Hello, I have comments on the issue of spring rate. It is true that we lower the pressure insider the air spring to decrease ride height and increase the pressure to increase the ride height, but that is just for during those processes. Once set on a certain ride height under a given load, the pressure inside would be determined not be the ride height, but by the load. So if the load is the same, the internal pressure is the same. Given that, the spring rate at lower ride height would be higher because the same amount of axial compression and thus the same amount of volume change would result in a greater pressure increase and thus greater restoring force as the volume change percentage is higher. A similar argument would be given to prove that higher ride height would give lower spring rate.
One point you missed on rolling lobe springs is the spring rate (or more accurately, the dynamic force curve) can be tuned by changing the shape of the piston.
p*V^k=const is the basic working principle to consider here. The travel induced volume change relative to the spring volume determines the rate! Rate tuning for different spring heights is of course possible by an altered rolling geometry, but the basic principle is: lower spring = smaller volume = higher rate (Infinite volume = no pressure change = rate zero / volume zero = no travel at whatever load = rate infinite)
please do a third video explaining if these suspensions are good for track cars, daily cars, and sports cars. also why they are or not good. thanks and great video!
would have liked it more if you had touched more on the use of air systems to increase load weights and trailering capacities. Still was very informative and well presented. I stumbled on your channel because one of your vids on rotary engines caught my attention probably because I see my neighbour constantly working on his RX8 and remembered that Mazda used them. Been slowly browsing your channel since. Keep up the good work and thanks!
Would it be possible to have a video about how Blown Diffuser used to work in F1 cars? Hate or love it, the sound it once made was unique and mightyful.
Thanks for the video. I have a bus with FULL air ride. It was a handicap bus with a front kneel feature. When I turn the truck off the front bags completely deflate and “kneels” I don’t want it to kneel anymore. How do I keep the front of the truck up level with the back? What am I missing? Leaf springs?
No, but it is almost certainly way better. And way way more complicated. Introduced in 1955 on the DS model. Even Rolls Royce used it, so it must have been good.
I have two querries please.. 1.Can ride height be adjusted when the vehicle is not on a flat surface or plane?? 2. What happens when there is uneven load distribution Between right and left wheel of a same axle???
I wold like to know what type of air system the ram 2500 and 3500 use (closed or open) I have been told that the system is closed and charged with nitrogen. Also how much weight will the two systems actually lift and the reliability, is there a limp mode if you have a failure on one side or are you stranded?, will a leak turn all kinds of lights on the dash and force the system into limp mode?
The Lexus system doesn't have a reservoir like most Air Suspension. The compressor provides air “on-demand.” Most systems will use four ride height sensors that measure the height and speed of the wheel displacement.
Very good presentation skill and informative video. Sad thing is you mentioned to leave questions here but never answered. Anyway. I got a question. Pretty confident they got no corrosion as pure nitrogen is used in the system. but how about dry rot of rubbers? What kind of rubber are they made of and how long can i expect to use them without trouble? Not extreme weather, i am from Australia. Tubings and fittings also?
are there special considerations and precautions when jacking up a vehicle with air ride suspensions like changing a flat tire or putting it up on jack stands for maintenance?
There is an option on the vehicle menu for "tire Jack" that will hold the compressor from adjusting the ride height. Same goes for when loading and wheel alignment.
Only thing that comes to my mind would be never to put vehicle weight onto a spring with no pressure in it. "Airing up" the spring from this situation could cause damage to it.
They covered it well Robert. Turn it off before jacking it up. Before alignment some cars need to be in a special level mode. On a Land Rover it required a scan tool. Using that mode sets a CEL.
I believe so. I remember seeing a post on the VW Phaeton forums on how to set the air suspension into a service mode, otherwise the car would try to level itself as you jack up the car.
Very good information, should of been a spokesmen for ram lol. Would you know or able to understand if the front airstrut are rebuildable on this ram rebel 🤔
Cool video!! very informative. A bit bias though, asking the RAM engineers is a good source. But one must remember that they are "pro air springs". It would be grate to have a "pro conventional springs" point of view to respond to those questions and therefore get a better idea whether they are worth it or not. Thanks for all your great videos. I feel like I learn from you a lot.
Generally, a hydraulic system such as Citroen's Hydropneumatic and later Hydractive systems work at a high pressue so the suspension components, pump and accumulator (reservoirs) are much more compact. Because lower-volumes are involved, it may be faster than an air system. If the right fluid is used, a hydraulic system can lubricate the pump and valves with the fluid. However, a hydraulic system must be kept clean and needs a sealed system. Air systems have to input a large volume of air to compress it to the right pressure so the pumps have to be much larger. The compressor and valves need a once-off lubrication. Air systems are usually cheaper.
Hydraulics: expensive, adjustable, very comfortable, very quick. Used by the military because of quick adjustability and precision. Pneumatic: comfortable, somewhat adjustable, moderate cost. Traditional: cheap, reliable, not as comfortable, not adjustable. Cost comparisons compare costs for systems of equal quality - cheapest pneumatics will be cheaper than the mid-high end traditional and so on.
2:10 you state that the air pressure between low and high heights are almost the same, as all you have done is increase the volume - but, unless you have a giant skyhook lifting the vehicle up, the ONLY way to increase the volume and height is INCREASING pressure. This is air spring basics.
Great video. We all know coil springs don't have a high failure rate, but what about air leaks in air suspension systems? Is air leak a common problem with them or is it fairly rare also?
The possibility of failure is certainly much higher, as air suspensions have many sensors, an air pump, etc. It probably depends on the specific car, whether or not failures are common.
how are those ride height adjustable trucks managing wheel alignment? do they encourage staying on standard ride height or some magic in place to change toe settings?
do they have some kind of air dryer? in layman terms like drying the air as it pumps it to each suspension? Cause woudln't condensation have some kind of effect of the air suspension system?
Hi! I am a regular viewer of your videos, and really love the technical detail in them!! Since I've become more interested in fitting my future GT86 (The car has already been ordered and will be delivered in January 2018) with an Air suspension (By Airlift Performance), I went back and watched the videos you did on Air suspensions on UA-cam. It all really makes sense what your saying, but what I can't really figure out is how Airlift performance claimes adjustable springrate and ride height. Do they realise this with their "double bag" setup, deflating one and inflating the other to keep the height constant while changing the springrate? It would be awesome if you could find out and make a Video, since they haven't been too responsive. Kind regards, Kai.
@@kaivanderbijl4272 dang, I guess I'm to understand that flat out when you increase the ride height, you increase the spring rate. But I want to know ballpark what those spring rates are. I'm going to try and contact the guy in time attack with the Subaru on air suspension.
Loanword Eggcorn air springs started in racing and were used in the winning champion car for the time attack STI in 2015. so you just haven't read into it much.
Wonderful Madness How many Formula One cars use air suspensions? How many Indy cars use air suspensions? How many Le Mans cars use air suspensions? Answer: zero.

Does air springs work approximately according to Hookes law for a constant air volume and temperature in the spring? (F = k*x) Or does the spring rate change based on the amount of compression in this type of suspension?
You could also see accuairs video with their audi that they show how it handles on the mountain cornering and rough roads and how daily driver friendly it is.
Hi there nice vid , can u give me advice on my problem, nissan interstar rear suspension, pump works great very strong no knocks , but i qas driving along then it dropped to the ground, ive tryed to manual pump it up but the tank was at full pressure, and i jacked up rear end and the wheels raise up with the axle which leaves me thinking theres no air leak from the tank to the bags as the wheels would drop down if air could flow through the system , so im thinking there a control valve or somthing not opening or sumthing
which can be more easily compressed, an air spring or a normal spring? if normal spring is more easily compressible then ride should be more comfortable in normal spring vehicle than a vehicle with air spring
If your engine stops running, that's a horrible defect too. Every system on your vehicle has fail points

7150285 I seen a 97 lexus with a popped air suspension on 1 wheel. it looked like it was in some hydraulic competition. it was towed home because totally not drivable on the freeway or even 40mph.
Hi Mate, can you by any chance explain how some of the new engines now have the "turbos nestled within the V of the engine". These are in some of the new AMG vehicles such as the AMG Gt and the new C63. Also how a car can have two turbos in the cars i have mentioned. Great Videos by the way, very educational.
That is what is known as a "hot vee" V8. If you do a google image search for "hot vee v8" you'll find some pictures that will explain it clearly, since it's difficult to describe in words. Basically, these engines have the exhaust ports facing inwards into the V, instead of on the outside like on a normal V8. It can have two turbos because of the packaging, with one turbo on each cylinder head.
Hey, thanks for the video, but how does damping work for these springs? Do they require special type/design of dampers? Can they be mated to conventional hydraulic dampers as with coil springs? Love you videos, thanks!
All of the above, depends on the manufacturer. Ridetech Shockwave series is an integrated air bag and shock absorber where both have adjustable characteristics.
a 97 lexus with the suspension on high drives like total crap. especially speeding through downtown Seattle potholes, train tracks, and brick roads. just use regular or sport, they feel the same and give a smoother bumpy ride. or just drive a 93 mercury cougar v8 for a nice smoother ride even if ya gotta drive through some grass and side walk on the side of the road at 40mph.
And did you forget to add the fact that most, if not all of them, fail at one time or another, it caused a relative to junk an otherwise fine Sedan De Ville cause it was gonna cost too much to fix and the countless Lincolns I've seen with the rear end almost touching the ground.
+Engineering Explained alright, thanks for letting me know! I'm about to start college to be an aerospace engineer, and I think it would be cool to have. Plus I've learned so much from your videos that I would like to wear something that showed the name of the channel!
Can you do a video about squating trucks?? im thinking about havin my tired sit wider. id like if you could explain it... like wider tires... spacers.. suspension system & how to do it all properly... itd be very much apreciated.
hey I'm a big fan of your videos ..I have some questions on suspension which are not covered in your videos about air suspension ..do you have an official mail id where I can mail them
Weight could also be a factor and to have less to install, you're using the air bags plus installing the airlines, air tank, 1 or 2 compressors and the electronics for the remote.
Yes but at the same time you dont need anti roll bars and you can also maintain a constant higth so can have a soft settup for road use(low speed) and a stiffer settup for track use (high sleep high auro load). overall it adds meny pros and so little cons that I dont know why is not use at all.
Consistency is the issue aside from weight and other extra parts associated. Sportscar ideally uses linear spring (but most still comes with progressive spring rate from factory) for consistent spring rate so the behavior of the car is more predictable thus driver knows where the limit of traction is. Adding an airbag introduces an unknown variable to the spring rate.
Yes, exactly. Conventional springs are more predictable and consistent, which is important for racing. They're also much lighter, simpler and therefore more reliable, which are all very important for racing.
Jes! Have kvestion :-) .. Lot off peaple tels that hydrogen is used to air sunspension.. well then they can col it hydrogen sunspension.. not air :-) ??

The Mercedes 450SEL 6.9 and the Großer both used it as well.
Is there going to be a trilogy of this? :D
could you please run through an example of calculating the spring rate?
Question, Can I control the suspention while I a driving? Or the car must be parked?

The Lexus system doesn't have a reservoir like most Air Suspension. The compressor provides air “on-demand.” Most systems will use four ride height sensors that measure the height and speed of the wheel displacement.
Thank You So Much For The Brief Explanation 💟☮️
How does a compressible fluid give the effect of raising the ride height.
Very good presentation skill and informative video. Sad thing is you mentioned to leave questions here but never answered.
Anyway. I got a question. Pretty confident they got no corrosion as pure nitrogen is used in the system. but how about dry rot of rubbers? What kind of rubber are they made of and how long can i expect to use them without trouble? Not extreme weather, i am from Australia. Tubings and fittings also?
YUNN TUN
These systems operate with air taken from the atmosphere... closed loop systems would require a lot more stuff to operate.
If I lower my car more at the front will I get a lower pressure under my car while reducing drag and lower my centre of gravity?
Nice video!
are there special considerations and precautions when jacking up a vehicle with air ride suspensions like changing a flat tire or putting it up on jack stands for maintenance?

Thanks for all your great videos. I feel like I learn from you a lot.
Thanks, what about the vehicles that have inflatable wheels system that allow to specific wheels to increase / decrease their pressure ?!
Range rovers have this to autolevel the car even during a turn!
Assuming the style is similar, what are the pro and con between hydraulic, pneumatic, and traditional suspensions?

air suspension has constant volume and variable pressure or contant pressure, variable volume??
Great video. We all know coil springs don't have a high failure rate, but what about air leaks in air suspension systems? Is air leak a common problem with them or is it fairly rare also?
Air leaks in aftermarket systems in somewhat common. Factory setups less so.

Did A diagnostic test and I need to buy this part from you.. Do you know where it's located on the vehicle? 2013 Cadillac xts
And this video was totally not sponsored by RAM :))
You're correct, it was not.
+Engineering Explained lol
Why does this matter? The explanation in this video is the same (or nearly the same) for all other types of air suspension, factory or custom.
I know, it's just funny how he mentioned "just like RAM trucks" each time he could :))
Dude, chillax, it was a Joke :D Spornored by Ram or not, sstill a great video. And the Ram itsself is a really good Truck :D
The only Saad thing for me as RAM 1500 Owner that I can not drive with off road set with more than 20 or 80 km for off-road 1 and 2
how are those ride height adjustable trucks managing wheel alignment? do they encourage staying on standard ride height or some magic in place to change toe settings?
The RAM trucks automatically go to "normal" ride height after certain speeds, no matter what height setting you have it at
I like your videos. A little video animation will help to better understand what you are talking about.
Is it good to put lowering spring for a daily driven car
If the lowering springs are stiffer (which is usually the case for properly engineered shorter springs), then the response to bumps will be harsher.
is it similar to a steel spring . i.e. . cutting spring in half will double spring rate .
i envision it to be like a syringe with the end blocked off .
When it is full I can compress it 2cm
when its half full i can only compress it 1cm .
BEST UA-camR !
Could you also make a video about gearbox? I need a 4WD gearbox for 2JZ. :/ i just started to "playing" with cars so yeah.
What is the difference between a suspension with additional small nitrogen cylinder and the one without it??
do they have some kind of air dryer? in layman terms like drying the air as it pumps it to each suspension? Cause woudln't condensation have some kind of effect of the air suspension system?
They're filled with 99.9% pure nitrogen. No oxygen = no corrosion
