Definitions

  • the invention relates to a differential bearing arrangement for mounting a differential cage in a axle bridge of a motor vehicle axle.
  • a generic differential bearing arrangement is known for example from DE 2006 012 342 A1.
  • This comprises an axle drive housing having a first section and a second section, which are separated from one another by a fastening ring for fastening the final drive housing to an axle bridge of a vehicle axle.
  • At least a two-part bearing mounting arrangement is mounted on the first portion of the axle drive housing, which accommodates the differential carrier at least indirectly.
  • the bearing receiving arrangement consists of a one-piece bearing with the final drive housing bearing receiving element and a bearing bracket, which is fixedly connected to at least one fastening screw with the bearing receiving element of the final drive housing.
  • connection of the bearing bracket with the axle drive housing is usually designed such that a screw head of the fastening screw rests against the bearing bracket and a cylindrical screw body of the fastening screw is performed by a through hole made in the bearing bracket and engages in an executed in the bearing receiving element of the final drive housing bore, which with an internal thread is provided.
  • the bearing receiving arrangement has a bearing receiving opening for receiving a differential bearing.
  • the bearing receiving opening is partially carried out in the bearing receiving element of the drive housing and partially in the bearing bracket, so that the assembly of these two elements creates a complete bearing receiving opening for receiving a differential bearing.
  • the components, the bearing receiving element and the bearing bracket In order to ensure a required high accuracy of the bearing receiving opening, the components, the bearing receiving element and the bearing bracket, must be assembled first and then processed together. The mating parts, the bearing support element and the bearing bracket, must then be disassembled and paired delivered for final assembly of the axle.
  • This assembly order which must be strictly adhered to, means a high production cost and is therefore associated with high production costs.
  • Object of the present invention is therefore to provide a differential bearing assembly for supporting a differential cage in which the cost of manufacturing and assembly, as the installation costs are reduced.
  • bearing receiving element is designed as a separate, one-piece component, which is fixedly connected by means of at least one fastening means with the final drive housing and wherein the bearing receiving element thereon carried out gerager opening, for receiving a differential bearing for has the differential carrier.
  • the bearing receiving aperture of the bearing receiving member can be processed independently of the final drive housing. A confusion of a bearing receiving components forming is excluded.
  • the bearing receiving element comprises a receiving portion and an adjoining attachment portion.
  • the bearing receiving opening is designed in the receiving portion of the bearing receiving element.
  • the attachment portion includes at least one attachment opening for the attachment.
  • the bearing receiving member can be connected in a simple manner by means of a fastener with the final drive housing.
  • the bearing receiving element can, as shown in a further advantageous embodiment, come in a mounted differential bearing assembly with its attachment portion directly to the final drive housing to the plant.
  • the bearing receiving element may be designed so that is arranged at a mounted differential bearing assembly of the mounting portion of the bearing receiving element between the axle drive and the receiving portion of the bearing receiving member.
  • the Differenzialla- geranssen comprises at least one positioning pin which defines a mounting position of the bearing bracket relative to the final drive housing.
  • the positioning bolt can be designed both in one piece with the bearing bracket and also in one piece with the axle drive housing.

  • the drive housing can have at least one second recess for receiving the positioning bolt.
  • Differenziallageranord- tion of the bearing bracket and the drive housing each have a recess for receiving the positioning pin.
  • the bearing bracket and the axle drive housing are in this case aligned with each other so that the first recess of the bearing bracket and the second recess of the final drive housing overlap each other and that the separately executed positioning pin is disposed within the two recesses and thus determines the position of the bearing bracket to the final drive housing.

  • FIG 3 is a perspective view of an exemplary embodiment of a differential bearing assembly according to claim 1.
  • FIG. 1 shows a part of an axle bridge 22 of a vehicle axle with a differential bearing arrangement 1 according to the prior art.
  • This comprises an axle drive housing 2 with a first section 3 and a second section 4.

  • the bearing receiving arrangement 7 engages in each case one, each on one side of a differential cage 17 arranged differential bearing 18 and thus receives the differential carrier 17 at least indirectly.
  • FIG. 2 shows the bearing receiving arrangement 7 even more clearly.
  • FIG. 2 also clearly shows in FIG. 2 that the bearing receiving arrangement 7 consists of a bearing receiving element 8, which is formed integrally with the final drive housing 2, and a bearing bracket 6, FIG. which is firmly connected by means of fastening screws 11 with the bearing receiving element 8 of the final drive housing 2.
  • a differential bearing assembly 1 according to claim 1 is shown in perspective. This comprises an axle drive housing 2, as well as at least one bearing receiving element 8, which is fixedly connected to the axle drive housing 2 by means of at least one fastening means 9.
