The invention discloses a drive axle and a service brake assembly of the drive axle. The drive axle comprises a first shaft sleeve positioned in a second shell, an annular piston, a plurality of annular first outer friction plates and a plurality of annular first inner friction plates, and the first shaft sleeve is in transmission fit with an axle shaft through an inner spline; the plurality of annular first inner friction plates and first outer friction plates are alternately stacked, and the piston is installed on the second shell and can move between a braking position and a non-braking position; elastic check rings are further arranged, axial spline grooves and circumferential annular grooves are formed in the outer surface of the first shaft sleeve, a plurality of first mounting grooves are formed in the inner side wall of the second shell, and the first outer friction plates are clamped in the first mounting grooves; and the first inner friction plates are clamped in the spline grooves and then are in transmission connection with the first shaft sleeve, and the elastic check rings are clamped in the annular grooves and located between any two adjacent first inner friction plates. According to the technical scheme, axial positioning of the first shaft sleeve can be completed, and installation of the whole service brake assembly is facilitated.

    本发明公开了一种驱动桥及其行车制动总成,包括位于第二壳体内的第一轴套、环形的活塞、若干环形的第一外摩擦片和若干环形的第一内摩擦片,第一轴套通过内花键与半轴传动配合,多个环形的第一内摩擦片和第一外摩擦片彼此交替叠置,活塞安装在第二壳体上并可在制动位置和非制动位置之间移动;还设有弹性挡圈,第一轴套的外表面上设有轴向的花键槽以及周向的环形槽,第二壳体的内侧壁上设有若干第一安装槽,第一外摩擦片卡设在第一安装槽内;第一内摩擦片卡设在花键槽内进而与第一轴套传动连接,弹性挡圈卡设在环形槽内并位于任意相邻两个第一内摩擦片之间;通过本技术方案可完成第一轴套的轴向定位,并方便整个行车制动总成的安装。
