A coupled torsion beam axle suspension structure is provided to remarkably increase lateral rigidity and torsional rigidity of a coupled torsion beam axle without increasing the thickness of a torsion beam or the diameter of a torsion bar. A coupled torsion beam axle suspension structure includes a torsion beam(3) and a reinforcement beam(5). A trailing arm(1) is combined with both ends of the torsion beam. The torsion beam has a V-shaped section and a triangle formed by the V-shape section is empty. The reinforcement beam has a V-shaped section is combined with the torsion beam outside the triangle. The length of one side of the V-shaped section of the reinforcement beam is greater than half the length of one side of the V-shaped section of the torsion beam. |
