    The invention relates to a wheel bearing tool for 'press-fitting a wheel bearing accommodated in a bearing bore of a bearing housing of an axle body, via which a wheel hub having a wheel hub is mounted rotatably and axially fixedly in the bearing housing, consisting of a pressing device fixable on the axle body and a pressure plate having a recess, whose recess has a support flange with which the pressure plate can be inserted into a space between the hub flange and the wheel hub seated on the wheel bearing and through which during the pressing process caused by the pressing device press-fit forces are transferable to the wheel bearing.
    Wheel bearing tools, in particular for pressing a wheel bearing into the bearing bore of a bearing housing of an axle body, have long been known. In general, such wheel bearing tools on a pressing device, which are fixed in any way on the axle or on the bearing housing. By means of a further tool part, which can be brought into pressure connection with the actual wheel bearing, in particular with its outer ring, such a wheel bearing can be pressed into the corresponding associated bearing bore.
    Reference may be made, for example, to DE 37 30 017 CI. In this article, a " pulling spindle " provided, which on the one hand, the support device, which is attachable to the wheel bearing housing, and on the other hand, a kind of press plate, which is attachable to the wheel bearing, completely penetrates. By a corresponding clamping nut and tightening this tension spindle thus the distance between the attachable to the axle component and the attachable to the wheel bearing component can be shortened, so that a wheel bearing is forcibly pressed into the bearing bore of the bearing housing upon actuation of the tension spindle. A similar construction is also shown in DE 35 30 983 CI, in which also a kind of pulling spindle is provided, which in interaction with an axial support bearing and a Axialdruckstück is able to press a wheel bearing in a corresponding bearing bore of an axle body.
    From DE 202 06 000 Ul, in turn, a tool has become known, by means of which both the Radflanschnabe and the wheel bearing of an axle should be interchangeable. In this construction, a kind of support plate is set on one side of the axle body at a predetermined distance therefrom. To do this, «· * I * · * ·» • · · · * * ··· «« • * ♦ · »· ·» * * * .2 * · .. * * .. * * .. * *. * used various mounting holes of the axle body, which are normally used to hold, for example, the tie rod or a caliper. This support plate has a central through bore through which, for example, the piston rod of a hydraulic cylinder can be inserted therethrough. By Verkontern with a corresponding pull nut axial pressing forces can thus be applied via this hydraulic cylinder. In this case, the displaceable in the hydraulic cylinder piston rod extends through the wheel bearing and the bearing housing of the axle body and the support plate, wherein the back of the support plate, the above-mentioned pull nut is screwed. Between the tension nut and the support plate can still be provided various adapter rings to ensure a centered arrangement of the drawbar in the support plate. The hydraulic cylinder itself in turn can have an adapter plate, which is designed as a pressure plate and configured such that it presses only on the outer ring of the wheel bearing to be pressed upon activation of the hydraulic cylinder. In that regard, a wheel bearing by means of this construction is also extremely easy pressed into the bearing bore of the bearing eye of an axle body.
    Also, the subject of DE 201 06 519 Ul shows a similar-acting construction, in which for pressing a wheel bearing in the corresponding bearing bore on the outer ring of the wheel bearing abstützendes pressure piece and in the surrounding area of the bearing seat or bearing eye supporting support plate is provided whose distance For example, can also be reduced by means of a pull spindle with pull nut or a hydraulic cylinder.
    All these wheel bearing tools have in common that a kind of pull rod, be it in the form of a piston rod of a hydraulic cylinder or a tension spindle, must be inserted through the wheel bearing and the axle component, on various support plates, pressure plates or plungers on the one hand a support on the axle itself and On the other hand, to be able to effect on the outer ring of the wheel bearing.
    Thus, with the cited prior art devices, only wheel bearings can be pressed into a bearing bore of an axle body or a bearing eye of an axle body, in which the pull rod or piston rod of the hydraulic cylinder is inserted through the wheel bearing and the axle body.
    ♦ · ♦ »• · * .3
    In newer axle designs, it has now become known that a wheel bearing is to be pressed together with an axially fixed and rotatably received wheel hub in a corresponding bearing bore. Since such a hub has a through hole with internal teeth only with driven axles and is normally closed when the axles are not driven, a tension spindle or a piston rod of a hydraulic cylinder can not pass through it for pressing the wheel bearing seated on the wheel hub into the bearing bore of the bearing eye be plugged. However, in order to be able to press in a wheel bearing in such a case, from DE 20 2005 003 450 Ul a device or a wheel bearing tool has become known, in which the abutment via corresponding tie rods, which are passed on the radially outwardly protruding hub flange, with the axle can be brought stationary in connection. To transmit the pressing forces of a pressing device on the einzupressende, provided with the wheel hub wheel bearing a pressure plate is provided in this article, which is introduced with an approximately semicircular recess in a space between the hub flange of the wheel hub and the wheel bearing. Since the support plate is fixedly arranged on the axle body, axial pressing forces can thus be applied via this pressing plate, in particular to the outer ring of the wheel bearing, via a corresponding pressing device, so that the wheel bearing can be pressed into the bearing bore of the axle body.
    In this construction according to DE 20 2005 003 450, the pressure plate is formed in two parts and forms a guide plate, which is associated with an additional holding plate, which is fixedly screwed to the guide plate. Both the guide plate and the holding plate each have a semicircular recess, which complement each other in the mounted state to an annular recess of the entire press plate. For axial support on the outer ring of the wheel bearing these two recesses form radially inwardly directed support flanges over which the pressure plate is axially supported on the outer ring of the wheel bearing. The guide plate in turn is slidably mounted on two of the support rods of the support plate, so that these support rods each form a kind of guide rod. Thus, this device or this pressing tool is extremely complicated to handle. First, the guide plate must be brought into the space between the hub flange and the wheel bearing or the outer ring of the wheel bearing
    • · · · · * * .4 * *. Arranged there, it can be assigned to the holding plate and, in order to form a uniform pressing plate, must be screwed to the guide plate. In this attached state, the wheel hub is then attached together with the wheel bearing on the bearing bore of the bearing eye, then the two guide rods for the pressure plate are inserted through corresponding guide holes of the guide plate therethrough. The guide rods are then fixed, for example, with appropriately arranged, radially projecting bearing eyes of the axle body engageable. Such bearing eyes can serve in the normal operation of the vehicle, for example for attachment of a caliper. Subsequently, the third support rod, for example, with the steering lever of the axle body are fixedly engaged. The two guide rods and the support rod are used for placing the support plate, which after the above "" Ansetzvorgang " fixedly connected to the two guide rods and the support rod. The support plate accommodates a hollow cylinder designed as a hydraulic cylinder, which has an axially adjustable in the pressing direction piston rod. If this piston rod is in its retracted state, a coupling bridge can now be brought into connection with the press plate applied to the wheel bearing. For this purpose, two corresponding connecting screws and two spacers are provided, which is adjustable by the spacers of the necessary distance between the Radlagerflansch and the coupling bridge. The coupling bridge has for coupling to the piston rod to a corresponding Aufhahmebohrung, which is provided with an internal thread, in which the piston rod is screwed accordingly. After this construction is attached in the manner described on the wheel hub together with the fixedly mounted on the wheel hub wheel bearing, corresponding pressing forces can now be applied to the coupling bridge over the hydraulic cylinder so that the wheel bearing on the press plate in the bearing bore of the bearing eye Axle body is pressed.

    Furthermore, it can be seen from FIG. 1 that, in the region of these two U-legs 6 and 7, a front-side support surface 20 or 21 is respectively provided with the two surface sections 18 and 19. With these support surfaces 20 and 21, the supplementary plate 3 can be brought into pressure connection. For this purpose, supplementary plate 3 has at its longitudinal edges in each case a Eingrißfssteg 22 and 23 respectively. • ♦ · · · · · · · · * · «* ··» f ····
    These engaging webs 22, 23 are offset relative to the supplementary plate 3 and accordingly limited on the inside by a respective guide surface 24 and 25 respectively. The distance A of these two guide surfaces 24 and 25 is adapted to the clear width of the two inner edges of the two U-legs 6 and 7 such that the supplementary plate 3 is fittingly inserted between the two U-legs 6 and 7. It can also be seen from FIG. 1 that the supplementary plate 3 has a semicircular recess 26 which forms a substantially circular opening in the installed state of the supplementary plate 3 on the pressure plate 2 together with the recess section 5 of the pressure plate 2. The supplementary plate 3 also has a flat rear side 27, which is connected to the inner edge 29 of the recess 26 via an obliquely curved surface section 28.
    Furthermore, it can be seen from FIG. 1 that in the upper end region the supplementary plate 3 has two laterally projecting stops 30 and 31, by which in particular the maximum insertion depth of the supplementary plate 3 into the recess 4 of the pressure plate 2 is defined.

In particular, it can be seen from FIG. 2 that in the surrounding area both of the recess section 5 or its inner edge 16 and the recess 26 of the supplementary plate 3 are respectively milled into an annular recess 32 or 33, so that between these two recesses 32 and 33 and the belonging inner edges 16 and 29 respectively an axially projecting ring portion 34 and 35 results. The recesses 32 and 33 form a circumferential receiving groove in the mounted state, so that a wheel bearing to be pressed in can be sunk into a correspondingly associated bearing eye of an axle body.
    Furthermore, it can be seen that the two countersunk support surfaces 20 and 21 extend approximately to the recess portion 5 and are bounded by an arcuate wall portion 36 and 37, respectively. In the assembled state engages in this wall portion 36 and 37, a corresponding arcuate end portion 38 and 39 of the two lateral engaging webs 22 and 23 of the supplementary plate 3 a fitting. Thus, the ffontseitige front surface 40 and the annular portion 35 form a interrupted by the recess 33 flat front end.
    Furthermore, it can be seen from FIG. 2 that the planar ring section 34 is sunk in the pressure plate 2 at the front. Thus, a correspondingly inclined wedge surface 45 extends to a recess 32 around a kind of circumferential annular rib 41 of the pressure plate 2. This shape is chosen according to the configuration of an axle body, so that the pressure plate 2 with little clearance between these axle and a einzupressendes wheel bearing is inserted.
    For this purpose, FIG. 3 shows the mounted state of the supplementary plate 3 in the pressure plate 2, which jointly form the pressure plate 1. It can be seen that the two ring sections 34 and 35 form a uniform circular pressing surface 42 which encloses a corresponding common opening 43 in full circumference. With this uniform pressing surface 42, the pressing plate 1 can be attached to a wheel bearing or its outer bearing ring and thus brought into pressure connection. The supplementary plate 3 is inserted between the two U-legs 6 and 7 and fits in the upper end of these two U-legs 6 and 7 with their laterally projecting stops 30 and 31 at. In this assembled state, the pressure plate 1 can now be brought about its two bearing eyes 8 and 9 with a pressing device in engagement. Whereupon, for fitting a wheel bearing arranged on a wheel hub, the pressure plate is first introduced into the intermediate space between the wheel bearing and the wheel hub flange of the wheel hub, and then the supplementary plate 3 is inserted between the two U legs 6 and 7, as can be seen from FIG ,
    It can be seen that the supplementary plate 3 with its two engagement webs 22 and 23 on the receiving side with the two support surfaces 20 and 21 of the pressure plate 2 is engaged. It can be provided in this area in the drawing not shown magnetic inserts, so that the supplementary plate 3 is held independently in this state attached to the support surfaces 20 and 21 in the region of the two U-legs 6 and 7. Further, from Fig. 4 nor the concrete shape of the inclined wedge surface 45 can be seen. As already mentioned above, press plate 1 from FIGS. 1 to 4 serves to press in a wheel bearing seated on a wheel hub into a corresponding bearing bore of a bearing housing of an axle body. • * * * * * * «* * *« «* · ·» «• I * * * * * * * * * * * * * * * * '* **' · "*
    5 shows, by way of example, an exploded perspective view of such an axle body 50 together with a wheel hub 51, on the shaft section 52 of which a wheel bearing 53 is received in an axially fixed manner. This wheel bearing 53 has a design-related distance to a radially projecting hub flange 54, so that between this Hub Hub 54 and the wheel bearing 53, a corresponding gap 55 is formed. Furthermore, it can be seen from FIG. 5 that the wheel hub flange 54 is provided with a plurality of through holes 56 distributed uniformly around the circumference, which in the normal operating state of the wheel hub 51 serve for fixed mounting of, for example, a brake disk together with a corresponding wheel of a motor vehicle.
    The axle body 50 has in the illustrated embodiment, a radially projecting lever 57, on which in the operating state usually the tie rod of the steering of a motor vehicle is pivotally mounted. Accordingly, this deflection lever 57 is provided with a through hole 58.
    Opposite this deflection lever 57, the axle body 50 forms two radially projecting bearing plates 59 and 60, which are respectively provided with a through-bore 61 and 62, respectively. These through holes 61 and 62 may also be formed as a through thread and are used in normal operation for fixed recording, for example, a brake caliper of a disc brake.
    In the upper end region of the axle body 50 forms a mounting block 63, via which the axle body 50 can be coupled for example with a spring damper strut of a motor vehicle axle. In the lower end region of the axle body 50 an inwardly projecting mounting bar 64 is provided, via the mounting hole 65 of the axle body 50, for example, with a lower arm of a motor vehicle axle is pivotally brought into connection.
    Further, the axle body 50 forms a central bearing housing 66, in the center of which a bearing bore 67 is provided. This bearing bore 67 is used in normal operation for receiving the wheel bearing 53, wherein the pressure plate 1 according to the invention for pressing in this wheel bearing 53 together with the wheel hub 51 mounted therein serves.
    For this purpose, the pressure plate 2 can be used together with the supplementary plate 3 in the intermediate space 55 between the wheel hub flange 54 and the wheel bearing 53. Thus, the * * * · ··· · t * · · · · · · · · · · · · · · · · · · · · ··············································· ...

    6 shows schematically a vertical sectional view of the wheel hub 51 with the attached pressing plate 1. From FIG. 6 it can be seen that the wheel bearing 53 is placed on the shaft section 52 of the wheel hub 51. Between the wheel bearing 53 and the radially projecting hub flange 54 of the space 55 described in FIG. 5 is clearly visible. In this space 55, the pressure plate 2 protrudes with its ring portion 34, which in turn abuts the wheel bearing 53 at the end. The supplementary plate 3 is inserted into the pressure plate 2 and is also at its end with its ring portion 35 on the wheel bearing 53 at. In this case, as can be seen from FIG. 6, these two ring sections 34 and 35 are located precisely in this intermediate space 55 between the wheel bearing 53 and the radially projecting hub flange 54.
    It can also be seen from FIG. 6 that centering pins 68 and 69 are screwed into two of the through threads 56. These centering pins 68, 69 are designed such that they engage with a centering pin 70 (shown only for the centering pin 69) in one of the wells described in Fig. 1 fits. From Fig. 6 it can be seen that the centering pin 70 engages in the lower recess 14 of the pressure plate 2. Accordingly, the centering pin 70, not visible in FIG. 6, of the centering pin 68 engages in the recess 15. For the complete centered attachment another, not visible in Fig. 6 centering pin is provided, which engages with its corresponding centering pin in the recess 13 of the pressure plate 2 of FIG. This is by these centering pins 68, 69 by their multiple arrangement and by their proper engagement with their centering in the corresponding recesses 13, 14 and 15, a concentric alignment of the pressure plate 2 with its semicircular recess portion 5 on the Radlagemabe and thus also with respect to the wheel bearing 53 reached. After insertion of the supplementary plate 3 are thus on the wheel bearing due to the frontal conditioning of this press plate 1 with its peripheral pressing surface 42 on the wheel bearing 53 corresponding axial pressing forces on the wheel bearing 53 exercisable so that this in the bearing bore 67 of the bearing housing 66 of FIG. 5 of Achskörpers 50 can be pressed. Accordingly, a pressing device is provided for this press-fitting operation, which is engageable on the one hand with the pressing plate 1 and on the other hand with the axle body 50. For this purpose, the following drawing figures show by way of example a possible embodiment variant of such a pressing device.
    Thus, FIG. 7 shows, by way of example, a perspective view of a pressing device 75 in its state fixed on the axle body 50. This pressing device 75 is attached to the axle body 50 via a total of three tie rods 76, 77 and 78. The pull rod 76 has a mounting head 79, via which it is fixedly mounted on the deflection lever 57 via a corresponding fastening screw 80. The two tie rods 77 and 78 are fastened via two fastening screws 81 and 82 to the two bearing brackets 59 and 60 of the axle body 50. To stabilize these bearing plates 59 and 60, a strut 83 is provided in the illustrated embodiment on the back of these bearing brackets 59, 60, which is penetrated by the two fastening screws 81 and 82.
    At a distance to the axle 50 and, accordingly, at the opposite ends of the three tie rods 76, 77 and 78, a support plate 84 is provided which has a plurality of slot-like apertures 85, 86 and 87, with which the tie rods 76, 77 and 78 are fixedly engaged , On the back can be appropriate Zugmuttem (not visible in the drawing) screwed onto the tie rods 76, 77 and 78, so that the support plate 84 is stationary with the tie rods 76,77 and 78 is engaged.
    Furthermore, it can be seen from FIG. 7 that the support plate 84 has a central receiving bore 88, which is provided with an internal thread (not shown) and serves to receive a hydraulic cylinder 89. This hydraulic cylinder 89 is referred to as a so-called " hollow piston cylinder " formed and has a piston rod 90, which in turn is provided with an external thread 91. About this external thread 91, the piston rod 90 in the direction of the double arrow 92 relative to the hydraulic cylinder 89 is adjustable. Furthermore, this piston rod is provided with respect to the axle body 50 with a coupling element 93, via which the piston rod 90 can be indirectly connected to the pressure plate 1 from FIGS. 1 to 3. In the position of the pressing device 75 fixedly positioned on the axle body 50 shown in FIG. 7, the longitudinal center axis 94 of the piston rod 90 is concentric with the longitudinal center axis 95 of the bearing bore 67 of the axle body 50. Thus, axial pressing forces are concentric with the bearing bore 67 on the bearing bore 67 by the piston rod 90 Piston rod 90 indirectly applied pressure plate 1 of FIGS. 1 to 3 can be applied.
    For indirect attachment of the press plate 1, the bearing eyes 8 and 9 described with reference to FIG. 1 serve with their respective through holes having through holes 10 and 11th
    For this purpose, FIG. 8 shows a perspective view of the pressure plate 2 in its state fixedly attached to a crosspiece 100. The pressure plate 2 is connected via two drawbars 101 and 102 with the cross-beam 100 fixed in connection. In this case, the distance between the cross-beam 100 and the pressure plate 2 is selected such that between these the wheel hub flange 54 of the wheel hub 51 of FIGS. 5 and 6 is receivable. Furthermore, FIG. 8 shows that the cross-beam 100 has a central coupling element 103, which is arranged with its longitudinal central axis 104 concentric with the circular-arc-shaped recess section 5 of the pressure plate 2.
    This coupling element 103 can be brought into pressure connection with the coupling element 93 of the piston rod 90, for which purpose the coupling element 93 can be fixedly coupled via a threaded connection to the coupling element 103. The clear distance of the two push rods 101 and 102 is selected so that the wheel hub flange 54 of the wheel hub 51 of FIG. 5 finds between these place.
    The pressure plate 2 can be used together with the wheel bearing 53 provided with the wheel hub 51 in the attached to the axle 50 pressing device 75.
    Fig. 9 shows a perspective view of this pressing device 75 with the recorded cross-beam 100, which in turn aufhimmt the wheel hub 51 together with the attached wheel bearing 53 on the press plate 1. It can be seen that the pressure plate 2 and the supplementary plate 3 together with the suggestively recognizable Radnabenflansch 54 of the hub 51 between the tie rods 76, 77 and 78 find space, the tie rod 77 in Fig. 9 is not visible. In this mounted position of the wheel bearing 53 on the bearing bore 67 of the bearing housing 66 shown in FIG. 9, the piston rod 90 is in its " retracted " Initial state. By activating the hydraulic cylinder 89, the piston rod 90 is moved in the direction of the arrow 105, so that the cross-beam 100 and the press plate 1 are moved in the same direction. With this adjusting movement, the wheel bearing 53 is thus pressed into the bearing bore 67 of the bearing housing 66.
    Due to the two-part design of the press plate 1 with its pressure plate 2 and the supplementary plate 3, the wheel hub 51 can be brought together with the wheel bearing 53 in a simple manner with the press plate 1 in engagement. Due to the special configuration of the crossbar 100 with its two push rods 101 and 102 (FIG. 8), this complete unit, as shown in FIG. 9, can be brought into engagement with the piston rod 90 of the hydraulic cylinder 89 in a simple manner. For this purpose, this unit must only be brought concentrically aligned with the bearing bore 67 aligned with the piston rod 90 via the cross-beam 100 in a screw connection. As a result of this connection between the piston rod 90 and the cross-beam 100, optimum alignment of the wheel bearing 53 with the bearing bore 67 of the bearing housing 66 of the axle body 50 is thus inevitably achieved. Due to the concentric alignment of the piston rod 90 to the bearing bore 67 concentric press-in forces in the direction of arrow 105 can thus be transmitted via the press plate 1 on the outer ring of the wheel bearing 53 via the crossbeam 100, so that it is precisely pressed into the bearing bore 67 without tilting.
    The embodiment of the two-part pressure plate 1 according to the invention thus makes possible an extremely simple application of the unit consisting of the pressure plate 1 and the crosspiece 100 mounted on the pressure plate 1 via the push rods 101 and 102 on a wheel bearing 53 seated on a wheel hub 51. This unit can then be used in a simple manner in the already fixed to the axle beam 50 pressing device 75 and the wheel bearing 53 are pressed into the bearing bore 67 of the axle body 50.
