Description
技术领域
本发明属于刹车片制造技术领域,具体是一种纳米材料改性汽车刹车片。
背景技术
刹车片在汽车的刹车***中属于最关键的安全制动零件,刹车效果的好坏都是刹车片起决定性作用,刹车片一般由钢板、粘接隔热层和摩擦块构成,其中隔热层是由不传热的材料组成,目的是隔热。摩擦块由摩擦材料、粘合剂组成,刹车时被挤压在刹车盘或刹车鼓上产生摩擦,从而达到车辆减速刹车的目的。由于摩擦作用,摩擦块会逐渐被磨损,一般来讲成本越低的刹车片磨损得越快。摩擦材料使用完后要及时更换刹车片,否则钢板与刹车盘就会直接接触,最终会丧失刹车效果并损坏刹车盘,从而造成难以想象的后果。
现有的摩擦材料市场中,刹车片分为石棉刹车片和半金属刹车片。石棉刹车片中因为石棉具有致癌的危害,该类型的刹车片逐渐再被市场淘汰;而半金属刹车片因为其中含有金属物质,在制动时很容易对对偶产生损伤,存在较大的制动危害的同时也使其寿命较短。
因此,研发一种新型的刹车片,对其性能提升,对提高汽车刹车***的稳定性很有帮助。
发明内容
本发明的目的就是针对目前现有的刹车片面临被淘汰或性能不稳定,在制动时容易产生潜在的制动危害的问题,提供一种纳米材料改性汽车刹车片。
