Tank Chats #96 | D3E1 Wheel-cum-Track Machine | The Tank Museum


if you do like these tank chats do
please subscribe to the tank museum’s YouTube channel now we’re going to look at the wheel
come track machine now it’s quite unusual for some reason the experts have
it down as an armored car in all the old publications it’s referred to as an
armored car except in the tank museum’s own publication when it suddenly becomes
a tank take your pick it runs on wheels and
tracks at least that’s the theory but it’s unusual in that the tracks are the
things that go up and down the wheels stay where they are which is why the you
look at the front wheels here the bracket that holds them is sort of
riveted to the front of the vehicle there’s a big leaf spring running
transversely and there are the wheels their sole releases say they solid
rubber they’re actually fitted with a type of tire known as the natural air
pressure tire and those triangular bits in it are the pockets that track the air
the idea is as you’re going along they provide the cushion then you normally
get from a pneumatic tire what actually happens is half the time they fill with
mud by that time then of course it’s just a solid rubber tyre but there you are that’s like what they did they do we’re better than pneumatic spats and
they also give a very harsh ride and that’s what this one is now the rear
wheels you can’t see so easily they’re set in a sort of recess in the back of
the vehicle they’re the driven wheels they’re fitted with the same sort of
tires and they’re all hidden by them mechanism that makes the tracks go up
and down and they will do it about 25 miles now in its wheels and probably
about 10 13 miles an hour on tracks that was all now the tracks you’ll see are on
a framework fitted to the side of the vehicle they move up and down on Rails
on the side of the vehicle and when you go up close and have a look at them they
don’t appear to have any sprung suspension at all they do move each
wheels on a sort of some bracket arrangement and I think they work rather
like the American light tanks the early ones they adjust
to the ground and they adjust to one another but they’re not really sprung
not in the proper sense so they give an even harsher ride on the odd occasions
when you used them the tracks are powered they work on a swingarm basis to
go up and down driven by the motor vehicle is powered by a 90 horsepower v8
Armstrong Siddeley it’s the air-cooled engine the same engine you find in the
medium tanks and that’s located here in the front with the driver alongside it
it’s a most peculiar system because that engine not only governs the movement of
the tracks going up and down it’s also and you can select these and I’ll lever
it has two other options one of them is to drive the wheels which it does
through the differential at the back the other thing is to drive the tracks which
it does from the tracks are on the ground and you have to select which one
you want each time on tracks the vehicle has an incredibly short track base
actually almost within the wheel say wheel layout of the thing and therefore
it must walk quite heavily but they didn’t seem to worry about that at least
if they did they didn’t know it was going to do it till they built it well
three of these altogether two of them were built by vickers-armstrong this is
the in 1928 this is the first one and it’s fitted with two turrets as you can
see the main turrets up there has a space for two machine guns were fitted
in they never were mounted it was only ever an experimental vehicle and there’s
another rotating turret on a lower level at the back with one machine gunner or
at least it should have and that means the vehicles complicated anyway but they
built another one which was more or less the same to look at except it didn’t
have the superstructure at all behind the drivers position was just a
big open tray we don’t know what it was intended for but one was built and
tested in the scrapped this one as you see has survived the third one was very
odd it was built without tracks at all solds an armored car to the Hungarian
police what they wanted it for Lord alone knows and it ran on solid tires it
must have been a swine to drive in normal circumstances but there we are
that’s what happened to the third one of these vehicles and you do see old photos
of in and again in hungarian service which is quite an unusual arrangement
but that’s the basic vehicle for you it’s covered in arm what it’s not really
armoured at the moment it’s mild steel but it represents Armour eight
millimeters thick which is the same thickness as your find on a rolls-royce
armoured car so although it’s quite it’s bulletproof up to a point it’s not
really very substantial and is easily knocked out by a tank but whether it
really was a tank or an armored car nobody knows it’s just one of those
oddities but really the whole wheel and track concept is idiotic it means that
you have got to select what you the conditions you want to the ground you’re
going over and you can either have a wheeled vehicle running at reasonably
high speed or a tracked vehicle running very slowly that’s usual with these
things but horrible thing to drive and even worse to attract chopper 8 in any
sense very uncomfortable other thing if you
like these films please do subscribe to the tank museum’s YouTube channel and if
you can please do support us on patreon

  1. Whale cum

  2. This video is on the right track for some joke cum pun

  3. I wanna cooooooooooooom

  4. Hehe cum..

  5. …And if you pull the secret lever, it turns into an Helicopter!

  6. At least it did not run on lugged steel wheels?

  7. I thought the idea of wheel and track was to run the vehicles on the wheels, when possible, to extend track life. An interesting concept but impractical.

  8. Hehehehe cum track

  9. Oh the inter-war Brits, gotta love em…

  10. Fletcher tells it like it is.

  11. The way I see it, since the wheels don't move from where they are affixed, and the tracks can be pivoted up and down for optional use, it is indeed an armored car.

  12. OMG, a new David Fletcher video!

  13. What an odd duck.

  14. Congratulations Tank Museum! I was looking at a Led Zeppelin video the other day, which had a very good feedback ratio, and I noticed the museum's feedback is even fresher. That's a compliment!

  15. Cum track

  16. Wheels and tracks I understand, but you cannot go to war into a machine that has "cum" in it's name

  17. excuse me? ze what?

  18. I'd love to see that thing running around the arena. I would think this device was designed for Colonial Policing and was never meant for use in a full-on war.

  19. Heheh…wheel-cum

  20. That comment about the tire filling in with mud 😂

  21. Why in the world would anyone give these videos a thumbs down? They are informative, entertaining, and FREE! Hell, I would tune in to listen to the Great Mustache read a phone book!!

  22. haha cum

  23. does the tank run on cum?

  24. Wheel-cum

  25. This thing looks like those toy tanks that came with the bags of plastic soldiers

  26. You know what this thing needs? Being amphibious, yes!

  27. What a wacky vehicle! Great presentation as ever!

  28. Optimus Prime calls it pappy.

  29. i would call it a half track

  30. (5:52) Strange: the clickable Patreon icon on the last of Fletcher's screens (up-left from center) shows a YouTube 'video deleted' icon. I wonder if that was intentional, a form of protest against YouTube.

  31. Ty Sir Fletcher as always!

  32. …..bless Fletch and his 'old man' trousers !

  33. The tracks are so narrow that they don't look like they'd be much use.

  34. So?? The Sovjet BT 5 and 7 could be fully driven by wheels by taken away the tracks.
    ..so whats your point? Senile?

    Btw, its about your age and also obsolete.

  35. It has always seemed odd to me that the original WWI tanks born of necessity were, given the development period, great engineering solutions but these inter-war machines seemed to go off in all sorts of odd directions. Where, and how did the War Office/Vickers think all of these strange machines were to be deployed – this one is hardly cavalry!
    The logic of tank development, standardisation, production techniques etc, seemed to escape the people responsible – can anyone explain why so much effort was wasted given the knowhow that must have been gained during WWI.

  36. Tank museum advert before a tank museum video, I’m not complaining, youtube knows me well!

  37. wheel cum?????

  38. Makes you proud to be British, doesn't it?

  39. Back in those days engineers had some bizarre ideas for armoured vehicles and most all things military. But by WWII some bizarre ideas were employed with great success………such as the Sherman with front flailing chains for detonating mines………and the Sherman with the front shear like bumper installed to tear through hedgerows. In war, necessity is truly the mother of invention.

  40. When a vehicle cant decide if its a car or halftrack

  41. I am at loss for explanations for why this thing exists. Best i can come up with is a group of vickers engineers having a really, really drunk night and crazy bets were launched.

  42. I don't care if the Brits scrapped it or the Hungarians bought it, I want that thing to drive downtown in Rome, put the tracks down and cross our giant potholes with class and style.

  43. Heh Heh… cum

  44. what a weird name for a reproductive organ

  45. At 5:30 he says that "the whole wheel and track concept is idiotic" but doesn't back that up – indeed what he goes on to say suggests that it could have been a pretty good idea. I'm not disputing his view – Lord, his little finger knows far more about this subject than I ever shall. But it would have been nice to know WHY he thinks the idea was idiotic.

  46. See the Sd.Kfz. 254 for another such oddity & it's from the 30's.

  47. Get to work Brono models!

  48. National treasure and I don't mean the vehicle

  49. Just found this on British pathe "Getting Ready For The Grand Manoeuvres (1925)" I did not know how far ahead the British Army was just after the first world war. This short film has in it med c at lest a squadron. Full tracked towed Artillery going like hell it lookes like the old horse artillery with 18pdr field guns. There is a playlist of 75 short films "Tanks Through Time" would love Mr Fletcher to put a sound track on this now that would be fun

  50. So goofy it might have been a G.I. JOE vehicle.

  51. I am beginning to believe that David hates all vehicles.

    Can we actually get a video of one he likes?

  52. ha ha wheel-CUM-track

  53. When you say 3 were made, do you mean 3 different variants or 3 of this type of vehicle?

  54. I see lots of confusion about if it is a tank or an armoured Car, the correct answers are
    – Yes
    – Both
    – You think Transformers are a late 20th Century Idea, oh boy, have I got news for you, not just the Brits, the Swedes, Czechs and Austrians all dabbled with this concept between the wars.

  55. He never says, but I'm quite sure it was deployed in defense of England against invasion in 1940.

  56. 👍👍👍🇦🇺🇦🇺🇦🇺

  57. I think the 2nd prototype with the open tray might have been an APC.

  58. I never knew this contraption existed until now. I wish I could go back.

  59. If Wargaming come up with the Hungarian tech tree this tank can be tier 1.

  60. Very ingenious idea! Wheels for fast movement on roads, tracks for cross-country mobility.
    I see it as a heavy armoured car with auxiliary tracks, rather than a tank with auxiliary wheels.
    With the tracks, it would be able to handle off-road terrain that would be impassable to an early 1920's armoured car – since they also had thin, solid rubber tyres, which would sink into soft ground and get bogged down.

    But the development of large, wide, low pressure pneumatic tyres, as seen on 1930's armoured cars, could handle soft terrain, and made this vehicle unnecessary.

    If you look at it from the perspective of the early 1920's, it's very impressive! But by the early 1930's, it's already completely obsolete.

  61. Strange design

  62. Thank you for all the tank info, it's really informative, I may be 16, but I love tanks and ww stuff.

  63. I must say, I absolutely love tank chats. The vehicles and history are sp interesting, and David is such a charming fellow to listen to. As a history buff, an ethnic Briton, and an engineer i find endless entertainment in these. Don't ever change.

  64. I'd love to see the inside of these tanks. Kinda like the Chieftain's Hatch series.

  65. It's the bloomen platapus of armoured vehicles it has a bill & webbed feet,spends most of its time in water but it's not a duck.

  66. >Wheel-cum-Track
    What an unfortunate name.

  67. Thank you for making these videos. For house bound veterans like myself, they are very informative and entertaining.
    Following the evolution of armour is a fascinating subject. So many first ideas turnout to be stupid yet, without them we would never have discovered what actually worked. It takes a war to properly kick start ingenuity.

  68. Perhaps the flatbed version was meant to be used as a logistic / resupply vehicle?

  69. Heheh… cum.

  70. Hey ! This isnt….never mind.

  71. Well, you can't accuse them of being afraid to try something different.

  72. I appreciate Davids Humor, good vid ya'll.

  73. Haha, cum

  74. Oh dear, somebody left a male tank in a field of armoured cars.

  75. Wouldn't it be classified as a halftrack?

  76. What a fantastic name good job people!

  77. And they said the soviets makes weird tanks, or a half track, or an armoured vehicle, I confuse

  78. The title of the video gave me anxiety.

  79. I can see why this didn't get past prototype.

  80. Makes me cum, wheel track.

  81. 2:06 It was originally going to take the same 6-pdr as the Medium Mk. C and D

  82. "a big open tray. we dont know what it was intended for."

    C'mon man, you have an MBE. Use your head. It's a Prototype Bren Carrier.

  83. The back wheels get mucked up too?

  84. Is he ok? He doesn't look as good as he used to.

  85. A very interesting vehicle, if a little bit Heath Robinson. I love the Tank Museum's treasures and rarities ( including David Fletcher ).

  86. This has many boxy & design aspects very similar to the early Japanese tanks experimental models and the Type 89 I-Go;
    ..with the front hull door(s), the rear decking air vents, the front glacis & rear decking hull angles, the general look of the cupola, the tracks sub chassis and the seemingly tall tapering turret.
    Those similarities could be mostly of a coincidence in design – due to usual human sizing & shapes, WW1 era industrial & manufacturing prcesses and infrastructure, military vehicle equipment requirements, the engine & drive-train etc. Plus perhaps with some indirect basis of shared industrial know-how from the times of the Anglo-Japanese Alliance, which Vickers was quite 'heavily' invloved with before it was dissolved in the 1930s/or 1931?

  87. Disappointed there wasn’t also an attempt to make it amphibious!

  88. I was keeping the notification with the previous title just for gigs

  89. Something like this, but modernised a bit, would be useful to traverse the huge unrepaired pot-holes on suburban roads today.

  90. So when is wargaming putting this in the game as a premium tank?

  91. I AM subscribed since you make those videos. 😏

  92. And there is the wheels… there and uh……….. 😂😂😂

  93. Tankette: I'm home alone.😘

    D3E1: I wheel cum right away!

  94. Well, I searched for more info on the “wheel-cum-track machine” on line. At work. Is anyone hiring?

  95. Came for the cum, stayed for the wheel-track

  96. Always enjoyable and insightful.
    Thanks for sharing.
    G.

  97. Now we know why there is a convex worn dent in that old design table from Vickers.
    They banged their heads on that table so often they could think this up.

    The rumour goes that since then, every design table at Vickers was heavely rubber lined to prevent braindamage.

  98. What an odd looking machine! Can only have been experimental.

  99. Coming soon to WoT!!! As a premium of course.

  100. i swear that if you went to the vickers meeting for this "vehicle" you'd have that one guy who disagrees with everything and so everyone else added the wheels to shut him up
