Problems solved by technology

[0014] Another problem with the three embodiments of U.S. Patent No. 6,974,178 is that the underside of the body part of the vehicle cannot be accessed if required for some work, such as maintenance or management of components.
[0015] Yet another problem with the three embodiments of US Patent No. 6,974,178 is that there is still a region of high turbulence caused by the exhaust airflow and to which the passing airflow is sensitive, which adversely affects the aerodynamic behavior of the vehicle

[0061] Figure 2-4AAn exemplary first embodiment of a trailer 3 for the invention is shown having aerodynamic drag reduction means such as straight longitudinal guides 31 and 38 . The aerodynamic device can be described as a combination of two thin-walled plates, with a horizontal lower edge 32 , a vertical rear edge 33 , a horizontal upper edge 34 and a vertical front edge 35 in the case of the left longitudinal deflector 31 , and with a right longitudinal deflector 38 In other words, there is a horizontal lower edge 39, a vertical rear edge 40, a horizontal upper edge 41 and a vertical front edge 42. The starting point of the frontmost edges 35 and 42 of the longitudinal guide bodies 31 and 38 is located further away from the lower horizontal front edge 19 of the body volume 4 of the trailer 3 . The rear edges 33 and 40 of the longitudinal guide bodies 31 and 38 reach the lower rear edge 20 of the body volume 4 of the trailer vehicle 3 . Left and right deflectors, designat...

Abstract

The present invention relates to a device for minimizing the aerodynamic drag that results when tractors, trailers, rigid trucks, lorries, and other vehicles are moving through air. In particular the invention relates to a plate-shaped flow conductor (31) having a front edge, a lower edge, a rear edge and an upper edge. The flow conductor is mountable along the upper edge (34) in a substantially vertical position to a body portion of a pulled vehicle of a vehicle combination of at least two pivotally connected vehicles. When mounted the flow conductor extends at least partially under the bodyportion in a longitudinal- direction of the1 pulled vehicle. Characteristic for the flow conductor according to the invention is that the flow conductor comprises locally in conjunction with the front edge a thickened portion (78,85), which has a streamlined outer contour (83,84) in a cross section transversally to the front edge.

Description

technical field [0001] The present invention relates to deflectors for minimizing aerodynamic drag produced by tractors, trailers, monocoque trucks, trucks and other vehicles as they move through the air. In particular, the invention relates to a plate-shaped deflector for use as a side skirt, having a front edge, a lower edge, a rear edge and an upper edge. The deflector is mountable to an outer lower edge of a body portion of a towed vehicle of a vehicle combination of at least two pivotally coupled vehicles in a substantially vertical position along the upper edge. When mounted, the deflector extends at least partially outside the lower body portion in the longitudinal direction of the towed vehicle. The deflectors acting as side skirts reduce aerodynamic drag and also reduce noise and rain splash from the wheels. Background technique [0002] It is a well-known fact that the aerodynamic performance of the external shape of a vehicle and its movement in a medium can be ...
