Definitions

  • the invention relates to a drive device for a motor vehicle, with an axial flow machine, which has a stator and a first rotor section arranged on a first axial side of the stator and spaced apart by a first air gap, and a housing component in which the axial flow machine is mounted and which is thus located in Extends axial direction that the housing component covers the first air gap radially outside of the axial flow machine.
  • EP 2 606 561 B1 discloses an electric machine having a rotor with permanent magnets and a stator with windings wound on stator bars for interaction with the magnets across an air gap defined between them, the rotor for pivoted for rotation with respect to the stator about an axis of rotation, the bars and windings thereon being enclosed by an annular stator casing.
  • the rotor is rotatably mounted directly above the stator.
  • the prior art has the disadvantage that the air gap is covered by the housing component, for example by a laterally raised flange surface, so that the air gap is not accessible and therefore cannot be checked and/or measured.
  • a drive device is to be provided in which the rotor of the axial flow machine can be mounted well in relation to the stator, the transmission unit and the motor unit each form a separately testable unit and the air gap between the rotor and stator is checked and/or after the assembly of the axial flow machine in the housing component can be measured.
  • this object is achieved according to the invention in a generic device in that the housing component has a housing recess radially aligned with the first air gap.
  • a recess is designed in radial alignment with the first air gap in the housing component, for example in a motor cover, through which an air gap check is possible, even if the housing component as such covers the air gap.
  • This has the advantage that the air gap test and thus the verification of a correct installation of the axial flow machine in the housing component is made possible without major structural changes to the housing component.
  • the usually tolerated air gap can be measured and a high performance of the axial flow machine can be guaranteed.
  • the housing recess can be designed as a through hole, preferably extending in the radial direction.
  • the housing recess can be produced in a particularly simple manner and it is possible to pass a tool through or to measure through the housing component.
  • the housing recess can be designed as a threaded hole, an unthreaded hole or a housing clearance. These configurations have proven to be particularly advantageous in terms of their manufacturability and in terms of their closability.
  • the housing recess can be dimensioned in such a way that a testing or measuring tool can be guided through the housing recess to check and/or measure the first air gap.
  • the housing recess has, for example, a sufficiently large diameter to be able to insert a standardized testing or measuring tool through so far that the first air gap can be measured.
  • the housing recess can be closed/closed to the outside, in particular sealed, via a closure component which is formed separately from the housing component. This means that after the air gap has been checked, the housing recess can be closed in a fluid-tight and/or airtight manner by means of the closure component in order to prevent dirt or media from penetrating into an engine interior/an interior space of the housing component.
  • the closure component can be designed as a screw with a sealing ring, a closure plug or a cover.
  • the closure component can be screwed or glued to the housing component, for example.
  • the stator can have a stator recess which is aligned radially with the first air gap and the housing recess. This has the advantage that the air gap check is made possible independently of the specific configuration of the stator, in particular of the accessibility of the air gap determined by the stator.
  • the stator recess can be dimensioned in such a way that the testing or measuring tool can be inserted through the stator recess to check and/or measure the first air gap. This makes it possible to introduce the testing or measuring tool so far into the axial flow machine that the first air gap can be measured.
  • the axial flow machine can have a second rotor section arranged on a second axial side of the stator and spaced apart by a second air gap.
  • the stator is arranged axially between the two rotor sections.
  • the axial flow machine can preferably have a rotor shaft on which the two rotor sections (i.e. the first rotor section and the second rotor section) are mounted in a rotationally fixed manner.
  • the drive device can have a central bearing which supports the rotor shaft, the first rotor section and the second rotor section directly on the housing component.
  • the rotor is not mounted directly on the stator for rotatable mounting relative to the stator, but is mounted directly on the housing component.
  • the housing component usually has a higher strength and/or rigidity than the stator, so that no vibrations arise that could have a disadvantageous effect on the operation of the axial flow machine.
  • the housing component can extend in the axial direction in such a way that the housing component covers the second air gap radially outside of the axial flow machine. This means that, depending on the installation space requirements, the second air gap can also be covered by the housing component, for example by a middle housing.
  • the housing component can have a second housing recess radially aligned with the second air gap.
  • a (further) recess is designed in radial alignment with the second air gap in the housing component, for example in a middle housing, through which an air gap check is possible, even if the housing component as such covers the air gap.
  • the second housing recess can be designed as a through-hole preferably extending in the radial direction.
  • the second housing recess can be designed as a threaded hole, an unthreaded hole or a housing clearance.
  • the second housing recess can be closed/closed to the outside, in particular sealed, via a second closure component which is formed separately from the housing component.

  • the drive device is preferably used in electric axle drives.
  • the invention relates to an air gap measurement in axial flow machines.
  • One (or more) recesses) in the form of a threaded hole or a hole without a thread are designed in radial alignment with the air gap between a rotor and a stator of the axial flow machine in the motor cover/housing component, which is closed again after the air gap test.
  • an opening can also be made in the motor cover/housing component and this can then be closed with a separate cover.
  • the stator can also be positioned in radial alignment with the air gap and at the same radial alignment contain a sufficiently large recess for a test or measuring tool.
  • the air gap covered by the housing component can be checked and measured through this recess using a suitable testing or measuring tool. After the air gap has been checked, a screw with a seal or a sealing plug or a cover or the like is fitted into the recess in the housing component in order to close it again. A seal prevents additional media from entering the engine compartment. This ensures that the axial flow machine/motor has a tested and documented air gap after assembly and before delivery so that performance can be guaranteed.
