本発明に係るデュアルモーターによる駆動システムは、稼働の際に、図２を参照すると、電気トラクターを、緩い坂道／上がり坂＋ＰＴＯモード、牽引、低速の四輪駆動及び高速の二輪駆動モードという四つの稼働モードで稼働させることができる。 In the dual motor drive system according to the present invention, when operating, referring to FIG. 2, the electric tractor has four modes: gentle slope / uphill + PTO mode, traction, low-speed four-wheel drive, and high-speed two-wheel drive mode. It can be operated in the operation mode.

緩い坂道／上がり坂＋ＰＴＯモードにある場合には、第一駆動モーター６により、車が走行するように駆動し、それと同時に、第二駆動モーター１１により、動力出力軸伝動ケース２を駆動し、第一駆動モーター６及び第二駆動モーター１１は、共に、高いパワーモードに設定される。当該モードは、主に、電気トラクターによるロータリ耕うん、溝開け、収穫や移植等の作業に用いられるものである。前車軸と作業具との両者により駆動を行うことにより、車全体を駆動するというニーズを満たすことができるだけではなく、ＰＴＯによる出力パワーが、トラクターを設計するという基準の要求を満たすようにすることもできる。稼働時には、二つのギアを有する前変速機１０が低速ギアにあり、第一駆動モーター６は、前車軸変速機１０及び前伝動軸が回転するように駆動して、その動力を車軸に伝達し、前車輪が回転するように連動することにより、車全体が走行するように駆動する。第二駆動モーター１１は、後車軸変速機５が回転するように駆動し、ＰＴＯクラッチ１２を接続して、駆動ＰＴＯ伝動軸及び動力出力軸伝動ケース２が回転するようにすることにより、ロータリ耕うんの機器が稼働するように駆動すると、後車軸が駆動しないように、接続後車軸クラッチ４を切断する。 When in a gentle slope / uphill + PTO mode, the first drive motor 6 drives the vehicle to run, and at the same time, the second drive motor 11 drives the power output shaft transmission case 2. Both the one drive motor 6 and the second drive motor 11 are set to a high power mode. This mode is mainly used for operations such as rotary tillage, grooving, harvesting and transplanting with an electric tractor. By driving with both the front axle and the work equipment, not only can the need to drive the entire vehicle be met, but the output power of the PTO also meets the requirements of the criteria for designing a tractor. You can also. At the time of operation, the front transmission 10 having two gears is in the low speed gear, and the first drive motor 6 drives the front axle transmission 10 and the front transmission shaft so as to rotate, and transmits the power to the axle. By interlocking the front wheels so that they rotate, the entire vehicle is driven to run. The second drive motor 11 is driven so that the rear axle transmission 5 rotates, and the PTO clutch 12 is connected so that the drive PTO transmission shaft and the power output shaft transmission case 2 rotate, thereby tilling the rotary. When the device is driven to operate, the rear axle clutch 4 is disengaged so that the rear axle is not driven.

牽引モードにある場合には、第一駆動モーター６及び第二駆動モーター１１により、車全体が走行するように駆動し、ＰＴＯクラッチ１２が切断し、ＰＴＯが動力を出力しない。二つのギアを有する前変速機１０は、高速ギアにあり、二つのギアを有する後変速機５は、低速ギアにある。第一駆動モーター６及び第二駆動モーター１１は、共に、高いパワーモードに設定されており、当該モード主は、主に、電気トラクターによる耕うん、ならしや中耕などの作業に用いられるものである。 In the traction mode, the first drive motor 6 and the second drive motor 11 drive the entire vehicle to run, the PTO clutch 12 is disengaged, and the PTO does not output power. The front transmission 10 with two gears is in the high speed gear and the rear transmission 5 with the two gears is in the low speed gear. Both the first drive motor 6 and the second drive motor 11 are set to a high power mode, and the mode main is mainly used for work such as tilling by an electric tractor, break-in, and middle tillage. ..

低速の四輪駆動のモードにある場合には、第一駆動モーター６及び第二駆動モーター１１により、車全体が走行するように駆動し、ＰＴＯクラッチ１２が切断し、ＰＴＯが動力を出力しない。二つのギアを有する前変速機１０は、高速ギアにあり、二つのギアを有する後変速機５は、低速ギアにある。第一駆動モーター６及び第二駆動モーター１１は、共に、低いパワーモードに設定されており、当該モードは、主に、電気トラクターによる圃場播種、施肥、薬剤散布、圃場移送や機具連結などの作業に用いられるものである。稼働の過程は、牽引モードのほうと同じである。 In the low-speed four-wheel drive mode, the first drive motor 6 and the second drive motor 11 drive the entire vehicle to run, the PTO clutch 12 is disengaged, and the PTO does not output power. The front transmission 10 with two gears is in the high speed gear and the rear transmission 5 with the two gears is in the low speed gear. Both the first drive motor 6 and the second drive motor 11 are set to a low power mode, in which the mode is mainly for work such as field sowing, fertilization, chemical spraying, field transfer and equipment connection by an electric tractor. It is used for. The process of operation is the same as in the traction mode.

高速の二輪駆動のモードにある場合には、第一駆動モーター６が稼働せず、第二駆動モーター１１により、後車軸車輪が回転して、車全体が走行するように駆動することにより、車全体を道路で輸送し又は移送する作業というニーズを満たすことができる。後変速機５は、高速ギアにある。稼働の過程については、第一駆動モーター６が稼働せず、前車軸変速機１０がニュートラルギアにあり、第二駆動モーター１１により変速機が回転するように駆動し、接続後車軸クラッチを接続して、動力を伝動軸から後車軸に伝達し、後車輪１が回転するように駆動し、ＰＴＯクラッチ１２が切断し、ＰＴＯが動力を出力しない。車全体は、後車輪による駆動を介して、高速で走行する。 In the high-speed two-wheel drive mode, the first drive motor 6 does not operate, and the second drive motor 11 rotates the rear axle wheels to drive the entire vehicle to run. It can meet the needs of transporting or transporting the whole by road. The rear derailleur 5 is in high speed gear. Regarding the process of operation, the first drive motor 6 does not operate, the front axle transmission 10 is in the neutral gear, the second drive motor 11 drives the transmission to rotate, and the rear axle clutch is connected. Then, the power is transmitted from the transmission shaft to the rear axle, the rear wheel 1 is driven to rotate, the PTO clutch 12 is disengaged, and the PTO does not output the power. The entire vehicle travels at high speeds, driven by the rear wheels.

本発明は、二つの動力源を採用しており、つまり、第一駆動モーター６及び第二駆動モーター１１という二つのモーターは、それぞれ、後変速機５及び前車軸変速機１０を駆動することにより、前車輪９、後車輪１及びＰＴＯを駆動するという機能を実現する。 The present invention employs two power sources, that is, the two motors, the first drive motor 6 and the second drive motor 11, drive the rear transmission 5 and the front axle transmission 10, respectively. , The function of driving the front wheel 9, the rear wheel 1 and the PTO is realized.

本発明は、後制御手段１３及び前制御手段７により、第二駆動モーター１１及び第一駆動モーター６をそれぞれ制御し、第二駆動モーター１１及び第一駆動モーター６は、そのパワーが、電気制御システムを介して、それぞれ、高いパワーモードと低いパワーモードに設置される。つまり、モーターの外部特性が設置されている。それと同時に、多種類のパワーモードを組み合わせることにより、多種類のパワーを出力することができる。本発明は、二つのモーター、二つのギアを有する二つの変速機のギア、ＰＴＯクラッチ１２及び接続後車軸クラッチ４の制御が、電気制御又は電気油圧制御により実現され、トラクターを知能化制御する発展のニーズを満たすことが可能である。 In the present invention, the second drive motor 11 and the first drive motor 6 are controlled by the rear control means 13 and the front control means 7, respectively, and the power of the second drive motor 11 and the first drive motor 6 is electrically controlled. Through the system, they are installed in high power mode and low power mode, respectively. That is, the external characteristics of the motor are installed. At the same time, by combining various types of power modes, it is possible to output various types of power. According to the present invention, the control of two motors, two transmission gears having two gears, a PTO clutch 12 and a rear axle clutch 4 is realized by electric control or electrohydraulic control, and the tractor is intelligently controlled.

By combining the modes, it is possible to output various types of transmission patterns.

本発明は、多種類のパワー出力モードの組み合わせにより、トラクターが作業する普通の状況において、緩い坂道／上がり坂＋ＰＴＯモード、牽引、低速の四輪駆動及び高速の二輪駆動モードという四つの稼働モードを実現できる。本発明は、一般的な内燃機関型のトラクターに比べると、モーターが効率の高い領域に有する幅広い特性、及び、二つのギアを有する二つの変速機のギアを組み合わせるにより、トラクターに各種類の稼働モードを実現することにより、従来における複雑な変速機を、二つのギアを有する二つの変速機に簡素化させ、伝動の過程を減らし、トラクターの変速機の構成を簡単化させ、コストを削減させ、伝動の効率を高めることができる。 The present invention combines four power output modes to provide four operating modes: gentle slope / uphill + PTO mode, traction, low speed four-wheel drive and high speed two-wheel drive in normal tractor working situations. realizable. Compared to a general internal combustion engine type tractor, the present invention combines a wide range of characteristics that a motor has in a high efficiency area and the gears of two transmissions having two gears, so that each type of operation can be performed on the tractor. By realizing the mode, the conventional complicated transmission is simplified to two transmissions with two gears, the transmission process is reduced, the tractor transmission transmission configuration is simplified, and the cost is reduced. , The efficiency of transmission can be increased.
