Problems solved by technology

In certain driving dynamic situations, the aerodynamic loads generated by the wing can be disadvantageous
For example, this load is disadvantageous for a change of direction between the opposite first and second bends, since there is a significant difference in the direction adjustment of the motor vehicle between the reclined position and the raised (upright) position, thus deteriorating the maneuverability of the motor vehicle

Embodiment Construction

[0037] refer to Figure 1 to Figure 9 , shows a mobile aerodynamic device 10 mounted on a motor vehicle 100 . The illustrated motor vehicle 100 is a rolling motor vehicle having a pair of front wheels 102 . It should be noted that the saddle-riding motor vehicle 100 may also be a two-wheeled motor vehicle, the two wheels being any type of front and rear wheels.

[0038] The aerodynamic device 10 comprises at least one wing 1 arranged on the front 101 of the motor vehicle 100 so as to be exposed to the air flow during movement. Actuating means 3 are also provided, adapted to selectively move the wing 1 about the axis of rotation 2 . In the figures, when the vehicle is in an upright position, the axis of rotation is depicted as horizontal, i.e. parallel to the ground T, as Figure 1 to Figure 9 shown. The axis of rotation 2 is perpendicular to the longitudinal center plane L of the motor vehicle 100 . From this, it can principally be identified: a stationary configuration A...

Abstract

An active aerodynamic device (10) for a motor vehicle (100) comprising at least a wing (1, 1') arranged in a front portion (101) of the motor vehicle (100) so as to be flowed by an air flow (F) during a forward movement of the motor vehicle (10); actuation means (3) configured to move said at least a wing (1, 1') about a rotational axis (2) substantially perpendicular to the midplane (L) of the motor vehicle (100). A saddle ride-type motor vehicle (100) comprising an active aerodynamic device (10).

Description

technical field [0001] The field to which the invention relates is that of two- or three-wheeled motor vehicles provided with a seat on which to ride, such as motorcycles and scooters, and also of so-called roll A longitudinally extending mid-plane rolling motor vehicle. A three wheel roll motor vehicle may include two front steered wheels and one rear drive wheel with a fixed axle. This roll motion allows the motor vehicle to tilt during travel, for example when navigating a bend. Background technique [0002] The application of aerodynamic accessories is known in the field of vehicles. In particular, accessories in four-wheeled vehicles such as automobiles generally have the shape of wings or fenders and are applied to the front or rear axle, but also to the sides in the middle. The main purpose of such attachments is to generate aerodynamic loads on the wheel, for example to improve the wheel's grip, stability and traction. An example is a Formula One car with a spoil...
