FIELD: motor vehicle industry.
SUBSTANCE: invention relates to a vehicle torsion beam suspension. Torsion beam suspension comprises a first member with an opening having U-shaped cross-section, a second member, a right and left longitudinal arm, and U-shaped torsion beam that is arranged between a pair of component members. When the torsion beam is twisted, the rigidity adjustment portions adjust the rigidity from the longitudinal arms to the torsion beam and are arranged such that the positions of the said portions are offset from each other. One of the rigidity adjustment portions comprises a connecting member for connecting to the beam, connected to the torsion beam in the second member. Connecting member for connecting to the beam comprises two or more extension parts. Extension parts are located on both sides of the axis of the torsion beam and have different lengths.
EFFECT: preventing sudden change in rigidity in the connecting part between the longitudinal arm and the torsion beam.
