    摘要: A vibration isolation rubber composition containing the following components (B) to (E) together with a rubber compound made of the following (A) is produced, which makes it possible to highly satisfy both heat resistance and the reduction of dynamic magnification factors. The vibration isolation rubber composition containing (A) a diene-based rubber containing natural rubber as a main component, (B) a filler, (C) a hydrazide compound, (D) a disulfide compound represented by General Formula (1), and (E) a sulfur-based vulcanizing agent. [In General Formula (1), a ring A and a ring B each indicate a nitrogen-containing heterocyclic group having 4 to 24 carbon atoms.]

    摘要: The disclosure introduces a multi-layer automotive tube, said layers comprising an inner layer made of thermoplastic polyurethane (TPU); a first intermediate layer made of ethylene vinyl alcohol (EVOH); a second intermediate layer made of polyamide and an outer layer made of polyamide. The inner layer made of TPU provides excellent chemical stability and is significantly less susceptible to degradation caused by frequent contact with fuels and/or fuel vapors. Said automotive tube can be produced using methods widely known in the prior art, such that industrial lines for producing said automotive tube can be adapted without great difficulty.

    摘要: A stabilizer bushing including: a stabilizer bar; and two semi-tubular elastic half bodies each including an intermediate plate fitting of semicircular arc shape embedded therein. The elastic half bodies are bonded to an outer circumferential surface of the stabilizer bar such that two circumferential end faces thereof are mutually butted. The plate fitting is embedded in an axial direction. A notch-shaped recess is provided in a corner of axial ends of the circumferential end faces of each elastic half body. The recess extends in a radial direction of the elastic half body and opens onto an inner circumferential surface thereof, and a corner of axial ends of circumferential end portions of the plate fitting is exposed at the recess. A bottom corner of the recess extending in the radial direction of the elastic half body has a curved-concave inner surface shape.

    摘要: A bearing bush and a method for producing a bearing bush are provided. The bearing bush includes a core element, an elastomer element, a cage element and a sleeve element. The cage element is at least partially embedded in the elastomer element. The elastomer element elastically connects the cage element and the core element to each other. The core element, the cage element and the elastomer element form a pre-assembly element. One of the sleeve element and the cage element includes a protrusion. The other of the sleeve element and the cage element includes a groove, which is engageable with the protrusion, in an assembled state of the bearing bush. The pre-assembly element is fixed in the sleeve element. The protrusion and the groove form a two-point contact in a cross-section.

    摘要: A vibration damper including a plate-shaped metal bracket having an attachment, and first and second extended parts extending from the attachment toward mutually opposite sides. Edge flanges rise from both widthwise edges of the attachment across its entire length. The first extended part includes the edge flanges extending continuously from the attachment and a pair of rising walls rising on both widthwise sides thereof. A first dynamic damper including a pair of support rubber elastic bodies and a mass member is provided between the rising walls. The second extended part includes a rising supporter rising from its end and the edge flanges being continuous with the attachment across its entire length including the rising supporter. A second dynamic damper including an inner shaft member and an outer mass member elastically connected by a main rubber elastic body is attached to the rising supporter.

    摘要: A fluid-filled vibration damping device including a partition having a housing area, and a movable film housed in the housing area while including a central retainer held by the partition and spoke-shaped retainers extending radially outward from the central retainer. A first surface of the movable film is overlapped on a wall inner surface of the housing area. An elastic deformation zone provided circumferentially between the spoke-shaped retainers is allowed to deform in a direction away from the wall inner surface, and includes a cushion ridge projecting from a second surface of the movable film while extending radially outward from the central retainer. A height of the cushion ridge is varied in a direction of extension such that a timing of contact with an opposing wall inner surface in the housing area varies depending on an amount of deformation of the elastic deformation zone.

    摘要: A multilayer tube (1) includes: an elastic layer (11, 21, 31, 41, 51) formed over the entire length of the multilayer tube (1) and having a predetermined flexural modulus of elasticity; and a hard layer (12, 22, 32, 42, 52) formed over the entire length of the multilayer tube (1), having a flexural modulus of elasticity that is high compared to the elastic layer (11, 21, 31, 41, 51), and disposed more to an outer layer side than the elastic layer (11, 21, 31, 41, 51). A first extremity (10) of the multilayer tube (1) is formed in such a manner that the thickness (H11) of the elastic layer (11) is thicker than the thickness (H12) of the hard layer (12).
