Embodiment Construction

[0019] Referring to the drawings (wherein like reference numerals refer to like components), figure 1 A schematic view of motor vehicle 10 positioned relative to road surface 12 is shown. Vehicle 10 includes a vehicle body 14 disposed in a body plane P substantially parallel to road surface 12 . The vehicle body 14 sets six body sides. The six body sides include a first body end or front end 16, an opposite second body end or rear end 18, a first transverse body side or left side 20 and a second transverse body side or right side 22, the body top including the roof 24 and an underbody section (not shown).

[0020] The left side 20 and the right side 22 are generally parallel to each other and are disposed relative to the imaginary longitudinal axis X of the vehicle 10 and span the distance between the front end 16 and the rear end 18 . A body plane P is defined to include said longitudinal axis X. A cabin (not shown) of the vehicle 10 is generally bounded by a front end 16...

Abstract

A splitter system for a vehicle includes a splitter body having a first splitter body side section and a second splitter body side section. The vehicle includes a vehicle body disposed along a body longitudinal axis and having a first vehicle body end configured to face an incident ambient airflow. The splitter body is mounted at the first vehicle body end to generate aerodynamic downforce on the first vehicle body end when the vehicle is in operation. A mechanical device configured to selectively and individually displace each of the first diverter body side section and the second diverter body side section relative to the first vehicle body end. Said displacement of the splitter body side sections by means of mechanical means in turn adjusts the aerodynamic downforce generated by the splitter body side sections on the first vehicle body end.

Description

technical field [0001] The present disclosure relates to an active splitter for enhancing the aerodynamics of a motor vehicle. Background technique [0002] Aerodynamics are an important factor in vehicle design, including cars. Automotive aerodynamics is the study of the aerodynamics of road vehicles. The main objectives of the research were to reduce drag and wind noise, minimize noise emissions, and prevent unexpected lift and other aerodynamic instability at high speeds. In addition, the study of aerodynamics can also be used to achieve downforce in high-performance vehicles to improve vehicle traction and cornering ability. This study is typically used to shape vehicle bodies to achieve the desired compromise among the above characteristics for a specific vehicle application. [0003] A splitter is an aerodynamic device used to increase downforce at the front of a car. Typically, stagnation of the incoming airflow is caused by the air dam in front of the vehicle abo...
