一种带降噪垫渐变汽车板簧
本技术涉及汽车减震
,特别涉及一种带降噪垫渐变汽车板簧。
技术介绍
汽车板簧是汽车悬架系统中最传统的弹性元件,汽车工业使用板簧用于车体减震,汽车板簧的主要构件为主簧、下副簧、限位卡箍,中心螺栓和限位卡箍将主簧、下副簧连接为一整体,主簧、下副簧的长度呈阶梯状递减,最上层的主簧片长度最长,其两端弯折出主簧卷耳,主簧卷耳用于将汽车板簧定位安装于车体下方,当汽车板簧受力时,利用汽车板簧自身的弹力,达到缓冲压力的作用,当汽车板簧承重压力发生变化时,主簧、下副簧之间,主簧及限位卡箍之间易产生摩擦及异响,降低汽车行驶的舒适性及汽车板簧使用寿命。
技术实现思路
本技术的目的是为了解决上述技术的不足,提供一种结构简单,减少汽车板簧摩擦及异响的一种带橡胶圈渐变汽车板簧。为此,本技术提供一种带降噪垫渐变汽车板簧,其包括主簧、下副簧、限位卡箍,主簧、下副簧通过中心螺栓固定连接,主簧为两端向上的弧形结构,主簧两端设有主簧卷耳,下副簧的两端均连接设有降噪垫,下副簧的其中一端还连接设有限位卡箍,限位卡箍为厚8mm的U形板,主簧、下副簧、降噪垫均设于限位卡箍内,降噪垫设于主簧与下副簧之间,限位卡箍的底板通过铆钉依次与下副簧、降噪垫固定连接,限位卡箍的侧板内壁设有第一硫化橡胶层。优选的,降噪垫设有支撑部和缓冲部,缓冲部设于支撑部的上侧,支撑部为圆柱形,缓冲部为圆台形,降噪垫设有贯通的通孔,通孔包括安装孔和缓冲孔,安装孔孔径小于缓冲孔孔径。优选的,主簧包括三根等宽度弧形簧片,主 ...
