Technical Problem
[0004]但是，上述技术方案存在如下不足之处：为了调节减震弹簧的预紧力，弹簧安装座通常与阻尼器螺纹连接，通过转动弹簧安装座改变弹簧安装座的位置实现减震弹簧预紧力的调节，弹簧安装座缺乏限位，减震器使用过程中，由于振动等外界因素会导致弹簧安装座发生位移，导致减震弹簧的预紧力发生变化；为实现减震弹簧预紧力的可调节性，弹簧安装座与阻尼器缸体通常采用螺纹连接配合，通过顺时针或逆时针转动弹簧安装座，可改变其在阻尼器缸体上的轴向位置，进而压缩或放松减震弹簧，达到调节预紧力的目的，然而，现有弹簧安装座未设计适配的限位固定结构，仅依赖螺纹连接的自锁性维持位置稳定
Benefits of technology
本实用新型通过连接套筒和调节套筒的螺纹配合结构，可精准改变弹簧安装座与安装托盘的间距，能根据车辆重量、行驶路况等场景，灵活适配不同刚度需求，通过限位齿轮、限位齿板和贴合弹簧构成的限位机构，实现调节后的刚性锁定，调节结束后，贴合弹簧会持续向限位齿板施加弹力，使其齿牙与调节套筒上的限位齿轮齿牙紧密啮合，直接限制调节套筒的转动。相比传统仅依赖螺纹自锁的结构，该设计能完全抵御路面颠簸、外部冲击等因素对调节套筒的周期性作用力，避免弹簧安装座位移，确保减震性能长期稳定。
