Abstract:
An air guiding device for a motor-vehicle comprises a main chamber (9) located at the rear of a front wall (2A) of the motor vehicle, and defined between said front wall (2A), a rear wall (11) which is spaced apart from said front wall (2A) and two side walls (103). At least a first opening (5) is provided on said front wall (2A), for the inlet of air into said main chamber (9), while at least one second opening (12) on said rear wall (11) guides the air into the engine compartment (6) of the motor-vehicle. Two side ducts (18) are each extending from an inlet (19) located on a respective side wall (103) of the main chamber (9) to an outlet (20) giving out on a respective outer side wall (2B) of the motor-vehicle. To said second opening (20) there is associated a device (13) for controlling the air flow therethrough. The outlets (20) of the two side ducts (18) are arranged and oriented so as to generate a substantially flattened and vertical air curtain adjacent to each front wheel (W) of the motor-vehicle on the outer side thereof.
Abstract:
An aerodynamic device (1) provided under the body of a motor vehicle comprises a panel structure (2) movable between a raised position and a lowered position. The panel structure (2) includes a front spoiler (3) pivoted to the motor-vehicle bumper adjacent to the front edge of the front spoiler, and a main panel (4) having its front edge resting on the rear edge of the front spoiler (3) and its rear edge pivoted to the motor-vehicle structure. The front spoiler (3) is elastically biased upwardly, against the main panel (4). A leaf spring (5) tends to hold the main panel (4), and hence the front spoiler (3) in the lowered position. The device further comprises a winding shaft (7) for winding lifting cables (9) for lifting the main panel (4). The shaft (7) is rotatably mounted around the transverse axis and is controlled by an electric motor (M). The main panel (4) has an aperture (12) controlled by a shutter panel (13) which is moved towards an opened position when the main panel is brought to its raised position, adjacent to the motor-vehicle exhaust conduit.
