ASSISTED STEERING SET FOR A HYDRAULIC STEERING SYSTEM FOR MOTOR VEHICLES, ENERGIZED STEERING SET AND STEERING SUPPORT METHOD OF A HYDRAULIC MOTOR VEHICLE SYSTEM

摘要

power steering assembly for a motor vehicle power steering system, energized steering assembly and steering support method of a motor vehicle power steering system the present invention relates to an power steering assembly (20) for a hydraulic steering system for motor vehicles. the power steering assembly (20) comprises at least one hydraulic servo valve that has a control element (26) for controlling the steering support, depending on the rotation of an input shaft (22) with respect to an output shaft (28 ), at least two planetary gear trains (30, 40), each of which has three functional elements to transmit the rotational movement of the input shaft (22) or the output shaft (28) to the control element ( 26) and at least one driver (50) for rotating the control element (26) with respect to the input shaft (22) or the output shaft (28). the driver (50) is arranged and designed in such a way that the driver causes rotation in the same direction with simultaneous relative rotation of the two corresponding corresponding functional elements of the planetary gear trains (30, 40) with each other. the present invention also relates to a method comprising the steps of controlling the steering support depending on the rotation of an input shaft (22) with respect to an output shaft (28) by means of at least one hydraulic servo valve, transmission of rotational movement from the input shaft (22) or the output shaft (28) to the control element (26) by means of at least two planetary gear trains (30, 40) and rotation of the control element ( 26) with respect to the input shaft (22) or the output shaft (28) by means of at least one driver (50), in which, in order to rotate the control element relatively, the two third functional elements are rotated by the driver (50) in the same direction and at the same time.
