Embodiment Construction

[0033] figure 1 The truck 1 shown in has a rear area 2 in a conventional manner, the rear area 2 has two tailgates 3 that can The essentially box-shaped design with blunt ends leads to unfavorable aerodynamic properties. Thus, a rear spoiler arrangement 6 with two side spoilers 7 and two top air guiding elements 8 is provided, wherein one side air guiding element 7 and one each are arranged on each tailgate 3 Top air guide element 8. The tailgate 3 is hinged in a tailgate hinge 9 on the vehicle structure 10 or on the side 4 , respectively. The side air-guiding elements 7 and the top air-guiding element 8 are advantageously formed from a plastic sheet or a hard plastic surface and can be formed flat and flat or straight, or also curved slightly backwards, for example.

[0034] The rear spoiler arrangement 6 can advantageously be mounted only on the tailgates 3, so that a side spoiler 7 and a top spoiler 8 are mounted on each tailgate 3 respectively.

[0035] The rear spoile...

Abstract

The invention relates to a rear spoiler device (6) for a vehicle having at least one rear door (3), wherein the rear spoiler device (6) has an air-directing element (7), an adjusting device (12) for adjusting the air-directing element (7) between a folded-in basic position for opening the rear door (3) and an extended travel position for extending the contours and aerodynamic air conduction. It isprovided here that the adjusting device (12) is coupled to a door-side joint (15) and a spoiler-side joint (18) and has an intermediate joint (17) which is provided between the door-side joint (15) and spoiler-side joint (18) and in which said adjusting device is collapsible during the adjustment by changing an intermediate-joint angle (a) formed on the intermediate joint (17).

Description

technical field [0001] The invention relates to a rear spoiler arrangement for a vehicle, in particular a truck. Background technique [0002] Rear spoilers are used to improve the aerodynamics of vehicles, in particular vehicles with a box-shaped design and flat ends, such as trucks, and to reduce fuel consumption accordingly. They are installed in the rear region of the vehicle and generally have an air guiding element which extends the contour of the vehicle rearwardly, for example with a surface that is curved or straight or evenly extends rearward and towards the middle. Such a rear spoiler can be fastened, for example, to the roof or side walls of the truck. [0003] DE 20 2009 014 476 U1 and DE 20 2009 015 009 U1 show rear spoiler constructions in which the air guide element or the spoiler element is arranged displaceable or pivotable in order to enable different positioning of the vehicle door. Disturbed open. [0004] A swingable or reversible rear spoiler is usu...
