An apparatus turns a front wheel of a vehicle inward during an offset frontal impact. The apparatus includes a first frame rail and a second frame rail spaced from each other. A bumper is supported by the first and second frame rails. A beam extends between and engages the first and second frame rails. The beam includes an extension extending from the first frame rail away from the second frame rail to a first end spaced from the first frame rail for being positioned forward of the front wheel and for being forced into the front wheel during the offset frontal impact.
1. An apparatus for turning a front wheel of a vehicle inward during an offset frontal impact, the apparatus comprising:
a first frame rail and a second frame rail spaced from each other, the first frame rail and the second frame rail each including a tubular wall and each including first and second passages extending through the tubular wall;
a bumper supported at ends of the first and second frame rails spaced from the first and second passages of the first and second frame rails, the first and second frame rails each extending from the respective first and second passages toward the bumper; and
a beam extending through the passages of the first and second frame rails and engaging the first and second frame rails;
the beam including an extension extending from the first frame rail away from the second frame rail to a first end spaced from the first frame rail for being positioned forward of the front wheel and for being forced into the front wheel during the offset frontal impact.
2. The apparatus as set forth in claim 1 wherein the beam is unitary.
3. The apparatus as set forth in claim 1 wherein the extension is cantilevered from the first frame rail.
4. The apparatus as set forth in claim 1 wherein the beam is welded to the first frame rail at the first passage and the second passage of the first frame rail.
5. The apparatus as set forth in claim 1 wherein the first and second frame rails extend in parallel and the beam is orthogonal to the first and second frame rails.
6. The apparatus as set forth in claim 1 wherein the beam includes a second extension extending from the second frame rail away from the first frame rail to a second end spaced from the second frame rail.
7. The apparatus as set forth in claim 1 wherein the beam is welded to the first frame rail and the second frame rail.
8. The apparatus as set forth in claim 6 wherein the beam extends along a straight axis from the first end to the second end.
9. The apparatus as set forth in claim 1 wherein the first frame rail is configured to bend in response to relative movement of the beam during the offset frontal impact.
10. The apparatus as set forth in claim 9 wherein the second frame rail is configured to bend in response to relative movement of the beam during the offset frontal impact.
11. The apparatus as set forth in claim 1 wherein the beam is welded to the first frame rail and the second frame rail.
12. The apparatus as set forth in claim 1 further comprising a cab mounting support mounted to the beam.
13. The apparatus as set forth in claim 12 wherein the cab mounting support is mounted to the extension of the beam.
14. The apparatus as set forth in claim 1 further comprising a tire deflation device on the extension.
15. The apparatus as set forth in claim 1 wherein the first frame rail and the second frame rail define an engine cradle.
16. The apparatus as set forth in claim 1 further comprising shock tower brackets fixed to the first frame rail and the second frame rail.
17. The apparatus as set forth in claim 1 wherein the first frame rail and the second frame rail support a passenger compartment of the vehicle.
