Abstract:
A hydraulically supported steering system with a steering gear, wherein the steering gear is driven by a hydraulic cylinder unit, the steering system comprising:a piston, axially displaced in a cylinder, wherein the piston substantially separates the cylinder into at least two cylinder section; at least one hydraulic line connected to at least one cylinder section, wherein the at least one hydraulic line is adapted to serve as at least one of the following: a pressure supply line and a pressure return line; a servo valve connected to the at least one hydraulic line; and a throttle mechanism disposed in the at least one hydraulic line, wherein the throttle mechanism is a self-regulating throttle mechanism having a variable flow resistance, in at least two variable resistance direction, such that a flow of a hydraulic fluid through the throttle mechanism in at least two direction determines the resistance in the at least two direction.
