Reference numeral 1 denotes a laminated body in which a large number of metal plates 52 and main body rubbers (rubbers) 53 are alternately laminated and sandwiched by mounting metal plates 56a and 56b from above and below.

積層したもの等があった。In the conventional laminated anti-vibration rubber 51, through holes are provided in the laminated body in the axial direction in order to adjust the spring constant and to pass the pre-compression bolt of the main rubber 53. Also, in order to make the compression and shear spring constants work in combination with respect to the vertical load, there are a plurality of bent or curved metal plates 52 and main body rubbers 53 alternately laminated.

質を有している。このため、乗り心地の悪い方向の荷重
を、圧縮方向の方よりも剪断方向の方で多く受けようと
すると、荷重に比例して変位が大きくなっていた。The conventional laminated rubber vibration isolator has a property that the spring constant in the shearing direction becomes smaller as the compressive load (displacement) becomes larger. On the other hand, the shear spring constant has a property that it hardly changes regardless of the shear load (displacement) as compared with the spring constant in the compression direction. Therefore, when an attempt is made to receive a load in the direction in which the ride comfort is poor in the shearing direction rather than in the compression direction, the displacement becomes large in proportion to the load.

に座屈現象が発生するため、圧縮荷重（変位）を抑えた
り、本体ゴムの厚さｄと積層型防振ゴムの受圧面の一辺
の長さｌとの比（ｄ／ｌ）を小さくする必要があった。However, when a certain displacement is exceeded, as shown in FIGS. 8 (a) and 8 (b), a buckling phenomenon occurs in the laminated anti-vibration rubber, so that the compressive load (displacement) is suppressed, It was necessary to reduce the ratio (d / l) between the thickness d of the main rubber and the length l of one side of the pressure-receiving surface of the laminated vibration-proof rubber.

Considering the strength, pre-compression is applied so that tensile stress is not applied to the bonding surface between the rubber and metal plate, and a certain angle is provided with respect to the load direction so that compressive displacement occurs during shear deformation. I was using it.

寸法以下となり、必然的に変位を大きくとれなかった。When pre-compression is applied, for example, two laminated anti-vibration rubbers are used per supporting point. At this time, the threaded compression shaft is inserted into the above-mentioned through hole provided for adjusting the spring constant, and the female screw on the lower surface of the laminated anti-vibration rubber formed so as to be screwed with the screw of the shaft. The pre-compression was applied to the laminated anti-vibration rubber by screwing it on. For this reason, the allowable displacement in the shearing direction is equal to or smaller than the dimension of the laminated anti-vibration rubber, and the displacement cannot necessarily be large.

However, considering the space of the entire vehicle, these methods are realized. It was impossible and, as a result, a large displacement could not be taken, resulting in a high spring constant and poor riding comfort.

好な乗り心地を得るべく、積層型防振ゴム１にかかる荷
重の剪断方向の変位成分を大きくして設ける。At this time, for example, in order to improve the ride comfort in the left-right direction, it is common to arrange the laminated type vibration-damping rubber 1 so that the shearing direction thereof coincides with the left-right direction of the vehicle. It is placed at an angle of attachment θ with respect to the direction. This is to reduce the tensile stress in the bonded portion between the mounting metal plates 6a, 6b and the main rubber 3 by decomposing the displacement (deflection) in the shear direction into the displacement component in the shear direction and the displacement component in the compression direction. It is intended. Further, this mounting angle θ is set by increasing the displacement component in the shearing direction of the load applied to the laminated anti-vibration rubber 1 in order to obtain a large ride in the lateral direction of travel of the vehicle and obtain a good ride comfort.
【００２５】したがって、積層型防振ゴム１において、
取付角度θが大きくなるほど、車両進行左右方向の荷重
に対する剪断方向の反力は大きくなり、車両進行左右方
向の荷重に対する圧縮方向の反力は小さくなる。Therefore, in the laminated anti-vibration rubber 1,
As the mounting angle θ increases, the reaction force in the shearing direction with respect to the load in the lateral direction of the vehicle increases, and the reaction force in the compression direction with respect to the load in the lateral direction of the vehicle decreases.
【００２６】本発明の積層型防振ゴム１は、圧縮及び剪
断荷重を受けることによってある一定の変位（たわみ）

方向の変形を阻止するため、座屈変形が生じない。The laminated anti-vibration rubber 1 of the present invention undergoes a certain displacement (deflection) when subjected to a compressive and shearing load.
Even if it exceeds, the buckling deformation does not occur because the shaft 4 inserted in the through hole 9 prevents the deformation in the shearing direction.

However, when the deflection in the compression direction progresses and exceeds a certain value, the reaction force of the compression rubbers 5 and 5 also starts to work, and the compression rubbers 5 and 5 at both ends of the shaft 4 in the through hole 9 are moved to the shaft 4 As a result of the compression, the reaction force is increased and the deflection is greatly reduced, so that the deformation (deflection) can be stopped within the allowable displacement.

時に圧縮用ゴム５，５の反力が働き始める。In the laminated anti-vibration rubber of the present invention, the shaft 4 is inserted after the through hole 9 is formed, but the shaft 4 which has been subjected to the mold release treatment so as not to adhere to the main body rubber 3 in advance is used. Embedded in the core 4, and a large number of metal plates 2 having a hole having the same diameter as the shaft 4 and a body rubber 3 are alternately laminated in the center, and finally a body rubber 3 having no hole is laminated. The shaft 4 may be confined inside the laminated body. In this case, the compression rubber 5,
Since 5 is formed as a part of the laminated body, the reaction force of the compression rubbers 5 and 5 starts to work simultaneously with the compression deformation.
