Stepless speed change gear for motor propulsion systems of motor vehicles

摘要

A stepless speed change gear of the type in which a main shaft and a driven shaft have respective pulleys formed by plates of controlled variable separation, interconnected by a vee belt. A drive shaft is housed coaxially within the main shaft and connected at one end through a friction clutch with a driving shaft of an engine, the other end of the drive shaft being connected to the main shaft through a reversing gear including an epicyclic gear train.
