7-SPEED LAYSHAFT GEARTRAIN WITH DUAL-USE MESHES AND THREE AXES
摘要:
A dual mesh gear system is provided for a motor vehicle transmission having three axes. The transmission includes two input shafts, first and second clutch assemblies, first and second countershafts, and an output shaft. The transmission uses a first dual mesh for gears four and six and a second dual mesh for gears five and seven. Reverse within the transmission is driven by a reverse driver gear fixedly attached to second gear on the second countershaft. The reverse driver gear is continuously meshed with a reverse driven gear on the first countershaft. The reverse gear combination achieves a reverse gear ratio greater than or equal to the gear ratio of first gear.
