Abstract: A chassis mounted energy extraction and delivery system. In one embodiment, a gravity-referenced, external tire inflation facility is integrated into an aerodynamic fairing mounted on the chassis of a vehicle. In one other embodiment, a torsion bar coupled between a hub-mounted energy extraction or delivery facility and a selected portion of the chassis provides a cross-referenced fixed point of reference. In a dual-axle embodiment, a first end of the torsion bar is coupled to the hub of one axle and a second end of the torsion bar is coupled to the hub of the other axle. In a single-axle embodiment, the second end of the torsion bar is coupled to the chassis.

Abstract: Systems and methods for controlling movement of a mudflap hanger arm, to reliably return from a deflected position to a resting position, while providing improved manufacturability and reduced corrosion and wear through the use of guidance surfaces on a mounting plate and a frame seat that form the interface between the hanger arm and a vehicle frame. When the hanger arm pivots about an axis on one side of the mounting plate and frame seat, guidance surfaces on the opposite side are in contact or near-contact, preventing the mounting plate and frame seat from being laterally displaced or rotated with respect to each other. The improved mounting plate and frame seat can reduce or eliminate manufacturing operations such as welding, coating, etc., reducing the cost of the apparatus, while enhancing manufacturability and operation.

Abstract: Embodiments provide an aerodynamic fairing system that may comprise a base configured to mount to a vehicle, an arm coupled to the base at a proximate end and extending laterally, and a fairing mounted to the arm having an inboard and an outboard surface. The fairing outboard surface may provide an aerodynamic outer surface to direct flow to an angle to the rear. The arm may a fixed or adjustable length arm. The arm may provide a mounting area for a mud flap such that aerodynamic system may act as a mud flap hanger. Embodiments also provide an adjustable mud flap hanger.

Abstract: Embodiments provide an aerodynamic toolbox assembly comprising a toolbox coupled to a tractor trailer and an aerodynamic fairing assembly coupled to the toolbox. At least one fairing component extends beyond a selected surface of the toolbox to facilitate aerodynamic air flow past the toolbox during normal operation of the trailer.

Abstract: One embodiment comprises a fairing assembly adapted to couple to a vehicle, the assembly comprising: a support arm mountable to a frame rail of a vehicle and a fairing adapter adapted to mount a fairing to the support arm. The fairing adapter is rotatably coupled to the support arm and is rotatable from a first orientation corresponding to an aerodynamic position to a second orientation corresponding to a first access position. The fairing adapter may also be rotatable to a third orientation corresponding to a second access position. The assembly further comprises a releasable lock to lock the fairing adapter in the first orientation and releasable to allow the fairing adapter to rotate to the second orientation or the third orientation.

Abstract: In some embodiments, a system and/or method may include a fairing system for vehicles. The fairing system may include a roofing extender. The roofing extender may be couplable rearward of a roof of a vehicle. In some embodiments, a frontward portion of the roofing extender may be coupled to the roof of the vehicle such that the roofing extender pivots, at the frontward portion, relative to the roof of the vehicle. In some embodiments, a rearward portion of the roofing extender may be coupled to the vehicle with a resilient member which allows the roofing extender to pivot relative to the roof of the vehicle within a specified range as needed before returning to set start point. In some embodiments, the roofing extender functions to adjust airflow over the roof of the vehicle.
