General information

The suspension is of independent hydropneumatic type. At the front, it comprises a vertically mounted hydraulic suspension strut unit, a lower suspension arm and an anti-roll bar. The suspension cylinders are supplied with hydraulic fluid from the main hydraulic system via the front height corrector which is actuated by the front anti-roll bar. The anti-roll bar is attached to the suspension arms with two links.

A trailing arm rear suspension system is used. The rear suspension cylinders are supplied with hydraulic fluid from the main system via the rear height corrector. As with the front, the height corrector is actuated by the rear anti-roll bar.

Ground height clearance is adjusted with a lever mounted inside the vehicle, the lever being connected by operating rods to the front and rear height correctors. Automatic damping is incorporated in the suspension cylinders.

Steering is of rack-and-pinion type,mounted on a crossmember attached to the front subframe. The steering column incorporates a universal joint and a coupling. Power steering is fitted to some models and this system incorporates a self-centring action which varies according to the speed of the vehicle. Power assistance is derived from a power-operated hydraulic ram cylinder mounted on the steering rack. The hydraulic pressure to the ram is supplied by the main suspension and braking system hydraulic circuit, the pressure being controlled by a flow distributor unit and a control valve.
