FLOW RESTRICTING DEFLECTOR

Abstract:

Drag reducing systems for vehicles are provided. In one aspect, a drag reducing system generally includes a flow restricting deflector couplable to a mount and positioned upstream in a path of airflow to an object. The flow restricting deflector generally includes a body portion and a plurality of flow choking orifices configured to provide a choked airflow condition. In another aspect, the drag reducing system is configured for positioning adjacent a wheel and tire combination of a vehicle upstream in a path of airflow to the wheel and tire combination. The flow restricting deflector may be coupled to and extending downward from a splash shield adjacent the wheel and tire combination.
