Title:
VIBRATION DAMPER
Document Type and Number:
WIPO Patent Application WO/2013/140700
Kind Code:
A1
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 (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 (431), 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 torsional direction and the compression component of the rubber base (430) in the direction perpendicular to the axis (O). Consequently, the spring constant in the direction of the axis (O) can be increased while reducing the spring constant in the torsional direction and the spring constant in the direction perpendicular to the axis (O).
