Construction of the subframe
The following general instructions complement the general instructions given in the general regula-
tions in Chapter 1. NOTE
3.1 Construction of the subframe
The purpose of the sub-frame is to ensure uniform distribution of loads on the vehicle chassis, sharing their resistance and rigidity
effects according to the specific vehicle use.
3.1.1 Material
In general, if stress on the sub-frame is not excessive, the sub-frame can be built with materials of poorer characteristics than
those used for the chassis, provided that it needs to be easily weldable and that it must not have values lower than those (1) shown
in Table 3.1.
Materials with better mechanical characteristics may be used when stress limits require them (e.g. in cranes), or if excessive section
heights are to be avoided. However, take into account that reducing the inertial moment of the reinforcing profile causes greater
flexion and stress on the main chassis.
The following are the characteristics of some materials taken into account for some of the applications described below.
