Integral servo steering gear with rack transmission

摘要

Hydraulic servo steering gear having a cylindrical, double-acting working piston connected to a steering shaft by a rack-and-sector gear connection, especially for motor vehicles comprises a piston-and-sleeve type control mechanism arranged in the working piston. The cylindrical outer surface of the sleeve of the control mechanism is fitted loosely, with a radial gap, in the seat formed therefor in the double-acting working piston. The control sleeve is secured against axial and angular displacement.
