Embodiment Construction

[0018] see figure 1 As mentioned above, it is known to provide a motor vehicle 10 comprising an aerodynamic front spoiler 12 disposed substantially adjacent to and below a vehicle bumper 14 to control air flow under the vehicle 10 (see arrow). The wind baffle 12 reduces the airflow under the vehicle, thereby reducing the tendency for the nose to lift when the vehicle is traveling at speed. Likewise, through the use of translatable baffles 12 in various configurations, airflow under the vehicle can be increased or decreased as desired to help cool underbody components.

[0019] Also as mentioned above, when driving on uneven roads or when encountering obstacles on the road, any sudden reduction in ground clearance may cause the wind deflector to strike the road or obstacle, resulting in damage to the vehicle and Possible loss of stability and handling. Even if the vehicle does not actually hit an obstacle in the road, sudden hard braking or steering can cause the nose of the...

Abstract

A front baffle assembly for a vehicle, comprising: a translatable front air deflection panel for varying air flow under the vehicle; a deployment mechanism for shifting panels; a quick lift mechanism for rapidly lifting said front air deflection panels from one or more deployed positions. A controller in operative communication with the deployment mechanism and the quick-lift mechanism controls the operation thereof. At least one sensor is included for sending a signal indicative of road or vehicle conditions to the controller. A locking mechanism is provided under control of the controller for locking the front air deflection panel in the raised position or the deployed position or positions.

Description

technical field [0001] The present disclosure generally relates to front spoilers for motor vehicles. More specifically, the present disclosure relates to an aerodynamically translatable front spoiler that can be raised rapidly to prevent contact with road obstacles or road surfaces. Background technique [0002] As the speed at which a motor vehicle is traveling increases, lift is created and the nose of the vehicle lifts slightly due to the difference in air velocity and pressure created under the chassis of the vehicle relative to the roof of the vehicle. This affects handling and stability, especially in vehicles operating at higher speeds. The effects on handling and stability are exacerbated in front-wheel drive vehicles. To address this problem, it is known to provide aerodynamic front air dams for motor vehicles to assist in controlling air flow. Motor vehicle fuel efficiency and passenger compartment acoustics may be improved through the use of a front spoiler. ...
