Abstract

See full text

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.
