The invention discloses an HMT-driven time-sharing four-wheel drive axle, and belongs to the technical field of agricultural machinery. The defects that in the prior art, a traditional drive axle is driven by static hydraulic pressure, walking gear shifting cannot be achieved, and only parking gear shifting can be achieved are overcome. The main structure of the transmission comprises a transmission shell, an input shaft, an HMT power input shaft, a high-low gear transmission mechanism, a first front driving wheel output half shaft, a second front driving wheel output half shaft and a four-wheel drive transmission mechanism are arranged on the transmission shell, one end of the input shaft is connected with an HMT through a connecting sleeve, and the output end of the HMT is connected with the HMT power input shaft. A differential assembly is arranged on the first front driving wheel output half shaft and the second front driving wheel output half shaft, the HMT power input shaft is in transmission connection with the differential assembly through a gear shifting transmission mechanism, the differential assembly is in transmission connection with a four-wheel drive transmission mechanism, and the end of the first front driving wheel output half shaft and the end of the second front driving wheel output half shaft are connected with an axle tube and an edge reduction assembly. The invention is mainly applied to agricultural machinery.
