The invention relates to the field of electric vehicle parts, and discloses a torsion beam for an electric vehicle, which comprises a cross beam, a hub bracket, a longitudinal arm, an anti-roll rod, a spring disc and a shock absorber bracket. Compared with the prior art, the invention has the following advantages and effects: as the cross beam adopts the stamping opening variable cross-section cross beam, is arranged at the end part of the trailing arm and close to the center of the wheel, has a backward opening and is different from the traditional torsion beam cross beam, space is reserved for mounting the battery in the X direction, and meanwhile, as the cross beam is close to the rear part, the torsion rigidity of the cross beam is relatively small, and the riding comfort is improved. The trailing arm is of a single-plate stamping structure, so that a space can be effectively reserved for the battery in the Y direction to facilitate installation, the weight of the assembly is reduced, and the cost is redu
