piterx Posted June 16, 2013 Posted June 16, 2013 (edited) hi guys! im away from my legos for some days but i have something i didn't show you :) this is my idea for a high and low ratio gearbox for a 4x4 that im doing.... i think it's nice because it's only 3 studs wide and it's 5 studs from the input to the output it also hosts a free axle for an eventual second function such as a steering system hope you like it and it's gonna be useful Edited June 16, 2013 by piterx Quote
Doc_Brown Posted June 16, 2013 Posted June 16, 2013 (edited) "im away from my legos for some days" This is just not good enuf!~! :P I guess I will have to build it to see! :D Great job on its compactness Edit: After following the path of motion using my "imagination" :P I have a feeling that the torque will separate the 8t from the 24t for the low gear. Have you tested this? Could be wrong tho. :D Edited June 16, 2013 by Doc_Brown Quote
piterx Posted June 16, 2013 Author Posted June 16, 2013 yea it could be but it has to be braced someway to the chassis so it doesn't dismount :P Quote
Doc_Brown Posted June 16, 2013 Posted June 16, 2013 sweet, any idea on a mechanism to hold the ring in place? :D Quote
piterx Posted June 16, 2013 Author Posted June 16, 2013 hmmm not yet and i can't even test anything for now... anyway i will connect the gear selector to the rear differential so when the low ratio is selected the differential gets locked for a better climbing Quote
Lipko Posted June 16, 2013 Posted June 16, 2013 If you used a driving ring extension piece, you could save some gears, the second layer of axles and gears would be gone, and it would be only one stud longer. Your solution is too complex for such a simple thing. Quote

piterx Posted June 16, 2013 Author Posted June 16, 2013 hmmm yeah i guess the one you posted is better :P nice to know lol Quote
Lipko Posted June 16, 2013 Posted June 16, 2013 Was the gearbox (transpher case 1) in this pic what you was thinking of? Exactly. I am making instructions like crazy so I didn't bother looking it up. Quote
nikolyakov Posted June 16, 2013 Posted June 16, 2013 i think it's nice because it's only 3 studs wide and it's 5 studs from the input to the output How it can be 3 stud wide with old 4 stud differantial? Quote
piterx Posted June 16, 2013 Author Posted June 16, 2013 because im talking about width and not lenght :P Quote
