Description

[0037] The invention will be explained in detail below on the basis of the exemplary embodiments illustrated in the drawing, without resulting in any limitation of the invention. Shown are:

[0038] FIG. 1 a schematic cross-sectional illustration through a region of a motor vehicle;

[0039] FIG. 2 a side view of the region of the motor vehicle; and

[0040] FIG. 3 a detailed view of a plurality of individual wheel drives.

[0041] FIG. 1 shows a cross-sectional illustration through a region of a motor vehicle 1. Illustrated are wheels 2 and 3 of an electrically driven axle 4. Associated with each wheel 2 and 3 is an individual wheel drive 5. Each individual wheel drive 5 has an electric motor 6 with a motor housing 7. Attached at the motor housing 7 is an electronic component 8, in particular an electronics housing 9 of the electronic component 8. Each electronic component 8 has an electrical plug connection device 10, which serves for producing a detachable electrical connection to a plug connection element 11.

[0042] At least the electronic components 8, but preferably the individual wheel drives 5, are designed as identical parts. This means that identical electronic components 8 or individual wheel drives 5 can be associated with the wheels 2 and 3. This is indicated by the arrow 12. The individual wheel drive 5, associated with the wheel 2, in this regard, can be converted by a simple rotation by 180° to the individual wheel drive 5, associated with the wheel 3.

[0043] This is achieved, in particular, in that the plug connection device 10 is arranged at a lug 13 projecting from the electronics housing 9. Preferably, in this case, the plug connection devices 10 are designed bidirectionally, so that the plug connection elements 11 can always be brought to the plug connection device 10—viewed geodetically—from below. This is achieved, for example, in that the lug 13 has two opposite-lying connection surfaces 14 and 15. Provided at the connection surface 14 is then a first plug connector, whereas, at the connection surface 15, a second plug connector is present. These are electrically wired identically, so that the same electrical connection can be produced between the plug connection element 11 and the electronic component 8 both by mounting the plug connection element 11 at the first plug connector and by mounting at the second plug connector.

[0044] However, it can also be provided that the respective plug connector is always arranged only at the connection surface 14 or 15 of the lugs 13 that has a corresponding orientation, for example geodetically below the other connection surface 15 or 14 in each instance.

[0045] Preferably, it is provided that the connection surfaces 14 and 15 are parallel to each other. In the exemplary embodiment illustrated here, the lug 13 has, in the direction of the normal line of the connection surfaces 14 and 15, dimensions that are at most 25% of the dimensions of the electronics housing 9 in the same direction. At the same time, the lug is centered between two lateral surfaces 16 and 17 of the electronics housing 9, which delimit the electronics housing 9 in the direction of the normal line mentioned above.

[0046] Especially preferred, the lug 13, viewed in cross section, lies at the level of an axis of rotation 18 of the electric motor 6; for example, the lug 13 is centered in relation to the axis of rotation 18—viewed in cross section. The axis of rotation 18 therefore passes through the lug 13 or intersects it at the center. In such an embodiment, the plug connection element 11 can always be mounted in a straightforward manner from the same direction, regardless of the orientation in which the electronic component 8 is mounted at the motor housing 7. In addition, the plug connection element 11 and/or a lead extending from it is always arranged, at least in regions, next to the electronics housing 9 and/or next to the motor housing 7, so that a certain protection against detrimental mechanical effects is afforded.

[0047] It is clear that the individual wheel drives 5 can be arranged in a straightforward manner between installation space boundaries 19, 20, and 21. The installation space boundary 19 is defined by a body of the motor vehicle 1, in particular by a body panel. The installation space boundary 20, in contrast, is defined by a subsurface or ground on which the motor vehicle 1 moves. The installation space boundaries 21 are predetermined by the wheels 2 and 3.

[0048] FIG. 2 shows a side view of the individual wheel drive 5. Illustrated in addition to the installation space boundaries 19 and 20 are now installation space boundaries 22 and 23, which, for example, are determined depending on the axle 4. For example, the installation space boundaries 22 and 23 are likewise defined by the body of the motor vehicle 1. Even though the leads 24 extending from the plug connection element 11 have to be designed with a minimum radius of curvature, the arrangement of the leads 24, governed by the special arrangement of the lug 13 at the electronics housing 9, is possible in a straightforward manner.

[0049] FIG. 3 shows another illustration of two individual wheel drives 5, which, in accordance with the above designs, each have the electric motor 6 and the electronic component 8. Clearly seen here once again is the centered arrangement of the lug 13 and the mounting situation of the plug connection elements 11 resulting from it.
