An articulated vehicle made of a front and of a rear vehicle body of which the chassis are connected by an articulated joint. The articulated joint comprises a steering axis, a first longitudinal roll axis on the front chassis, and a second longitudinal roll axis on the rear chassis. In a structural sense, the articulated joint of the present invention comprises a first swivel member and a first shaft mounting this first swivel member on the front chassis for relative oscillation of the first swivel member and of the front chassis about the first longitudinal roll axis. Likewise, a second swivel member and a second shaft mounting this second swivel member on the rear chassis allow relative oscillation of the second swivel member and of the rear chassis about the second longitudinal roll axis. Spaced apart pivot pins are provided for pivotally joining the first and second swivel members together along the steering axis, and allowing pivotal movement of the front and rear chassis while a movement of the front chassis remains co-planar with a movement of the rear chassis. The articulated joint also comprises a first flexible torsion coupling connected between the first swivel member and the front chassis, and a second flexible torsion coupling connected between the second swivel member and the rear chassis for flexibly restraining the relative oscillation of the first and second swivel members and of the front and rear chassis about their respective longitudinal roll axes.
