Embodiment Construction
[0047] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0048] figure 1 , figure 2 A decompression cap 10 as a first embodiment of the present invention is shown in . The decompression cap 10 has a structure in which the first mounting member 12 and the second mounting member 14 are elastically connected by the main body rubber elastic body 16 . In the following description, in principle, the up-down direction refers to the figure 1 The up-and-down direction and the front-to-back direction refer to the direction that becomes the front-to-back direction of the vehicle when the vehicle is assembled. figure 2 In the left and right direction, the left and right direction refers to the left and right direction of the vehicle when the vehicle is assembled. figure 2 in the up and down direction.
[0049] More specifically, the first attachment member 12 is a highly rigid member formed of metal, synthetic resin, etc., and in...

The present invention provides a strut mount having a novel structure with which exceptional vibration-proofing performance can be achieved, and a suspension mechanism in which this strut mount is used. Provided is a strut mount 10 having a structure in which a first attachment member 12 attached to a shock absorber 72 and a second attachment member 14 attached to a vehicle body 74 are elastically linked to each other by a main body rubber elastic member 16, the strut mount 10 being provided with a fluid sealing area 60 inside of which an incompressible fluid is sealed, wherein an orifice passage 66 is formed through which the incompressible fluid sealed in the fluid sealing area 60 is caused to flow, a vibration-proofing effect based on the flowing action of the fluid is exhibited by the orifice passage 66, and the tuning frequency of the orifice passage 66 is set to the frequency of vibration transmitted to the vehicle body 74 via the shock absorber 72 when the automobile locks up.
Description
technical field [0001] The present invention relates to a strut mount mounted between a shock absorber and a vehicle body in a suspension device of an automobile and a suspension mechanism using the strut mount, and relates to the use of a flow action based on a fluid sealed inside A fluid-filled decompression cover with anti-vibration effect and a suspension mechanism using the decompression cover. Background technique [0002] Conventionally, various anti-vibration devices are used in automobiles for the purpose of achieving good ride comfort and the like. By arranging the vibration isolator between the vibration source constituting the vibration transmission system and the anti-vibration target part to prevent the vibration input from the vibration source from deteriorating the vibration state of the vibration-proof target part, when there is elastic deformation of the rubber elastic body The anti-vibration device that obtains the anti-vibration effect based on the energ...
