Description

Technical field [0001] The invention relates to a front steering drive axle assembly. Background technique [0002] With the continuous advancement of national urbanization and infrastructure construction, the production and sales of construction machinery and agricultural machinery have been significantly promoted, especially the production and sales of large-tonnage backhoe loaders and large tractors. At the same time, the technical level and manufacturing technology of construction machinery, tractors and other agricultural machinery have made considerable progress, and models with four-wheel drive are becoming more and more common. At the same time, higher requirements are put forward for the quality requirements of the whole machine. [0003] The working environment of construction machinery and agricultural machinery is harsh, and there are high requirements for the reliability and passability of the whole machine. Four-wheel drive models have become a trend. [0004] The cu...
