A transverse torsion bar spring for a motor vehicle suspension comprises a torsion bar extending transversely, the middle position of the torsion bar is fixedly connected with a middle rocker arm assembly in the circumferential direction, the two ends of the torsion bar are fixedly connected with side rocker arm assemblies in the circumferential direction respectively, and the transverse torsion bar spring of an E-shaped structure for axially positioning the torsion bar is formed. The middle rocker arm assembly comprises a middle rocker arm and a middle adjusting rod, one end of the middle rocker arm is circumferentially and fixedly connected to the middle of the torsion bar, the other end of the middle rocker arm is fixedly connected to the upper end of the middle adjusting rod, the lower end of the middle adjusting rod extends into a longitudinal strip-shaped hole formed in the frame cross beam or the auxiliary frame cross beam, and the middle adjusting rod is prevented from retreating from the strip-shaped hole through a limiting device. The side rocker arm assembly comprises a side rocker arm and a side adjusting rod, one ends of the left rocker arm and the right rocker arm are circumferentially fixed to the two ends of the torsion rod respectively, the other ends of the left rocker arm and the right rocker arm are movably connected with the upper ends of the left adjusting rod and the right adjusting rod respectively through ball joints, and the lower ends of the left adjusting rod and the right adjusting rod are fixedly connected with the left lower swing arm and the right lower swing arm or the left shock absorber cylinder and the right shock absorber cylinder respectively.
