Connections between frame and counterframe
3.3.3 Connection with brackets (flexible joint)
Some examples of this type of connection are shown in Figure 3.8 and 3.9.

To ensure elasticity of the connection, before tightening the screws the distance between chassis and sub-frame shelves must
be 1 to 2 mm; greater distances must be decreased by using suitable shims. When tightening the screws, the shelves must come
into contact.
Using bolts of proportional length improves the flexibility of the connection.
The brackets must be secured to the web of the vehicle’s side member only by means of bolts or rivets.
In order to better sustain transversal loads, usually the shelves are applied so that they protrude slightly in the vertical direction with
respect to the upper edge of the chassis. If the shelves must be exactly flush, the side guide of the structure must be anchored in
other ways (e.g. using guide plates connecting only to the sub-frame or to the vehicle chassis, see Figure 3.10). When the front
connection is elastic (see Figure 3.9), the side containment must be ensured also when the chassis is at maximum torsion conditions
(e.g. driving off-road).
If the vehicle chassis is already fitted with shelves to connect a tray of a type approved by IVECO, these shelves must be used to
that purpose. Shelves applied to the sub-frame or structure must have resistance characteristics no lower than those originally fitted
on the vehicle (see Table 2.7 and Table 3.1).
