The invention discloses an independent suspension steering drive axle, which comprises a main reducer arranged on the drive axle and fixed on a vehicle frame; a wheel reductor arranged on a wheel; a transmission axle, one end of which is connected with the main reducer and the other end thereof is connected with the wheel reductor; a left swing arm and a right swing arm, one end of which is respectively connected to the casing body of the main reducer and the other end thereof is respectively connected with the wheel reductor; a steering linkage, both ends of which are connected with the wheel reductor; the independent suspension steering drive axle is characterized in that the both ends of the transmission axle are connected with the main reducer and the wheel reductor respectively through spherical hinges. By adopting the heavy duty vehicle of the independent suspension steering drive axle, the requirements of large rotating angle and high jumping volume of the wheel can be met through the hanging spherical hinges, and a spiral spring is installed on the lower swing arm to cause the mounting height of the spiral spring to be reduced; the wheel can normally run at constant speed at the equilibrium position under the conditions of jumping at large amplitude and rotating at large angle by using the double-ball-basket constant velocity universal transmission axle, and the requirement of performance of the Third Generation military vehicle is met.
