Description

【０００１】
【発明の属する技術分野】
本発明は、車両のプロペラシャフト部分等に用いられる軸継手に関し、とりわけ、軸方向の振動を弾性的に吸収する機能を備えた車両用軸継手に関する。
【０００２】
【従来の技術】
車両のプロペラシャフト部分に用いられる軸継手として、ゴム弾性体を用いたものが知られている（例えば、実開昭６３-１７８６３２号公報参照）。
【０００３】
この軸継手は、図４，図５に示すように、ゴム弾性体から成る略円環状の本体部１に周方向等間隔に複数のブッシュ２が設けられ、隣接するブッシュ２，２相互が剛性の高い補強線材８によって連結されている。第１軸３と第２軸４の各端部には、複数の分岐アーム（結合部）５ａ，６ａを有するヨーク５，６が夫々取付けられ、この両ヨーク５，６の分岐アーム５ａ，６ａが軸継手のブッシュ２に円周方向で交互にボルト１２及びナット１３によって結合されている。そして、第１軸３の先端部は軸継手の本体部１を貫通して突出し、第２軸４にゴムブッシュ７を介してセンタリングされている。
【０００４】
この軸継手の場合、隣接するブッシュ２が補強線材８によって結合されているため、両軸３，４間の軸方向の相対変位は弾性的に許容し、回転方向の動力は補強線材８の張力によって剛的に伝達することができる。
【０００５】
しかし、この従来からある軸継手においては、部品点数が多いうえに装置全体が大型化し易い等の問題があり、近年、これに代わる軸継手として金属プレートを用いたものも開発されている（例えば、実開昭６０−１８９６２０号公報、特開昭６３−３４３２６号公報等参照）。
【０００６】
この軸継手は、図６に示すように、金属製の環状プレート９に円周方向に等間隔にボルト（締結手段）の挿通孔１０…が設けられ、これらの挿通孔１０…に、第１軸側の結合部と第２軸側の結合部（図示は省略してあるが、図４，図５の分岐アーム５ａ，６ａに相当。）が円周方向で交互になるように結合されている。尚、同図中１１は、ボルト締結時に用いられるワッシャである。
【０００７】
したがって、今、環状プレート９上の隣接する挿通孔１０，１０間の領域を連結アーム部９ａと呼ぶとすると、各連結アーム部９ａは、軸方向の振動入力に対し曲げ方向に弾性変形してその振動を吸収することができ、回動方向の入力に対しては変形を生じることなくトルクを剛的に伝達することができる。また、この軸継手の場合、第１軸と第２軸は剛性の高い環状プレート９を介してセンタリングされるため、特別なセンタリング機構を設ける必要もない。
【０００８】
【発明が解決しようとする課題】
この種の軸継手に関しては、現在、曲げ剛性の大幅な増大を招くことなく回転方向の剛性を高めるための手段として、薄肉の環状プレート９を複数枚積層して用いることが考えられている。この場合、曲げ方向の剛性をより低くするためには環状プレート９の一枚当りの肉厚を薄くすることが望ましいが、環状プレート９には第１軸と第２軸の結合部が円周方向に交互に結合され、トルクの伝達時には、隣り合う結合部間で圧縮方向の力が作用する部分と引っ張り方向の力が作用する部分ができるため、環状プレート９の肉厚を薄くすると、引張方向の力が作用する連結アーム部９ａに座屈が生じ易くなる。そして、この座屈はすべての環状プレート９で一定方向に向いて生じれば大きな問題とはならないが、図７に示すように積層されたプレート９，９の連結アーム部９ａ，９ａに相反方向に座屈が生じると、その連結アーム部９ａ，９ａ間に所謂口開き１４が生じ、この口開き１４部分に異物１５が噛み込み、環状プレート９の摩耗の原因となる。
【０００９】
そこで本発明は、積層された環状プレートの相反方向の座屈による環状プレート間への異物の侵入を確実に防止できるようにして、異物の噛み込みによる環状プレートの耐久性の低下を改善することのできる車両用軸継手を提供しようとするものである。
【００１０】
【課題を解決するための手段】
上述した課題を解決するための手段として、請求項１に記載の発明は、第１軸と第２軸の突合せ部に回動方向の剛性の大きい環状プレートを複数枚積層して配置し、前記第１軸と第２軸の各端部に円周方向に間隔をおいて設けられた結合部を、第１軸側のものと第２軸側のものが円周方向で交互になるように、前記環状プレートに締結手段を介して結合し、前記環状プレート上の、締結手段の挿通孔間に位置される連結アーム部の弾性変形により、軸方向の振動を吸収するようにした車両用軸継手において、積層された環状プレートの連結アーム部間の口開きを防止する口開き防止手段を設け、前記口開き防止手段を、積層されるすべての連結アームを予め一定方向に湾曲させておくことによって構成するようにした。
【００１１】
この発明の場合、連結アーム部に作用する圧縮方向の力によって座屈が生じる場合にすべての連結アーム部の座屈方向が同じになり、その結果、トルク伝達時に積層された連結アーム部間に口開きが生じなくなり、その間に異物が噛み込むことがなくなる。
【００１２】
【発明の実施の形態】
次に、本発明の実施形態を図面に基づいて説明する。
【００１３】
まず、図１〜図３に示す本発明の第１の実施形態について説明する。
【００１４】
図３は、本発明にかかる軸継手を適用した車両のプロペラシャフト部分の断面を示すものであり、２０は、変速機側の出力軸、２１は、プロペラシャフトのシャフト本体である。尚、この実施形態においては、この出力軸２０とシャフト本体２１が本発明における第１軸と第２軸を構成している。
【００１５】
出力軸２０側の端部には鋳物製のヨーク２２が結合され、シャフト本体２１側の端部にはプレス成形されたヨーク２３が溶接固定されている。これらのヨーク２２，２３はいずれも三叉状に等間隔に分岐した分岐アーム２２ａ，２３ａを有し、これらの各分岐アーム２２ａ，２３ａの先端が結合部とされている。そして、両ヨーク２２，２３の間には積層した複数枚の金属製の環状プレート２４…が配置され、両ヨーク２２，２３がこれらの環状プレート２４…を介して連結されている。
【００１６】
各環状プレート２４には６つの挿通孔２５が円周方向等間隔に形成されており、出力軸２０側とシャフト本体２１側の各分岐アーム２２ａ，２３ａが、円周方向で交互になるように環状プレート２４…の挿通孔２５部分に締結手段であるボルト２６及びナット２７によって結合されている。この各結合にあたっては、両端の環状プレート２４，２４の外側面に夫々ワッシャ２８，２８が重合配置され、この一対のワッシャ２８，２８で環状プレート２４…を直接挟み込むかたちとなっている。
【００１７】
ここで、各環状プレート２４は、図１に示すようにその外周面が円形状に形成される一方で、内周面が各挿通孔２５の対応位置に頂部を有する六角形状に形成され、隣接する挿通孔２５，２５間の連結アーム部２９には略長方形状の肉抜き孔３０が形成されている。この肉抜き孔３０は、各連結アーム部２９を幅の狭い内側片と外側片とに二分し、それによって各連結アーム部２９の軸方向の曲げ剛性をさらに低減できるようにしたものである。
【００１８】
そして、複数の環状プレート２４…は、挿通孔２５や肉抜き孔３０の位置が合致するようにして積層され、その状態において積層させているすべての環状プレート２４…の連結アーム部２９…を予め一定方向に湾曲させてある。図２において、ａ1，ａ2は、夫々環状プレート２４における湾曲部とフラット部を示すが、湾曲部ａ1は各連結アーム部２９の両端の所定範囲を除く部位に設けられており、ワッシャ２８を介してボルト・ナットの締付力が付与される挿通孔２５の周縁部付近は所定範囲に亙ってフラット部ａ2とされている。
【００１９】
この軸継手は以上のような構成であるため、出力軸２０の駆動トルクはヨーク２２を介して環状プレート２４…に伝達され、さらに環状プレート２４…からヨーク２３を介してシャフト本体２１に伝達される。そして、このとき出力軸２０とシャフト本体２１の間の軸方向の振動は環状プレート２４…の連結アーム部２９の軸方向の曲げ変形によって吸収される。
【００２０】
この軸継手は、環状プレート２４の円周方向に配置された挿通孔２５に対して各ヨーク２２，２３の分岐アーム２２ａ，２３ａが交互に配置されているため、上述のトルクの伝達時には、環状プレート２４上に圧縮方向の力が作用する部分と引っ張り方向の力が作用する部分が交互でき、圧縮方向の力が作用する連結アーム部２９には座屈が生じ易くなる。しかし、このとき駆動トルクの伝達時に連結アーム部２９に圧縮方向の力が作用すると、積層されたすべての連結アーム部２９…は常に予め湾曲して癖付けさせてある一定の方向に座屈を生じる。このため、結束部材を何等付設することなく連結アーム部２９…間の口開きを確実に防止することができる。すべての環状プレート２４…の連結アーム部２９…を予め一定方向に湾曲させたことが、このとき積層された連結アーム部２９…相互の口開きを防止する口開き防止手段として機能する。
【００２１】
したがって、この軸継手においては、すべての環状プレート２４…の連結アーム部２９…を予め一定方向に湾曲させたことによって連結アーム部２９…の口開きを確実に阻止することができるため、この口開きに起因した環状プレート２４…間への異物の噛み込みを防止し、この噛み込みによる環状プレート２４…の摩耗を無くすことができる。
【００２２】
また、異物の噛み込みによる環状プレート２４の耐久性の低下を防止することができるうえ、付設部品の増加による重量の増加や、付設部品の脱落の危惧を無くすことができる。
【００２３】
【発明の効果】
以上のように請求項１に記載の発明は、前記口開き防止手段によってトルク伝達時における積層された連結アーム部間の口開きを無くすことができるため、この口開きに伴う環状プレート間への異物の侵入を確実に防止し、同環状プレートの耐久性を向上させることができる。しかも、積層されるすべての連結アーム部を予め湾曲させておくことによって連結アーム部間の口開きを防止するため、部品点数の増加がないうえに、付設部品の脱落の心配もなく、軽量化や装置の安定作動のうえでも有利となる。

BACKGROUND OF THE INVENTION
The present invention relates to a shaft coupling used for a propeller shaft portion of a vehicle, and more particularly to a vehicle shaft coupling having a function of elastically absorbing axial vibration.
[0002]
[Prior art]
As a shaft coupling used for a propeller shaft portion of a vehicle, one using a rubber elastic body is known (see, for example, Japanese Utility Model Publication No. 63-178632).
[0003]
As shown in FIGS. 4 and 5, the shaft coupling is provided with a plurality of bushes 2 provided at equal intervals in the circumferential direction on a substantially annular main body 1 made of a rubber elastic body, and the adjacent bushes 2, 2 are rigid. Are connected by a high reinforcing wire 8. At each end of the first shaft 3 and the second shaft 4, yokes 5 and 6 having a plurality of branch arms (joining portions) 5a and 6a are respectively attached, and the branch arms 5a and 6a of both yokes 5 and 6 are attached. Are coupled to the bush 2 of the shaft joint alternately by bolts 12 and nuts 13 in the circumferential direction. The distal end portion of the first shaft 3 protrudes through the body portion 1 of the shaft coupling, and is centered on the second shaft 4 via a rubber bush 7.
[0004]
In the case of this shaft coupling, since the adjacent bushes 2 are coupled by the reinforcing wire 8, the relative displacement in the axial direction between the shafts 3 and 4 is elastically allowed, and the rotational power is the tension of the reinforcing wire 8. Can be transmitted rigidly.
[0005]
However, this conventional shaft coupling has problems such as a large number of parts and a large size of the entire device, and recently, a shaft coupling using a metal plate as an alternative to this has been developed (for example, No. 60-189620, JP-A 63-34326, etc.).
[0006]
As shown in FIG. 6, the shaft coupling is provided with insertion holes 10 for bolts (fastening means) at equal intervals in the circumferential direction in a metal annular plate 9, and the first insertion holes 10. The coupling portion on the shaft side and the coupling portion on the second shaft side (not shown, but corresponding to the branch arms 5a and 6a in FIGS. 4 and 5) are coupled so as to alternate in the circumferential direction. Yes. In addition, 11 in the same figure is a washer used at the time of bolt fastening.
[0007]
Accordingly, if the region between the adjacent insertion holes 10 and 10 on the annular plate 9 is called a connecting arm portion 9a, each connecting arm portion 9a is elastically deformed in the bending direction with respect to the axial vibration input. The vibration can be absorbed, and torque can be transmitted rigidly to the input in the rotational direction without causing deformation. In the case of this shaft coupling, since the first shaft and the second shaft are centered via the highly rigid annular plate 9, there is no need to provide a special centering mechanism.
[0008]
[Problems to be solved by the invention]
With regard to this type of shaft coupling, it is currently considered that a plurality of thin annular plates 9 are stacked and used as means for increasing the rigidity in the rotational direction without causing a significant increase in bending rigidity. In this case, in order to further reduce the rigidity in the bending direction, it is desirable to reduce the thickness of each annular plate 9. However, the annular plate 9 has a connection portion between the first shaft and the second shaft on the circumference. When the torque is transmitted, a portion where a force in the compressing direction acts and a portion where a force in the pulling direction acts between adjacent joining portions are formed at the time of torque transmission. Buckling is likely to occur in the connecting arm portion 9a to which a directional force acts. This buckling is not a major problem if it occurs in all the annular plates 9 in a certain direction, but it is in the opposite direction to the connecting arm portions 9a, 9a of the stacked plates 9, 9 as shown in FIG. When buckling occurs, a so-called opening 14 is generated between the connecting arm portions 9 a and 9 a, and the foreign material 15 is caught in the opening 14, causing the annular plate 9 to wear.
[0009]
Therefore, the present invention can reliably prevent the intrusion of foreign matter between the annular plates due to the buckling in the opposite direction of the laminated annular plates and improve the deterioration of the durability of the annular plate due to the biting of the foreign matter. An object of the present invention is to provide a vehicular shaft coupling that can be used.
[0010]
[Means for Solving the Problems]
As a means for solving the above-mentioned problem, the invention according to claim 1 is arranged by laminating a plurality of annular plates having a large rotational rigidity at the butting portion of the first shaft and the second shaft, The coupling portions provided at intervals in the circumferential direction at the end portions of the first axis and the second axis are arranged so that the ones on the first axis side and the second axis side alternate in the circumferential direction. A vehicle shaft that is coupled to the annular plate via fastening means and absorbs vibration in the axial direction by elastic deformation of a connecting arm portion located between the insertion holes of the fastening means on the annular plate. in the joint, set the mouth opening prevention means for preventing the mouth opening between the connecting arm portion of the stacked annular plate only, the port opening prevention means, advance is bent in a certain direction all the connecting arm to be laminated It was configured by
[0011]
In the case of this invention, when the buckling occurs due to the compressive force acting on the connecting arm portion, the buckling direction of all the connecting arm portions becomes the same, and as a result, between the connecting arm portions stacked at the time of torque transmission. Mouth opening does not occur, and foreign objects do not bite in the meantime.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0013]
First, a first embodiment of the present invention shown in FIGS. 1 to 3 will be described.
[0014]
FIG. 3 shows a cross section of a propeller shaft portion of a vehicle to which the shaft coupling according to the present invention is applied. Reference numeral 20 denotes an output shaft on the transmission side, and 21 denotes a shaft main body of the propeller shaft. In this embodiment, the output shaft 20 and the shaft main body 21 constitute the first axis and the second axis in the present invention.
[0015]
A casting yoke 22 is coupled to the end on the output shaft 20 side, and a press-molded yoke 23 is welded to the end on the shaft main body 21 side. Each of these yokes 22 and 23 has branch arms 22a and 23a branched in a trifurcated manner at equal intervals, and the tips of these branch arms 22a and 23a serve as coupling portions. A plurality of laminated metal annular plates 24 are arranged between the yokes 22 and 23, and the yokes 22 and 23 are connected via the annular plates 24.
[0016]
In each annular plate 24, six insertion holes 25 are formed at equal intervals in the circumferential direction, and the branch arms 22a and 23a on the output shaft 20 side and the shaft body 21 side are alternately arranged in the circumferential direction. It connects with the insertion hole 25 part of the cyclic | annular plate 24 ... with the volt | bolt 26 and the nut 27 which are fastening means. In this connection, washers 28, 28 are overlapped on the outer surfaces of the annular plates 24, 24 at both ends, and the annular plates 24 are directly sandwiched between the pair of washers 28, 28.
[0017]
Here, as shown in FIG. 1, each annular plate 24 has an outer peripheral surface formed in a circular shape, while an inner peripheral surface is formed in a hexagonal shape having a top at a corresponding position of each insertion hole 25. In the connecting arm portion 29 between the insertion holes 25, 25, a substantially rectangular hollow hole 30 is formed. The lightening hole 30 divides each connecting arm portion 29 into a narrow inner piece and an outer piece so that the bending rigidity in the axial direction of each connecting arm portion 29 can be further reduced.
[0018]
The plurality of annular plates 24 are stacked so that the positions of the insertion holes 25 and the lightening holes 30 coincide with each other, and the connecting arm portions 29 of all the annular plates 24 that are stacked in that state are provided in advance. Curved in a certain direction. In FIG. 2, a 1 and a 2 indicate a curved portion and a flat portion in the annular plate 24, respectively, but the curved portion a 1 is provided in a portion excluding a predetermined range at both ends of each connecting arm portion 29. The vicinity of the peripheral portion of the insertion hole 25 to which the bolt / nut tightening force is applied via 28 is a flat portion a 2 over a predetermined range.
[0019]
Since the shaft coupling is configured as described above, the drive torque of the output shaft 20 is transmitted to the annular plate 24 through the yoke 22 and further transmitted from the annular plate 24 to the shaft body 21 through the yoke 23. The At this time, the axial vibration between the output shaft 20 and the shaft body 21 is absorbed by the bending deformation in the axial direction of the connecting arm portion 29 of the annular plate 24.
[0020]
In this shaft coupling, the branch arms 22a and 23a of the yokes 22 and 23 are alternately arranged with respect to the insertion holes 25 arranged in the circumferential direction of the annular plate 24. On the plate 24, the portion where the force in the compressing direction acts and the portion where the force in the pulling direction acts can alternate, and the connecting arm portion 29 where the force in the compressing direction acts is likely to buckle. However, if a force in the compression direction acts on the connecting arm portion 29 during transmission of the driving torque at this time, all the stacked connecting arm portions 29... Are always bent in advance and buckled in a certain direction. Arise. For this reason, it is possible to reliably prevent the opening between the connecting arm portions 29... Without attaching any binding member. When the connecting arm portions 29 of all the annular plates 24 are curved in a predetermined direction in advance, the connecting arm portions 29 stacked at this time function as an opening preventing means for preventing mutual opening.
[0021]
Therefore, in this shaft coupling, since the connecting arm portions 29 of all the annular plates 24 are curved in a predetermined direction in advance, the opening of the connecting arm portions 29 can be reliably prevented. It is possible to prevent the foreign plates from being caught between the annular plates 24 due to the opening, and to eliminate the wear of the annular plates 24 caused by this engagement.
[0022]
Further, it is possible to prevent the durability of the annular plate 24 from being deteriorated due to the biting of foreign matter, and it is possible to eliminate the risk of an increase in weight due to an increase in the number of attached parts and a dropout of the attached parts.
[0023]
【The invention's effect】
The invention according to claim 1 as described above, it is possible to eliminate the mouth opening between the stacked connecting arm portion when the torque transmitted by the mouth opening prevention means, to between annular plate associated with the mouth opening Intrusion of foreign matters can be reliably prevented, and the durability of the annular plate can be improved. In addition, since all the connecting arm parts to be laminated are curved in advance to prevent opening between the connecting arm parts, there is no increase in the number of parts, and there is no fear of dropping off the attached parts, thus reducing the weight. It is also advantageous for stable operation of the apparatus.
