An appropriate tightening allowance for press-fitting is given to the insertion portion between the stopper piece and the propeller shaft, and the stopper piece is fixed to the propeller shaft.

しかしながら、ストッパピースとプロペラシャフトの挿着部に適度な締め代を与えるためには、プロペラシャフトとストッパピースの両者を適度な寸法精度で加工する必要があり、生産性が悪い。   However, in order to give an appropriate tightening allowance to the insertion portion between the stopper piece and the propeller shaft, it is necessary to process both the propeller shaft and the stopper piece with an appropriate dimensional accuracy, resulting in poor productivity.

本発明の課題は、プロペラシャフト支持構造において、プロペラシャフトとセンタベアリング位置決め用ストッパピースとの挿着部の加工精度を緩和しながら、プロペラシャフトに嵌合したセンタベアリングの抜け止めを図ることにある。   An object of the present invention is to prevent a center bearing fitted to a propeller shaft from coming off while relaxing processing accuracy of an insertion portion between the propeller shaft and a center bearing positioning stopper piece in a propeller shaft support structure. .

請求項１の発明は、環状支持部材の内環内側に、センタベアリングを介してプロペラシャフトを支持するプロペラシャフト支持構造において、センタベアリングの内輪の端面に衝合して該センタベアリングを軸方向に位置決めするストッパピースをプロペラシャフトに挿着し、ストッパピースの前記内輪との衝合端と反対側の端部を軸方向で支持するナットをプロペラシャフトに螺着してなるようにしたものである。   According to the first aspect of the present invention, in the propeller shaft support structure that supports the propeller shaft via the center bearing inside the inner ring of the annular support member, the center bearing abuts on the end face of the inner ring of the center bearing in the axial direction. A stopper piece to be positioned is inserted into the propeller shaft, and a nut that supports the end of the stopper piece opposite to the abutting end with the inner ring in the axial direction is screwed onto the propeller shaft. .

請求項２の発明は、請求項１の発明において更に、前記ナットとストッパピースの間にカバーを挟持し、該カバーが前記内環の開口を覆うフランジを備えるようにしたものである。   According to a second aspect of the present invention, in the first aspect of the present invention, a cover is sandwiched between the nut and the stopper piece, and the cover includes a flange that covers the opening of the inner ring.

請求項３の発明は、請求項１又は２の発明において更に、前記カバーのピース嵌合筒に予めストッパピースを圧入してなるようにしたものである。   According to a third aspect of the present invention, in the first or second aspect of the present invention, a stopper piece is previously press-fitted into the piece fitting cylinder of the cover.

（請求項１）
(a)プロペラシャフトに螺着したナットにより、ストッパピースを軸方向で支持し、ひいてはセンタベアリングを抜け止めする。センタベアリングの抜け止め力が、プロペラシャフトへのストッパピースの圧入保持力に依存するものでないから、プロペラシャフトとストッパピースの挿着部に圧入のための寸法精度を必要としない。従って、プロペラシャフトとストッパピースの挿着部の加工精度を緩和しながら、プロペラシャフトに嵌合したセンタベアリングを抜け止めできる。 (Claim 1)
(a) The stopper piece is supported in the axial direction by a nut screwed onto the propeller shaft, and the center bearing is prevented from coming off.

FIG. 5 is a perspective view showing a cover.

自動車（ＦＲ車又は４ＷＤ車）用衝撃吸収プロペラシャフト１０は、図１に示す如く、前側分割シャフト１０Ａと後側分割シャフト１０Ｂに分割された２本のシャフト部材からなり、両分割シャフト１０Ａ、１０Ｂを等速継手（スライダブルジョイント）１２により連結して構成される。前側分割シャフト１０Ａの前端部は、自在継手１３を介して、エンジン側のトランスミッションの出力軸に接続される連結ヨーク１４と連結され、後側分割シャフト１０Ｂの後端部は、自在継手１５を介して、デファレンシャルギヤに接続される連結ヨーク１６と連結される。   As shown in FIG. 1, an impact absorbing propeller shaft 10 for an automobile (FR vehicle or 4WD vehicle) is composed of two shaft members divided into a front divided shaft 10A and a rear divided shaft 10B, and both divided shafts 10A, 10B. Are connected by a constant velocity joint (slidable joint) 12. The front end portion of the front split shaft 10A is connected to a connecting yoke 14 connected to the output shaft of the engine side transmission via a universal joint 13, and the rear end portion of the rear side split shaft 10B is connected to a universal joint 15. Thus, it is coupled to the coupling yoke 16 connected to the differential gear.

プロペラシャフト１０（シャフト１０Ｂ）は、図２、図３に示す如く、大径部１１Ａから、継手１２が接続される継手部１１Ｅに渡って、外径を階段状に小径化する第１中径部１１Ｂ、第２中径部１１Ｃ、小径部１１Ｄを備える。プロペラシャフト１０は、小径部１１Ｄに嵌合されるセンタベアリング２０を介して環状支持部材３０に回転自在に支持される。   As shown in FIGS. 2 and 3, the propeller shaft 10 (shaft 10B) has a first medium diameter whose outer diameter is reduced stepwise from the large diameter portion 11A to the joint portion 11E to which the joint 12 is connected. A portion 11B, a second medium diameter portion 11C, and a small diameter portion 11D are provided. The propeller shaft 10 is rotatably supported by the annular support member 30 via a center bearing 20 fitted to the small diameter portion 11D.

センタベアリング２０は、ボールベアリングであり、プロペラシャフト１０の小径部１１Ｄに嵌合し、内輪２１の後端面を第２中径部１１Ｃの側面に当接して位置決めされる。   The center bearing 20 is a ball bearing, is fitted to the small diameter portion 11D of the propeller shaft 10, and is positioned by contacting the rear end surface of the inner ring 21 with the side surface of the second medium diameter portion 11C.

環状支持部材３０は、内環３１と外環３２をゴム弾性部材３３を介して接続して構成され、外環３２を支持ブラケット３４に支持される。環状支持部材３０の内環３１は、大径部３１Ａ、中径部３１Ｂ、小径部３１Ｃを順に小径化した段付円筒環をなす。中径部３１Ｂの内側にセンタベアリング２０の外輪２２が嵌合され、大径部３１Ａはプロペラシャフト１０の第１中径部１１Ｂの外周を覆うように後方へ延在し、小径部３１Ｃはプロペラシャフト１０の小径部１１Ｄの外周を覆うように前方へ延在する。   The annular support member 30 is configured by connecting an inner ring 31 and an outer ring 32 via a rubber elastic member 33, and the outer ring 32 is supported by a support bracket 34. The inner ring 31 of the annular support member 30 forms a stepped cylindrical ring in which the large diameter portion 31A, the medium diameter portion 31B, and the small diameter portion 31C are sequentially reduced in diameter. The outer ring 22 of the center bearing 20 is fitted inside the medium diameter part 31B, the large diameter part 31A extends rearward so as to cover the outer periphery of the first medium diameter part 11B of the propeller shaft 10, and the small diameter part 31C is the propeller. The shaft 10 extends forward so as to cover the outer periphery of the small diameter portion 11D of the shaft 10.

プロペラシャフト１０は、環状支持部材３０の内環３１に上述の如くに嵌合されるセンタベアリング２０を介して、回転自在に支持され、センタベアリング２０の前後両側（内環３１の大径部３１Ａと小径部３１Ｃの内周）にはシール部材２３、２４が挿着される。この状態で、センタベアリング２０の内輪２１の前端面に衝合して該センタベアリング２０を軸方向に位置決めするストッパピース４０をプロペラシャフト１０の小径部１１Ｄに挿着し、ストッパピース４０の上記内輪２１との衝合端と反対側の端部を軸方向で位置決め支持するナット６０がプロペラシャフト１０の小径部１１Ｄに設けたねじ部６１に螺着される。このとき、ナット６０とストッパピース４０の間にカバー５０が挟持される。   The propeller shaft 10 is rotatably supported via the center bearing 20 that is fitted to the inner ring 31 of the annular support member 30 as described above, and both front and rear sides of the center bearing 20 (the large diameter portion 31A of the inner ring 31). And sealing members 23 and 24 are inserted into the inner circumference of the small diameter portion 31C. In this state, a stopper piece 40 that abuts the front end surface of the inner ring 21 of the center bearing 20 and positions the center bearing 20 in the axial direction is inserted into the small diameter portion 11D of the propeller shaft 10, and the inner ring of the stopper piece 40 is inserted. A nut 60 for positioning and supporting the end portion opposite to the abutting end with the shaft 21 in the axial direction is screwed to a screw portion 61 provided on the small diameter portion 11D of the propeller shaft 10. At this time, the cover 50 is sandwiched between the nut 60 and the stopper piece 40.

ストッパピース４０は、図３、図４に示す如く、例えば鋼製の円筒状をなす。ストッパピース４０はプロペラシャフト１０の小径部１１Ｄに軽く挿着可能にするように該小径部１１Ｄの外径よりわずかに大きい内径を有する。   The stopper piece 40 has a cylindrical shape made of steel, for example, as shown in FIGS. The stopper piece 40 has an inner diameter slightly larger than the outer diameter of the small diameter portion 11D so that the stopper piece 40 can be lightly inserted into the small diameter portion 11D of the propeller shaft 10.

カバー５０は、図４、図５に示す如く、例えばステンレス又は鋼製の薄板成形品からなり、端板５１、ピース嵌合筒５２、大径フランジ５３を順に大径にした円筒体をなす。   As shown in FIGS. 4 and 5, the cover 50 is made of, for example, a thin plate product made of stainless steel or steel, and forms a cylindrical body in which an end plate 51, a piece fitting cylinder 52, and a large diameter flange 53 are sequentially increased in diameter.

端板５１はプロペラシャフト１０の小径部１１Ｄ（ねじ部６１）まわりに挿着し得るように該小径部１１Ｄのねじ径よりわずかに大きい内径を有する。小径部１１Ｄのねじ部６１に螺着されたナット６０の端面が端板５１に衝接する。   The end plate 51 has an inner diameter slightly larger than the screw diameter of the small diameter portion 11D so that the end plate 51 can be inserted around the small diameter portion 11D (screw portion 61) of the propeller shaft 10. The end surface of the nut 60 screwed to the screw portion 61 of the small diameter portion 11D comes into contact with the end plate 51.

フランジ５３は環状支持部材３０の内環３１の小径部３１Ｃより外径が大きい。カバー５０は、プロペラシャフト１０の小径部１１Ｄに挿着され、ストッパピース４０とナット６０により挟持される状態で、内環３１の前側開口を覆い、泥水浸入防止用フランジを構成する。   The flange 53 has a larger outer diameter than the small diameter portion 31 </ b> C of the inner ring 31 of the annular support member 30. The cover 50 is inserted into the small diameter portion 11D of the propeller shaft 10 and covers the front opening of the inner ring 31 in a state of being sandwiched between the stopper piece 40 and the nut 60, and constitutes a muddy water intrusion prevention flange.

ストッパピース４０とカバー５０は、プロペラシャフト１０の小径部１１Ｄに挿着される前に予め、カバー５０のピース嵌合筒５２の内径部にストッパピース４０の前端部を圧入した小組状態にされる（図３）。ピース嵌合筒５２はストッパピース４０を圧入可能にするように該ストッパピース４０の外径よりわずかに小さい内径を有する。ストッパピース４０の前端面は、上述の圧入状態で、カバー５０のピース嵌合筒５２の底面（端板５１）に衝合する。   The stopper piece 40 and the cover 50 are in a small assembly state in which the front end portion of the stopper piece 40 is press-fitted into the inner diameter portion of the piece fitting cylinder 52 of the cover 50 before being inserted into the small diameter portion 11D of the propeller shaft 10. (Figure 3). The piece fitting cylinder 52 has an inner diameter slightly smaller than the outer diameter of the stopper piece 40 so that the stopper piece 40 can be press-fitted. The front end surface of the stopper piece 40 abuts against the bottom surface (end plate 51) of the piece fitting cylinder 52 of the cover 50 in the above-described press-fitted state.

従って、ストッパピース４０及びカバー５０は以下の如くに用いられる。
(1)小組状態にされたストッパピース４０とカバー５０をプロペラシャフト１０の小径部１１Ｄに軽く挿着する。ストッパピース４０の後端がシール部材２３の内側を貫通してセンタベアリング２０の内輪２１の前端面に当接し、センタベアリング２０を位置決めする。 Therefore, the stopper piece 40 and the cover 50 are used as follows.
(1) The stopper piece 40 and the cover 50 in the small assembly state are lightly inserted into the small diameter portion 11D of the propeller shaft 10. The rear end of the stopper piece 40 penetrates the inside of the seal member 23 and comes into contact with the front end surface of the inner ring 21 of the center bearing 20 to position the center bearing 20.

(2)ナット６０をプロペラシャフト１０の小径部１１Ｄのねじ部６１に螺着し、ナット６０の端面をカバー５０の端板５１に衝接する。これにより、ナット６０はカバー５０を介してストッパピース４０を軸方向で支持し、センタベアリング２０を抜け止めする。このとき、カバー５０のフランジ５３は、環状支持部材３０の内環３１の前側開口を覆う。   (2) The nut 60 is screwed to the screw portion 61 of the small diameter portion 11D of the propeller shaft 10 and the end surface of the nut 60 is brought into contact with the end plate 51 of the cover 50. As a result, the nut 60 supports the stopper piece 40 in the axial direction via the cover 50 and prevents the center bearing 20 from coming off. At this time, the flange 53 of the cover 50 covers the front opening of the inner ring 31 of the annular support member 30.

(3)プロペラシャフト１０に泥水がかかった場合、環状支持部材３０の内環３１の前側開口がカバー５０のフランジ５３に覆われ、この泥水が内環３１内へ浸入することを防止する。   (3) When muddy water is applied to the propeller shaft 10, the front opening of the inner ring 31 of the annular support member 30 is covered with the flange 53 of the cover 50, and this muddy water is prevented from entering the inner ring 31.

尚、内環３１の後側開口は、プロペラシャフト１０の大径部１１Ａで覆われて内環３１内への泥水の浸入が防止されている。仮に大径部１１Ａから浸入した泥水があっても、この泥水は内環３１の大径部３１Ａ内に配置されている第１中径部１１Ｂに設けてある溝条部に直ちに捕捉されて下方へ落下排除され、内環３１内へ浸入することが阻止される。   The rear opening of the inner ring 31 is covered with the large-diameter portion 11A of the propeller shaft 10 to prevent muddy water from entering the inner ring 31. Even if there is muddy water that has entered from the large-diameter portion 11A, this muddy water is immediately captured by the groove portion provided in the first medium-diameter portion 11B disposed in the large-diameter portion 31A of the inner ring 31 and below. And is prevented from entering the inner ring 31.

カバー５０において、フランジ５３に後続する溝条部を設け、この溝条部を内環３１の小径部３１Ｃ内に位置付ければ、プロペラシャフト１０の第１中径部１１Ｂが備える溝条部と同様の泥水落下排除機能を果たす。   In the cover 50, if a groove portion following the flange 53 is provided, and this groove portion is positioned in the small diameter portion 31 </ b> C of the inner ring 31, the groove portion provided in the first medium diameter portion 11 </ b> B of the propeller shaft 10 is the same. Fulfills the function of eliminating mud drops.

環状支持部材３０の内環３１に嵌合されているセンタベアリング２０は、前後をシール部材２３、２４によりシールされる上に、内環３１の前後開口からの泥水浸入を上述の如くに防止され、泥水から確実に保護される。   The center bearing 20 fitted to the inner ring 31 of the annular support member 30 is sealed by the seal members 23 and 24 at the front and rear, and the muddy water is prevented from entering from the front and rear openings of the inner ring 31 as described above. , Reliably protected from muddy water.

本実施例によれば以下の作用効果を奏する。
(a)プロペラシャフト１０に螺着したナット６０により、ストッパピース４０を軸方向で支持し、ひいてはセンタベアリング２０を抜け止めする。センタベアリング２０の抜け止め力が、プロペラシャフト１０へのストッパピース４０の圧入保持力に依存するものでないから、プロペラシャフト１０とストッパピース４０の挿着部に圧入のための寸法精度を必要としない。従って、プロペラシャフト１０とストッパピース４０の挿着部の加工精度を緩和しながら、プロペラシャフト１０に嵌合したセンタベアリング２０を抜け止めできる。 According to the present embodiment, the following operational effects can be obtained.
(a) The stopper piece 40 is supported in the axial direction by the nut 60 screwed to the propeller shaft 10, and the center bearing 20 is prevented from coming off. Since the retaining force of the center bearing 20 does not depend on the press-fitting holding force of the stopper piece 40 to the propeller shaft 10, dimensional accuracy for press-fitting is not required at the insertion portion of the propeller shaft 10 and the stopper piece 40. . Therefore, the center bearing 20 fitted to the propeller shaft 10 can be prevented from coming off while relaxing the processing accuracy of the insertion portion between the propeller shaft 10 and the stopper piece 40.

(b)ストッパピース４０とナット６０の間に挟持したカバー５０のフランジ５３が内環３１の開口を覆い、内環３１の内部、ひいてはセンタベアリング２０への泥水等の浸入を防止し、センタベアリング２０の損傷を防止できる。   (b) The flange 53 of the cover 50 sandwiched between the stopper piece 40 and the nut 60 covers the opening of the inner ring 31 and prevents intrusion of muddy water or the like into the inner ring 31 and thus into the center bearing 20. 20 damage can be prevented.

(c)カバー５０のピース嵌合筒５２に予めストッパピース４０を圧入保持することにより、カバー５０を介してストッパピース４０を軸方向で確実に支持できる。また、カバー５０及びストッパピース４０を小組状態でプロペラシャフト１０に挿着でき、組付性を向上できる。   (c) The stopper piece 40 can be reliably supported in the axial direction via the cover 50 by press-fitting and holding the stopper piece 40 in advance in the piece fitting cylinder 52 of the cover 50. Further, the cover 50 and the stopper piece 40 can be inserted into the propeller shaft 10 in a small assembled state, and the assembling property can be improved.

以上、本発明の実施例を図面により詳述したが、本発明の具体的な構成はこの実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。例えば、カバーとストッパピースは互いに圧入することを必須としない。   The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. It is included in the present invention. For example, it is not essential that the cover and the stopper piece are press-fitted together.

また、本発明の実施においては、プロペラシャフトに螺着したナットによりストッパピースを支持すれば足り、カバーを併せ用いることを必須としない。   In the practice of the present invention, it is sufficient to support the stopper piece with a nut screwed to the propeller shaft, and it is not essential to use a cover together.
