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
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.
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.
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.
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
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
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
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
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
I'm thoroughly impressed with the rigor and precision of your suspension experiments. It's clear you've put a lot of thought and effort into this. My back appreciates your dedication to smooth rides 😁😁
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 👍!!!
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)
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.
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!
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.
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
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
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.
Honestly, I like the idea, but without enough weight on the suspension, they will all buck violently when reaching the end of travel, especially when the end of travel is the ride height as most of these seem to be. You can see it in a lot of these where the chassis flexes as much or more than the suspension wants to move.
While I particularly liked the summit seeker as it seems to be based on an F1 car's pushrod type suspension and the overall test was pretty cool I do feel your methodology for the test could use a little more work. Standardizing the ride height of the load would be one example as to attempt to minimize the variability of the moment caused by said height. Another would be testing with different load masses to allow the softer and harder suspensions to shine in their respective areas. Obviously this is just for fun and I am just throwing this out there. Good video nonetheless.👍
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.
Hey my family is brain dead and I picked them up at a local asylum. They believe that you're using cheese cubes instead of sugar cubes can you please help me with their psychological treatment and from us what you're using as cargo?
I see that these are for wheel based vehicles. And I havent heard of majority of these types of suspension. And why I meant by wheel based vehicles, is because there are like 3-4 maybe 5 suspension types you left out, but they are tank suspension. Like torsion bar suspension. I can"t remember the others, if I find the video, i'll come back and edit the comment.
I feel like you would like a game called “Trailmakers” it’s a game about building stuff, like Lego, and I feel like you could like it due to the similarities.
Why were some cargo baskets built with higher sides on some designs verses others?? The higher sides changed the center of gravity, but it also helped with holding more weight... so some designs had almost double the cargo weight then some of the other ones. Some of these versions had the payload at higher heights and some even had the payload suspended by only one side, so it had some bounce. Even the linkage that kept the vehicles in-line and on the treadmill, was changed from version to version... Sometimes it was mounted up high, and at other times it was mounted down low... this would have HUGE effect on the vehicle, especially on the "large ramp" tests... this entire test was cool to watch, but it really wasn't a test... it was just some designs and then one man choosing some random scores, because this was definitely a flawed test... I'm not expecting something crazy, but this wasn't even trying to keep some of the parameters the same from one test to the another...
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! 😊
when doing these tests a control experiment (one without any suspension) would be nice
It would be cool to see you test all the Lego tires 🛞
Summit Seeker but with magnets as the springs.
@RC.Bricks "Brick Test Zone" channel tested different tire sizes
All your videos are so satisfying who agrees with me
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

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

True, but suspensions also get points for “cool factor”. I am sure the test is supposed to be fun, not fair 😊
Mass should also be considered
That poor test driver needs a raise for everything he does for us
Was to be expected that a lego mockery of leafsprings would be that effective. We use/used leafsprings in reallife for a reason.
Bro reinvented my series 2 land rover.

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
Chain Shaker top!!! 😅
Spring Rover totally gives off Citroën 2CV vibes! Such a clever suspension design! 🚙🌀
I thought it was the summit seeker that had the 2cv suspension but the funniest one was the one suspended from chains🤣
Chain Shaker is the ultimate champ! It’s definitely my hero!
I like that the driver kept smiling throughout
🤗🤩
These tests with obstacles are interesting and exciting, I am impressed! 🤗🤩
I'm glad you enjoyed the testing process! 😊
Chain shaker has me snickering while together. It has me balling tears of laughter apart. Amazing model!!
I think the height of the payload made some of these seem less effective than they otherwise night be
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

the boomerang just needs a limiter for the wheel pairs so it doesnt go upside down
Glad to see more Lego suspension videos on UA-cam! Originality is the best part! Awesome job man! 👍🎉
I appreciate your kind words!
No Lego drivers were hurt during the tests. All drivers are real stunts. My fav is the Chain Shaker
So great to see more creative LEGO suspension builds on UA-cam!
Chain Shaker is the best!!!😂😂😂
This content made me curious and excited. you have done very well. Keep up the good work.
Thanks for the encouraging words! 😊
thank goodness these lego dudes have no necks omg the whiplash on some lol. Imagine the Rubber Hopper as an 8 hr shift
I like how this shows, despite leaf springs being cheap old tech - they're actually pretty good.
Ey he brought back the crawl voyager suspension, lesgo
Very clever idea using magnetic poles as springs!
Thanks! I'm happy you found that part interesting.
wow this idea is awesome i will refer to it for my project
I'm glad it can be helpful!
love the leaf spring idea, hopefully lego makes some oil filled struts one dsy
I hope so too! They would make some really cool suspensions.
6:33 But you drop it everywhere, my word. And besides, what are these white cubes? Is it at least eat?
summit seeker is basically just double wishbone suspension
Vehicles with elastic bands really keep balance very well. you're so creative 😄
Thanks, I'm glad you enjoyed the video!
i have been waiting for another one of these videos for a while, thank you!!!
I'm happy you like these types of videos!

BABE WAKE UP NEW DR ENGINE VIDEO
the cranium shaker really likes to spontaneously combust
You're creativity inspires, awesome video! :)
Thank you for watching! 😊
Summit Seeker is the best!
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
The Chain Shaker is transformed into Santa's sleigh
🤣
fun fact boomerang bouncer I'm pretty sure is based off Sherman suspension Look it up.
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!
Thanks for the feedback! I'll keep that in mind for future videos.
Do more of these I like them quite frankly the better Lego UA-camr I've looked left and right for better UA-cam channels in this and I can't
My favorite is Leaf Cruiser.
he finaly uploaded its felt like 2 years since he uploaded im always watching you =)
im creepy am i
Solid axle leaf spring proving its worth once again

Idea. Use under inflated tires.
Thanks! I'll add that to the list of ideas for future videos!
Traxxas is calling their lawyers
6:44 can't miss the delivery 😂😂
Hello, I am from Iraq, I love you
I'm glad you like my videos!
Your video makes me worry! There is no doubt: you and Lego are made for each other😊
I'm glad you like the video!
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
how do you decide which vehicles get a tall fence and which ones get a short fence?
12 a.m., and I'm watching different Lego suspensions
Do swing arms with a shock absorber on the inside to make it realistic. Please see this comment 🙏
Due to the bendiness of the magnets system, the suspension has friction dampening too
My heart is torn between the Crawl Voyager and Summit Seeker.
Cool, may be combine chain with other suspension
Thanks! That's a great idea, I'll explore that in a future video.
good job, bro
Thanks! I appreciate it.
7:00 ooh be careful, Traxxas might sue you lmfao ifykyk
not sure I entirely agree with all those ratings tbh
You gotta make some suspension that is motorisable with the buggy motors
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.
Yeah suspensions are cool, but if you Want so save the most amount of white cheese. The cover lid is best one
Summit seeker looks like it's about to break on it's own weight
Honestly, I like the idea, but without enough weight on the suspension, they will all buck violently when reaching the end of travel, especially when the end of travel is the ride height as most of these seem to be.
You can see it in a lot of these where the chassis flexes as much or more than the suspension wants to move.

@DrEngine No problem. Glad you appreciated the idea. I really enjoy this type of video so keep on keeping on.👍
Easier solution: build a camper shell for the moon buggy... you'll lose less boxes 👍
LIKE if you, like me, rewind to see what those damn cubes are that look so delicious!
Crawl Voyager scored pretty well, but not excellent. Maybe it could use a few adjustments! 🤔 and less points...
Thanks for the feedback! I'll try to make it even better in future videos.
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 chain shaker😂
I like to believe that each bed is full of cheese cubes
5:33 so leaf springs gets one of the highest ratings
why do those cubes look so edible...
I think it's sugar cubes
I like the Leaf cruiser but I don't have this lego parts😢
Well, different wheelbase, different cage height. The comparison is not really worth much
Hey my family is brain dead and I picked them up at a local asylum. They believe that you're using cheese cubes instead of sugar cubes can you please help me with their psychological treatment and from us what you're using as cargo?
As soon as someone writes the correct answer, I'll let you know, but for now, can we leave this as an intrigue?
Erasers?
They look like marshmallows
@@DrEngine Tofu? :D
I wonder if you are adjusting the suspension/damping for each vehicle or do you just build?
6:45 Oh no, it gave in.
these video's are awsome
but the hight of the load also changes how hard it moves
Now I want to have a time machine to be 10 again.
you need to keep them all the same wheelbase for a fair comparison.
well now i want my magnetic suspension to charge my battery
Who do the small blocks remind me of the one blocky gum?
6:52 is this referencing what Traxxas uses for their Summit?
I actually want to know what cubes he puts in the vehicle’s
I see that these are for wheel based vehicles. And I havent heard of majority of these types of suspension.
And why I meant by wheel based vehicles, is because there are like 3-4 maybe 5 suspension types you left out, but they are tank suspension.
Like torsion bar suspension. I can"t remember the others, if I find the video, i'll come back and edit the comment.
This video proves that most used spring suspension system is not a better option.There are better suspension systems than it.
Not necessarily, it depends on purpose and the vehicle
I feel like you would like a game called “Trailmakers” it’s a game about building stuff, like Lego, and I feel like you could like it due to the similarities.

Need more. Suspension ismy fetish.
If the cars were the same only with different type of suspension, it would be more accurate.
