Vehicle for civil engineering, forestry or other work, including an articulated chassis made of two elementary chassis (1, 2) joined together by an articulation piece (3) leaving them two degrees of freedom, on the one hand about a vertical axis YY and, on the other hand, about a horizontal axis XX. The connection and articulation assembly (3) joining the two elementary chassis (1, 2) together consists of a single-piece U-shaped piece, one of the branches (4) of which is associated with the front chassis (1) about a vertical axis YY located in the longitudinal plane of symmetry of the vehicle and the other branch (5) of which is associated with the rear chassis (2) about a horizontal axis XX, this branch (5) exhibiting, on its lateral edges, on either side of the longitudinal plane of symmetry (P), two symmetric inclines (6, 7) against which the rods (8, 9) of two hydraulic cylinders (10, 11) having a common connection circuit bear, each cylinder being associated with a controlled valve located in the said connection circuit. <IMAGE>
