A coupled torsion beam axle suspension of an automobile is provided to improve bending and torsion rigidity without increasing a section of the trailing arms by absorbing and dispersing applied force through a bush pipe installed in the middle of a torsion beam. A coupled torsion beam axle suspension of an automobile comprises a pair of trailing arms(200), a torsion beam(100), a spring sheet(300) and a spindle bracket(400). The trailing arms are disposed in both right and left sides of an automobile body. The torsion beam has one side and the other side end melt-bonded to the trailing arms. The spring sheet has a rear portion contacted and melt-boned between the torsion beam and the trailing arms. The spindle bracket has a lower portion melt-bonded in one side of an upper portion of the trailing arms. |
