するジヨイントブーツの改良に関するものである。[Detailed description of the invention] The present invention is designed to provide a constant velocity joint for a drive shaft used in, for example, a front engine/front drive vehicle (F-F vehicle) or a four-wheel independent suspension vehicle. The present invention relates to an improvement in a joint boot that closes an opening in a side member.
一般に、前記のごときＦ−Ｆ車や四輪独立懸架車におい
ては、例えばフロントアクスルのドライブシャフトのジ
ヨイントとして等速ジヨイントを使用している。Generally, in F-F vehicles and four-wheel independent suspension vehicles as described above, a constant velocity joint is used, for example, as a joint for a drive shaft of a front axle.

部材との衝突やごみ等の侵入から保護するためにジヨイ
ントブーツ４および５で覆っている。That is, as shown in Fig. 1, the drive shaft of the front axle of a vehicle is provided with a joint 2 on the outball side (wheel side) of a joint shaft 1, and a joint 3 on the inboard side (reference side). In addition, each of these joints 2 and 3 is covered with joint boots 4 and 5 to protect them from collision with other members and intrusion of dirt and the like.

フトのジヨイント２を構成する外方部材６の開口部の外
周に固定され、一方小径開口部４Ｂはクランプ８により
ジヨイントシャフト１の一部に固定されている。For example, as shown in FIG. 2, the joint boot 4 is fixed to the outer periphery of the opening of the outer member 6 constituting the joint 2 of the drive shaft by a clamp 7 at the large diameter opening 4A, while at the small diameter opening 4B. is fixed to a part of the joint shaft 1 by a clamp 8.
それにより、外方部材６の開口部はジヨイントブーツ４
で完全に閉塞された状態となっている。Thereby, the opening of the outer member 6 is connected to the joint boot 4.
It is completely blocked.

も損傷が及ぶ恐れが非常に強い。In such a case, the outer peripheral surface of the joint boot 4 may be damaged by the impact force caused by the direct collision with the edge portion of the steering knuckle stopper, etc., and the opening of the outer member 6 made of a rigid material may be damaged. Since the large diameter opening 4A located on the outer periphery is sandwiched between the edge part of the steering knuckle stopper etc. and the outer member 6, there is no space to escape from the impact force, and the inner periphery as well as the outer periphery have no space to escape from the impact force. There is a high risk of damage to the surface and interior.
本考案はこのような不具合を解消するためになされたも

である。The present invention was developed to eliminate such problems, and when a constant velocity joint is installed or removed from a vehicle, the joint boot may collide with other parts and be damaged, or the joint boot may be damaged during driving. The purpose of this is to prevent damage due to the impact force of flying stones etc. with a simple structure.
この目的を達成するため、本考案による等速ジヨイント

を特徴とするものである。In order to achieve this purpose, the joint boot for constant velocity joint according to the present invention has a large diameter opening attached via a fixture around the outer member constituting the joint part of the constant velocity joint, and In a joint boot that closes an opening of a member, a portion of a protective cover that can be reversed to the outer circumferential side of the large diameter opening of the joint boot that covers the opening of the outer member via an inversion part. It is characterized by being integrally formed.
以下、本考案を図面に示す実施例に従ってさらに説明す
る。Hereinafter, the present invention will be further explained according to embodiments shown in the drawings.

いる。As is clear from the figure, it is located at one end of the main body of the joint boot 4, and the joint boot 4 is sometimes assembled around the opening of the outer member that constitutes the joint part of the constant velocity joint. At the end of the large-diameter opening 4A, a protective cover portion 4C integrally and annularly protrudes outward from the large-diameter opening 4A is made of a material such as rubber, similar to the main body of the joint boot 4. It is integrally formed.

いる。This protective cover part 4C has a slightly thick bead-shaped part on the tip side, but in actual use, the large diameter opening 4A
Since it is used by being inverted toward the outer circumferential side of the joint boot 4, it is formed thinner overall than the main body portion of the joint boot 4, and an inverted portion 4D is formed at the joint with the large diameter opening 4A. .
つぎに、この保護カバ一部４Ｃの作用について説明する
。Next, the function of this protective cover portion 4C will be explained.

開口部４Ａの外周側に反転させられる。That is, the protective cover portion 4C is integrally molded on the distal end side of the large diameter opening 4A of the joint boot 4 as shown in FIG. After assembling with clamp 7 on the outer circumference side,
As shown by arrow A in FIG. 3, it is reversed to the outer peripheral side of the large-diameter opening 4A at the reversing portion 4D.

衝撃力から保護する緩衝材の役目を果たす。After this reversal, the protective cover portion 4C is in the state shown in FIG. 4, and the large diameter opening 4A of the joint boot 4 is
It completely covers a portion of the main body of the joint boot 4 from the outer periphery of the joint boot 4, and serves as a cushioning material that protects the large diameter opening 4A from impact force.
そして、反転部における保護カバ一部４Ｃの内周面と大
径開口部４Ａの外周面との間には第４図に示すように寸
法１の空間Ｇが形成される。A space G having a dimension of 1 is formed between the inner circumferential surface of the protective cover portion 4C and the outer circumferential surface of the large-diameter opening 4A at the reversal portion, as shown in FIG.
この空間Ｇは緩衝作用を持つものであり、例えば車両へ

バ一部４Ｃの外周面に直接ぶつかったような場合でも、
衝撃力が該保護カバ一部４Ｃから大径開口部４Ａに直接

。This space G has a buffering effect, so that if other parts such as a steering knuckle stopper directly collide with the outer circumferential surface of the protective cover part 4C, for example, when assembling or removing the constant velocity joint from the vehicle, etc. but,
It functions to prevent impact force from being directly transmitted from the protective cover portion 4C to the large-diameter opening 4A, and to absorb the impact force.
もちろん、前記保護カバ一部４Ｃ自体は該保護カバ一部
４Ｃの存在により、ジヨイントブーツ４の大径開口部４
Ａおよび本体部分の一部に対して他の部品の衝突による
衝撃力が直接的に加わって該ジヨイントブーツ４の損傷
を生じるのを有効に防止することが可能である。Of course, the protective cover part 4C itself has a large diameter opening 4 of the joint boot 4 due to the presence of the protective cover part 4C.
It is possible to effectively prevent damage to the joint boot 4 due to direct application of impact force due to collision of other parts to part A and the main body portion.
なお、前記保護カバ一部４Ｃの寸法は図示の実施例のよ
うに大径開口部４Ａおよびジヨイントブーツの本体部の
一部のみを覆うだけでなく、さらに該ジヨイントブーツ
４の本体部をより広範囲にわたって覆うよう構成するこ
とも可能である。The dimensions of the protective cover portion 4C are such that it not only covers the large diameter opening 4A and a part of the main body of the joint boot 4 as in the illustrated embodiment, but also covers the main body of the joint boot 4. It is also possible to configure it to cover a wider area.
また、前記保護カバ一部４Ｃはジヨイントブーツ４の反
対側の端部等に設けることももちろん可能である。Further, it is of course possible to provide the protective cover portion 4C at the opposite end of the joint boot 4.

ヨイントブーツが損傷されるのを簡単な構造で有効に防
止することができる。As explained above, according to the present invention, a part of the reversible protective cover is integrally formed at the end of the joint boot that covers the opening of the outer member constituting the joint part of the constant velocity joint. The joint boot may be damaged due to other parts colliding with the joint boot when assembling or removing the constant velocity joint from the vehicle, or due to flying stones etc. colliding with the joint boot while the vehicle is running. This can be effectively prevented with a simple structure.
しかも、保護カバ一部をジヨイントブーツに一体形成し
てもジヨイントブーツ自体の構成には何ら変化はなく、
ジヨイントブーツ自体の耐久性等についても何ら悪影響
を及ぼすことはない。Moreover, even if a part of the protective cover is integrally formed with the joint boots, there is no change in the structure of the joint boots themselves.
There is no adverse effect on the durability of the joint boots themselves.
