DESCRIPTION

All versions are equipped with power steering.

This steering system guarantees:

steering safety and precision at high speeds

good handling

limited effort during parking manoeuvres and at low speeds.

The telescopic type steering column in two sections contributes greatly to the resistance of the vehicle in all types of frontal impacts.

• 1, Lower column
• 2, Upper column
• 3, Magnesium support
• 4, Steering wheel
• 5, Friction bush
• 6, Spring
• 7, Power assisted steering box
• 8, Cooling coil
• 9, Steering rods
• 10, Flexible element
• 11, Power assisted steering pump
• 12, Power assisted steering fluid reservoir

The steering column consists of:

a lower collapsible section (1) which allows the position of the steering wheel (4) to remain fixed in the case of a frontal impact

an upper section (2) supported by a steel bracket and a magnesium support (3) which prevent vibrations of the steering wheel (4).

With the advantage of:

increasing the passive safety of the vehicle

improving driving comfort.

The steering column slides for the axial adjustment and moves in a rocking motion for the vertical adjustment.

The steering lock is the "friction" type in accordance with the regulations governing the prevention of break-in attempts.

This system consists of a bush (5) and a spring (6) fitted on the upper steering column (2).

The spring has a "smooth part" on the outside and a "toothed part" on the inside.

The toothed part is a press fit on the upper shaft bearing down slightly on the surface and preventing sliding in relation to the shaft.

The smooth part is a press fit on the inner diameter of the friction bush (5) and can slide in relation to the bush with a controlled torque (between 10 and 24 daNm).

The function of the friction system limits the maximum force which can be transmitted and guarantees the following in the case of a theft attempt:

the security of the steering column

impossibility of lock mechanism breakage

with the advantage of ensuring:

the anti-theft function

driving safety.

The power asssisted steering box (7) has oversize racks and rods to:

limit the flexible yield of the steering line

guarantee improved driving precision.

The following have been adopted to minimize the hydraulic pulses of the power assisted steering sysem which can produce noise:

longer high pressure fluid pipes with an improved shape and internal resonators

power assisted steering fluid cooling coils (8) which prevet cavitation.

The cooling coil is connected to the relevant pipes by rapid attachment couplings.

The steering rods (9) are equipped with a flexible element (10) to dampen the vibrations due to the kinematic effect of the suspension, with the advantage of eliminating the vibrations at the steering wheel in the different steering conditions.
