An axle assembly for a driving wheel of a vehicle allows a wheel-side joint and a shaft to be rotated separately from a boot while driving so as to prevent generation of friction noise of the boot. The axle assembly includes the shaft rotated by receiving driving force from a powertrain; an axle housing disposed to pass through a center of a steering knuckle connected to a steering apparatus; a wheel bearing mounted between the steering knuckle and the axle housing; a joint bearing mounted on an outer part of the shaft; and a boot unit configured to have a first end coupled to an outer race of the joint bearing and a second end coupled to an outer race of the wheel bearing so as to form a space filled with a lubricant outside the shaft.
本公开提供一种用于车辆的驱动轮的轮轴组件,在行驶时使车轮侧万向节和轴与保护罩分开旋转,以从根本上防止保护罩的摩擦噪声的产生。该轮轴组件包括:轴,通过从动力系统接收驱动力而旋转;轮轴壳,被设置成穿过连接到转向设备的转向节的中心;车轮轴承,安装在转向节和轮轴壳之间;万向节轴承,安装在轴的外部;以及保护罩单元,保护罩单元的第一端联接到万向节轴承的外环,保护罩单元的第二端联接到车轮轴承的外环,以在轴的外部形成用于填充润滑剂的空间。
