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.

Thank you! First video I could find that actually explains how these work

Impresionante!!! grandisimo video!!! gracias por compartirlo, esta tecnologia es la que debieran tener los 4x4 de hoy en dia

What a brilliant video, thanks so much for making it.

Great video. I saw these differentials on a dump truck in Russia. Finally, I get to see what's inside. Thanks.

Been looking around forever for a video that shows how that type of differential works.

Great engineering and great demonstration I would like to see how the the wheel hubs work as well

what a killer setup! i have to wonder what that rear diff section will hold power-wise.

Wow thanks for that amazing inside look much appreciated. Because of folks like you youtube is making geniuses

Amazing! Some respects to engineers and designers.

Great piece of work......thanks for being generous with the information.

really amazing, thanks for posting

Top notch quality video! Seriously. Thank you

What a great design!

sweet, thank you for posting this!

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

Pure genius design! Just wish I could afford one of them!

great video, the arrangement of the axles final dives shaft reminds me the tatra configuration

My grandfather helped to design it and he also test it in austria,in switzerland ,arabian and in many other countries.he wrote ab book about the history of puch his name is Dr Egon Rudolf

I always wondered what those diffs looked like. Now I know.

Thank you. Beats isometric drawings by a country mile. I am not a mechanic but it looks like a solid reliable system.

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

With this set up... Does that mean, there is a wheel further forward from the other side of the vehicle?... I think the right side wheel is always a few inches (cm) forward from the left side wheel?

😍 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.

Thank you very much!

Thanks for this explaining video.

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.

Tatra or Steyr? The right answer is LEDWINKA.

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?

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

Thanks again Guys !!!!

saludos desde Venezuela buen vídeo felicitaciones una pregunta espero me ayudes estoy trabajando en uno de esto arme una trasmicion delantera pero la monte y no acopla completa le falta x entrar como 1 ctm xq no entra

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.

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.

Wow, this just blew my mind

thanks you very much! that's i need !

awesome video man!!!

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..

блокировка мостов меж собой показана также делали на немецких магирусах только на одном мосту

THANKS A LOT!!

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.

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.

ขอบคุณมากครับ👍

ENGINERING MECHANICAL VERY GOOD INTELIGENCY

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

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.

That is pretty slick.

so when the diff is not locked, Is the one shaft driven and the other totally free balling? is there any friction drive or anything else putting torque on the outside coaxial shaft when the locker is not engaged?

Sir. Could you please elaborate on the 3 control levers on the dashboard. Also does this particular model have a centre diff- Transfer case. And in the 6x6 variant, is there a lockable inter axle diff. Between the 2 rear axles.

у татры полуоси не соосны? колеса потразному стоят?

I'm replacing some small sections in the rear cargo area side panels. Does anyone know the thickness of the body sheets? 1974 710m

awesome thanks!

where do i get one of these? i want to make a 6 wheel, 6x6 off road buggy with irs/ifs and one of these in the middle

Does that mean that the wheels from the left side are a bit offset from the wheels of the other side because of the axel placement to give room for the second crown and pinion set up?? So the wheels of the one side are a little behind the wheels of the other side??

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

Ingenious!

It doesn't matter where the design came from, these are awesome off road vehicles in 4x4 and 6x6 setup. The only downside is the complexity and hence the considerable in service maintenance required. Costs of major driveline failures are astronomic. Even the military wince at the operating costs.

so again. this type of chassis is from Hans Ledwinka, the first use of this chassis was the Tatras, is not talking about the video talking here about the chassis, as my colleague has already said that it was Tatra later is not true, tatra was the first in the video for the Steyr but chassis design is from Hans and was used for the Tatras and later modified in Steyr, Steyr chassis that could be used on bigger trucks because it interfered with the patent Tatras,Tatra heavy truck steyr light truck

В старых журналах За рулём есть фото рамы. Конструкции привода.

Thanks for explaining, amazing engineering. .but wouldn't want to work on that..very nice but would prefer unimog simplicity. .

So, it looks like one rear wheel is further forward than the other??

Any chance of a close-up look of the 6x6 system.

ive always wondered what would happen if the differential overextended itself and the two axle gears were to touch

Thanks that was good

bellissimo video guida come al solito sono sempre i stranieri a fare il meglio...

Качающиеся в корпусе редуктора полуоси интересно сделаны. Интересно какой у них ресурс, до того момента, как они потекут?

ท่านคะ ฉันมีความสุขมากกับวิดีโอนี้ และได้รับความช่วยเหลืออย่างมากจากวิดีโอนี้ และฉันรู้สึกขอบคุณมากสำหรับวิดีโอนี้ 🎉🎉🎉🎉

TATRA!!! Nothing else

💪💪

nice!!

Top👍👍👍👍

This is an origin TATRA concept...

So the wheels on one side of the vehicle are misaligned with the wheels on the other side! So the vehicle swerves as you brake hard. Crazy!

please what name of this differential, brand?

it was invented in Graz, Austria

Super! TATRA lässt grüßen. Gleiches Prinzip der Differentiale u. Pendelachsen.

Very powerful truck

to je snad vynález tatry ne ?

дифференциал какой-то нифуя непонятный,но сцуко мощный ! 👍

Wasn't this ingenious system created by Tatra?

neat.

на татре применено но калеса на татре по оси моста в разбежку

Where can I get the whole drive line of this product

Preferred system افضل نظام🌹♥👍

+++ thanks a lot +++

сальников сколько..замучаешься масло доливать

No RZR box

If you did use a Tatra Chachi, with a Scania V8 Diesel engine, a M.A.N Gearbox, and Tatra's own Diffenrentiale, and a Daf stiringhouse, then you will have the strongest and the best Truck in the world..

really smart people invented that.

ليش ماكو كاردن

I manufactur all gear like sipral beval etc

neeraj. mastee

patented by Tatra

next time when someone inserts a comment and do not respond that it is someone else's invention, when the truth is that it's just a modification of something already used long ago, I wrote that this is just Tatra Kopřivnice concept, invented by Hans Ledwinka and used it in her first time, do not deny your right it's Steyr I just wrote that it was the original concept Tatra

concept of the Tatra

Iz is TATRA concept!!!!!!!!!
