Abstract:
PROBLEM TO BE SOLVED: To effectively reduce an incongruity of a driver by suppressing a variation of a necessary time of each gear change.SOLUTION: A dual clutch type transmission comprises: a dual clutch device 20; a first primary gear row 41 for transmitting power to a countershaft 34 from a first input shaft 31; a second primary gear row 42 for transmitting power to the countershaft 34 from a second input shaft 32; a plurality of output gear rows 51 to 53 which are rotatably arranged at an output shaft 33; and a synchronization mechanism 60 which makes the output gear rows 51 to 53 gear in. A step ratio between gear changes which are performed by only clutch switching is set at a step ratio which is smaller than a step ratio between gear changes which are performed by both the clutch switching and gear switching.SELECTED DRAWING: Figure 1
