A four-wheel drive hydraulic mechanical continuously variable speed transmission device with a steering axle comprises an input shaft, a hydraulic continuously variable speed transmission, a shaft I, a shaft II, a shaft III, a shaft IV, a steering shaft, a shaft VI, a left driving shaft, a right driving shaft, a four-wheel drive transmission shaft and a bevel gear shaft. Power of a diesel engine is transmitted to the input shaft and the hydraulic continuously variable speed transmission through belt driving in sequence, transmitted to the shaft I through continuously variable speed and transmitted to the shaft II through gear engagement; the combination between the shaft II and the shaft III forms three-gear advancing speed change, then on the one hand, the power is transmitted to the driving shaft, a speed reducing main drive cross shaft and a steering axle speed reducing driven shaft to drive front driving wheels to run, and on the other hand, the power is transmitted to the bevel gear shaft to drive back driving wheels to run. According to the device, differential hydraulic steering and continuously speed change are achieved, and four-wheel drive transmission of the front driving wheels and the back driving wheels is achieved; meanwhile, left turning or right turning of the front driving wheels is achieved through a double-piston-rod oil cylinder which passes a left steering axle shell and a right steering axle at the same time.
