本发明公开了一种耐窜动且可多次拆装的车桥轮毂油封,包括外油封、轴套与限位骨架,所述限位骨架与轴套靠近右侧的位置铆合连接,所述外油封的顶部外表面胶连接有第一橡胶包覆层,所述第一橡胶包覆层位于轴套的上方,且第一橡胶包覆层的左侧底部设置有第一防尘唇,所述外油封远离第一橡胶包覆层的一端延伸至轴套的内侧并设置有主密封唇。本发明,通过第一防尘唇可防止大颗粒进入油封内部,第二防尘唇可防止泥水进入油封内部,第三防尘唇增加弹簧设计,增加防泥水效果,主密封唇可以封油防止泄漏,通过三个防尘唇可以保证油封在窜动下的防尘以及防泥水性,从而大大提高了油封的使用寿命。

    The invention discloses a displacement-resistant axle hub oil seal capable of being disassembled and assembled for multiple times. The oil seal comprises an outer oil seal, a shaft sleeve and a limiting framework; the limiting framework is riveted with the position, close to the right side, of the shaft sleeve; the outer surface of the top of the outer oil seal is connected with a first rubber coating layer in a glued mode, the first rubber coating layer is located on the shaft sleeve, a first dustproof lip is arranged at the bottom of the left side of the first rubber coating layer, and the end, away from the first rubber coating layer, of the outer oil seal extends to the inner side of the shaft sleeve and is provided with a main sealing lip. According to the invention, large particles can be prevented from entering the oil seal through the first dustproof lip; the second dustproof lip can prevent muddy water from entering the oil seal, the third dustproof lip is additionally provided with the spring design, the muddy water prevention effect is improved, the main sealing lip can seal oil and prevent leakage, dust prevention and muddy water prevention of the oil seal under displacement condition can be guaranteed through the three dustproof lips, and therefore the service life of the oil seal is greatly prolonged.
