7 Brake Mechanisms in LEGO Technic

[@MrDgwphotos]

#5 is also known as a speed governor. #7 is used on diesel electric locomotives as a secondary method of reducing speed on mountain grades, it's known as Dynamic Braking, though it's sometimes an optional feature, a railroad that does not have mountain grades may opt to not buy locomotives equipped with dynamic braking.

[@Elliottblancher]

@@MrDgwphotos it's mainly the Railroads that run through the Rockies

[@lsp6032]

also, not just dynamic braking for locomotives, purely electric trains can modify the same setup to allow the generated power to be returned to the grid, allowing regenerative braking which quickly slows a train down, especially effective if used with a multiple units which instead of a locomotive, the passenger cars have motors installed below the passenger floor, which used way more motors than a locomotive in total

[@MrDgwphotos]

@@Elliottblancher Actually, it's far more more extensive and common than that, lots of eastern US railroads have bought locomotives with dynamic braking.

[@Soporbum42]

If you take #7 another step further and power the motor "backwards" against the rotation of the flywheel, you've recreated "dynamic braking" as used by modern Diesel-Electric Train locomotives But you're gonna need a bigger/faster flywheel for it to not just spin backwards instead 😅

[@jackpomeroy5855]

I gotta say, you have pretty great ideas when it comes to Legos

[@JpFarms140]

Nice drum brake example but how most drum brakes work is you have the drum that spins around a assembly and have pads that push into it so you have more break area for less space

[@Frank-mn4hx]

The disc brake is not only for cars. Also bicycles use the disc brakes. The version that uses oil instead of cables. Powerful and easy to adjust. One of the best brakes for as far as I know.

[@caiwilkie6453]

the gear reduction in the motor is doing all the braking force

[@CenReaper.]

LOL. And the spring isn't the most efficient energy storage neither

I can see that you are Japanese 👍

[@RavenTheA2]

The last one is also pretty commonly used on diesel- and full electric locomotives

Ur videos are so interesting, love the content! 😊

Thank you :)

I read the title as "Diss Drake"

[@JulesGryczewski]

You should make a truck with a heavy load and test all of these brakes on them Keep up the good work 👍 💯

[@Slav729]

You should try to make a vehicle using these breaking systems!

[@in1]

Jup, most kinds of Lego vehicles have a builtin #7 tho :)

[@Slav729]

That's cool!

[@duncanurquhart5278]

(usually with a larger disc)

[@AWizardAndaMouse3432]

Huh, I’ve wondered what a Lego drum brake would look like.

[@joelpaultre7440]

I'm sure that this has been saud elsewhere but the drum.brake you made is closer to a band brake which was an early idea used on cars that tightened a high friction band around the axles of the vehicle. They weren't used for long as they only stop well going forward and barely if at all work in reverse. Also fun fact about drum brakes, it is illegal for a car to be made using drum brakes in the front given their significantly liwer stopping power when compared to disc brakes

[@diezelleprozo6047]

i love using Lego Technic in applications like this. also, maybe i could suggest a different format for the transition text? usually, it's just a simple fade in and out, but wouldn't it be cool if it looked like it was typing in the text during the transition? i don't know, i just like coming here to this channel often to admire the usage of Lego in practical applications.

[@in1]

Thanks! I have a pretty bad editing software and I'm not sure if that's possible, but it sounds fun

[@chrismayer3919]

When you say you give People a brake… YOU MEAN IT! 😆

[@TheHeavy-r8t]

Disc brakes on modern cars are very useful but however the components wear down over time, in the disc brake example that you've shown, you have used rubber pieces which isnt really the best way, because these rubber pieces will also be subject to wear and tear and the mechanism to trigger the disc brake is not optimal, as in modern cars the disc brake allows for some movement such that the car doesnt brake too abruptly or too slow, the faster you brake the chance to break components becomes too great, the slower you brake the more you wear down components, typically brakes compress down slow enough but fast on the disc ensuring that nothing snaps under stress and maximize lifetime of the brake pads.

[@in1]

The best way to solve all these problems would be to just use eddy current to brake. But I still think what I did is fine, maybe the braking deceleration isn't perfect, but it works as a demonstration.

[@dylanromine4101]

As a mechanic who doesnt like fixing his own car all the time ive found that hard braking wears out brake discs and pads much faster than gentle easy braking

[@joelpaultre7440]

Another factor that if the vehicle stops too quickly and the wheels lock up before the vehicle stops you lose steering and traction, which is why ABS systems are included in vehicles.

[@사교육세상에서살아남]

Your ideas are soooo awesome!!!!!!

[@in1]

Glad you like them :)

[@randomqrcod.e]

Hey welcome back

[@OutDated.87]

I have a question about the kinetic motor you're using. Is there a limit to the power you can put into it? Like, will it damage the motor if there is too much kinetic energy being stored? I am asking this because it appears that the motor is low powered when you are applying the breaking mechanisms. Was this by design, or is that just an unwanted consequence of having to apply the breaks after releasing the ratchet lock, mixed with the sudden release of the kinetic energy stored in the motor?

[@in1]

The motor does have a limit, you can turn it until it makes a pretty unpleasant sound and then it stops. In the test setup, I'm waiting for the motor to put all its energy into the flywheel, so that there's not only the spring inside the motor pushing against the brake, but all the energy that was stored in the motor.

[@wasnietak4919]

I have tomorrow test and Im watching 7 types of brakes in Lego Technic, genius

[@cheesywaffle6761]

How'd it go?

[@Bean-ie_Official]

please make an easier clock tutorial, i just don't have the pieces for the other ( love the chan btw)

[@in1]

Well, every kind of flywheel works if you find a way to spin it fast

[@STA-3]

3:42 It looks more like a Hug Brake :D

[@in1]

awww true

[@DmitriHarizanov]

and then on bricklink a new listing for "used parts" )) while a lot of the parts were clearly damaged.. the joke aside - great video! imho - all the methods that were shown here convert the energy one way or another into heat, even the last one with the PF motor generates heat within the motor

[@in1]

Yeah, the electric part is prolly smaller. But it works as a proof of concept.

[@skylinedatsun]

Cool

[@heho1]

cool 👍

[@chahghg0]

no eddy brake?

[@in1]

Would be pretty impossible to build with Lego parts. But theoretically electromagnetic friction is the principle of #7, so there are similarities.

[@GeneralPurposeVehicl]

how did you break so many parts? I noticed many are cracked.

[@AIDOSER]

What about air brake? 😁

[@IWhiteTigerI]

#5 is literally ABS

[@AbdullahGebi]

[@GalaManna]

The drum brake reminds me of an e brake just saying okay....................

[@joelpaultre7440]

Your emergency brake is just a second method of applying your brakes in case of hydraulic system failure. It uses the same stuff its just fully mechanical instead of hydraulic.
