The invention discloses a drive axle of engineering machinery and the engineering machinery. The drive axle of the engineering machinery comprises an axle housing, a half shaft and a differential mechanism assembly. The first end of the half shaft is configured to be connected with a hub. And the half shaft and the differential assembly are arranged in the axle housing. The differential mechanism assembly comprises a differential mechanism, a parking braking device and a traveling braking device. The differential is connected with the second end of the half shaft. The parking brake device is configured to apply a braking force to the differential. The service braking device is configured to apply braking force to the half shaft. The parking braking device is integrated in the differential assembly, compared with an existing parking braking scheme and an existing service braking scheme, the parking braking device cannot be polluted by the external environment, the risks of rusting corrosion and braking failure are reduced, torque needed by service braking is smaller, the size of the service braking device is smaller, the structure is simple and compact, and the braking performance is good.

    本申请公开了一种工程机械的驱动桥和工程机械。工程机械的驱动桥包括桥壳、半轴以及差速器总成。半轴的第一端被配置为与轮毂连接。半轴和差速器总成均设置在桥壳内。差速器总成包括差速器、驻车制动装置以及行车制动装置。差速器与半轴的第二端连接。驻车制动装置被配置为向差速器施加制动力。行车制动装置被配置为向半轴施加制动力。驻车制动装置集成在差速器总成内部,相较于现有的驻车制动方案和行车制动方案,其不会受到外界环境的污染,降低生锈腐蚀和制动失灵的风险,行车制动所需的力矩更小,行车制动装置的尺寸也更小,结构简单紧凑,且制动性能好。
