The invention provides a direct-connected four-wheel driven variable speed drive device with a steering axle. The direct-connected four-wheel driven variable speed drive device comprises an input shaft, a first shaft, a second shaft, a third shaft, a fourth shaft, a steering shaft, a sixth shaft, a left driving shaft, a right driving shaft, a four-wheel driven driving shaft and a rear output shaft. A high and low-gear duplicate gear on the first shaft and a third-gear variable speed duplicate gear on the third shaft are driven to be meshed with a third-gear variable speed gear and other gears so as to form four-gear speed variation; then, on one hand, power is transmitted to the driving shafts, a deceleration main drive cross axle and a steering axle deceleration driven shaft via the fourth shaft, the steering shaft and the sixth shaft; on the other hand, the power is transmitted to the rear output shaft via the fourth shaft and the four-wheel driven driving shaft; the rear output shaft is connected with a rear driving axle through a universal connecting shaft to drive rear driving wheels to run. By the device, power is divided into two ways for driving, and four-wheel drive of front driving wheels and the rear driving wheels is realized; meanwhile, left turning and right turning of the front driving wheels are realized through a double rod cylinder.
