Abstract

Off-road commercial vehicles, for example trucks, can have a rigid but torsionally soft chassis and a torsionally stiff interchangeable superstructure, such as a container, mounted on the chassis. During off-road driving, the chassis can warp, and the torsionally stiff superstructure either interferes with the warping, which can introduce high stresses into the chassis frame, or the superstructure itself is overstressed. Provided is a chassis (2) for a commercial vehicle (1), comprising a chassis frame (3) extending along a longitudinal direction (L) of the chassis (2), a cross beam (11) firmly connected to the chassis frame (3) for supporting an exchangeable superstructure (8) which can be placed on the chassis (2), and a pendulum cross beam (12, 12’) pivotally mounted on the chassis frame (3) for supporting the superstructure (8). The pendulum cross beam allows the chassis frame to twist without subjecting the superstructure placed on the cross beam and the pendulum cross beam to excessive mechanical stress. It also prevents excessive stresses from being introduced into the chassis frame due to the torsional rigidity of the superstructure.

Claims (14)

1. Chassis for a commercial vehicle comprising a chassis frame extending along a longitudinal direction of the chassis, a cross beam firmly connected to the chassis frame for supporting an inter- changeable superstructure which can be placed on the chassis, a pendulum cross beam pivotably mounted on the chassis frame for support- ing the superstructure, a first swing arm element which is rotatably mounted on the chassis frame about a first axis of rotation and which is rotatably mounted on the pendulum cross beam about a second axis of rotation, and a second swing arm element which is rotatably mounted on the chassis frame about a first axis of rotation and which is rotatably mounted on the pendu- lum cross beam about a second axis of rotation, characterized in that an extension of the first swing arm element and an ex- tension of the second swing arm element intersect one another at an instantane- ous center which is positioned below the pendulum cross beam, as viewed in a height direction of the chassis, and characterized in that the two second axes of rotation of the swing arm ele- ments are positioned between the two first axes of rotation of the swing arm ele- ments and the instantaneous center as viewed in the height direction.
2. Chassis according to claim 1, wherein the two first axes of rotation of the swing arm elements, viewed in a transverse direction of the chassis, are arranged at a greater distance from one another than the two second axes of rotation of the swing arm elements so that the first swing arm element and the second swing arm element are positioned obliquely to each other.

3. Chassis according to claim 2, wherein the first swing arm element and the second swing arm element are positioned obliquely with respect to one another such that the first swing arm element and the second swing arm element run towards one another.
4. Chassis according to one of claims 1 - 3, wherein the two first axes of rotation of the swing arm elements are positioned at the same height as viewed in the height direction, the two second axes of rotation of the swing arm elements being positioned at the same height as viewed in the height direction in a starting position of the pendulum cross beam.
5. Chassis according to one of claims 1 - 4, wherein in each case two first swing arm elements and two second swing arm elements are provided, the pendulum cross beam being arranged, as viewed in the longitu- dinal direction, in each case between the two first swing arm elements and be- tween the two second swing arm elements.
6. Chassis according to one of claims 1 - 5, wherein the first swing arm element is mounted rotatably about its first axis of rotation on a first axle element attached to the chassis frame, the second swing arm ele- ment being mounted rotatably about its first axis of rotation on a second axle ele- ment attached to the chassis frame.
7. Chassis according to claim 6, wherein M MARK ARKE ED-U D-UP P COPY COPY MARKED UP COPY the first axle element and the second axle element, as viewed in the longitudinal direction, are guided past or through the pendulum cross beam.
8. Chassis according to claim 7, wherein the pendulum cross beam comprises a first side section, a second side section and a base section arranged between the first side section and the second side section, wherein the first side section and the second side section extend out over an up- per side of the base section, and wherein the first axle element and the second axle element are passed between the first side section and the second side section past the pendulum cross beam.
9. Chassis according to claim 7, wherein the pendulum cross beam comprises a first opening through which the first axle element is passed and a second opening through which the second axle element is passed.
10. Chassis according to one of claims 1 - 9, wherein the cross beam is arranged at the front on the chassis frame, the pendulum cross beam being arranged at the rear of the chassis frame.
11. Chassis according to one of claims 1 - 10, wherein a spring and/or damping apparatus which is arranged between the chassis frame and the pendulum cross beam.
12. Commercial vehicle comprising a chassis according to one of claims 1 - 11. M MARK ARKE ED-U D-UP P COPY COPY MARKED UP COPY
13. Commercial vehicle according to claim 12, further comprising an interchangeable superstructure, which is placed on the cross beam and on the pendulum cross beam.
14. Chassis according to one of claims 1-11, substantially as hereinbefore de- scribed with reference to the accompanying drawings. 1/ 12 5 6 7
