Amplified transmission mechanism for e.g. scooter, has amplifier system including gearset whose gears and carrier are arranged such that mechanical transmission is installed between one of gears and transmission shaft

摘要

The mechanism has a mechanical amplifier system including a planetary gearset (4) provided with two side gears (41, 43) and a planet carrier that are arranged such that an input shaft (1) transmits a movement to the carrier and another movement to one of transmission shafts. The side gears and the carrier are arranged such that an output shaft (2) is connected to one of side gears and a mechanical multi-speed ratio transmission (3) e.g. gear box, is installed between the other side gear and another transmission shaft.
