Description
【０００１】[0001]
本考案は、軽量化やコストダウンを図った弾性軸継手に関する。 The present invention relates to an elastic shaft coupling that is lightweight and cost-effective.
【０００２】[0002]
従来、図６に示すように、例えば自動車のステアリング用シャフトには、操舵 輪側のシャフト１の端部に固定したヨーク２Ａとハンドル側のシャフト３の端部 に固定したヨーク２Ｂとを、十字ピン４で連結してなる弾性軸継手 (ユニバーサ ルジョイント）５が設けられている (特公昭５７−４５９２５号公報参照）。 Conventionally, as shown in FIG. 6, for example, in a steering shaft of an automobile, a yoke 2A fixed to an end portion of a shaft 1 on a steering wheel side and a yoke 2B fixed to an end portion of a shaft 3 on a steering wheel side are crossed. An elastic shaft joint (universal joint) 5 formed by connecting with a pin 4 is provided (see Japanese Patent Publication No. 57-45925).
【０００３】 この弾性軸継手５は、具体的には、図４及び図５に示すように、一方のヨーク ２Ａの一端側のアーム部２０に十字ピン４用の連結孔２ａ,２ａが形成され、中 間部２１に軸方向の嵌着孔２ｂが形成され、他端側の基部２２に軸直角方向のス トッパー孔２ｃが形成されている。Specifically, as shown in FIGS. 4 and 5, the elastic shaft coupling 5 has connecting holes 2 a, 2 a for the cross pin 4 formed in the arm portion 20 on one end side of one yoke 2 A. An axial fitting hole 2b is formed in the middle portion 21, and a stopper hole 2c extending in the direction perpendicular to the axis is formed in the base portion 22 on the other end side.
【０００４】 上記ヨーク２Ａの嵌着孔２ｂには、弾性部材 (ゴムダンパー）６の外周面に焼 き付けたスリーブ８ａが圧入されて、固定されている。そして、この弾性部材６ の軸芯に形成された挿通孔６ａに焼き付けたスリーブ８ｂに、上記シャフト１の 端部１ａが圧入されて、固定されている。また、ストッパープレート７が、上記 ストッパー孔２ｃと回転方向へ所定の隙間ｔを隔てるように、上記シャフト１の 端部１ａの外周面に形成したセレーションａに係合されて、固定されている。A sleeve 8a baked onto the outer peripheral surface of an elastic member (rubber damper) 6 is press-fitted and fixed in the fitting hole 2b of the yoke 2A. Then, the end portion 1a of the shaft 1 is press-fitted and fixed to the sleeve 8b baked in the insertion hole 6a formed in the shaft center of the elastic member 6. Further, the stopper plate 7 is engaged with and fixed to the serration a formed on the outer peripheral surface of the end 1a of the shaft 1 so as to be separated from the stopper hole 2c by a predetermined gap t in the rotation direction.
【０００５】 そして、ハンドルを回すと、シャフト３からヨーク２Ｂ、十字ピン４、ヨーク ２Ａ、シャフト１の順にトルクが伝達されて、操舵輪が操舵される。When the handle is turned, torque is transmitted from the shaft 3 to the yoke 2B, the cross pin 4, the yoke 2A, and the shaft 1 in this order, and the steered wheels are steered.
【０００６】 上記弾性部材６は、自動車の振動をハンドルに伝わらせないために設けられる もので、自動車の走行中の操舵等のような小トルク伝達時には、その弾力でシャ フト１とヨーク２Ａ間のトルク伝達を行う。また、自動車の停止中の操舵等のよ うな大トルク伝達時には、弾性部材６が弾性変形し、ストッパープレート７がシ ャフト１の軸芯回りに回転して、ヨーク２Ａのストッパー孔２ｃとストッパープ レート７とが係合することによって、シャフト１とヨーク２Ａ間のトルク伝達が 行なわれる。The elastic member 6 is provided to prevent the vibration of the automobile from being transmitted to the steering wheel, and when a small torque is transmitted such as steering during traveling of the automobile, its elastic force causes a force between the shaft 1 and the yoke 2A. Torque transmission. Further, during transmission of a large torque such as steering while the vehicle is stopped, the elastic member 6 elastically deforms, the stopper plate 7 rotates around the shaft center of the shaft 1, and the stopper hole 2c and the stopper hole of the yoke 2A. When the rate 7 is engaged, torque is transmitted between the shaft 1 and the yoke 2A.
【０００７】[0007]
ところで、上記従来の弾性軸継手は、ヨーク２Ａのアーム部２０と基部２２と の間の中間部２１に弾性部材６を嵌着して、固定する構成である。したがって、 必然的に弾性部材６全体をヨーク２Ａ内に収納することになり、弾性部材６の一 部のみをヨーク２Ａ内に収納する場合に比べて、ヨーク２Ａの長さl１が長くな り、重量が増加するという問題がある。 また、シャフト１の端部１Ａの根元にストッパープレート７が固定されるので 、弾性部材６よりもアーム部２０側の端部１aの先端にストッパープレート７を 固定する場合に比べて、弾性部材６の軸方向長さ分だけ、シャフト１の端部１ａ に形成するセレーションａの加工長さl２が長くなり、コストアップになるとい う問題がある。 さらに、十字ピン用の連結孔２aが一端側のアーム部２０に形成され、ストッ パー孔２ｃが他端側の基部２２に形成されて、連結孔２aとストッパー孔２cとが 弾性部材６の軸方向両側に配置されているので、ストッパー孔２cの位置と十字 ピン４用の連結孔２ａの位置とが離隔し、大トルク伝達時に、ヨーク２Ａのねじ れ剛性が不足して操舵フィーリングが悪くなるという問題がある。 By the way, the above-mentioned conventional elastic shaft coupling is configured such that the elastic member 6 is fitted and fixed to the intermediate portion 21 between the arm portion 20 and the base portion 22 of the yoke 2A. Therefore, the entire elastic member 6 is inevitably housed in the yoke 2A, and the length l1 of the yoke 2A becomes longer than in the case where only a part of the elastic member 6 is housed in the yoke 2A. There is a problem that the weight increases. Further, since the stopper plate 7 is fixed to the base of the end portion 1A of the shaft 1, the elastic member 6 is different from the case where the stopper plate 7 is fixed to the tip of the end portion 1a closer to the arm 20 than the elastic member 6. The machining length l2 of the serration a formed on the end 1a of the shaft 1 is increased by the axial length of the above, and there is a problem that the cost is increased. Further, a connecting hole 2a for the cross pin is formed in the arm portion 20 on one end side, a stopper hole 2c is formed in the base portion 22 on the other end side, and the connecting hole 2a and the stopper hole 2c are formed in the shaft of the elastic member 6. Since they are arranged on both sides in the direction, the position of the stopper hole 2c is separated from the position of the connecting hole 2a for the cross pin 4, and when the large torque is transmitted, the torsional rigidity of the yoke 2A is insufficient and the steering feeling is bad. There is a problem of becoming.
【０００８】 そこで、本考案の目的は、軽量化やコストダウンおよび操舵フィーリングの向 上を図った弾性軸継手を提供することにある。[0008] Therefore, an object of the present invention is to provide an elastic shaft coupling that is lighter in weight, lower in cost, and improved in steering feeling.
【０００９】[0009]
上記目的を達成するため、本考案は、一端側のアーム部に十字ピン用の連結孔 を有し、中間部にストッパー係合部を有し、他端側の基部に軸方向の嵌着孔を有 するヨークと、軸芯に挿通孔を有し、上記ヨークの嵌着孔に嵌合されて外周面の 少なくとも一部が上記ヨークに固定される弾性部材と、この弾性部材の挿通孔に 挿通されて上記弾性部材に固定される軸部材と、この軸部材の先端に設けられ、 上記ヨークのストッパー係合部と回転方向へ所定の隙間を隔てると共に、軸芯回 りに回転したときに上記ストッパー係合部に係合するストッパーとを備えたこと を特徴としている。 In order to achieve the above object, the present invention has a connecting hole for a cross pin on an arm portion on one end side, a stopper engaging portion on an intermediate portion, and an axial fitting hole on a base portion on the other end side. And an elastic member that has an insertion hole in the shaft core, is fitted in the fitting hole of the yoke, and at least a part of the outer peripheral surface is fixed to the yoke, and the insertion hole of the elastic member. A shaft member which is inserted and fixed to the elastic member, and which is provided at the tip of the shaft member, separates a predetermined gap in the rotation direction from the stopper engaging portion of the yoke, and when rotating around the shaft core. And a stopper that engages with the stopper engaging portion.
【００１０】[0010]
上記構成によれば、他端側の基部に設けた嵌着孔に、弾性部材の一部または全 部が嵌合されて、固定される。したがって、上記嵌着孔に上記弾性部材の一部の みを嵌合させる構成にすれば、弾性部材の全部をヨークに嵌合させる場合に比べ て、ヨークの長さを短縮できて、ヨークが軽量化する。 また、軸部材の先端にストッパーを設けたので、軸部材にストッパーをセレー ション嵌合させる場合、軸部材の先端に設けた弾性部材よりも根元側にストッパ ーを設けた従来例よりも、軸部材に形成するセレーションの加工長さを短縮でき 、加工コストが安くなる。 さらに、中間部にストッパー係合部を有し、一端側のアーム部に十字ピン用の 連結孔を有するので、上記ストッパー係合部と連結孔の両方が、上記弾性部材の 軸方向の片側に配置される。したがって、本考案によれば、弾性部材を軸方向両 側から挟む位置にストッパー孔と連結孔を形成した従来例に比べて、ストッパー 係合部の位置と十字ピン用の連結孔の位置との間の距離を短縮でき、大トルク伝 達時のねじれ剛性が高まって、操舵フィーリングが向上する。 According to the above configuration, a part or all of the elastic member is fitted and fixed in the fitting hole provided in the base portion on the other end side. Therefore, if only a part of the elastic member is fitted into the fitting hole, the length of the yoke can be shortened as compared with the case where the entire elastic member is fitted to the yoke, and the yoke is Reduce weight. In addition, since the stopper is provided at the tip of the shaft member, when fitting the stopper to the shaft member in serration, the shaft is provided with a stopper that is closer to the root side than the elastic member provided at the tip of the shaft member. The processing length of the serration formed on the member can be shortened and the processing cost can be reduced. Furthermore, since the intermediate portion has a stopper engaging portion and the arm portion at one end has a connecting hole for a cross pin, both the stopper engaging portion and the connecting hole are provided on one side in the axial direction of the elastic member. Will be placed. Therefore, according to the present invention, the position of the stopper engaging portion and the position of the connecting hole for the cross pin are different from those of the conventional example in which the stopper hole and the connecting hole are formed at positions where the elastic member is sandwiched from both sides in the axial direction. The distance between them can be shortened, and the torsional rigidity at the time of transmitting a large torque is increased, improving the steering feeling.
【００１１】[0011]
以下、本考案を図示の実施例により詳細に説明する。 図１及び図２に示すように、この実施例の弾性軸継手は、ヨーク１０と、弾性 部材１１と、シャフト (軸部材）１２と、ストッパープレート１３とで基本構成 される。 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. As shown in FIGS. 1 and 2, the elastic shaft coupling of this embodiment is basically composed of a yoke 10, an elastic member 11, a shaft (shaft member) 12, and a stopper plate 13.
【００１２】 上記ヨーク１０には、一端側のフォーク状のアーム部１００に十字ピン (図示 しない。）用の連結孔１０ａ,１０ａが形成され、中間部１０１にストッパー係 合部としてのストッパー用切り欠き部１０ｂ,１０ｂ(図２参照)が形成され、他 端側の基部１０２に軸方向の嵌着孔１０ｃが形成されている。この嵌着孔１０ｃ の深さl３は、上記弾性部材１１の軸方向長さの約１／２に設定されている。な お、嵌着孔１０ｃの深さを弾性部材１１の軸方向長さと同じに設定しても良い。In the yoke 10, connecting holes 10 a and 10 a for cross pins (not shown) are formed in a fork-shaped arm portion 100 on one end side, and a stopper cutting portion serving as a stopper engaging portion is formed in the intermediate portion 101. Notches 10b, 10b (see FIG. 2) are formed, and an axial fitting hole 10c is formed in the base portion 102 on the other end side. The depth l3 of the fitting hole 10c is set to about 1/2 of the axial length of the elastic member 11. The depth of the fitting hole 10c may be set to be the same as the axial length of the elastic member 11.
【００１３】 上記弾性部材１１は、円筒状のゴムダンパーであり、外周面および軸芯の挿通 孔１１ａにはスリーブ１４ａおよび１４ｂが焼付けられている。The elastic member 11 is a cylindrical rubber damper, and sleeves 14a and 14b are baked on the outer peripheral surface and the insertion hole 11a of the shaft core.
【００１４】 上記シャフト１２は、操舵側またはハンドル側のいずれか一方側のシャフトで あり、先端の小径部１２ａにはセレーションａが形成されている。The shaft 12 is a shaft on either the steering side or the steering wheel side, and the serration a is formed on the small diameter portion 12a at the tip.
【００１５】 上記弾性部材１１の外周面に焼き付けられたスリーブ１４ａは上記ヨーク１０ の嵌着孔１０ｃに圧入されて固定され、上記スリーブ１４ｂは上記シャフト１２ に圧入されて固定される。なお、弾性部材１１にスリーブ１４ａ,１４ｂを焼き 付けずに、弾性部材１１の外周面および挿通孔１１ａを、ヨーク１０の嵌着孔１ ０ｃおよびシャフト１２に直接に焼付けても良い。The sleeve 14 a baked on the outer peripheral surface of the elastic member 11 is press-fitted and fixed in the fitting hole 10 c of the yoke 10, and the sleeve 14 b is press-fitted and fixed in the shaft 12. The outer peripheral surface of the elastic member 11 and the insertion hole 11a may be directly baked on the fitting hole 10c of the yoke 10 and the shaft 12 without baking the sleeves 14a and 14b on the elastic member 11.
【００１６】 上記ストッパープレート１３は、略Ｉ字状に形成されていて、中央孔１３ａが 上記シャフト１２の小径部１２ａのセレーションａに係合し固定されている。ま た、図２に示すように、ストッパープレート１３の先端部１３ｂ,１３ｂは、上 記ヨーク１０のストッパー用切り欠き部１０ｂ,１０ｂと回転方向へ所定の隙間 ｔを隔てている。 なお、図３に示すように、ストッパープレート１３は、シャフト１２の先端に 一体的に設けても良い。また、ストッパープレート１３とシャフト１２とはセレ ーション係合固定構造ではなく、小判形状の係合固定構造でも、溶接固定構造で も良い。The stopper plate 13 is formed in a substantially I shape, and the central hole 13 a is engaged and fixed to the serration a of the small diameter portion 12 a of the shaft 12. Further, as shown in FIG. 2, the tip portions 13b, 13b of the stopper plate 13 are separated from the stopper notches 10b, 10b of the yoke 10 in the rotation direction by a predetermined gap t. Note that, as shown in FIG. 3, the stopper plate 13 may be integrally provided at the tip of the shaft 12. Further, the stopper plate 13 and the shaft 12 may have an oval-shaped engagement fixing structure or a welding fixing structure instead of the selection engagement fixing structure.
【００１７】 この実施例の弾性軸継手は、小トルク伝達時には、弾性部材１１の弾力でシャ フト１２とヨーク１０間のトルク伝達を行い、大トルク伝達時には弾性部材１１ の弾性変形によって軸芯回りに回転したストッパープレート１３とストッパー切 り欠き部１０ｂとが係合して、シャフト１２とヨーク１０間のトルク伝達を行う 。 上記実施例によれば、基部１０２に、弾性部材１１の一部だけを嵌合させる嵌 着孔１０ｃを形成することにより、弾性部材の全体をヨークに嵌合させる従来例 のヨーク長l１よりも短いヨーク長l４に、ヨーク１０の長さを短縮でき、ヨーク １０を軽量化できる。The elastic shaft coupling of this embodiment transmits torque between the shaft 12 and the yoke 10 by the elastic force of the elastic member 11 when transmitting a small torque, and elastically deforms the elastic member 11 when transmitting a large torque to rotate the shaft center. The stopper plate 13 rotated to the left and the stopper notch 10b are engaged with each other to transmit torque between the shaft 12 and the yoke 10. According to the above-described embodiment, by forming the fitting hole 10c in which only a part of the elastic member 11 is fitted in the base portion 102, the yoke length l1 of the conventional example in which the entire elastic member is fitted in the yoke is formed. The length of the yoke 10 can be shortened to the short yoke length l4, and the weight of the yoke 10 can be reduced.
【００１８】 また、大トルク伝達時に軸芯回りに回転して、ヨーク１０の中間部１０１のス トッパー用切り欠き部１０ｂに係合するストッパープレート１３をシャフト１２ の先端に固定するので、シャフト１２の小径部１２ａのセレーションａの加工長 さを、軸部材の先端に設けた弾性部材よりも根元側にストッパープレートを設け た従来例のセレーション長さl２よりも短いl５に短縮でき、加工コストを安くで きる。Further, when the large torque is transmitted, the stopper plate 13 that rotates around the axis and engages with the notch portion 10b for the stopper of the intermediate portion 101 of the yoke 10 is fixed to the tip of the shaft 12. The processing length of the serration a of the small diameter part 12a can be shortened to l5 which is shorter than the serration length l2 of the conventional example in which the stopper plate is provided on the base side of the elastic member provided at the tip of the shaft member, and the processing cost is reduced. It can be cheap.
【００１９】 さらに、中間部１０１にストッパー係合部としてのストッパー用切り欠き部１ ０bを有し、一端側のアーム部１００に十字ピン用の連結孔１０aを有するので、 上記切り欠き部１０bと連結孔１０aの両方が弾性部材１１の軸方向の片側に配置 される。したがって、上記実施例によれば、弾性部材を軸方向両側から挟む位置 にストッパー孔と連結孔を形成した従来例に比べて、ストッパー係合部の位置と 十字ピン用の連結孔１０aの位置との間の距離を短縮でき、大トルク伝達時のね じれ剛性が向上し、操舵フィーリングを向上できる。Further, since the intermediate portion 101 has a stopper notch portion 10b as a stopper engaging portion, and the arm portion 100 on one end side has a connecting hole 10a for a cross pin, the notch portion 10b Both of the connecting holes 10a are arranged on one side of the elastic member 11 in the axial direction. Therefore, according to the above-described embodiment, the position of the stopper engaging portion and the position of the connecting hole 10a for the cross pin are different from those of the conventional example in which the stopper hole and the connecting hole are formed at the positions sandwiching the elastic member from both sides in the axial direction. The distance between them can be shortened, the torsional rigidity at the time of transmitting a large torque is improved, and the steering feeling can be improved.
【００２０】[0020]
以上の説明からも明らかなように、本考案の弾性軸継手は、ヨークの中間部に 設けたストッパー係合部に、軸部材の先端に設けたストッパーを係合させ、基部 の嵌着孔に弾性部材の一部または全部を嵌合させて固定するようにしたものであ る。 したがって、上記嵌着孔に弾性部材の一部のみを嵌合し固定する構成が可能に なり、弾性部材の全体をヨークに嵌合させた従来例に比べて、ヨークの長さを短 縮でき、ヨークを軽量化できるようになる。 また、軸部材の先端にストッパーを設けたので、軸部材にストッパーをセレー ション嵌合させる場合、軸部材へのセレーション加工の長さを最短にでき、加工 コストを安くできる。 さらに、上記ストッパー係合部と連結孔の両方が、上記弾性部材の軸方向の片 側に配置されるので、弾性部材を軸方向両側から挟む位置にストッパー孔と連結 孔を形成した従来例に比べて、ストッパー係合部の位置と十字ピン用の連結孔の 位置との距離を短縮でき、大トルク伝達時のねじれ剛性が高まって、操舵フィー リングが向上する。 As is clear from the above description, in the elastic shaft coupling of the present invention, the stopper provided at the tip of the shaft member is engaged with the stopper engaging portion provided at the middle portion of the yoke, so that the fitting hole at the base portion is fitted. A part or all of the elastic member is fitted and fixed. Therefore, it is possible to fit and fix only a part of the elastic member in the fitting hole, and the length of the yoke can be shortened compared to the conventional example in which the entire elastic member is fitted to the yoke. The weight of the yoke can be reduced. Further, since the stopper is provided at the tip of the shaft member, when the stopper is serration-fitted to the shaft member, the length of serration processing on the shaft member can be minimized, and the processing cost can be reduced. Further, since both the stopper engaging portion and the connecting hole are arranged on one side of the elastic member in the axial direction, the stopper hole and the connecting hole are formed at positions sandwiching the elastic member from both sides in the axial direction. In comparison, the distance between the position of the stopper engaging portion and the position of the connecting hole for the cross pin can be shortened, the torsional rigidity at the time of transmitting a large torque is increased, and the steering feeling is improved.
