產品介紹
橡膠減震器之所以如此被廣泛的運用,是因為它有效的利用了橡膠的如下諸多特性:
(1)橡膠具有高彈性和黏彈性;
(2)與鋼鐵材質相比,橡膠的彈性變形很大,彈性模量很??;
(3)橡膠的沖擊剛度大于動剛度,動剛度又大于靜剛度,有利于減少沖擊變形和動態變形;
(4)應力-應變曲線為橢圓形滯后線,其面積等于各個震動周期轉變為熱量的振能(阻尼),可通過配方設計調整之;
(5)橡膠為不可壓縮性材料(泊松比為0.5);
(6)橡膠形狀可以自由選擇,硬度可以通過配方設計加以調整,可以滿足不同方向的剛度和強度的要求。

產品作用
為了減少前面提到的路面對車輛的振動和沖擊,需要彈簧把這些吸收振動和沖擊的能量,彈簧在懸架中就是一個儲能元件,但是暫時儲存起來還不行,還要把這些對車輛乘坐舒適性和操縱穩定性不利的能量消耗掉,這是就輪到減振器登場了,液壓式減振器的工作原理是當車架與車橋作往復相對運動,而活塞在缸筒內往復運動時,減振器殼體內的油液便反復地從一個內腔通過一些窄小的孔隙流入另一內腔,此時,孔壁與油液間的摩擦及液體分子內摩擦便形成對振動的阻尼力,使車身和車架的振動能量轉化為熱能,而被油液和減振器殼體所吸收,然后散到大氣中。簡單的說就是,將動能轉化為熱能。如果減振器在試驗臺連續運轉幾分鐘,減振器貯油缸外壁會變得非常熱,甚至燙手。
