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.

A drag reducing system, comprising:
- a flow restricting deflector couplable to a mount and positioned upstream in a path of airflow to an object, the flow restricting deflector comprising:
- a body portion;
- and
- a plurality of flow choking orifices extending through the body portion, each flow choking orifice having an inlet, an outlet, and an interior wall configured to provide a choked airflow condition.
A drag reducing assembly for a vehicle, comprising:
- a mounting bracket;
- a splash shield coupled to the mounting bracket, the splash shield positioned adjacent a wheel and tire combination of the vehicle;
- a flow restricting deflector coupled to and extending downwardly from the splash shield, the flow restricting deflector positioned upstream in a path of airflow to the wheel and tire combination, the flow restricting deflector comprising:
- a body portion;
- and
- a plurality of flow choking orifices extending through the body portion, each flow choking orifice having an inlet, an outlet, and an interior wall configured to provide a choked airflow condition.
