An alternate method for determining armor thickness is to wait for a senior NCO to be sitting inside the vehicle, then using a hammer to hit the section of armor you are trying to measure. The actual measurement is determined by how long it takes for the angry non-com to pop out of the vehicle and start screaming at you. Naturally, the calibration is affected by a number of factors, including the NCO's general level of cafeination, time of day, what the nonsense lieutenant has been up to lately, whether a junior enlisted received a DUI the night before, and perhaps most importantly, the non-commissioned officer's "base hate level."

Very well researched, thank you. Another peculiarity of this tank is the restricted width, which is only 3 meters, due to the insistence of an important parliamentarian of the then tank committee on the vehicle being able to use tertiary roads. This caused many problems later in the Pz 68, the tank being very cramped and having no development capability.

At around 4 minutes when the Chieftan mentions the tracks were made of cast manganese, which didn’t make sense to me as you can see corrosion on the track links consistent with steel or iron. I’ve heard him before mention the composition of tracks before as manganese and say he didn’t know what it meant so I did a google search on cast manganese. It turns out the tracks are made of a steel alloy containing around 13% manganese called mangalloy or Hadfield steel which has priorities that makes it an ideal material for making tracks out of. Funny the rabbit holes you go into when you hear a weird piece of information in a video. 🙂

Very great video, Nick.

Nick getting tongue there a bit with his Pz 51's and stuff, but its not easy to do. the suspension is to keep the narrow profile. torsion bars can do this but have their own problems and are more hastle than their worth, Horstman types are good as they take up no internal space but you end up with a wider vehicle, this allows a best of both option with no internal space taken up but narrower profile to keep the doctrine of using Swiss tunnels. one final note is the armour should have a air pocket at the back end with diesel fuel cells in it, as they offer additional protection from SC attacks, this will effect ur ultrasound.

Track tension adjustment is automatic by means of a hydraulic system. Nothing needs to be done (nor undone :-) ). The suspension made for a very comfortable ride. You can easily figure out the full travel by the position of the end stops. The only problem was that you could shear off the bolts securing the suspension of the first road wheel to the hull, thereby loosing said wheel along with its suspension, if you hit a large solid obstacle at high speed. While the automatic tensioner kept the track firm on the tank and the loss of one wheel had no immediate impact on the mobility of the tank, it meant you had to go pick up the heavy piece of shit while your mates were chasing the birds in town, extract the remainders of the bolts from the hull and put the assembly back up. The ammunition port in the turret is not an ammunition port, it’s a case eject port. It is part of the casting and was there from the very beginning. It wasn’t present in the very similar looking predecessor, the Panzer 58, of which I don’t think there exist any outside the Swiss Panzermuseum. There is an ammunition port too, you can see it on the left side in the hull, just above the suspension of the third road wheel. The bowden-ish linkages connect the steering wheel, shiftlevers and pedals with the transmission, where all the shifting and steering happens. The common language of the Swiss military is swiss, german, french and italian.

Tannkkkksss.. we get tanks again

I know I'm really late, but I think I can add my own two cents to the Belleville washer rarity. I was looking into the system in modern use and the basic problem is, from what I understand, is that it's a high friction system--each washer has a high surface area of contact both with the other washers and its retaining material, whether it be a containing cylinder or a shaft. Any amount of dust or abrasive, ie from the washers wearing, quickly wears down washers, and you can't just replace them or you'll get early failures of the replacement; you need to get rid of all the dust. This isn't a problem in machine or civilian use because these systems do not need to be airtight like tanks need to for NBC protection. The advantages then are just the compact nature, easy tuning, and cheap maintenance as far as normal life is concerned--it's just a few rings of metal. So, it's a high maintenance system in an area of the tank that is hard to get to in the field, in the military where crew maintenance is not always the highest priority. Leftover material causing early failure is also a problem of torsion bars or so you've said, but it's a lot easier to pull out fragments than trying to clear dust out of a tank suspension. On the tank itself: the fit and finish is lovely! At least physically, everything looks to be well crafted, at least if we exclude the infamous electrical problems.

@magni5648

2 жыл бұрын

That makes little sense as far as I understand the whole system. The bellevile washers are in essentially tubes bolted to the side of the hull. Wether they're airtight or not doesn't impact the interior of the tank being airtight or not, the whole system is situated outside the hull. This also makes the suspension actually pretty easy to maintain or repair in the field if they're designed with an eye towards it: Pull the roadwheel pair, unbolt the unit for that roadwheel pair, bolt a new one into its place and put the roadwheels back on. Apparrently the only notable problem with the system the Swiss experienced was that if the tank hit a solid object at significant speed, it could shear off the bolts securing the front-most unit, causing it and the roadwheel pair to fly off. This didn't immediately immobilsie the tank, but was a bit of a hassle to fix, especially in regard to getting the remaisn of the shorn-off bolts out of the side of the tank.

@jarmokankaanpaa6528

2 жыл бұрын

The high contact area applies only if the washers are piled in the same direction, i.e., convex to concave. If they are piled in series (alternately back-to-back and front-to-front) they are only in contact at the centres or the edges and the surface-to-surface movement is minimal: two concave surfaced pushing against each other expand ideally at the same rate. I've shot old 152mm Canet coastal guns with Belleville springs in the return mechanism. Admittedly the stack was quite a bit longer than in the tank springs, but the 7.5 tons of barrel and breech recoiled back and forth around a foot and a half in a split second, so the springs were very efficient indeed. The springs were not encased, but then rust was more of a problem in the coastal environment than dust.

They angle the back slightly down to make it easier to sleep without a pillow because the bustle basket was too small to store pillows too.

You made me look up belville washer...... Fucker! Love you fellow tanker! I love how "gentle" you are with the tank....

I love neutral countries design (Switzerland, Sweden etc.) for the cool features that fighting powers couldn't afford at the time (both ww2 and cold war). They also may have these excessive design / naive unique features.

My wife is from Switzerland and speaks German, French, Swiss, a little Italian and now English. Depending on where you live in Switzerland, the main language spoken will vary between German, French, Italian, the Swiss dialect of German and in a remote canton where her mother came from speak a form of Latin, known as Romish, I think that's how its spelled.

It's spelled Romansh. And there are multiple Swiss German dialects. Almost 1 per canton.

@@lucariolps277 yes I am well aware of that.

You know what was weird to me? Hearing "CES" be called something other than "CES". (I'm referring to the "BII", aka the tools and other bits/pieces in the side bins)

What kind of monster can dislike a video such as this one?

Automobiles should and I hope will be like this one day; with a power-pak assembly with quick-disconnects.

Most cars now are built by putting the engine on the frame/chassis before the body panels as added. I have no idea how you get the engine put of a modern car. It was pretty easy in by 1973 Dodge, you could hoist the engine transmission assembly out with relative ease.

How am I just learning about this tank? I never knew it was even a thing

Because Switzerland is not a famous tank building nation. Same with Sweden. People think that these countries since they are neutral, don't make tanks.

aaaa, an actual honest tank, thanks chieftain!

That's the second time I've seen him step on the towing pintle. Of these days it's going to spin and the result won't be pleasant, and it surely won't be "easy enough."

M60 was Patton, not Pershing.
