The present disclosure relates to a drive axle assembly capable of reducing drag torque by eliminating an inner bearing seal from a wheel bearing and capable of reducing generation of frictional noise at corrugations of a shroud. The drive axle assembly includes: a wheel bearing assembled with a wheel housing; an outer ring having an annular shape and including an outer diameter portion fixed to the outer wheel of the wheel bearing; a shroud including a large diameter portion formed at one end of the shroud and assembled together with an inner diameter portion of the outer ring; and a bearing sealing unit provided between a small diameter portion formed at the other end of the shroud and a drive shaft to restrict rotation of the shroud and prevent introduction of foreign matter.

    本公开涉及一种驱动桥组件,该驱动桥组件能够通过从轮轴承消除内轴承密封件来减小拖曳转矩并且能够减少在护罩的波纹处的摩擦噪声的产生。该驱动桥组件包括:轮轴承,所述轮轴承和轮壳体组装在一起;外圈,所述外圈具有环形形状并且包括固定到轮轴承的外轮的外径部分;护罩,所述护罩包括形成在所述护罩的一端处并且和所述外圈的内径部分组装在一起的大直径部分;以及轴承密封单元,所述轴承密封单元设置在形成于所述护罩的另一端处的小直径部分和驱动轴之间,以限制所述护罩的旋转并防止引入异物。
