摘要： 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.

摘要： The invention relates to a FRP leaf spring suspension for an automobile including a FRP leaf spring body interposed between a hat-shaped retainer having flanges at its free ends and a U bolt seat having opposed flanges through a rubber pad at its longitudinally central portion. The FRP leaf spring body is fixed through a spring seat to an axle housing by a U bolt passing through mating holes formed in flanges of the retainer and the U bolt seat. A reinforcing fiber impregnated with resin is wound around a central portion of the FRP leaf spring body and is fixed thereto to form unevenness on a surface of the FRP leaf spring body, thereby distributing frictional force between the FRP leaf spring body and the rubber pad uniformly on the frictional contact surface of the FRP leaf spring body, and preventing stress concentration from being generated in the FRP leaf spring body. In another mode, there are formed each unevenness on an upper and a lower surface of the central portion of the FRP leaf spring body, a lower surface of the retainer, and an upper surface of the U bolt seat, thereby preventing stress concentration from being generated in the FRP leaf spring body.
