Definitions

  • the present invention relates to a device for the radial support and axially displaceable mounting of an annular disc on a thus non-rotatably connected hub, in particular a brake disc on a hub of a commercial vehicle.
  • an interlocking toothing is known, which is provided on the one hand on the brake disc and on the other hand on the wheel hub and which is designed so that an axial relative movement in the sense of a Mikroverschiebung between the brake disc and the fixed hub possible is.
  • micro-displacement is meant that only the working stroke of the brake is bridged, but not the full wear path of the pads.
  • the present invention is therefore the object of further developing a device of the generic type so that it remains permanently functional and can be produced with low production costs.
  • the use of the new device is not limited to the use in the brake discs / hubs range of a commercial vehicle, but is everywhere used where a radial support and at the same time an axial micro displacement of two
  • Components are required to each other at high thermal and mechanical stress.
  • the new device is characterized by its robustness, so that it is insensitive to pollution caused by brake pad dust, salt water or other dirt, as well as against extreme external influences, such as the high temperatures due to the frictional heat generated during braking.
  • the device forming a bearing is partially open at both ends, so that dirt can penetrate, however, the relative axial displacement of the outer and inner ring to each other due to the required micro-displacement is very low, so that penetrated dirt by the given high Hertzian pressure so to speak is pushed away and the micro-displacement is thus permanently guaranteed. Due to the mentioned low axial paths as well as the small number of displacement movements compared to conventional bearings, the function of the device is not endangered by a potentially abrasive effect of the dirt particles.
  • the rolling elements as balls or Wälzrollen, preferably cylindrical Wälzrollen form, which are supported on a respective tangentially oriented running surface of both the outer and inner ring, the central axes of the Wälzrollen course also tangentially aligned.
  • Each tread is cylindrical in the axial direction of the outer or inner ring to one side to the outer edge of balls and level with Wälzrollen and formed on the other side as a böschungsGermanr stop which forms a Endbegrren- tion for the running surface of the ball or Wälzrolle ,
  • the stops of the running surfaces are provided on the outer and inner ring respectively on opposite sides, so that a stop of the inner ring of the extent level outlet of the corresponding running surface of the outer ring is assigned.
  • the rolling elements are preferably distributed at the same angular distance over the circumference and preferably formed equal in shape and dimension.
  • these may be made of a non-corrosive metal, preferably a stainless steel as well as the rolling elements.
  • the rolling elements, especially the Wälzrollen or balls are available as commercially available series parts very inexpensive.
  • the new device also represents an optimization over the prior art in terms of manufacturing costs. The products resulting from the braking friction relatively high temperatures remain by * said choice of material without affecting the functionality of the device, so that the lifetime total to the desired extent is improved.
  • FIG. 1 shows a device according to the invention mounted in a brake disk / hub connection in a sectioned section;
  • FIG. 2 shows the device according to FIG. 1 in another sectional plane
  • Figure 3 is a partial section of the device in a perspective view
  • Figure 4 shows the device also in a perspective view
  • Figure 5 shows the device as a detail in a cross-sectional view.
  • a partial section of a disc brake for a commercial vehicle which has a brake disc 1, which is secured against rotation and axially mounted on a wheel hub 2 micro-displaceable.
  • an axially deflectable disc 15 and a device in the form of a bearing 4 is provided which simultaneously enables the displaceability of the brake disc 1 via the working stroke.
  • This bearing 4 consists of a fixedly connected to the brake disc 1 outer ring 5, an attached to the hub 2 inner ring 6 and rolling elements 7 in the form of Wälzrollen, which are arranged between the outer and the inner ring 5, 6 and to which these each support.
  • FIG. 2 shows a section through a plane in which a through hole 13 is arranged, while the figure 1 shows a section through a plane in the area next to a through hole 13, in which a rolling element 7 is arranged.
  • the rolling elements 7 are formed as cylindrical Wälzrollen, with their rolling axes extend in the tangential direction.
  • the rolling elements 7 are on running surfaces 11 of the outer and inner ring 5, 6, which are flat in the tangential direction and whose corresponding dimension corresponds to the length of the respective rolling element 7, so that it is laterally secured against slipping.
  • the outer and inner rings 5, 6 are arranged relative to one another in such a way that the respective stops 12 extend in the region of the opposite end faces of the bearing 4, each stop 12 ending below the central axis of the rolling element 7 ,
  • cylindrical Wälzkörpez ⁇ »7 may also be provided barrel-shaped or spherical, in which case, however, the production of the tread is a little more expensive.
  • the inner ring 6 is held axially secured to the wheel hub 2 on the one hand by a molded shoulder 14 and on the other hand, a recessed into the wheel hub 2

Abstract

L'invention concerne un dispositif permettant de soutenir dans le sens radial et de loger de manière coulissante dans le sens axial un disque annulaire sur un moyeu auquel il est relié, bloqué en rotation, en particulier un disque de frein (1) sur un moyeu de roue (2) de véhicule utilitaire. Ledit dispositif est conçu de manière à présenter une bague extérieure (5) reliée au disque et une bague intérieure (6) reliée au moyeu, ainsi que des corps de roulement (7) disposés entre, sur lesquels la bague extérieure (5) et la bague intérieure (6) s'appuient de manière à se déplacer l'une par rapport à l'autre dans le sens axial.
