文章设计了一种刹车片厚度探测装置,阐述了其设计原理、装置制作方法及使用条件。本装置结构简单,易实现小型化,节能省电,便于安装,可用于对刹车片厚度范围的探测,增强汽车自主安全性。目前国内外汽车上还没有该项功能,因此具有比较广阔的推广应用前景。 The paper designed a brake pad thickness detection device, described its design principles, device manufacturing methods and conditions of use. The utility model has the advantages of simple structure, easy miniaturization, energy saving and electricity saving, convenient installation, detection of thickness range of brake pads and enhancement of autonomy of automobile. At present, this feature is not available on cars at home and abroad, so it has a broad prospect of popularization and application.
