PURPOSE: A coupled torsion beam axle suspension is provided to improve driving comfort in the bump of a wheel by changing the mounting point of a trailing arm through a drive motor according to the motion of a vehicle. CONSTITUTION: A coupled torsion beam axle suspension comprises a trailing arm(4) and a mounting bush unit(15). In the mounting bush unit, an outer race(25) is fixed to the leading end of the trailing arm. An inner race(27) is formed inside the outer race. A bush rubber(29) is attached on the inner circumference of the outer race and the outer circumference of the inner race. A rotary rod(31) passes through an inner race. The both ends of the rotary rod are supported by a bush bracket(23) of a vehicle body. A slot(24) is formed vertically to the bush bracket. A vertical moving unit(70) is connected to the both ends of the rotary rod. |
