STEERING VALVE WITH PLANETARY GEAR

摘要

FIELD: transport.SUBSTANCE: set of inventions relates to automotive industry. Hydraulic servocontrol system unit for vehicles contains hydraulic servovalve with actuating element, two planetary gears and actuator. The first functional element of one planetary gear is connected without possibility to rotate with input shaft or output shaft. The first functional element of the other planetary gear is connected without possibility to rotate with actuating element. The second functional element connects planetary gears. The actuator is located and made so that it provides possibility of rotation in one direction with simultaneous relative rotation of both planetary gear functional elements relative to each other. Method of steering support of hydraulic servocontrol system for vehicles includes steps in which: - steering support is controlled depending on relative rotation of input shaft in relation to output shat by means of hydraulic servovalve; - rotary movement of input shaft or output shaft is transferred to actuating element by means of two planetary gears; - relative movement of actuating element in relation to input shaft or output shaft is performed by means of actuator to influence on steering support characteristic.EFFECT: decreased play of actuating element movement.13 cl, 4 dwg
