本発明はエンジンマウントのような弾性支持体に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to resilient supports such as engine mounts.
ゴムブロックを２個の取付金属の間に介在させた周知の
防振支持体では、ゴムの損失係数が小さし・ので、減衰
係数が小さい。In the well-known anti-vibration support in which a rubber block is interposed between two mounting metals, the loss coefficient of the rubber is small, so the damping coefficient is small.
エンジンマウントとしては低周波域（１５ＨＺ近辺）で
の減衰係数が大きく、高周波城（１００ＨＺ近辺）での
動的バネ定数が小さいことが要求される。このような要
求に応ずるために、ゴムの弾性と流体の流通抵抗を利用
した弾性支持体が、特公昭４８一３６１５１号公報及び
袴公昭５２一１６５５４号公報により提案されている。The engine mount is required to have a large damping coefficient in the low frequency range (near 15Hz) and a small dynamic spring constant in the high frequency range (near 100Hz). In order to meet such demands, elastic supports utilizing rubber elasticity and fluid flow resistance have been proposed in Japanese Patent Publication No. 48-136151 and Hakama Publication No. 52-16554.

る。However, in this elastic support, the two chambers connected by a communication passage and filled with fluid are mostly surrounded by inner and outer hard metal cylinders, and the volume change of the rubber part due to the vibration stroke is relatively small. , because of this, the flow rate of fluid is small,
It is difficult to take distribution resistance freely. In addition, any part of the rubber surrounding the two chambers filled with fluid' is used as a load support, so it is difficult to deform and suppresses the flow of fluid. Therefore, from this point of view as well, there is a drawback that the fluid flow resistance cannot be fully utilized. The present invention aims to solve these problems and provide a further improved vibration-proof support of this type.

弾性体からなる円筒状の肉厚の筒体である。In order to achieve this object, the present invention integrally provides mounting metals for closing the ends of a thick cylindrical body made of a rubber elastic body at both ends thereof, and at least one of the mounting metal fittings is provided inside the cylindrical body. A small hole for allowing the lotus to pass through to the outside, and an enclosure having a sheet-like part separated from the small hole and at least partially made of a rubber elastic body are integrally formed, and the inside of the cylinder and the enclosure that are conveyed through the small hole are integrally formed. A vibration isolating support is constructed in which a fluid is sealed in the cylindrical body and a member is provided for suppressing outward deformation when the cylindrical body is compressed in the direction of extension of the center line. FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a thick cylindrical body made of rubber elastic material.

を大きく縮小できる。A mounting part 2 is attached to one end of the cylinder 1 so as to close the end of the cylinder 1.
A mounting bracket 2 having a mounting portion 3a is integrally provided at the end of the cylindrical body 1, and a mounting bracket 3 having a mounting portion 3a is also integrally provided so as to close the end of the cylindrical body 1. The mounting bracket 3 is provided with a small hole 4 through which the inside la of the cylindrical body 1 is communicated to the outside. On the opposite side of the mounting bracket 3 to the cylindrical body 1, an enclosure 6 made of a rubber elastic body, which is spaced apart from the small hole 4 and partially forms a sheet-like portion 5, is arranged so as to form a chamber 5a on the outer surface of the small hole 4. It is formed integrally with the mounting bracket 3. Further, a band 7 made of fiber or a thin metal plate is iron-bonded to the outer periphery of the cylinder 1 so as to surround the central portion of the cylinder 1. The interior la and chamber 5a of the cylindrical body 1 are filled with a fluid such as water.
FIG. 2 shows another embodiment of the present invention, in which both ends of the cylindrical body 1 are formed into outwardly inclined conical surfaces, and the parts of the mounting brackets 2 and 3 that contact the cylindrical body 1 are formed into a circular shape. It has conical surfaces 2b and 3b which are inclined inwardly and coincide with both ends of the body 1, and other than this, it is almost the same as the embodiment shown in FIG. In the above embodiment, when the external force P acts to bring the mounting brackets 2 and 3 closer together and the cylinder 1 is compressed to the chain line S in the direction of extension of the center line of the cylinder 1, the belt-like band 7 In the absence of the conical surfaces 2b and 3b, the cylindrical body 1 deforms freely, but the presence of these suppresses the outward deformation, as shown by the curved chain lines in Figures 1 and 2. It deforms mainly inward, and the volume of the interior la of the cylinder 1 can be greatly reduced.

る。Furthermore, as the volume of the interior la decreases, the fluid in the interior la flows into the chamber 5a through the small hole 4, but the wall of the chamber 5a is
Since the sheet-like part 5 made of a rubber elastic body that can be deformed independently of Since the small hole 4 is deformed to increase the
The outflow of fluid to the outside and the inflow of fluid into the interior la can be easily performed. It goes without saying that the hole 4 and the enclosure 6 may also be provided on the mounting bracket 2 side. Therefore, according to the present invention, it is possible to move around the vibration-proof support body in which the flow resistance of the fluid passing through the small hole 4 can be arbitrarily designed, and the damping coefficient at the low frequency castle is much larger than that of the conventional vibration-proof structure. It can provide support.
