Abstract

A side under-ride collision guard is described configured to be mounted on a large trailer equipped with a sliding rear axle, comprising at least two linear fixed energy absorbing beam structures mounted axially with the trailer and attached to a plurality of support members connecting the beam structures to opposing ends of the trailer's floor beams, and at least two linear telescoping beam structures axially adjustable for position with respect to the fixed beam structures. The guard diminishes the impact hazard to other roadway users that is presented by the lower axial edge(s) of the cargo compartment in the two outboard regions that exist between the trailer's protected regions, which are typically the landing legs or prime mover rear tires to the front and the trailer's sliding axle assembly to the rear of the trailer.

Claims (28)

1. A side under-ride collision guard configured to be mounted on a large trailer equipped with a sliding rear axle and having a plurality of floor beams, comprising:

a plurality of linear fixed energy absorbing beam structures mounted axially with said trailer, said beam structures attached to a plurality of support members connecting said beam structures to opposing ends of said trailer's floor beams, and

a plurality of linear telescoping beam structures axially adjustable for position with respect to said fixed beam structures.

2. A side under-ride guard in accordance with claim 1 , in which said support members are connected to opposing ends of a plurality of said trailer's floor beams.

3. A side under-ride guard in accordance with claim 2 , in which said support members are connected to opposing ends of three or more of said trailer's floor beams.

4. A side under-ride guard in accordance with claim 1 , in which said adjustable beam structures are connected to an axle assembly of said trailer by a transverse mount.

5. A side under-ride guard in accordance with claim 1 , wherein said support members include shear plates.

6. A side under-ride guard in accordance with claim 1 , wherein said beam structures are fabricated from wrought aluminum alloy.

7. A side under-ride guard in accordance with claim 1 , wherein said support members redirect support member impact forces to said trailer's floor.

8. A side under-ride guard system for a sliding axle trailer, comprising:

a plurality of fixed energy absorbing guards beneath said trailer's floor forward of said trailer's sliding axle assembly and rearward of said trailer's landing legs,

a plurality of movable energy absorbing guards between said sliding axle assembly and said plurality of fixed energy absorbing guards, and

wherein said fixed beam structures are attached to a plurality of support members connecting said fixed beam structures to opposing ends of said trailer's floor beams.

9. A side under-ride guard in accordance with claim 8 , in which said moveable side guards nest inside of the fixed side guards.

10. A side under-ride guard system in accordance with claim 8 , in which said fixed side guards attach to said trailer's landing legs.

11. A side under-ride guard system in accordance with claim 8 , in which said support members do not connect to said trailer's floor.

12. A side under-ride guard system in accordance with claim 8 , in which said support members are connected to said trailer's floor.

13. A side under-ride guard system in accordance with claim 1 , wherein said fixed linear guard members are fabricated from an aluminum alloy.

14. A side under-ride guard in accordance with claim 8 , in which said support members are connected to opposing ends of a plurality of said trailer's floor beams.

15. A side under-ride guard in accordance with claim 2 , in which said support members are connected to opposing ends of three or more of said trailer's floor beams.

16. A side under-ride guard in accordance with claim 8 , in which said adjustable beam structures are connected to an axle assembly of said trailer by a transverse mount.

17. A side under-ride guard in accordance with claim 8 , wherein said support members include shear plates.

18. A side under-ride collision guard configured to be mounted on a large trailer equipped with a sliding rear axle and having a plurality of floor beams, comprising:

a plurality of linear fixed energy absorbing beam structures mounted axially with said trailer, said beam structures attached to a plurality of support members connecting said beam structures to opposing ends of said trailer's floor beams, and

a plurality of linear telescoping beam structures axially adjustable for position with respect to said fixed beam structures;

and wherein said support members are connected to opposing ends of three or more of said trailer's floor beam;

said adjustable beam structures are connected to an axle assembly of said trailer by a transverse mount; and

said support members include shear plates.
