Abstract

A vehicle suspension structure includes a frame member having a first side portion and a bottom portion. The bottom portion extends in a first direction relative to the first side portion. The structure also includes a suspension mounting member attached to the first side portion of the frame member. The suspension mounting member extends in a second direction that is opposite of the first direction. The structure also includes a support bracket attached to the bottom portion of the frame member and the suspension mounting member. The structure further includes a suspension member rotatably coupled to the suspension mounting member and supporting a vehicle wheel.

Claims (33)

1. A vehicle suspension structure, comprising:

a frame member having a first side portion and a bottom portion, the bottom portion extending in a first direction relative to the first side portion;

a suspension mounting member attached to the first side portion of the frame member, the suspension mounting member extending in a second direction that is opposite of the first direction;

a support bracket attached to the bottom portion of the frame member and the suspension mounting member; and

a suspension member rotatably coupled to the suspension mounting member and supporting a vehicle wheel,

wherein the suspension mounting member provides a structural support for rotatably interconnecting the frame member with the suspension member, the support bracket includes a first support bracket portion and a second support bracket portion, the first support bracket portion has a first mating surface portion generally defining a first plane, the second support bracket portion has a second mating surface portion generally defining a second plane, the first support bracket portion has a first support bracket bead formed therein, the first support bracket bead extends toward the second support bracket portion, the second support bracket portion includes a suspension mounting member connecting portion and a second support bracket bead formed therein.

2. The structure of claim 1 , wherein the support bracket is selectively bolted to the frame member and the first plane is generally perpendicular to the second plane.

3. The structure of claim 1 , wherein the first support bracket bead intersects the second support bracket bead.

4. The structure of claim 1 , wherein the thickness of the support bracket, measured normal to a support bracket surface portion, is generally constant throughout.

5. The structure of claim 1 , wherein the support bracket is spot welded to the trailing arm bracket.

6. The structure of claim 1 , wherein the trailing arm bracket includes a pair of ears, a portion of the trailing arm is selectively positioned between the ears, and wherein the ears and the first side portion are generally vertically oriented.

7. An apparatus for connecting a wheel to a vehicle body comprising:

a frame member connected to a vehicle body and including a tubular portion defined, at least in part, by a first side, a second side, and a bottom portion;

a trailing arm bracket in contact with the frame member; and

a stamped metal reinforcing bracket in contact with both the frame member and the trailing arm bracket,

wherein the trailing arm bracket, at least in part, provides a structural support for rotatably interconnecting the frame member with a trailing arm;

wherein the reinforcing bracket includes a first reinforcing bracket portion and a second reinforcing bracket portion, the first reinforcing bracket portion has a first mating surface portion generally defining a first plane, the second reinforcing bracket portion has a second mating surface portion generally defining a second plane, the first reinforcing bracket portion has a first reinforcing bracket bead formed therein, the first reinforcing bracket bead extends toward the second reinforcing bracket portion, the second reinforcing bracket portion includes a trailing arm connecting portion and a second reinforcing bracket bead formed therein.

8. The apparatus of claim 7 , wherein the frame member is an elongated rectangular frame member that extends generally longitudinally along the vehicle body, the first side is generally defined by a first plane, and the first plane is positioned between the trailing arm and the bottom portion.

9. The apparatus of claim 7 ,wherein the reinforcing bracket is selectively spot welded to the trailing arm bracket, and selectively bolted to the frame member.

10. The apparatus of claim 7 , wherein the reinforcing bracket further includes a frame support portion extending generally perpendicularly from the first reinforcing bracket portion, wherein the first reinforcing bracket portion interconnects the second reinforcing bracket portion and the frame support portion.

11. The apparatus of claim 7 , wherein the bead provides stiffness for the reinforcing bracket and permits fluids to pass between the reinforcing bracket and the trailing arm bracket.

12. The apparatus of claim 7 , further comprising a trailing arm rotatably coupled to the trailing arm bracket, wherein the trailing arm bracket, at least in part, provides a structural support for rotatably interconnecting the frame member with a trailing arm, the trailing arm bracket includes a pair of bracket ears, the trailing arm includes a socket, the socket is selectively interposed between the bracket ears, and wherein the socket is not positioned below the tubular portion of the frame member.

13. The apparatus of claim 12 , wherein the trailing arm is connected to the body via a spring and a shock absorber.

14. An apparatus for connecting a wheel to a vehicle body comprising:

a trailing arm bracket in contact with a frame member &the body;

a stamped metal reinforcing bracket in contact with both the frame member and the trailing arm bracket; and

a trailing arm having a socket axis rotatably coupled to the trailing arm bracket, wherein the trailing arm bracket provides a structural support for rotatably interconnecting the frame member with a trailing arm,

wherein the reinforcing bracket includes a first reinforcing bracket portion and a second reinforcing bracket portion, the first reinforcing bracket portion has a first mating surface portion generally defining a first plane, the second reinforcing bracket portion has a second mating surface portion generally defining a second plane, the first reinforcing bracket portion has a first reinforcing bracket bead formed therein, the first reinforcing bracket bead extends toward the second reinforcing bracket portion, the second reinforcing bracket portion includes a trailing arm connecting portion and a second reinforcing bracket bead formed therein.

15. The apparatus of claim 14 , wherein the trailing arm bracket includes a pair of bracket ears, the trailing arm includes a socket, and the socket is selectively interposed between the bracket ears, the trailing arm is connected to the trailing arm bracket for relative rotation generally about the socket axis by an elongated member that extends through the bracket ears and the socket.

16. The apparatus of claim 14 , wherein the reinforcing bracket further includes a frame support portion extending generally perpendicularly from the first reinforcing bracket portion, wherein the first reinforcing bracket portion interconnects the second reinforcing bracket portion and the frame support portion.

17. The apparatus of claim 14 , further comprising

a second trailing arm having a second socket axis rotatably connected to the vehicle body; and

a cross member interconnecting the trailing arm with the second trailing arm, wherein the frame member is an elongated rectangular tubular frame member that extends generally longitudinally along the vehicle body, and the socket axis and the second socket axis are not parallel.
