The invention discloses a front wall assembly of a heavy truck. The front wall assembly comprises a front wall inner plate assembly and a front wall outer plate assembly, wherein the front wall inner plate assembly and the front wall outer plate assembly are buckled together to form a double-layer composite structure, and a sealed cavity is formed in the double-layer composite structure, and is positioned in a front collision area of the front wall assembly. By adopting the technical scheme, the front wall assembly has the advantages that the front wall assembly of the single-layer structure in the prior art is changed into the front wall assembly with the double-layer composite structure, so the larger collapsing amount produced in a driving cab by the front wall assembly is avoided, and the injury to passengers is reduced; the self strength of the front wall assembly with the double-layer composite structure is improved, the transfer effect of the action force is good, the defect of transfer interruption when the action force is transferred in the lower-strength area is improved, and the anti-collision capability is improved. The invention also provides the heavy truck with the front wall assembly.
