Description

この発明は、自動変速機の後方側に、減衰手段および動力分配手段を具えるトランスファ機構を配設してなる自動変速機のアウトプット構造に関するものであり、とくには、構造体の全長を低減させて搭載性を有利に向上させた技術を提案するものである。   The present invention relates to an output structure of an automatic transmission in which a transfer mechanism including a damping means and a power distribution means is disposed on the rear side of the automatic transmission, and in particular, to reduce the overall length of the structure. Thus, a technology that advantageously improves the mountability is proposed.

自動変速機の後方側に、減速手段および動力分配手段を具えるトランスファ機構を配設する場合、図９に縦断面図で例示するように、自動変速機１１１の入力軸１１２と同一の軸線上に変速機出力軸１１３を配置するとともに、自動変速機１１１とは別体構造となるトランスファ機構部１１４においてもまた入力軸１１５と同一の軸線上に、たとえば後輪用の出力軸１１６を配置し、そして、これらの両者１１１，１１４の入出力軸１１２，１１３と、１１５，１１６とを、それらのそれぞれのケース１１７，１１８を繋ぐアダプタケース１１９内で相互に同芯に連結する構造を採用することが行われている。   When a transfer mechanism including a speed reduction unit and a power distribution unit is disposed on the rear side of the automatic transmission, as illustrated in a longitudinal sectional view in FIG. 9, the same axis as the input shaft 112 of the automatic transmission 111 is used. The transmission output shaft 113 is disposed at the same time, and the transfer mechanism 114, which is a separate structure from the automatic transmission 111, is also disposed on the same axis as the input shaft 115, for example, an output shaft 116 for rear wheels. And the structure which connects the input / output shafts 112 and 113 of these both 111 and 114, 115, 116 mutually concentrically within the adapter case 119 which connects those cases 117 and 118 is employ | adopted. Things have been done.

しかるに、この従来技術では、自動変速機１１１と、アダプタケース１１９と、トランスファ機構部１１４とを直列に整列配置させて、アダプタケース１１９を単なる連結部として機能させていることから、構造体の全長が長くなりすぎて、その構造体の搭載が、長さ寸法上の制約を受けることがしばしばあるという搭載性に関する問題があった。   However, in this prior art, the automatic transmission 111, the adapter case 119, and the transfer mechanism 114 are aligned and arranged in series so that the adapter case 119 functions as a mere connecting portion. However, the mounting of the structure is often restricted by the length dimension, and there is a problem regarding mounting properties.

この発明は、従来技術が抱えるこのような問題点を解決することを課題とするものであり、それの目的とするところは、自動変速機およびトランスファ機構を具えるとともに、それらのそれぞれのケースを繋ぐアダプタケースを具える構造体の全長を十分短くして、その構造体の搭載性を大きく向上させた、自動変速機のアウトプット構造を提供するにある。   The present invention has an object to solve such problems of the prior art, and an object of the present invention is to provide an automatic transmission and a transfer mechanism, and to provide respective cases for them. It is an object of the present invention to provide an output structure for an automatic transmission in which the length of the structure including the adapter case to be connected is sufficiently shortened to greatly improve the mountability of the structure.

この発明の、自動変速機のアウトプット構造は、自動変速機の後方側に、減速手段および動力分配手段を具えるトランスファ機構を配設してなるものであって、自動変速機の変速本体ケースの後方側にアダプタケースを直列的に連結し、このアダプタケース内に、自動変速機の出力軸上にスプライン嵌合、ねじ固定等によって組付けたアウトプットギアを含む減速手段を収納配置するとともに、変速機本体ケースとアダプタケースとに跨がらせて、前記減速手段からの出力を、たとえば前輪側へ所要に応じた割合で、自動変速機の入力軸側に向く出力軸をもって取り出す動力分配手段を配設し、その減速手段を構成するギアの一枚以上をアダプタケースとの協働下で位置決め支持する中間壁を、アダプタケース内に、ボルト等によって固定配置してなるものである。また、アダプタケース内で、変速機本体ケースと中間壁との間にパーキングギアを配設する。 The output structure of the automatic transmission according to the present invention is such that a transfer mechanism including a speed reduction means and a power distribution means is disposed on the rear side of the automatic transmission, and a transmission main body case of the automatic transmission is provided. The adapter case is connected in series to the rear side of the motor, and the speed reduction means including the output gear assembled by spline fitting, screw fixing, etc. on the output shaft of the automatic transmission is accommodated in the adapter case. The power distribution means for taking out the output from the speed reduction means across the transmission main body case and the adapter case, for example, to the front wheel side with the output shaft facing the input shaft side of the automatic transmission at a required ratio An intermediate wall that positions and supports one or more of the gears constituting the speed reduction means in cooperation with the adapter case is fixed in the adapter case with bolts or the like. One in which you composed. Further, a parking gear is disposed between the transmission main body case and the intermediate wall in the adapter case.

この発明に係るこれらのいずれのアウトプット構造によっても、変速機本体ケースの後方側に連結されるアダプタケース内に所定の減速手段を配設し、そして、変速機本体ケースとアダプタケースとの両者に跨がって動力分配手段を配設して、従来技術ではトランスファ機構部１１４のケース１１８内に収納させていた多くの部分を、アダプタケース内および変速機本体ケース内に配設して、トランスファ機構の一部を自動変速機側に一体化することで、構造体のコンパクト化の下で、それの全長を従来技術に比して相当短くすることができ、この結果として、その構造体の適用性、ひいては、搭載性が大きく向上されることになる。
しかも、この発明に係るアウトプット構造では、減速手段を構成するギアの一枚以上を、アダプタケースとの協働下で位置決め支持する中間壁を、アダプタケース内に固定配置することにより、第１には、その中間壁を、変速機本体ケースとアダプタケースとの間に挟み込み固定する場合に比して、減速手段用のギアの支持剛性を高めることができ、第２には、中間壁をアダプタケースに、ボルト止め等によって固定することで、減速手段のサブアッセリブリが可能となり、ギア軸受けの予圧調整工程を、構造体の組立てとは別個独立に行うことができるので、全体の組立て時間を短縮することができ、第３には、中間壁をアダプタケースに固定することで、ギアの噛み合い反力の、変速機本体ケースへの直接的な入力を防止して、変速機本体ケースの剛性を確保するための、その本体ケースの肉厚増加を不要にすることができ、そして第４には、中間壁とアダプタケースとで、減速手段用のギアを挟み込むことで、油の掻き上げによるギアの歯面潤滑を容易にすることができるとう効果を奏することができる。 According to any of these output structures according to the present invention, a predetermined reduction means is disposed in an adapter case connected to the rear side of the transmission main body case, and both the transmission main body case and the adapter case are provided. The power distribution means is arranged across the many parts, and in the prior art, many parts stored in the case 118 of the transfer mechanism 114 are arranged in the adapter case and the transmission main body case, By integrating a part of the transfer mechanism on the automatic transmission side, the total length of the structure can be considerably shortened compared to the prior art under the compact structure. As a result, the structure Therefore, the applicability and the mountability are greatly improved.
Moreover, in the output structure according to the present invention, the intermediate wall for positioning and supporting one or more gears constituting the speed reduction means in cooperation with the adapter case is fixedly arranged in the adapter case, thereby Therefore, the support rigidity of the gear for the speed reduction means can be increased as compared with the case where the intermediate wall is sandwiched and fixed between the transmission main body case and the adapter case. By fixing to the adapter case with bolts, etc., the sub-assembly of the speed reduction means is possible, and the preload adjustment process of the gear bearing can be performed independently of the assembly of the structure, reducing the overall assembly time. Third, by fixing the intermediate wall to the adapter case, the gear meshing reaction force can be prevented from being directly input to the transmission body case, In order to ensure the rigidity of the case, it is possible to eliminate the need for an increase in the thickness of the main body case, and, fourthly, by inserting a gear for the speed reduction means between the intermediate wall and the adapter case, The effect of facilitating the tooth surface lubrication of the gear by scraping can be achieved.

図１は、この発明の実施の形態をその要部について示す部分縦断面図であり、図２は、減速手段のギアの噛み合い状態を示す展開平面図である。
図１，２中１は自動変速機を、２は、自動変速機１の出力軸を、そして３は、自動変速機１の変速機本体ケースをそれぞれ示す。また４は、変速機本体ケース３の後端に連結されて、トランスファ機構の一部を収納するアダプタケースを示す。 FIG. 1 is a partial longitudinal sectional view showing an essential part of an embodiment of the present invention, and FIG. 2 is a developed plan view showing a meshing state of gears of a speed reducing means.
1 and 2, reference numeral 1 denotes an automatic transmission, 2 denotes an output shaft of the automatic transmission 1, and 3 denotes a transmission main body case of the automatic transmission 1. Reference numeral 4 denotes an adapter case which is connected to the rear end of the transmission main body case 3 and accommodates a part of the transfer mechanism.

ここでは、自動変速機１の入力軸と同軸に配設した出力軸２の後端部に、減速手段５の一部としてのアウトプットギア５−１を、たとえばスプライン嵌合によって取り付けるとともに、このアウトプットギア５−１に、アイドラギア５−２およびカウタギア５−３を順次に噛合させて設けることによって減速手段５を構成する。   Here, an output gear 5-1 as a part of the speed reduction means 5 is attached to the rear end portion of the output shaft 2 arranged coaxially with the input shaft of the automatic transmission 1 by, for example, spline fitting. The speed reduction means 5 is configured by sequentially engaging the idler gear 5-2 and the counter gear 5-3 with the output gear 5-1.

またここでは、アダプタケース４に対して、上述した、アウトプットギア５−１およびアイドラギア５−２のそれぞれを挟み込む中間壁６を、変速機本体ケース３とアダプタケース４とのそれぞれの合わせ面３ａ，４ａより内側で、アダプタケース４にボルト７によって締め付け固定し、この中間壁６により、アダプタケース４との協働下で、上記のギア５−１および５−２を軸受け支持する。   Further, here, the intermediate wall 6 sandwiching the output gear 5-1 and the idler gear 5-2 with respect to the adapter case 4 is connected to the mating surfaces 3a of the transmission main body case 3 and the adapter case 4 respectively. , 4a, and is fastened and fixed to the adapter case 4 with bolts 7. The intermediate wall 6 supports the gears 5-1 and 5-2 in cooperation with the adapter case 4 by bearings.

この一方で、中間壁６の、自動変速機１側では、出力軸２上に、パーキングギア８を、たとえばスプライン嵌合によって取付ける。
ところで、中間壁６には、図２に示すところから明らかなように、潤滑油を、出力軸２の軸心から、アイドラギア５−２の軸受け部に導びく油路９を設けることが好ましい。 On the other hand, on the automatic transmission 1 side of the intermediate wall 6, the parking gear 8 is attached on the output shaft 2 by, for example, spline fitting.
By the way, it is preferable to provide the intermediate wall 6 with an oil passage 9 that guides the lubricating oil from the shaft center of the output shaft 2 to the bearing portion of the idler gear 5-2, as is apparent from FIG.

なお、減速手段５のカウタギア５−３は、これも図２に示すように、変速機本体ケース３とアダプタケース４とに跨がって配設されて、減速手段５からの出力を、たとえば前輪側へ取り出す動力分配手段１０の電磁クラック１０ａに、中心軸を介して駆動結合してなり、これらのことによれば、自動変速機１の出力軸２から、動力の一部を、減速手段５を介してその出力軸２の半径方向外方側へ取り出すとともに、取り出したこの動力を、動力分配手段１０によって、前輪側へ所要に応じた割合で分配して、自動変速機１の入力軸側に向く方向へ出力することができる。   As shown in FIG. 2, the counter gear 5-3 of the speed reduction unit 5 is disposed across the transmission main body case 3 and the adapter case 4, and outputs the output from the speed reduction unit 5, for example. It is drive-coupled to the electromagnetic crack 10a of the power distribution means 10 to be taken out to the front wheel side through the central shaft. According to these, a part of the power is decelerated from the output shaft 2 of the automatic transmission 1. 5 is taken out radially outward of the output shaft 2, and the taken-out power is distributed to the front wheels at a required ratio by the power distribution means 10 to input the input shaft of the automatic transmission 1. It can output in the direction facing the side.

図３は、上述したような構成の下での、減速手段を構成するそれぞれのギアの噛み合い態様を、アダプタケースの前方側から見て示す配置図であり、図４は、図３に示すところに中間壁を組付けた状態を示す図である。
図３に示すところでは、アダプタケース４内に配置した、減速手段５を構成するそれぞれのギア５−１，５−２，５−３の周縁近傍で、アダプタケース４に、中間壁６をボルト締めするための複数個の雌ねじ部１１を設けるとともに、好ましくは、これらの雌ねじ部１１の幾つかを、それらのギア５−１，５−２，５−３のそれぞれの噛み合い位置１２の近くで、各噛み合い位置１２を挟んで配置することで、それらの雌ねじ部１１の全てを、アダプタケース４の、変速機本体ケース３との合わせ面４ａより十分内側に位置させる。 FIG. 3 is a layout view showing how the gears constituting the speed reduction means are engaged when viewed from the front side of the adapter case under the configuration as described above, and FIG. 4 is a diagram showing FIG. It is a figure which shows the state which assembled | attached the intermediate wall.
In the place shown in FIG. 3, the intermediate wall 6 is bolted to the adapter case 4 in the vicinity of the periphery of each of the gears 5-1, 5-2 and 5-3 constituting the speed reduction means 5 disposed in the adapter case 4. A plurality of internal threaded portions 11 are provided for tightening, and preferably some of these internal threaded portions 11 are located near their respective meshing positions 12 of their gears 5-1, 5-2, 5-3. By arranging each meshing position 12 in between, all of the female screw portions 11 are positioned sufficiently inside the mating surface 4a of the adapter case 4 with the transmission main body case 3.

このように形成したアダプタケース４のそれぞれの雌ねじ部１１に、ボルト７をもって中間壁６を図４に示すように締め付け固定し、この中間壁６とアダプタケース４とで、アウトプットギア５−１およびアイドラギア５−２のそれぞれを、図２に示すように軸受け支持したときは、中間壁６に、ギア５−１，５−２に対する高い支持剛性を十分に発揮させることができ、しかも、中間壁６を、それぞれのギア５−１，５−２の周縁近傍で、そして、ギア５−１，５−２，５−３の相互の噛み合い位置の近くの、各噛み合い位置１２を挟む位置で、アダプタケース４にボルト固定することにより、相互に噛み合うギア５−１，５−２，５−３の噛み合い反力に対する中間壁６の捩り剛性を高めて、その噛み合い反力に起因するギアの倒れ変位を効果的に抑制することができる。   The intermediate wall 6 is fastened and fixed to each female thread portion 11 of the adapter case 4 thus formed with bolts 7 as shown in FIG. 4, and the output gear 5-1 is formed between the intermediate wall 6 and the adapter case 4. When each of the idler gear 5-2 and the idler gear 5-2 are supported by bearings as shown in FIG. 2, the intermediate wall 6 can sufficiently exhibit the high support rigidity with respect to the gears 5-1 and 5-2. The wall 6 is positioned in the vicinity of the peripheral edge of each gear 5-1, 5-2, and near the respective meshing positions of the gears 5-1, 5-2, 5-3, and sandwiching the meshing positions 12. By fixing the bolt to the adapter case 4, the torsional rigidity of the intermediate wall 6 against the meshing reaction force of the gears 5-1, 5-2, 5-3 meshing with each other is increased, and the gear caused by the meshing reaction force Falling displacement It can be effectively suppressed.

図５は、図４の、Ｘ１−Ｏ１−Ｏ２−Ｏ３−Ｘ２線に沿う断面図であり、この断面内では、アウトプットギア５−１とアイドラギア５−２とが、アダプタケース４と中間壁７との間にアッセンブリされた状態となっており、図４の、Ｘ１−Ｏ１−Ｏ２−Ｏ４−Ｘ３線に沿う断面を示す図６では、上述したところに加えて、アイドラギア５−２に噛合するカウンタギア５−３が、アダプタケース４に組み込まれた状態となっている。 FIG. 5 is a cross-sectional view taken along the line X 1 -O 1 -O 2 -O 3 -X 2 in FIG. 4. In this cross section, the output gear 5-1 and the idler gear 5-2 are connected to the adapter. FIG. 6 shows a cross section taken along line X 1 -O 1 -O 2 -O 4 -X 3 in FIG. 4 as described above. In addition, the counter gear 5-3 that meshes with the idler gear 5-2 is in a state of being incorporated in the adapter case 4.

また、図４に示すところでは、中間壁６上の、アイドラギア５−２の支持中心Ｏ２からオフセットさせた位置に、後に述べるパーキングポールの支持位置１３を設ける。
このことによれば、図１，２に示すように、アダプタケース４内で、変速機本体ケース３と中間壁６との間にパーキングギア８を配設することとの関連において、アイドラギア５−２のフロント側を軸受け支持するベアリング５−２ａを、自動変速機１側に近づけて配置することができて、アンドラギア５−２の支持スパンを長くできるので、アイドラギア５−２の倒れ変位をより有効に拘束することができる。 Further, in the method shown in FIG. 4, on the intermediate wall 6, a position is offset from the support center O 2 of the idler gear 5-2, provided support position 13 of the parking pawl to be described later.
According to this, as shown in FIGS. 1 and 2, the idler gear 5- in the adapter case 4 in relation to the disposition of the parking gear 8 between the transmission main body case 3 and the intermediate wall 6. The bearing 5-2a supporting the front side of the bearing 2 can be arranged close to the automatic transmission 1 side, and the support span of the Andorra gear 5-2 can be lengthened. It can be restrained more effectively.

ところで、パーキングギア８を、アダプタケース４内で、変速機本体ケース３と中間壁６との間に配設したときは、図７，８に示すように、パーキング装置関連部品を、その中間壁６に組み込むことが可能となるので、簡単な構造にして小型のパーキング装置を実現することができる。
すなわち、図７に示すように、中間壁６に、パーキングギア８をロックするためのパーキングポール１４および捩じりコイルスプリング１５を、ポールシャフト１６によって組付けるとともに、このポールシャフト１６のフロント側部分を、変速機本体ケース３によって支持し、また、サポートアクチュエータ１７もその中間壁６に組付けることで、簡単な構造の、小型のパーキング装置を実現することができる。 By the way, when the parking gear 8 is disposed between the transmission main body case 3 and the intermediate wall 6 in the adapter case 4, as shown in FIGS. 6 can be incorporated, so that a small parking device can be realized with a simple structure.
That is, as shown in FIG. 7, a parking pole 14 and a torsion coil spring 15 for locking the parking gear 8 are assembled to the intermediate wall 6 by a pole shaft 16, and a front side portion of the pole shaft 16 is assembled. Is supported by the transmission main body case 3 and the support actuator 17 is also assembled to the intermediate wall 6 to realize a small parking device having a simple structure.

これをいいかえれば、自動変速機１の後方側には、クラッチなどの回転構成部材が配設されるので、変速機本体ケース３の後方側に隣接させて減速手段５を配設すると、自動変速機１の回転構成部材の径よりも外周側で、中間壁をアダプタケースにボルト締め固定することが必要になり、中間壁を、減速手段を構成するそれぞれのギアの周縁近傍でアダプタケースにボルト固定することができなくなるので、それらのギアに対する支持剛性の低下が否めなくなるところ、図示のように、パーキングギア８を、自動変速機１のすぐ後方側に配設することで、パーキング装置を、構造の複雑化なしにコンパクトにレイアウトすることができ、併せて、減速手段５を構成するそれぞれのギアの支持固定用の中間壁６を、それぞれギアの周縁近傍でアダプタケース４にボルト締め固定することが可能となって、中間壁６による、それらのギアに対する支持剛性を有効に高めることができる。   In other words, since a rotating component such as a clutch is disposed on the rear side of the automatic transmission 1, if the speed reducing means 5 is disposed adjacent to the rear side of the transmission main body case 3, the automatic transmission is performed. The intermediate wall needs to be bolted and fixed to the adapter case on the outer peripheral side of the diameter of the rotating component of the machine 1, and the intermediate wall is bolted to the adapter case in the vicinity of the periphery of each gear constituting the speed reduction means. Since it becomes impossible to fix the reduction of the support rigidity for these gears, the parking gear 8 is arranged immediately behind the automatic transmission 1 as shown in the figure, so that the parking device A compact layout can be achieved without complicating the structure. At the same time, the intermediate walls 6 for supporting and fixing the gears constituting the speed reduction means 5 are arranged near the periphery of the gears. It becomes possible to fixedly bolted to Putakesu 4, according to the intermediate wall 6 can be enhanced to enable the supporting rigidity for those gears.

ところで、パーキング装置の全体は、上述したところに加え、図８に斜視図で示すように、変速機本体ケース３で回転自在に支持したマニュアルシャフト１８に、ポジションと連動するマニュアルプレート１９を固定し、そしてこのマニュアルプレート１９にリンク機構によって連結したパーキングロッド２０を設けることにより構成することができ、このパーキングロッド２０によって、サポートアクチュエータ１７の案内下でパーキングポール１４を変位させることで、パーキングギア８をロックおよびアンロックすることができる。   By the way, in addition to the above, the parking device as a whole has a manual plate 19 linked to a position fixed to a manual shaft 18 rotatably supported by the transmission body case 3 as shown in a perspective view of FIG. The parking rod 20 connected to the manual plate 19 by a link mechanism can be provided, and the parking rod 8 is displaced under the guidance of the support actuator 17 by the parking rod 20. Can be locked and unlocked.
