Beschreibung
Zusammenfassung:	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
