Description

Dual output actuator Background Exemplary embodiments of the present disclosure relate to dual output actuators, and more particularly, to dual output actuators with sequential operation. The active grille shutter system is located at the front end or head of the vehicle and is convertible between an open position and a closed position. When the louvers are in an open position, air may flow therethrough and into the engine compartment, thereby cooling the engine and/or radiator, as well as cooling a plurality of radiators/exchangers for air conditioning, turbo-or compressor-supercharged engines, oil coolers, etc. When the shutter is in the closed position, air is blocked and bypassed around the vehicle, thereby reducing aerodynamic drag and fuel consumption. Furthermore, warm-up time of the vehicle engine may be reduced during cold weather operating conditions. Thus, under certain operating conditions, when such cooling air is not required, it is necessary to close the shutter. Alternatively and as described above, other operating conditions may require opening the blind. However, current active grille shutter systems employ synchronous motion for each vane or shutter in the system. Thus, current active grille shutter systems are unable to open or close the vanes according to different zones (e.g., upper and lower zones). Furthermore, in some cases, closing all vanes or shutters of the system may not be the best solution to reduce aerodynamic drag. Because of the different operating conditions of different radiators, it is desirable to be able to selectively control different areas of the blind so that they can be actuated independently. In order to minimize complexity, weight and cost, it is not necessary to re-produce the active grille shutter system in parallel, and therefore it is desirable to provide an improved actuator for the active grille shutter system of the vehicle so that different active grille shutters can be controlled independently. Disclosure of Invention A dual output actuator for an active grille shutter system is disclosed, including a first output rotatably mounted about an axis, a second output rotatably mounted about the axis, the first output being independently rotatable about the axis relative to the second output and the second output being independently rotatable about the axis relative to the first output, and a gear rotatably mounted about the axis and capable of independently rotating either the first output or the second output by axial movement along the axis.
