piterx Posted June 16, 2012 Posted June 16, 2012 i dont know if somone created it before me but anyway... here's the solution i've found trying to assembly a 1N2 gearbox the smallest i could i've used this in the wrangler and in the 8c it has a gear ratio 1:1 and another one of your choice Quote
timslegos Posted June 16, 2012 Posted June 16, 2012 Would you mind posting a picture with one of the black sides off? Otherwise very nice design. Tim Quote

Tim there's no need dude! there are no hidden parts except for the parts u need to attach it on a chassis :) try to build it its really simple :P Quote
skppo Posted June 16, 2012 Posted June 16, 2012 By using the 4-wide diff you can actually make a similar gearbox using only two axles (input and output). It is longer and the diff makes it look kinda dumb but it narrower and symmetrical. Man, i wish lego would make those dark gray gears in diffrent sizes, would make gearboxes less of an hassle and more realistic too. Quote

88high Posted June 16, 2012 Posted June 16, 2012 (edited) Mmm... I am not sure of your dimensions, but I know I have made a gearbox in a 5X7 by 3 deep. It was a 3-speed linear. Edited June 16, 2012 by 88high Quote

piterx Posted June 17, 2012 Author Posted June 17, 2012 cool! yeah on the one i posted you're not limited on gears ratio.. you have a 1:1 and another one that you can set the way you want :P its good both for "speed" cars and offroad cars Quote

KEvron Yup this is what i've been saying. Idler gears with 24, 22, 20 and 18 teeth to go with the 16t one we already have, as well as spur gears with 10 and 14 teeth to go with the 8, 12 and 20 tooth gears we already have would make a much better gearbox, even better if 2 idlers and 1 driving ring in a line was only 3 studs long instead of 4. This would make the gearbox more compact and allow more intuative placement of the gear change parts (no need for half stud offset). Quote

So, you want to have gears: 8t, 12t, 14t, 16t, 18t, 20t, 22t, 24t, 26t, 28t, 30t, 32t, 34t, 36t, 38t, 40t, 42t, 44t, 46t, 48t, 50t, 52t, 54t, 56t, 58t, 60t ? All clutch. Quote

All clutch. Nope, just the ones I said. A total of 5 ranging from 16 to 24 teeth, or maybe even a 6th one with 12 or 14 teeth. Quote
nielsvdv Posted June 20, 2012 Posted June 20, 2012 nice setup :) i have built something like that before, only the ratios are different. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=448047 regards, nielsvdv Quote
Alasdair Ryan Posted June 20, 2012 Posted June 20, 2012 If it is size that you like you could use a Lego technic triangle lift-arm on either side,this would make it one stud less. Quote
