| Abstract(J) | 二つの既存モータと遊星歯車および動力切替え機構を組み合わせ，全走行シーンに対応する大出力電動駆動システムを提案する．二つのモータ出力に対し，遊星歯車を高負荷・低速時には減速機として使用して各モータの損失を低減することで，システムの連続運転が可能な領域を約36%拡大できることをベンチ試験で確認した． Translation |
| Abstract(E) | This paper proposes a new drive system for a large EV that achieves low cost, high power, and low power consumption by combining conventional motors and a simple gearbox. This system runs using one motor in the low-speed range and two motors in the high-speed range, and can switch between the two modes smoothly. Furthermore, in the two-motor mode, planetary gears are used as a differential device when driving under light loads in the high-speed range, and as a reduction device when driving under heavy loads in the low-speed range. This reduces the loss of each motor and expands the continuous operation range of the system. Bench tests showed that switching modes can increase the continuous operating range of the motor system by 36.2%, while enhancing its heat-resistance reliability. |
