Twin clutch transmission

摘要

A twin clutch transmission for a large horsepower vehicle having a compact size and a high transmission efficiency is obtained. In a twin clutch transmission, there are provided an input shaft, an odd-numbered level speed change mechanism 30, an even-numbered level speed change mechanism 60, a synchronizing speed change mechanism 100, and an output mechanism 90. The speed change mechanisms 30 and 60 include transmission gear trains 32 and 62, main clutches 34 and 64 for selectively transmitting the powers of the transmission gear trains 32 and 62 to the transmission shafts 40 and 70. The synchronizing speed change mechanism 100 includes synchronizing gear trains 110 and 120 for coupling the rotation of the odd-numbered level transmission shaft 32 with the rotation of the even-numbered level transmission shaft 62, and synchronizing clutches 112 and 122 for selecting coupling by this synchronizing gear train.

1. A twin clutch transmission comprising:
an input shaft to which a power of an engine is inputted; an output shaft from which at least a rotation in a first direction is outputted; an odd-numbered level speed change mechanism to which a rotation of the input shaft is transmitted, the odd-numbered level speed change mechanism performing a speed change of an odd-numbered level when the output shaft is rotated in the first direction; an even-numbered level speed change mechanism to which a rotation of the input shaft is transmitted, the even-numbered level speed change mechanism performing a speed change of an even-numbered level when the output shaft is rotated in the first direction; a synchronizing speed change mechanism for synchronizing the odd-numbered level speed change mechanism and the even-numbered level speed change mechanism at a time of a speed change; and an output mechanism for transmitting powers of the odd-numbered level speed change mechanism and the even-numbered level speed change mechanism to the output shaft, wherein: the odd-numbered level speed change mechanism includes an odd-numbered level transmission shaft, an odd-numbered level transmission gear train placed between the input shaft and the odd-numbered level transmission shaft, an odd-numbered level main clutch for selectively transmitting a rotation of the input shaft to the odd-numbered level transmission shaft via the odd-numbered level transmission gear train, an odd-numbered level speed-changing gear train provided on the odd-numbered level transmission shaft, the odd-numbered level speed-changing gear train transmitting the rotation to the output mechanism, and an odd-numbered level mechanical clutch for selectively coupling the odd-numbered level speed-changing gear train with the odd-numbered level transmission shaft; the even-numbered level speed change mechanism includes an even-numbered level transmission shaft, an even-numbered level transmission gear train placed between the input shaft and the even-numbered level transmission shaft, an even-numbered level main clutch for selectively transmitting a rotation of the input shaft to the even-numbered level transmission shaft via the even-numbered level transmission gear train, an even-numbered level speed-changing gear train provided on the even-numbered level transmission shaft, the even-numbered level speed-changing gear train transmitting the rotation to the output mechanism, and an even-numbered level mechanical clutch for selectively coupling the even-numbered level speed-changing gear train with the even-numbered level transmission shaft; and the synchronizing speed change mechanism includes a synchronizing gear train for coupling a rotation of the odd-numbered level transmission shaft with that of the even-numbered level transmission shaft, and a synchronizing clutch for selecting coupling by the synchronizing gear train.
