Definitions
- the invention relates to a device for disassembling a wheel bearing housing, which is used as a separate component in a receiving bore of an axle body of a motor vehicle axle and fixedly receives a wheel bearing, which serves for rotatable and axially fixed mounting of a provided with a bearing hub and a mounting flange wheel carrier and wherein a traction device is provided, which is directly or indirectly brought into train connection with the wheel bearing housing or the wheel bearing.
- axle constructions which, due to the required lightweight construction, have axle bodies or stub axles which consist of an aluminum alloy. Due to this fact rolling bearings, which serve for the rotatable and axially stationary mounting of a wheel carrier and thus the entire impeller, can not be arranged directly in the axle body, since the aluminum alloy does not allow in particular a pressing of such a wheel bearing.
- now constructions have become known in which a separate wheel bearing housing made of steel is provided, which receives the actual wheel bearing. This wheel bearing housing is now used in a receiving bore of the axle body and fixedly connected by means of several mounting screws with the axle body.
- wheel bearing housings There are basically two types of wheel bearing housings known wherein in a construction, the wheel bearing housing itself forms the outer ring of the actual wheel bearing. In other constructions, the wheel bearing housing is provided with a receiving bore for inserting the complete wheel bearing with inner ring and outer ring.
- a device for disassembling a wheel bearing housing which has a traction device, which is directly or indirectly brought into train connection with the wheel bearing housing or the wheel bearing.
- This device is intended for axle constructions, in which the wheel bearing housing has radially projecting flange sections with through holes, via which the wheel bearing housing is fastened to the axle body.
- the wheel bearing housing receives the wheel bearing, via which in turn the wheel carrier with its bearing hub is mounted rotatably and axially fixed in the wheel bearing housing.
- this wheel carrier serves to receive the brake disk and the running wheel of the motor vehicle.
- the mounting flange of the wheel carrier and attached to the mounting flange brake disc is provided with a plurality of through holes or openings. Through these through holes or openings through the mounting screws of the wheel bearing housing are accessible from the outside. This means that the mounting screws on the one hand project through the flange portions of the wheel bearing housing and into corresponding, behind these flange sections lying threaded holes of the axle body are screwed.
- a plurality of thrust pins are provided in the known device, which axially support a support plate located axially in front of the wheel through the apertures of the brake disc and the through holes of the mounting flange of the wheel carrier and the through holes of said flange portions of Wheel bearing housing can be inserted therethrough.
- These pressure pins can be screwed into the mounting thread of the axle body, so that they are fixedly arranged on the axle body.
- the support plate in turn is provided with a pulling device in the form of a pressing device which is axially supported during the stripping process of the wheel bearing housing via the support plate and the pressure pin on the axle.
- this known device is constructed extremely expensive, this can only be used if the mounting thread for the wheel bearing housing are arranged in the axle body itself. Furthermore, on the one hand the brake disc with openings and on the other hand the mounting flange of the wheel carrier must be provided with through holes through which the thrust pin can be plugged. If the mounting threads are arranged in the axle body, the diameter of the through holes of the flange portions of the wheel bearing housing is greater than that of the mounting threads, so that the pressure pins can be brought into engagement with the mounting threads of the axle body and can support itself axially there.
- axle structures have become known in which the wheel bearing housing is also used on an axle body in a corresponding receiving bore.
- the attachment of the wheel bearing housing on the axle body is carried out here by means of several mounting screws, in this type of axle designs
- the back of the axle body are used. That is, the mounting screws are first inserted from the back of the axle body through corresponding through holes of the axle body and screwed into corresponding mounting thread of the wheel bearing housing.
- the mounting threads which are smaller in diameter than the through holes of the axle body, a pushing through the thrust pin and thus an axial support in the region of the through holes of the axle body does not allow.
- axle constructions are also known in which the wheel carrier with its bearing hub is seated firmly and non-replaceably received in the wheel bearing. If, in such constructions, the mounting flange of the wheel carrier has no apertures or through holes for the accessibility of the mounting thread of the axle, also no axial support of the support plate or the hydraulic cylinder take place on the axle, especially since the mounting thread of the axle are not accessible from the outside.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Demontage eines Radlagergehäuses, welches als separates Bauteil in einer Aufnahmebohrung eines Achskörpers einer Kraftfahrzeugachse eingesetzt ist und ein Radlager feststehend aufnimmt, welches zur drehbaren und axial feststehenden Lagerung eines mit einer Lagernabe und einem Montageflansch versehenen Radträgers dient und wobei eine Zugvorrichtung vorgesehen ist, welche mit dem Radlagergehäuse oder dem Radlager unmittelbar oder mittelbar in Zugverbindung bringbar ist.The invention relates to a device for disassembling a wheel bearing housing, which is used as a separate component in a receiving bore of an axle body of a motor vehicle axle and fixedly receives a wheel bearing, which serves for rotatable and axially fixed mounting of a provided with a bearing hub and a mounting flange wheel carrier and wherein a traction device is provided, which is directly or indirectly brought into train connection with the wheel bearing housing or the wheel bearing.
Kraftfahrzeuge neuerer Art sind mit Achskonstruktionen versehen, welche aufgrund der geforderten Leichtbauweise Achskörper oder Achsschenkel aufweisen, welche aus einer Aluminiumlegierung bestehen. Aufgrund dieser Tatsache sind Wälzlager, welche zur drehbaren und axial feststehenden Lagerung eines Radträgers und damit des gesamten Laufrades dienen, nicht direkt im Achskörper anordenbar, da die Aluminiumlegierung insbesondere ein Einpressen eines solchen Radlagers nicht zulässt. Diesbezüglich sind nun Konstruktionen bekannt geworden, bei welchen ein separates Radlagergehäuse aus Stahl vorgesehen ist, welches das eigentliche Radlager aufnimmt. Dieses Radlagergehäuse ist nunmehr in einer Aufnahmebohrung des Achskörpers eingesetzt und mittels mehrerer Montageschrauben mit dem Achskörper feststehend verbunden. Dabei sind grundsätzlich zwei Arten von Radlagergehäusen bekannt, wobei bei einer Konstruktion das Radlagergehäuse selbst den Außenring des eigentlichen Radlagers bildet. Bei anderen Konstruktionen ist das Radlagergehäuse mit einer Aufnahmebohrung zum Einsetzen des kompletten Radlagers mit Innenring und Außenring ausgestattet.Motor vehicles of a newer type are provided with axle constructions, which, due to the required lightweight construction, have axle bodies or stub axles which consist of an aluminum alloy. Due to this fact rolling bearings, which serve for the rotatable and axially stationary mounting of a wheel carrier and thus the entire impeller, can not be arranged directly in the axle body, since the aluminum alloy does not allow in particular a pressing of such a wheel bearing. In this regard, now constructions have become known in which a separate wheel bearing housing made of steel is provided, which receives the actual wheel bearing. This wheel bearing housing is now used in a receiving bore of the axle body and fixedly connected by means of several mounting screws with the axle body. There are basically two types of wheel bearing housings known wherein in a construction, the wheel bearing housing itself forms the outer ring of the actual wheel bearing. In other constructions, the wheel bearing housing is provided with a receiving bore for inserting the complete wheel bearing with inner ring and outer ring.
Bei solchen Konstruktionen, bei welchen der Achskörper aus einer Aluminiumlegierung besteht und in dessen Aufnahmebohrung ein Radlagergehäuse eingesetzt ist, hat sich nun gezeigt, dass nach längerer Betriebsdauer und der damit einhergehenden Korrosion ein solches Radlagergehäuse nur schwer zum Wechsel des Radlagers aus der Aufnahmebohrung des Achskörpers ausgezogen werden kann.In such constructions, in which the axle body consists of an aluminum alloy and in the receiving bore a wheel bearing housing is used, it has now been shown that after prolonged operation and the associated corrosion such a wheel bearing housing difficult to remove the wheel bearing from the receiving bore of the axle body can be.
Aus der
Um nun ein solches Radlagergehäuse vom Achskörper abziehen zu können, sind bei der bekannten Vorrichtung mehrere Druckzapfen vorgesehen, welche zur axialen Abstützung einer axial vor dem Radträger liegenden Stützplatte durch die Durchbrüche der Bremsscheibe und die Durchgangsbohrungen des Montageflansches des Radträgers sowie die Durchgangsbohrungen der genannten Flanschabschnitte des Radlagergehäuses hindurch steckbar sind. Diese Druckzapfen können in die Montagegewinde des Achskörpers eingeschraubt werden, so dass diese feststehend am Achskörper angeordnet sind. Die Stützplatte ihrerseits wiederum ist mit einer Zugvorrichtung in Form einer Pressvorrichtung versehen, welche sich während des Abziehvorganges des Radlagergehäuses über die Stützplatte und die Druckzapfen am Achskörper axial abstützt.In order to be able to deduct such a wheel bearing housing from the axle, a plurality of thrust pins are provided in the known device, which axially support a support plate located axially in front of the wheel through the apertures of the brake disc and the through holes of the mounting flange of the wheel carrier and the through holes of said flange portions of Wheel bearing housing can be inserted therethrough. These pressure pins can be screwed into the mounting thread of the axle body, so that they are fixedly arranged on the axle body. The support plate in turn is provided with a pulling device in the form of a pressing device which is axially supported during the stripping process of the wheel bearing housing via the support plate and the pressure pin on the axle.
Von dem abgesehen, dass diese bekannte Vorrichtung äußerst aufwändig aufgebaut ist, kann diese auch nur dann eingesetzt werden, wenn die Montagegewinde für das Radlagergehäuse im Achskörper selbst angeordnet sind. Des Weiteren muss einerseits die Bremsscheibe mit Durchbrüchen und andererseits der Montageflansch des Radträgers mit Durchgangsbohrungen versehen sein, durch welche die Druckzapfen hindurch steckbar sind. Sofern die Montagegewinde im Achskörper angeordnet sind, ist der Durchmesser der Durchgangsbohrungen der Flanschabschnitte des Radlagergehäuses größer als die der Montagegewinde, so dass die Druckzapfen mit den Montagegewinden des Achskörpers in Eingriff bringbar sind und sich dort axial abstützen können.Apart from the fact that this known device is constructed extremely expensive, this can only be used if the mounting thread for the wheel bearing housing are arranged in the axle body itself. Furthermore, on the one hand the brake disc with openings and on the other hand the mounting flange of the wheel carrier must be provided with through holes through which the thrust pin can be plugged. If the mounting threads are arranged in the axle body, the diameter of the through holes of the flange portions of the wheel bearing housing is greater than that of the mounting threads, so that the pressure pins can be brought into engagement with the mounting threads of the axle body and can support itself axially there.
Des Weiteren sind jedoch auch Achskonstruktionen bekannt geworden, bei welchen das Radlagergehäuse ebenfalls an einem Achskörper in einer entsprechenden Aufnahmebohrung eingesetzt ist. Die Befestigung des Radlagergehäuses am Achskörper erfolgt hier auch mittels mehrerer Montageschrauben, die bei dieser Art von Achskonstruktionen allerdings rückseitig vom Achskörper her eingesetzt sind. D.h., dass die Montageschrauben zunächst von der Rückseite des Achskörpers durch entsprechende Durchgangsbohrungen des Achskörpers hindurch gesteckt und in entsprechende Montagegewinde des Radlagergehäuses eingeschraubt sind. Dies hat aber zwangsläufig zur Folge, dass die Montagegewinde, welche in ihrem Durchmesser kleiner ausgebildet sind als die Durchgangsbohrungen des Achskörpers, ein Durchstecken der Druckzapfen und damit eine axiale Abstützung im Bereich der Durchgangsbohrungen des Achskörpers nicht erlauben.Furthermore, however, axle structures have become known in which the wheel bearing housing is also used on an axle body in a corresponding receiving bore. The attachment of the wheel bearing housing on the axle body is carried out here by means of several mounting screws, in this type of axle designs However, the back of the axle body are used. That is, the mounting screws are first inserted from the back of the axle body through corresponding through holes of the axle body and screwed into corresponding mounting thread of the wheel bearing housing. But this inevitably has the consequence that the mounting threads, which are smaller in diameter than the through holes of the axle body, a pushing through the thrust pin and thus an axial support in the region of the through holes of the axle body does not allow.
Des Weiteren sind auch Achskonstruktionen bekannt, bei welchen der Radträger mit seiner Lagernabe festsitzend und nicht austauschbar im Radlager aufgenommen ist. Sofern bei solchen Konstruktionen der Montageflansch des Radträgers keine Durchbrüche oder Durchgangsbohrungen für die Zugänglichkeit der Montagegewinde des Achskörpers aufweist, kann ebenfalls keine axiale Abstützung der Stützplatte bzw. des Hydraulikzylinders am Achskörper stattfinden, da insbesondere die Montagegewinde des Achskörpers von außen nicht zugänglich sind.Furthermore, axle constructions are also known in which the wheel carrier with its bearing hub is seated firmly and non-replaceably received in the wheel bearing. If, in such constructions, the mounting flange of the wheel carrier has no apertures or through holes for the accessibility of the mounting thread of the axle, also no axial support of the support plate or the hydraulic cylinder take place on the axle, especially since the mounting thread of the axle are not accessible from the outside.
Um dennoch ein Lagergehäuse bei den vorgenannten Achskonstruktionen abziehen zu können, ist aus der
Insoweit ist diese Konstruktion nach der
Dabei hat sich jedoch gezeigt, dass bei längerer Betriebsdauer eines Kraftfahrzeuges das Radlagergehäuse derart festsitzend in der Aufnahmebohrung des Achskörpers sitzt, dass die Schlagimpulse nicht ausreichend sind, um das Radlagergehäuse aus dem Achskörper ausziehen zu können.However, it has been shown that with longer operating life of a motor vehicle, the wheel bearing housing sits tightly in the receiving bore of the axle body, that the impact pulses are not sufficient to take the wheel bearing housing from the axle body can.
Demgemäß liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit welcher insbesondere äußerst hohe Druckkräfte bzw. Zugkräfte auf ein in einen Achskörper eingesetztes Radlagergehäuse direkt oder indirekt aufbringbar sind.Accordingly, the invention has for its object to provide a device with which in particular extremely high compressive forces or tensile forces can be applied directly or indirectly to an inserted into an axle wheel bearing housing.
Die Aufgabe wird erfindungsgemäß zusammen mit den Merkmalen des Oberbegriffes des Anspruches 1 dadurch gelöst, dass eine Lagerplatte vorgesehen ist, welche im Umgebungsbereich des Radlagergehäuses am Achskörper feststehend aufsetzbar ist und dass die Zugvorrichtung als Hydraulikzylinder ausgebildet ist, welcher zur Kopplung mit dem Radlager oder dem Radlagergehäuse eine Zugstange aufweist und dass der Hydraulikzylinder an der Lagerplatte über ein oder mehrere Stützelemente, insbesondere über eine Stützglocke in axialem Abstand zum Radlagergehäuse am Achskörper festlegbar ist.The object is achieved according to the invention together with the features of the preamble of
Durch die erfindungsgemäße Ausgestaltung findet eine direkte Abstützung der vom Hydraulikzylinder aufgebrachten Auspresskräfte bzw. Zugkräfte am Achskörper selbst statt. Hierzu ist eine Lagerplatte vorgesehen, welche insbesondere im Umgebungsbereich des Radlagergehäuses am Achskörper feststehend aufsetzbar ist. Hierzu sei angemerkt, dass im Umgebungsbereich des Radlagergehäuses, insbesondere auch in einem radialen Abstand zur Lagerachse des darin befindlichen Radlagers, welcher größer ist als der Durchmesse des Radlagergehäuses, diverse Befestigungspunkte stets vorhanden sind, an welchen beispielsweise eine Art Spritzblech oder dgl. zum Schutz beispielsweise der Bremsscheibe angeordnet ist. Diese Befestigungspunkte werden vorliegend eingesetzt, um die Lagerplatte unmittelbar oder mittelbar am Achskörper anzusetzen und zu fixieren. Dabei wird die Lagerplatte rechtwinklig zur Lagerachse des Radlagers bzw. Radlagergehäuses ausgerichtet. Des Weiteren kann aufgrund dieser Konstruktion als Zugvorrichtung ein Hydraulikzylinder vorgesehen werden, welcher zur Kopplung mit dem Radlager oder dem Radlagergehäuse eine Zugstange aufweist. Der Hydraulikzylinder ist dabei an der Lagerplatte Stützelemente, insbesondere über eine Art Stützglocke in axialem Abstand zum Radlagergehäuse am Achskörper festlegbar.The embodiment according to the invention provides direct support for the pressing forces or tensile forces applied by the hydraulic cylinder to the axle body itself. For this purpose, a bearing plate is provided, which is fixed in particular in the surrounding area of the wheel bearing housing on the axle body. It should be noted that in the vicinity of the wheel bearing housing, in particular at a radial distance to the bearing axis of the wheel bearing therein, which is greater than the diameter of the wheel bearing housing, various attachment points are always present, which, for example, a kind of dashboard or the like. For example the brake disc is arranged. These attachment points are used here to attach the bearing plate directly or indirectly on the axle and fix. The bearing plate is aligned at right angles to the bearing axis of the wheel bearing or wheel bearing housing. Furthermore, due to this construction as a pulling device, a hydraulic cylinder can be provided which has a pull rod for coupling to the wheel bearing or the wheel bearing housing. The hydraulic cylinder is fixed to the bearing plate supporting elements, in particular via a kind of support bell at an axial distance to the wheel bearing housing on the axle.
D.h., dass der Hydraulikzylinder in Verbindung mit seiner Zugstange, welche zum Abziehen des Radlagergehäuses die Lagernabe des Radträgers zusammen mit dem Radlagergehäuse, dem Radlager sowie die Aufnahmebohrung für das Radlagergehäuse durchragt, insbesondere am Radlagergehäuse oder dessen Radlager feststehend festlegbar ist. Aufgrund der Verwendung eines Hydraulikzylinders und der Abstützung dieses Hydraulikzylinders über die Stützelemente bzw. insbesondere die Stützglocke sind äußerst hohe Kräfte bis weit über 10 t zum Ausziehen des Radlagergehäuses aus der Aufnahmebohrung des Achskörpers aufbringbar.That is, the hydraulic cylinder in conjunction with its pull rod, which extends through the bearing hub of the wheel carrier together with the wheel bearing housing, the wheel bearing and the receiving bore for the wheel bearing housing, in particular on the wheel bearing housing or its wheel bearing is fixed fixed. Due to the use of a hydraulic cylinder and the support of this hydraulic cylinder on the support elements or in particular the support bell are extremely high forces until well over 10 t for removing the wheel bearing housing from the receiving bore of the axle body applied.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Unteransprüchen entnehmbar.Further advantageous embodiments of the invention can be taken from the further subclaims.
So kann gemäß Anspruch 2 vorgesehen sein, dass die Lagerplatte mehrere Gewindebohrungen aufweist, in welche jeweils eine Abstandshülse einschraubbar ist und dass die Abstandshülsen jeweils eine Durchgangsbohrung aufweisen, durch welche jeweils eine Montageschraube hindurch steckbar ist und, dass die Anordnung der Gewindebohrungen in der Lagerplatte derart gewählt ist, dass die Montageschrauben in eine vorhandenes Gewindebohrung des Achskörpers einschraubbar sind. Durch diese Ausgestaltung ist insbesondere die Lagerplatte in äußerst einfacher Weise feststehend und rechtwinklig zur Drehachse des Radlagers ausgerichtet am Achskörper fixierbar. Zur rechtwinkligen Ausrichtung bezüglich der Lagerachse sind insbesondere die Abstandshülsen vorgesehen, welche die unterschiedliche axiale Anordnung der Befestigungspunkte mit ihrem Gewindebohrungen ausgleichen.Thus it can be provided according to claim 2, that the bearing plate has a plurality of threaded holes, in each of which a spacer sleeve is screwed and that the spacer sleeves each have a through hole through which a mounting screw is plugged through and that the arrangement of the threaded holes in the bearing plate so is chosen that the mounting screws are screwed into an existing threaded hole of the axle body. By this configuration, in particular the bearing plate in a very simple manner fixed and aligned at right angles to the axis of rotation of the wheel bearing on the axle body fixable. For orthogonal alignment with respect to the bearing axis in particular the spacer sleeves are provided, which compensate for the different axial arrangement of the attachment points with their threaded holes.
Des Weiteren kann hierzu gemäß Anspruch 3 vorgesehen sein, dass die Abstandshülsen in der Lagerplatte axial verstellbar aufgenommen sind. Durch diese Ausgestaltung ist insbesondere eine rechtwinklige Ausrichtung der Lagerplatte zur Lagerachse des Radlagers bzw. des Radlagergehäuses einstellbar. Damit sind auch insbesondere Toleranzen der axialen Lage der Befestigungspunkte des Achskörpers ausgleichbar.Furthermore, it can be provided for this purpose according to

Gemäß Anspruch 5 kann weiter vorgesehen sein, dass in der Lagerplatte anstatt der Gewindebohrungen oder zusätzlich zu den Gewindebohrungen Durchgangsbohrungen vorgesehen sind, welche in der Lagerplatte derart positioniert sind, dass die Lagerplatte durch entsprechende Montageschrauben an unterschiedlich gestalteten Achskörpern feststehend montierbar ist. Diese Ausgestaltung erlaubt einen äußerst variablen Einsatz der Lagerplatte an unterschiedlich gestalteten Achskörpern mit unterschiedlich positionierten Aufnahmepunkten.According to
Durch die Ausgestaltung gemäß Anspruch 6 ist die Lagerplatte äußerst geringem Abstand zum Achskörper an diesem anordenbar. Dazu ist vorgesehen, dass die Lagerplatte einen Durchbruch aufweist, welcher im am Achskörper montiertem Zustand das Radlagergehäuse zumindest teilweise umschließt.Due to the configuration according to
Weiter kann gemäß Anspruch 7 vorgesehen sein, dass der Durchbruch ein oder mehrere radiale Aussparungen aufweist. Da die Lagerplatte an unterschiedlich gestalteten Achskörpern und insbesondere zum Ausziehen von unterschiedlich gestalteten Radlagergehäusen mit unterschiedlich radial vorstehenden Montageflanschen vorgesehen sein soll, sind in den Aussparungen entsprechend am Radlagergehäuse angeordnete Montageflansche aufnehmbar.Further, it can be provided according to claim 7 that the breakthrough has one or more radial recesses. Since the bearing plate should be provided on differently shaped axle bodies and in particular for taking off differently shaped wheel bearing housings with differently radially protruding mounting flanges, assembly flanges arranged correspondingly on the wheel bearing housing can be accommodated in the recesses.
Durch die Ausgestaltung gemäß Anspruch 8 wird eine kostengünstige Herstellung der Stützglocke ermöglicht. Hierzu ist vorgesehen, dass die Stützglocke zweiteilig ausgebildet ist und einen Stützzylinder und eine Stützplatte bildet.Due to the configuration according to
Weiter kann gemäß Anspruch 9 vorgesehen sein, dass die Stützglocke bzw. der Stützzylinder der Stützglocke zwei zur Lagerplatte hin ausgerichtete Führungszapfen aufweist, welche in zwei entsprechende Passbohrungen der Stützplatte passend einsteckbar sind. Durch diese Ausgestaltung wird ein selbständiger Halt der Stützglocke an der Lagerplatte erreicht, wodurch die Handhabung der erfindungsgemäßen Vorrichtung erleichtert wird.It can further be provided according to
Gemäß Anspruch 10 kann weiter vorgesehen sein, dass die Lagerplatte zur Stützglocke hin im Umgebungsbereich des Durchbruches eine Einsenkung aufweist, in welche die Stützglocke bzw. deren Stützzylinder mit geringem Spiel einsetzbar ist. Durch diese Ausgestaltung wird das Ansetzen der Stützglocke an der Lagerplatte ebenfalls erleichtert. Dabei kann die Ausgestaltung gemäß anspruch 10 auch in Kombination mit der Ausgestaltung gemäß Anspruch 9 vorgesehen werden.According to claim 10 can be further provided that the bearing plate to the support bell out in the vicinity of the opening has a depression, in which the support bell or its support cylinder can be used with little play. By this configuration, the attachment of the support bell on the bearing plate is also facilitated. The embodiment according to claim 10 can also be provided in combination with the embodiment according to
Durch die gemäß Anspruch 11 gewählten Abmessungen der Stützglocke bzw. des Stützzylinders der Stützglocke wird eine zusätzliche Führung der Stützglocke am Radträger erreicht, wodurch ein verbesserter Halt der am Achskörper bzw. an der Lagerplatte angesetzten Stützglocke erreicht wird.Due to the selected according to claim 11 dimensions of the support bell or the support cylinder of the support bell additional guidance of the support bell is achieved on the wheel, whereby an improved grip of the attached to the axle or on the bearing plate support bell is achieved.
Hierzu sein angemerkt, dass der Hydraulikzylinder auch über anders gestaltete Stützelement an der Lagerplatte festgelegt sein kann. Insbesondere sind hier auch Stützstangen oder dgl. denkbar, welche eine Verbindung zwischen der Lagerplatte und einer Stützplatte herstellen. Die Stützplatte dient dabei ebenfalls zur feststehenden Aufnahme des Hydraulikzylinders. Die lagerplatte jedenfalls ermöglicht ein unmittelbare oder über die Abstandhülse ein mittelbares Einleiten der Presskräfte in den Achskörper, ohne dass am Achskörper eine Beschädigung insbesondere bei äußerst großen Presskräften auftreten kann.For this purpose, it should be noted that the hydraulic cylinder can also be fixed to the bearing plate via a differently configured support element. In particular, support rods or the like are also conceivable here, which produce a connection between the bearing plate and a support plate. The support plate also serves for fixed receiving the hydraulic cylinder. In any case, the bearing plate allows an indirect or via the spacer sleeve an indirect introduction of the pressing forces in the axle body, without damage to the axle body can occur especially at extremely large pressing forces.

Dieser Lagersitz 83 wird radial nach außen durch einen axial vorstehenden Aufnahmesteg 84 begrenzt. Im Bereich dieses Aufnahmestegs 84 sind radial außerhalb der Aufnahmebohrung 82 beim vorliegenden Ausführungsbeispiel insgesamt vier Durchgangsbohrungen 85 vorgesehen, über welche ein Radlagergehäuse feststehend am Achskörper 80 montierbar ist. Des Weiteren ist aus
Oberhalb sowie seitlich neben und unterhalb der Aufnahmebohrung weist der Achskörper 80 mehrere etwa ringförmig ausgebildete Stützelemente 87, 88, 89 und 90 auf, welche im Betrieb beispielsweise zur feststehenden Montage eines Schutzbleches zur Abdeckung beispielsweise einer Bremsscheibe dienen. Dementsprechend weisen diese Stützelemente 87, 88, 89 und 90 jeweils eine entsprechende Gewindebohrung 91, 92, 93 bzw. 94 auf. Auf die Gewindedarstellung dieser Gewindebohrungen 91 bis 94 wurde in
Entsprechend der Anordnung dieser Stützelemente 87 bis 90 sowohl bezüglich deren axialer Positionierung als auch bezüglich deren Winkellage und deren Abstand zur Aufnahmebohrung 82 ist die Ausgestaltung der Lagerplatten 1 und 1/1 mit ihren Abstandshülsen 5 und 6 gewählt. Da die drei Stützelemente 88, 89 und 90 in axialer Richtung des Pfeiles 96 weiter zurückversetzt angeordnet sind, als das obere Stützelement 87, ist entsprechend, wie bereits zu den

Das Radlager 102 dient in der Regel zur drehbaren und axial festsitzenden Lagerung eines Radträgers 107, welcher in
Dabei sind Fahrzeugkonstruktionen bekannt, bei welchen der Radträger 107 axial feststehend und drehbar im Radlager 102 und somit im Radlagergehäuse 100 aufgenommen ist. Bei manchen Konstruktionen lässt sich dieser Radträger 107 nicht aus dem Radlager 102 entfernen, so dass bei einer Beschädigung dieses Radlagers 102 nur die komplette Einheit bestehend aus dem Radträger 107, dem Radlagergehäuse 100 sowie dem Radlager 102 vom Achskörper 80 abgenommen werden muss. Bei anderen Konstruktionen kann der Radträger 107 vor dem Entfernen des Radlagergehäuses 100 aus dem Radlager 102 herausgenommen werden.In this case, vehicle constructions are known in which the
Insoweit sind die beiden Lagerplatten 1 und 1/1 mit ihrem jeweiligen Durchbruch 21 sowie dessen Aussparungen 22 und 23 einerseits an die radiale Ausdehnung des Radlagergehäuses 100 sowie des Montageflansches 108 des Radträgers 107 angepasst. Damit ist sichergestellt, dass insbesondere auch bei nicht demontierbarem Radträger 107 die Lagerplatte 1 bzw. 1/1 über den Montageflansch 108 geschoben und am Achskörper 80 feststehend montiert werden kann. Die Aussparungen 22 und 23 des Durchbruches 21 sind für die Demontage des beispielhaft in

Vor der Aktivierung des Hydraulikzylinders 50 wird zunächst die Zugmutter 60 soweit zugestellt, dass der Stützring 71 mit seinem Stützsteg 75 beispielsweise rückseitig am Radlagergehäuse 100 unter leichter Vorspannung anliegt. Bei Aktivierung des Hydraulikzylinders 50 bewegt sich dessen Hubkolben 53 in Richtung des Pfeiles 54, so dass zwangsläufig das Radlagergehäuse 100 aus dem Achskörper 80 bzw. dessen Aufnahmebohrung 82 ausgezogen wird.Before the activation of the
Es ist erkennbar, dass mittels der erfindungsgemäßen Vorrichtung 115 äußerst hohe Zugkräfte zum Demontieren des Radlagergehäuses 100 aufbringbar sind. So sind hier beispielsweise Hydraulikzylinder 50 einsetzbar, welche eine Axialkraft bis zu 10 t und mehr aufbringen können. Durch die vorgesehene Lagerplatte 1 sind diese hohen Axialkräfte beispielsweise über die Stützelemente 87, 88, 89 und 90 in den Achskörper 80 einleitbar, ohne dass hier irgendwelche Beschädigungen auftreten können. Des Weiteren ergibt sich durch die Ausrichtung der Lagerplatte 1 quer zur Lagerachse 86 eine absolut konzentrische Einleitung der Zugkräfte in das Radlagergehäuse 100, so dass ein Verkanten beim Ausziehvorgang des Radlagergehäuses 100 sicher ausgeschlossen ist.It can be seen that 115 extremely high tensile forces for disassembling the
Es ist beispielsweise auch vorstellbar, je nach Ausgestaltung und Anordnung der Stützelemente 87 bis 90, wenn diese in derselben Ebene wie die Frontfläche 95 des Achskörpers 80 liegen, dass sich die Lagerplatte 1 flächig am Achskörper 80 bzw. der gesamten Frontfläche 95 abstützt. In einem solchen Fall sind die Abstandshülsen 5 und/oder 6 nicht zwingend notwendig.It is also conceivable, for example, depending on the configuration and arrangement of the

Die weiteren in den Lagerplatten 1 und 1/1 vorgesehenen Durchgangsbohrungen 11 bis 15, von welchen auch eine größere Anzahl in weiteren unterschiedlichen Anordnungen vorgesehen sein können, dienen zum Ansetzen der Lagerplatte 1 bzw. 1/1 an Achskörpern, bei welchen die Stützelemente in anderer Weise positioniert sind. Hierzu werden, wie bereits oben erwähnt, zur feststehenden Montage der Lagerplatte 1 bzw. 1/1 über die weiteren Durchgangsbohrungen 11 bis 15 die zu
