本考案はストラツトサスペンシヨンのスプリン
グシートラバーに関する。[Detailed Description of the Invention] The present invention relates to a spring seat rubber for a strut suspension.
ストラツトサスペンシヨンのシヨツクアブソー
バのシリンダと、該シヨツクアブソーバの車体側
連結部との間に弾装したコイルスプリングは並列
に配置されているため、車両の高周波振動に対し
ては剛体となつてしまい、振動が直接車体に伝わ
つてしまう。 Since the coil springs loaded between the cylinder of the shock absorber of the strut suspension and the coupling part of the shock absorber on the vehicle body side are arranged in parallel, they become rigid bodies against high-frequency vibrations of the vehicle. , vibrations are transmitted directly to the vehicle body.
そこで、このようなストラツトサスペンシヨン
にあつては、通常ストラツトサスペンシヨン上
側、即ち、車体側連結部分のスプリングシートに
スプリングシートラバーを介在させ、このスプリ
ングシートラバーで防振効果を得るようにしてい
る。 Therefore, in the case of such a strut suspension, a spring seat rubber is usually interposed in the spring seat on the upper side of the strut suspension, that is, the connecting part on the vehicle body side, and this spring seat rubber provides a vibration-proofing effect. ing.

る。 Figure 1 shows the structure of the upper part of the strut suspension.A shell 3 is fastened and fixed to the upper end of the piston rod 1a of the shock absorber 1 with a nut 4 via an insulator 2. It is fastened to the vehicle body panel 5.

ー９でコイルスプリング８の上端を受けて高周波
振動対策、即ち、シートラバー９の防振作用によ
りコイルスプリング８から直接単体５側に振動が
伝わらないようにしてある。 A spring seat 6 is fixed to the lower surface of the shell 3 (in some cases, it may be fixed to the upper end of the piston rod 1a), and between this spring seat 6 and a spring seat fixed to a cylinder (not shown). It is loaded with coil spring 8. A semicircular annular groove 7 is formed in the spring seat 6. A spring seat rubber 9 having a semicircular cross section is housed in the annular groove 7, and the seat rubber 9 receives the upper end of the coil spring 8 to generate high frequency vibrations. As a countermeasure, vibration is prevented from being directly transmitted from the coil spring 8 to the unit 5 side by the vibration-proofing action of the seat rubber 9.
ところが、このようにシートラバー９を介在さ

剛性を低めたものもあるが、このようにして剛性
を低めたものでも変形態様が圧縮となるため、そ
れ程防振効果が高まることはない。 However, even if the seat rubber 9 is interposed in this way, the seat rubber 9 is compressively deformed in response to vibration input, and therefore has relatively high rigidity, so that a good vibration damping effect cannot be obtained. Therefore, as shown in FIG. 2, there is a structure in which a plurality of grooves 10 are formed radially from the center of the seat rubber 9 at the top of the seat rubber 9 to reduce the rigidity. Since the deformation mode is compression even in the case of a material, the vibration-proofing effect will not be increased that much.

するため比較的剛性が高くなつてしまう点が指摘
されている。 For example, as disclosed in Japanese Utility Model Publication No. 49-15512, materials in which a butt member is bonded to an annular adjacent element are stacked on an annular support member, and a void is formed in the overlapping portion. However, it has been pointed out that the butt material is compressed and deformed, resulting in relatively high rigidity.

ものである。 In view of this conventional situation, the present invention provides a spring seat rubber that can shift its deformation from shear deformation to compressive deformation in response to vibration input, thereby reducing rigidity and further improving the vibration damping effect. It is something.
以下、本考案の実施例を図面と共に前記従来の
構成と同一部分に同一符号を付して詳述する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

および車体静荷重が作用した状態で前記環状溝７
との間に空隙１４を形成するようにしてある。 That is, in the present invention, as shown in the third figure, a spring seat rubber 9A having a substantially semicircular cross section is accommodated in the annular groove 7 of the spring seat 6 and receives the upper end of the coil spring 8, and is provided at the entire circumference of the top. The bottom part expands laterally, and a recessed part 11 is formed on each side to form lip parts 12 and 13 that protrude inward, respectively, and is housed in an annular groove 7 to which the force of the coil spring 8 and the static load of the vehicle body are applied. The annular groove 7 in the state
A gap 14 is formed between the two.

抑え耐久性を確保する。 With this configuration, when a vibration input is applied from the coil spring 8 side, the spring constant is small because the seat rubber 9A is sheared and deformed between the lip parts 12 and 13 until the gap 14 is collapsed in response to the vibration input. That is, since the rigidity of the seat rubber 9A is low, the vibration damping effect is increased. In this case, the seat rubber 9A is fixed to the inner peripheral surface of the annular groove 7 and does not move, and the lip portions 12 and 13 are attached to the seat rubber 9A.
It has the effect of improving sitting stability. and,
If the gap 14 collapses due to a large load, the lip portion 1
2, 13 and the entire seat rubber 9A are compressively deformed to act as vibration dampers, and also prevent tearing of the seat rubber 9A to ensure durability.

る。 As described above, according to the present invention, the sitting stability of the seat rubber can be improved by the lip portion, and the seat rubber can obtain a composite deformation characteristic of shear deformation and compressive deformation in response to vibration input. The practical effect is that the rigidity can be increased, and as a result, the vibration-proofing effect can be further demonstrated, providing a comfortable ride without causing a feeling of upheaval, and also preventing the generation of unpleasant vibration noise. has.
