The invention relates to an automobile rear shaft steering drive axle which comprises a rear shaft (2) provided with a shaft housing (1). The two ends of the rear shaft (2) and the two ends of the shaft housing (1) are connected with automobile hubs (3) respectively. The two ends of the axle shaft (2) and the two ends of the shaft shell (1) are cut off at a set distance from the hubs. The rear shafts (2) on the two sides of the cross section are connected through ball cage type universal joints (4) at the two cut-off positions respectively. Steering knuckle assemblies are arranged on the outersides of the shaft housing (1) between the universal joints and the hubs respectively. Each steering knuckle assembly comprises an upper steering knuckle (5) and a lower steering knuckle (6) which are coaxially arranged, the upper steering knuckles (5) and the lower steering knuckles (6) are movably installed on a frame, and the lower steering knuckles (6) are further connected to a steering gearthrough trapezoidal arms (7). Compared with the prior art, the automobile rear shaft steering drive axle is simple in structure and wide in applicability, a drive axle is easily transformed into a steering drive axle, and rear shaft steering is achieved.
