Abstract
Aerodynamic downforce is generated by an automobile diffuser located on the aft section of a motor vehicle's underbody. The upsweeping inclination of the diffuser ramp wall enables the expansion of airflow traveling through the diffuser to induce suction underneath the motor vehicle—thereby enhancing traction between the tires and road surface. However, moving (or rolling) the diffuser ramp wall in the airflow direction further increases suction and airflow speed underneath the vehicle and through the diffuser. As a result, downforce in-turn is enhanced.
Claims8
A rolling diffuser ramp for motor vehicle, comprising of a flat conveyor belt looped in tension around a driver and a driven pulley of equal size forming a moveable part of the rolling diffuser ramp, two cylindrical axle shafts that attach each of the driver and driven pulleys to bearing blocks on both sides, an electric motor mounted on one side of a stationary part of the rolling diffuser ramp near a kick point with its drive shaft connected to the driver pulley, wherein under rotational drive motion of the electric motor, the flat conveyor belt is rotated by the driver and driven pulleys, thereby underneath the rolling diffuser ramp, the rolling diffuser ramp moves in the direction of diffuser inlet to exit.
