The invention discloses a hydraulic drive axle for a vehicle, which comprises semi-shafts, swing disc type axial plunger motors, shells and wheels, wherein the semi-shafts and the swing disc type axial plunger motors are installed in the shells; the swing disc type axial plunger motors are connected with the semi-shafts; and the wheels are installed on the semi-shafts. According to the invention, the swing disc type axial plunger motors are used for providing power for the wheels, and the current most common gear drive is replaced; compared with the gear drive, the hydraulic drive axle has the advantages that the structure is greatly simplified, stepless speed change in a large scale can be easily realized, the transfer movement is more smooth, the inertia of hydraulic motors is small, and quick and shockless speed change and direction change can be realized; the swing disc type axial plunger motors are used for replacing common hydraulic motors, and few parts are adopted; and under the conditions of high speed and high pressure, the operational reliability is higher and the service life is longer.
