摘要： A powertrain for a snowmobile includes an engine, a gearbox input shaft receiving rotational energy from the engine and a reversible belt drive assembly coupled to the gearbox input shaft. The reversible belt drive assembly is switchable between a forward mode and a reverse mode and includes a pulley, a planetary gear system coaxial with the pulley and a selector collar assembly interposed between the pulley and the planetary gear system translatable between a first position to form a forward geartrain bypassing the planetary gear system in the forward mode and a second position to form a reverse geartrain including the planetary gear system in the reverse mode.
