一种用于盘式制动器的制动钳体上的钢盖帽结构
本技术涉及制动器
,特别涉及一种用于盘式制动器的制动钳体上的钢盖帽结构。
技术介绍
盘式制动器用于车辆上,实现车辆的刹车制动。盘式制动器的制动钳体与浮动支架之间通过导向销的导向进行来回滑动。在装配盘式制动器时,导向销需要涂抹润滑脂保证其滑动功能及其他零部件的寿命。盘式制动器总成在装配后,导向销外需安装钢盖帽。钢盖帽可以起到防尘防水的效果,避免制动器内部的金属件生锈,也可避免尘埃进入制动钳体的内部,从而防止出现系统运行阻塞的现象,进而避免导致制动失效或制动抱死。但是,现有的钢盖帽与制动钳体之间是过盈装配的结构。这种结构的装配,无法保证润滑脂能充分填满导向销处的装配间隙,而且在长时间的工作后,导向销处容易出现缺油现象,钢盖帽又很难拆卸,无法补充润滑脂,进而导致干摩擦现象,最终降低导向销的使用寿命。由于钢盖帽不易拆卸,后期维修更换也不方便。另外,现有的钢盖帽结构无法配合制动器的内部系统进行排气,因而也无法满足使用需求。
