Title
(EN) DUAL-CLUTCH TRANSMISSION
(FR) TRANSMISSION À DOUBLE EMBRAYAGE
(JA) デュアルクラッチ式変速機
Abstract
(EN) This dual-clutch transmission is provided with a dual-clutch device 20, a first primary gear train 41 for transmitting power from a first input shaft 31 to a countershaft 34, a second primary gear train 42 for transmitting power from a second input shaft 32 to the countershaft 34, a plurality of output gear trains 51-53 rotatably provided to an output shaft 33, and a synchronizing mechanism 60 for shifting the output gear trains 51-53. The step ratio for gearshifting during which only the clutch is changed is set to be less than the step ratio for gearshifting during which both the clutch and the gears are changed.
(FR) La transmission à double embrayage selon l'invention est dotée d'un dispositif à double embrayage 20, d'un premier train d'engrenages primaire 41 pour transmettre la puissance d'un premier arbre d'entrée 31 à un arbre intermédiaire 34, d'un second train d'engrenages primaire 42 pour transmettre la puissance d'un second arbre d'entrée 32 à l'arbre intermédiaire 34, d'une pluralité de trains d'engrenages de sortie 51 à 53 montés de manière rotative sur un arbre de sortie 33, et d'un mécanisme de synchronisation 60 pour décaler les trains d'engrenages de sortie 51 à 53. Le rapport de changement de vitesse pendant lequel seul l'embrayage est changé est défini à une valeur inférieure à celle du rapport de changement de vitesse pendant lequel à la fois l'embrayage et les vitesses sont changés.
(JA) デュアルクラッチ装置20と、第1入力軸31から副軸34に動力を伝達する第1プライマリギヤ列41と、第2入力軸32から副軸34に動力を伝達する第2プライマリギヤ列42と、出力軸33に回転可能に設けられた複数の出力用ギヤ列51~53と、出力用ギヤ列51~53をギヤインさせるシンクロ機構60とを備え、クラッチ切り替えのみで行う変速間のステップ比が、クラッチ切り替え及びギヤ切り替えの両方を行う変速間のステップ比よりも小さいステップ比で設定された。
