INDEPENDENT STEERING HYDRAULIC DRIVE Russian patent published in 1996 - IPC

Abstract SU 1128493 A1

FIELD: mechanical engineering; follow-up hydraulic drives. SUBSTANCE: independent steering hydraulic drive has drive electric motor and spool-type distributor operated by electromechanical converter and hydraulic motor, tank and pump with valve-and-slot distribution, all intercoupled by delivery and return hydraulic lines. Mounted in pump housing are plungers and capacity regulator in form of spring-loaded differential rod rigidly coupled with bushings installed on plungers for sliding. To increase service life of hydraulic drive by decreasing starting load of electric motor, spring of pump capacity regulator is installed, without preloading, between rod and floating piston installed in housing. Non-spring loaded end of piston communicates with pump delivery hydraulic line. EFFECT: increased service life of steering hydraulic drive.
