Between the first-speed driven gear G1out and the second-speed driven gear G2out, there is idleness allowing relative rotation between the first-speed driven gear G1out and the output shaft Output, and between the second-speed driven gear G2out and the output shaft Output.

以下、噛合した駆動ギヤと従動ギヤの一組をギヤ列と記載し、例えば、１速駆動ギヤＧ１ｉｎと１速従動ギヤＧ１ｏｕｔの組み合わせを１速ギヤ列と記載する。５速ギヤ列には、モータ４０のモータシャフトＭｓに設けられたモータ駆動ギヤＭｉｎが接続されている。実施例１の場合、モータ駆動ギヤＭｉｎは、５速駆動ギヤＧ５ｉｎと常時噛み合う。   Hereinafter, one set of the meshed drive gear and driven gear is referred to as a gear train, and for example, a combination of the first-speed drive gear G1in and the first-speed driven gear G1out is referred to as a first-speed gear train. A motor drive gear Min provided on the motor shaft Ms of the motor 40 is connected to the fifth gear train. In the case of the first embodiment, the motor drive gear Min always meshes with the fifth speed drive gear G5in.

１速ギヤ列から４速ギヤ列までの複数のギヤ列は、変速機ケース１内に収納されている。言い換えると、５速ギヤ列は、変速機ケース１の外側に露出するように設けられている。変速機ケース１の５速ギヤ列側の壁部には、入力軸Ｉｎｐｕｔを回転可能に支持するベアリング１１と、出力軸Ｏｕｔｐｕｔを回転可能に支持するベアリング１２が設けられている。モータ４０は、モータケース４内に収納されており、変速機ケース１の５速ギヤ列側に取り付けられる。モータケース４には、モータシャフトＭｓを回転可能に支持するベアリング４１，４２が設けられている。モータ駆動ギヤＭｉｎが噛み合う５速ギヤ列は、サイドカバー５内に収納されており、モータケース４の５速ギヤ列側に取り付けられる。変速機ケース１のエンジン側は開口しており、この開口を閉塞するハウジング２が取り付けられる。ハウジング２には、入力軸Ｉｎｐｕｔを回転可能に支持するベアリング２１と、出力軸Ｏｕｔｐｕｔを回転可能に支持するベアリング２２が設けられている。尚、説明のため、図１の変速機ケース１，ハウジング２，モータケース４，サイドカバー５の間には隙間を設けて記載しているが、これらのケースやハウジングは、ボルト等により隙間なく固定される。   A plurality of gear trains from the first gear train to the fourth gear train are housed in the transmission case 1. In other words, the fifth gear train is provided so as to be exposed outside the transmission case 1. A bearing 11 that rotatably supports the input shaft Input and a bearing 12 that rotatably supports the output shaft Output are provided on a wall portion of the transmission case 1 on the fifth gear train side. The motor 40 is housed in the motor case 4 and attached to the fifth speed gear train side of the transmission case 1. The motor case 4 is provided with bearings 41 and 42 that rotatably support the motor shaft Ms. The fifth speed gear train with which the motor drive gear Min meshes is housed in the side cover 5 and is attached to the motor case 4 on the fifth speed gear train side. The engine side of the transmission case 1 is open, and a housing 2 for closing the opening is attached. The housing 2 is provided with a bearing 21 that rotatably supports the input shaft Input and a bearing 22 that rotatably supports the output shaft Output. For the sake of explanation, a gap is provided between the transmission case 1, the housing 2, the motor case 4, and the side cover 5 in FIG. Fixed.

１速走行時には、第１シンクロ機構Ｓ１により１速従動ギヤＧ１ｏｕｔと出力軸Ｏｕｔｐｕｔとを固定状態とし、第２シンクロ機構Ｓ２を中立位置とする。このとき、モータ４０のトルクを出力軸Ｏｕｔｐｕｔに伝達する際には、第３シンクロ機構Ｓ３を使用する低回転モードと、第４シンクロ機構Ｓ４を使用する高回転モードとを有する。低回転モードの場合には、第３シンクロ機構Ｓ３により５速駆動ギヤＧ５ｉｎと入力軸Ｉｎｐｕｔとを固定状態とし、第４シンクロ機構Ｓ４を中立位置とし、モータ駆動ギヤＭｉｎから５速駆動ギヤＧ５ｉｎを介して入力軸Ｉｎｐｕｔにトルクを付与する。一方、高回転モードの場合には、第４シンクロ機構Ｓ４により５速従動ギヤＧ５ｏｕｔと出力軸Ｏｕｔｐｕｔとを固定状態とし、第３シンクロ機構Ｓ３を中立位置とする。これにより、モータ４０のトルクは、モータ駆動ギヤＭｉｎから５速駆動ギヤＧ５ｉｎを介して５速従動ギヤＧ５ｏｕｔに伝達され、出力軸Ｏｕｔｐｕｔにトルクを付与する。他の変速段にあっても、同様の制御によりモータトルクを用いたハイブリッド走行を実現する。   During first-speed running, the first-speed driven gear G1out and the output shaft Output are fixed by the first synchronization mechanism S1, and the second synchronization mechanism S2 is set to the neutral position. At this time, when transmitting the torque of the motor 40 to the output shaft Output, there are a low rotation mode using the third synchronization mechanism S3 and a high rotation mode using the fourth synchronization mechanism S4. In the case of the low rotation mode, the fifth-speed drive gear G5in and the input shaft Input are fixed by the third synchronization mechanism S3, the fourth synchronization mechanism S4 is in the neutral position, and the fifth-speed drive gear G5in is shifted from the motor drive gear Min to the fifth-speed drive gear G5in. Torque is applied to the input shaft Input via the input shaft. On the other hand, in the high rotation mode, the fifth-speed driven gear G5out and the output shaft Output are fixed by the fourth synchronization mechanism S4, and the third synchronization mechanism S3 is set to the neutral position. Thus, the torque of the motor 40 is transmitted from the motor drive gear Min to the fifth speed driven gear G5out via the fifth speed drive gear G5in, and applies torque to the output shaft Output. The hybrid control using the motor torque is realized by the same control even at other shift speeds.

ここで、実施例１の変速機ＴＭのケース類の構成について説明する。近年、ハイブリッド車両に対するニーズが高まり、動力源としてエンジンのみを備えたエンジン車両に、モータを追加してハイブリッド車両とすることが望まれている。平行二軸型常時噛み合い変速機の場合、いずれかのギヤ列にモータの駆動ギヤを噛合させ、ハイブリッド車両とする提案がなされている。この場合、ギヤ列等の変速機内の構成要素の共用化を図ることができる。しかしながら、モータを追加した際に、エンジン車両とハイブリッド車両との間で変速機ケースの形状が全く異なると、製造コストの増大を招くという問題がある。そこで、実施例１では、変速機ケース１についても極力共用化を果たすことが可能な構成を採用した。   Here, the configuration of the cases of the transmission TM of the first embodiment will be described. In recent years, the need for hybrid vehicles has increased, and it has been desired to add a motor to an engine vehicle equipped with only an engine as a power source to form a hybrid vehicle. In the case of a parallel two-shaft type constant mesh transmission, there has been proposed a hybrid vehicle in which a drive gear of a motor is meshed with one of gear trains. In this case, components in the transmission such as the gear train can be shared. However, if the shape of the transmission case is completely different between the engine vehicle and the hybrid vehicle when the motor is added, there is a problem that the manufacturing cost is increased. Therefore, in the first embodiment, a configuration is adopted in which the transmission case 1 can be shared as much as possible.

図２は、実施例１のハイブリッド車両用変速機とエンジン車両用変速機との共用化部分を表す概略図、図３は実施例１の共用化部分を用いたエンジン車両用変速機の概略断面図である。図２に示すように、ハイブリッド車両用変速機とエンジン車両用変速機とは、変速機ケース１と、ハウジング２と、変速機ケース１内に収容される複数のギヤ列を共用化する。加えて、変速機ケース１の外側に設けられたモータ駆動ギヤＭｉｎが噛み合う５速駆動ギヤＧ５ｉｎと第３シンクロ機構Ｓ３とを共用化する。更に、変速機ケース１とエンジンとの間に設けられるハウジング２を共用化する。以下、これら共用化した部分を共用化モジュールと記載する。   FIG. 2 is a schematic diagram illustrating a shared portion of the transmission for a hybrid vehicle and the transmission for an engine vehicle according to the first embodiment. FIG. 3 is a schematic cross section of the transmission for an engine vehicle using the shared portion of the first embodiment. FIG. As shown in FIG. 2, the transmission for a hybrid vehicle and the transmission for an engine vehicle share a transmission case 1, a housing 2, and a plurality of gear trains housed in the transmission case 1. In addition, the fifth-speed drive gear G5in, which meshes with the motor drive gear Min provided outside the transmission case 1, and the third synchronization mechanism S3 are shared. Further, the housing 2 provided between the transmission case 1 and the engine is shared. Hereinafter, these shared portions are referred to as shared modules.

これにより、エンジン車両用変速機を構成する際には、共用化モジュールの出力軸Ｏｕｔｐｕｔに５速従動ギヤＧ５ｏｕｔを取り付け、サイドカバー３を取り付ける。一方、ハイブリッド車両用変速機を構成する際には、共用化モジュールの出力軸Ｏｕｔｐｕｔに５速従動ギヤＧ５ｏｕｔと第４シンクロ機構Ｓ４とを取り付け、モータ４０を収納したモータケース４を変速機ケース１に取り付けると共に、モータケース４にサイドカバー５を取り付ける。このように、モータ駆動ギヤＭｉｎが噛み合うギヤ列（実施例１の場合は５速ギヤ列）のみが変速機ケース１の外側に設置し、他のギヤ列は変速機ケース１内に収納する共用化モジュールを構成することで、変速機ケース１に収納される大部分を共用化できる。また、変速機ケース１にベアリング１１，１２を設け、ハウジング２にベアリング２１，２２を設けたことで、共用化部分をモジュール化できる。仮に、ベアリングをサイドカバー側に設けると、エンジン車両用変速機を製造するか、ハイブリッド車両用変速機を製造するかが決定されるまで変速機を組み上げることができない。これに対し、実施例１の場合、共用化部分をモジュール化することで、エンジン車両用変速機を製造するか、ハイブリッド車両用変速機を製造するかが決定される前であっても、モジュール化部分を製造できる。   Thus, when configuring the transmission for the engine vehicle, the fifth speed driven gear G5out is attached to the output shaft Output of the shared module, and the side cover 3 is attached. On the other hand, when configuring a transmission for a hybrid vehicle, a fifth speed driven gear G5out and a fourth synchronization mechanism S4 are attached to the output shaft Output of the shared module, and the motor case 4 housing the motor 40 is replaced with the transmission case 1 And the side cover 5 is attached to the motor case 4. As described above, only the gear train (the fifth gear train in the case of the first embodiment) with which the motor drive gear Min meshes is installed outside the transmission case 1, and the other gear trains are housed in the transmission case 1. By configuring the integrated module, most of the components housed in the transmission case 1 can be shared. Further, by providing the transmission case 1 with the bearings 11 and 12 and the housing 2 with the bearings 21 and 22, the shared part can be modularized. If the bearings are provided on the side cover side, the transmission cannot be assembled until it is determined whether to manufacture a transmission for an engine vehicle or a transmission for a hybrid vehicle. On the other hand, in the case of the first embodiment, by modularizing the shared portion, even before it is determined whether to manufacture the transmission for the engine vehicle or the transmission for the hybrid vehicle, the module can be used. Parts can be manufactured.

以上説明したように、実施例にあっては下記に列挙する作用効果が得られる。

Therefore, the transmission case 1 can be shared between the engine vehicle and the hybrid vehicle in addition to the components in the transmission, and the manufacturing cost can be reduced.

（２）変速機ケース１とエンジンとの間にハウジング２を有し、入力軸Ｉｎｐｕｔ及び出力軸Ｏｕｔｐｕｔをハウジング２に回転可能に支持する第２のベアリング２１，２２を備えた。

Therefore, by providing the bearings 21 and 22 in a configuration shared between the transmission for the engine vehicle and the transmission for the hybrid vehicle, the shared portion can be modularized, and which transmission is manufactured is determined. The modularized part can be manufactured even before the process.
