ABSTRACT:
There is provided a torsion beam of a vehicle suspension in which a upper portion and the lower portion of the torsion beam are bent in the front-to-rear direction alone of the vehicle along the longitudinal axis of the torsion beam, and a pair of tails is rounded at both front and rear ends of the torsion beam of the vehicle and formed different from each other in size, a rear tail of the pair of tails which is formed at the rear portion of the vehicle is larger than a front tail formed in the front portion of the torsion beam, the upper and lower portions of the torsion beam are gradually apart from each other with at least two predetermined slopes as they goes from the middle portion to both distal end of the torsion beam. Therefore, roll stiffness is increased and durability is improved.
