The Doser pump (hydraulic steering) is designed to supply liquids to the executive hydraulic cylinders in proportion to the angle of rotation of the output shaft. The main elements of the power steering are as follows: a planetary gearbox, a distributor and a feedback hydraulic motor. The power steering distributor consists of a housing in which the spool, sleeve and shaft are located. The shaft is fixed with the help of a thrust bearing and a cover. The sleeve is fixed in the spool and rotates relative to the spool or moves along with the spool in the axial direction. The power steering reducer consists of a satellite, a bearing and awheel. The hydraulic motor consists of a body, covers, gears, a roller with a finger, as well as axes that are installed in bearings. All hydromotor mechanisms are fixed with pins.
