I am a BMW tech and I drove a 710m for many years. I never knew what the heck was happening in that driveline so thank you so much for making that.

the most capable offroad driveline humanbeings ever made! Salute Ledwinka!

Haflingers and Pinzgauers are designs by Erich Ledvinka son of Hans Ledvinka constructor who worked both in Tatra and Steyr and design vehicles with tubular (backbone) frames with propeller shafts inside of them. So we can talk that construction was inherited rather than copied.

By far the best and shortest video explaining how something works, only facts. Thumbs up.

That's an engineering masterpiece.

😍 I love Tatra whole my life and knew nothing about Pinzgauer. Thank you for this video where you can see how Pinzgauer and TATRA work, but at the same time I started to wonder why Steyr can use the same invention as TATRA and I learned a lot of interesting new information about the life of Hans Ledwink. This technical genius was during a gala evening on March 6, 2007 at the Geneva Motor Show, Hans Ledwinka inducted into the "Hall of Fame" among the most important designers in European car history. In 1961 he was awarded the Rudolf Diesel Medal.

Tatra or Steyr? The right answer is LEDWINKA.

They are sure design not to fail, a lot of strength design into it

Great video! But how about sealing on axle housing.? That rubber is enough?

awesome. ifs/irs with portals! how strong are they comparatively to solid axles with portals?

Thanks for this explaining video.

Thanks, I really appreciated that explanation. Simple machine ideals whipped into a fantastic package. Does this utilize portal axles at the outside for better clearance? How does this compare to the driveline in the Haflinger?

Yes, there are drop gearboxes at the hubs, making them portal axles. Haflinger uses a similar backbone layout, but with conventional differentials and axle joints (and the engine is placed differently).

Does the Tatra system work like this as well? Absolutely brilliant way to design an offroad vehicle and an excellent explanation of how it works as well. Thanks.

Ledwinka was the only man in the world, who was able to design design this conception for mass production. And because Ledwinka designed Pinzgauer as a freelancer, Steyr didn't hold the necessary know-how to design other vehicles with this conception. The cost of development is the only reason why Tatra is the only producer of vehicles based on this conception.

awesome video man!!!

Thank you for this amazing Video! I came to it while studying Tatra Trucks, but the title here says "Pinzgauer." Are they related? Do, or did, Tatra Trucks use the same axle manufacture as Pinzgauer? My research, so far, shows me that Pinzgauer and Tatra are a line of Trucks, and not necessarily the drivelines manufacture. A second question, in my head, after watching this video, is to learn more on just how the independent axle travel was limited. When either the Truck leaves the ground (Think Dakar Rally), or by bottoming out, say when the Truck is overloaded on rough terrain. I did hear that pins of some sort, in the upper axle house facilitated the limit, but I would sure love to see how that is being done. Also, I will try to go and look now, to see if I can find the History of this "Pinzgauer" drive system, in the Dakar Rally.

Tatra builds it's own drive line and there's plenty videos on KZread showing this. Hans Ladwinka designed this system when at Tatra in the 1920's and his son did a similar design for Steyr-Puch (who make Pnzgauer) in the 1960's. So the link between the companies is father and son and nothing else. Tatra build their own vehicles including the driveline and Steyr-Puch built theirs although BAE Systems Inc. bought the rights to Pinzgauer in 2000 and built them in England from then onwards.

Captain Win - Thank you very much for those pieces to the puzzle! Now that makes perfect sense. I have seen some "Tatra built" wording in several videos here, but no "Tatra building" these drive lines. I will narrow my searching a bit more, and do my best to come up with some of those. Most people don't know, or dig in deep enough to find the differences. Licensing deals could be playing a role, behind the scenes for example, in some manufacturing/assembly lines, and we wouldn't know it, until we look for those answers. I am wanting to know the entire history. Again, thank you very much for taking the time to reply with that information.

The son Erich Ledwinka also worked some time for Tatra and took the concept to SDP. They even got sued for it. You will also like the Haflinger which is built the same way but smaller.

Backbone tube nicely explained. It is interesting to compare both Porsche and Ledwinka continuing to develop same ideas as Tatra on other side of Iron curtain. Pinzgauer reminds me mostly of Tatra 805. They both look a bit nervous off-road, perhaps because of high center of gravity. Despite that, both are quite capable.

ENGINERING MECHANICAL VERY GOOD INTELIGENCY

Aren't you moving the driveshaft in the wrong direction? The engine would move the shaft clockwise, looking from the front, which would turn the half-shafts what would appear to be in reverse, but because the Pinz has portal axles, the direction would be reversed by the larger bull gear in the bottom of the portal axle, providing forward motion. Correct? Otherwise, good vid.

Is there any adjustments for off- centered crown wheel of front axle differential? There is an hard pressed bearing sound in slow vehicle movements, noticable from drivers cabin. The sound vanishes once the vehicle pick ups speed above 40- 50 km/hr. We are rechecked and done all lubrication procedures for wheel , axle and steering. On removal of rubber protective oil cover from both sides of differential and checking crown wheel movement, it is noticed the slightly off-centered movement of the wheel in respect of the scraper plate. The clearance is more than 3mm at some point and vary to 0 mm clearance at some other point on right hand side. Slight off centered movement also exist in left side also. ( To clarify doubt we checked with another vehicle of same model and and found perfect rotation of the crown wheel). We are facing this issue with Tatra 815 6x6 euro 3 right hand drive vehicle. Can u please guide to resolve the issue..

Never seen one in person, would like to see one do its thing off-road

thanks you very much! that's i need !

Thanks again Guys !!!!

Very interesting way to arrange a differential, especially because it means the wheels on the same 'axle' are not the same distance along the vehicle. What can't be seen here is that (As far as I can work out anyway) the input drive to the diff turns the shaft that the side pinions in the meshed set of 4 in the centre of the diff are attached to. This transfers drive to the front at back pinions in the meshed set of 4 to transfer drive to the half shafts going to the left and right wheels. The locking mechanism locks the input shaft (Which passes uninterrupted through the differential) to the rear pinion driving the crown wheel to the left half shaft. Looking at the way the drive shaft passes straight through the differential, I suspect this is why they're able to make 6x6 or 8x8 versions easily with the same building blocks. The downside is that wind-up in the shafts will be an issue where there's full traction on all wheels as all axles will be driven at the same speed, so maybe there's more to it, my knowledge of this driveline is limited to guesses from looking at the video here only.

That is pretty slick.

Fascinating! I have read that the driveshafts are staggered by 30mm, due to the dual crownwheel setup. How does this translate on the ground? Are the portals slightly angled to compensate? I doubt that the wheels are staggered on the ground, as it would make the vehicle very near undrivable. Just in case you are wondering what the proper term is for "the witches hat", it is actually called the axle journal neck.

The torque goes through the main shaft to the boxy thing visible in 2:22, which distributes it via the spider gears to both ring gears, so also unlocked both wheels are driven.

One lever to engage drive to the front; the other two levers lock the front and rear differentials. No, there is no centre differential: it is a part-time system, in either rear-only drive or four wheel drive with front and rear speeds locked. No, the 6X6 has no interaxle-differential, or inter-axle disconnect: both rear axles are always driven, and always at the same speed. It's not good for paved surfaces.

In fact Hans Ledwinka designed the Tatra beautiful transmission and his son Erich designed the Pinzgauer transmission...
