Abstract
Official abstract text for this publication.
An air deflector assembly for a vehicle includes a vertically translatable air deflector and linear actuators actuated in series by a driver to vertically translate the air deflector. The air deflector includes one or more rails configured for sliding translation within one or more cooperating vehicle-mounted tracks. A controller is operatively connected to the driver, and may be configured to vertically translate the air deflector to a predetermined position according to a vehicle rate of travel. The driver selectively causes the linear actuators to raise or lower the air deflector.
First claim
Opening claim text (preview).
What is claimed: 1. An airflow control system for a vehicle, comprising: a vertically translatable air deflector; a plurality of actuators actuated in series by a driver to vertically translate the air deflector; and a controller operatively connected to the driver, the controller comprising logic including executable instructions to translate the air deflector to a predetermined position according to a vehicle rate of travel. 2. The system of claim 1 , wherein the driver is a fluid driver. 3. The system of claim 1 , wherein the air deflector comprises one or more rails configured for sliding translation within one or more cooperating vehicle-mounted tracks. 4. The system of claim 3 , wherein the one or more rails are configured as T-channel sliders. 5. The system of claim 2 , wherein the driver is a hydraulic pump. 6. The system of claim 5 , wherein the hydraulic pump is reversible to cause the plurality of linear actuators to selectively raise or lower the air deflector. 7. The system of claim 6 , wherein each of the plurality of linear actuators is a hydraulic piston, the plurality of linear actuators in combination with the hydraulic pump defining a reversible hydraulic circuit. 8. A vehicle including the system of claim 1 . 9. An air deflector assembly for a vehicle, comprising: a vertically translatable air deflector; and a plurality of linear actuators actuated in series by a reversible hydraulic pump to vertically translate the air deflector. 10. The assembly of claim 9 , further comprising a controller operatively connected to the reversible hydraulic pump; wherein the controller comprises logic including executable instructions to translate the air deflector to a predetermined position according to a vehicle rate of travel.
