図１は、第１実施例のパワートレイン１をハイブリッド車両に搭載した場合の構成を表すスケルトン図である。
パワートレイン１は、エンジン２およびモータジェネレータ（モータ）３を走行用の動力源とするハイブリッド車両に搭載されている。パワートレイン１は、エンジン２およびモータジェネレータ３に加えて、変速機ユニット４を備える。変速機ユニット４は、第１インプットシャフトＩＮ１および第２インプットシャフトＩＮ２を入力とし、出力ギヤ（出力要素）ＯＵＴから駆動力を出力する。第１インプットシャフトＩＮ１は、エンジン２のクランクシャフトと接続する。第２インプットシャフトＩＮ２は、第１インプットシャフトＩＮ１と同軸上に配置され、モータジェネレータ３の出力軸と接続する。出力ギヤＯＵＴからの駆動力は、アイドラシャフト（平行軸）５およびデファレンシャル６を介してドライブシャフト７へ伝達され、駆動輪８の回転駆動に供される。[First embodiment]
FIG. 1 is a skeleton diagram showing the configuration when the powertrain 1 of the first embodiment is mounted on a hybrid vehicle.
A powertrain 1 is mounted on a hybrid vehicle having an engine 2 and a motor generator (motor) 3 as power sources for running. A powertrain 1 includes a transmission unit 4 in addition to an engine 2 and a motor generator 3 . The transmission unit 4 receives inputs from the first input shaft IN1 and the second input shaft IN2, and outputs driving force from an output gear (output element) OUT. The first input shaft IN1 connects with the crankshaft of the engine 2 . Second input shaft IN2 is arranged coaxially with first input shaft IN1 and is connected to the output shaft of motor generator 3 . A driving force from the output gear OUT is transmitted to a drive shaft 7 via an idler shaft (parallel shaft) 5 and a differential 6, and used to rotationally drive drive wheels 8.

変速機ユニット４は、遊星歯車組を構成する第１サンギヤＳ１、第１ピニオンＰ１、リングギヤＲ、第２サンギヤＳ２、第２ピニオンＰ２およびキャリアＰＣと、４つの締結要素としての第１クラッチＣ１、第２クラッチＣ２、第１ブレーキＢ１および第２ブレーキＢ２と、を備える。
第１サンギヤＳ１は、第２インプットシャフトＩＮ２と接続する。第１ピニオンＰ１は、第１サンギヤＳ１およびリングギヤＲの両方と噛み合う。第２サンギヤＳ２は、第１サンギヤＳ１と同軸上に配置されている。第２ピニオンＰ２は、第２サンギヤＳ２および第１ピニオンＰ１の両方と噛み合う。キャリアＰＣは、出力ギヤＯＵＴと接続され、第１ピニオンＰ１および第２ピニオンＰ２を回転可能に軸支する。The transmission unit 4 includes a first sun gear S1, a first pinion P1, a ring gear R, a second sun gear S2, a second pinion P2 and a carrier PC, which form a planetary gear set, and a first clutch C1 as four engagement elements. A second clutch C2, a first brake B1 and a second brake B2 are provided.
The first sun gear S1 connects with the second input shaft IN2. The first pinion P1 meshes with both the first sun gear S1 and the ring gear R. The second sun gear S2 is arranged coaxially with the first sun gear S1. The second pinion P2 meshes with both the second sun gear S2 and the first pinion P1. The carrier PC is connected to the output gear OUT and rotatably supports the first pinion P1 and the second pinion P2.

図２は、第１実施例の遊星歯車組のサンギヤ、ピニオンおよびリングギヤの噛み合い関係を表す概略図である。
第１ピニオンＰ１は、軸方向に延在することで第１サンギヤＳ１および第２ピニオンＰ２の両方と径方向から見て重なるように形成されたロングピニオンである。第１ピニオンＰ１は、第２ピニオンＰ２と常時噛み合い、第２サンギヤＳ２とは噛み合わない。よって、変速機ユニット４は、第１サンギヤＳ１とリングギヤＲとの間では、シングルピニオン型遊星歯車として機能し、第２サンギヤＳ２とリングギヤＲとの間では、ダブルピニオン型遊星歯車として機能する。
第１クラッチＣ１は、第１インプットシャフトＩＮ１と第１サンギヤＳ１とを選択的に断接可能である。第２クラッチＣ２は、第１インプットシャフトＩＮ１とリングギヤＲとを選択的に断接可能である。第１ブレーキＢ１は、第２サンギヤＳ２と変速機ユニット４のケース９とを選択的に固定可能である。第２ブレーキＢ２は、リングギヤＲとケース９とを選択的に固定可能である。FIG. 2 is a schematic diagram showing the meshing relationship of the sun gear, pinion and ring gear of the planetary gear set of the first embodiment.
The first pinion P1 is a long pinion formed so as to overlap both the first sun gear S1 and the second pinion P2 when viewed in the radial direction by extending in the axial direction. The first pinion P1 is always meshed with the second pinion P2 and is not meshed with the second sun gear S2. Therefore, the transmission unit 4 functions as a single pinion planetary gear between the first sun gear S1 and the ring gear R, and functions as a double pinion planetary gear between the second sun gear S2 and the ring gear R.
The first clutch C1 can selectively connect and disconnect the first input shaft IN1 and the first sun gear S1. The second clutch C2 can selectively connect and disconnect the first input shaft IN1 and the ring gear R. The first brake B<b>1 can selectively fix the second sun gear S<b>2 and the case 9 of the transmission unit 4 . The second brake B<b>2 can selectively fix the ring gear R and the case 9 .

図３は第１実施例の変速機ユニット４の締結表であり、図４は第１実施例の変速機ユニット４の共線図である。共線図とは、横軸の各回転要素をギヤ比に応じた軸間距離で配置し、縦軸に各回転要素の回転速度を表記した図である。共線図では、ギヤの噛み合いによる各回転要素の関係は、各回転要素を直線で結んだ剛体レバーで表記される。変速機ユニット４の変速は、剛体レバーの回動により表現される。
第１実施例のパワートレイン１は、走行モードとして、ＥＶモードおよびＩＣＥモードを有する。ＥＶモードは、モータジェネレータ３の駆動力のみで走行する走行モードである。ＩＣＥモードは、エンジン２（またはエンジン２とモータジェネレータ３）の駆動力で走行する走行モードである。ＥＶモードは、第２ブレーキＢ２の締結によりＥＶ１速（ギヤ比２．９７）を達成し、第１ブレーキＢ１の締結によりＥＶ２速（ギヤ比１．６３）を達成する。
ＩＣＥモードは、第１クラッチＣ１と第２ブレーキＢ２の締結によりＩＣＥ１速（ギヤ比２．９７）を達成し、第１クラッチＣ１と第１ブレーキＢ１の締結によりＩＣＥ２速（ギヤ比１．６３）を達成し、第１クラッチＣ１と第２クラッチＣ２の締結によりＩＣＥ３速（ギヤ比１．００）を達成し、第２クラッチＣ２と第１ブレーキＢ１の締結によりＩＣＥ４速（ギヤ比０．６８）を達成する。

A collinear chart is a diagram in which each rotating element on the horizontal axis is arranged at an inter-axis distance according to the gear ratio, and the rotation speed of each rotating element is written on the vertical axis. In the collinear diagram, the relationship between each rotating element due to gear meshing is represented by a rigid lever that connects each rotating element with a straight line. The speed change of the transmission unit 4 is represented by the rotation of the rigid lever.
The powertrain 1 of the first embodiment has an EV mode and an ICE mode as running modes. The EV mode is a running mode in which the vehicle runs only with the driving force of the motor generator 3 . The ICE mode is a driving mode in which the vehicle is driven by the driving force of the engine 2 (or the engine 2 and the motor generator 3). In the EV mode, EV 1st speed (gear ratio: 2.97) is achieved by engaging the second brake B2, and EV 2nd speed (gear ratio: 1.63) is achieved by engaging the first brake B1.
In the ICE mode, ICE 1st speed (gear ratio: 2.97) is achieved by engaging the first clutch C1 and the second brake B2, and ICE 2nd speed (gear ratio: 1.63) is achieved by engaging the first clutch C1 and the first brake B1. , ICE 3rd speed (gear ratio 1.00) is achieved by engaging the first clutch C1 and the second clutch C2, and ICE 4th speed (gear ratio 0.68) is achieved by engaging the second clutch C2 and the first brake B1. to achieve
As described above, in the powertrain 1 of the first embodiment, it is possible to improve mountability on the vehicle while simplifying the components. In addition, it is possible to achieve 2nd speed in EV and 4th speed in engine driving.

また、第１実施例のパワートレイン１は、最小限の構成変更でもって、モータを走行用の動力源とする電気自動車のパワートレインとしても使用可能である。図５は、第１実施例のパワートレイン１を電気自動車に搭載した場合の構成を表すスケルトン図である。パワートレイン１は、図１に示した構成に対し、第１クラッチＣ１および第２クラッチＣ２を廃止した点、およびモータジェネレータ３を中空モータ化し、第２インプットシャフトＩＮ２をドライブシャフト７と同軸上に配置した点で相違する。パワートレイン１は、第２ブレーキＢ２の締結によりＥＶ１速（ギヤ比２．９７）を達成し、第１ブレーキＢ１の締結によりＥＶ２速（ギヤ比１．６３）を達成する。なお、変速機ユニット４の共線図は、図４に示したＩＣＥ１速、ＩＣＥ２速と同じである。 Further, the powertrain 1 of the first embodiment can be used as a powertrain of an electric vehicle using a motor as a power source for running, with a minimum configuration change. FIG. 5 is a skeleton diagram showing the configuration when the powertrain 1 of the first embodiment is mounted on an electric vehicle. Compared to the configuration shown in FIG. 1, the powertrain 1 is different from the configuration shown in FIG. They are different in terms of arrangement. The powertrain 1 achieves EV 1st speed (gear ratio 2.97) by engaging the second brake B2, and achieves EV 2nd speed (gear ratio 1.63) by engaging the first brake B1. Note that the nomographic chart of the transmission unit 4 is the same as the ICE 1st speed and the ICE 2nd speed shown in FIG.

一般的に、電気自動車のパワートレイン（特に変速機）とハイブリッド車両のパワートレインは、互いに構造が異なるため、それぞれ専用の製造設備が必要である。一方、電気自動車およびハイブリッド車両は未だ普及率が低いため、パワートレインの製造設備をそれぞれ別々にした場合、コスト面で不利である。これに対し、第１実施例のパワートレイン１は、２つのクラッチ（第１クラッチＣ１および第２クラッチＣ２）の追加または廃止という最小限の構成変更でもって、ハイブリッド車両のパワートレインまたは電気自動車のパワートレインとして使用できる。つまり、第１実施例のパワートレイン１を採用することにより、電気自動車用のパワートレインとハイブリッド車両用のパワートレインとでほとんどの部品を共用化できるため、同一の製造設備で製造可能である。この結果、スケールメリットによるコストダウンを図れる。
第１実施例のパワートレイン１では、モータジェネレータ３を中空モータとし、ドライブシャフト７と同軸上に配置したことにより、異軸とした場合と比べて径方向の寸法を小さくでき、車両搭載性を向上できる。また、その分だけモータジェネレータ３の外形サイズを大きくできるため、出力アップを図れる。In general, electric vehicle powertrains (especially transmissions) and hybrid vehicle powertrains have different structures, and therefore require dedicated manufacturing facilities for each. On the other hand, electric vehicles and hybrid vehicles are still not widely used, so separate production facilities for powertrains are disadvantageous in terms of cost. On the other hand, the powertrain 1 of the first embodiment is a powertrain of a hybrid vehicle or an electric vehicle with a minimum configuration change of adding or eliminating two clutches (first clutch C1 and second clutch C2). Can be used as a powertrain. That is, by adopting the powertrain 1 of the first embodiment, most of the parts can be shared between the powertrain for electric vehicles and the powertrain for hybrid vehicles, so that they can be manufactured with the same manufacturing facility. As a result, cost reduction can be achieved through economies of scale.
In the powertrain 1 of the first embodiment, the motor-generator 3 is a hollow motor and is arranged coaxially with the drive shaft 7, so that the radial dimension can be made smaller than in the case of using a different shaft, and vehicle mountability is improved. can improve. In addition, since the external size of the motor generator 3 can be increased by that amount, the output can be increased.

In addition, 2nd speed can be achieved in EV running, and 4th speed can be achieved in engine running. Furthermore, since it can be used as a power train of an electric vehicle simply by eliminating the first clutch C1 and the second clutch C2, it is possible to reduce costs by economies of scale.
