2. An elastic stop positioning structure is added between the support seat assembly and a torsion arm in the torsion bar assembly.
3. The positioning is carried out by the lap joint of the supporting spherical hinge in the supporting seat and the arc of the integral bending torsion bar.
In summary, in order to limit the relative movement between the torsion bar assembly and the support seat assembly and prevent the torsion bar assembly from moving relative to the support seat assembly along the transverse direction, a limit structure is additionally arranged between the torsion bar shaft and the support seat assembly, the limit structure has overlarge bearing force and is easy to deform, and the anti-moving reliability of the limit structure is still to be improved.
