Tank Suspension Systems - Pros And Cons

Tank Suspension has come a long way from the days of solid steel tracks rolling on the frame of the Mark I tank of the First World War. But today the main battle tank is utilizing a whole host of new and old suspension systems and shock absorbing systems to help keep these heavy and impressive tanks rolling across rough terrain.
No tank is invincible though and even some of the most technologically advanced suspension systems can fail. In this video we discuss SOME pros and cons of the Hydro pneumatic suspension, in particular the Hyrdogas Suspension system of the Challenger 2, and also torsional bar suspension. Both have very good features, but they both have their weaknesses.
What do you think about tank suspension? Is it time for newer systems or do you feel we are doing well with what we have?
Stay until the end of the video and find the small challenge I have set for you guys......... ;-)
Hope you enjoy!

[@herman7661]

Two additional important disadvantages of torsion bars are that they run transeversely accross the floor of the vehicle and the overall height of the vehicle is significantly increased. This was one of the reasons the Brits kept the Christie type suspension for the Comet tank rather than use torsion bars. The other disadvantage is that, although as discussed, torsion bars are relatively easy to replace on an undamaged tank, if you have lost a suspension unit due to a mine or a projectile strike and the hull is damaged, it becomes a major job involving cutting and welding the hull to remove the damaged bar and, if at all possible, to replace it. One important suspension system not discussed here is the helical spring units used by the Centurion and the Chieftain and still being used by the Merkava. These units have the easy replaceability of the hydrogas units but they are cheaper, more reliable and easier to maintain than the hydrogas units, and they do not increase the height of the vehice. They generally have poorer flotation characteristics than either hydrogas syspens or torsion bars however, i.e. the ride quality will suffer, especially at high speed. I believe it is significant that the Brits decided to move away from these units and replace them with hydrogas on the Challenger and the South Africans replaced the coil spring units with torsion bars on the final iteration of the Olifant tank, a modified Centurion.

[@rileymullin6345]

The Abrams uses the bar system. I will agree that it isn't as comfortable a ride as a pneumatic system ( being a gunner on it I get slammed into the sights by new drivers) but the maintenance is very very little.

[@industrialdonut7681]

+Matsimus Gaming do you know how a CVT transmission works in the Type 10 MBT for example? that was something that seemed really cool to me going full speed in reverse, Leclerc needs this. +Vlad Dracula yes Russian tanks have stabilizers even since the IS series of tanks they've incorporated vertical stabilizers on the IS-8/T-10 and that's so much as when 'heavy tanks' were still a thing lol. On their modern tanks though, hell yeah all the more, just search 't-90 tank shot' or search for the T-90 shooting in the air, it can do this and hit a target if the gunner is competent enough.. Like, even the base model T-72 had 2-plane stabilization, not super advanced or anything but it was enough to shoot on the move given that the ground didn't cause the tank to change it's velocity THAT drastically to the point that the stabilizer couldn't keep up.. The thing about stabilization is that, it can get so good until a point, but without the innovations of ammunition to give us longer engagement ranges and precision at those ranges well our stabilizers are just there to allow us to achieve those 'hard-coded maximums' if you will, which Russian stabilizer technology is by all means up to par with. The biggest difference in 'technology' when it comes to Russian and NATO tanks is sensors, such as thermal imaging, and this comes inherently with the fact that those sensors are MASSIVELY expensive and there's plenty of reasons why the US has the highest military budget by FAR of any military on the planet. /rant

Thank you. This is the closest I was able to come to a video explaining how tank treads work.

[@xoonzg4775]

Great video Mats! Nice to hear what the maintenance crew had to say about the suspensions. So a few general things to know: Torsion bar: It's the gold standard of suspensions nowadays. Compared to the Christie suspension it took less internal space, gave better ride quality and was lighter. It is also in general the lightest of the older types of suspensions. But some drawback are that it takes up internal volume and makes the vehicle taller, as well as the torsion bars being a hazard to crew during a blast mine explosion under the tank. And simply the fact that a shattered rod takes a lot of work to clear out and fix. Used in the Merkava is a sort of coil spring suspension. It is extremely rugged (used the the rocky Golan heights) and reliable. The suspension is also said to provide better ride quality then torsion bar, but that is not confirmed. It is also well protected and easy to replace, just remove the module and attach a new one. Also takes up no internal volume. The downsides to the system is the increased weight. Hydropeumatic suspensions or hydrogas are a newer type. They are generally lighter. (Makes up 7-8% of the vehicles total weight, compared to the torsion bars 10%). As well as beings easily replaceable. Well, "easily". They also give you a better ride quality compared to torsion bar, meaning they need less wheel travel (475mm for CR2, 520mm for Leo 2 and M1 and 600mm for Merkava). They can also go into a semi-active or active more, were the suspension adapts to the terrain automatically and the tank can be raised and lowered, changing the ground clearance, as well as kneel to increase gun depression. Another newer prototype suspension is the electromagnetic suspension. Using magnetism to dampen the impact. These are very equal to the hydropeumatic suspensions in performance, all though ride quality should be very slightly worse because of more unnsprung mass. The upsides however, is the easy of maintenance, simply remove the module, with no need for a gas bottle or pump. And they are also said the be 25% more efficient than hydropeumatic suspension when they enter active mode. (The system needs power to vary the stiffness of the individual suspension units.) Another intriguing suspension technology is the adaptive suspension, which uses cameras to adapt the suspension to incoming terrain, and has shown to increase the top speed of tanks. Just search BAE F1 suspension in tanks. Cheers Xoon.

[@alecblunden8615]

Hydrogas certainly gives superior off road ability. As to the correct size of the road to drive on, it's the rightsiders who are being unreasonable. The reason we have islands on the starboard side - right - of aircraft carriers is that it was early discovered that pilots in trouble tend to veer left. The same applies to drivers which is not a great problem if you are driving on the left-hand as you tend to end up on the verge. If you are stupid enough to be driving on the right, you end up facing oncoming traffic and immanent death.

[@prancstaman]

Very cool vid. I made my ptv with air shocks from a minivan, LOL. I went with air shocks because of the adjustable air pressure. Never thought about the ride quality which was like floating on air. A big bonus is, I have adjustable ride heights. I can fully extend the suspension for 12 inch ground clearance for off road, or slam it on the ground with 3 inch ground clearance for a low rider, LOL, by adjusting the limit straps. I also have double wheel bogies which helps with ride quality too.

My 2002 Chevy Suburban has torsion suspension in the front. When I first bought it fourteen years ago, I was a bit leery of that design choice, especially considering it is fitted with a snow plow. I changed my opinion over time. It rides great whether it's on the highway or a logging trail. It has been problem free all these years, even with the added load and stresses of the plow.

[@colincampbell767]

I served on the M60A3 which had a less advanced suspension and even if we were cursing the driver and getting slammed from side to side int he turret - the gun always remained dead on target. And in an entire career on tanks - I never adjusted the torsion bars. And never had one break. I did have several replaced during quarterly maintenance (where things that are difficult to check and rarely fail get inspected and these inspections are done by the mechanics with the tanks crews assisting*). * I was rather possessive of my tanks and didn't want anybody touching them without a member of my crew watching. My attitude was that the only people I could count on to take proper care of it was me and my crew.

Hello Matsimus! I think that road wheel that failed is at 8:50 - 8:56, left side, wheel number 6 (nearest to the sprocket). My reasoning is: 1. Wheel do not extend as much as other wheels; 2. Turret is turned at 6 o'clock in order to provide proper weight distribution for condition; 3. Tank is parking for repair (maybe); 4. Bonus reason - Commander looks pissed off and driver is kind of bummed. Also: Very nice channel, hope to here from you and I like for you to do special video about merkava tenk suspension.

[@TastingwithTonyShow]

The hydro pneumatic systems can incorporate both spring and dampening functions within an integrated unit whereas a torsion bar is spring only. In this case seperate damper tubes are fitted to the suspension arms of some of the road wheels, typically the first, second and last. This reduces the stresses on the torsion bars and on the tracks if the torsion bar is returning from its "compressed" state whilst the road wheel is unloaded i.e. snapping back and over-tensioning the tracks. The addition of damper tubes also helps reduce vibration and create a smoother ride thus enhancing crew endurance. Torsion bars extending the full width of the hull also necessitates asymmetry in the arrangement of road wheels. In the M113 class of vehicles this results in the left track having one less link than the right track (and hence the oft-heard joke that the driver, situated over the left track, is the "missing link"). This leads to the vehicle always pulling slightly left on smooth surfaces and bigger issues of the asymmetric stress on either side of the drive system. That leads to bigger costs as components and maintenance systems have to be tailored for each side of the vehicle. The future: The obvious next-step is an active system that reads the terrain and moves each individual suspension arm such that its road wheel is in the exact correct position to support the vehicle and transmit the minimum dynamic load to the hull when the individual road wheel has arrived over that piece of terrain. That would require a lot of complex computing and that requires a lot of power. Actively moving a dozen suspension arms up and down needs more power. An active system means you're creating some sort of signature that can be exploited, so the requisite countermeasure will use more power. And on it goes................ Ich Dien Sunray11, Out.

[@Real_Claudy_Focan]

i think that japanese (and french) hydro-gas suspension are the most refined ones ! they are more "tunable" to terrain and gives smoothness needed to "hit on the move" but they requires a bit more maintenance Torsion bars are more rugged, less comfy but deal better with rough terrains and are better in off-road situation As always, it's a strategic choice, you must choose the ones which fits your tactics the best Doctrine again ! It's always doctrine of use of the army ! Rugged vs Refined

[@Real_Claudy_Focan]

OR : torsion bars on light tanks ! CVR-T were amazing on rough terrains like the T-90 (which is pretty light for a MBT) AND : hydro-gas on heavy tanks

[@Real_Claudy_Focan]

all fine and complex systems requires good trained crews, hydro-gas are expensive and requires maintenance, if your army can't train crew well, go for torsion bars...

[@renorzeta]

Dude , don't forget T-80 it work with torsion bar splendidly .

[@Real_Claudy_Focan]

it's quite light compared to M1 ! Russians have really good gyro-stabs, they don't need good suspensions ! ^^

[@darklabor]

Well, the french ones are quite rugged, they endure all shocks to the point that it is the hull that suffers from the more catastrophic shocks. During the tank competition in Sweden, the testing crew throw the tank and damaged the hull, the suspension units where fine but the mounting points on the hull where widened. This caused some controversies because, the militaries of the STAT (french army technical section) never reached that degree of pressure even when they sent the tank in trenches with 1-2m jumps at the end of the manoeuver. Recently the UAE tanks that were damaged by AT land mines also have the hull damaged (bearing plate bent, suspension units scratched at worst, and track thrown). A con of the torsion bar system is that, when it fails there are high chances that you have a domino effect with the redistribution of the weight...

[@karlp8484]

The ability to raise and lower ride height, tilt the vehicle laterally and longitudinally gives advantage for hydrogas. Also the torsion bar suspension raises vehicle height because they run right across the vehicle width creating a double floor effect between the belly plate and the inner hull floor (you don't want to be standing on torsion bars right?). But say on the Leopard the main thing that gives it leading mobility are the excellent (Koni) hydraulic dampers as well as the torsion bars. Two systems. Also the tracks (Diehl) are considered to be excellent as well, so need to look at the whole package, when talking about mobility in general.

[@dartmoordave]

I look back on my 10 year career in the Chertsey workshops during the development of Chall1 and the amusement when having a thrash around Long Valley and wondering why the vehicle was drooping a bit on one side. Only to find we had lost a complete hydrogas unit wheels and all. Main problem was you couldn't tell with all the slewing and grinding cross country that it had happened. It certainly transformed the ride from the Chieftain and along with the appalling build standard of the gearbox and the main brakes there was plenty to keep us in overtime. I never really understood why an onboard system allowing the hydrogas units to be adjusted by the crew even while on the move would have given the capability to squat down when hiding to lower the profile and jack back up for cross country. An engineer working with the units said you could loose one of the middle stations but a front or rear was a stopper. Next call to REME to bring a unit and crane. Those suckers were heavy.

+Matsimus Gaming Great vid, it does clear up a few things, ..at least the UK hydrogas is seemingly better than the Chiefy's springs for repairing and the likely safety/sanity measures too in dealing with those multiple springs? ..For all those saying after watching the video X amount of times and saying this or that wheel(s) on the C2 around the 15 minute+ mark, having a wonky wheel or defective suspension, I think Matsimus Gaming did say "..different wheel stations (along the length of the tank; I add) are tuned for different resonances (compression & bouncing/rebound frequencies; I add).." - this is too try and stop harmonic resonance transmitting to the hull and making the crew feel vomity, and when slowing or stopping, enable faster 'settling' reduce rocking. Some of the 'strange angle of the 5th wheel is wheel dirt, + airborne dust/dirt + also down to camera/film quality and resolution, and parallax error from the curvature of the camera lens - as the camera is more centred upon the central front stations. And sorry for those, the UK Hydrogas types are not the same as the Japanese (and possibly the French one(s) too - AFAIK, UK ones is just for the aerogas springing, and not for on the fly adjustment too for height and cant. But as Matsimus Gaming would most likely add, I am likely wrong on even more finer points yet alluded too.

[@dustinshadle732]

we used the same two types under heavy, high end boat trailers. of course the hydrogas setup was all pre set and sealed for gvw

[@Phos9]

Hydro gas suspension has damping built in, torsion bars require external dampers. For a tank it’s usually just a friction snubbed though. The merkava actually uses coil springs, and supposedly actually has the most wheel travel. I think it’s actually similar to a modernized version of the Churchill’s suspension. I think there’s also a system I think called “in arm” that according to horstman’s website (which exists?) is a further development of hydro gas. I think there might have been a different in arm suspension developed as a prototype in the US? The US has this giant kinda poorly documented history of experimental tank designs that never went anywhere.

another downside of torsion bar is torsion bar rock. experienced it on cvr(t) a few times. the best thing about hydrogas is the hotter the units get, the higher the ride hight becomes and the better the ride. driving both afvs is nice, but you can't beat rocking around in an MBT. MENTE ET MANU.

A torsion bar and a coil spring work the same. Both twist when a load is placed on them. A coil spring is essentially a torsion bar wrapped around a cylinder, and a torsion bar is pretty much an unwound coil spring.

An advantage of hydropneumatic over torsion bar is lower overall height. Torsion bars require internal volume which gives extra height to the tank.Hydropneumatic units sit outside the hull so it can be lower.

Hydropneumatic suspension units are only on the outside, thus the inside space cleared can be used for better mine/IED protection.

Transmissions are also undervalued. They're extremely important on a tracked platform.

[@shanerooney7288]

2nd method to test is a torsion bar has snapped: Tap it with a wrench. you will hear a metallic metal on metal sound as the torsion bar vibrates, and you should be able to hear if this sound vibrates along the entire length of the bar. If the bar has snapped somewhere then you should hear the difference. Of course this requires access to the torsion bar. Not sure how easy that is in a tank. In LAVs it requires crawling under the vehicle (something you will be doing anyway).

You should propably have mentioned that torsion bars are just springs. Vehicles using torsion bars also have (and need) hydraulic, mechanical or hydropneumatical dampers, otherwise they would just keep on bouncing. Older vehicles have dampers only on the first (or two first) and last road wheel. Newer vehicles may have them at each road wheel.

levoll11 haha no it's not that one :-) try again and thanks for watching!!

[@tangosierranovember]

Keep this great work up. I really love your vids, especally your tank reviews. Could you maybe do one of the older cold war tanks like the chieftain or the conqueror. Could you maybe also talk once about your time in the british army and in afghanistan.

[@_Matsimus_]

MM S thanks so much! Really glad you like my content! Please feel free to share the video around! :-) I will be doing a lot more tank videos. Once the modern ones are done I will move onto older :)

[@roberth.goddardthefatherof6376]

still a big fan of the HVSS.

[@WAJK2030]

I should give you a "thx" once in a while. Since i like your vlog pretty much. :3

[@_Matsimus_]

Well "thx" for watching.

[@loneranger5349]

Brings tears to my eyes what that tank doing to that road. 😭

[@pauldbeer]

14:39 in video. First tank in convoy. Right front most or first wheel right front. During the turn, the wheel jumps up without any unevenness on the road....

[@orange_phoenix4774]

Great video could you do a follow up talking about bogey and Christie suspension.

[@_Matsimus_]

Orange_Phoenix meh... I don't do much on older stuff but I'll have a think about it :-) thanks for watching

[@marwanalmumin9252]

Hey matsimus. I like youre video's and i think i have found your answer

[@BD90..]

My guess is at 06:30 when you discuss disadvantages of Hydro suspension....the second tank to park up looks like it is leaning to it's right. Everypne has stopped to look and see. I think its on the right hand side the furthest wheel from the camera. The only other possible time i can make out could be 02:55 as there is a crew or something working on the wheels or tracks. prob wrong. lol

[@industrialdonut7681]

Where did all the suspension animations come from? Those were really cool

[@nothingtoseehere1221]

What program did you use to animate the tanks? Tank suspension at work is mesmerizing for me

[@jacobb9365]

Great vids as always ! Shame I can't support you on patreon yet!

[@_Matsimus_]

Spooky Pumpkin you watching is enough support as is :/) tanks so much for watching!! Hope you have a great day!

[@turboconqueringmegaeagle9006]

I'm going to guess 8:04, he has his hazard lights on! looks like the rear right road wheel isn't doing the pushing for the coushion.

[@AngusCuthbertson]

If you look at the tank at 6:05, the fifth road wheel from the front on the right track (crew perspective) seems to have issues while moving. It looks like it's wobbling around. Might also be a Oil patch from a broken suspension that makes it look like it's wobbling.

[@_Matsimus_]

Meridian nope it's not that one :-) someone guess correctly today! Thanks so much for watching

[@AngusCuthbertson]

Matsimus Gaming Thanks so much for making those awesome videos :)

[@hawssie1]

I was hoping for a little more info in regards to hydro pneumatic systems, especially if you have first hand experience. As with the layout and plumbing, wether there are electronics involved or reservoirs of any kind. The torsion bar system on the other hand is elementary. I mean even Chevy 4wd trucks have had those since the early 80s, if you count the S-10, and of course tanks forever,. With the the Gas system I thought it added benefits in regards to real time adjustability and with leveling and raising and hull lowering etc. Then again If I remember correctly that European Citroen brand cars introduced some sort of hydro pneumatic suspension 50+ years ago so neither is really new.

[@aterack833]

16:03, 3rd wheel from front on left side, hanging low and not responding to bumps correctly, may just be defective or low on pressure, but that one has something wrong, also after all the challengers the next vehicle has torsion and it's in tip top shape from what i can tell

[@divinussecreto1068]

I love the M1 Abrams but the Challenger 2 is pretty sexy.

[@_Matsimus_]

Divinus Secreto haha she's pretty sexy I think too. But also a mean bitch lol! Crazy bitch some might say lol. Thanks so much for watching!!

[@Stay_sweet]

How about In arm suspension's Pros And Cons ?? Used to K2

[@kris220b]

what about the coilspring/helical spring used on the merkava?

[@drtechtek2165]

why do they not change all and the rear mechanics charge the hydrogas suspension? Tension bars from experience they could very difficult to take out, because of the angle, that you need to take them out, and sometimes snaps also when the tank is parked, and not moving.

[@2212juanma]

I really like the sleek, simplified presentation of your analysis videos (they're the main reason I subscribed, to be honest). Do you have any plans to explain gun stabilization? Also, sick soundtrack.

[@_Matsimus_]

JuanMa Oliva thanks :-) glad you liked it. I can do a video on it for sure! Stay tuned. Any guess on which hydrogas system has failed in the video?

[@2212juanma]

Oh, man. Um... I'm probably depending too much on my guessing powers here, but I'll go ahead and say it's the vehicle at 6:56, on its right side. I can't tell which unit it is, maybe the 2nd one from the front? The tank seems awfully jittery, considering how slowly it's moving, though. Then again I have no idea what I'm talking about. :D

[@RaduB.]

Hello. I just found out your channel. Interesting stuff. I am just curious if you'll ever tell us which suspension unit failed :-) My guess: 6:00, first road wheel on the right side. All the best!

[@aytonbob]

Torsion bar suspension also requires dampers of some kind rotary are the modern ones.

[@WillTimeAbility]

What is the name of the software you used to simulate the suspension of the Challenger 2 and King Tiger?

[@willrev411]

9:57, station 5 (2nd from the rear) or station 6 (rear). looks to be more floating than supporting

[@_Matsimus_]

William L. Powell sorry no, someone has just guessed right today :-)

[@rappernumberone1992]

Check out the K2 Black Panther suspension system

[@gibbsm]

Are the road wheels on a torsion bar system offset from the opposing side? like are the right wheels slightly farther forward than the left because of the bars not being able to be in the exact same spot?

[@jonny2954]

Yes.
