AERODYNAMIC DEVICE TO BE FASTENED UNDER A VEHICLE, AND VEHICLE EQUIPPED WITH SUCH AN AERODYNAMIC DEVICE

摘要

The invention relates to an aerodynamic device (1) suitable to be fastened under and to extend downwards from a vehicle (2), near the vehicle front face (10). The aerodynamic device comprises: - one central spoiler (20) having a front wall and two side walls extending rearwards from the front wall side ends; - two lateral spoilers (40), each lateral spoiler having a front wall as well as an outer side wall and an inner side wall each extending rearwards from a front wall side end; In the operative position of the aerodynamic device, the inner side wall of each lateral spoiler (40) substantially faces a corresponding side wall of the central spoiler (20) and forms a channel (50) having a substantially longitudinal axis and having a width - along a transverse direction (Y) - which decreases from its front end to its rear end, so that said channel (50) is capable of canalizing and accelerating air flowing under the vehicle (2) substantially longitudinally from the channel front end towards its rear end. The invention further relates to a vehicle equipped with such an aerodynamic device.
