The invention discloses a torsion beam semi-independent suspension structure, particularly relates to the torsion beam semi-independent suspension structure for a car suspension system, and provides the torsion beam semi-independent suspension structure which can increase the roll stiffness of a torsion beam to guarantee that a vehicle has good operation stability under the working condition of turning. The torsion beam semi-independent suspension structure comprises two longitudinal arms, one torsion beam and a torsion bar, wherein the two longitudinal arms are connected to the two ends of the torsion beam; each longitudinal arm is provided with a rear shaft body bracket, a shock absorber support, a spring seat and a tire bracket; the rear shaft body bracket is arranged at the upper ends of the longitudinal arms; the shock absorber support is arranged at the lower ends of the longitudinal arms; the tire bracket is arranged on the sides, away from the torsion beam, of the longitudinal arms; the torsion bar is additionally arranged on the lower side of the torsion bar torsion beam. The roll stiffness and the rolling angle stiffness of the suspension can be increased under the condition that the stiffness of the suspension is not increased, so that the integral performance of the suspension is improved.
