ACTIVE REAR WING SYSTEM

The active rear wing assembly consists of a rear spoiler motor (*5 in illustration), link mechanism (*3 in illustration), wing (*2 in illustration) and base plate (*4 in illustration).

2 Hall ICs are built into the rear spoiler motor (*5 in illustration). Each Hall IC sends pulse signals to the spoiler control ECU assembly to provide feedback on the position of the active rear wing.

The active rear wing extends via the following operations.

1. The rear spoiler motor (*5 in illustration) rotates the spindle bolt (*c in illustration) to move the spindle nut (*d in illustration) vertically.

2. The vertical movement of the spindle nut (*d in illustration) is converted into the rotational movement of the arms (*f in illustration) through the nut guide (*e in illustration) to rotate the arms at the center of the rod sub-assembly (*g in illustration), rotating the rod sub-assembly (*h in illustration).

3. The rotational movement of the rod sub-assembly (*h in illustration) is connected to the link mechanisms (*3 in illustration) to raise and retract the active rear wing. The link angle is restricted by stoppers, and after the stoppers are contacted, the rod sub-assembly (*h in illustration) is tightened to a specified angle to ensure wing rigidity.
