Abstract:
An assembly mount for the movable fastening of a motor vehicle assembly (such as an engine) having a housing which is connectable to a motor vehicle body, a fastening bolt which is connectable to the motor vehicle assembly and which projects into the housing via a housing opening, a load-bearing spring which is connected to the housing and to the fastening bolt, wherein the load-bearing spring permits at least a relative movement of the fastening bolt in an opening plane of the housing opening within the housing opening, and a compensation element which is movable relative to the housing and relative to the fastening bolt and which serves for the variation of a movement clearance of the fastening bolt in the housing opening in the opening plane.
Abstract:
An active mount in which a nozzle plate is mounted between an insulator and a diaphragm to divide an inner space into an upper liquid chamber and a lower liquid chamber, and an encapsulated hydraulic liquid flows from the nozzle plate through a first flow path depending on a change in fastened state of the liquid chambers may include the nozzle plate having a second flow path and allowing the upper liquid chamber and the lower liquid chamber to be in communication with each other, the diaphragm made of a material having elasticity and coupled to a lower portion of the nozzle plate to form the lower liquid chamber, the diaphragm having an inflection portion, and a yoke including a body portion having an upper end in close contact with a lower portion of the inflection portion, and a rod portion coupled to a lower portion of the body portion.

Abstract:
A hydraulically damped mounting device has first and second anchor parts connected by a first deformable wall, and a working chamber for hydraulic fluid partially bounded by the first deformable wall. The working chamber is connected to a composition chamber for the hydraulic fluid by a first passageway, the composition chamber being partially bounded by a second deformable wall. There is also an auxiliary chamber partially bounded by a third deformable wall connected to the working chamber by a second passageway. The mounting device then has a vacuum chamber connectable to a vacuum source for varying the pressure in the vacuum chamber.
Abstract:
A fluid-filled tubular vibration-damping device comprising: an inner shaft member and an outer tube member connected by a main rubber elastic body so as to provide a sealed zone filled with a non-compressible fluid therebetween; and a partition wall partitioning the sealed zone axially. An outer peripheral side of the partition wall is fixed to the outer tube member while an inner peripheral side of the partition wall is constituted by an annular partition wall rubber disposed around the inner shaft member in a movable manner axially. Sealing tube parts are integrally formed with an inner peripheral portion of the partition wall rubber and project toward axially opposite sides. Fitting parts thicker than the sealing tube parts are integrally formed with distal ends of the respective sealing tube parts and are externally fitted around the inner shaft member in a slidable manner.

Abstract:
A fluid-filled vibration damping device including: a primary liquid chamber which gives rise to pressure fluctuations based on deformation of a main rubber elastic body at times of vibration input; an auxiliary liquid chamber which gives rise to pressure fluctuations relative to the primary liquid chamber at times of vibration input; and an orifice passage that allows flow action of a scaled fluid between the primary liquid chamber and the auxiliary liquid chamber. The sealed fluid contains at least 0.03 volume % of a dissolved gas under atmospheric pressure at room temperature. A low-adhesion energy surface with a water contact angle of at least 90 degrees is provided on an inner surface of the primary liquid chamber.
Abstract:
To provide a vibration isolation device capable of preventing the sealing performance in liquid filling work from deteriorating and capable of simplifying maintenance of apparatuses in relation with the liquid filling work.A liquid chamber is filled with liquid from a through hole 15 through a nozzle 41. A seal section is vulcanizingly formed in the periphery on one end side of the through hole 15. Because the seal section interferes with a nozzle 41 and is elastically deformed, the sealing performance in pouring in the liquid can be secured.Also, because the seal section is arranged for every vibration isolation device 10, maintenance of a liquid filling device 40 can be simplified compared with a case the seal section is arranged in the liquid filling device 40.
