Posted June 23, 20204 yr Here I present my 12 speed gearbox design. The gearbox implements 3 reverse speeds, a stop gear (zero speed), and 8 forward speeds. The forward speeds range from 0.307 to 1.2 and reverse from -0.067 to -0.36. The gearbox has a single gear lever to drive two rotary selectors to select the gears. Let me know if you like it, have any comments or questions.

June 23, 20204 yr Hi. As in your 4 speed gearbox, you use only one side of the driving rings. This seems interesting to me as it might reduce friction problems (maybe at the cost of a bigger size). Am I right?

I have my own url now too which is easier to remember.. http://www.youtube.com/technicbrickpower On 6/24/2020 at 9:26 AM, vascolp said: Hi.

I am not sure to be honest - I have never measured the friction of a gearbox but that will be worthwhile doing. I don't think the friction will be a lot less as the central axes of the driving ring is still rotating and held in place by a liftarm hole.
