Abstract
Disclosed herein is an actuator for an active air flap apparatus which may manually open air flaps during an actuator failure and may prevent the opened air flaps from closing using e.g., vehicle induced wind. The apparatus includes a worm gear that is driven by the power of a motor and a spur gear that is configured to transmit rotary force of the worm gear towards the air flaps.
Claims3
-4. (canceled)
An actuator for an active air flap apparatus, the actuator comprising:
- a worm gear driven by the power of a motor;
- a spur gear configured to transmit rotary force of the worm gear towards air flaps,
- wherein the worm gear has a plurality of teeth each having opposite faces symmetrically inclined at an inclined angle relative to an axially longitudinal direction of the worm gear,
- wherein the spur gear has a plurality of teeth engaged with the teeth of the worm gear and each having opposite faces symmetrically inclined at substantially the same inclined angle as that of the worm gear, relative to a tangential direction of the spur gear, and
- a stopper disposed in an actuator housing and configured to restrict the worm gear from moving in one direction.
