Abstract

A frame unit for utility vehicles includes outer and inner parts and a transverse region, wherein the transverse region extends substantially transversely to the outer part and/or the inner part, wherein the transverse region is integrally formed with the outer part or the inner part, the outer part and/or the inner part has a fastening region for being secured to a vehicle frame, the outer part has an outer bearing region and the inner part has an inner bearing region, an axle guide can be arranged between the outer and inner bearing regions and can be secured to the bearing regions such that the axle guide can pivot about a bearing axis, and wherein the transverse region secures the outer part and/or the inner part against pivoting about an orthogonal in relation to the bearing axis.

First claim

The invention claimed is:

1. A frame unit for utility vehicles, comprising:
an outer part;
an inner part; and
a transverse region;
wherein the transverse region and the outer part extend substantially transversely in relation to one another and/or the transverse region and the inner part extend substantially transversely in relation to one another;
wherein the transverse region is integrally formed with the outer part or with the inner part;
wherein the outer part and/or the inner part has a fastening region configured to be secured to a vehicle frame;
wherein the outer part has an outer bearing region and the inner part has an inner bearing region;
wherein an axle guide is arranged between the outer and the inner bearing region and is secured to the bearing regions such that the axle guide pivots about a bearing axis;
wherein the transverse region is configured to absorb torques of the outer part and/or inner part about an orthogonal in relation to the bearing axis;
wherein the transverse region extends substantially along a parallel in relation to the bearing axis;
wherein the first frame unit has a first outer part, a first inner part and a first transverse region, wherein the second frame unit has a second outer part, a second inner part and a second transverse region, wherein the first inner part and the second inner part are arranged between the first outer part and the second outer part, and wherein the first transverse region and the second transverse region are configured to be or are indirectly or directly secured to one another or are integrally formed with one another; and
wherein the first transverse region and the second transverse region form an overlap region, wherein a connection between the first and the second transverse region can be established in the overlap region, which connection transmits bending moments about an orthogonal in relation to the longitudinal axis.

2. The frame system as claimed in claim 1 , wherein the overlap region has an extent parallel in relation to the bearing axis that is 0.02 to 0.09 times a maximum distance of the two outer parts from one another.

3. The frame system as claimed in claim 2 , wherein the extent of the overlap region in relation to the bearing axis is 0.1 to 0.2 times the maximum distance of the outer two parts from one another.

4. The frame system as claimed in claim 2 , wherein the extent of the overlap region in relation to the bearing axis is 0.21 to 0.3 times the maximum distance of the outer two parts from one another.

5. A frame unit for utility vehicles, comprising:
an outer part;
an inner part; and
a transverse region;
wherein the transverse region and the outer part extend substantially transversely in relation to one another and/or the transverse region and the inner part extend substantially transversely in relation to one another;
wherein the transverse region is integrally formed with the outer part or with the inner part;
wherein the outer part and/or the inner part has a fastening region configured to be secured to a vehicle frame;
wherein the outer part has an outer bearing region and the inner part has an inner bearing region;
wherein an axle guide is arranged between the outer and the inner bearing region and is secured to the bearing regions such that the axle guide pivots about a bearing axis;
wherein the transverse region is configured to absorb torques of the outer part and/or inner part about an orthogonal in relation to the bearing axis;
wherein the transverse region extends substantially along a parallel in relation to the bearing axis;
wherein the first frame unit has a first outer part, a first inner part and a first transverse region, wherein the second frame unit has a second outer part, a second inner part and a second transverse region, wherein the first inner part and the second inner part are arranged between the first outer part and the second outer part, and wherein the first transverse region and the second transverse region are configured to be or are indirectly or directly secured to one another or are integrally formed with one another; and
wherein the first transverse region and the second transverse region are indirectly and/or directly fastened to one another in an interlocking manner, and wherein a connecting element is configured to be brought into engagement with the first transverse region and with the second transverse region to transmit a bending moment about an orthogonal in relation to the bearing axis from the first to the second transverse region and vice versa.
