Embodiment Construction

[0034] In the description, the same elements are identified by the same reference numerals.

[0035] In this specification, "upstream" is intended to mean that an element is placed before another element with respect to the flow direction of the air flow. Conversely, "downstream" is intended to mean that an element is placed after another element with respect to the direction of flow of the airflow. The terms "top", "bottom", "top" and "bottom" refer to the arrangement of elements in the figures, which generally corresponds to the arrangement of elements in an installed state in a motor vehicle.

[0036] The following examples are examples. Although the description refers to one or more embodiments, it does not necessarily mean that every reference refers to the same embodiment or that the feature is only applicable to one embodiment. Individual features of various embodiments may also be combined or interchanged to create other embodiments.

Abstract

The invention relates to an aerodynamic deflector device (7) for a wheel of a motor vehicle, comprising: a long support (11) designed to be mounted on a motor vehicle; a deflecting wall (15) mounted such that it is movable on a support (11) between a retracted position in which the deflecting wall (15) is raised in relation to the support (11) in the mounted state, and a deployed position in whichthe deflecting wall (15) is lowered in relation to the support (11) in the mounted state; and an actuator (19) designed to move the deflecting wall (15) between the retracted and deployed positions.According to the invention, the deflecting wall (15) is mounted such that it can be rotatably moved on the support (11) about an axis of rotation (17) oriented substantially parallel to a longitudinalaxis of the support (11) and driven by the actuator (19).

Description

technical field [0001] The invention relates to a motor vehicle wheel aerodynamic deflection device. Background technique [0002] A continuing concern in the automotive sector is the fuel consumption and ecological impact of vehicles, in particular due to their emission of greenhouse gases such as CO2 or due to toxic gases such as NOx, for example. In order to reduce fuel consumption, car manufacturers have been trying to make propulsion engines more efficient on the one hand and reducing the consumption of vehicle equipment on the other. [0003] An important factor in vehicle consumption depends on the wind load or aerodynamics of the vehicle. [0004] In particular, the aerodynamics of a motor vehicle is an important characteristic, as it affects in particular the fuel consumption (and thus pollution) and performance of said vehicle, especially acceleration. [0005] In particular, the drag resistance or aerodynamic resistance of forward travel plays a decisive role, e...
