3-28 BUILDING & MOUNTING THE STRUCTURES E UROCARGO Euro 4/5 For the connections between the tanker body and subframe, we recommend using flexible elements (see Figure 3.19) at the front and rigid supports resistant to the longitudinal and transversal forces toward the rear. For road vehicles, we can generally consider that the first front flexible connection can, during the phase of torsion of the vehicle’s chassis frame, allow separation of approx. 10 mm between subframe and chassis frame. Tanks may be mounted directly onto the vehicle chassis without fitting an subframe under the following conditions:
- The distance between saddles must be determined depending on the load to be carried and must not exceed 1 meter. - Saddles must be fitted so as to allow an even distribution of the loads over a considerably large surface. Suitable brackets must be provided between the saddles to limit the longitudinal and transverse thrusts. - Other anchoring solutions may be authorised by Iveco. - Self-bearing tanks may be positioned directly on the chassis by means of suitable mountings located right behind the cab and in the area of the rear axle(s). The number and distribution depends on the number of axles and the wheelbase; this may vary from min.
2 for each side on 2- axle vehicles with short wheelbases to min. 3 for 3/4-axle vehicles with short wheelbases (see Figure 3.20). - The mountings must be sufficiently long (600 mm approx) and be positioned next to the suspension mountings (max. distance 400 mm). To permit the necessary torsional movements of the chassis, elastic front mounting should be used where possible. - Other solutions are possible depending on the type of construction.
