Vehicle with aerodynamic system
First Claim
1. A vehicle comprisingan elongate bed;
- a skirt adjacent to either side of the elongate bed and depending there from;
stabilizers, a plurality of the stabilizers each including a first plate fixed at one end to the bed adjacent one of the skirts and extending inboard beneath the bed to a second end not fixed to the bed and a second plate extending from the second end of the first plate to meet and be fixed to the same one of the skirts at a position displaced downwardly from the fixed end of the first plate, the second plates bending with the skirts flexing inboard, the second plates being principally in tension and the first plates bending with the skirts flexing outboard.

Abstract
A semi-trailer has an elongate bed with skirts depending there from adjacent to either side of the bed. The skirts are laterally flexible and can also flex vertically to overcome obstacles and objects. Elongate plates are mounted at one end to the underside of the bed adjacent one or the other of the depending skirts. The elongate plates extend inwardly beneath the bed and then diagonally downwardly to the adjacent skirt displaced below the attachment to the bed. Leaf springs are superimposed on the underside of the inward extensions of the elongate plates to preload the plates toward the bed of the semi-trailer. The skirts extend from landing leg assemblies on the semi-trailer to longitudinally adjacent the forward outboard tires of the wheel assemblies.

12. A vehicle comprising
an elongate bed; -
a skirt adjacent to either side of the elongate bed, depending from the elongate bed and having a bottom edge; stabilizers, a plurality of the stabilizers each including a first plate fixed at a first end to the bed adjacent one of the skirts and extending inboard beneath the bed to a second end and a second plate extending from the second end of the first plate to meet and be fixed to the same one of the skirts at a position displaced downwardly from the first end of the first plate, the skirts being laterally flexible from their dependency at the elongate bed to at least the skirt position displaced downwardly from the first end of the first plate fixed to the second end of the first plate, the plurality of stabilizers not otherwise being connected to the bed or the skirts, the second plates bending with the skirts flexing inboard with the second ends of the first plates statically positioned against the underside of the bed, the second plates being principally in tension and the first plates bending downwardly from the bed with the skirts flexing outboard. - View Dependent Claims (13, 14)
