Methods and apparatus for a strut assembly for an aerodynamic trucking system
A strut assembly for mounting an aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a centerline, transverse structural support members extending between sides of the trailer, and longitudinal members extending along a length of the trailer. The strut assembly may comprise a mounting plate, a strut body, and a substantially rectangular composite spring. The mounting bracket comprising a mounting plate and a pair of spaced apart sidewalls. The strut body rotatably may be coupled to the pair of spaced apart sidewalls on the mounting bracket. The substantially rectangular composite spring may be coupled to an upper surface of the strut body and configured to contact an underside of the mounting plate of the mounting bracket to resist inward deflection from an external force applied to the strut body.
1. A strut assembly for mounting an aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a centerline, transverse structural support members extending between sides of the trailer, and longitudinal members extending along a length of the trailer, the strut fairing assembly comprising:
a mounting bracket comprising a mounting plate and a pair of spaced apart sidewalls;
a strut body rotatably coupled to the pair of spaced apart sidewalls on the mounting bracket; and
a substantially rectangular composite spring coupled to an upper surface of the strut body and configured to engage an underside of the mounting plate of the mounting bracket to resist inward deflection from an external force.
2. The strut assembly of claim 1 , wherein the mounting bracket is coupled to one or more or of the transverse structural support members by a clamping mechanism.
3. The strut assembly of claim 2 , wherein the clamping mechanism comprises a pair of spaced apart clamping plates each having a mounting portion and a raised portion, wherein the mounting portion is coupled to the mounting plate of the mounting bracket and the transverse structural support members are received within a channel between the raised portion of the clamping plates and an upper surface of the mounting plate to couple the strut assembly to the trailer.
4. The strut assembly of claim 1 , wherein the pair of spaced apart sidewalls of the mounting bracket contain a pair of forward apertures and a pair of rear apertures; wherein:
the pair of forward apertures are configured to rotatably couple the strut body to the mounting bracket with a fastener; and
the pair of rear apertures are configured to couple a roller to the mounting bracket with a fastener, wherein an upper surface of the substantially rectangular composite spring contacts a lower surface of the roller.
5. The strut assembly of claim 4 , wherein each of the pair of spaced apart sidewalls contain an angled notch at a forward end of the mounting bracket.
6. The strut assembly of claim 5 , wherein the substantially rectangular composite spring is coupled to an upper mounting surface of the strut body by a spring washer.
7. The strut assembly of claim 6 , wherein the spring washer comprises a protrusion that projects outwardly of the pair of spaced apart sidewalls and resides within the angled notch of the mounting bracket.
8. The strut assembly of claim 7 , wherein upon inward deflection of the strut toward the centerline of the trailer, the strut body moves inwardly and rotates at the connection between the strut body and the mounting bracket to cause the upper mounting surface of the strut body to deflect the rectangular composite spring.
9. The strut assembly of claim 1 , wherein the strut body extends downwardly from the mounting bracket.
10. The strut assembly of claim 9 , wherein the strut body comprises a panel support having a downwardly-projecting support member.
11. The strut assembly of claim 10 , wherein the downwardly-projecting support member comprises a pair of spaced apart side walls coupled to the panel support.
12. The strut assembly of claim 1 , wherein the substantially rectangular composite spring is coupled to an upper surface of the strut body by a spring washer.
13. The strut assembly of claim 12 , wherein the pair of spaced apart sidewalls of the mounting bracket each comprise an angled notch.
14. The strut assembly of claim 13 , wherein a protrusion on the spring washer is received within the angled notch on the mounting bracket and configured to limit the rotation of the strut body inwardly towards the centerline of the trailer upon impact from a foreign member.
15. A strut assembly for mounting an aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a centerline, transverse structural support members extending between sides of the trailer, and longitudinal members extending along a length of the trailer, the strut fairing assembly comprising:
a mounting bracket comprising a mounting plate and a pair of spaced apart sidewalls each comprising an angled notch;
a strut body rotatably coupled to the pair of spaced apart sidewalls on the mounting bracket; and
a substantially rectangular composite spring coupled to an upper surface of the strut body by a spring washer, wherein a protrusion on the spring washer is received within the angled notch on the mounting bracket and configured to limit the rotation of the strut body inwardly towards the centerline of the trailer upon impact from a foreign member.
16. The strut assembly of claim 15 , wherein the mounting bracket is coupled to one or more or of the transverse structural support members by a clamping mechanism.
17. The strut assembly of claim 16 , wherein the clamping mechanism comprises a pair of spaced apart clamping plates each having a mounting portion and a raised portion, wherein the mounting portion is coupled to the mounting plate of the mounting bracket and the transverse structural support members are received within a channel between the raised portion of the clamping plates and an upper surface of the mounting plate to couple the strut assembly to the trailer.
18. The strut assembly of claim 15 , wherein the pair of spaced apart sidewalls of the mounting bracket contain a pair of forward apertures and a pair of rear apertures; wherein:
the pair of forward apertures are configured to rotatably couple the strut body to the mounting bracket with a fastener; and
the pair of rear apertures are configured to couple a roller to the mounting bracket with a fastener, wherein an upper surface of the substantially rectangular composite spring contacts a lower surface of the roller.
19. The strut assembly of claim 15 , wherein the strut body extends downwardly from the mounting bracket.
20. The strut assembly of claim 19 , wherein the strut body comprises a panel support having a downwardly-projecting support member, wherein the downwardly-projecting support member comprises a pair of spaced apart side walls coupled to the panel support.
