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 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.

Accordingly, the sleeve portion 30 of the spacer sleeve 5 is formed axially shorter than the sleeve portions 31 of each of the support members 88, 89 and 90 associated spacer sleeves 6.
  • Fig. 9 shows the sectional view of the axle body 80 Fig. 8 with a fully assembled device 115 in section. It is in the representation of the Fig. 9 the bearing plate 1 off Fig. 1 attached to the axle 80 and, as already to Fig. 8 described, fixed mounted. Furthermore, the support cylinder 32 is arranged on the bearing plate 1, wherein the two guide pins 33 and 34 are inserted into the respectively associated fitting holes 24 and 25 of the bearing plate 1 fitting. In this state, the support cylinder 32 is thus secured on the bearing plate 1 via the guide pins 33 and 34 before the further assembly of the support plate 36 and the hydraulic cylinder 50.
  • Fig. 9 recognizable that the support plate 36 is inserted with its centering projection 38 fits into the support cylinder 32.
  • the coupling bushing 56 is screwed onto the mounting thread 55 of the hydraulic cylinder 50 and inserted with its mounting ring 58 in the receiving bore 37 of the support plate 36.
  • Out Fig. 9 is also the above-mentioned O-ring 116 recognizable.
  • the tension nut 60 is delivered so far that the support ring 71 abuts with its support web 75, for example, the rear side of the wheel bearing housing 100 under slight bias.
  • the lifting piston 53 moves in the direction of the arrow 54, so that inevitably the wheel bearing housing 100 is pulled out of the axle body 80 or its receiving bore 82.
  • 115 extremely high tensile forces for disassembling the wheel bearing housing 100 can be applied by means of the device 115 according to the invention.
  • hydraulic cylinders 50 can be used here, which can apply an axial force of up to 10 t and more.
  • these high axial forces for example via the support members 87, 88, 89 and 90 in the axle body 80 can be introduced without any damage may occur here.
  • results from the orientation of the bearing plate 1 transverse to the bearing axis 86 an absolutely concentric introduction of the tensile forces in the wheel bearing housing 100, so that tilting during the extraction process of the wheel bearing housing 100 is safely excluded.
  • Fig. 10 shows a partial section with an attached device 115/1, which is mounted on the axle body 80 using the bearing plate 1/1.
  • this bearing plate 1/1 is in accordance with the Fig. 4 the support cylinder 32 without the guide pins 33 and 34 used. Due to the provided recess 46 of the support cylinder 32 is guided in this recess 46 fitting.
  • Fig. 10 an embodiment in which the zu Fig. 6 described wheel carrier 107 is still firmly seated in the wheel bearing 102. It can be seen that the dimensions of the support cylinder 32 are selected such that it can be pushed over the mounting flange 108 of the wheel carrier 107 with little play. In this embodiment, therefore, the mounting flange 108 of the wheel carrier 107 serves as an additional safeguard for the support cylinder 32, so that it is secured to the axle body 80 before mounting the support plate 36.
  • mounting screws 42 and 43 in their countersunk heads 44th and 45 used for the fixed mounting of the bearing plate 1 or 1/1 on the other through holes 11 to 15 to Fig. 3 described mounting screws 42 and 43 in their countersunk heads 44th and 45 used.
  • Fig. 10 in dashed lines, for example, the through holes 11 and 15 recognizable. Since the countersunk heads 44 and 45 of the mounting screws 42 and 43 from Fig. 3 sunk in the depressions 16 and 20, a flat application of the support cylinder 32 with its end face 35 on the bearing plate 1 and 1/1 is also possible.
