Patent Images
1. A system for reducing the air resistance of a truck, comprising:
- the truck comprising a cargo space that is bounded at a bottom by a loading floor and in height by a roof wall spaced apart from the loading floor, wherein the roof wall is adjustable in height relative to the loading floor, wherein a cargo height recognition module is provided, which recognizes and determines an actual height of loading and wherein the cargo height recognition module automatically performs the height adjustment of the roof wall, wherein the height of the roof wall is adapted to be reduced by the cargo height recognition module to a lower level corresponding to a height of loaded freight units.

Abstract
A system for reducing the air resistance of a truck, particularly an articulated vehicle, wherein the vehicle comprises a cargo space that is limited downward by a loading floor and in the height thereof by a roof wall spaced apart therefrom. The aim is to provide a system that minimizes the face area of the truck and thus the fuel consumption in dependence on the actual cargo space used. According to one embodiment, the roof wall is height-adjustable opposite the loading floor.
