Parabolic suspension
Interventions are generally not allowed on this type of suspension.
Exception is made for outfits or special uses for which, in order to increase suspension rigidity, the application of rubber elastic
elements may be authorised.
In special cases and only after IVECO approval, the addition of supplemental sheets on the parabolic springs may be allowed; this
must be carried out by a specialised spring manufacturer.
Transformation of the suspension from mechanical to pneumatic (for the shop van fitting)
This type of transformation is strongly discouraged because it involves the suspension components and chassis coupling elements
essential for the active safety of vehicle.
The bodybuilder that intents to perform the intervention must present a detailed documentation to IVECO in order to obtain a
technical approval.
In case of installation of not original components, it is noted that any approval is issued on the basis of a specially planned evaluation
of their characteristics and without the contribution of specific tests, unlike when use of components of first use.
Therefore, for this particular type of transformation, IVECO shall be relieved from any liability that may be attributed to the new
component.
Stabiliser bars
In the case of an additional axle with air suspension, it might be necessary, depending on the solution adopted, to provide a stabiliser
bar, particularly when there is a superstructure with high centre of gravity.
Similar stability measures should be adopted for mixed suspensions on added rear axles.
Attachments to the chassis
The connections for the added axle to the chassis must be able to react directly on all the longitudinal and transversal forces
without transmitting them to the engine axle.
In the points of application of forces (spring supports, brackets for air springs, etc.), suitable crossbars or adequate reinforcements
to the chassis must be provided.
It is important to remember to create the correct orthogonality and alignment of the added axle, respectively, with the longitudinal
axle of the vehicle and with the drive wheel axle.
Check the special equipment available on the market.
Brake system
▶
Considering the importance for the active safety of the vehicle, extreme care must be given to
the braking system in both design and implementation.
The same type of braking units, pipes and couplings as on the original vehicle must be used on the added axle; in particular, the
braking unit must be of the type that equips the front axle.
For connection between the fixed parts (chassis) and the axle, it is advisable to use flexible pipes.
Direct connection is allowed between the braking section of the added axle and that of the engine axle.
Verify that the capacity of the air tank is suitable to the dimensions of the new added brake cylinders and, if necessary, mount an
additional air tank.
We recommend activating the parting brake on the added axle as well.
Keeping in mind the different gross vehicle mass determined with the intervention, the braking torque must be adjusted to the new
static and dynamic loads in order achieve even distribution of braking among the axles.
