Description
技术领域
本发明属于刹车片制造技术领域，具体是一种金属基复合材料汽车刹车片。
背景技术
刹车片在汽车的刹车系统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，对提高汽车刹车系统的稳定性很有帮助。
发明内容
本发明的目的就是针对目前现有的石棉刹车片和半金属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，提供一种金属基复合材料汽车刹车片。
