Lego Suspensions Survive on the Treadmill - Making and Testing

[@DrEngine]

I’ve built some of the suspension ideas you shared-thank you so much! I’d love to hear more suggestions or feedback from you. Always happy to chat! 😊

[@sumynona.01]

when doing these tests a control experiment (one without any suspension) would be nice

[@RC.Bricks]

It would be cool to see you test all the Lego tires 🛞

[@DRBigADV]

Summit Seeker but with magnets as the springs.

[@denzel-b1w]

​@RC.Bricks "Brick Test Zone" channel tested different tire sizes

[@Thomas-j9r2s]

[@NopeHope999]

[@Cal23636]

You're right

[@ScoliosisMonkey]

Nah,looks like he's having the time of his life.

[@kennethlasseter9264]

ok

[@Floris_VI]

I think the leaf cruiser as arguable the most creative and best performing solution you tried, seriously cool, makes me want to pick of lego technic hahaha

[@Demonoid1990]

No surprise as to why it's one of the oldest style suspensions around. Quite a versatile and simple design, and it works well. My next preferred alternative would be air, which didn't get tested. Hehe trucker through and through here, I drive a tractor trailer for work, and my HD pickup as my daily.

[@alienlobsteroo4882]

Was to be expected that a lego mockery of leafsprings would be that effective. We use/used leafsprings in reallife for a reason.

[@Starfireaw11]

Bro reinvented my series 2 land rover.

[@maitele]

feels like the leaf cruiser's main issue was its complete lack of rebound control. I honestly feel like if it had some sort of shock absorber it would have done much better in all the tests, but especially the drop and small bump tests

[@portableheads24]

@@maiteleyes he shouldve used his magnet stuff as dampers

[@ashgrimstone1818]

Leaf springs are amazing for vehicles with a ton of weight/stress being put on them. Stupid simple and the design means they tow amazingly.

[@jeffreylove5127]

To make the tests fair, every vehicle must have the same wheelbase length and the same wheels size

[@ArdanZima-xj4yz]

+

[@Argun1001]

In addition, every vehicle's cargo-bed should have the same length/width, as well as the spokes of said bed being the same height. I noticed it changed a LOT throughout the vid.

[@mikey111482]

Exactly what I was thinking. The only variables that should change are method of suspension and ground clearance. Weight of vehicle kept within a reasonable range would be nice, too.

[@iRasmus4]

True, but suspensions also get points for “cool factor”. I am sure the test is supposed to be fun, not fair 😊

[@stevenboelke6661]

Mass should also be considered

Geometry types: 1. trailing arm 2. still trailing arm 3. pendular bogie 4. back to trailing arm 5. I guess this is closely related to a strut geometry like macpherson? 6. "Tatra"/swing arm suspension 7. differently sprung swing arm 8. live axle with leaf springs 9. I guess we're back to trailing arm 10. uhmmmmmmmmmm suspended cabin? 11. double wishbone

[@holnrew]

I think the height of the payload made some of these seem less effective than they otherwise night be

[@fusionwing4208]

That and how the payload was stacked up, sometimes the pieces were a bit off center and fell off more easily. Also i think this payload was oversized, if it sticks that far above and your going through rocky terrain, cover the payload or deliver less payload xD

[@LutraLovegood]

Lego even made nets to secure that payload!

[@Mikepet]

You have to watch out, It can really depend on the lenght of the Vehicle how good the suspension works. It distributes the forces over a longer distance

[@sindigunston7087]

Spring Rover totally gives off Citroën 2CV vibes! Such a clever suspension design! 🚙🌀

[@MarcGini-i2j]

I thought it was the summit seeker that had the 2cv suspension but the funniest one was the one suspended from chains🤣

[@JackCreator73]

Amazing suspenstion test, but here is my own rating: Chain Shaker Polarity Pathfinder Summit Seeker Shock Strider Leaf Cruiser Boomerang Bouncer Crawl Voyager Rubber Hopper Magnetic Maverick Elastic Explorer Spring Rover

[@SWellWellWell]

Chain Shaker top!!! 😅

[@backupcreator73]

Chain Shaker is the ultimate champ! It’s definitely my hero!

[@burg0110]

I like that the driver kept smiling throughout

[@joshpost4886]

Chain shaker has me snickering while together. It has me balling tears of laughter apart. Amazing model!!

[@Unorthodox_kidd]

1:20 its also so long that the bumps cancel out the roll factor. Idk if that was part of the test or if we are only testing the suspension

[@Altronn]

As a connoisseur of cheese with a vested interest in transporting my own inventory, I have two statements: 1. Why is the cheese unwrapped? And 2. Never overload your transport past the top edge of the truck bed

[@monstercameron]

the boomerang just needs a limiter for the wheel pairs so it doesnt go upside down

[@SimplyMyBuilds]

Glad to see more Lego suspension videos on KZbin! Originality is the best part! Awesome job man! 👍🎉

[@DrEngine]

I'm glad it can be helpful!

[@Lordodragonss]

Amazing video! SO much work went into this! And so much cleaning xD

[@Microwave200]

I think It would be pretty cool to make some robots, like maybe a tall quadrupedal walker robot but with REALLY long legs, a speedy scuttling bug like robot with 6 legs and if you want a big challenge, make a bipedal robot with his arms being all floppy giving them secondary motion (I.e motion not caused by engines but with handy physics laws doing what they do best)

Incredibili le leaf cruiser che praticamente sono il sistema delle vecchie balestre nei camion ed auto...Forse il fatto che siano in questo caso molto morbide aiuta.. Comunque resta un risultato eccellente per una tecnica così vecchia...Bel video complimenti 👍!!!

[@DrEngine]

[@mr.cutback3642]

Really cool video, the damping factor is very important for each one of these breaking systems. Technically all of these methods of suspension could achieve vey similar results, with the correct leverage.

[@Dashe-Dragon_MC]

The Chain Shaker is transformed into Santa's sleigh 🤣

[@stanleysarjali8108]

No Lego drivers were hurt during the tests. All drivers are real stunts. My fav is the Chain Shaker

[@xnicklc]

Summit Seeker is the best!

[@JessWLStuart]

Very clever idea using magnetic poles as springs!

[@DrEngine]

Thanks! I'm happy you found that part interesting.

[@Lapizzz-GD]

The cool factor is purely subjective . give the driver a 100000000% raise he does so much for us it’s only right to do so

BABE WAKE UP NEW DR ENGINE VIDEO

[@HoleHoleKEITH]

summit seeker is literally just a traxxas summit, dude isnt hiding anything 😭

[@Nic-uk9cf]

12 a.m., and I'm watching different Lego suspensions

[@lacucaracha111111]

Due to the bendiness of the magnets system, the suspension has friction dampening too

[@TheOtherGuys2]

One that I've used is to have the wheel base connected to the body of the vehicle by a single long axle piece. The axle goes through some pin holes to keep it in place, but it only connects to a + hole on the ends. So, when the vehicle hits a bump, the suspension comes from the axle twisting along its length. Is that good for the piece? Probably not. But it's working, and as long as the vehicle stays balanced, it doesn't twist when it's at rest.

[@4workethic]

The leaf cruise was very realistic moving, I might even try that design on a technic truck.

[@naazdeepkaurs.simranjitsin3252]

6:44 can't miss the delivery 😂😂

[@NickSmeltzer-m4m]

Another thing that should be considered is the center of gravity and suspension travel and angle, those will completely change the way the vehicle behaves

[@nativepride101]

Leaf springs for the win. Classic basic design. Double wishbone long travel. Low fenter of gravity "summit seeker"

[@johnrushman1586]

For some odd reason. This video made me laugh my ass off. Lol

[@ЛидияПопова-ч7и]

Your video makes me worry! There is no doubt: you and Lego are made for each other😊

[@DrEngine]

I'm glad you like the video!

[@LutraLovegood]

Chain shaker would work better if the chains were connected to two posts and not just the cab. So chain A goes from post A to cab to post B, chain B goes from B to cab to C, and so on. And then you can try a cross pattern where A goes from A to cab to C, etc. CF how suspended bridges work. Would need longer chains, or ropes, so the studs don't collide with the cab. For the magnets Lego used to make magnets (73092) and magnets holders (2607, 2609 and 2609a/b/c variants). You could make an entire video just using aftermarket magnets comparing different size of magnets and configurations and how they can be paired with more "normal" suspensions, I don't think I ever saw anyone else try magnets for suspension. Which has me thinking... Is it possible to make a levitating Lego train?

[@DrEngine]

Thanks for the amazing suggestion!

[@waterhouse235]

Cool, seems like the longer wheel base designs work more effectively

[@MoviesFanFacts]

Crawl Voyager scored pretty well, but not excellent. Maybe it could use a few adjustments! 🤔 and less points...

[@DrEngine]

Thanks for the feedback! I'll try to make it even better in future videos.

[@Nick-ih3hr]

Cool, may be combine chain with other suspension

[@DrEngine]

Thanks! That's a great idea, I'll explore that in a future video.

[@KamdenKessler]

Do swing arms with a shock absorber on the inside to make it realistic. Please see this comment 🙏

[@new-sunny]

Wheelbase changes in small cars may have more impact on stability than suspension changes

[@hecticaperture]

Chain shaker by far the best one what a feat of engineering

[@MBr397]

Would have been a lot better if you used the same container to hold the foam in and used the same car!! Some of the cars had so much wiggling going on they shook the foam out of the box!

[@MaryShipman-s3d]

fun fact boomerang bouncer I'm pretty sure is based off Sherman suspension Look it up.

[@Johnald_mcfucknuckle]

Nah Sherman's use either HVSS or VVSS, both arms of the bogie are connected to a volute spring, either vertical or horizontal. I think the boomerang is just a basic bogie

Summit seeker looks like it's about to break on it's own weight

[@woaminibricks]

good job, bro

[@DrEngine]

Thanks! I appreciate it.

[@NickSmeltzer-m4m]

I feel that some of the suspensions can be improved by the car's design as it plays many roles on how the suspension works

[@benpaterson2237]

My heart is torn between the Crawl Voyager and Summit Seeker.

[@leonb.3792]

great video, I love it, but u schould show car without suspension too

[@DrEngine]

Noted!

[@dazley8021]

It's less about what suspension type you use and more about the geometry of the vehicle, I mean besides the ones that actually dont have any shock absorbtion, obviously.

[@thatonetelephonepole246]

Idea. Use under inflated tires.

[@DrEngine]

Thanks! I'll add that to the list of ideas for future videos!

[@Mr_Sage]

Chain Shaker suspension is best 😂❤

[@Revenant7n]

"A rubber band can be placed in tension across any two anchors" "Ah, yes, but why don't we place it in tension between an elaborate and weight guide rod that adds no functional benefit while adding size and mass??"

[@JeepnHeel]

This was the inspiration I needed to finish off my jeep. I'm going with crawl vovager, so I guess the next step is to buy 6 more wheels

[@DrEngine]

Glad to hear it! Hope your jeep turns out great!

[@imageetsonetplus]

[@nathanhelmburger]

Boomerang needs three wheels per group so they can flip and stay symmetrical! It's my fave

[@M23188]

Du machst so coole Videos

[@young-aviator]

You gotta make some suspension that is motorisable with the buggy motors

[@eekee6034]

Fun to watch, but I don't get how the reliability is measured. ... Except for the one wheel that fell off and the other one that fell apart entirely! 🤣 The Boomerang Bouncer would have big trouble if its wheels were powered. In each pair, the torque of the rear wheels would pick up the front. It's like a wheelie but with far less torque because it lifts the vehicle much less. If the wheels are connected with differentials, it'll only need to pick up the front wheels of each pair a tiny bit to lose power, all the power going into the lifted wheels. It was a problem with one truck in a trucking game I played. I guess the solution is not to use differentials between each pair, perhaps using 1 diff for 4 wheels and driving the rears from the fronts with a chain or whatever.

[@DrEngine]

Amazing! Thank you for the comment ☺️

[@bambi5490]

the leaf crusier at 5:26 is basically just the solid axle (aka dependent) suspension
