MULTISTAGE TRANSMISSION DEVICE

摘要

A multistage transmission device includes a plurality of driving gears provided in a countershaft, a plurality of driven gears meshing with the driving gears, respectively, dog rings that switch mechanical connection or disconnection between the drive shaft and each of the driven gears, and one-way clutches arranged between the countershaft and the driving gears. The one-way clutches transmit rotation of the countershaft to the driving gears when the rotation of the countershaft is faster than the rotation of the driving gears.

1. A multistage transmission device comprising:
a countershaft that receives a drive force; a drive shaft that outputs the drive force received from the countershaft; a plurality of driving gears provided in the countershaft; a plurality of driven gears respectively meshing with the plurality of driving gears; a drive shaft-side transmission member that switches mechanical connection or disconnection between the drive shaft and the driven gears; and a one-way clutch arranged between the countershaft and at least predetermined one of the driving gears to transmit rotation of the countershaft to the predetermined driving gear when the rotation of the countershaft is faster than rotation of the predetermined driving gear.
