Angled cross member for a vehicle
A structural assembly for a vehicle, including a first rail extending in the nominal direction of forward vehicle travel, a second rail extending in the nominal direction of forward vehicle travel and a cross member having a main body having a first end and a second end, and being joined inboard of the first end to the first rail and inboard of the second end to the second rail, wherein the first end and second end of the cross member are angled relative to the direction of forward vehicle travel at an obtuse angle.
1. A structural assembly for a vehicle, comprising:
a first rail extending in a nominal direction of forward vehicle travel;
a second rail extending in the nominal direction of forward vehicle travel;
a cross member having a main body having a first end and a second end, and being joined inboard of the first end to the first rail and inboard of the second end to the second rail, wherein the first end and second end of the cross member are angled relative to the direction of forward vehicle travel at an obtuse angle of between 135 and 165 degrees.
2. The assembly of claim 1 wherein the main body has a forward facing surface that is concave and a rearward facing surface that is convex.
3. The assembly of claim 2 wherein the forward facing surface of the cross member has a length between the first end and second end, and wherein the forward facing surface is curved and has a ratio of a radius of curvature to length of between 0.7 and 4.5.
4. The assembly of claim 1 wherein the cross member is coupled to a main side rail of the vehicle chassis.
5. The assembly of claim 1 wherein the first end and second end are mirror images of each other.
6. The assembly of claim 1 which also includes an engine cradle and wherein the first rail and second rail are coupled to and/or define part of the engine cradle.
7. The assembly of claim 1 wherein the first rail and second rail are adapted to be received closer to a fore-aft centerline of the vehicle than are wells for vehicle front wheels.
8. The assembly of claim 7 wherein a cross-car length of the cross member is less than a cross-car distance between the wells for the vehicle front wheels.
9. The assembly of claim 1 which also comprises a connector coupled to the first rail and including a threaded section, a bushing aligned with the threaded section, and a bolt received through the bushing and having threads received in the threaded section, and wherein the cross member includes an opening into which the bushing extends and wherein the bushing engages the connector and the cross member is coupled to the first rail by the bolt, bushing and connector.
10. The assembly of claim 9 wherein the bushing mechanically interlocks with the connector providing a joint area larger than the diameter of the bolt.
11. The assembly of claim 10 wherein the connector includes a counterbore defined by a flange and wherein an end of the bushing is received within the counterbore such that the flange surrounds and axially overlaps the end of the bushing.
12. The assembly of claim 10 wherein the bushing is tubular and has an inner surface that defines an inner diameter that is larger than the outer diameter of the bolt providing clearance between the inner surface and the bolt.
13. A structural assembly for a vehicle, comprising:
a first rail extending in a nominal direction of forward vehicle travel;
a second rail extending in the nominal direction of forward vehicle travel;
a cross member having a main body having a first end and a second end, and being joined inboard of the first end to the first rail and inboard of the second end to the second rail, wherein the first end and second end of the cross member are angled relative to the direction of forward vehicle travel at an obtuse angle, wherein the first end and second end include a forward surface and a rearward surface, where the forward surface leads the rearward surface of the vehicle in forward vehicle travel, and wherein the forward surface is closer to a fore-aft centerline of the vehicle than is the rearward surface.
14. A structural assembly for a vehicle, comprising:
a chassis having a first portion and a second portion spaced from the first portion in a cross-car direction; and
a cross member having a main body having a first end and a second end, and being joined inboard of the first end to the first portion of the chassis and inboard of the second end to the second portion of the chassis, wherein the first end and second end of the cross member are angled relative to a direction of forward vehicle travel at an obtuse angle, wherein the first end and second end include a forward surface and a rearward surface, where the forward surface leads the rearward surface of the vehicle in forward vehicle travel, and wherein the forward surface is closer to a fore-aft centerline of the vehicle than is the rearward surface.
15. The assembly of claim 14 wherein the main body has a forward facing surface that is concave and a rearward facing surface that is convex.
16. The assembly of claim 15 wherein the forward facing surface has a length between the first end and second end, and wherein the forward facing surface is curved and has a ratio of a radius of curvature to length of between 0.7 and 4.5.
17. The assembly of claim 14 wherein the angle is between 135 and 165 degrees.
