- Far from finished... This was in design stages.
The pinion rolls out due to the geometry of the bars, which was corrected.
3-25-2021 Update. Im going to do another one soon to show some of the differences.
If this was 10 years ago and I'm just seeing this now......what's it look like fully finished????
As Leno would say, “kinetic art.” Beautiful. Congratulations!
Is good to have some springs left so in case of a problem the vehicle wouldn't collapse...
Do you hear any binding up? Nope, thats a badass setup right there ! This is what cool looks like kids . . .
Damn! Nice rod suspension system design 💯💯💯💯
It's dope and cool👌👌👌
I was amazed with the technology of today and change so quickly, thank you
Clean, Clean install, hopefully the articulation wont be a problem, had that myself, high drives are a pain to get into without it. Great job.
Art work in the Best
Beautiful work
Thats a clean and sick bag system design and lay out.
So is this for a car? When the bags inflate, they're going to come through the rear floor?
My thoughts exactly...
Good Point Fell'a
This is exactly what I was looking for. Going to build my dream car since no one makes it.
Hit a big bump and snap the welds off that "tab" on the frame the airbag is sitting on...
masterpiece , masterwork
Manos abiles,e ingenioso artífice,que te duran los de la general motors company!!!!!felicidades y adelante con ésas modificaciones ,esperando que sean de la misma calidad y manufactura también la carroseria,*.desde mi México"*lindo y querido...
SOME CRAZY TRAVEL THERE BRO. OMG LOL very nice once i get another truck i'm gonna put a quick system on it with s body drop, then down the line i'll go all out full truck customization.
Love the design, would only recommend installing bump stops on axle as well just as a peace of mind lol don't wanna come down on that frame or that axle too hard
A lot of air bags have built in bump stops. As long as you build everything to the correct tolerance, you shouldn't have anything hitting. The front & rear bags on my truck have internal bump stops & I have adjustable speed control on my exhaust valves which helps a lot with cushioning bottoming out.
Pump up the jam... Pump it up!
Полный кайф когда смотришь на людей с умелыми руками👍
Love the design 👌, I'm wondering how much weight can you put on the truck for that bar across can hold!?
That depends on the airbags rating.
thanks for taking the time to post this, really innovative design.
one thing- it looks like the entire load transfers to the center of the lower links.. any issue with bending?
it depends on the set up and products used. usually its just like having a tire blow out. it pops you slow down n pull over on the side of the road.
Шикардос
Looks like you're going to have quite a change in pinion angle
Looks like an ancient AnyLevelLift
I think the cross beam is a little light and will be the weak point. Still like it lots though
The cross beam is built stronger than 99 percent of most vehicles on the road. 1 1/2 quarter wall DOM.
Reminds me of my Citroen BX I had 30 years back. But this one is on steroids. Air suspension gives a rantasticly smooth travel. Potholes just get eaten up.
That's a sick set up I can't wait to get mine done but I don't know how I want to do the link system
Is this some sort of Lo-Rider after-market kit for American cars? No-one else would bother with some sort of height-control on a live rear axle. If it's supposed to be "new and innovative", I'd suggest you look at the 1955 Citroen DS, which had hydropneumatic self-levelling and height-adjustable all-independent suspension, with centrepoint steering geometry so you could brake in a straight line with a front blow-out with no hands on the wheel. And, for James Merkel, the ground clearance WAS adjustable from 2" to 8" front and 2" to 9" rear.
Nothing was implied for this to be the first vehicle with adjustable suspension. It put a new spin on true cantilever suspension. In your world, from your point of view, yes, it would be called a lowrider.
We use air and hydraulic suspension to lower and raise vehicles both for leisure, commercial and handicapped use.
He already said it won't go that high with the frame on it...very nice fab work
It will bend where the tiny pipe is and the frame will twist because air bags generate torque. Probably the bolts where suspension arms are located will snap after few years. Buy Yourself a book on suspension designing and re-learn everything You know.
Holy pinion angle Batman!
Yea it got really bad there at the end, Lol. That was at 18 inches of lift. It never would have lifted that far, but the bar length was changed to fix.
rilly slick, very nice consecpt, A+
Ogólnie super pomysł, ale chyba dostrzegam pewien problem z pochyleniem się mostu przy podnoszeniu ramy.
Wał napędowy będzie zbyt nisko od ziemi, co może spowodować na przykład ocieranie o asfalt?
How did you get those scooter tires to do that
the weight is split between air bags and directly on the axle, how about vibration and the welded parts?
It's low rider suspension what can you expect
Well there are rubber bushings so I would expect some sort of damper
@@mackasmachineschannel3522 they use cantilever suspension in race cars so what would be the difference
Nice design.. where is the exhaust pipes going to run though?
question i noticed the angle of the rear differential changing as your aired up the shocks would that cause problems with the drive shaft or not
The air bellow works as a shock absorber AND as the suspension
Nice design intent of the arms, pinion angles are destroyed though.
I will use this on my truck thank you (profile pic)
Do you have problems with pinion angle change?
Hermoso.
Gracias por el vídeo amigo mio...
Saludos desde viña del mar Chile...
thats fucking kewl, could look at that fab work all day
Impressive design, thanks for uploading.
Отличная работа!
If you look close you'll see there is one on both bags. They're for keeping the upper bag bracket in the correct alignment through the whole arc of travel.
Very cool! And how did you decide with the cardan? In a low position, it will definitely interfere!
I SEE THE TOP LINKS ARE TO SHORT ON THE 4 LINK,THE DRIVELINE ANGLE LOOKS OFF
that is just beautiful nice job
its amazing great work 👌
I don't think the cross pipe is Evan close to being heavy enough to handle the loads. In my opinion
Awesome setup.
nice! realy! but dosent the diff angle moves the wrong way?
Yes, but normally you would not be driving long distances at the max height. The pinion angle needs to be a couple degrees nose down anyway.
How well does the suspension articulate? Looks rather restrictive with regard to body roll/movement. Looks nice, though...
it is probably the best u ever saw
@@nikki2708 and you're basing that on what, exactly?
Because u she just look at it more and realize
@@nikki2708 so you can't answer the question. That's pretty much what I figured. :)
Is it OK that the wheelbase changes so drastically with travel? Longer link arms would minimize this.
Wont be a problem, the distance changes even in stock configurations, but at a lot less than this. The input yoke on the drive shaft is designed to "lengthen" itself with up and down travel. Also you wont always have it at that level.
Do you make after market frames for square body gmc trucks, that can handle,horsepower
I think the bag arm is going to tear the tube apart.
kinda looks like the wheels will go backwards relative of the bed...if it was ever put on.
Good job
Cool design but How would that system fit under the floor pan is what I want to know? Who needs a back seat right?
Will That be Stable at High Speeds Cornering
Those are dominators
I want the Jeep ppl car to eventually hve a suspension that can range from 2" of lift to 4 or even 6" of lift. On road vs off road safer ride & still plenty of clearance what ever tires u decide to run & beefy control arms that can allow the travel yet keep the geometry needed to hve full control. This seems like the perfect solution.
There are alot of rock crawlers that use adjustable suspension.
Were building a 79 Bronco now that has big Danas and Adjustable suspension (airride)
Do u guys just build mini truck chassis? If not im looking too get in the auto cross scene with my 78' chevy monte carlo
How about propellershaft? in lowest position there will be obstacle
Excellent fab work
the lower link is not able to carry the weight.
Looks like it would be infinitely stiff in roll.
Good Job Boss
So cool
Nice Thats A Sick Setup
Great setup guys. Looks and works killer. You guys selling this setup?
Good job !!!
theres this thing called pinion angle geometry you jave to keep all the way thru the lift.. guess its back to the drawing board
the pinion angle started going awry at about 15 inches of lift and got worse from there. It never would have used that much lift, but the geometry was corrected.
Very nice
muy buen trabajo good job
someone did a great job but wheres the SHOCKS at ?
Top mechanic
Lower jet thrust bent. W- shaped transverse tube too thin. Support under the cushions need to do on a common platform.
Impressive design,
Hi this is Kumar from India I want modify air suspension my vehicle auto rickshaw for three wheeler how to modified my vehicle auto rickshaw please get I want air suspension
Top !!!!
NICE one...!
This system is good
Wonders of mechagastronics woww.
I made same let see this out.
Top class work
I love this setup. Would love to have it under my 65 c10.
How much for a chasis like this one?
That is very interesting.
@KeithWasHere1 They look like Firestones maybe?
that crossmember is gonna break if that thing actually gets driven. cool concept tho.
how do you figure?
@@smithchassis you have a single piece of tubing supporting the entire suspension with no gusseting or reinforcement... and not only that, its taking force from the weight of the truck, which is pulling upward on the bar at lift. At the same time you have a 4 link bar on there, which serves thee purpose not only of centering the axle, but of controlling axle wrap, which is a torsional force that is going to be applied to that bar on acceleration, and the stress points are within a few inches of eachother. There is also a certain amount of torsion put on the bar from the cantilever system, Albeit, it is largely reduced by the links you have, which keep the top plates in line.. But unless every angle is PERFECT, there will still be some residual torsion going on there... The suspension is literally going to try to tear that bar to pieces under hard acceleration. This setup will work great if all you ever plan on doing is driving on and off the trailer, but if you're trying to build something that will withstand daily driving,.. this isn't gonna last, especially if you plan on putting any power to that axle.
I understand what youre seeing from your point of view, and you arent completely wrong. We over build things, and this was in the design stage. The tube itself is 1.5” DOM .25 wall, and it acts solely as a pivot point. It bears some weight but the weight is spread out over the bag mount, the pivot point and the upper bar.
There were also more crossmembers added afterward.
Ill be updating this more often, check us out facebook/smithchassis. also on IG.
Thanks for commenting!
ya whats up with ujoint angle/yolk
Гениальная кинематика! Жаль, туда почти невозможно установить амортизаторы.
...
Халигали надо как у уазика старого,рычажные
а то, что нижний рычаг пополам сломает на первой кочк никого не смущает?
@@ЕвгенийАврамов-ч3о да какие там кочки, это ж для понторезки лоурайдера всё придумано, они брюхом любят ползать.
им слово практичность чуждо)) я говорил лишь об уникальности схемы, ничего боле ...
@@ПавелКостерин-к6т а ничего что там тупо рессоры и одна поперечная тага?! где ж ты там рычаги нашёл? 😱
What size is that frame 2x4?
верхние тяги к мосту располежены под углом для предотвращения смещения моста в сторону??
Will this work for side to side? "airing up only one bag".
these are nice to look at but not good for the road.
big scott you going to have to defend yourself on that statement why do you believe this sort of suspension wouldn't be good for road travel
How much does it cost?
2x3 steel cantilever bars all mounted on a 1 and 1/2 inch? diameter bent steel tube I hope this "killer setup" stays in the garage... seriously that's dangerous we use that diameter of tubing to mount shocks and your hanging the entire suspension off it???
whos we? I drop trucks from 6 ft in the air onto the ground on 1 1/2 quarter wall?
Insane travel. whats the purpose of the dogbone link on only one bag?
I can tell it's on both. look for the shiny nut right above the airbag.
I will go back and look, is it a pan hard bar?
