VEHICLE DRIVING FORCE TRANSMISSION STRUCTURE

摘要

The vehicle driving force transmission structure of a power unit can include a main transmission having a transmission shaft group and parallel to a crankshaft and provided in a crankcase on the side of the crankshaft. The transmission structure can also include a large rotational body provided at an end of the crankshaft, and an auxiliary transmission provided as a separate body from and connecting to the main transmission. The auxiliary transmission has a transmission shaft group parallel to the transmission shaft group of the main transmission and disposed so as to form a periphery of the large rotational body. The auxiliary transmission includes a transmission driving mechanism disposed below the large rotational body.
