摩擦材料不合格的主要問題
瀏覽次數:3687 發布時間: 2018/4/5   【關閉窗口】
    據了解,汽車用制動器襯片產品摩擦系數、指定摩擦系數允許偏差是該產品標準中最重要的兩個指標,能直接反映出產品摩擦性能的優劣。產品的摩擦系數過高或過低都會直接影響到汽車制動效果,摩擦系數低會產生制動不靈敏甚至制動失效的嚴重后果,摩擦系數高會導致汽車制動后打滑甚至翻轉的嚴重后果。因此在各個溫度段都有穩定的摩擦系數是優質產品的重要表現。摩擦系數的適用范圍,100℃時,一般在0.25~0.65之間,溫度上升其適用范圍也隨之拓寬,上限升至0.70,下限也有所下降。
    指定摩擦系數的允許偏差是指各個溫度段測得的產品的摩擦系數與產品指定摩擦系數的差值,這個差值不能超過標準中規定的范圍。
