  • Patent number: 9676346
    Abstract: A fastener with an dampener is provided. The dampener is integrated with the fastener thus eliminating the need for an additional dampener installation. The fastener includes a shaft, a head connected to the shaft, and a dampener connected to the head. The dampener includes a piston and a compression chamber that is adapted to reduce vibration and noise when installed between two panels. The dampener is mounted to the underside of the head of a bolt, or to a trim piece. In other embodiments, the dampener is connected to the head of a clip. The dampener is adapted to rest between the head of a bolt and an adjacent panel thereby slightly spacing out the bolt head from the panel, such as sheet metal.

    Abstract: A vibration and shock isolator may include a resilient member and a compressing member. The resilient member may be connected between a vibrating source and an object. The compressing member may provide the resilient member with a compression displacement in accordance with the vibration characteristics applied to the resilient member from the vibrating source to change stiffness of the resilient member. Thus, a designed natural frequency of the isolator may be simply changed using the shape memory wire to suppress vibration amplification. As a result, the isolator may effectively relieve the shock and the vibration so that a structural stability of a structure may be ensured. Further, the isolator may have a simple structure so that the isolator may have improved reliability and durability.

  • Publication number: 20100007069
    Abstract: A vibration damping system (10) includes a laminated body (16) formed by alternately laminating rigid hard plates (12) and viscoelastic soft plates (14). At both ends in the laminating direction, the laminated body (16) is connected to a vibration generation section and a vibration receiving section, respectively. The soft plate (14) arranged in a region subjected to a higher isostatic stress is made thicker than the soft plates (14) arranged in other regions. Even when the vibration damping system (10) is applied with vibration having a large amplitude and prying deformation is thereby caused, the soft members (14) are prevented from isostatic fracture to provide a significantly improved durability of the vibration damping system (10).

  • Patent number: 7540479
    Abstract: There is provided a vibration damping device including; a pair of rubber arm portions connecting an inner fitting and an outer fitting to each other in the horizontal direction; and a rubber leg portion connecting in the vertical direction; the paired rubber arm portions are formed so that the thickness thereof decreases gradually from the inner fitting side toward the outer fitting side, and the rubber leg portion is formed so that each of both side surfaces is formed by an inwardly depressed curved surface, and is formed into a curved broaden shape toward the outer fitting side. Thereby, a spring constant in the horizontal direction is increased advantageously while a spring constant in the vertical direction kept large, and the durability of the rubber elastic body can be increased effectively.

  • Publication number: 20080128966
    Abstract: A damping ring is provided for isolating vibration between a fixing member and a structure. The damping ring includes a body and a protruding lip formed on the body. The body is installed on the structure and has a through hole opened along the central axis of the body, and the through hole is provided for the fixing member to be inserted therein. The protruding lip is formed on the edges of a opening of the through hole and surrounds the opening, and the protruding lip extends outwardly along the central axis of the body, and extends inwardly along the radial direction, so as to contact with the fixing member, such that a gap is formed between the fixing member and the body instead of directly contacting the fixing member with the body, thus vibration transmitted between the fixing member and the structure is cushioned and isolated.

  • Patent number: 7296786
    Abstract: A composite bushing including an outer sleeve coaxially surrounding an inner sleeve, and including an elastomeric body extending between the outer sleeve and the inner sleeve. The elastomeric body is provided with circumferentially alternating wedge sections having different physical characteristics, so as to provide a bushing having directional differences in resistance to deflection. The resiliency in a first radial direction appreciably differs from the resiliency in a second radial direction, where the second radial direction is at an angle to the first radial direction. The resulting bushing configuration can be used to attenuate vibration and noise in a vehicle, and thereby contribute to improved vehicle handling and ride comfort.

  • Patent number: 7232118
    Abstract: A fluid filled vibration-damping device includes an elastic body disposed between a first mounting member and a second mounting member and partially defines a fluid chamber having a non-compressible fluid sealed therein, and exhibits vibration damping action on the basis of flow action of the non-compressible fluid created within the fluid chamber during vibration input. At least one mounting member from among the first and second mounting members is formed independently of the elastic body and is disposed in abutment with the elastic body in an initial load acting direction, while making the mounting member displaceable away from the rubber elastic body in a opposite direction from the initial load acting direction. A rebound stop mechanism for limiting displacement of the mounting member away from the rubber elastic body in a cushion-wise fashion is disposed between the first and second mounting members.
