产品介绍

橡胶减震器之所以如此被广泛的运用,是因为它有效的利用了橡胶的如下诸多特性:

(1)橡胶具有高弹性和黏弹性;

(2)与钢铁材质相比,橡胶的弹性变形很大,弹性模量很小;

(3)橡胶的冲击刚度大于动刚度,动刚度又大于静刚度,有利于减少冲击变形和动态变形;

(4)应力-应变曲线为椭圆形滞后线,其面积等于各个震动周期转变为热量的振能(阻尼),可通过配方设计调整之;

(5)橡胶为不可压缩性材料(泊松比为0.5);

(6)橡胶形状可以自由选择,硬度可以通过配方设计加以调整,可以满足不同方向的刚度和强度的要求。

突出优势

载荷范围

载荷范围:245N-35040N;位移范围有二种:0-75mm、0-150mm;

结构

结构采用外挑管,消除音隙非常方便,且有螺纹防松设置;

连接管

长短连接管采用左右螺纹,安装距离詷量为40mm,且可现场调整,并设有螺纹防松设置;

间隙小

两端接口采用铰接,有效地消除了双向使用时的间隙;

载荷刻度

上刻度板上增设了载荷指示刻度,使调节载荷、工作载荷一目了然。

产品作用

为了减少前面提到的路面对车辆的振动和冲击,需要弹簧把这些吸收振动和冲击的能量,弹簧在悬架中就是一个储能元件,但是暂时储存起来还不行,还要把这些对车辆乘坐舒适性和操纵稳定性不利的能量消耗掉,这是就轮到减振器登场了,液压式减振器的工作原理是当车架与车桥作往复相对运动,而活塞在缸筒内往复运动时,减振器壳体内的油液便反复地从一个内腔通过一些窄小的孔隙流入另一内腔,此时,孔壁与油液间的摩擦及液体分子内摩擦便形成对振动的阻尼力,使车身和车架的振动能量转化为热能,而被油液和减振器壳体所吸收,然后散到大气中。简单的说就是,将动能转化为热能。如果减振器在试验台连续运转几分钟,减振器贮油缸外壁会变得非常热,甚至烫手。
