Abstract:
1. A multi-ratio transmission system with parallel vertical and coaxial planet gears, comprising: a plurality of planet gear sub-systems, being coaxially disposed in series along a first axis, each of said planet gear sub-system comprising: a coupling assembly disposed between every two adjacent said planet gear sub-systems so as to transmit rotation of said planet gear of the former said planet gear sub-system to said planet gear of the latter said planet gear sub-system; a setting element disposed corresponding to each of said planet gear sub-systems, wherein said setting element optionally moves in the direction of said first axis so as to optionally engage with said sun gear of said planet gear sub-system; a setting element controller connected to said setting element of each of said planet gear sub-systems to optionally move said setting element of a respective one of said planet gear sub-systems, thereby enabling said setting element to optionally engage with said sun gear of said respective one of said planet gear sub-systems; and an annular gear engaged to said planet gear of at least one planet gear sub-system.
