TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A toroidal continuously variable transmission for use in front engine front drive vehicles to which a geared neutral starting system is adopted. An input shaft (11) one of whose ends is connected to an engine (1), a primary shaft (12) which is movably fitted on the shaft and a secondary shaft (13) which is in parallel to these and to whose end on the engine side is connected a differential device (5). Toroidal continuously variable transmission mechanisms (20, 30) are arranged on the primary shaft (12), and a planetary gear mechanism (50), on the secondary shaft (13). A low mode gear train (80) connecting the input shaft (11) and a carrier (51) of the planetary gear mechanism (50) and a high mode gear train (90) connecting a sun gear (52) and an output disk (34) of the transmission mechanisms (20, 30) are provided. The low mode gear train (80) is disposed at the end, opposed to the engine, of the input shaft (11) and other components.
