Definitions

  • the invention relates to an axle bridge for a driven motor vehicle axle according to claim 1.
  • a generic axle bridge is known for example from DE2006 012 342 A1.
  • the published patent publication discloses an axle bridge which is connected to a differential bearing arrangement.
  • the differential bearing arrangement comprises a fastening ring which rests against the axle bridge and is fixed to the axle bridge with the aid of a plurality of fastening bolts.
  • the differential bearing arrangement comprises a first and a second fastening element which receive at least indirectly via a first and a second differential bearing a differential carrier and supported radially and axially.
  • the differential cage is arranged inside the Achs viteninnenraumes the axle bridge.
  • the fasteners of the differential bearing assembly are based on the abutment sections, which are arranged within the Achs viteninnenraumes from. This prevents a bending and thus a change in the bearing adjustment and the load.
  • the object of the present invention is therefore to provide an axle bridge, which overcomes the disadvantages of the prior art.
  • the mounting positions of the differential bearing arrangement may differ in that a second mounting position is rotated relative to a first mounting position, for example about an axis of rotation of the differential bearing assembly.
  • the rotation can according to a further advantageous embodiment have a size of 180 degrees.
  • the differential bearing arrangement may be designed so that its fastening elements, which are provided for at least indirect attachment of a differential cage and which are supported on the abutment sections in Achs viteninnenraum be designed to be different in size, as it is a further advantageous Design variant provides.
  • the abutment sections are designed stepwise with each other as each have at least two different degrees projecting into the Achsmaschineninnenraum stages.
  • at least one contact surface can be designed to support the fastening element of the differential bearing arrangement.
  • These can be mounted, for example, along different sized concentrically arranged imaginary bearing circuits. This has the advantage that a greater freedom of execution is made possible for the entire axle bridge.
  • the different plant circuits can be implemented in the Achsmaschine in the form of a stepped processing.
  • the differential bearing arrangement remains rotatable within the axle bridge interior and only one finished part variant of the axle bridge is required to produce different variants of a motor vehicle axle.
  • Fig. 1 a schematic representation of a motor vehicle, comprising a motor vehicle axle with a Achsmaschine according to claim 1;
  • FIG. 2 is a perspective view of an exemplary embodiment of an axle bridge according to claim 1;
  • FIG. 3 shows a further illustration of an axle bridge according to FIG. 2;
  • FIG. 4 is a partial sectional view of another exemplary embodiment of an axle according to claim 1, with a mounted thereon differential bearing assembly in a possible first mounting position.
  • FIG. 5 is a partial sectional view of another exemplary embodiment of a Achsmaschine according to claim 1, mounted thereon with a differential bearing assembly in a possible second mounting position.
  • Fig. 1 shows schematically a motor vehicle 17 with a motor vehicle axle 2 and a axle 1 which receives a differential 19 in a differential carrier 18.
  • This motor vehicle 17 comprises a motor vehicle engine 20 and a motor vehicle transmission 21 in operative connection with the motor vehicle engine 20.
  • the motor vehicle transmission 21 is operatively connected at least indirectly to at least one drive component 22 with the differential cage 18.
  • the torque provided by the motor vehicle engine 20 is transmitted to the motor vehicle wheels 23 via the motor vehicle transmission 21 and at least one drive component 22 via the differential 19, which is arranged in the axle box 1 in the differential carrier 18.
  • the contact sections 5, 6 are designed to support a differential bearing assembly 4, not shown here.
  • the contact sections 5, 6 are step-shaped, each with two stages 11, 12 executed, wherein the steps protrude different degrees in the Achs viteninnenraum 3.
  • the steps each have a contact surface 13, 14 for supporting a fastening element 9, 10, not shown here, of a differential bearing arrangement 4.
  • the abutment surface 13 is assigned to the step 11 and the abutment surface 14 is assigned to the step 12 of each abutment section 5, 6, which is visibly depicted here.
  • the embodiment variant shown in FIG. 2 represents only one possible embodiment variant and certainly can not be regarded as the only possible embodiment variant for the present invention.
  • more than just two abutment sections, more steps on the respective abutment section 5, 6, 7, 8 or even more abutment surfaces can be provided at each step.
  • the contact sections 5, 6 are designed such that their stages 11, 12 are each mounted along different sized concentric arranged imaginary contact circles 15, 16, wherein each two stages 11, 12 of the contact sections. 5 6 extend along one and the same imaginary system 15, 16.
  • FIG. 3 differs from FIG. 2 in that four contact sections 5, 6, 7 and 8 can be seen in FIG.
  • Each of these four bearing sections 5, 6, 7, 8 each comprises two stages 11, 12, wherein at these stages 11, 12 each contact surfaces 13, 14 are executed.
  • the axle bridge 1 shown in FIG. 3 is designed so that the step 11 of each contact section 5, 6, 7, 8 is arranged along an imaginary contact circle 15.

  • the two contact circuits 15, 16 are arranged coaxially with each other.
  • 4 shows a first possible mounting position of the differential bearing assembly 4 on the axle 1, wherein a second possible mounting position of the differential bearing assembly 4 at the axle bridge 1 in Fig. 5 is shown. It can be clearly seen that the second mounting position is rotated relative to the first mounting position about a rotational axis A of the differential bearing assembly 4.
  • This rotation of the differential bearing arrangement about the axis of rotation A can be, for example, up to 180 °. The direction of rotation is irrelevant.
  • differential bearing assembly 4 comprises two fastening elements 9, 10 which define a differential cage 18 indirectly radially and axially.
