Abstract
Aerodynamic device for a motor-vehicle including a panel structure located under the front part of the motor-vehicle and elastically biased towards a raised position and configured to be moved towards a lowered position due to an airflow which invests the motor-vehicle during travel. The aerodynamic device includes a bag structure provided inside of a cavity for receiving in its interior the airflow which invests the motor-vehicle during travel, in such a way that above a predetermined threshold value of the motor-vehicle speed, the bag structure is inflated and pushes the panel structure towards its lowered position.
Claims10
An aerodynamic device for a motor-vehicle, comprising:
- a panel structure located under a front part of the motor-vehicle and pivotally mounted around an axis transverse with respect to a longitudinal direction of the motor-vehicle, said panel structure being elastically biased towards a raised position and being adapted to be moved towards a lowered position when a motor-vehicle speed exceeds a predetermined threshold value, due to an airflow which invests the motor-vehicle, and
- an upper wall which is fixed with respect to a motor-vehicle body, and placed above said panel structure so as to define a cavity together with said panel structure,
- a bag structure arranged inside said cavity between said panel structure and said upper wall for receiving in its interior a portion of said airflow which invests the motor-vehicle during travel,
- wherein above said predetermined threshold value of the motor-vehicle speed, said bag structure is inflated and pushes said panel structure towards its lowered position;
- wherein said cavity vertically shrinks in a direction of a rear part of the motor-vehicle;
- and
- wherein a front part of said upper wall and a front part of said panel structure are vertically spaced form each other, while a rear part of said upper wall and a rear part of said panel structure are adjacent to each other, in such a way to provide for said cavity vertically shrinking in the direction of the rear part of the motor-vehicle.
