At present, the mainstream configuration of the domestic loader industry generally uses dry drive axles, and the structure of the drive axles is also basically the same. Dry-type pliers-and-disc structure, the axle housing is an integral welded axle housing, etc. The main reduction gear transmission adopts Gleason spiral bevel gear with the advantages of large input torque, high transmission efficiency, and stable work; the wheel side reduction gear adopts planetary reduction transmission structure (NGW type), which has good overall rigidity and output Speed is smooth. Between the main reduction gear and the wheel-side reduction gear, a full floating half-shaft connection is used to transmit power. The axle shaft has a certain amount of floating in the axle housing, which overcomes the influence of the axle housing deformation on the axle shaft.
