VEHICLE TRANSMISSION

摘要

A vehicle transmission has at least three transmission gears. The at least three transmission gears are selectively engaged by at least three shifting sleeves. The shifting sleeves are actuated by two shift forks. Each shift fork is moved by a corresponding shift drum. The shift drums are disposed on a shift drum shaft. By rotating the shift drum shaft, each of the at least three transmission gears can be engaged in sequence. The two shift drums are spring biased.
