The invention relates to a hydraulic circulating ball type power steering gear of an automobile. The hydraulic circulating ball type power steering gear comprises a shell. A control valve assembly, a rack piston assembly and a rocker arm shaft assembly are arranged in the shell, the rack piston assembly comprises a screw, a plurality of steel balls and a nut with a rack, an oil plug is fixedly connected to the top of the rack piston assembly, the steel balls are arranged in a closed circulating pipeline between a piston and the screw, the rocker arm shaft assembly comprises a rocker arm shaft and sector teeth, the sector teeth and the rocker arm shaft are integrated with one another, and the sector teeth of the rocker arm shaft are meshed with the rack on the piston. The hydraulic circulating ball type power steering gear is characterized in that an adjustable rack piston stroke limiting device is arranged at a shell end cover at the other end of the hydraulic circulating ball type power steering gear, is opposite to the control valve assembly and comprises a nut and an adjusting screw, the nut is mounted at the end cover via a sealing component, and the adjusting screw is matched with the nut. The hydraulic circulating ball type power steering gear has the advantages that the maximum axial moving stroke of the rack and the piston can be differently constrained, accordingly, steering swing angles can be adjusted, and the hydraulic circulating ball type power steering gear is simple in structure and convenient to adjust.
