Multi-speed transmission with countershaft gearing
摘要:
A transmission is provided having a dual clutch and a countershaft gearing arrangement. The countershaft gearing arrangement includes a plurality of co-planar gears sets having gears that are selectively connectable to at least two countershafts. Moreover, one of the gears of the plurality of co-planar gears sets that provides a reverse gear ratio is selectively connectable to a first countershaft and is in mesh with only one other gear of the plurality of co-planar gears sets that is selectively engagable to a second countershaft.
