The invention discloses a heavy chuck type drive axle wheel end assembly, which comprises a brake disc assembly, a hub bearing unit, a disc brake assembly, a half shaft, a half shaft bolt, an axle housing assembly and a locking nut, wherein the brake disc assembly is installed on the hub bearing unit, is fixed through the half shaft bolt and is matched with the disc brake assembly, and the hub bearing unit is installed on the axle housing assembly and is fixed through the half shaft bolt. The hub and brake disc integrated structure is achieved, the function of bearing braking force of the brake disc is achieved, the function of bearing wheel edge loads of the hub is achieved, the hub is omitted for the disc type wheel end, and therefore the weight and the cost of the wheel end are reduced;the hub bearing unit does not need to be disassembled when the brake disc is replaced, good assembly of the hub bearing unit can be ensured, the service life is greatly prolonged, and the whole vehicle bearing and reliability requirements are met; the inner diameter of the second cavity is increased by about 10% compared with the inner diameter of a common brake disc, and the heat dissipation capacity of the brake disc is improved.

    本发明公开了一种重卡盘式驱动桥轮端总成,包括制动盘总成、轮毂轴承单元、盘式制动器总成、半轴、半轴螺栓、桥壳总成、锁紧螺母,所述制动盘总成安装在轮毂轴承单元上,通过半轴螺栓固定,并与盘式制动器总成相配合,所述轮毂轴承单元安装在桥壳总成上,通过半轴螺栓固定。本发明实现了轮毂与制动盘一体化集成结构,不仅有制动盘的承载制动力的功能,同时有轮毂的承载轮边载荷的功能,使得盘式轮端取消了轮毂,从而降低了轮端的重量和成本;更换制动盘不需要拆卸轮毂轴承单元,可确保轮毂轴承单元装配良好,大大提高使用寿命,满足整车承载及可靠性要求;第二腔体的内径较普通制动盘内径增大约10%,提高了制动盘的散热能力。
