Instead it has rigid tubular backbone around which can every semi-axle pivot independently reducing movement transfered to chassis.

The biggest advantage of Tatra is that it has a torsionally stiff chassis based on a central spine with independent wheel articulation via swing axles. The MAN like most trucks has an independent ladder type chassis that is allowed to flex (the Unimog uses this to incredible effect) but necessarily means that the ride is compromised and the cab has to be segregated from the chassis, usually with its own suspension.

[@Sir_Lauchboy]

This test didn't say very much about quality. Tatra just had air suspension and pretty every test was suspension based. What about engine lifespan, max load, max speed, drive assistance, safety features, fuel efficiency, maintenance cost and many factors more?

Tatra are all-wheel drive with swing-axle independant suspension on every axle. The chassis is a body length massive tube that contains the transmission shafts that go from axle to axle to axle. Up to four axles on the largest standard chassis, with special chassis' with even more. Early Tatras had air-cooled V8 and V12 diesel engines, with more recent versions using modern water-cooled power plants from European manufacturers. I'm not certain, but I think they have diff-locks, but I cannot be sure. They have the usual tyre inflation systems for on-the-fly pressure regulation, and use unusual tyres that have harder rubber compound on the outer edge, so that unladen, when the axle is lightly laden and the axles a swung downwards at an angle, they tend to drive on only the outer edge of the tyres. The rally trucks adjust the suspension, particularly noticeably at the front, and lower the height, thus causing the wheels to angle outwards at the bottom so that at full lean on corners, they're pretty much upright and giving the best contact patch. The system was designed by Hans Ledwinka in 1923, and continues largely unchanged to this day. Many years ago when Tatra still made cars, I was involved with the British design team, led by Tim Bishop, who brought the cold-war Tatra 613 up to Euro-spec, with a fully compliant engine, 30% more power, and a top-spec luxury interior. The last Tatra cars, after our contribution, had a body redesign, some even had Porsche engine barrels to increase capacity yet further. All Tatras were rare cars, and are highly collectible these days. I also worked on the 603 'spaceship' sedans, as well as war-era T87 sedans (which were extremely fast for the day, the one I ones I worked on could do around 100mph a drove much like a modern car... except that the brakes were 'a bit scary', and you needed to be a bit of a Bernd Rosemeyer to cope with on-the-limit handling. I recall driving at 45degrees across a London cross junction because the tyre pressures were a bit low... buttock clenching stuff.

Tatra isn't one of the big players on the European truck market yet, but they are renowned for their very capable off road chassis. The use of air suspension on a dump truck is rather special, these usually have leaf springs. On European road trucks and trailers the use of air bellows is almost universal on all brands as it gives a smoother ride and therefore offers better comfort and minimizes cargo damage due to bad roads. Semi trailers have 3 independent air sprung axles with super single tyres rather than the leaf spring tandem axle still so common in the US.

[@NekorektniPochybovac-or8bi]

The stiffness of the chassis is not that much about comfort as about ability to withstand load in long-term. Tantras generally age much slower in harsh conditions. MAN or M-Zetros are very good trucks and sufficient for most of the duties. But when you're in mine, far north, desert, muddy forrest and such 24/7, you'll quickly realize the difference. And yes, I wanted that truck test & rallye driver in Tatra too, when I was younger :)

[@b101uk]

mmm, the Tatra method makes it much easer to mount body structures upon the chassis that are susceptible to torsion, conventional chassis need bodies designed with torsion in mind, and in the cases of bodies or loads that don't twist they need 3-point or other types of multi-point mounting that permit the chassis twist\torsion while allowing the body to remain ridged, when it comes to ridged bodies the Tatra is cheaper in engineering that body solution, BUT it comes at the compromise of off-road ability at extremes, while a body or mounting method which permits torsion with a conventional chassis will have greater off-road ability at extremes provided it is matched correctly with suitable suspension. the central torque-tube and thus enclosed drive-system is what makes Tatra ridged and arguably longer lasting in harsh conditions, but it is also what causes them to get stuck more often, have worse ramp-over angles, and take longer to fix when the do brake, relative to conventional drivelines. as for operation in the harshest most unforgiving conditions of heat or cold, mud etc you have to weigh the risk of breakage of items which is inevitable, with that of availability and ease of replacement of parts in a timely manner, and the ease of working around a situation of a breakage, and that is where for the small advantage of Tatra Mercedes, MAN, Scania, Volvo have Tatra beaten, as Mercedes for example there are very few country's on Earth that don't have some form of Mercedes dealer, given if you have an EPC (electronic parts catalogue) ANY Mercedes dealer even if they are just a car dealer you can order truck parts to be delivered there for your specific truck based on its VIN number, so you can just tell the dealer what you need without reliance on the dealer to find the correct part themselves. there are significantly more fleets Mercedes, MAN\VW, Scania, Volvo running very high payloads\train-weights in harsh mining conditions in South America, Africa and the middle-east and Asia than there are Tatra.

[@oakld]

@@b101uk As for the chassis, I haven't heard of anything that makes rigid chases less capable. Especially it doesn't make much sense in case of Tatra, which has half-axles that adapt to terrain much better than fixed axles. Axles of Tatra are not lower than fixed axles with same tyres. Even the central tube between axles doesn't make much difference, drivers drag it over logs or terrain bumps with no damage. With exposed drive rod (which is the case of most classic chassis), you have to be very careful and maintain safe clearance anyway, because it's super easy to snap it. Don't get me wrong - all those brands like MAN, Mercedes or Volvo do also great trucks and in most conditions they will work very well. Tatra is very heavy duty truck out of the box, even if you take the basic dumper truck. So even comparing them is from some point of view unfair. And this has also effect on reliability and need to get spare parts in the first place. Not to mention, that these days you can get Tatra spares anywhere in the world, even lot of chinese knock-offs, if you're advanterous. But yes, Tatra certainly doesn't have such a dealers network and AFAIK their main selling point is to convince customers to compare long-term wear and costs. I know for a fact, that some dealers do things like rent one truck to a stone mine long-term, so that cusomers can compare. And they succeed enough to grow, so it seem to work. But again, you'e quite right, that Tatra won't be a top choice in much of the world, because in developed world in most places you don't have difficult terrain and harsh conditions and you do have those MANs and MBs around the corner.

Tatra suspension is pretty unique. They run a central drive spine down a tube instead of propshafts. Then the axles are ran off that spine making every half axle totally independent.

The last test is the most telling when it comes to AWD, as the MAN did better IF you know what to look for, note the left side No2 axle wheel was off the ground on the Tatra which is lost traction and increased mass on the remaining contact wheels of No1 and No2 axle which would cause deeper wheel ruts relative to the MAN (deeper wheel ruts cause more resistance), but it is the rear bogie of No3 and No4 that is the fundamental advantage of the MAN, as the Tatra undergoes huge weight changes between the wheel that is highest on No3 axle and the wheel that is the lowest on No4 axle, which is a fundamental problem with independent none-reactive suspension off-road, while the MAN uses a two-spring balance beam bogie setup, which is a reactive suspension, meaning as say the left No3 wheel is forced upward the left No4 wheel is forced downward and the weight on the rear of the truck is presented on the left and right spring carrier trunnion, in essence the left and right spring function like an inverted seesaw, and the weight on the respective left and right No3 and No4 axle wheels is much more uniform through a greater range of undulation, which means shallower wheel-ruts, less resistance to moving forward, and better maintaining of traction.

[@CrazyBubaCZE]

[@b101uk]

@@CrazyBubaCZE but here is the thing, chassis rigidity is one of the enemies of off-road ability, and shifts the bias of capability onto the suspension side of things, it was the Tatra that had a wheel OFF THE GROUND due to the combination of rigidity and deficiency in the suspension, and the suspension especially with regard to the rear axles has further less obvious deficiency when it comes to how weight is distributed upon the wheels as suspension articulation changes. like any test for the purpose of marketing or other bias, you try to highlight the positives while ignoring the negatives, a wheel lifting OFF the ground is a negative relative to the MAN that didn't, as is one of the problems of independent none-reactive suspension on multi-axle setups on undulation like shown. nothing I said was nonsense, and was based on the ability to objectively look past what the "test" was presented as, yes the Tatra is more ridged if you want to only see that bias and want to ignore the other things seen or the fundamental problems of one system vs another.

[@fraserwright9482]

This is a Rock crawler 4x4 view. A truck is a tool to do a task. Having driven a T815 8x8 and a Scania R 8x8 the Tatra just works better. It has locking diffs on all 4 axles and you rarely need them in anything other than soft sand or mud. Add into this that your load is staying vertical which in a HGV truck is important as roll over is a risk that the Merc U5000 unimogs suffer from as the cab/bed are articulated so the loaded bed will pull the truck over as it weighs more than the cab that the front soaked up ok. If you are empty that is ok but that is not what a HGV is for is it? Also in terms of traction or speed in the Tatra that means momentum, you can maintain a static forward speed because all 4 axles act the same way and fully loaded this is key. If you think this is all BS then Google Truck offroading and the weapon of choice here is the air cooled V12 T813 8x8.

@@CrazyBubaCZE but I don't live in a 'theory world', I have empirical knowledge from years of driving off-road in 4x4, 6x6 and 8x8 trucks, some of which I have owned while also engineering bodies for them to convert them from their former life, this includes for forestry, another area I have spent many a years in in the past. you mention 'truck trial' tell me, when was the last time a Tatra won the European championship in the 6x6 or 8x8 class? that's correct they don't for as long as I can remember, its trucks like Ural, Zil, Steyr and MB in the 6x6 class and MB and MAN in the 8x8 class, which are for the most part trucks that use same functional rear bogie axle group suspension setup that maximises articulation and equalises weight distribution upon the wheels for longer like the MAN in the video, yes people do use Tatra mainly in the CZ rounds, and yes they may occasionally win the odd singular event or stages within event, but they are just not consistent or good enough to win the championship based on multiple events each with multiple stages. chassis rigidity\driver comfort dose not get your load from A to B per se, now maybe if you have to move some glassware or lose eggs from A to B that may be a factor, but for most things moved off-road its not, your main consideration is NOT making wheel ruts as deep and getting to point B, maintaining wheels on the ground for as long as posable thus having your weight distributed on as many points of contact as posable, while minimising the maximum weight placed on any individual wheel, things like 'driver comfort' are secondary or even tertiary considerations to the primary tasks of, crossing the terrain and getting your load there, and maintaining the pathway for as long as posable for subsequent passes, and when you have high individual wheel loads caused by chassis rigidity and deficiency in the chosen suspension type being none-reactive this dose not help reduce wheel-ruts or the longevity of the pathway for re-use and subsequent passage even though it may be more 'comfortable', given things get significantly less 'comfortable' when your truck IS the cause of wheel ruts getting deeper and your truck coming to a stop. after all if your the Tatra marketing department or test driver there are many ways to make your competitors truck look worse, like change the rates or dampers of the cab springs, wind-up the pre-set driver mass of the air-seat to make it much more ridged rather than floaty, run the tyres at significantly higher pressure than the axle-load would dictate to maintain SLR, pick a speed for the test that the harmonics of the corrugations of the surface are misaligned to the harmonics of the suspension of your competitors truck rather than your truck (for the uninitiated harmonic corrugations are why things like dirt and compacted gravel tracks that are traversed at moderate speed get a washboard effect on them and pot-holes at seemingly regular intervals, and why there is an individual incremental speed bands that a vehicle will ride at its smoothest, and small increase in speed can have a transformative effect in ride comfort, as the compression and rebound rates of the suspension dictate the distance between the peaks and troughs of the sinewave of the suspension vs the sinewave of the surface, and small speed changes change the relationship of how the sinewaves of both interact, the same applies to cobbled surface too being optimal speed-bands for smoothness based on the aforementioned). there is NO MAN fanboyism here from me, as what i talk about is a common suspension system used by most of the worlds truck makers for their high off-road bias trucks and heavy haulage trucks, because it offers the most articulation, maintains an equal weight on the rear drive-wheels through the greatest range of articulation, because it is a reactive-suspension, in the case of the video it just happens to be depicted on a MAN in this case, but can be found on the trucks of MOST manufactures from across the world. the only fanboyism in this thread is from the Tatra brigade....

[@ahorton6786]

Is it me ot does It look like the Tatra is going slower in the bumpy Road comparison?

[@ianmurphy9096]

Air suspension in trucks is usually terrible. If they go onto anything like loose materials, they either just stop driving forward or spin. Not sure why but out Civic Construction company trialed one and then gave it back. Also, yes they float on the road so while smooth, never stop bouncing or rocking from side to side.

[@Brazzelkanal]

The Tatra Suspension has a disadvantage on road because of camber change on wheel travel. It was good and unimportant on big diagonal offroad tyres, but with belted radials you loose grip and get an uneven tread wear. That's why the swing axle disappeared in the late 60s, it is also prone to roll over due to a high roll centre and resulting high roll momentum.

[@Stepica]

All you said is true, however in these big trucks weighing almost 20 tonnes empty, these issues arent as big of a problem as you might think. Normal cars with swing axle, that is a big oof, like tatra 613 or american corvair. But these big rigs benefit from the torsion stiffness and angular rigidity of the tubular chassis more, than they are disadvantaged by the camber change. Just my two cents.

[@pinzgauerbelgium]

The swing axle ( torq tube) design was used Ti'l 2000......the man who invented this was Hans Ledwinka , later his son Erich Ledwinka used this design in the Steyr-Puch-Haflinger and later in the steyr puch pinzgauer.....the last pinzgauers wher build in the u.k Til 2000.

[@Brazzelkanal]

@@Stepica Yeah, that's true, but still, road performance is lacking. And since even nearly all offroad hauling trucks in Central Europe drive most of the time on paved roads, it's quite important.

[@Brazzelkanal]

@joeri gielen the torque tube yes, the swing axle was patented by Edmund Rumpler

[@4t61405]

This misalignment of the axles disappeared after the air suspension of the axles, which keeps the axles firmly on the road, in itself as purely road vehicles they lose advantages, but on uneven terrain they have no competition

[@Iam-mad]

TATRA 💪💪

[@PropperNaughtyGeezer]

Tatra are now assembling with DAF. The independent suspension has always been ingenious on the Tatra. With steel springs, Tatra always had the problem of quickly hitting the ground in the middle when overloaded. The problem will probably not have the air suspension. Unfortunately, I haven't drive a Tatra myself. Of course, like any other air suspension, you can manually move the air suspension up and down, which further increases the off-road mobility. Really great. It's also the only truck who that has it.

[@haukesattler446]

Sadly the Tatra air suspension IS NOT like other trucks air suspensions. The ride height has major limitations. Due to the swing axles there is only one ride height with a neutral camber angle. If you pump the air ride higher or lower you get a positiv or negativ camber angle. Modern truck tires don't like high camber angles. That is why the classic Tatras had these rounded tires (like on a wheel barrow). Normal trucks with beam axles have fixed camber angle, Independent of the ride height.

[@bunter6]

I thought that cab looked like a DAF based one.

[@annaplojharova1400]

F.e. just the fact, that the MAN is significantly older and that the MAN had mechanic supension, while the Tatra has pneumatic(MAN has pneumatic suspension too) and, at least in some clips, it looks like there is a significant difference in speed betwen the Tatra and the MAN. I am German, so I tend to favor MAN over Tatra, but I'm happy to accept a fair comparison. This one just doesn't seem fair at all. Anyway, I love ya man.

This is supposed to make the Tatra look very good in comparsion, that's for sure.

Tatra even made limousines and luxury cars back in the 20th century, the most famous being the beautiful and highly sought-after Tatra 603 and more utilitary, but much faster 613, with the last personal cars produced by Tatra were the MTX Tatra V8 and Tatra 700 series with a limited run.

[@tronsl3014]

The question is why they make the test under different conditions…. I mean the Tatra drove over the bumps with 25 km/h and the MAN with 20 km/h or 6 to 10 km/h… it can be the case they hit with the MAN truck frequencies of the truck and with the Tatra not….. if you will drive with the Tatra over different bumps with different high, distance to each other and speed it can be look the same like the MAN. So there is the possibility with this setup they hit natural frequencies of the MAN but not of the Tatra… you can’t compare Tests with different parameters…. And still if they use the same parameters it could be the case you hit at one truck the natural frequencies more than at the other truck…. An active suspension is pretty cool that you have nearly no movement of the vehicles body or cabine while driving over bumps

[@fliteshare]

Tatra are build in the Chech Republic and they have the best offroad PATENTED chassis design in the market. Tatra came with a 12L V8 aircooled diesel engine. Which for enviromental reason were no longer allowed to be sold in the EU. Thus descided to switch to DAF MX13 engine/gearbox and DAF CF cabin.

[@samotnaf007]

ad 1 it is no longer pantented (patents expire after 20 years and there is nothing you can do about it) ad2 the aircooled V8 engine is still in use it complies with EURO 3 so the use is mainly for military, also V12 is also produced for military purposes ad 3 we din´t switch, the phoenix line (here in video) uses daf cabs and paccard engines, but we produce also line FORCE which can come with basically any engine you want 90% of the time is the cummins but if the customer wants volvo or basically any other engine is also a option.

[@dark_one1337]

did you know that the 4x2 or 4x4 configuration rides even worse since it didn't has the 2 more axles to carry the weight over for longer distance to keep it level or in line, the comany I work for has right now 7 MAN 4 axle Dumptrucks ,1 TGA, 2 TGS E5, 3 TGS E6 and the new one. the worst of all of them is the E5 Half pipe dump, semi Airbaged one with Coil spring cab ride, that thing rocks like the one seen here, on normal roads the TGA wich is the oldest with 41 ton full leaf is more comfy to drive than the younger mentioned, but yeah you can shoot over dirt roads like they were paved in a 4 axle you hardly feel the surface because of the compensation of the 4 axles. BTW. the new MAN even with leaf spring front and back as a 4 axle rides smoother than the regular 4x2/4 road version.

I think IVECO does them as well For long haulers its really a very tight market. Different trucks is best for different work. If you want long hual comfort, Mercedes is probably he one. I guess that is why they put the tatra to a Mercedes, because they have that reputation. If you want to haul 150ton and do it at a high speed, Volvo or Scania. If you want to pull 250 tons, and doing at at mostly low speed, then typically MAN is more popular.
