Abstract: A suspension fluid prepared by dispersing polyethylene oxide particles into a solvent including water and one or more types of compounds selected from the group consisting of ethylene glycol and propylene glycol, and a method for manufacturing the same. The phase-change suspension fluid can be a shear-thinning fluid showing a constant newtonian behavior in a low shear rate or low frequency region, but showing a non-newtonian behavior appearing as liquid-like suspension in a high shear rate or high frequency region due to viscosity decrease, and is capable of reversible phase changes by the vibration of a vehicle, and therefore, may provide effects of having advantages of a hydraulic bush in a low frequency region and also having advantages of a solid bush in a high frequency region.

Abstract: A fluid-filled cylindrical vibration-damping device including a main rubber elastic body elastically connecting an inner shaft member and an outer cylindrical member with each other. A pair of first fluid chambers are formed on diametrically opposite sides of the inner shaft member and a pair of second fluid chambers are formed being diametrically opposed to each other such that an opposing direction of the second fluid chambers is orthogonal to an opposing direction of the first fluid chambers. Each partition wall that partitions the first fluid chamber and the second fluid chamber extends in a direction in more proximity to the opposing direction of the first fluid chambers than to the opposing direction of the second fluid chambers so that spring rigidity as measured in the opposing direction of the first fluid chambers is set greater than spring rigidity as measured in the opposing direction of the second fluid chambers.

Abstract: The invention relates to a hydroelastic joint that is used to assemble two pieces. The inventive joint comprises an external reinforcement (1) and an internal reinforcement (3), each having a longitudinal axis, and one of which is disposed around the other. Moreover, said joint comprises a first assembly (5) forming a hydroelasctic spring which is disposed between said reinforcements. The aforementioned first assembly comprises a first elastically-deformable element (6) which is shaped in such a way as to define, between the reinforcements, at least one sealed volume (9) that contains a damping fluid (8). A second elastically-deformable element (24) is disposed between the first assembly and the first of said external and internal reinforcements. The invention is characterised in that the second elastically-deformable element (24) is provided with a longitudinal dimension which is smaller than the corresponding longitudinal dimension of the first elastically-deformable element (6). In this way, the transversal deformation of the first elastically-deformable element (6) is limited during the relative tilting of the longitudinal axes of said reinforcements around at least one transverse tilting axis (D).

Abstract: A hydraulic bushing forms a mount between a first component and a second component by including a first spring portion connected between a core and an inner support structure and a second spring portion surrounding the inner support structure. The first spring portion is formed of rubber and defines hydraulic fluid cavities and a fluid channel extending between the cavities, while the second spring portion is formed of microcellular polyurethane. The first spring portion and the second spring portion are located so they operate in series with one another. In this way, vibrations of a load transferred through the hydraulic bushing can be damped at a predetermined low frequency by the rubber with hydraulic fluid cavities, while still allowing for isolating of higher frequencies by the microcellular polyurethane.

Abstract: A liquid-sealed vibration-proof device capable of avoiding leakage of liquid upon press fitting of an outer cylinder is provided. An intermediate ring interposed between the outer cylinder and an antivibratory base is formed at its outer circumferential surface with two projecting streaks, the one on liquid chambers side being formed with cutouts. When the outer cylinder is press fitted to an attachment opening of a vehicle body, the liquid confined in a space enclosed between both projecting streaks can escape to the liquid chambers, so that liquid never leaks outside.
