Transmission

摘要

A transmission has a rotating shaft (2), a coupling sleeve (C3) fixedly coupled to the rotating shaft to rotate with the rotating shaft and a variable speed gear (G6) mounted on the rotating shaft. The variable speed gear is configured to rotate on the rotating shaft when a clutch gear (CG) that is embedded in a side surface of the variable speed gear is disengaged from the coupling sleeve and to be fixed to the rotating shaft when the clutch gear is engaged from the coupling sleeve. The coupling sleeve is moved in the axial direction between the engaged and disengaged states by a shifting fork (F3,F30). A lubricant supplying structure directs lubricant to the clutch gear by diverting the lubricant against a side surface of the shifting fork that faces the clutch gear and a side surface of the coupling sleeve that faces the clutch gear.
