ABSTRACT:
Stabilizer device for motor vehicles including a torsion bar, an actuator having a piston and two cylinder chambers on both sides of piston, a first and a second fluid passages for connecting said two cylinder chambers, respectively, a solenoid changeover valve provided in first fluid passage. A actuator has two openings for communicating with each end of first fluid passage within an area on which piston may not slidably contact. A plate member and a centering spring are provided within each of cylinder chambers in such a manner that each of plate members is to come in contact with a bottom surface of cylinder slightly by virtue of resilience of centering spring when piston is positioned in a neutral position. An opening is provided in each of bottom surface of cylinder chambers within an area on which plate member is to come in contact therewith. Each of openings is communicated with second fluid passage and a check valve may be mounted in each of openings.
Relative movement of torsion bar with a body portion of the vehicle resulted from up-and-down motion of wheels is transmitted to piston through a piston rod. During changeover valve allows flow of fluid flowing first fluid passage between cylinder chambers, anti-roll, anti-dive and anti-squat effects of torsion bar are made ineffective. When changeover valve prohibits flow of fluid in first fluid passage, fluid is trapped in both cylinder chambers, therefore, anti-roll or anti-dive and anti-squat effects of torsion bar are made effective. Fluid is allowed to flow from one cylinder chamber to another cylinder chamber through second fluid passage, then finally piston is positioned at neutral position.
