The Roof's Link System
The electrically convertible hardtop has a link system to which the front (1), center (2) and rear (3) roof sections and the parcel shelf (4) are connected.
The main links arms (5) are connected to the body at the rear edge. The center roof section is fixed to the main link arms. The front roof section sits on link arms (6) that are articulated to the main link arms. The rear roof section is also fastened to link arms (7) that are articulated to the main link arms.
The movement of the center and rear roof sections is generated by the link arms being actuated by two hydraulic cylinders known as the master cylinders. The movement of the front roof section is generated by two other hydraulic cylinder, known as the front roof cylinders.
The convertible roof module (CRM) regulates roof operation.
