Watch: Check out this 5-speed manual transmission in Lego – News
Youtuber and Lego build master Brick Technology posted a video showing the creation of a fully functional five-speed manual transmission with reverse.
It’s not just a Lego masterpiece, but shows off the intricate workings of a manual transmission and even highlights the importance of gear ratios.
The build starts with a more simplistic 2-speed gearbox, driven by an electric motor.
The transmission is then developed even further, as two more sets of gears are added.
In the end, there are a total of 5 gears that follow a normal manual transmission setup. After most of the drivetrain was completed, Brick Technology fabricated a shifter.
Building the shifter took some trial and error. Reinforcement parts were added which ultimately led to a very precise and tight transmission.
That’s when the shifter was added to the 5-speed transmission before Brick Technology tried it. Once in place, there were a few flaws to iron out before it was perfected.
After that, Brick Technology worked on adding upside down.
Finally, it was hooked up to a Lego dyno. The complete Lego build was run on the dyno shifting between all five gears and full speed reverse.
