Description
【０００１】[0001]
本考案は、前後駆動輪を交流電動機により駆動して走行する電気自動車の推進 装置に関する。 The present invention relates to a propulsion device for an electric vehicle that drives the front and rear drive wheels by an AC electric motor for traveling.
【０００２】[0002]
内燃機関を駆動源とする自動車の内、ガソリンや軽油を燃料とするものは、燃 料の保存や輸送等の面で取扱いが容易である反面、空気の汚染や騒音公害等の環 境破壊を引き起こすという問題点を有し、液化天然ガスを燃料とする自動車は、 空気の汚染は少ない反面、ガソリン等と比較して燃料の爆発の危険率が大きいた め取扱いが不便であるという問題点を有しており、また、何れの燃料も採取可能 な量は有限であり、いずれは自然に枯渇する等の多くの問題点を有していた。 これに対し、電動力によって駆動し走行する電気自動車は、空気汚染の心配が なく、走行も静かで、蓄電源の確保も容易であるという利点を有している。 Among automobiles driven by an internal combustion engine, those that use gasoline or light oil as fuel are easy to handle in terms of fuel storage and transportation, but on the other hand, they cause environmental damage such as air pollution and noise pollution. Cars that use liquefied natural gas as fuel have less air pollution, but are more inconvenient to handle because they have a higher risk of fuel explosion than gasoline. In addition, the amount of any fuel that can be collected is finite, and there were many problems such as the exhaustion of each fuel naturally. On the other hand, electric vehicles that are driven by electric power have the advantages that they do not have to worry about air pollution, run quietly, and can easily secure a storage power source.
【０００３】[0003]
しかし、このような電気自動車においても種々の問題がある。すなわち、駆動 輪の駆動を直流電動機を利用して行わせる場合には、電流値を変化させて速度制 御するため電流損失が大きくなって長時間走行することができず、一方、長時間 走行し得るように蓄電池の容量を大きくすると、蓄電池が大重量となって電気自 動車の走行性能を低下させ、而も蓄電池が大型化するため設置空間の確保が難し く、勢い車内空間を狭くせざるを得ない等である。 また、走行中に蓄電池の充電電流の無駄な放出を避け、節約して用いるため、 蓄電源の有効利用を高める必要もある。 However, such electric vehicles also have various problems. In other words, when the drive wheels are driven using a DC motor, the current value is changed to control the speed, which causes a large current loss and makes it impossible to travel for a long time. If the capacity of the storage battery is increased so that the storage battery becomes heavy, the running capacity of the electric vehicle will deteriorate and the storage battery will become large, making it difficult to secure installation space and reducing the interior space of the vehicle. There is no choice but to do so. In addition, it is necessary to increase the effective use of the storage power source in order to avoid wasteful discharge of the charging current of the storage battery while traveling and use it in a conserved manner.
【０００４】 本考案は、従来の技術の有するこのような問題点に鑑みてなされたものであり 、その目的とするところは、駆動輪の駆動を交流電動機を利用して行ない、走行 中も蓄電池に充電可能となし、蓄電源の有効利用を図った電気自動車の推進装置 を提供することにある。The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to drive the drive wheels by using an AC electric motor and to charge the storage battery while traveling. It is to provide a propulsion device for an electric vehicle that is not rechargeable and that effectively uses a storage power source.

上記課題を解決するため本考案の電気自動車の推進装置は、蓄電池１と電気的 に接続する直流電動機２の駆動軸を交流発電機３の回転軸に連結し、当該交流発 電機３の起電力が供給される負荷端子に蓄電池１に接続する整流器４と、交流電 動機５の交流側回路とを電気的に接続し、上記起電力で交流電動機５を駆動する と共に当該起電力の一部を整流器４を介して蓄電池１に充電し、交流電動機５の 駆動出力がギア変速機６を介して前後の駆動輪に伝達されるようにした構成を具 備している。 本考案の電気自動車の推進装置は、前後各駆動輪に対応させて四台の交流電動 機５を配設すると共に、各々別個に駆動し得るように設けることが好ましい。こ の場合、始動時は一台の交流電動機５を駆動し、始動後は路面状況に応じて一台 又は複数台の交流電動機５を駆動して走行するように設けることがより好ましい 。 In order to solve the above problems, the propulsion device for an electric vehicle according to the present invention is configured such that a drive shaft of a DC motor 2 electrically connected to a storage battery 1 is connected to a rotation shaft of an AC generator 3 to generate an electromotive force of the AC generator 3. The rectifier 4 connected to the storage battery 1 is electrically connected to the load terminal to which is supplied, and the AC side circuit of the AC motor 5 is electrically connected, the AC motor 5 is driven by the electromotive force, and a part of the electromotive force is rectified. The storage battery 1 is charged via 4 and the drive output of the AC motor 5 is transmitted to the front and rear drive wheels via the gear transmission 6. The propulsion device for an electric vehicle according to the present invention is preferably provided with four AC motors 5 corresponding to front and rear drive wheels and separately driven. In this case, it is more preferable that one AC motor 5 is driven at the time of starting and that one or a plurality of AC motors 5 are driven after starting depending on the road surface condition so as to travel.

本考案の好適な一実施例を図面を用いて説明する。 図１は、本考案の推進装置の一例の構成を概略図で示しており、図中、符号１ は１２Ｖ又は２４Ｖの蓄電容量を有する単位電池を複数個直列に接続し出力端部 間で約１００Ｖの直流電圧が得られるように形成された蓄電池であり、図示され ない充電器を作動させて、車外の給電機から供給される荷電流を充電し得るよう になっている。 A preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the structure of an example of the propulsion device of the present invention. In the figure, reference numeral 1 is a plurality of unit batteries having a storage capacity of 12V or 24V connected in series, and a plurality of unit batteries are connected between output terminals. It is a storage battery formed so as to obtain a DC voltage of 100 V, and can operate a charger (not shown) to charge a load current supplied from a power supply device outside the vehicle.
【０００７】 ２は後述のコントロール盤７を介して蓄電池１から供給される電流により回転 駆動し、その駆動軸を交流発電機３の回転軸に連結して設けた直流電動機、３は 直流電動機２の駆動軸の回転と同期して発電を行なう交流発電機、４は交流発電 機３の負荷端子に電気的に接続する整流器であり、当該整流器で直流に変換され た誘導起電力を上記蓄電池１に充電し得るように設けてある。Reference numeral 2 denotes a DC motor that is rotationally driven by a current supplied from a storage battery 1 via a control panel 7 to be described later, and its drive shaft is connected to a rotation shaft of an AC generator 3, and 3 is a DC motor 2 An AC generator 4 that generates electric power in synchronization with the rotation of the drive shaft of 4 is a rectifier that is electrically connected to the load terminal of the AC generator 3. The induced electromotive force converted into DC by the rectifier is the storage battery 1 described above. It is provided so that it can be charged.
【０００８】 ５は同じく交流発電機３の負荷端子に電気的に接続していて前後の駆動輪を独 立して駆動し得るように各駆動輪毎に設けた交流電動機、６は交流電動機５の駆 動出力を車輪に伝達するギア変速機であり、各車輪一括して又は個別に交流電動 機５との連結ギアを適宜替えて所望の駆動トルクに設定し得るように設けてある 。一台の交流電動機５により全駆動輪を駆動するようにしてもよい。Reference numeral 5 is an AC motor that is also electrically connected to the load terminals of the AC generator 3 and is provided for each drive wheel so that the front and rear drive wheels can be driven independently, and 6 is the AC motor 5 Is a gear transmission that transmits the driving output to the wheels, and is provided so that the driving gear can be set to a desired drive torque by changing the gears connected to the AC motor 5 collectively or individually for each wheel. All the drive wheels may be driven by one AC electric motor 5.
【０００９】 ７はこれら各機器の制御回路を内蔵し、各機器を自動又は手動操作で作動制御 するコントロール盤である。なお、図示されていないが、電気自動車のパワース イッチやハンドル、アクセル、ブレーキ等の運転操作部の各操作信号もコントロ ール盤７に入力され、これら信号に応じて上記各機器が自動的に作動制御される ようにプログラム設定されているものとする。Reference numeral 7 is a control panel which incorporates a control circuit for each of these devices and controls the operation of each device automatically or manually. Although not shown in the figure, the operation signals of the operation switches such as the power switch, steering wheel, accelerator, and brake of the electric vehicle are also input to the control panel 7, and the above devices are automatically operated according to these signals. It shall be programmed to be operationally controlled.
【００１０】 各機器は、例えば１２Ｖの単位電池を９個連結して形成した蓄電池１と、１５ ｋＷの直流電動機２と、１００ｋＷの交流発電機３と、２０ｋＷの整流器４と、 ２５馬力の交流電動機５とを組み合わせて用いることができる。Each device includes, for example, a storage battery 1 formed by connecting nine unit batteries of 12V, a DC motor 2 of 15 kW, an AC generator 3 of 100 kW, a rectifier 4 of 20 kW, and an alternating current of 25 hp. It can be used in combination with the electric motor 5.
【００１１】 本考案の推進装置は上記各部材からなり、電気自動車のパワースイッチを入れ 、コントロール盤７を介して直流電動機２を駆動し、直流電動機２と連結する交 流発電機３の負荷端子間に交流起電力を生じさせ、この誘導起電力で交流電動機 ５を駆動し、ギア変速機６を介して駆動輪を駆動させる。The propulsion device of the present invention comprises the above-mentioned members, turns on the power switch of the electric vehicle, drives the DC motor 2 through the control panel 7, and connects the DC motor 2 to the load terminal of the AC generator 3. An AC electromotive force is generated between them, and the AC electromotive force 5 is driven by this induced electromotive force, and the drive wheels are driven via the gear transmission 6.
【００１２】 この場合、例えば交流発電機３の出力が１００ｋＷであるときは、出力の内の １５ｋＷは整流器４を介して蓄電池１に充電し、残りの８５ｋＷで四台の交流電 動機５を順次駆動させるようにする。すなわち、駆動輪を駆動させながら蓄電池 １に電力を並列的に供給することにより蓄電池１を総合的に保護し、とりわけ停 止する際や坂道を下りる際の制動時に駆動輪の回転エネルギーを吸収して蓄電池 １に充電する回生制動が可能となり、蓄電源の利用効率を高めることができる。In this case, for example, when the output of the AC generator 3 is 100 kW, 15 kW of the output is charged into the storage battery 1 via the rectifier 4, and the remaining 85 kW drives the four AC generators 5 sequentially. I will let you. That is, while driving the drive wheels, the storage battery 1 is comprehensively protected by supplying electric power to the storage battery 1 in parallel, and the rotational energy of the drive wheels is absorbed especially during braking when stopping or going down a slope. As a result, regenerative braking that charges the storage battery 1 becomes possible, and the utilization efficiency of the storage power source can be improved.
【００１３】 また、交流電動機５を四台設けておけば、起動時に８５ｋＷの電力で一台の交 流電動機５を駆動することにより励磁電流を大きくして起動に必要な十分な大き さのトルクを得、その後、走行中に他の交流電動機５を順次駆動することにより 過電流の発生を抑止しつつ、スムーズに始動し走行させることが可能となる。更 に、四台の交流電動機５を独立に駆動可能に設けることにより、平地運転時は二 台、坂道運転時には四台の交流電動機５でそれぞれ運転し、路面状況に応じた快 適な走行性を得ることが可能となる。If four AC motors 5 are provided, the exciting current is increased by driving one AC motor 5 with a power of 85 kW at the time of start-up to increase the torque of a sufficient amount necessary for start-up. After that, by sequentially driving the other AC motors 5 during traveling, it is possible to smoothly start and run while suppressing the occurrence of overcurrent. In addition, by providing four AC motors 5 that can be driven independently, two AC motors 5 can be operated during flatland operation and four AC motors 5 during slope operation, respectively, to provide optimum driving performance according to road conditions. Can be obtained.
【００１４】 本考案の推進装置は、駆動輪を交流電動機により駆動しているから、直流電動 機により駆動する場合のように始動時の過電流の発生がなく、同容量の蓄電池を 長時間使用することが可能となる。In the propulsion device of the present invention, since the drive wheels are driven by an AC motor, overcurrent at the time of starting does not occur unlike when driven by a DC motor, and a storage battery of the same capacity is used for a long time. It becomes possible to do.
