Abstract
A suspension for a vehicle includes a displacer which can be actuated by the relative motions between a vehicle wheel and the vehicle body. The displacer includes a working space or chamber containing a flow medium connected by at least one throttle to one of at least two springs which can be loaded by the flow medium. The two springs have different load-dependent spring rate changes whereby the distribution of the volume proportions of flow medium displaced to the springs differs depending on the static flow medium pressure. At least one throttle which operates as a function of load is placed in front of the less progressive spring.
Claims29
A suspension system for a vehicle comprising displacer means responsive to the relative motions between a vehicle wheel and the vehicle body, said displacer means including means for containing a flow medium, at least two spring means connected to said means for containing a flow medium which can be loaded by said flow medium, said at least two spring means being continuously responsive to flow of said flow medium, one of said at least two spring means being less progressive than the other of said at least two spring means, at least one throttle means for continuously controlling the movement of flow medium into said one of said at least two spring means, said at least two spring means having different load-dependent spring rate changes whereby the distribution of the volume proportions of flow medium displaced to each of the spring means differs depending on the static flow medium pressure and whereby said at least one throttle means is disposed in front of said less progressive spring means and operates as a function of load.
