Description

[0037] The invention is explained in more detail in the following by means of figures, without limiting the invention. The following is shown:

[0038] FIG. 1 a schematic view of an area of a single-wheel drive component for a motor vehicle;

[0039] FIG. 2 a schematic view of the single-wheel drive component, wherein a bracket is provided for an additional assembly; and

[0040] FIG. 3 a schematic view of the single-wheel drive component, wherein the additional assembly is arranged on and attached to the bracket.

[0041] FIG. 1 shows a schematic view of an area of a single-wheel drive component 1 for a motor vehicle. The single-wheel drive component 1 has a drive assembly 2, which has a drive shaft 4 which can rotate about an axis of rotation 3. The drive shaft 4 is preferably rigidly coupled to a cardan shaft 5, which is only shown here in very simplified form, or is designed as a cardan shaft 5. The drive assembly 2 and/or a drive shaft 4 is connected to a wheel hub, which is not shown here, of the single-wheel drive component 1 via the cardan shaft 5.

[0042] The drive assembly 2 has a motor housing 6, on which mounting flange 7 and 8 are formed. For example, mounting flange 7 and 8 are formed with the motor housing 6 as a single piece and with uniform material. Assembly supports 9 and 11 as well as further assembly supports 10 and 12 engage at the motor housing 6 and/or the drive assembly 2 via mounting flange 7 and 8.

[0043] Assembly supports 9, 10, 11, and 12 each have an assembly bearing 13 situated apart from the drive assembly 2. Assembly supports 9, 10, 11, and 12 and thus the drive assembly 2 can be coupled to a body, which is not shown here, of the motor vehicle via the assembly bearings 13, namely can be coupled in a vibration-damping manner. To this end, the assembly bearings 13 are elastic and formed, for example, as a hydraulic assembly bearing. In order to mount the wheel carrier, which is not shown here, on which a wheel hub is mounted by means of a wheel bearing, control arms 14 and 15 as well as a further control arm 16 are provided. Control arms 14, 15, and 16 each engage at the wheel carrier on one side and at least one of assembly supports 9, 10, 11, and 12 on the other side.

[0044] In the exemplary embodiment shown here, control arm 14 is shown as a triangular control arm. Accordingly, it is articulated on several of assembly supports 9, 10, 11, 12, namely on assembly support 9 and assembly support 11. In contrast, control arms 15 and 16 are formed as multilink control arms. Control arm 15 engages at further assembly support 10, and further control arm 16 engages at further assembly support 12.

[0045] In order to connect control arms 14, 15, and 16 to assembly supports 9, 10, 11, and 12, a bearing bracket 17, in which a bearing 18 is retained, which is not shown here in detail, is formed at assembly supports 9, 10, 11, and 12. Control arms 14, 15, and 16 are each mounted in a pivotable manner on corresponding assembly supports 9, 10, 11, and/or 12, and/or the respective assembly supports 9, 10, 11, and 12, via the bearings 18. The bearings 18 may be designed as rubber bearings, rubber-metal bearings, or as ball bearings.

[0046] It can be seen that assembly supports 9 and 10, on one side, as well as assembly supports 11 and 12, on the other side, are each attached to the corresponding mounting flange 7 and/or 8 separately from one another. However, a common attachment may also be implemented; for example, to this end, assembly supports 9 and 10 or assembly supports 11 and 12 may each have a common mounting foot.

[0047] The design of the single-wheel drive component 1 described herein provides for an attachment of the wheel carrier to the body via assembly supports 9, 10, 11, and 12 and thus assembly bearing 13. Accordingly, an optimum vibration-damping design and/or connection is implemented to the extent that greater driving comfort is ensured for the motor vehicle.

[0048] FIG. 2 shows a schematic view of the single-wheel drive component 1 in a different view and a slightly different design. Basically, reference is made to the previous statements and only the differences are addressed in the following. The differences are that assembly supports 9 and 10, on one side, as well as assembly supports 11 and 12, on the other side, are each jointly designed as an assembly support component 19.

[0049] As an addition or alternative to the single-part and material-uniform design of assembly supports 9 and 10 as an assembly support component 19, there is a bracket 20 for an additional assembly 21 (not shown) situated on assembly supports 9 and/or 10, common to both in the exemplary embodiment shown here. The bracket 20 is arranged and formed on the side of assembly supports 9 and 10 facing away from control arms 14, 15, and 16. In the axial direction as relates to the axis of rotation 3, the bracket 20 is situated between mounting points, at which assembly supports 9 and 10 are arranged and attached to the mounting flange 7.

[0050] The bracket 20 is present, for example, as a sheet metal part, which is attached to assembly support 9 at points spaced apart from one another. Additionally or alternatively, the bracket 20 may be attached to assembly support 10 at points spaced apart from one another. The attachment of the bracket 20 to assembly support 9 and/or to assembly support 10 is preferably with a firm bond. A firmly bonded attachment may also be implemented, however, in addition or as an alternative. The bracket 20 may have at least one passage 22, with there being four passages 22 in the exemplary embodiment shown here. These passages serve to reduce the weight and to ventilate the additional assembly 21. Additionally or alternatively, the bracket 20 may have one or more beads 23, which serve to reinforce the bracket 20.

[0051] FIG. 3 shows another view of the previously described single-wheel drive component 1. It can be seen that the additional assembly 21 is now attached to the bracket 20. In the exemplary embodiment shown here, the additional assembly 21 is in the form of a pump, which is provided and designed, for example, for operating an active chassis. The integration of the additional assembly 21 into the single-wheel drive component 1 and/or its attachment to assembly supports 9 and 10 enables an especially compact design and additionally provides good protection for the additional assembly 21 from external influences.
