摘要:
An air dam for an automotive vehicle has panel wherein the panel extends vertically down from a bottom of a bumper of the vehicle when in the deployed position. The panel has at least one openable and closable air flow opening therein. In an aspect, each air flow opening opens to a mouth of a duct that extends rearwardly form the panel. In an aspect, the panel has a plurality of air flow openings and ducts. In an aspect, the air dam is a deployable air dam.

A fairing includes a prow portion having a pointed leading end adjacent an undercarriage and an aft trailing end. The trailing end extends across the undercarriage and vertically spans the space from the height of the undercarriage to the ride height of a vehicle. A support under the fairing resiliently maintains the prow portion in the shape of a boat hull prow, The fairing may present a curved boat hull shaped transition from the leading end to the trailing end, it may have chine spanning the prow portion from the leading end along a midpoint, or may be made of multiple panels and chines. The prow portion has vertical sides toward the trailing end, which terminate in vertical edges near the vehicle's tires. The fairing may include enlarged areas to increase aerodynamics near the tires, and may include scoops and a spoiler to help laminate turbulent air.

摘要:
A system and method aerodynamic fairings including a gap fairing. The gap fairing includes multiple panels. The multiple panels are interconnected utilizing connectors to form a half conical shape extending from a front portion of a trailer. The gap fairing also includes supports connected to the multiple panels through support structure of the trailer.
摘要:
An under trailer aerodynamic control system that increases air mass, organization and velocity with forward mounted airflow modifying directional panels and a rear airflow modifier mounted in a firm and movable manner for location near the underneath side of a truck trailer forward of the trailer tires and axles to better manage airflow around the trailer tire and axle assembly. In operation, the rear mounted airflow modifier collects the airflow from the forward mounted modifiers and routs impinging air to exit between the trailer tires and well past the end of the trailer for controlled road spray and splash while keeping tires and brakes running cooler and decreasing parasitic drag of the trailer as it moves along the highway while reducing driver fatigue due to improved handling characteristics.
摘要:
A car having a frame, which supports a pair of front wheels and a pair of rear wheels, a passenger compartment, at least one pair of doors, and an underbody which delimits the car on the lower side, faces the road surface, and has an aerodynamic diffuser, which is arranged in a rear position and is provided with a chute having a height with respect to the road surface that progressively increases when longitudinally moving from the front to the rear. The underbody can include a pair of aerodynamic channels, each of which extends longitudinally, leads to the aerodynamic diffuser, is open on the lower side towards the road surface, has a shape of an upside-down “U” in its transverse section and is open underneath towards the road surface and has, in its transverse section, an area that progressively increases when longitudinally moving from the front to the rear.

A motor vehicle (1) has a device (5) that projects into the wheel house (3) to reduce the flow of air into the wheel house (3) while the motor vehicle (1) is moving. The device (5) may extend from an underbody panel (4) of the motor vehicle (1) and may be pivotable about a longitudinal axis (6) of the motor vehicle (1) on a side of the underbody panel (4) that faces the wheel house (3). Alternatively, the device (5) is connected to a chassis component (7) of a wheel (2) arranged within the wheel house (3).
摘要:
An underside cooling arrangement and method for a vehicle includes an underside component mounted to the underside of the vehicle, and an airflow directing member that directs airflow generated when the vehicle is moving in a forward direction to a location rearward of the underside component. The airflow that is directed to the location rearward of the underside component creates a vacuum that draws an auxiliary airflow near the underside component for cooling thereof.
