Top Actuation System

TOP ACTUATION SYSTEM

The top actuation system consists of two mechanically coupled electric motors, each driving a swivel gear unit on each side by way of a flexible shaft.




A steering arm, mounted on the gear shaft, transmits the necessary movement to the top linkage.




The drive motors are screwed to a mounting plate and installed in a recess in the rear bulkhead behind the rear seats.

They are accessed by removing the rear bulkhead trim and lifting up the insulation.




The flexible drive shafts are plugged into the motor shafts, bonded and additionally secured by means of a clip.
