Abstract
A dual clutch transmission (DCT) with double-range change. In one embodiment, the dual clutch transmission includes odd and even lay shafts and a separate range change shaft for each, thereby providing a range change for both the odd and even gear sets. The input shaft may include an extension gear that can be selectively driven by the inner input shaft or the outer input shaft to provide additional gear pairings. The extension gear may include a synchronizer on each face to allow it to be coupled to either the outer or inner input shaft. The transmission may include a reverse shaft coupled with the even lay shaft. The transmission may include a dual half synchronizer having a single hub and a split sleeve. The parts of the split sleeve are separately movable to allow independent synchronization of two pairs of rotating components.
