Abstract

See full text

A hydraulic steering system for vehicles includes a steering control member; a hydraulic pump provided with a rotatable driving shaft on which the control member is fitted; a hydraulic actuating cylinder connected with two ports of the pump alternately operating as delivery side and return side of the pump and mechanically connected with a direction changing member, which determines a change in the direction by modifying orientation via an actuating cylinder as a function of the supply of hydraulic fluid to the cylinder from the pump by the steering control member. The driving shaft is dynamically connected with an electric motor/transmission assembly, which is activated alternatively by generating a rotational force auxiliary to the movement manually exerted on the steering control member or opposing the manually exerted movement, or by driving to rotate the driving shaft of the pump in place of the manual action driving the steering control member.
