【考案の詳細な説明】
本考案は発泡ウレタン製のバウンドストッパに関し、さ
らに詳しくは自動車の懸架装置に設けられる揺動アーム
やリーフスプリングなどが、自動車が大きなバウンドを
したときに車体に突き当るのを防止する発泡ウレタン製
のバウンドストッパに関する。[Detailed Description of the Invention] The present invention relates to a bounce stopper made of urethane foam, and more specifically to prevent swinging arms, leaf springs, etc. installed in automobile suspension systems from hitting the vehicle body when the automobile makes a large bounce. This invention relates to a bounce stopper made of urethane foam that prevents.
前記のごときバウンドストッパとして、一般にはゴム製
のものが用いられていたが、ゴム製のバウンドストッパ
は重量が大きく、荷重と変位との間に自由度が少なく、
荷重を受けた場合に荷重の方向に直交する方向への変位
、すなわち横ぶれが大きい、など問題がある。Generally, rubber bound stoppers were used as the above-mentioned bound stoppers, but rubber bound stoppers are heavy and have little flexibility between load and displacement.
There is a problem in that when a load is applied, there is a large displacement in the direction perpendicular to the direction of the load, that is, there is large lateral wobbling.
前記問題を解消するために、発泡ウレタン製のバウンド

ライくとは異なり、金属製の車体への取付ブラケットを
溶着により取り付けることはできないので、成形特に、
取付ブラケットを埋設した形態で形成される。In order to solve the above problem, bound stoppers made of urethane foam have been used, but unlike bound stoppers made of rubber, these bound stoppers cannot be installed on metal car bodies. Since brackets cannot be attached by welding, molding, especially
It is formed with a mounting bracket embedded.
ところが、使用時に、発泡ウレタン製のバウンドストッ
パに荷重が及ぼされるとき、取付ブラケットを埋設した
部分と、このような埋設物のない発泡ウレタンの素材の

泡ウレタンとの間に剥離が生じてしまい、荷重と変位の
関係が満足できなくなってしまう、という事態が起こっ
ている。However, when a load is applied to the bound stopper made of foamed urethane during use, the degree of lateral wobbling is different between the part where the mounting bracket is buried and the part made only of the foamed urethane material without such buried objects. In some cases, cracks occur at the boundary, or separation occurs between the mounting bracket and the urethane foam, resulting in an unsatisfactory relationship between load and displacement.
そこで本考案は、発泡ウレタン製のバウンドストッパに
生じている前記問題を解消することを目的とする。Therefore, an object of the present invention is to solve the above-mentioned problems occurring in bound stoppers made of urethane foam.
本考案は、ポリウレタン製のストッパのウチ、取付ブラ
ケットが埋設された車体取付端部分から自由端に向けて
伸びる主体部分の外径が車体取付端部分の外径よりも小
に形成されていることを特徴とする。In this invention, the outer diameter of the main body part of the polyurethane stopper, which extends from the vehicle body attachment end where the mounting bracket is embedded toward the free end, is smaller than the outside diameter of the vehicle body attachment end. It is characterized by
以下に実施例を示す図面を参照して説明する。Examples will be described below with reference to the drawings.
第１図に示すように、本考案の発泡ウレタン製バウンド
ストッパ１０は、発泡ウレタンにより成形されたストッ
パ１２と、このストッパ１２内に埋設される金属製の取
付ブラケット１４とを含む。As shown in FIG. 1, the urethane foam bound stopper 10 of the present invention includes a stopper 12 made of urethane foam, and a metal mounting bracket 14 embedded within the stopper 12.
ストッパ１２は一方側が車体取付端１６に形成され、他
方側が自由端１８に形成されたもので、車体取付端１６
の近傍部分に取付ブラケット１４が埋設されている。The stopper 12 has one side formed at the vehicle body attachment end 16 and the other side formed at the free end 18.
A mounting bracket 14 is buried in the vicinity of.
取付ブラケット１４の中央には貫通孔２０が設けられて
おり、この貫通孔を通るボルトにより車体に取り付けら
れて使用に供される。A through hole 20 is provided in the center of the mounting bracket 14, and the mounting bracket 14 is mounted to the vehicle body using a bolt passing through the through hole.
ストッパ１２のうち、取付ブラケット１４が埋設された
車体取付端部分２２から自由端１８に向けて伸びる主体
部分２４の外径は、車体取付端部分２２の外径よりも小
に形成されている。The outer diameter of a main body portion 24 of the stopper 12 that extends from the vehicle body attachment end portion 22 in which the mounting bracket 14 is embedded toward the free end 18 is smaller than the outer diameter of the vehicle body attachment end portion 22.
本例のように、車体取付端部分２２から次第に外径の小
さくなる縮径部２６を経て主体部分２４の大部分を占め
る中間部２８へ、さらにこの中間部２８から第２の縮径
部３０を経て最も径の小さい先端部３２へ、という具合
に段階的に、主体部分２４の外径を車体取付端部分２２
の外径よりも小とすることもでき、あるいは車体取付端
部分２２から自由端１８へほぼ直線的に外径が小さくな
るように、主体部分２４を形成することもできる。As in this example, from the vehicle body attachment end portion 22, through a reduced diameter portion 26 whose outer diameter gradually becomes smaller, to an intermediate portion 28 that occupies most of the main body portion 24, and further from this intermediate portion 28 to a second reduced diameter portion 30. The outer diameter of the main body portion 24 is gradually adjusted to the vehicle body attachment end portion 22, and so on.
Alternatively, the main body portion 24 may be formed such that the outer diameter decreases approximately linearly from the body attachment end portion 22 to the free end 18.
要は、主体部分２４の外径が車体取付端部分２２の外径
よりも小となるように形成すればよい。In short, the outer diameter of the main body portion 24 may be smaller than the outer diameter of the vehicle body attachment end portion 22.
この場合、車体取付端部分２２から主体部分２４へ至る
境界は徐々に縮径されるように形成する。In this case, the boundary from the vehicle body attachment end portion 22 to the main body portion 24 is formed so as to be gradually reduced in diameter.
ストッパ１０の平面形状とか、その長さなどは任意に設
定する。The planar shape and length of the stopper 10 can be set arbitrarily.
前記のように形成された本考案のバウンドストッパ１０
は、例えば第２図に示すように、自動車の懸架装置にお
いて、取付ブラケット１４に設けられた貫通孔２０にボ
ルトを通して車体３４に取り付けられる。Bound stopper 10 of the present invention formed as described above
As shown in FIG. 2, for example, in an automobile suspension system, the mounting bracket 14 is attached to a vehicle body 34 by passing a bolt through a through hole 20 provided in a mounting bracket 14.
しかして自動車の走行中にバウンドすると、揺動アーム
３６が揺動し、バウンドの程度が小さなときは揺動アー
ム３６はバウンドストッパ１０に突き当らず、ばね３８
によってその揺動は減衰される。However, when the car bounces while running, the swing arm 36 swings, and when the degree of bounce is small, the swing arm 36 does not hit the bounce stopper 10 and the spring 38
The fluctuation is attenuated by
ところがバウンドの程度が大きくなって、設定した限界
を越えると、揺動アーム３６の***部４０がバウンドス
トッパ１０に突き当り、このバウンドストッパ１０に荷
重を付加することとなる。However, when the degree of bouncing increases and exceeds the set limit, the raised portion 40 of the swinging arm 36 abuts against the bound stopper 10, and a load is applied to the bound stopper 10.
その結果、バウンドストッパ１０は変形して横ぶくれを
呈することとなるが、主体部分２４は車体取付端部分２
２に比して軟らかなために大きく変形するのに対腰車体
取付端部分２２は変形し難く、わずかしか変形しない。As a result, the bound stopper 10 is deformed and exhibits lateral bulge, but the main body portion 24 is attached to the vehicle body attachment end portion 2.
2, it is softer and deforms significantly, but the end portion 22 that attaches to the vehicle body is difficult to deform and deforms only slightly.
従って、車体取付端部分に埋設されている取付ブラケッ
トと発泡ウレタン素材との相対的動きが少なくなって、
亀裂が発生する可能性は極めて少なくなる。Therefore, the relative movement between the mounting bracket buried in the mounting end of the vehicle body and the foamed urethane material is reduced.
The possibility of cracks occurring is greatly reduced.
本考案によれば、ゴム製のバウンドストッパの問題点を
解消するものでありながら、亀裂が生ずることによって
、バウンド抑止力を低下させるような事態の発生を有効
に防止するので、その機能は十分に発揮されることとな
る。According to the present invention, although the problem of the rubber bound stopper is solved, it effectively prevents the occurrence of a situation where cracks occur and reduce the bounce deterrent force, so its function is sufficient. It will be demonstrated.
