Stiffness adjustable transverse elastic stopper on anti-side-roll torsion bar and stiffness adjusting method

The invention provides a stiffness adjustable transverse elastic stopper on an anti-side-roll torsion bar. Supporting seat assemblies and the transverse elastic stoppers are mounted on a torsion bar assembly of the anti-side-roll torsion bar. The transverse elastic stoppers are located on one sides of the supporting seat assemblies correspondingly. Each transverse elastic stopper comprises a fastener and an elastomer. The fasteners are fixedly connected with the torsion bar assembly. The elastomers are arranged between the fasteners and the corresponding supporting seat assemblies. When the anti-side-roll torsion bar generates lateral displacement, the elastomers are squeezed by the fasteners and the supporting seat assemblies to generate deformation. The elastomers are prevented from further deforming through the fasteners and the torsion bar assembly, so that the stiffness of the elastomers increases nonlinearly. When the transverse elastic stoppers bear large squeeze force, the elastomers can be blocked by
