と樹脂シートとをすべらせる構造をとつていた。Prior Art This type of conventional suspension bushing generally has the structure shown in FIG. Metal inner cylinder 2
It had a structure in which the material and the resin sheet were slid together.
しかしながら、このタイプのサスペンシヨンブ
ツシユでは、金属内筒2とゴム部材1との間より
泥水が侵入し、樹脂シートと金属内筒2の接触面
にまで達し、金属内筒2の腐食や、樹脂シートの
摩耗を促進する恐れがあつた。 However, in this type of suspension bushing, muddy water enters between the metal inner cylinder 2 and the rubber member 1 and reaches the contact surface between the resin sheet and the metal inner cylinder 2, causing corrosion of the metal inner cylinder 2. There was a fear that this would accelerate the abrasion of the resin sheet.
考案の目的
本考案はかかる従来の欠点を解消すると共に従
来のサスペンシヨンブツシユよりその捩り剛性を
減少しながら耐久性をも向上したサスペンシヨン
ブツシユを提供することを目的とする。OBJECTS OF THE INVENTION It is an object of the present invention to provide a suspension bushing which eliminates the above-mentioned drawbacks of the conventional suspension bushings and has improved durability while reducing torsional rigidity compared to the conventional suspension bushings.
考案の構成
即ち、本考案の構成は、金属の内筒及び外筒を
備え、これら筒間に内筒側ゴムと、外筒側ゴムと
を設けると共にこれらゴム間の接触部の一部に樹
脂リングと金属リングとを介在接触させたことを
特徴とする。Structure of the invention That is, the structure of the invention includes an inner cylinder and an outer cylinder made of metal, an inner cylinder side rubber and an outer cylinder side rubber are provided between these cylinders, and a part of the contact area between these rubbers is made of resin. It is characterized in that the ring and the metal ring are brought into intervening contact.
考案の効果
従つて、本考案の構成によれば、接触部をゴム
部材間に形成すると共にその一部に樹脂リングと
金属リングとを接触したので、ゴム部材とゴム部
材との接触によりシール性能を向上することがで

小さいのでサスペンシヨンブツシユの耐久性をも
向上できる。Effects of the Invention Therefore, according to the configuration of the present invention, since the contact part is formed between the rubber members and the resin ring and the metal ring are in contact with a part of the contact part, the sealing performance is improved by the contact between the rubber members. At the same time, due to the contact between the resin ring and the metal ring, the frictional resistance can be reduced and the torsional rigidity can be reduced.Also, the sealing performance is good and the torsional rigidity is low, which increases the durability of the suspension bushing. can also be improved.
実施例
以下に本考案を図面の実施例に従つて説明す

この場合、外筒3に十分な絞り加工ができない時
は第2図に示すように外筒3に切割り7を設けて
サスペンシヨンアームに圧入する際にゴム部材に
圧縮が加わるようにする。 As shown in FIG. 2, an inner cylinder side rubber 5 is provided between a metal outer cylinder 3 having a flange portion and a metal inner cylinder 4.
and outer cylinder side rubber 6 are provided. The inner cylinder side rubber 5 is vulcanized and bonded to the inner cylinder 4, and the outer cylinder side rubber 6 is vulcanized and bonded to the outer cylinder 3.The outer cylinder side rubber 6 has the shape shown in FIG. The inner cylinder side rubber 5 is dimensioned to fit smoothly into the inner cylinder side. After inserting the inner cylinder side rubber 5 into the outer cylinder side rubber 6, a restriction is given to the metal outer cylinder 3, and when the product is completed, the outer cylinder side rubber 6 and the inner cylinder side rubber 5 are
Sufficient surface pressure is applied to the contact surface to form a seal.
In this case, if the outer cylinder 3 cannot be sufficiently drawn, a cut 7 is provided in the outer cylinder 3 as shown in FIG. 2 so that compression is applied to the rubber member when it is press-fitted into the suspension arm.
また、第2図及び第3図に示すように、外筒側
ゴム6は内周部の中央部に金属リング8を接着し

間に潤滑のためのグリース等を塗布する。 Further, as shown in FIGS. 2 and 3, the outer cylinder side rubber 6 has a metal ring 8 adhered to the center of the inner peripheral part, and the inner cylinder side rubber 5 has a resin ring 9 adhered to it. Unlike the contact between rubber members, the metal ring 8 and the resin ring 9 reduce their frictional resistance. Therefore, as can be seen from FIG. 2, a sufficient sealing effect is maintained at the contact portion between the inner cylinder side rubber 5 and the outer cylinder side rubber 6, and the torsional rigidity between the metal ring 8 and the resin ring 9 is reduced. In order to further reduce the torsional rigidity, grease or the like for lubrication is applied between the metal ring 8 and the resin ring 9.
