Abstract: A method and mount assembly comprising a screw mechanism including a sleeve rotatable relative to the first housing and defining an internal screw-thread for adjusting the stiffness in the mount assembly in a vehicle. A collar non-rotatably secured to the plate and extends axially into the sleeve and defines an external screw-thread engaging the internal screw-thread of the sleeve. The internal screw-thread and the external screw-thread are self-locking in a static condition and prevent relative rotation between the sleeve and the collar below a predetermined force therebetween. A fluid pressure in the first housing overcomes the predetermined force and causes the sleeve to rotate from the static condition for moving the collar and the plate axially to change the stiffness of the pad.

Abstract: A fluid damper assembly including a housing that defines a chamber. A rod extends into the chamber and is axially moveable relative to the housing. A bushing is disposed about the rod and is fixed relative to the housing for guiding the rod during the axial movement of the rod. A piston is connected to the rod and is disposed in axially sliding engagement with the housing in the chamber in a compression stroke and in a rebound stroke in response to relative movement between the rod and the housing. A cushioning device extends from the bushing and biases the piston toward the compression stroke for dampening movement of the piston during the rebound stroke of the piston. The cushioning device and the bushing are integral with one another and of a homogeneous material.

Abstract: A vibroisolating device (1) comprises a substantially elastomeric core (2) configured to be connected with a first displaceable object (3) and provide with an opening (21) configured to be connected with a second displaceable object (4). In order to obtain a nonlinear force vs. displacement characteristic of the device, substantially symmetrical around a certain and adjustable nonzero displacement value, the device (1) comprises at least one Belleville spring (5) disposed on the vibration transmitting path between said first displaceable object (3) and said second displaceable object (4), which is at least partially embedded in the volume of said substantially elastomeric core (2) and surrounds said opening (21). In particular the spring (5) is preloaded while said vibroisolating device (1) is in vibrations equilibrium position. The invention also relates to a motor vehicle suspension, in particular an adjustable active suspension system, comprising such a vibroisolating device.
