Embodiment Construction

[0055] The following embodiments are examples. Although the specification refers to one or more embodiments, this does not necessarily mean that every reference refers to the same embodiment, or that a feature applies to only one embodiment. Individual features of various embodiments can also be combined or interchanged in order to create other embodiments.

[0056] The horizontal plane is represented by the reference coordinate system (X, Y), the vertical direction is represented by the direction Z, and the three directions form a trihedron (X, Y, Z). These axes may correspond to the names of the axes in a motor vehicle, that is, in vehicles, by convention, the X axis corresponds to the vehicle's longitudinal axis, the Y axis corresponds to the vehicle's transverse axis, and the Z axis corresponds to the height of the vehicle. vertical axis.

[0057] In this description, the terms "vertical / horizontal" or "top / bottom" refer to the orientation of elements in the drawings, wh...

Abstract

Deflector device (7) for a motor vehicle wheel (3), comprising at least one aerodynamic region (4, 400, 401) designed to be exposed to an external air flow (10), the device (7) further comprising an articulated mechanism (21) for moving the at least one aerodynamic region (4, 400, 401) so as to allow the deflector (7) to move from the retracted position to the deployed position, said articulated mechanism (21) comprising a drive member (22), and said articulated mechanism (21) being arranged to move the drive member (22) translationally when the deflector device (7) moves from the retracted position to the deployed position, the deflector device (7) comprising an actuator (19) configured to control the articulated mechanism (21) so as to allow the aerodynamic regions of the deflector to move relative to each other, said deflector device (7) further comprising a security device (50) configured to return said deflector device (7) to the retracted position without intervention by the actuator (19).

Description

technical field [0001] The invention relates to a deflection device for a wheel of a motor vehicle, said deflection device also comprising a safety device. The invention also relates to a vehicle provided with such a deflection device. Background technique [0002] The automotive industry has always been concerned with fuel consumption and the ecological impact of vehicles, especially due to their emission of greenhouse gases such as carbon dioxide or due to the ecological impact of toxic gases such as nitrogen oxides. To reduce fuel consumption, automakers have been trying to make jet engines more efficient and reduce the consumption of equipment on vehicles. [0003] An important factor in vehicle consumption is determined by wind loads or the aerodynamics of the vehicle. [0004] In particular, the aerodynamics of a motor vehicle is an important feature, since it particularly affects the fuel consumption (and thus pollution) and performance, especially acceleration, of ...
