ABSTRACT:
A cavity forming structural support assembly for a chassis element of an internal combustion engine incorporates an elongated member made of metal or fiber reinforced plastic material having a peripheral wall with a plurality of internal longitudinally extending wall portions defining a longitudinally extending cavity and further including a plurality of secondary longitudinal cavities at least partially surrounding the primary cavities. The elongated member is capped by a material different than that of the elongated member to form a respective end thereof and to include transverse walls forming cavities within the elongated member and enclosing the secondary longitudinal cavities. The respective caps include a portion extending inside the walls of the hollow section chamber and in pressing engagement therewith. A support member extends transversely into the primary cavity and is connected to the inner wall portion of the cap. Fluid is permitted to flow through the elongated member via the cavity and the secondary longitudinal cavities.
