従来、モータジェネレータをエンジンおよび有段変速部のうち一方に選択的に接続可能な動力伝達装置が知られている。   2. Description of the Related Art Conventionally, there is known a power transmission device capable of selectively connecting a motor generator to one of an engine and a stepped transmission unit.

米国公開US2012/0186392A1US release US2012 / 0186392A1

この種の動力伝達装置では、例えば、モータジェネレータをより効率良く利用することができるなど、よりメリットが多くあるいはよりデメリットが少ない新規な構成の動力伝達装置が得られれば、望ましい。   In this type of power transmission device, it is desirable if a power transmission device having a new configuration with more merit or less demerit can be obtained, for example, the motor generator can be used more efficiently.

そこで、本発明の課題の一つは、例えば、よりメリットが多くあるいはよりデメリットが少ない新規な構成の動力伝達装置を得ることである。   Therefore, one of the problems of the present invention is to obtain a power transmission device having a novel configuration with, for example, more merit or less demerit.

本発明の動力伝達装置は、例えば、第一のシャフトと、当該第一のシャフトと平行な第二のシャフトと、上記第一のシャフトによって回転されるドライブギヤと当該ドライブギヤに直接またはアイドラを介して噛み合い上記第二のシャフトを回転するドリブンギヤとをそれぞれ含み互いにギヤ比が異なる複数のギヤ段と、上記複数のギヤ段のうちいずれか一つを選択する選択機構と、を有し、当該選択機構によって選択された上記ギヤ段を介して上記第一のシャフトの回転を上記第二のシャフトに伝達する、有段変速部と、モータジェネレータのシャフトと連動して回転する第一の回転要素と、エンジンのシャフトと連動して回転可能な第二の回転要素と、上記第二のシャフトと連動して回転する第三の回転要素と、上記第一のシャフトと連動して回転する第四の回転要素と、上記第一の回転要素と上記第二の回転要素との回転伝達状態と回転遮断状態とを切り替える第一の切替機構と、上記第一の回転要素と上記第三の回転要素との回転伝達状態と回転遮断状態とを切り替える第二の切替機構と、上記第一の回転要素と上記第四の回転要素との回転伝達状態と回転遮断状態とを切り替える第三の切替機構と、を備える。よって、例えば、モータジェネレータと有段変速部とをより効率良く利用した運転モードが実現されうる。   The power transmission device of the present invention includes, for example, a first shaft, a second shaft parallel to the first shaft, a drive gear rotated by the first shaft, and an idler directly or on the drive gear.

Therefore, the fixed portion of the movable portion 2EO and the first outer shaft 6E is an example of the first switching mechanism 210.

可動部2EOおよび第二のアウタシャフト6Oの固定部は、第一のインナシャフト6Mと第二のアウタシャフト6Oとの回転伝達状態と回転遮断状態とを切り替える。すなわち、可動部2EOおよび第二のアウタシャフト6Oの固定部は、モータジェネレータMGのシャフト6mとホイールWとの回転伝達状態と回転遮断状態とを切り替える。よって、可動部2EOおよび第二のアウタシャフト6Oの固定部は、第二の切替機構220の一例である。   The fixed portion of the movable portion 2EO and the second outer shaft 6O switches between a rotation transmission state and a rotation cutoff state between the first inner shaft 6M and the second outer shaft 6O.

選択機構の一部を構成する可動部7Rは、第二のアウタシャフト6Oと一体に回転する。また、可動部7Rは、第二のアウタシャフト6Oの軸方向に沿って、二つの位置の間で移動可能に設けられている。二つの位置には、可動部7Rがギヤ6rに固定された固定部と噛み合う接続位置(噛合位置)と、可動部7Rが当該固定部から離間した遮断位置(切離位置、中立位置)と、が含まれる。可動部7Rおよび固定部は、例えばドグクラッチを構成しうる。この場合、可動部7Rは、例えば、スリーブを含み、固定部は、例えば、スリーブと噛み合うハブを含む。なお、ドグクラッチには、シンクロナイザが設けられうる。   The movable portion 7R constituting a part of the selection mechanism rotates integrally with the second outer shaft 6O. The movable portion 7R is provided so as to be movable between two positions along the axial direction of the second outer shaft 6O. The two positions include a connection position (meshing position) where the movable part 7R meshes with a fixed part fixed to the gear 6r, and a blocking position (a disconnected position, a neutral position) where the movable part 7R is separated from the fixed part, Is included.

For example, the second switching mechanism 220 may switch between a rotation transmission state and a rotation cut-off state between the shaft 6m of the motor generator MG and the second output shaft 22. The switching unit 200A includes a second switching mechanism 220 that switches between a rotation transmission state and a rotation cutoff state between the shaft 6m of the motor generator MG and the first output shaft 21, and the shaft 6m of the motor generator MG and the second You may equip in parallel with the 2nd switching mechanism 220 which switches a rotation transmission state with the output shaft 22, and a rotation interruption | blocking state. The switching unit 200 </ b> A has a plurality of parallel third rotating elements that rotate in conjunction with one of the first output shaft 21 and the second output shaft 22, and includes a plurality of third rotating elements. The gear ratio (rotational speed ratio) between each of the first output shaft 21 and the second output shaft 22 may be different from each other. The third rotating element may be interlocked with the first output shaft 21 or may be interlocked with the second output shaft 22. In this case, the switching unit 200 </ b> A may include a plurality of third rotating elements that are linked to the first output shaft 21, or may have a plurality of rotating elements that are linked to the second output shaft 22. Alternatively, it may have a third rotating element interlocked with the first output shaft 21 and a third rotating element interlocked with the second output shaft 22. Further, the specifications (configuration, number, position, arrangement, size, number of gear steps, number of teeth, etc.) of the switching unit 200A can be variously changed.

制御装置8は、例えば、ECU(electronic control unit)である。制御装置8は、例えば、CPU(central processing unit)を含む。CPUは、主記憶装置等にインストールされたプログラムにしたがって演算処理を実行し、第一の切替機構210や、第二の切替機構220、クラッチC等を制御する。なお、制御装置8は、FPGA(field programmable gate array)やASIC(application specific integrated circuit)等のハードウエアを含むことができ、これらハードウエアによって各部の制御を実行してもよい。   The control device 8 is, for example, an ECU (electronic control unit). The control device 8 includes, for example, a CPU (central processing unit). The CPU executes arithmetic processing according to a program installed in the main storage device or the like, and controls the first switching mechanism 210, the second switching mechanism 220, the clutch C, and the like. The control device 8 can include hardware such as a field programmable gate array (FPGA) and an application specific integrated circuit (ASIC), and the control of each unit may be executed by these hardware.

以下、動力伝達装置1Aによる種々の運転モードについて説明する。なお、以下では、制御装置8が、第一の切替機構210、第二の切替機構220、およびクラッチCの回転伝達状態と回転遮断状態とを切り替える構成について例示する。   Hereinafter, various operation modes by the power transmission device 1A will be described. Hereinafter, a configuration in which the control device 8 switches between the first switching mechanism 210, the second switching mechanism 220, and the rotation transmission state and the rotation cutoff state of the clutch C will be exemplified.

(1−1 エンジン始動モード、アイドルストップモード)
このモードでは、制御装置8は、第一の切替機構210を回転伝達状態とし、第二の切替機構220を回転遮断状態とし、クラッチCを回転遮断状態とする。モータジェネレータMGによるエンジンEGの始動に備えた状態であるため、速やかにエンジンEGの始動に備えることができる。なお、有段変速部100が、いずれの変速段も選択されていない所謂ニュートラル状態であれば、クラッチCは回転接続状態でも構わない。ただし、クラッチCが回転遮断状態である場合には、クラッチCが回転接続状態である場合に比べて、回転負荷、すなわちモータジェネレータMGによる消費エネルギはより少なくて済む。
(1-1 Engine start mode, idle stop mode)
In this mode, the control device 8 sets the first switching mechanism 210 in the rotation transmission state, sets the second switching mechanism 220 in the rotation cutoff state, and puts the clutch C in the rotation cutoff state. Since the motor generator MG is ready for starting the engine EG, the engine EG can be quickly started. Note that the clutch C may be in a rotationally connected state as long as the stepped transmission unit 100 is in a so-called neutral state in which no gear stage is selected. However, when the clutch C is in the rotation cut-off state, less energy is consumed by the rotational load, that is, the motor generator MG than when the clutch C is in the rotationally connected state.

(1−2 停車時充電モード)
このモードでは、制御装置8は、第一の切替機構210を回転伝達状態とし、第二の切替機構220を回転遮断状態とし、クラッチCを回転遮断状態とする。エンジンEGによってモータジェネレータMGを回転して発電させ、不図示のバッテリを充電することができる。なお、有段変速部100が、いずれの変速段も選択されていない所謂ニュートラル状態であれば、クラッチCは回転接続状態でも構わない。ただし、クラッチCが回転遮断状態である場合には、クラッチCが回転接続状態である場合に比べて、回転負荷、すなわちエンジンEGによる消費エネルギはより少なくて済む。
(1-2 Charging mode when stopped)
In this mode, the control device 8 sets the first switching mechanism 210 in the rotation transmission state, sets the second switching mechanism 220 in the rotation cutoff state, and puts the clutch C in the rotation cutoff state. The motor MG can be rotated by the engine EG to generate power, and a battery (not shown) can be charged. Note that the clutch C may be in a rotationally connected state as long as the stepped transmission unit 100 is in a so-called neutral state in which no gear stage is selected. However, when the clutch C is in the rotation cut-off state, less energy is consumed by the rotational load, that is, the engine EG than when the clutch C is in the rotationally connected state.

(1−3 EV走行モード)
このモードでは、制御装置8は、第一の切替機構210を回転遮断状態とし、第二の切替機構220を回転伝達状態とし、クラッチCを回転遮断状態とする。これにより、モータジェネレータMGは、ホイールWを回転し、車両を電気自動車として走行させることができる。
(1-3 EV travel mode)
In this mode, the control device 8 puts the first switching mechanism 210 in the rotation cut-off state, puts the second switching mechanism 220 in the rotation transmission state, and puts the clutch C in the rotation cut-off state. Thereby, motor generator MG can rotate wheel W and drive the vehicle as an electric vehicle.

(1−4 EV走行時のエンジン始動モード)
このモードでは、制御装置8は、第一の切替機構210を回転遮断状態とし、第二の切替機構220を回転伝達状態とし、クラッチCを回転遮断状態から回転伝達状態に切り替える。これにより、モータジェネレータMGが生じたトルクを、ホイールWに伝達するとともに、エンジンEGに伝達することができ、これにより、車両の走行中に、エンジンEGを始動することができる。
(1-4 Engine start mode during EV travel)
In this mode, the control device 8 sets the first switching mechanism 210 to the rotation cutoff state, sets the second switching mechanism 220 to the rotation transmission state, and switches the clutch C from the rotation cutoff state to the rotation transmission state. Thereby, the torque generated by motor generator MG can be transmitted to wheel W and also transmitted to engine EG, so that engine EG can be started while the vehicle is traveling.

(1−5 エンジン走行モード)
このモードでは、制御装置8は、第一の切替機構210を回転遮断状態とし、第二の切替機構220を回転遮断状態とし、クラッチCを回転伝達状態とする。これにより、エンジンEGは、有段変速部100を介してホイールWを回転し、車両を走行させることができる。この場合、第一の切替機構210および第二の切替機構220が回転遮断状態であるため、モータジェネレータMGや切替部200Aの負荷によるエネルギロスの増大が、抑制される。
(1-5 Engine travel mode)
In this mode, the control device 8 sets the first switching mechanism 210 in the rotation cutoff state, sets the second switching mechanism 220 in the rotation cutoff state, and puts the clutch C in the rotation transmission state. As a result, the engine EG can rotate the wheel W via the stepped transmission 100 and drive the vehicle. In this case, since the first switching mechanism 210 and the second switching mechanism 220 are in the rotation cut-off state, an increase in energy loss due to the load on the motor generator MG and the switching unit 200A is suppressed.

(1−6 ハイブリッド走行モード)
このモードでは、制御装置8は、第一の切替機構210を回転遮断状態とし、第二の切替機構220を回転伝達状態とし、クラッチCを回転伝達状態とする。これにより、例えば、比較的大きな車両加速度が必要な場合等において、エンジンEGおよびモータジェネレータMGの双方によってホイールWを回転させることができる。
(1-6 Hybrid driving mode)
In this mode, the control device 8 puts the first switching mechanism 210 into the rotation cut-off state, puts the second switching mechanism 220 into the rotation transmission state, and puts the clutch C into the rotation transmission state. Thereby, for example, when a relatively large vehicle acceleration is required, the wheel W can be rotated by both the engine EG and the motor generator MG.

(1−7 充電走行モード)
このモードでは、制御装置8は、第一の切替機構210を回転遮断状態とし、第二の切替機構220を回転伝達状態とし、クラッチCを回転伝達状態とする。これにより、例えば、車両が定速あるいは比較的低い加速度で走行している場合等において、エンジンEGのトルクにより有段変速部100を介してホイールWを回転させるとともに、モータジェネレータMGを回転して発電させ、不図示のバッテリを充電することができる。
(1-7 Charging mode)
In this mode, the control device 8 puts the first switching mechanism 210 into the rotation cut-off state, puts the second switching mechanism 220 into the rotation transmission state, and puts the clutch C into the rotation transmission state. Thereby, for example, when the vehicle is traveling at a constant speed or relatively low acceleration, the wheel W is rotated via the stepped transmission unit 100 by the torque of the engine EG, and the motor generator MG is rotated. It is possible to generate power and charge a battery (not shown).

(1−8 回生モード)
このモードでは、制御装置8は、第一の切替機構210を回転遮断状態とし、第二の切替機構220を回転伝達状態とし、クラッチCを回転遮断状態とする。これにより、例えば、車両の減速時に、ホイールWのトルクによってモータジェネレータMGを回転して発電させ、不図示のバッテリを充電することができる。運動エネルギが電気エネルギに変換されることにより、車両が減速する。
(1-8 regeneration mode)
In this mode, the control device 8 puts the first switching mechanism 210 in the rotation cut-off state, puts the second switching mechanism 220 in the rotation transmission state, and puts the clutch C in the rotation cut-off state. Thereby, for example, when the vehicle is decelerated, the motor generator MG is rotated by the torque of the wheel W to generate electric power, and a battery (not shown) can be charged. The vehicle is decelerated by converting kinetic energy into electrical energy.

以上、説明したように、本実施形態の動力伝達装置1Aでは、後進の変速段5R(ギヤ段)におけるアイドラ(ギヤ6rおよび第二のアウタシャフト6O)は、第一のインナシャフト6M(第一の回転要素)と同軸に配置されている。また、アイドラは、第一のインナシャフト6Mを覆い、当該第一のインナシャフト6Mの周囲を回転可能に設けられている。よって、例えば、アイドラが第一のインナシャフト6Mと平行な軸回りに回転可能に設けられた構成と比較して、動力伝達装置1Aをよりコンパクトに構成することができる。   As described above, in the power transmission device 1A of the present embodiment, the idler (gear 6r and second outer shaft 6O) in the reverse shift stage 5R (gear stage) is the first inner shaft 6M (first stage). Of the rotating element). The idler covers the first inner shaft 6M and is provided so as to be rotatable around the first inner shaft 6M. Therefore, for example, the power transmission device 1A can be configured more compactly as compared with a configuration in which the idler is provided to be rotatable around an axis parallel to the first inner shaft 6M.

また、本実施形態の動力伝達装置1Aでは、モータジェネレータMGと第一のアウトプットシャフト21との間の回転伝達経路として機能する第二のアウタシャフト6O(第三の回転要素)は、後進の変速段5R(ギヤ段)におけるアイドラの一部として構成されている。よって、例えば、第二のアウタシャフト6Oとは別に後進の変速段5R用のアイドラを設けた場合に比べて、有段変速部100ひいては動力伝達装置1Aをより簡素に、より小さく、あるいはより軽量に、構成することができる。   Further, in the power transmission device 1A of the present embodiment, the second outer shaft 6O (third rotation element) that functions as a rotation transmission path between the motor generator MG and the first output shaft 21 is a reverse shift. It is configured as a part of the idler in the stage 5R (gear stage). Therefore, for example, compared to the case where an idler for the reverse shift stage 5R is provided separately from the second outer shaft 6O, the stepped transmission unit 100 and the power transmission device 1A are made simpler, smaller, or lighter. It can be configured.

また、本実施形態の動力伝達装置1Aでは、第二のインナシャフト12(中間シャフト)は、エンジンEGのシャフト1eと第一のアウタシャフト6E(第二の回転要素)との間で回転を伝達し、インプットシャフト11(第一のシャフト)と同軸に設けられ、インプットシャフト11に覆われている。よって、例えば、エンジンEGの反対側に第一のアウタシャフト6Eを配置する構成が、比較的容易に実現されやすい。ひいては、例えば、エンジンEGや、クラッチC、その周辺部品等の構成や配置を従来から大幅に変更することなく、動力伝達装置1Aを構成することができる。   In the power transmission device 1A of the present embodiment, the second inner shaft 12 (intermediate shaft) transmits rotation between the shaft 1e of the engine EG and the first outer shaft 6E (second rotating element). The input shaft 11 (first shaft) is provided coaxially and is covered by the input shaft 11. Therefore, for example, a configuration in which the first outer shaft 6E is disposed on the opposite side of the engine EG is relatively easily realized. As a result, for example, the power transmission device 1A can be configured without significantly changing the configuration and arrangement of the engine EG, the clutch C, and peripheral components thereof.

また、本実施形態の動力伝達装置1Aでは、制御装置8は、不図示のアクチュエータを制御することにより、エンジンEGのシャフト1eと有段変速部100との間に設けられたクラッチC(摩擦クラッチ)の、回転伝達状態と回転遮断状態との切り替えを制御する。よって、例えば、より多くの動作モードが、よりエネルギロスが少ない状態で、実現されうる。   In the power transmission device 1A of the present embodiment, the control device 8 controls a clutch C (friction clutch) provided between the shaft 1e of the engine EG and the stepped transmission 100 by controlling an actuator (not shown). ) Of the rotation transmission state and the rotation cut-off state. Therefore, for example, more operation modes can be realized with less energy loss.

The switching unit 200B is different from the switching unit 200A of the first embodiment. That is, the switching unit 200 </ b> B includes a third switching mechanism 230 in addition to the first switching mechanism 210 and the second switching mechanism 220. The functions of the first switching mechanism 210 and the second switching mechanism 220 are the same as those in the first embodiment. The third switching mechanism 230 switches between a rotation transmission state and a rotation blocking state between the motor generator MG and the input shaft 11 (first shaft) of the stepped transmission unit 100. When the control device 8 switches between the first switching mechanism 210, the second switching mechanism 220, the third switching mechanism 230, and the rotation transmission state and the rotation cutoff state of the clutch C, more operation modes are more efficient. It can be realized well.

図4は、動力伝達装置1Bの例示的かつ模式的な構成図である。図4に示されるように、切替部200Bにおいて、第三のアウタシャフト6Iは、第一のインナシャフト6Mを覆い、第一のインナシャフト6Mと同軸で回転可能に、すなわち回転中心Ax61回りに回転可能に設けられている。   FIG. 4 is an exemplary schematic diagram of the power transmission device 1B. As shown in FIG. 4, in the switching unit 200B, the third outer shaft 6I covers the first inner shaft 6M and can rotate coaxially with the first inner shaft 6M, that is, rotate around the rotation center Ax61. It is provided as possible.

第三のアウタシャフト6Iは、インプットシャフト11と連動して回転する。本実施形態では、第三のアウタシャフト6Iには、ギヤ6iが固定され、当該ギヤ6iは、第一のアウトプットシャフト21に回転可能に支持されたドリブンギヤ43と噛み合っている。ドリブンギヤ43は、インプットシャフト11と固定されて一体に回転するドライブギヤ335と噛み合っている。したがって、第三のアウタシャフト6Iは、ギヤ6i、ドリブンギヤ43、およびドライブギヤ335を介してインプットシャフト11と連動して回転する。第三のアウタシャフト6Iは、第四の回転要素の一例である。   The third outer shaft 6 </ b> I rotates in conjunction with the input shaft 11. In the present embodiment, a gear 6i is fixed to the third outer shaft 6I, and the gear 6i meshes with a driven gear 43 that is rotatably supported by the first output shaft 21. The driven gear 43 meshes with a drive gear 335 that is fixed to the input shaft 11 and rotates integrally. Therefore, the third outer shaft 6I rotates in conjunction with the input shaft 11 via the gear 6i, the driven gear 43, and the drive gear 335. The third outer shaft 6I is an example of a fourth rotating element.

切替部200Bは、可動部2EIを含む。可動部2EIは、第一のインナシャフト6Mと一体に回転する。また、可動部2EIは、第一のインナシャフト6Mの軸方向に沿って、三つの位置の間で移動可能に設けられている。三つの位置には、可動部2EIが第一のアウタシャフト6Eおよび第三のアウタシャフト6Iのそれぞれに固定された固定部と噛み合う接続位置(噛合位置)と、可動部2EIが当該固定部から離間した遮断位置(切離位置、中立位置)と、が含まれる。可動部2EIの位置は、制御装置8(図3参照)によって制御されたアクチュエータ82により、変更される。可動部2EIおよび固定部は、例えばドグクラッチを構成しうる。この場合、可動部2EIは、例えば、スリーブを含み、固定部は、例えば、スリーブと噛み合うハブを含む。なお、ドグクラッチには、シンクロナイザが設けられうる。   Switching unit 200B includes a movable unit 2EI. The movable part 2EI rotates integrally with the first inner shaft 6M. The movable portion 2EI is provided so as to be movable between three positions along the axial direction of the first inner shaft 6M. The three positions include a connection position (meshing position) where the movable portion 2EI meshes with a fixed portion fixed to each of the first outer shaft 6E and the third outer shaft 6I, and the movable portion 2EI is separated from the fixed portion. Cut-off position (separation position, neutral position). The position of the movable part 2EI is changed by the actuator 82 controlled by the control device 8 (see FIG. 3). The movable part 2EI and the fixed part can constitute a dog clutch, for example. In this case, the movable portion 2EI includes, for example, a sleeve, and the fixed portion includes, for example, a hub that meshes with the sleeve. The dog clutch can be provided with a synchronizer.

可動部2EIおよび第一のアウタシャフト6Eの固定部は、第一のインナシャフト6Mと第一のアウタシャフト6Eとの回転伝達状態と回転遮断状態とを切り替える。すなわち、可動部2EIおよび第一のアウタシャフト6Eの固定部は、モータジェネレータMGのシャフト6mとエンジンEGのシャフト1eとの回転伝達状態と回転遮断状態とを切り替える。よって、可動部2EIおよび第一のアウタシャフト6Eの固定部は、第一の切替機構210の一例である。   The movable portion 2EI and the fixed portion of the first outer shaft 6E switch between a rotation transmission state and a rotation cut-off state between the first inner shaft 6M and the first outer shaft 6E. That is, the movable portion 2EI and the fixed portion of the first outer shaft 6E switch between a rotation transmission state and a rotation cut-off state between the shaft 6m of the motor generator MG and the shaft 1e of the engine EG. Therefore, the fixed portion of the movable portion 2EI and the first outer shaft 6E is an example of the first switching mechanism 210.

可動部2EIおよび第三のアウタシャフト6Iの固定部は、第一のインナシャフト6Mと第三のアウタシャフト6Iとの回転伝達状態と回転遮断状態とを切り替える。すなわち、可動部2EIおよび第三のアウタシャフト6Iの固定部は、モータジェネレータMGのシャフト6mとインプットシャフト11との回転伝達状態と回転遮断状態とを切り替える。よって、可動部2EIおよび第三のアウタシャフト6Iの固定部は、第三の切替機構230の一例である。なお、第三の切替機構230は、可動部734がドリブンギヤ43の固定部と接続されていない状態で、回転伝達状態となる。   The fixed portion of the movable portion 2EI and the third outer shaft 6I switches between a rotation transmission state and a rotation cut-off state between the first inner shaft 6M and the third outer shaft 6I. That is, the movable portion 2EI and the fixed portion of the third outer shaft 6I switch between the rotation transmission state and the rotation cut-off state between the shaft 6m of the motor generator MG and the input shaft 11. Therefore, the fixed portion of the movable portion 2EI and the third outer shaft 6I is an example of the third switching mechanism 230. The third switching mechanism 230 is in a rotation transmission state in a state where the movable portion 734 is not connected to the fixed portion of the driven gear 43.

The movable portion 2OR rotates integrally with the second outer shaft 6O. The movable portion 2OR is provided so as to be movable between three positions along the axial direction of the second outer shaft 6O. The three positions include a connection position (meshing position) where the movable portion 2OR meshes with a fixed portion fixed to each of the first inner shaft 6M and the gear 6r, and a blocking position where the movable portion 2OR is separated from the fixed portion ( Separation position, neutral position). The position of the movable portion 2OR is changed by an actuator 83 controlled by the control device 8 (see FIG. 3). The movable part 2OR and the fixed part can constitute a dog clutch, for example. In this case, the movable portion 2OR includes, for example, a sleeve, and the fixed portion includes, for example, a hub that meshes with the sleeve. The dog clutch can be provided with a synchronizer.

可動部2ORおよび第一のインナシャフト6Mの固定部は、第一のインナシャフト6Mと第二のアウタシャフト6Oとの回転伝達状態と回転遮断状態とを切り替える。すなわち、可動部2ORおよび第一のインナシャフト6Mの固定部は、モータジェネレータMGのシャフト6mとホイールWとの回転伝達状態と回転遮断状態とを切り替える。よって、可動部2ORおよび第一のインナシャフト6Mの固定部は、第二の切替機構220の一例である。   The movable portion 2OR and the fixed portion of the first inner shaft 6M switch between a rotation transmission state and a rotation blocking state between the first inner shaft 6M and the second outer shaft 6O. That is, the movable portion 2OR and the fixed portion of the first inner shaft 6M switch between the rotation transmission state and the rotation cutoff state between the shaft 6m of the motor generator MG and the wheel W. Accordingly, the movable portion 2OR and the fixed portion of the first inner shaft 6M are an example of the second switching mechanism 220.

可動部2ORおよびギヤ6rの固定部は、第一のインナシャフト6Mとギヤ6rとの回転伝達状態と回転遮断状態とを切り替えることにより、有段変速部100の変速段5Rに対応した選択機構として機能する。このような可動部2ORに関連した構成により、本実施形態でも、モータジェネレータMGと第一のアウトプットシャフト21との間の回転伝達経路として機能する第二のアウタシャフト6Oを、後進の変速段5Rにおけるアイドラギヤとして共用することができる。   The movable portion 2OR and the fixed portion of the gear 6r are used as a selection mechanism corresponding to the shift stage 5R of the stepped transmission section 100 by switching between the rotation transmission state and the rotation cutoff state of the first inner shaft 6M and the gear 6r. Function. With this configuration related to the movable portion 2OR, the second outer shaft 6O that functions as a rotation transmission path between the motor generator MG and the first output shaft 21 is also used in the reverse shift stage 5R. Can be used as idler gears.

なお、切替部200Bは、ここに開示された例には限定されず、種々の構成として実現されうる。例えば、第三のアウタシャフト6Iのギヤ6iは、直接あるいは他のドリブンギヤを介してインプットシャフト11のドライブギヤと噛み合ってもよい。また、第一の切替機構210、第二の切替機構220、および第三の切替機構230における組み合わせ、すなわち可動部の共用形態は種々に変更されうるし、それぞれ独立であってもよい。また、切替部200Bのスペック(構成や、数、位置、配置、大きさ、ギヤ段数、歯数等)は、種々に変更されうる。   Note that the switching unit 200B is not limited to the example disclosed herein, and can be realized as various configurations. For example, the gear 6i of the third outer shaft 6I may mesh with the drive gear of the input shaft 11 directly or via another driven gear. Moreover, the combination in the 1st switching mechanism 210, the 2nd switching mechanism 220, and the 3rd switching mechanism 230, ie, the shared form of a movable part, can be variously changed, and each may be independent. Further, the specifications (configuration, number, position, arrangement, size, number of gear steps, number of teeth, etc.) of the switching unit 200B can be variously changed.
