  • Patent number: 10625793
    Abstract: An aerodynamic structure attached to the sides and top of a truck cargo body (either a stand-alone trailer or a “straight truck” with the cab and cargo area as a fixed vehicle) at the aftmost region, which rear typically contains a rolling door assembly, which rolls upwardly. An aerodynamic structure is permanently attached to the sides and top of the trailer in a manner that extend past the aftmost plane of the truck cargo body and retract to the aftmost plane of the truck cargo body when subjected to a force, allowing this device to be backed into structures. The retracted orientation allows for the rear of the trailer to be fully accessible for loading and unloading, and does not reduce the size of the opening of the trailer. The various embodiments of the invention allow for automated deployment once the force used to compress the structure is removed.

  • Patent number: 8517452
    Abstract: A tractor-trailer fairing for blocking cross-winds is inexpensive, attaches to a forward face of the trailer, is adjustable to the gap between the tractor and trailer, and is easily moved between trailers. The fairing comprises two pairs of identical upper and lower curved panels independently attached to opposing front corners of the trailer. The panels slide down over pins attached to brackets permanently mounted to the trailer. Pairs of adjustable diagonal struts reach from a forward face of the trailer to each of the curved panels to hold the panels in position. Flaps attach to the forward edges of the panels at about a 90 degree angle and restricts the cross-winds from passing between the panels and tractor cab.

  • Patent number: 8496285
    Abstract: Adjustable aerodynamic devices are controlled to control the drag on a vehicle. In one form, control is accomplished in response to pressure from a plurality of pressure sensors. In another form, control is accomplished in response to air movement measurements, such as of wind speed and direction at a location that a vehicle has yet to reach. In another form, the position and location of air vortices between a cab and trailer can be determined and adjusted to adjust the drag by controlling aerodynamic devices.

  • Patent number: 8449017
    Abstract: A resilient strut adapted to secure an aerodynamic skirt to a trailer is provided, the aerodynamic skirt comprising a skirt panel including a front portion and a rear portion adapted to be substantially longitudinally mounted to the trailer, the skirt panel being adapted to move away from the aerodynamic configuration when contacting a foreign object and to recover its aerodynamic configuration thereafter, the resilient strut includes a shape variation adapted to change the mechanical strength thereof and also adapted to sustain an elastic deformation allowing the resilient strut to bend when a load is applied to the resilient strut when the skirt panel moves away from the aerodynamic configuration and to self-recover its original shape when the load is removed. A kit of resilient struts, a method thereof and a trailer equipped with same are also provided.

  • Patent number: 8444210
    Abstract: The present disclosure provides for drag reduction on a moving object through the atmosphere, thus increasing fuel efficiency. This is accomplished by attaching an inflatable boattail (i.e. drag reducer) to the aft face or rear end of a vehicle or trailer, thus delaying the flow separation to a point further downstream and mitigating the intensity of the negative pressure on the aft face.

  • Patent number: 8430447
    Abstract: A motor vehicle front spoiler has a spoiler lip (11) extending in the region of a front part of the motor vehicle over the entire width or part of the width of the front part. An actuating element (12) enables the spoiler lip (11) to be shifted between an extended operating position, in which the spoiler lip (11) forms a downwardly directed extension of the front part and acts as an aerodynamic air-guiding device, and a retracted inoperative position, in which the spoiler lip (11) is directed to the rear and essentially has no aerodynamic air-guiding effect. A portion (13) of the spoiler lip (11) that is at the bottom in the operating position of the spoiler lip (11) and is in the vicinity of the roadway can be replaced.

  • Patent number: 8276971
    Abstract: An aerodynamic structure for a vehicle that can effectively adjust airflow within a wheel house is provided. An aerodynamic structure (10) for a vehicle has an airflow collision wall (24) provided rearward, in a vehicle body longitudinal direction, with respect to a front wheel (15) in a wheel house (14), and extending in a vehicle width direction and facing a lower side in a vehicle body vertical direction, and an airflow guiding wall (22) hanging downward in the vehicle body vertical direction from a rear end portion (24A) in the vehicle body longitudinal direction of the airflow collision wall (24). The airflow guiding wall (22) extends in the vehicle body vertical direction, or extends in a tilting direction directed both toward the front wheel (15) side and toward the lower side in the vehicle body vertical direction.

  • Patent number: 8196995
    Abstract: A diversion apparatus, adapted to be arranged at the tail end of a vehicle, includes a diversion assembly and a slide mechanism. The inside of the diversion assembly is hollow and formed an airflow channel. The slide mechanism is arranged fixedly at the tail end of the vehicle body and has slot tracks extended along the lengthwise direction of the tail end of the vehicle body. The diversion assembly arranged on the slot tracks can be moved and slid thereon. Therefore, the diversion assembly can be slid on the slot tracks and moved toward the front of the vehicle body to prevent the opening of the door leaf of the vehicle from being hindered by the diversion assembly.

  • Patent number: 8196994
    Abstract: A vehicle's drag-reducing apparatus, adapted to be arranged at the tail end of a vehicle, includes a diversion body positioned at the lateral surface of the vehicle and a rotary piece. The airflow flowing across the lateral surface of the vehicle body is guided to the tail end of the vehicle by the diversion body. One end of the rotary piece is pivoted to the vehicle body, while another end is fixed to the diversion body. Rotating the rotary piece will bring along the diversion body to be abutted against the tail end of the vehicle body or to be moved to the position far away from the tail end of the vehicle body. Thereby, the opening of the rear door at the tail end of the vehicle won't be hindered, even where there is an arrangement of the diversion body.
