Abstract

Improvements in the Patent of Invention No. 298.633 by "Servo-direction with regulation of mechanical participation", specifically one of the type in which, before the action of the hydraulic part, must be overcome, by turning the steering wheel, an initial mechanical effort that opposes to said turn, and in which means are provided to regulate the intensity of the initial effort according to the needs of the moment and at any moment of the vehicle's march, whose means act on a spring, which determines said initial effort, in order to vary by compression or decompression of the spring the intensity of the initial stress in question, characterized in that the device of regulation of the initial force consists of two annular pieces arranged around the tubular stem and related to each other by teeth in inclined plane located in their opposing transverse faces, one of whose parts has an external axial groove in which is lodged a fia a solidary body to the tubular body of the power steering, in order to prevent the rotation of the piece and allow its longitudinal sliding, while the other piece has a peripheral toothing that meshes with the drive pinion, so that the rotation of the latter takes place annular piece through said pinion, the movement is transformed into an axial displacement of the first of said pieces, through the inclined planes of its teeth, whose movement tends to compress or release the main spring, according to the sense of that, in order to vary the initial tension of the same spring.
