て僅かに移動可能に遊嵌したことある。Various elastic bushings have been proposed that provide vibration damping between an inner cylinder and an outer cylinder via an elastic body. The present invention improves such an elastic bushing so that the damping is small during normal driving and becomes large when an excessive impact is applied. The present invention relates to the provision of an elastic bushing which is also excellent in the performance of force and force. A fluid chamber is formed by going around the inside and enclosing C, and the fluid chamber is extended in the axial direction by two:
An orifice link having separate communication holes has been loosely fitted so as to be slightly movable in the axial direction.
以下図面によって本発明の詳細な説明する。The present invention will be explained in detail below with reference to the drawings.

グリース、水、空気等である。The illustrated elastic bushing has an UT structure in which damping is applied in the axial direction via an elastic body (3) between the inner cylinder (1) and the outer cylinder (2), and there is a fluid inside the elastic body (3). (4) A sealed fluid chamber (5) is formed around the circumference. Therefore, in this example, the elastic body is divided into an outer elastic body (3a) and an inner elastic body (3b), and a middle ring (9) is interposed between these. And inside wJ(1
), a stopper sleeve (10) is provided on the outer periphery of the stopper sleeve (10), a loose fitting groove (6) is provided in the stopper sleeve (10), and a fluid chamber (5) is arranged around the 2/IJ
The orifice ring (7) is loosely fitted so that it can be moved slightly in the axial direction. As shown in Figure 3, this orifice ring (7) has a large flow resistance when the communication hole (8) (orifice) opens from the - side and detours through the inside to the other side. Therefore, it is effective. Moreover, a plurality of communication holes (8) can be provided to change the performance depending on the size and number of the communication holes (8). The fluid filled inside is made of silicone oil, glycol, etc. that does not swell the rubber or corrode the inside of the elastic bushing.

ない為に減衰は生じない。The functions and effects of the elastic bushing described above are as follows. In other words, when the outermost cylinder (2) is fixed and the innermost cylinder (1) is moved in the X (+) direction in the figure, the orifice ring does not move at first due to fluid resistance, and the inner cylinder (1)
Only the stopper sleeve (10), which is coaxially arranged and fixed, moves. During this time, two fluid chambers (5) (5')
Since no volume change occurs between the two and no fluid passes through the communication hole (8), no attenuation occurs.

), causing damping. Furthermore, in the present invention, in order to ensure the elasticity of the elastic bush in the direction perpendicular to the axis, it is also possible to arrange an outer elastic body (3a) around the outer periphery of the intermediate ring (9). In addition, a groove is provided on the outer periphery of the ring so that the orifice ring can easily move in the axial direction when a force is applied to the elastic bushing in the direction perpendicular to the axis and the inner cylinder (1) is also loaded in the axial direction. You can also do that.

ある。As described in detail above, the present invention provides an orifice ring by arranging a swivel sleeve (10) on the outer periphery of the inner cylinder, providing a loose fit groove therein, and providing an appropriate gap on the inner periphery or both ends. is loosely fitted into the outer periphery of the loose fitting groove, so that when a small amplitude is applied between the outer cylinder and the inner cylinder in the axial direction, little attenuation occurs, and conversely, when a large amplitude is applied, a large attenuation occurs. As a result, we were able to provide a high-performance elastic bushing with excellent characteristics.
