The invention belongs to the technical field of vehicles, and discloses a transmission mechanism, a disc drive axle assembly and a vehicle. The transmission mechanism comprises a hub unit, a flange plate assembly and a brake disc; the hub unit is coaxially arranged outside the shaft head; the flange plate assembly is coaxially arranged outside the hub unit, a first spline part is arranged on the inner side of the flange plate assembly, the first spline part is connected to the peripheral side of the hub unit in a matched mode, and the hub reduction gear shell is detachably connected to the flange plate assembly; the brake disc is coaxially arranged outside the shaft head, the brake disc and the flange plate assembly are sequentially arranged in the length direction of the shaft head, the brake disc is detachably connected with the flange plate assembly, one part of the hub unit extends into the brake disc, and a second spline part is arranged on the inner side of the brake disc and connected to part of the hub unit in a matched mode. The second spline parts are connected to the first spline part side by side in the length direction of the shaft head. When the brake disc is disassembled, assembled and replaced, the hub unit does not need to be disassembled from the shaft head, and therefore the service life and the sealing performance of the hub unit are prevented from being affected.
本发明属于车辆技术领域,公开了一种传动机构、盘式驱动桥总成及车辆,该传动机构包括轮毂单元、法兰盘总成和制动盘;轮毂单元同轴设置于轴头外部;法兰盘总成同轴设置于轮毂单元外部,法兰盘总成内侧设置第一花键部,第一花键部配合连接于轮毂单元外周侧,轮边减速器壳可拆卸连接于法兰盘总成;制动盘同轴设置于轴头外部,沿轴头的长度方向与法兰盘总成依次设置,并与法兰盘总成可拆卸连接,轮毂单元的一部分伸入制动盘,制动盘内侧设置第二花键部,第二花键部配合连接于部分轮毂单元,第二花键部沿轴头的长度方向并排衔接于第一花键部。在拆装更换制动盘时,无需将轮毂单元从轴头上拆卸,进而避免影响轮毂单元的使用寿命和密封性能。
