnet. Durch den weiteren Haltemagneten 26' ist somit das Ende 24 fest an der Anlagefläche 8 des12 abuts the annular surface 18. To close the magnetic circuit, a shoe 30 is used, which is fastened to the contact pin 12 by means of a screw 32, so that overall there is a magnetic circuit which is symbolized by magnetic field lines 34. The end 24 is designed in exactly the same way as the end 16. Corresponding parts are provided with the same reference numerals, but additionally marked with a line. Through the further holding magnet 26 ', the end 24 is thus fixed to the contact surface 8 of the
Grundkörpers 2 gehalten.Main body 2 held.
Bei Benutzung der in den Fig. 1 und 2 dargestellten Vorrichtung gemäß der Erfindung werden zunächst die Anlagezapfen 10 und 12 zwischen den Radbefestigungs- muttern 20 an der Ringfläche 18 der Felge 6 angesetzt, der dritte, in Fig. 1 nicht sichtbare Anlagezapfen natürlich in gleicher Weise. Die Anlagezapfen 10, 12 sind danach durch ihre Magnete 26 fest an der Ringfläche 18 der Felge 6 gehalten. Danach wird der scheibenförmigeWhen using the device according to the invention shown in FIGS. 1 and 2, the contact pins 10 and 12 are first between the wheel fastening nuts 20 are attached to the annular surface 18 of the rim 6, the third bearing pin, not visible in FIG. 1, of course in the same way. The contact pins 10, 12 are then held firmly by their magnets 26 on the annular surface 18 of the rim 6. Then the disc-shaped
Grundkörper 2 mit seiner Anlagefläche 8 an die Enden 24 der Anlagezapfen 10, 12 angesetzt, so daß der Grundkörper 2 durch die weiteren Haltemagnete 26' fest mit den Anlagezapfen 10, 12 verbunden ist und dabei gleichzei- tig mit der Felge 8, mit der die Anlagezapfen 10, 12 durch die Haltemagnete 26 verbunden sind.Base body 2 with its contact surface 8 is attached to the ends 24 of the contact pins 10, 12, so that the base body 2 is firmly connected to the contact pins 10, 12 by the further holding magnets 26 'and at the same time to the rim 8 with which the Contact pins 10, 12 are connected by the holding magnets 26.
Bei den beschriebenen Vorgängen kommt es weder auf den genauen Ansetzort der Enden 14, 16 der Anlagezapfen 10, 12 an der Ringfläche 18 der Felge 6 an noch auf den genauen Ansetzort des scheibenförmigen Grundkörpers 2 an den Enden 22, 24 der Anlagezapfen 10, 12. Immer ist gewährleistet, daß der Befestigungszapfen 4 für eine Achsmeßvorrichtung senkrecht auf der durch die Ringfläche 18 bestimmten Fläche steht und damit parallel zu der Achse des Rades, an dem die Felge 6 befestigt ist. Das Lösen des scheibenförmigen Grundkörpers 2 nach dem Meßvorgang kann in sehr einfacher Weise durch eine Drehbewegung oder eine seitliche Bewegung des Grundkörpers 2 im Verhältnis zu der Ringfläche 18 erfolgen, so daß die Anlagezapfen 10, 12 ganz einfach seitlich über die Kanten ihrer Anlageflächen 28, 28' kippen, wobei eine Hebelwirkung auftritt, die das Lösen erleichtert. In the processes described, the exact location of the ends 14, 16 of the contact pins 10, 12 on the annular surface 18 of the rim 6 is not important, nor is the precise location of the disk-shaped base body 2 on the ends 22, 24 of the contact pins 10, 12. It is always ensured that the mounting pin 4 for an axle measuring device is perpendicular to the surface defined by the annular surface 18 and thus parallel to the axis of the wheel to which the rim 6 is attached. The disk-shaped base body 2 can be released in a very simple manner by a rotary movement or a lateral movement of the base body 2 in relation to the annular surface 18, so that the contact pins 10, 12 can easily be moved laterally over the edges of their contact surfaces 28, 28 'tilt, with a leverage effect that facilitates loosening.
