I love how this shows the basic design idea for most manual transmissions, with high and low gear settings and over drive implementations. Definitely a great starting point if you want to learn how manual car transmissions work.
@esp ele He didn’t do anything wrong and you just sit there telling him to shut up. Invest your anger into pumping iron rather than being a keyboard warrior.
Eventually you're going to build a full, life size car out of LEGO that can go 0 to 60 in 5 seconds, and is somehow only powered by a single LEGO motor.
honestly probably doable to some degree if you allow external non lego componets (ie elastic bands to store power.) and only care about the initial burst
What they thought Legos would be: A great toy to help kids learn problem solving and creativity! What it really is: A great tool for much older people to make prosthetic limbs, lego working submarines, and lifesize cars.
I just need you all to know, this is my go-to channel after I get really high and have watched a few documentaries, continue to get high then lose the ability and desire to think. Thanks for making binge-worthy content that is PERFECT to veg out to with a few snacks! Much love from Canada eh? Stay frosty ;)
It is amazing!! Consider that that's basically what every living thing tries to do (in a way), it's interesting to think about! For example, proteins and enzymes are just litte molecular lego building blocks. And cell walls in plants are basically building bricks!
It would be really cool to see a LEGO gearbox with different clutch designs. It would be especially interesting to see if you can make a centrifugal clutch with LEGO.
Seriously impressive. Very cool to see how gear ratios and torque work on a simple scale helping people learn. If only I had this when I was learning how transmissions work
2 years late on this but my father was a truck driver and I was always entranced by watching him shift through his 10 speed on his Semi as a child. Understanding how it works now is still fascinating and gives me an even deeper appreciation of the applied science that goes into gearboxes. Mechanical advantage through a series of what appears so random on the outside, but is actually precisely measured. I love it.
Then no teaching would get done as the tutors would spend all lesson playing with the Lego. The first thing I can think of trying in that scenario would be mixing up gear ratios to try to increase torque enough to push down a stapler with a single motor, I'd then spend half the day stapling a single booklet together. :)
Just a reminder as a mechanic: •Less speed, more torque. •Less torque, more speed. •Gear ratios is how many spins more than the original one(for example 2 gear ratios is 2 more spins than the original)
There are a few Lego automatics around, here is my favorite one. Four speed automatic that shifts based on torque needs. Super clever way it measure torque: ruclips.net/video/YmhiuIRfpbo/видео.html
I built a model of an Allison automatic transmission. It doesn't shift gears automatically though because I don't have anything like a flywheel connected to the output shaft to keep it spinning as the transmission shifts gears. You can see it on my channel.
The 12 speed is like a modern automatic 8, 9, or 10 speed transmissions with planetary gear sets that are selected in different combinations to evenly step up the gear ratio
it's more like the Koenigsegg Lightspeed transmission where there are multiple shafts so you can combine gear ratios. Engineering Explained made a cool video about the Koenigsegg Lightspeed transmission.
8-speed and 12-speed shown here are representative of how truck transmissions work. Your typical Eaton 10-speed (same as 8 but with 5 on each range) has a range selector that works the same way as demonstrated in the 8-speed here. A 13-speed and 18-speed combine that with a splitter that works the same way as the 12-speed that's demonstrated. So yes, an 18-speed is just a fancy 4-speed (or 5-speed if you include the low gear).
Next video: Making an automatic gearbox with planetary gears. The Range and Splitter visualizations certainly helped me as I've used those setups in both the SCS Truck Sim games and in Farming Simulator 19 (with a mod, of course).
@@straightpipediesel That's cool! I use those in ETS 2 and ATS ever since finding out how good they are with the torque multiplier and seamless shifts.
Nice demo, just for info purposes, a typical semi will have a 4 speed split gearbox with a high/low range, giving 16 gears. The 4 gears are changed normally with the stick, the split is a little switch on the front of the shifter knob and the range is a paddle a little lower down. Older semis had some weird transmissions or two with twin sticks.
Now I’ll never loose in a robot battle again. Last time I have a problem that my robot is not powerful enough now I can shift between attack and retreat/escape mode that’s for the great design :)
Would be cool if you would measure the efficiency of the system. Just hook up another motor to the end of it and measure generated power in relationship to the input power.
Worth noting that Speed (in Rad/s) x Torque (in Nm) = Power (in Watts) The only thing missing is the initial speed and torque of the motor. (which you could estimate off the power supply; power = volts x current, but it'll also include the efficiency loss of the motor)
@@phoephoe795 well, to get the motor efficiency out of the way you just hook 2 motors up directly with an axle to measure the zero state efficiency and compare any build system against that. Results in a pretty easy to measure loss in wattage compared to zero state, and a plain efficiency value. But yes, comparing initial speed and torque against ideal outgoing speed and torque and real outgoing speed and torque also works. The power comparison is imo just a lot easier, less prone to calc/measuring errors and results, at the end, in the same efficiency.
I have to say this, I absolutely LOVE this video! It's really helpful for me, as I never understood how a gearbox works. I wish I had the pieces for these at home to construct one! I also love the little shifter, it made me go like "Damn, this guy's gonna make a car out of Legos." Great content, keep it up!
The only difference between this and a real transmission is a clutch, but those rings do a good job at being one for Legos. How would you actually build a clutch out of Legos?
I am a guy in my 60s who still loves thus stuff. Legos, Arduino, other micros, batteries, sensors, etc. I am a Chemical Engineer. Maybe this fulfills my desire to learn more about Mechanical, Electrical, Computer, and Electronics Engineering. Or maybe I am just a kid. Never had Legos when I was young, too expensive.
This video helped me understand gearboxs better, especially with how engine speed relates to wheel speed as well as how torque is diminished as the gear ratio quickens the potential speed of the wheel.
Alright.. I'm just getting into Transport and am currently driving an 8 speed manual truck that has gears in a 'H' pattern, 1-4 in the bottom box and 5-8 in the top box that has a button you flick up/down to change what box your in, and am just begining to get my head around the 12 and 18 speed Non-syncs that have the same 'H' pattern but get the extra gears by being able to go up half a cog and 'Split' the gears and THIS is so helpfull to be able to visualize with the Range changer in the 8 speed and splitter in the 12 speed! Really awesome!!
As a truck driver, I've always wondered how how the transmission works. I can imagine it's quite similar to what you've got here with the 8 speed. My truck has a 10 speed.
ALRIGHT!! You're building engines and gearboxes. Just build a freaking car already. We all want to see it, and we know you can do it. Give the people what they want! 👍🏾👍🏾👍🏾
As a truck driver, this is a good visual. 05:58 8 Speed shows what a typical 8 or 10-speed manual does and 08:29 shows what an Eaton Super-10 10-speed shifts like.
It took me a long time for me to understand how manual gearboxes work. I never really understood until I got my hands on a real one and dismantled it. If this was the first video I saw I would have understood almost immediately.
If you pay close attention you can hear when he changes the gears too fast they grind against each other. This is a real thing that can happen on manual transmission cars. If you don't pay attention to the RPM you can grind the gears. You have to listen for when it's going at just the right speed before changing gear. Most often you need to use a clutch pedal every time you change gear, but you don't always need to use it if you're good enough at listening to the RPM then switching the gear. That's why in the video you'll see him change gear just fine a lot of the time. He changes in conjunction with the current RPM for a lot of the gear changes.
This video taught me more than what I could ever remember from school! If we were taught with legos, lord knows what what would happen next. Amazing vid👍
This is strict educational material of the finest degree. I understood perfectly what a transmission is with this example. It settles the intuition fast with a transparent example.
I’d like to see a gear box with like 100 speeds. It would be an insane amount of work, but would be really cool to see. Needless to say, it would not be broken down and would be used for other videos where it is necessary, like a video where he’s trying to see if legos could break a type of metal. If it’s a really strong metal, like titanium, there could be something within the range of a quadruple crank system, like the double crank system in the video where he sees if legos can break aluminum, except it s a cube and there are 4 cranks, and he uses the 100-speed gear box to power it.

7:45 the reason the clutch exists on manual cars stopping the gears for a second so the synchro's can engage properly
7:50
I still drive unsynchronised vehicles and for the record, a clutch isn't needed, even without grinding gears.
Eventually you're going to build a full, life size car out of LEGO that can go 0 to 60 in 5 seconds, and is somehow only powered by a single LEGO motor.
Nah next he’s gonna make a functioning lego 4-stroke internal combustion engine. He’ll need no lego motors then

The gear grinding... you should make a clutch.
Could use those bulky rubber wheels as clutch pads, spring suspension or pneumatic pieces for pressure?

I suggest you look at some of MaxBrix's videos. He's made a few CVTs which are super cool

@@dhrubajyotisaha8539 That's not how a clutch works. Torque multiplication would be a torque converter
