Continuously variable transmission with levers and idlers has driven lever joined to connecting rod by mechanism movable along rod axis to vary driven lever motion range and hence transmission ratio

摘要

The device has at least one crank drive (1,4,22) with at least one drive wheel (4), at least one connecting rod (1) joined at one end to the drive wheel at an eccentric point (12) and at the other to a first rod of a linear guide (22) and at least one driven lever (2) joined to the connecting rod at one end by a mechanism (5) movable along the connecting rod axis to vary the driven lever's range of movement and hence the transmission ratio.
