[0056] FIG. 7 shows a chassis module for mounting an axle construction according to an embodiment of the present disclosure, and

[0057] FIG. 8 shows a motor vehicle chassis having an axle construction according to an embodiment of the present disclosure.

[0058] The preferred embodiments of the present disclosure described in the Figures partially correspond, wherein the same reference numerals are used for similar or identical components and, for the explanation thereof, reference may also be made to the description of the other embodiments. For the sake of clarity, not all the components in all the Figures have been given reference numerals.

[0059] FIG. 1 is a highly schematic, perspective view of an axle construction 10 for a motor vehicle according to a first embodiment of the present disclosure, wherein FIG. 2 is a highly schematic side view of the first embodiment. FIG. 3 is a detailed plan view of the axle construction 10, wherein FIG. 4 is a detailed perspective view of the axle construction 10. The axle construction 10 of the exemplary first embodiment of the present disclosure is described with common reference to FIGS. 1 to 4.

[0060] The axle construction 10 is intended in particular for use with a utility vehicle, for example, a truck, and is consequently in particular a utility vehicle axle construction 10. The axle construction 10 is used initially in conventional manner for assembly of a first (for example, advantageously right) wheel W1 which is illustrated only schematically in FIG. 3, and a second (advantageously, for example, left) wheel W2 which is illustrated only schematically in FIG. 3, wherein, for example, single or dual tires are possible.

[0061] The reference numeral L indicates the longitudinal direction of the motor vehicle. The reference numeral Q indicates the transverse direction of the motor vehicle. The reference numeral H indicates the vertical direction of the motor vehicle.

[0062] The axle construction 10 is provided with a first brake cylinder 1 with the brake caliper B1 and a second brake cylinder 2 with the brake caliper B2.

[0063] The first brake cylinder 1 comprises a center line 1.1 and is advantageously used to brake the first wheel W1, wherein the second brake cylinder 2 comprises a second center line 2.1 and is advantageously used to brake the second wheel W2.

[0064] An axle gear G serves to connect a drive shaft for driving the motor vehicle, in particular the first wheel W1 and the second wheel W2.

[0065] A particular feature is that the first brake cylinder 1 is optionally arranged together with the brake caliper B1 thereof at one side S1 of the reference plane P and consequently in particular in the longitudinal direction L of the motor vehicle, for example, in front of the axle construction 10, and the second brake cylinder 2 is optionally arranged together with the brake caliper B2 thereof at the other side S2 of the reference plane P and consequently in particular in the longitudinal direction L of the motor vehicle, for example, behind the axle construction 10.

[0066] In the first embodiment, the first center line 1.1 and the second center line 2.1 extend substantially parallel with the reference plane P and in particular substantially parallel with the longitudinal axis 10.1 and consequently in particular substantially horizontally. In the context of the present disclosure, however, it is not absolutely necessary for the first center line 1.1 and the second center line 2.1 to extend parallel and/or horizontally, but instead it is, for example, also possible for the first center line 1.1 to extend, for example, parallel with the longitudinal axis 10.1, wherein the second center line 2.1 extends in a non-parallel manner with respect to the longitudinal axis 10.1 and/or in a non-horizontal manner (for example, in an extreme case, substantially vertically), or vice versa.

[0067] FIG. 5 is a highly schematic plan view of an axle construction 10 according to a second embodiment, wherein FIG. 6 is a detailed plan view of the axle construction 10. The axle construction 10 of the exemplary second embodiment is described with common reference to FIGS. 5 and 6.

[0068] Firstly, in the second embodiment, the first center line 1.1 and the second center line 2.1 may also extend substantially horizontally.

[0069] However, a particular feature is that the first center line 1.1 is orientated to be inclined away from the reference plane P and/or the longitudinal axis 10.1 so that a space R1 between the first brake cylinder 1 and the axle construction 10 can be increased. However, the second center line 2.1 may be orientated to be inclined toward the reference plane P and/or the longitudinal axis 10.1 so that a space R2 between the second brake cylinder 2 and the axle construction 10 can be reduced. In this instance, it is possible for the angle of inclination of the first center line 1.1 and the angle of inclination of the second center line 2.1 to be substantially of the same size or of different sizes. In the second embodiment, the first center line 1.1 and the second center line 2.1 consequently extend in a non-parallel manner with respect to the reference plane P and in a non-parallel manner with respect to the longitudinal axis 10.1.

[0070] Furthermore, embodiments are possible in which both the first center line 1.1 and the second center line 2.1 are orientated to be inclined away from the reference plane P and/or the longitudinal axis 10.1, or in which both the first center line 1.1 and the second center line 2.1 are orientated to be inclined toward the reference plane P and/or the longitudinal axis 10.1.

[0071] The first embodiment and the second embodiment preferably comprise an axle gear G for connecting a drive shaft.

[0072] However, embodiments with a single-wheel drive are also possible. Thus, the axle construction 10 may, for example, have a first single-wheel motor for driving the first wheel W1 and a second single-wheel motor for driving the second wheel W2. In this instance, it is possible for the first single-wheel motor to be arranged at least partially or substantially completely at one side S1 of the reference plane P and/or for the second single-wheel motor to be arranged at least partially or substantially completely at the other side S2 of the reference plane P.

[0073] FIG. 7 shows a chassis module C6 for assembly of an axle construction 10 according to an embodiment of the present disclosure, wherein FIG. 8 shows a motor vehicle chassis 100 having a chassis module C6 which has an axle construction as shown in FIG. 7 and a large number of additional chassis modules C1 to C5.

[0074] The individual chassis modules C1 to C6 preferably have four front connection nodes K′ (FIG. 7) and four rear connection nodes K′ (FIG. 7), wherein the connection nodes K′ may be constructed, for example, as a cast, forged or sheet metal component. The individual connection nodes K′ of the chassis modules C1 to C6 serve to form releasable connection node pairs K (FIG. 8), via which the chassis modules C1 to C6 can be releasably connected to each other in order to be able to form the chassis 100. It is possible to use, for example, screw or clamping connections as releasable connection techniques.

[0075] The chassis module C6 is consequently preferably connected to the chassis module C5 by means of preferably four connection node pairs K, wherein the chassis module C5 is connected to the chassis module C4 preferably by means of four connection node pairs K, etc.

[0076] The individual chassis modules C1 to C6 may have as a carrier structure, for example, a plurality of longitudinal carriers, a plurality of transverse carriers and a plurality of vertical carriers which may advantageously be configured, for example, as sheet metal or profile components, but may also comprise, for example, substantially plate-like carrier structures. The profile components may be closed or open profiles, for example, hollow profiles or, for example, substantially U-, L-, I- or hat-like profiles. The carrier structure of the individual chassis modules C1 to C6 is consequently advantageously not configured, as in, for example, a ladder-frame-like chassis in a 2-dimensional manner, but instead preferably in a 3-dimensional manner, for example, as a framework and/or box construction, as shown, for example, in FIGS. 7 and 8 by way of example.

[0077] The present disclosure is not limited to the above-described preferred embodiments. Instead, a large number of variants and modifications which also make use of the notion of the present disclosure and which are therefore included within the scope of protection are possible. Furthermore, the present disclosure also claims protection for the subject-matter and the features of the dependent claims regardless of the features and claims which are referred to.
