Abstract: An aerodynamic device suitable to be fastened under and to extend downwards from a vehicle, near the vehicle front face includes one central spoiler having a front wall and two side walls extending rearwards from the front wall side ends, and two lateral spoilers, 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 substantially faces a corresponding side wall of the central spoiler and forms a channel having a substantially longitudinal axis and having a width along a transverse direction which decreases from its front end to its rear end, so that the channel is capable of canalizing and accelerating air flowing under the vehicle substantially longitudinally from the channel front end towards its rear end.

Abstract: A rear aerodynamic device for a vehicle and vehicle equipped with such a device are provided. The aerodynamic device can be fastened under a rear end of a vehicle frame of a cargo body of an industrial vehicle, behind the wheels. It includes a nozzle having an inlet positioned on a lateral external face of the device and capable of canalising air flowing along the vehicle and an outlet positioned at the rear part of the device and capable of ejecting the air flow underneath a vehicle rear face.
