TechnicBrickPower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHi Everyone, I have created this 4 speed gearbox based on the "change over rotary catch" component and I have used it to select 1 of 4 gearing inputs in possibly a new way by connecting to four clutch gears which then connect to a differential housing used as a method to transfer motion whilst allowing the rotary catch to be rotated freely inside of it. The gearbox implements 3 forward speeds, and 1 reverse. I was wondering if anyone has seen this technique before (I am guessing yes since most ideas are not new)? Anyway thanks in advance.
