Definitions

  • Bearing unit preferably wheel bearing unit for a motor vehicle, and method for producing a storage unit
  • the invention relates to a bearing unit, preferably a wheel bearing unit for a motor vehicle, comprising a hub with a wheel-side hub flange on which a skewed roller bearing is arranged with at least one inner ring and one outer ring. Furthermore, the invention relates to a method for mounting such a bearing unit, by means of a clamping force on the bearing unit performing device.
  • Wheel bearings are highly stressed parts especially for suspension on the chassis of a motor vehicle, which must withstand a wide variety of operating stresses.
  • An important component of the overall composite wheel bearing are its bearing inner rings, which are fixed axially after heat treatments and cutting steps with a correspondingly high clamping force - depending on the bearing size 50KN to 120KN.
  • Known devices and methods for adjusting such axial Clamping force is a bracing of wheel flange with joint bell, a nut on the wheel flange or a Wälznietbund generated by means of a Wälznietfracs using a Wälznietvenez.
  • Such Wälznietbund is generated by cold deformation by means of rolling rivets at the hub end of the wheel bearing, which forms there an outwardly curved bead for fixing the inner ring to the hub.
  • DE 43 39 847 C2 shows a generic wheel bearing unit for motor vehicles, consisting of a hub and a Schrägnachlzlager, in which at least one inner ring is axially fixed by a generated by means of a plastic cold deformation by means of rolling rivets in a Wälznietmaschine, integrally formed at the hub end bead.
  • the bead seen in cross-section, has a curvature which extends to the outer periphery and is inclined to the inner ring.
  • the inner ring clamping force are of crucial importance to the extent of the supernatant of the initially undeformed bead, the inner ring Kantenverkürzungsgeometrie, the tool profile for the axial bead outer shape and the Wälznietkraft. Tight tolerances and exact dimensions are therefore required.
  • the force-displacement curve is determined and compared with predetermined values.
  • the deviation is introduced as a controlled variable into a force-controlled forming machine, for example a tumbling press.
  • the invention has for its object to provide a bearing unit, preferably a wheel bearing unit for a motor vehicle, the type mentioned and a manufacturing method of such a storage unit, which provides a precise and generates little variance prone clamping force, expansion problems, such as deformations and stresses as in known Wälznietein whatsoever, avoids and are inexpensive to produce and operable.
  • the invention is based on the finding that cold deformations of thick-walled cross-sections at relatively small diameters (ratio of wall thickness to diameter bore 0.2 to 0.08), in particular by Wälznietvon and Wälznietein whatsoever, usually lead to unwanted additional radial deformations and stresses on ⁇ lzniet Municipalen inner ring board which can adversely affect the function and reliability of the storage unit.
  • the invention is therefore based on a bearing unit, preferably a wheel bearing unit for a motor vehicle, comprising a hub with a wheel-side mounting flange, on which a skewed roller bearing with at least one inner ring and an outer ring are arranged.
  • a bearing unit preferably a wheel bearing unit for a motor vehicle, comprising a hub with a wheel-side mounting flange, on which a skewed roller bearing with at least one inner ring and an outer ring are arranged.
  • the fastening flange of the opposite end of the hub is integrally connected to a flange, which braces at least the inner ring with the hub.
  • the at least one inner ring of the angular rolling bearing is connected by the flange without additional radial deformations and / or stresses on the flanschring Technologyen inner ring with the hub of the bearing unit.
  • the solution according to the invention can be used in wheel bearings of all types for motor vehicles, in particular in those wheel bearings which are to have a preset inner ring clamping force, without the need for further modifications or additional expenditures on the wheel bearing.
  • the end of the hub opposite the fastening flange is welded to the flange ring.
  • the mounting flange opposite end of the hub is connected to the flange by means of laser welding.
  • the laser welding method uses a non-contact, thermally less stressful and exact welding method, which has a low radiation divergence with high radiant energy and good focusability and is not subject to wear as a tool.
  • the invention is based on a method for producing a bearing unit, preferably a wheel bearing unit for a motor vehicle, comprising a hub with a wheel-side mounting flange on which a skew roller bearing is arranged with at least one inner ring and one outer ring, by means of a clamping force on the bearing unit, in particular to the at least one inner ring and / or the hub of the bearing unit, performing device.
  • a bearing unit preferably a wheel bearing unit for a motor vehicle, comprising a hub with a wheel-side mounting flange on which a skew roller bearing is arranged with at least one inner ring and one outer ring, by means of a clamping force on the bearing unit, in particular to the at least one inner ring and / or the hub of the bearing unit, performing device.
  • the invention also allows the use of two symmetrical identical inner rings - in the event that two inner rings are arranged for the angular rolling bearing - because a geometric edge shortening can be dimensioned only for strength requirements on the side of the mounting flange.
  • the flanschrDeutsch solvede edge shortening could also be made very small to reduce a bending moment due to the axial clamping force, in contrast to Wälznietein founded where the formation of the edge shortening has a direct impact on the forming behavior of the hub end formed bead.
  • the inventive method further allows the setting of any defined clamping force on the bearing unit or on the at least one inner ring without additional radial expansion problems, as they usually occur in the known WälznieteinRIC, for example, the occurrence of large variations due to the large Umformvarianz.
  • a precise adherence to the clamping force is made possible by a precisely metered pressing force.
  • the clamping force exerted by the device is withdrawn, wherein the bearing unit, in particular the inner ring, in particular by an amount of Flanschteilfederung or the Naben Wegfederkraftanteils and / or the Flanschring Wegfederkraftanteils relaxed in the desired bearing clamping force.
  • the end of the hub opposite the fastening flange is welded to the flange ring.
  • the mounting flange is connected to opposite end of the hub with the flange by means of laser welding. In this case, no deformations and / or tensions occur in the application of the laser welding process.
  • the wheel bearing unit 1 has a hub 2 with a wheel-side mounting flange 3, to which by means of connecting elements 4, for example screws, an unrepresented friction body, namely a brake disc and a wheel rim, are attached.
  • the hub 2 is, as usual for driven axles, via an internal toothing
  • hubs for non-driven axles is the Hub inside without elements for the torque transmission and can be solid or fully formed with recesses.
  • a double-row oblique roller bearing 6 which has a two-part inner ring 7 and an outer ring 8, between which two rings of spherical rolling elements 9 are arranged.
  • the attachment flange 3 opposite end 10 of the hub 2 is integrally connected to a flange 11, namely by means of welding and preferably by laser welding to the designated 12 inner circumference of the flange 11, so that the adjacent inner ring 7 with the hub 2 by a biasing force is tense.
  • this wheel bearing unit 1 is carried out by applying a force acting on the wheel bearing unit 1 clamping force F, which is applied by the device 13 shown schematically.
  • the montfederkraftanteil determined from the known spring characteristics of the hub 2 and the flange 11, which may be determined, for example, in the process for the production process.
  • the flange ring 11 is connected to the end 10 of the hub 2 opposite the fastening flange 3 by a welding operation, preferably by laser welding, in a material-locking manner and free of additional radial widenings or stresses in the inner rings 7.
  • a welding operation preferably by laser welding
  • the force exerted by the device 13 on the wheel bearing inner rings 7 clamping force F is withdrawn.
  • the wheel bearing inner rings 7 relax by the amount of springback of the hub 2 and the flange 11 in the desired Radlagerklemmkraft.
