The invention relates to a torsion beam rear suspension structure with an auxiliary frame, and relates to the technical field of automobile design and manufacturing. The torsion beam rear suspension structure with the auxiliary frame comprises a torsion beam, the frame-shaped auxiliary frame, a damper spring and a damper, an auxiliary frame structure is introduced on the basis of a traditional torsion beam suspension structure, and rubber bushings are installed at the four corners of the auxiliary frame in a pressing mode. A rear suspension Kamp can be optimized by adjusting the span in the front-back direction of the auxiliary frame and the rigidity of a front rubber bushing and a rear rubber bushing while secondary vibration reduction is added; c, the control stability and the riding comfort of the whole vehicle are improved; due to the fact that the torsion beam is installed on the rear auxiliary frame, a certain adjusting gap can be reserved between inner sleeves of bushings at the four corners of the rear auxiliary frame and installation bolts, an adjusting space is provided for the out-of-tolerance of the toe-in angle of a rear wheel, and the off-line qualification rate of the whole vehicle is increased.
本发明涉及一种带副车架扭力梁后悬架结构,涉及汽车设计和制造的技术领域。本发明的带副车架扭力梁后悬架结构,包括扭力梁、框型副车架、减振弹簧和减振器,该结构在传统扭力梁悬架结构基础上引入副车架结构,副车架四角压装有橡胶衬套,增加二级减振同时可通过调整副车架前后方向跨距及前后橡胶衬套刚度优化后悬架K&C特性,提高整车操纵稳定性及乘坐舒适性;扭力梁因安装在后副车架上,后副车架四角衬套内套管可与安装螺栓预留一定调整间隙,为后轮前束角超差提供调整空间,增加整车下线合格率。
