摘要： A motorcar having excellent characteristics with respect to various aerodynamic problems over an ordinary motorcar running on an ordinary road, i.e. such air resistance and dynamic lift during an operation thereof that are lower than those in a conventional motorcar, and such an external appearance that is substantially not different from that of a conventional motorcar. A means for achieving this object consists of an air flow passage (4) which is provided in a hollow made by cutting a panel above the wheels, and which extends from a front air inlet portion (2) to a rear air discharge portion (3). The air passes without trouble through a non-panel-covered hollow space above the wheels, and advances smoothly toward the air discharge portion (3) which is higherthan or as high as the air inlet portion (2). Therefore, the air resistance and dynamic lift of the motorcar according to this invention can be reduced to levels lower than those of the air resistance and dynamic lift of a conventional motorcar. The airflow passage (4) is covered with a bonnet (16), and a reverse lift plate (5) and a reverse lift member (12) which are joined pivotably to an outer plate. These reverse lift plate (5) and reverse lift member (12) are fixed in harmony with the surrounding portions ofthe outer plate so that the height of the former is not different greatly from that of the latter. Therefore, the external appearance of the motorcar according to the present invention is substantially the same as that of a conventional motorcar.

摘要： A vehicle to be driven on a driving surface, comprising an engine cooling system with a grille, a radiator, and a fan. A bottom plate extends along a lower surface of the vehicle for covering the radiator. The bottom plate comprises a movable section coupled to an actuator mechanism for adjusting a ground clearance. The engine cooling system comprises flow guides mounted between the grille and the radiator, and an anti-recirculation cover mounted between the radiator and the bottom plate. The movable section is pivotable around a pivot axis directly downstream of the anti-recirculation cover. A controller is configured to control the actuator mechanism to adjust the ground clearance in dependence of a driving velocity.

摘要： A device for manoeuvring an aerodynamic flap (1) arranged on a motor vehicle, characterised in that it comprises mechanical means for shifting the flap from a retracted position to a deployed position, successively performing a movement extending the flap while keeping the plane of the flap parallel to the direction of an air stream flowing around the flap when the vehicle is moving, such that the aerodynamic pressure exerted on the flap is substantially zero, and then a movement pivoting the flap about a pivot axis (AA') located in a plane of the flap and passing substantially through a centre of aerodynamic thrust (10) of the flap, such that the torque applied to the pivot axis (AA') and resulting from the aerodynamic forces is substantially zero. The shift from a deployed position to a retracted position is carried out by performing said movements in reverse order.

摘要： 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.

摘要： An active front deflector assembly having a deflector panel, actuator, and linkage assemblies each with a predetermined geometry and ratio of links to each other for movement of the active front deflector assembly between at least a deployed position and a retracted position. The deflector panel is positionable at multiple heights. The assembly deploys and retracts based on vehicle requirements, and, when deployed, redirects the air flow in the front of the vehicle to improve the vehicle aerodynamics for either fuel economy or performance characteristics. Additionally, it allows for the deflector panel to retract so the vehicle meets ground clearances, etc. The deflector panel is also both rigid and semi-rigid to absorb impact energy. A drive shaft transmits the drive from one side to the other side. The deflector is both rigid and semi rigid to absorb impact energy.

摘要： A front structure of a saddle ride type vehicle includes a headlight unit, a front cowl, and a middle cowl. At a position outside the headlight unit in the vehicle width direction, an air intake portion opening to the front side of the vehicle is formed between the front cowl and the middle cowl. The front cowl includes a partition wall configured to divide the air intake portion into an upper region and a lower region. The lower region forms an inlet of an air intake path of an air cleaner. The upper region forms a first wind guide path configured to discharge a traveling wind to the rear side of the front cowl.

摘要： 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.

摘要： An active front deflector assembly having a deployable deflector panel, linkage assemblies, and an actuator. The system deploys and retracts based on vehicle requirements, and, when deployed, interrupts air flow thereby improving the vehicle aerodynamics, reducing emissions and improving fuel economy. The deflector panel is retractable so the vehicle meets ground clearances, ramp angles, off-road requirements, etc. The deflector panel is also both rigid and semi-rigid to absorb impact energy. The linkage assemblies are coupled to the deflector panel and a drive shaft connected to the actuator. The drive shaft transmits the drive from the actuator coupled to one linkage assembly to the other linkage assembly for moving the deflector panel between the deployed/retracted positions. The actuator is clutched to prevent damage to the system. The active front deflector assembly provides a fully deployable system with object detection, declutching of the actuator, and communication with the vehicle.
