以下、図面を参照しながら、実施形態に係るハイブリッド駆動装置について説明する。   Hereinafter, a hybrid drive device according to an embodiment will be described with reference to the drawings.

図１は、第１の実施形態に係る圧縮空気式のハイブリッド駆動装置を概略的に示す平面図。本実施形態は、例えば、鉄道車両の駆動台車に設置されたハイブリッド駆動装置を示している。   FIG. 1 is a plan view schematically showing a compressed air type hybrid drive apparatus according to the first embodiment. This embodiment shows, for example, a hybrid drive device installed on a drive carriage of a railway vehicle.

駆動台車１０は、台車本体１１とこの台車本体に支持された複数、例えば、２本の車軸１２、１４を有している。車軸１２、１４は、台車本体１１に回転自在に支持され、各車軸の両端部には、車輪１６が取り付けられている。これらの車輪１６は、図示しないレール上に載置される。一方の車軸１２は、駆動車軸として構成され、以下に述べる圧縮空気式のハイブリッド駆動装置から駆動力を受けて車輪１６を駆動する。   The drive carriage 10 has a carriage body 11 and a plurality of, for example, two axles 12 and 14 supported by the carriage body. The axles 12 and 14 are rotatably supported by the carriage body 11, and wheels 16 are attached to both ends of each axle. These wheels 16 are placed on a rail (not shown). One axle 12 is configured as a drive axle, and drives the wheels 16 by receiving a driving force from a compressed-air hybrid drive device described below.

圧縮空気式のハイブリッド駆動装置１８は、主駆動装置としての主電動機２０、および主電動機に電力を供給するインバータ２２を有している。インバータ２２は、架線２４から例えば交流電流を受け、直流電流に変換して主電動機２０に供給する。主電動機２０は、ギア列（変速ギア）２６および電磁クラッチ２８を介して駆動車軸１２に駆動力を伝達する。   The compressed air type hybrid drive device 18 includes a main motor 20 as a main drive device and an inverter 22 that supplies electric power to the main motor. The inverter 22 receives, for example, alternating current from the overhead wire 24, converts it into direct current, and supplies it to the main motor 20. The main motor 20 transmits driving force to the driving axle 12 via a gear train (transmission gear) 26 and an electromagnetic clutch 28.

ハイブリッド駆動装置１８は、コンプレッサ３０、およびコンプレッサにより圧縮された空気を蓄える蓄圧部として機能するエアタンク３２を備えている。図１および図２に示すように、コンプレッサ３０は、例えば、シリンダ３４と、シリンダ内に摺動自在に設けられたピストン３６と、コンロッド３７を介してピストンに連結されたクランク軸３８と、を有している。シリンダ３４内の圧縮室は、吸排気を制御する電磁弁４０を介してエアタンク３２に接続されている。クランク軸３８は、例えば、トルクを変換するトルクコンバータ４２あるいは変速ギア列、電磁クラッチ４４を介して駆動車軸１２に接続されている。   The hybrid drive device 18 includes a compressor 30 and an air tank 32 that functions as a pressure accumulating unit that stores air compressed by the compressor. As shown in FIGS. 1 and 2, the compressor 30 includes, for example, a cylinder 34, a piston 36 slidably provided in the cylinder, and a crankshaft 38 connected to the piston via a connecting rod 37. Have. The compression chamber in the cylinder 34 is connected to the air tank 32 via an electromagnetic valve 40 that controls intake and exhaust. The crankshaft 38 is connected to the drive axle 12 via, for example, a torque converter 42 that converts torque, a transmission gear train, and an electromagnetic clutch 44.

主電動機２０、インバータ２２、電磁クラッチ２８、電磁弁４０、電磁クラッチ４４は、制御装置５０に接続され、この制御装置５０により動作が制御される。   The main motor 20, the inverter 22, the electromagnetic clutch 28, the electromagnetic valve 40, and the electromagnetic clutch 44 are connected to the control device 50, and the operation is controlled by the control device 50.

上記のように構成されたハイブリッド駆動装置１８を備えた車両において、通常の走行時には、図１に示すように、架線２４より電力供給を受けてインバータ２２により主電動機２０が駆動される。この通常走行時、制御装置５０は、電磁クラッチ２８をオンとし、主電動機２０から駆動力がギア列２６および電磁クラッチ２８を介して駆動車軸１２に伝達され、車輪１６が駆動される。この間、制御装置５０は、電磁クラッチ４４をオフとし、駆動車軸１２とコンプレッサ３０とが切り離されている。   In a vehicle equipped with the hybrid drive device 18 configured as described above, during normal traveling, the main motor 20 is driven by the inverter 22 upon receiving power supply from the overhead wire 24 as shown in FIG. During this normal travel, the control device 50 turns on the electromagnetic clutch 28, the driving force is transmitted from the main motor 20 to the drive axle 12 via the gear train 26 and the electromagnetic clutch 28, and the wheels 16 are driven. During this time, the control device 50 turns off the electromagnetic clutch 44 and the drive axle 12 and the compressor 30 are disconnected.

車両の制動時、図３に示すように、制御装置５０は、電磁クラッチ４４をオンとして駆動車軸１２とコンプレッサ３０とを接続し、駆動車軸１２の回転エナルギーによりコンプレッサ３０を作動させる。同時に、制御装置５０は、電磁弁４０を所定のタイミングで開閉し、コンプレッサ３０により圧縮された空気をエアタンク３２へ送り蓄える。   When the vehicle is braked, as shown in FIG. 3, the control device 50 turns on the electromagnetic clutch 44 to connect the drive axle 12 and the compressor 30, and operates the compressor 30 by the rotational energy of the drive axle 12. At the same time, the control device 50 opens and closes the electromagnetic valve 40 at a predetermined timing, and sends the air compressed by the compressor 30 to the air tank 32 and stores it.

なお、車両の制動時、電磁クラッチ２８は制御装置５０によりオンあるいはオフに切り換えられる。電磁クラッチ２８をオンとした場合、制動時の回生エネルギーが主電動機２０、インバータ２２を介して架線２４に送られ、この架線２４を通して、他の鉄道車両で利用される。また、電磁クラッチ２８をオフとした場合は、駆動車軸１２からコンプレッサ３０によりエアタンク３２のみに蓄えられる。   The electromagnetic clutch 28 is switched on or off by the control device 50 when the vehicle is braked. When the electromagnetic clutch 28 is turned on, the regenerative energy at the time of braking is sent to the overhead wire 24 via the main motor 20 and the inverter 22, and is used by other railway vehicles through this overhead wire 24. Further, when the electromagnetic clutch 28 is turned off, it is stored only in the air tank 32 from the drive axle 12 by the compressor 30.

図４に示すように、車両の起動時あるいは加速時、制御装置５０により電磁クラッチ４４をオンするとともに、電磁弁４０を所定のタイミングで開閉することにより、エアタンク３２に蓄えられた圧縮空気は、コンプレッサ３０の加圧室に供給されてピストン３６を駆動し、この駆動力をギア列および電磁クラッチ４４を介して駆動車軸１２に伝達する。これにより、蓄えられた圧縮空気により車両の駆動をアシストする。車両が所望の速度に達した時点で、あるいは、エアタンク３２内の圧縮空気が無くなった時点で、制御装置５０は電磁クラッチ４４をオフとして、コンプレッサ３０による駆動アシストを停止する。   As shown in FIG. 4, when starting or accelerating the vehicle, the control device 50 turns on the electromagnetic clutch 44 and opens and closes the electromagnetic valve 40 at a predetermined timing, so that the compressed air stored in the air tank 32 is The piston 36 is driven by being supplied to the pressurizing chamber of the compressor 30, and this driving force is transmitted to the drive axle 12 via the gear train and the electromagnetic clutch 44. Thereby, the driving of the vehicle is assisted by the stored compressed air. When the vehicle reaches a desired speed or when the compressed air in the air tank 32 runs out, the control device 50 turns off the electromagnetic clutch 44 and stops the drive assist by the compressor 30.

以上のように構成された圧縮空気式のハイブリッド駆動装置によれば、車両の制動時のエネルギーをエアコンプレッサにより圧縮空気の形で蓄え、この回生エネルギーを活用することで停止、加速時のエネルギーロスを減少させることができる。電磁クラッチおよびギア列により主電動機の接続、分離、並びに、コンプレッサの接続、分離を制御することにより、エネルギーの回生と駆動を効率よく行うことができる。これにより、希少資源を使用し、保護が複雑になる二次電池を使用した装置と比較して、環境負荷が少なく、簡易で高効率なハイブリッド駆動装置が得られる。   According to the compressed air type hybrid drive apparatus configured as described above, the energy at the time of braking of the vehicle is stored in the form of compressed air by an air compressor, and the energy loss at the time of stopping and accelerating by using this regenerative energy. Can be reduced. By controlling the connection and separation of the main motor and the connection and separation of the compressor by the electromagnetic clutch and the gear train, it is possible to efficiently regenerate and drive the energy. As a result, a simple and highly efficient hybrid drive device can be obtained with less environmental load compared to a device using a secondary battery that uses rare resources and is complicated to protect.

なお、ハイブリッド駆動装置において、主駆動装置は電動機に限らず、レシプロエンジン、ディーゼルエンジン等の内燃機関を用いても良い。また、回生エネルギーを蓄える蓄圧部は、エアータンクに限らず、ばね、フライホイール等を用いることもできる。   In the hybrid drive device, the main drive device is not limited to an electric motor, and an internal combustion engine such as a reciprocating engine or a diesel engine may be used. Further, the pressure accumulating unit that stores regenerative energy is not limited to an air tank, and a spring, a flywheel, or the like can be used.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。例えば、ハイブリッド駆動装置は、鉄道車両に限らず、自動車等にも適用可能である。   Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
