The invention relates to the technical field of automobiles, and discloses a torsion bar spring adjusting arm assembly which comprises a torsion bar spring, a connecting assembly is arranged at the front end of the torsion bar spring, a mounting sleeve is rotationally connected to the rear end of the torsion bar spring, a buffer box is fixedly connected to the front end of the mounting sleeve, a shaft ring is arranged in the buffer box, and a spring is arranged in the shaft ring. The middle of the shaft ring is fixedly connected with a torsion rod spring through a connecting rod, the shaft ring is symmetrically sleeved with a set of buffering bent pipes, the buffering bent pipes are fixedly connected with a buffering box, pistons are slidably connected into the buffering bent pipes, and the two pistons are fixedly connected with the shaft ring. And the piston divides the interior of the buffer bent pipe into an upper air chamber and a lower air chamber. The service life of the torsion bar spring is prolonged by adding a buffer structure to the torsion bar spring, fatigue cracks are reduced, the vehicle comfort is improved, meanwhile, the design of combining spline teeth and concave hexagonal grooves is adopted, the machining cost and difficulty are reduced, the abrasion condition is improved, and assembling and torque transmission are facilitated.

    本申请涉及汽车技术领域,公开了一种扭杆弹簧调整臂总成,包括扭杆弹簧,所述扭杆弹簧的前端设置有衔接组件,所述扭杆弹簧的后端转动连接有安装套管,所述安装套管的前端固定连接有缓冲盒,所述缓冲盒的内部设置有轴环,所述轴环的中部通过连接杆与扭杆弹簧固定连接,所述轴环上对称套设有一组缓冲弯管,所述缓冲弯管与缓冲盒固定连接,所述缓冲弯管的内部均滑动连接有活塞,两个所述活塞均与轴环固定连接,所述活塞将缓冲弯管的内部分隔为上气腔室和下气腔室。通过给扭杆弹簧增加缓冲结构延长其寿命、减少疲劳裂纹、提升车辆舒适性,同时采用花键齿与凹六角槽结合的设计降低加工成本和难度、改善磨损情况、利于装配和扭矩传递。
