An anti-side-rolling torsion bar assembly comprises a torsion bar shaft, a torsion arm fixed to the end of the torsion bar shaft and a supporting base assembly arranged on the torsion bar shaft in a sleeving mode, and is characterized by further comprising an anti-loosening assembly used for preventing the torsion arm from loosening on the torsion bar shaft and an anti-moving assembly used for preventing the supporting base assembly from moving relative to the torsion bar shaft. The anti-loosening assembly is installed on the torsion arm, and the anti-moving assembly is in axial positioning fit with the supporting base assembly and is fixed to the torsion arm. The torsion arm serves as a connecting piece of the anti-loosening assembly and the anti-moving assembly, the anti-moving assemblytransmits transverse moving force of the supporting base assembly to the torsion arm, the anti-loosening assembly ensures that the torsion arm is good in positioning stability and high in force bearing reliability, loosening of the torsion arm on the torsion bar shaft is prevented, and the supporting base assembly is prevented from axially moving relative to the torsion bar shaft, so that the anti-moving reliability is higher. The invention further provides an anti-moving method of the anti-side-rolling torsion bar assembly.
抗侧滚扭杆组件,包括扭杆轴、固定在扭杆轴端部的扭转臂、套装在扭杆轴上的支撑座组件,其特征在于:还包括用于防止扭转臂在扭杆轴上松动的防松动组件和防止支撑座组件相对于扭杆轴窜动的防窜动组件,所述的防松动组件装在扭转臂上,防窜动组件与支撑座组件轴向定位配合且与扭转臂固定。本发明中扭转臂做为防松动组件和防窜动组件的连接件,防窜动组件将支撑座组件的横向窜动力传递至扭转臂,而防松动组件保证了扭转臂的定位稳定性好、承力可靠性高,实现了即防止扭转臂在扭杆轴上的松动,又防止了支撑座组件相对于扭杆轴的轴向窜动,防窜动可靠性更高。本发明还提供一种抗侧滚扭杆组件的防窜方法。
