  • Patent number: 10316920
    Abstract: A vibration damper, which enables a spring constant in the axial direction to be increased while reducing a spring constant in the torsional direction and a spring constant in the direction perpendicular to the axial direction, is provided. With dividing surfaces of first rubber parts and dividing surfaces of second rubber parts separated from each other in the direction of the axis, and spaces formed between the dividing surfaces, first outer cylinder parts and second outer cylinder parts are held and fixed by cylindrical members. Using the spaces between the dividing surfaces of the first rubber parts and the dividing surfaces of the second rubber parts, a compression component of the rubber base in the direction of the axis can be maintained while suppressing a shear component of the rubber base in the torsional direction and the compression component of the rubber base in the direction perpendicular to the axis.

  • Publication number: 20150014906
    Abstract: A vibration damper, which enables a spring constant in the axial direction to be increased while reducing a spring constant in the prying direction and a spring constant in the direction perpendicular to the axial direction, is provided. With dividing surfaces of first rubber parts (431) and dividing surfaces of second rubber parts (432) separated from each other in the direction of the axis (O), and spaces (SP) formed between the dividing surfaces, first outer cylinder parts (421) and second outer cylinder parts (422) are held and fixed by cylindrical members (440). Using the spaces (SP) between the dividing surfaces of the first rubber parts (431) and the dividing surfaces of the second rubber parts (432), a compression component of the rubber base (430) in the direction of the axis (O) can be maintained While suppressing a shear component of the rubber base (430) in the prying direction and the compression component of the rubber base (430) in the direction perpendicular to the axis (O).

  • Publication number: 20020041064
    Abstract: A bushing type mount comprising an inner cylinder, an outer cylinder and a rubber-like elastomer interposed between the both cylinders, the outer cylinder being, at axially one extremity side, bent inwardly to form an inner flange, the inner flange being inclined at an intersecting angle made by its flange plane and the axial line of the inner cylinder of 60 to 85 degree, whereby it is possible to reduce a difference between a compressive deformation strain of the elastomer due to the inner flange and a shearing deformation strain occurring around the inner cylinder inboard of the inner flange and to suppress the occurrence of cracking to the utmost, thus enhancing the durability.
