Definitions

  • the invention relates to a wheel bearing arrangement with a designed as angular contact ball bearings or tapered roller bearing, which comprises between a torsionally rigid bearing part and connected to a Radlagerflansch rotatable bearing part rolling elements, wherein the Radlagerflansch facing the wheel bearing, is formed with a radially extending contact portion and the rotatable bearing part has a rolling body track, to which in the direction of the Radlagerflansches an axially extending, a slinger receiving, receiving portion abuts.
  • the spin plate has a first, substantially axially extending portion and a second, substantially radially extending portion, which, connected by an intermediate portion, are arranged at an angle to each other. With the intermediate portion of the first portion and the second portion are each connected by a bending edge.
  • the seals used may cooperate with a spin plate made of formed sheet metal.
  • the centrifugal plate connected to a rotating wheel hub or a wheel bearing flange can, together with another in a nem stationary part of the suspension arranged sheet metal ring form an additional seal labyrinth.
  • sealing lips run at least one sealing ring in the axial or radial direction and are slidably guided on the centrifugal plate.
  • the abovementioned components of the seal can also be an integral part of a sealing cassette in which the sealing lips are defined axially prestressed.
  • Axial wheel flange side the opening between the rotating partners of the wheel bearing, due to the immediately adjacent wheel flange, directed radially outward and very easy to reach for splashing.
  • a centrifugal plate is mounted adjacent to the wheel flange before installation of the wheel bearing on the wheel hub.
  • the skid plate is made of a higher quality material than the wheel flange, such as a stainless steel.
  • the spin plate may also consist of a steel sheet whose surface is treated, for example galvanized or coated.
  • Slippage of the slinger can be triggered by vibration, sustained vibration loads or other causes, whereby the slinger on the outer surface axially approaches the rolling elements and damage them in contact. This leads to a failure of the wheel bearing.
  • a wheel bearing arrangement is known from DE 10 2013 218 635 A1, comprising a wheel bearing embodied as an angular contact ball bearing or tapered roller bearing which comprises rolling elements guided between a torsionally rigid bearing part and a rotatable bearing part connected to a wheel bearing flange.

  • the centrifugal plate is in contact with the contact area of the wheel flange on the one hand, in contact with the surface or surface.
  • the second portion of the centrifugal plate is pressed onto the receiving portion of the torsionally rigid bearing part.
  • the first section of the centrifugal plate locks at the end on a radially extending, circumferential step, which is arranged adjacent to the rolling body track. For this purpose, the first section must be pressed over the step when pressing with an assembly tool, so that a locking is achieved.
  • the problem may arise that the first portion of the spin plate is not completely pressed during pressing over the step, so that the spin plate in the axial direction is not sufficiently secured or there may be an axial play, which is due to manufacturing tolerances, what can lead to a gap.

  • the groove in the area of the bending edge enables the overpressing, so that the pressing force of the mounting tool acting on the intermediate section effects a compression of the bending edge in the direction of the groove.
  • the stiffness of the centrifugal plate is greatest, so that in this area the highest contact pressure to the rotatable bearing part is present. Forces introduced into the sluice plate by microvibrations would have to build up a voltage in the region of the bending edge in order to cause the bending edge to spring back.

  • the first section of the skid plate for axial securing can additionally be supported on a, in particular circumferential, projection.
  • the intermediate section of the centrifugal plate can preferably be designed as a contact surface intended for a mounting tool. This allows the take-up of the slinger by an assembly tool for automated assembly to press the slinger on the receiving portion until an axial position is reached, in which the bending edge springs into the groove of the receiving portion.
