本考案は歯車変速機の同期噛合装置に用いるシンクロナイザリングに関する。 The present invention relates to a synchronizer ring used for a synchronous meshing device of a gear transmission.
【０００２】[0002]
従来歯車変速機の同期噛合装置に用いられるシンクロナイザリングにおいて、 第３図に示すように、シンクロナイザリング本体１の円錐状内周面１ａに、円周 方向に刻設したねじ状連続溝２と該ねじ状連続溝を欠除するための溝３とを形成 すると共に該溝３の溝幅ｗ1 を、円錐状内周面１ａの小径側と大径側とが同一幅 になるように形成したものが実開昭４８−３８２４８号公報、実開昭５５−９２ ９２０号公報に開示されている。In a conventional synchronizer ring used for a synchronous meshing device of a gear transmission, as shown in FIG. 3, a conical inner peripheral surface 1a of a synchronizer ring main body 1 is provided with a threaded continuous groove 2 formed in a circumferential direction and A groove 3 for removing the threaded continuous groove is formed, and the groove width w 1 of the groove 3 is formed so that the small diameter side and the large diameter side of the conical inner peripheral surface 1a have the same width. Those are disclosed in Japanese Utility Model Publication No. 48-38248 and Japanese Utility Model Publication 55-92920.
【０００３】 しかし該溝３をこのように同一幅に形成すると、歯車側円錐体と接触する円錐 状円周面１ａの接触面積が小径側の方が大径側より狭くなるので、単位面積当た りの面圧は小径側の方が大径側より大きくなる。ところで、変速時においては、 歯車側円錐体とシンクロナイザリングの円錐状内周面が摩擦係合する初期に、シ ンクロナイザリングの円錐状内周面における小径側が歯車側円錐体に大径側より 先行して接触して、小径側に局所的な高荷重が作用することが知られている。However, when the grooves 3 are formed to have the same width in this way, the contact area of the conical circumferential surface 1a that contacts the gear side cone becomes smaller on the small diameter side than on the large diameter side, so that the unit area The surface pressure is higher on the small diameter side than on the large diameter side. By the way, during gear shifting, the smaller diameter side of the conical inner peripheral surface of the synchronizer ring is larger than the larger diameter side of the conical inner peripheral surface of the synchronizer ring at the initial stage of frictional engagement between the gear side conical body and the conical inner peripheral surface of the synchronizer ring. It is known that they come into contact in advance and a local high load acts on the small diameter side.
【０００４】 そのため、前記のように小径側の単位面積当たりの面圧が大きいと変速時に歯 車側円錐体へのシンクロナイザリングの食いつき現象が発生し、シフトフィーリ ングの悪化を招来する問題がある。そのため、本願人はさきに、シンクロナイザ リングの円錐状内周面の歯車側円錐体に対する接触面積を小径側＞大径側として 面圧が大径側＞小径側とするためにシンクロナイザリングの円錐状内周面に、そ の軸方向に延び、かつ大径側より小径側の方の幅が広い台形状の突起部を数個均 等間隔をもって配置したものを提案した（実公昭６２−４６９１０）。Therefore, as described above, when the surface pressure per unit area on the small diameter side is large, there is a problem that the synchronizer ring bites into the toothed cone during gear shifting, which causes deterioration of shift feeling. . Therefore, the applicant first noted that the contact area of the conical inner peripheral surface of the synchronizer ring with respect to the cone on the gear side is the smaller diameter side> the larger diameter side, and the contact pressure is the larger diameter side> the smaller diameter side. A proposal was made in which several trapezoidal protrusions that extend in the axial direction and that are wider on the small diameter side than on the large diameter side are arranged at equal intervals on the inner peripheral surface (Actual Publication 62-46910). .

【考案が解決しようとする課題】 ところが上記突起部を形成したものにおいては次のような欠点を招来する。 すなわち突起部で形成される接触面にねじ状連続溝が切てないことによりオイ ルの排出力が悪く油膜切れがない。従って結合当初の食いつきは防止できるとし ても、結合部でのオイルの排出力が悪く油膜によるスリップが招来する欠点があ る。[Problems to be Solved by the Invention] However, the following drawbacks are caused in the case where the above-mentioned protrusion is formed. That is, since the screw-shaped continuous groove is not cut on the contact surface formed by the protrusion, the oil discharge force is poor and the oil film is not broken. Therefore, even if the bite at the beginning of the coupling can be prevented, there is a drawback that the oil drainage force at the coupling part is poor and slip due to the oil film is caused.
【０００６】 本案はこの欠点を一掃することを目的とする。The present invention aims to eliminate this drawback.

本考案は前記の目的を達成するために、歯車変速機の同期噛合装置における歯 車側円錐体５ａと対応する円錐状内周面６ａを有し、該円錐状内周面に、その周 方向にねじ状連続溝６ｅを刻設すると共に該ねじ状連続溝を欠除するための軸方 向に延びる溝を形成したシンクロナイザリングにおいて、前記ねじ状連続溝６ｅ を欠除するめたの溝をシンクロナイザリング６の大径側を広く小径側に逓減させ て形成し、シンクロナイザリングの円錐状内周面すなわち歯車側円錐体に対する 接触面をねじ状連続溝で、しかも接触面積を小径側＞大径側に形成したことを特 徴とするものである。 In order to achieve the above-mentioned object, the present invention has a conical inner peripheral surface 6a corresponding to a toothed wheel side cone 5a in a synchronous meshing device of a gear transmission, and the conical inner peripheral surface has a circumferential direction. In a synchronizer ring in which a thread-like continuous groove 6e is engraved and an axially extending groove is formed for removing the thread-like continuous groove, a groove for removing the thread-like continuous groove 6e is provided in the synchronizer ring. The ring 6 is formed by gradually reducing the larger diameter side to the smaller diameter side, and the conical inner peripheral surface of the synchronizer ring, that is, the contact surface for the gear side cone is a threaded continuous groove, and the contact area is the smaller diameter side> the larger diameter side. It is characterized by being formed in

次に本考案のシンクロナイザリングを用いる同期噛合装置の概要を第２図によ り説明する。 Next, the outline of the synchronous meshing device using the synchronizer ring of the present invention will be explained with reference to FIG.
【０００９】 ４は主軸でこれに変速歯車５が回転自在に嵌合され、その歯車側円錐体５ａに 対してシンクロナイザリング６が係合するように設置されている。 ７は主軸４に固着されているハブ、８は該ハブ７に対して軸方向に摺動可能に スプライン嵌合されているハブスリーブで、変速時に軸方向に摺動し、これによ り、まずハブ７とハブスリーブ８との間にキースプリング９で保持されているキ ー１０が、ハブスリーブ８に押されて軸方向に移動してシンクロナイザリング６ のキー溝６ａに当たり、シンクロナイザリング６の円錐状内周面６ｂを歯車円錐 体５ａに押し当て、更にハブスリーブ８が一層軸方向に移動されると、シンクロ ナイザリング６の外周部の複数のスプライン歯６ｃを押しつけると同時にシンク ロナイザリング６の円錐状内周面６ｂを歯車側円錐体５ａに一層押しつける。Reference numeral 4 denotes a main shaft, to which a speed change gear 5 is rotatably fitted, and is installed so that a synchronizer ring 6 is engaged with a gear side cone 5 a thereof. Reference numeral 7 is a hub fixed to the main shaft 4, 8 is a hub sleeve spline-fitted to the hub 7 so as to be slidable in the axial direction. First, the key 10 held by the key spring 9 between the hub 7 and the hub sleeve 8 is pushed by the hub sleeve 8 and moves in the axial direction to come into contact with the key groove 6a of the synchronizer ring 6, and the synchronizer ring 6 When the conical inner peripheral surface 6b is pressed against the gear cone 5a and the hub sleeve 8 is further moved in the axial direction, the plurality of spline teeth 6c on the outer peripheral portion of the synchronizer ring 6 are pressed and at the same time the cone of the synchronizer ring 6 is pressed. The inner peripheral surface 6b is further pressed against the gear side cone 5a.
【００１０】 そのために、主軸４の回転力がハブ７及びシンクロナイザリング６を介して変 速歯車５に伝達され、変速歯車５の回転速度が主軸４の回転速度と同期される。 そしてこの状態で変速歯車５が係合される。Therefore, the rotational force of the main shaft 4 is transmitted to the variable speed gear 5 via the hub 7 and the synchronizer ring 6, and the rotational speed of the speed change gear 5 is synchronized with the rotational speed of the main shaft 4. Then, the transmission gear 5 is engaged in this state.
【００１１】 次に本考案のシンクロナイザリングについて第１図により詳述する。 該シンクロナイザリング６における環状の主体部６ｄの外周部には複数のスプ ライン歯６ｃが突設され、また内周には前記歯車側円錐体５ａの円錐面に対応す る円錐面に形成された円錐状内周面６ｂが形成されている。該円錐状内周面６ｂ には周方向に刻設したねじ状連続溝６ｅを有し、かつ軸方向に沿う溝６ｆが円周 方向に対して等間隔又は不等間隔に複数本形成されている。該軸方向に沿う溝６ ｆにおける円周方向の溝幅は、円錐状内周面６ｂにおける大径側の溝幅Ｗ3 より 小径側の溝幅Ｗ2 の方が狭くなるように形成されており、歯車側円錐体５ａとシ ンクロナイザリング６とが摩擦係合する際の接触面積が大径側より小径側の方が 広くなるように設定されている。尚、ねじ状連続溝を欠除するための溝６ｆは、 内周面６ｂの小径側端面まで貫通させなくともよく、また軸方向全長に亘る同一 幅でかつ円周面６ｂの大径側部のみに設けてもよい。Next, the synchronizer ring of the present invention will be described in detail with reference to FIG. A plurality of spline teeth 6c are projectingly provided on the outer peripheral portion of the annular main body portion 6d of the synchronizer ring 6, and the inner peripheral surface is formed into a conical surface corresponding to the conical surface of the gear side conical body 5a. A conical inner peripheral surface 6b is formed. The conical inner peripheral surface 6b has a thread-like continuous groove 6e engraved in the circumferential direction, and a plurality of grooves 6f extending along the axial direction are formed at equal or unequal intervals in the circumferential direction. There is. Circumferential groove width of the groove 6 f along the axial direction is formed so as than the width W 3 of the large-diameter side of the conical inner circumferential surface 6b is towards the groove width W 2 of the small diameter side becomes narrow The contact area when the gear-side cone 5a and the synchronizer ring 6 are frictionally engaged is set to be wider on the small diameter side than on the large diameter side. The groove 6f for eliminating the threaded continuous groove does not have to penetrate to the end surface on the small diameter side of the inner peripheral surface 6b, and has the same width over the entire axial length and the large diameter side portion of the circumferential surface 6b. You may provide only in.

以上のように本考案は、シンクロナイザリング６の円錐状内周面６ｂに、円周 方向に刻設されたねじ状連続溝６ｅを欠除させる溝６ｆを、歯車側円錐体５ａと ねじ状連続溝６ｅとが摩擦係合する際の接触面積を、大径側より小径側の方が広 くなるように形成したから、単位面積当たりの面圧が大径側より小径側の方が小 さくなり、したがって、変速時における歯車側円錐体５ａとシンクロナイザリン グ６の円錐状内周面６ｂとが摩擦係合する初期において、シンクロナイザリング ６の円錐状内周面６ｂの小径側が歯車側円錐体５ａに局所的に高荷重で押し当て られた場合にも、歯車側円錐体５ａへのシンクロナイザリング６の食い付き現象 が発生せず、対応する歯車側円錐体５ａを円滑に摺動し、ハブスリーブ８の摺動 を阻止することがない。そのためシフトフィーリングが良好になる特徴がある。 As described above, according to the present invention, the conical inner peripheral surface 6b of the synchronizer ring 6 is provided with the groove 6f for cutting out the thread-shaped continuous groove 6e engraved in the circumferential direction, and the groove-side conical body 5a and the thread-shaped continuous body 6a. Since the contact area when frictionally engaging with the groove 6e is wider on the small diameter side than on the large diameter side, the surface pressure per unit area is smaller on the small diameter side than on the large diameter side. Therefore, in the initial stage of frictional engagement between the gear side cone 5a and the conical inner peripheral surface 6b of the synchronizer ring 6 during gear shifting, the smaller diameter side of the conical inner peripheral surface 6b of the synchronizer ring 6 is the gear side cone. Even if it is locally pressed against a gear 5a with a high load, the phenomenon that the synchronizer ring 6 bites the gear-side cone 5a does not occur, and the corresponding gear-side cone 5a slides smoothly and the hub Preventing sliding of sleeve 8 No. Therefore, there is a characteristic that the shift feeling is improved.
