초록 ▼

Vehicle mountable subsystems include a modified nose cone, deflecting air between the trailer and its tractor. Drag at the rear is reduced by vertical vanes at its rear corners, mounted by spring biased supports to allow opening rear doors and restoring the deflecting positions upon closing. Air from the top is deflected downwardly across the rear through a transverse upper scoop. A transverse lower scoop directs air from under the trailer upwardly across its rear surface. Both scoops are fabricated from a resilient material to allow compression against a loading dock structure. An undercarriage enclosure, fabricated into a number of longitudinal segments determined by trailer length, having side skirts and a trailer width upper panel, includes an air deflecting front surface and a channeled rear transverse surface. Flexible skirt extension panels depend toward the roadway.

대표청구항 ▼

An air deflecting subsystem for attachment proximate to an upper rear vertical transverse surface of a vehicle, for deflecting a portion of air passing longitudinally over a top surface of a forwardly moving vehicle comprises: a transversely spaced apart plurality of substantially planar vertical support members respectively attached to said top surface of said vehicle at an upper rear corner thereof such that the vertical plane of each such vertical support member is generally longitudinally aligned with respect to said vehicle, each of said vertical support members being configured to have a vertical extent above said top surface of said vehicle limited to be less than three inches, with a rearwardly trailing edge having a downwardly arcuate shape, a lowermost edge of each of said vertical support members extending rearward from said rear vertical transverse surface of said vehicle by substantially approximately three inches, each support member being limited to be entirely not lower than said top surface of said vehicle; and an arcuate scoop member, having an extent parallel to an axis of curvature thereof less than said width of said vehicle, said scoop member being attached to uppermost and rearmost arcuate edges of respective members of said plurality of vertical support members, said axis of curvature being disposed to be transversely orthogonal to a vertical longitudinal plane of said vehicle. A drag reducing subsystem for attachment onto a forwardly moving vehicle, traveling on wheels supported by axles, with an undercarriage structure, said subsystem comprising means, depending from and attached to an undercarriage structure of said vehicle, for enclosing said undercarriage structure within a housing extending substantially from a forwardmost longitudinal station that is non-interfering with operation of said vehicle to a rearmost longitudinal station proximate to, but forward from, a most forwardly disposed rear axle and wheel assembly of said vehicle, said housing having a transverse dimension substantially equal to a width of said vehicle and a vertical dimension depending from said undercarriage structure of said vehicle to a substantially horizontal planar surface defining thereunder a lower open area, thereby forming a partially enclosed volume, said housing including a substantially horizontal planar surface disposed below said vehicle, said housing being configured to deflect a volume of air overridden by a tractor associated with said forwardly moving vehicle, said air volume being deflected into portions passing along right and left vertical surfaces of said housing, respectively, and a portion passing longitudinally into the partially enclosed volume below said horizontal planar surface of said housing. A deflecting subsystem for attachment to a vehicle having a longitudinal side surface, a rear transverse surface and a rear corner therebetween, the rear side air deflecting subsystem comprising: an arm pivotably attached to the rear transverse surface of the vehicle, and having an arm operating position with respect to the rear transverse surface; a vane pivotably mounted to the arm, the vane having a vane operating position with respect to the arm, the vane being curved to deflect a flow of air passing along the longitudinal side surface of the vehicle across the rear transverse surface when the arm is in the arm operating position and the vane is in the vane operating position; an arm biasing means for rotatably biasing the arm about its pivot attachment into the arm operating position; and a vane biasing means for rotatably biasing the vane about its pivot attachment into the vane operating position.
