The invention provides a rear suspension structure for optimizing a whole vehicle rear suspension parameter adjusting tool space. The rear suspension structure comprises a rear auxiliary frame, a tail protruding eccentric bolt component, an adjusting eccentric bolt, a rear toe-in swing arm and a rear suspension rear lower swing arm. The rear auxiliary frame is fixedly connected with the rear toe-in swing arm through a tail protruding eccentric bolt component, and the rear suspension rear lower swing arm is fixedly connected with the rear auxiliary frame through an adjusting eccentric bolt. The tail protrusion eccentric bolt component comprises a bolt protrusion, a fixing nut and an eccentric gasket, the bolt protrusion penetrates through the eccentric gasket and the fixing nut, a cylindrical protrusion is arranged on the side, close to the fixing nut, of the bolt protrusion, and a cylinder structure is arranged at the tail of the cylindrical protrusion. The thickness of the column body part is gradually reduced in the direction away from the fixing nut. According to the invention, the visuality is good when the parameters of the rear overhang are actually adjusted, the rear overhang is basically not blocked, and enough tool space is ensured.

    本发明提供了一种优化整车后悬参数调整工具空间的后悬结构,包含后副车架、尾突偏心螺栓部件、调整偏心螺栓、后前束摆臂以及后悬后下摆臂;后副车架与后前束摆臂通过尾突偏心螺栓部件连接固定,后悬后下摆臂与后副车架通过调整偏心螺栓连接固定;所述尾突偏心螺栓部件包含螺栓突起、固定螺母、偏心垫片,所述螺栓突起穿过所述偏心垫片与所述固定螺母,且靠近固定螺母一侧有圆柱形突出,所述圆柱形突出的尾部设置有柱体结构,且柱体部分的粗度向远离所述固定螺母的方向逐渐收细。本发明可以使得在实际调整后悬参数时可视性良好、基本无遮挡,且保证有足够的工具空间。
