Automatic Lego Transmission using a Fly-Wheel (Ugly Prototype 3)

[evilguigui21]

that's a freaking CVT!!!!!

[brandonhughes7]

oh i see how it works very nice work man ill sub because this is awesome. its a lot better then my manual 10 speed transmission i made out of legos

[browserhead]

Nice One.

I've been watching your instructinal videos and have used a system based on your models to build my own transmission and gearbox. However, I'm using it to build up speed and reduce torque on a Lego Flying Device.

Keep up the great work!

[ejzllanes96]

is that the same principle that a real car A/T work? also is that the same principle of the manual overide in an A/T?

[knightrider1545]

it is possible to make a lego automatic transmission fluid-wise

[yosip1115]

Very cool

[labattblue1981]

Ron Paul 2012, It's about time we elect a president who doesn't compromise on liberty and freedom!

[javelinthrower1]

dude i really want to know like exactly how you built this...its soo awesome

[destroyer11469]

with all the stuff ive seen in my life this is just incredible

[frasse102]

i agree ugly! but damn good thinkin', thumbs up :D

[Snoep76239]

Awesome! To get it to shift @ lower flywheel speed, you just need more weight on the arms (of centrifugal expander). Stick-on lead wheel-weights should do the trick, and can be shaved with a knife to balance them.

[bcouri1]

This is really fucking cool. No joke. Props.

[MaxWoobs]

Thumbs Up For Treadmill :D

[origamix72]

It's on a treadmill. But good job

[nathanamorley]

Very nice job. I would like to recreate this and have some questions for you. Did you have to destroy a differential to get the dark grey sliding gear? Wouldn't putting a powered shifting mechanism and clutch in place solve your grinding problem? also have you tried putting this in a vehicle with an on board power supply?

[NathansBackwoods]

awesome.

[PyreManiacz]

That is absolutely fucking amazing.

[mrdevilfox69]

dude your brilliant i really like how you have build an automatic transmission, do you atleast have a picture of top and bottom and side by side so i can see how it really works

[killkev91]

this is my new hobbie i need to know everything about this were to get parts things everything i need ppllllleeeeeeaaaaassseeeeee

[fatqwert200]

i fucken like that set up

[tklein930]

may i know the mechanics behind this contraption?

[AviatorBJP]

@tklein930 I made an eight part instructional video, but it may not answer your question. The physics of this device is purely mechanical energy. Rotational energy results in a centripetal force, which acts against a rubber band inside an rpm governor. If the RPM increases to a certain point, the centripetal force overcomes the inward force of the rubber band and causes the gears to shift in order to maintain equilibrium.

[Unite2Kill]

needs a clutch because i sound like it was breaking

[dtiydr]

Cool!

[Fr3dFr3dburg3r1993]

OMG :O that is Awesome! can you sell this to me I would be willing to buy it thing is I don't have all those parts to build an automatic so could you please sell it if you do I would be willing to perfect the design :D

[TheUuuutuber]

thts cool

[PhantomStrain]

Awesome! By the way, what's the sliding gray gear? It looks like the one side of a Lego differential.

[ITSxBLEH]

Were can i buy lego gear set?? all i want is to have the gears and the rods with connectors. Please help i dont know were to look!

[WrongTimeline]

@ITSxBLEH You can look up part names on peeron(dot)com and buy just about any parts individually on eBay.

[tucense]

G-G-G-GRINDDD.. :'(

[MadddcHarlie]

that is the best use for a tread mill ever !

[Rosher18]

This is really fantastic! I love how it even gear-hunts when the wheel speed changes rapidly. It acts just like an actual automatic.

[DJSI3434]

what did you but it on?



[terminater58]

Nice vid

[Dogman36]

i think you should hook up an LPE 4 cylinder to really test this puppy!

[DanielleHallett]

Wonderful!

It might not look "pretty", but it's one of the most beautiful things I've seen in Lego; how did you get the plastic components to handle the flywheel load at high RPM? I would have expected the plasic to warp and/or fail.

[AviatorBJP]

@DanielleHallett. Actually, several peices have failed over time. The biggest issue I have had is with melted shafts. This is one of the reasons I abandoned this particular design for the transmission. I want to acheive the same thing with a slower fly-wheel speed.

[booneman625]

am i the only one who noticed its om a treadmil?

[AviatorBJP]

@booneman625 No, many others know it. I thought it was obvious, otherwise I would have mentioned it.

[morris850]

@AviatorBJP That's why no one mentioned it.

[rockerseven]

@booneman625 at first when i saw this video i thought it was a long hallway, till it seemed to be a never ending hallway

then after seeing his hand, i thought maybe he was actually in a car moving it along (while someone else drove the car)

but then i finally figured out it was a treadmill lol

it should also be noted that when i first saw this video, the quality wasnt that high, so it wasnt easy to make out the treadmill

[TheMasonpants]

@booneman625 the tredmil is pulling it

[Darkehfromwk]

@booneman625 I noticed.

[SuperNewsJunky]

Damn, that's a long hallway!

[caz1135]

this is the best ato lego transmission ever!!!!!!!!!!! I'm trying to build one like it right now. it is very dificult. i like this one better than your new one:P

[MrJimmilicious]

wow thats awesome

[alexmiller532]

i really like this. brilliant

[lowkey213]

like whow lol, send me some instructions

[orbassasin]

I think of all the autobox lego transmissions, I like this one the most as it is probably the closest in theory to a real cars autobox. They don't shift based on load, they shift based on the governor rpms and telling them when to shift. If you put a car in the air and leave it in drive it will automatically shift through the gears to high gear. The engine wants to idle and depending on the gear ratios, it will shift up until the drivetrain has the least resistance, usually in top gear.

[AviatorBJP]

@orbassasin The new setup is essentially what you are saying, with the tire up in the air. The transmission shifts up when the governer speed climbs above a set limit, and shifts down when it drops below a different limit.

Thanks for your comment!

[xubor007]

Carzyest lego invention i have ever seen VERY GOOD!!!!!! AWESOME!!!!!

[zertifikat01]

sry but new one ayn't that beautiful

[AviatorBJP]

@zertifikat01 I know... it is a very ugly contraption.

[yjn504]

Where is input tire?

[deadyou18]

one question .... where u got all thoses gears like spiked whells

plzz tell me

[WpA09]

you earned one more subber :D

[AviatorBJP]

New version comming soon!

[disentis3000]

@AviatorBJP and a ''how to build plan'' ?

[natman48]

wow, that is amazing. very well done.

[Tokatt]

incradible sweet. how did you thought that out?

[AviatorBJP]

@Tokatt

I was inspired by an automatic bicylce gear shifter. It is still a pretty crude design though.

[imthecoffee]

@AviatorBJP But still, that is awesome! I'm inspired. XD

[lilchrispol]

hej!

i have one question

could you make a list of the parts you need to bouild this?

[AviatorBJP]

@lilchrispol I actually can not. This device has been canibalized for the next work in progress, I wouldn't even know where to start. sorry

[headhunta36s]

Oooooyyyp

[headhunta36s]

oooooooooooooooooooooooooooooo­oooooooooooooooooooooooooooooo­oooooooooooo

[headhunta36s]

pppppppppppppppppppppppppppppp­ppppppppppppppppppppppp

[AviatorBJP]

@headhunta36s Do you have a stuck keyboard? Please don't waste cyberspace like this.

[headhunta36s]

@AviatorBJP im sorry man my brother was messing around

[AviatorBJP]

That makes sense. I grew up with a little brother too. Good luck!

[headhunta36s]

@AviatorBJP lol yeah thanks i actually have too -.- lol

[Dragoby]

how did u make that just out of your own ideas or from some sort of instructions?

[AviatorBJP]

This was just a random idea of mine. No instructions. I am trying to improve the design at the moment. Thanks for commenting!

[PlayStationHidden]

this is amazing... maybe when you're done mastering the gearbox, you can build a motor vehicle onto it! you can prolly sell the design to lego too

[ruben676]

hey man nice gearbox but is it possible to make the flyweel system smaller??

great video good job

[AviatorBJP]

Thats what Im working on at the moment.

I have managed to make it about 25% smaller so far.

[corotor12345]

@ruben676

I tried it without success for about year. I am so jealous this guy even managed to make it work properly. Although he did have some advantage over me... I needed too much space to get the RCX motors to speed and to properly engage. I managed third but not fourth or fifth gear.

[wihlke]

impressive!

[Noble909]

I never even thought about doing that way! You're clever...

[AviatorBJP]

Thank you very much.

[MIKSER97]

the best of lego automatic transmission

[rm125srule]

this is one very few working gearboxes that are actually automatic, job well done.

[MegaJabe]

wen ur done dat is

[MegaJabe]

can u show us how 2 do dat?

[AviatorBJP]

Hi MegaJabe. I made a quick how to series that you can see. the first one is titled: "Auto Gearbox Mechanism using Lego Flywheel: Build Phase 1 of 8"

It is kinda boring, so I appologise, but its all there.

Thanks for your comments!

[Jonathanpoll]

@AviatorBJP hey! cool thing!!! can you plz put on a tutorial for that specific gearbox?, it fits perfectly on your model, and i would like to try that. BTW: that white gear you hacve (near the gear lever) do you need it or can you use a same size cog?

[AviatorBJP]

I have actually canibalized that gearbox in favor of a 3+N speed linear gearbox. I have already built a slightly less ugly model of the autoflywheel transmission, but i cant find the cord to charge my camera, so I cant make a new video quite yet.

[AviatorBJP]

And yes, the white gear is what keeps the lever from jamming the whole contraption at the bottom and tops of its range.

[bamper42069]

oh its on a tread mill XD, i was like damn he can move fast and still mess with the shifter

[NOLIMIT69NOLIMIT2000]

That was sweet I so want one.

[bedeone]

That's simply amazing. Very innovative, never seen anything like it. I'd love to see this piece of engineering implemented =D!

[AviatorBJP]

It actually was inspired by an existing system. There is an automatic bicycle gear shifter that uses a flywheel. I saw it nearly 5 years ago, and haven't heard anything about it since.

[AviatorBJP]

It has no power source yet. It will eventually run off of a Lego Pnematic Engine. The power is being transmited in reverse order in this demonstration. The wheels are sending power through the gear box and flywheel to the "input" which is not connected to anything yet. The shifting system has performed identically well with electric motors and my prototype LPE engine.

[LegoMaster739]

thats what i'm doing too!!

do you know how you are going to keep the air compresed on your car or is yours not going to be RC

[AviatorBJP]

I dont have any overarching plans for a finnished car. I just am tackling small things.

My LPE works off of a bike pump that I opperate by hand and the compressed air accumulates in a 2 liter bottle.

I emagine someone could hijack some CO2 bottles and use them to run a LPE car that would make it independant. But I am just happy to use my bike pump.

[jclegoman]

so cool what is powering it is it a running machine?
