The invention relates to a drive axle assembly with a main speed reducer parking structure. The drive axle assembly comprises a drive axle shell, a half shaft connected with the output end of a differential mechanism in the drive axle shell, a half shaft sleeve arranged on the outer side of the half shaft in a sleeving mode, a hub installed on the half shaft sleeve, a service braking mechanism which is mounted on one side of the hub, and a parking braking mechanism which is mounted on a main speed reducer shell. According to the equipment, the service braking mechanism and the parking braking mechanism are separately arranged, the service braking mechanism on the wheel side is formed by combining a brake disc and calipers, and the overall structure is simple; the parking braking mechanism is designed on a flange for transmission of the main speed reducer, a drum brake is adopted, the diameter of the parking brake is small, the mechanical braking effect is reliable, the structure is simple, the parking function can be achieved through a single parking brake, and the development cost is reduced.

    本发明涉及一种带主减速器驻车结构的驱动桥总成,包括驱动桥壳体,与驱动桥壳体内差速器输出端连接的半轴,套设在半轴外侧的半轴套管,安装在半轴套管上的轮毂,安装在所述轮毂一侧的行车制动机构以及安装在主减速器壳上的驻车制动机构。该设备将行车制动机构和驻车制动机构分开设置,轮边的行车制动机构采用制动盘和卡钳组合,整体结构简单;驻车制动机构设计在主减速器传动的凸缘上,采用鼓式制动器,驻车制动器直径小,机械式制动效果可靠,结构简单,单个驻车制动器能实现驻车功能,降低了开发成本。
