ACTIVE AIR FLAP SYSTEM OF VEHICLE

摘要

An active air flap system for a vehicle includes a duct allowing ambient air to flow into an engine compartment, a motor in the duct to generate driving force and having a hinge shaft configured to transmit the generated driving force, and a flap coupled to the hinge shaft of the motor to regulate a degree of opening and closing of the opening, and released from the state of being coupled to the hinge shaft of the motor when power supply to the motor is cut off, to open the opening. When power is not applied to the motor of the active air flap system due to an abnormal reason, the flap is separated from the motor so as to be prevented from being stuck due to fault of the motor resulting from an abnormal reason or due to a dead battery.
