The invention discloses a novel anti-rolling torsion-bar system. The novel anti-rolling torsion-bar system is characterized by comprising a torsion bar and a spherical hinge support, wherein a friction sleeve is connected to the internal surface of the spherical hinge support in an interference fit manner, the friction sleeve sleeves the torsion bar in a clearance fit manner, a limit block which limits the transverse movement of the friction sleeve is arranged on the torsion bar, the friction sleeve extends out of the spherical hinge support, the length, extending out of the end surface of the spherical hinge support, of the friction sleeve is larger than the accumulated tolerance of the novel anti-rolling torsion-bar system mounted between a vehicle body and a frame, and the interference force between the friction sleeve and the spherical hinge support is greater than the transverse movement force of the spherical hinge support when a vehicle runs. The novel anti-rolling torsion-bar system provided by the invention is wide in application range; when the novel anti-rolling torsion-bar system is mounted between the vehicle body and the frame, the transverse positioning is accurate, and the manufacturing cost of the vehicle does not need to be increased. The invention further provides a positioning and mounting method of the novel anti-rolling torsion-bar system.
