Description

本発明は、駆動用電動機と発電用電動機を、ギア比の応用を利用した減速機とで合体させた電動発電機を自動車に搭載し、一充電当たりの航続距離を長くすることを可能にした、電動発電機を搭載した電気自動車に関するものである。  The present invention has a motor generator in which a drive motor and a generator motor are combined with a speed reducer using an application of a gear ratio in a vehicle, thereby enabling a long cruising distance per charge. The present invention relates to an electric vehicle equipped with a motor generator.

近年、環境問題や地球環境保護などの理由から代替燃料が注目されてきているが、従来のハイブリッド自動車や電気自動車などは、電力を使って駆動する電動機と、電力を生み出す発電機は別々になっていた。発電機は、エンジンと直結しているもの（ハイブリッド自動車）が多いので排出ガスが出たり、整備面では電気自動車の範囲とエンジン自動車の範囲の２つを行わなければならなかったり、部品点数が多いなどの問題がある。  In recent years, alternative fuels have attracted attention for reasons such as environmental problems and protection of the global environment. However, conventional hybrid vehicles and electric vehicles have separate electric motors that use electric power and generators that generate electric power. It was. Many generators are directly connected to the engine (hybrid vehicles), so exhaust gas is emitted, and in terms of maintenance, the electric vehicle range and engine vehicle range must be performed, and the number of parts is limited. There are many problems.

電気自動車は、電力を使い加速や定速を行う電動機と、電力を生み出す回生ブレーキで減速を行う電動機は同一で、全てを駆動用電動機で行う。  In an electric vehicle, an electric motor that uses electric power for acceleration and constant speed is the same as an electric motor that decelerates with a regenerative brake that generates electric power, and all is performed by a driving motor.

従来は、駆動輪に出力する側は減速機を介し出力する構造であったが、発電用電動機を設けるという構造はなかった。  Conventionally, the output side to the drive wheels has a structure of outputting via a reduction gear, but there is no structure in which a generator motor is provided.

蓄電方法では、バッテリー（蓄電池）の他にフライホイール蓄電機が発明されているが、これを自動車に搭載するにはフライホイール蓄電機を、床下や車両上部に設置する必要があるが、高齢化社会の現代では乗降が楽で便利なバリアフリーが着目されているので、床下には設置できない。車両上部に設けると、車体のローリングが発生するためスタビライザを必要とし、また、車種によっては高さ制限を超えてしまうなどの規格外になってしまう。  In addition to the battery (storage battery), a flywheel power storage device has been invented in the power storage method, but it is necessary to install the flywheel power storage device under the floor or at the top of the vehicle in order to mount it on a car. In modern society, getting on and off is easy and convenient barrier-free, so it cannot be installed under the floor. If it is provided at the upper part of the vehicle, rolling of the vehicle body occurs, so that a stabilizer is required, and depending on the vehicle model, the height limit is exceeded, which is outside the standard.

電池は技術上、長い距離を走れなかった。しかし、長い距離を走るためには電池を多く搭載しなければならず、重量が増す上に、体積及び空間も大きくなってしまうため、輸送力や運搬能力の面に於いて、中型自動車や大型自動車などの貨物車は、車両自身の重さに加えて積荷があるため、車両総重量を保持しなければならないが、蓄電池やインバータなどが重いので積載量を減らされざるを得なくなる。また、近年の旅客車は、ノンステップバスなどのバリアフリー化改造を施しているものが多く、蓄電池を床下には設置し辛い。観光バスや高速バスは高さ制限があるため、路線バスのように屋根上に蓄電池を設置する事が出来ず、床下には荷物室が設けてあるので難しい。その結果、蓄電池を多く設置する箇所が少ないため不向きとされていた。  The battery was technically unable to run long distances. However, in order to run long distances, many batteries must be installed, which increases weight and volume and space. Therefore, in terms of transportation capacity and capacity, medium-sized cars and large vehicles A freight vehicle such as an automobile has a load in addition to the weight of the vehicle itself, so the total weight of the vehicle must be maintained. However, since the storage battery, the inverter, and the like are heavy, the load capacity has to be reduced. In addition, many passenger cars in recent years have undergone barrier-free modifications such as non-step buses, and it is difficult to install storage batteries under the floor. Sightseeing buses and express buses are limited in height, so it is difficult to install storage batteries on the roof like route buses, and there is a luggage room under the floor. As a result, the number of places where many storage batteries are installed is not suitable.

電気自動車の仲間として、燃料電池自動車やソーラーカーがある。
燃料電池自動車は近年新しく開発されたものだが、燃料電池本体内部に白金を用いており、製造上のコストが抑えにくく、実用するためには車両の構造上の安全性や法的規制緩和などの問題点が多く、燃料は水素を利用するために普及しにくい。
ソーラーカーは、車体の表面に装備するため車の大きさによって発電量が異なる。長距離を走行する場合には、ソーラー及び太陽電池の発電量では補えないので、電池を多く搭載しなくてはならなく、電池の技術と同様の問題が発生していた。Fuel cell vehicles and solar cars are among the electric vehicles.
Fuel cell vehicles have been newly developed in recent years, but platinum is used inside the fuel cell body, making it difficult to reduce manufacturing costs. For practical use, such as structural safety of vehicles and relaxation of legal regulations. There are many problems, and fuel is difficult to spread because it uses hydrogen.
Since the solar car is equipped on the surface of the car body, the amount of power generation varies depending on the size of the car. When traveling over long distances, the amount of power generated by solar and solar cells cannot be compensated, so a large number of batteries must be installed, and problems similar to battery technology have occurred.

これは次のような欠点があった。
従来の電気自動車は電池技術の関係上、あまり長い距離を走る事が出来なかったため、電気自動車を世に普及させるためには充電スタンドを数多く設置する必要があり、インフラ整備にお金が掛かる、電池の部品価格が非常に高価である、長い距離を走るために電池を多く搭載すれば重量が増えてしまうなど反比例してしまい現実的ではなかった。This has the following drawbacks.
Because conventional electric vehicles could not run for long distances due to battery technology, it is necessary to install a lot of charging stations in order to popularize electric vehicles to the world. The parts price is very expensive, and if you install a lot of batteries to run a long distance, the weight will increase and it is not realistic.

発進と停車が高い頻度で繰り返される路線バスや、都市間中距離トラックは燃費が悪く、また、制動回数も多くその殆どが熱エネルギーに変わって停車するのでエネルギーの損失が多かった。  Route buses, which start and stop frequently, and intercity inter-distance trucks have poor fuel efficiency, and the number of times of braking is large, and most of them stop in place of thermal energy, so there is a lot of energy loss.

逆に、発進と停車の頻度が少ない高速バスや観光バス、長距離トラックは、走り始めたら次に停まるまでの距離が長く、電気自動車化されても充電設備が整っていなければならないため、高速道路などの***では運転者を困らせてしまう。  Conversely, high-speed buses, sightseeing buses, and long-distance trucks that start and stop less frequently have long distances until they stop, and charging facilities must be in place even if they are converted to electric vehicles. On a single road such as an expressway, the driver is troubled.

充電に時間が掛かることや距離をあまり走れないということは利用者を困らせてしまう問題がある。
本発明は、これらの欠点を除くためになされたものである。Charging takes time and not being able to run too far can cause problems for users.
The present invention has been made to eliminate these drawbacks.

従来の電気自動車は、加速や定速する時と回生ブレーキを用いて減速する時は同じ電動機で行なっていたが、本発明は加速や定速する時に電力を消費して駆動をし、減速時に充電残量がＧ２値以下の際、回生ブレーキによって発電をする駆動用電動機と、走行中に充電残量がＧ１値以下になった際に発電をして電力を生み出すための発電用電動機を別に設ける。
それを減速機との一体構造にし、駆動用電動機は走行と回生ブレーキ用に、発電用電動機は発電用として別々に制御することにした。
電動発電機は減速機を設けているので、ギア比を応用することにより駆動用電動機からの回転速度が低くなり、発電時の抵抗力（回転損失）が発生しても走行に支障がないような構造になっている。Conventional electric vehicles use the same motor when accelerating or decelerating and decelerating using a regenerative brake, but the present invention consumes electric power when accelerating or decelerating, and drives when decelerating. Separately, a drive motor that generates power by regenerative braking when the remaining charge is below the G2 value, and a generator motor that generates power by generating electricity when the remaining charge is below the G1 value during travel Provide.
We decided to make it an integral structure with the speed reducer, and separately control the drive motor for running and regenerative braking, and the generator motor for power generation.
Since the motor generator is equipped with a reduction gear, the rotation speed from the drive motor is reduced by applying the gear ratio, so that there is no hindrance to running even if resistance force (rotation loss) occurs during power generation. It has a simple structure.

この電動発電機は、インホイールモータ駆動タイプでは、駆動用電動機と発電用電動機、減速機が直列に連結する構造（シリーズ構造）にし、エンジンと置き換える駆動タイプでは、同一の減速機に駆動用電動機と発電用電動機が並んで連結する構造（パラレル構造）にしたので小型化が可能である。  In the in-wheel motor drive type, this motor generator has a structure in which a drive motor, a generator motor, and a reduction gear are connected in series (series structure). In a drive type that replaces the engine, the drive motor is connected to the same reduction gear. Since the generator motor and the generator motor are connected side by side (parallel structure), downsizing is possible.

また、後者は開発されている既存の電動機を用いることが出来るので、新しく電動機を開発する手間を省くことが出来ることと、既存の車両を電気自動車へと改造することも容易である。  In addition, since the latter can use an existing motor that has been developed, it is possible to save time and effort to develop a new motor and to easily convert an existing vehicle into an electric vehicle.

二輪車や軽自動車、普通自動車、一部の中型自動車に於いてはエンジンと同程度の設置スペースで済み、中型自動車や大型自動車、特定大型自動車、特殊自動車、牽引自動車（トラクタ）に於いてはエンジンよりも小さい設置スペースで済むので軽量化も可能になる。
軽量化が可能になると消費電力も減少し、航続距離に影響する。For motorcycles, light vehicles, ordinary vehicles, and some medium-sized vehicles, the installation space is about the same as the engine. For medium-sized vehicles, large vehicles, specified large vehicles, special vehicles, and traction vehicles (tractors), the engine is used. Lighter weight is also possible because a smaller installation space is required.
If weight reduction is possible, power consumption will decrease, and the cruising range will be affected.

この電動発電機は、駆動用電動機から発する力は減速機を介し出力し、その出力された力は発電用電動機へ、駆動輪へと出力されていく構造で、発電用電動機は走行中に充電残量がＧ１値以下になったときに発電する仕組みである。  This motor generator has a structure in which the power generated from the drive motor is output via the speed reducer, and the output force is output to the generator motor and the drive wheels. This is a mechanism for generating power when the remaining amount becomes the G1 value or less.

発進と停車が高い頻度で繰り返される路線バスや、都市間中距離トラックは停車回数が多く、回生ブレーキによる発電回数が多い。
また走行回数も多いことから、発電用電動機での発電も頻繁になり一充電当たりの航続距離が長くなる。Route buses that frequently start and stop, and intercity inter-distance trucks have many stops and many regenerative brakes generate power.
In addition, since the number of travels is large, power generation by the generator motor is frequent, and the cruising distance per charge becomes long.

次に、発進と停車の頻度が少ない高速バスや観光バス、長距離トラックは駆動用電動機で行う回生ブレーキでの発電回数は少ないものの、発電用電動機での発電は多く、長い距離が走れることを見込める。  Next, high-speed buses, sightseeing buses, and long-distance trucks that start and stop less frequently have fewer power generations with regenerative brakes that are driven by drive motors. I can expect.

以下、本発明の実施の形態について図面を用いて説明する。
駆動用電動機１と発電用電動機２は、減速機４を介して連結させた電動発電機７を自動車に設け、駆動用電動機１の動力を減速機４に介して駆動輪の他に発電用電動機２へも減速して伝達し、発電用電動機２は図９より走行中に充電残量がＧ１値以下になった際に発電し、駆動用電動機１では、図１０より制動時に充電残量がＧ２値以下になった際に回生ブレーキを用いて電力を生み出し、一充電の航続距離を長くする事を可能にした電動発電機を搭載した電気自動車である。Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The drive motor 1 and the generator motor 2 are provided in a vehicle with a motor generator 7 connected via a speed reducer 4, and the power of the drive motor 1 is generated in addition to the drive wheels via the speed reducer 4. 9, the generator motor 2 generates power when the remaining charge becomes G1 or less during travel from FIG. 9, and the drive motor 1 has the remaining charge during braking from FIG. It is an electric vehicle equipped with a motor generator that generates power using a regenerative brake when the G2 value or less is reached, and makes it possible to extend the cruising range of one charge.

本発明は、以上のような構成でこれを使用するときは、図４のように、太い実線の電気の流れで示す蓄電池８からインバータ９を介して駆動用電動機１へ、太い破線の信号の流れが示すアクセルペダルセンサーの踏み込み量に応じて送電され、回転軸５を回転させ、減速機４を伝わって駆動力を駆動輪へ出力し、加速や定速を行う。
このとき同時に、駆動用電動機１の回転軸５から細い破線が示す通り減速機４を伝達し、発電用電動機２の回転軸５に動力が伝わり回転する。
発電は、充電残量がＧ１値以下になった場合、走行中でもギア比の応用により走行に支障がなく発電をする。これにより、発電量を少しでも多くし航続距離を長くする。When the present invention is used in the above-described configuration, as shown in FIG. 4, a thick broken line signal is transferred from the storage battery 8 indicated by a thick solid line electric current to the driving motor 1 via the inverter 9 as shown in FIG. Power is transmitted according to the amount of depression of the accelerator pedal sensor indicated by the flow, the rotating shaft 5 is rotated, the driving force is output to the driving wheel through the speed reducer 4, and acceleration and constant speed are performed.
At the same time, the speed reducer 4 is transmitted from the rotating shaft 5 of the driving motor 1 as indicated by a thin broken line, and the power is transmitted to the rotating shaft 5 of the generator motor 2 to rotate.
In the case of power generation, when the remaining charge amount is equal to or less than the G1 value, power generation is performed without any trouble in traveling by application of the gear ratio even during traveling. As a result, the power generation amount is increased as much as possible, and the cruising distance is increased.

発明の効果The invention's effect

電動発電機７は、駆動用電動機１と発電用電動機２、減速機４が一体化し、車種によってエンジンより小さくなるか、同程度のスペースで設置する事が出来る。
これは、車内の低床を目的とする自動車に搭載する場合、図５と図６のようにホイール内に電動発電機７を埋め込むインホイールモータ駆動タイプを、トルクを重視する自動車に搭載する場合は図７と図８のようにエンジンと同様に電動発電機７を変速機１２に接続することにより、電動機特有の、始動時から発揮する最大トルクを変速機１２によって回転数をある範囲で固定し発揮トルクを保持することが出来る。
このように、目的や要求にあった車両構造や性能、機器の配置をすることが容易になる。The motor generator 7 is integrated with the drive motor 1, the generator motor 2, and the speed reducer 4, and may be smaller than the engine or installed in a similar space depending on the vehicle type.
This is the case where the in-wheel motor drive type in which the motor generator 7 is embedded in the wheel as shown in FIG. 5 and FIG. 7 and 8, the motor generator 7 is connected to the transmission 12 like the engine, and the maximum torque exhibited from the start, which is unique to the motor, is fixed by the transmission 12 within a certain range. It is possible to maintain the full torque.
Thus, it becomes easy to arrange the vehicle structure, performance, and equipment that meet the purpose and requirements.

図３は走行イメージしたときの電流、充電残量、速度、時間を示したグラフである。グラフの説明をする。
上グラフの実線は駆動用電動機を、二点鎖線は発電用電動機の電流値変動を表わす。
下グラフの実線は速度を、一点鎖線は充電残量を示し、破線Ｇ１は発電用電動機の発電開始時期を、破線Ｇ２は駆動用電動機の発電終了時期（回生ブレーキ中止時期）を示す。FIG. 3 is a graph showing current, remaining charge, speed, and time when driving. Explain the graph.
The solid line in the upper graph represents the drive motor, and the two-dot chain line represents the current value fluctuation of the generator motor.
In the lower graph, the solid line indicates the speed, the alternate long and short dash line indicates the remaining charge, the broken line G1 indicates the power generation start timing of the generator motor, and the broken line G2 indicates the power generation end timing (regenerative brake stop timing) of the drive motor.

上グラフを見る限り、制動時は駆動用電動機が回生ブレーキを掛けるために発生電流が負になるのがわかり、またＧ１値以下になった際には発電用電動機は発電していることもわかる。そのときに下グラフでは、発電用電動機の起動中は充電残量の減り方が弱くなる。  As can be seen from the graph above, it can be seen that the generated electric current is negative because the driving motor applies regenerative braking during braking, and that the generator motor is generating power when it falls below the G1 value. . At that time, in the lower graph, the way to decrease the remaining charge becomes weak while the generator motor is activated.

また、従来の自動車は、冷却系統のポンプや空調機器などの補機類は、エンジンから出力された動力をベルト等によって伝達されて各機器を回転させていたが、電気自動車は速度０の時は電動機の回転速度も０になるため、これらを動かす補機駆動ユニット１１を設けることで従来の自動車と同じ機能性を持つ事が可能になる。  In addition, in conventional vehicles, auxiliary equipment such as cooling system pumps and air conditioners transmit power output from the engine by a belt or the like to rotate each device, but electric vehicles have zero speed. Since the rotation speed of the electric motor is also zero, it is possible to have the same functionality as a conventional automobile by providing an accessory drive unit 11 that moves these motors.

発電用電動機２で主に発電を行うが、これは駆動用電動機１の回転軸６より、発電用電動機２の減速機４を介して回転が伝わる構造のため、発電時の抵抗力による影響は少ない。
充電残量がＧ１値以下になった場合は、走行中でもギア比の応用により走行に支障がない程度で発電するため発電量も増加し、一充電の航続距離が長くすることが可能になる。
また、これは電動機を用いているので、排出ガス及び騒音等による環境への影響を抑制でき、地球環境保護並びに大気汚染防止にも貢献できる。The power generation motor 2 mainly generates power. This is because the rotation is transmitted from the rotating shaft 6 of the drive motor 1 via the speed reducer 4 of the power generation motor 2, and the influence of the resistance force during power generation is Few.
When the remaining charge is equal to or less than the G1 value, the power generation amount is increased and the cruising distance of one charge can be increased because power generation is performed to the extent that there is no hindrance to travel by application of the gear ratio even during travel.
In addition, since this uses an electric motor, it is possible to suppress the influence on the environment due to exhaust gas and noise, and to contribute to the protection of the global environment and the prevention of air pollution.

他にも、電気自動車の殆どの箇所が電気を用いたコードでの信号による伝送で制御しており、これを利用し車両の集中管理や故障箇所の診断等も容易となり、メンテナンスフリー化も可能と言える。
整備性に関しては燃料が電気のため、フューエルフィルタやゴーズフィルタなどが不要で、エンジンオイルもないのでフィルタレス化を図れ、点検でも容易で休車時間を縮めることが可能である。In addition, almost all parts of the electric vehicle are controlled by transmission with signals using electricity cords, which makes it easy to centrally manage vehicles and diagnose faults, making maintenance-free. It can be said.
In terms of maintainability, the fuel is electricity, so there is no need for a fuel filter or goose filter, and there is no engine oil, so there is no need for a filter.
