,具体涉及一种防水防垢ABS轮速传感器。
技术介绍
ABS防抱死制动系统是一种具有防滑、防锁死等优点的汽车安全控制系统。可安装在任何带液压刹车的汽车上。ABS防抱死制动系统的重要组成部件轮速传感器实时测量车轮的转速并通过电子信号传输至ABS电子控制单元,电子控制单元对这些信号进行分析并加以计算,控制车轮的滑移率,从而提高汽车制动时的安全可靠性。由于轮速传感器在使用时安装在汽车轮毂中,道路上的盐水等腐蚀性污水会通过轮速传感器进入到轮毂内,污染轮速传感器的探测头及齿圈。针对上述问题,中国专利CN201620679416.5公开了一种ABS轮速传感器的头部改良结构。将芯片预先装入塑料骨架,然后将塑料骨架放入套筒中再进行局部注塑封装,这样就可避免了高温、高压、高流速对芯片的直接伤害,提高了产品合格率;传感器颈部上注塑成型形成的塑料密封件,将传感器接插件组件与传感器颈部之间的接插缝隙密封,将套筒与传感器颈部之间的接插缝隙密封,大大提高了密封性能。但是该装置存在一问题就是,套筒外壁设置的卡槽及密封圈只能密 ...
