本考案は主として自動車用懸架装置に用いられ

とができず耐久性が劣る欠点があつたのである。 Conventionally, when a cylindrical vibration isolator is used for the attachment part of a suspension arm to the vehicle body, the rigidity in the direction perpendicular to the axis is changed in the front, rear, top, bottom, left and right of the vehicle, and in order to increase the difference, the vibration isolator is shown in Figure 4. Nusumi 1 was set up like this. (For example, see Utility Model Application Publication No. 56-85742). However, with such a structure, the inner cylinder 2
As the load is repeatedly applied between the outer cylinder 3 and the elastic body 4
Cracks occur at the edges of the pads 1, and the compressibility of the elastic body 4 cannot be increased to form the pads 1, resulting in poor durability.

きる。 The present invention has been made to solve the above-mentioned drawbacks. Its unique feature is that the elastic body is divided into parts, and the elastic body glued to the inner cylinder is surrounded by the elastic body glued to the two-split outer cylinder, which is press-fitted into the mounting boss. It is in. With such a structure, by changing the type and physical properties of the inner cylinder side elastic body and the outer cylinder side elastic body, and increasing the press-fit ratio, the rigidity ratio in the axis-perpendicular direction and in the axial direction can be set large. In addition, the occurrence of cracks can be reduced and durability can be improved.
以下図面によつて、本考案の構造及び特徴を詳

きる。 The drawings illustrate the present invention, in which FIG. 1a is an exploded perspective view of a vibration isolator, and FIG. 1b is a cross-sectional view. FIG. 2 shows another embodiment, and is a perspective cross-sectional view. As is clear from these figures, the vibration isolator consists of an inner elastic body 6 bonded to the outer surface of the inner cylinder 5.
and an outer cylinder 7a that is divided into two parts approximately along the axial direction.
The outer cylinders 7a and 7b are each attached with the inner elastic body 6 being sandwiched between the outer elastic bodies 8a and 8b. It has a structure in which it is press-fitted into the mating boss 9. The inner elastic body 6 bonded to the inner cylinder 5 has the purpose of changing the rigidity in the direction perpendicular to the axis. By forming it from high hardness rubber or plastic, the rigidity ratio in the direction perpendicular to the axis, that is, in the Y direction and the Z direction shown in FIG. 2 can be greatly changed. Furthermore, when the outer elastic bodies 8a, 8b are made of high-rigidity resin, by sliding between the inner cylinder 5 and 8a, 8b, the rigidity ratio in the X direction and the Y direction can be made extremely large.

きる。 FIG. 3 is a graph showing the relationship between load and deflection. The Y direction indicates the outer elastic body 8a,
8b shows. This is the stiffness in the direction perpendicular to the axis. The line that is featured in this graph is in the X direction. The chain line shows the X of the conventional product when the rigidity in the Y direction is the same.
directional stiffness. However, in the case of the product of the present invention shown by the solid line, the rigidity can be lowered compared to the conventional product. In other words, the outer elastic bodies 8a, 8
By creating a hardness difference between b and the inner elastic body 6 and highly compressing the elastic bodies 6, 8a, 8b, especially the inner elastic body 6, rigidity in the axial direction with respect to the Y direction perpendicular to the axis can be achieved. I was able to lower it. This axial rigidity can be achieved by sliding between the inner cylinder 5 and the high-hardness elastic bodies 8a and 8b, and as shown in FIG.
This can be further reduced by providing a gap 10 between the outer elastic bodies 8a and 8b.

る。 In this way, the product of the present invention has the versatility of being able to change its rigidity also in the axial direction. For example, when this is used in a suspension arm, the spring constant in the lateral direction of the vehicle can be made stiffer, while being softer in the vertical and longitudinal directions, contributing to improved running stability and ride comfort.

きたのである。 The product of the present invention is characterized by further improved durability. That is, compared to conventional products, since the outer cylinder is of a split type, high compression can be applied to the elastic bodies 6, 8a, and 8b, resulting in improved durability. In addition, as mentioned above, in the case of conventional products with padding, cracks occurred at the edges of the padding, but the product of the present invention solves this problem and improves durability.
