Heck yeah bro, the device worked well, and Garage 54 did a great demo of how cars absorb bumps and stuff. It would be even more friggin' epic if they broke the glass piston itself. :) Imagine the oil spewing out out at 90 psi (6 bar) or whatever the air or oil pressure is. I'm a man, we like when stuff fails*, as long as it isn't our own. That would add to the "shock" value, pun intended. *Disclaimer: Only in televised series or YT videos.
The air gap solution is basically like the spheres in Citroen hydraulic suspension (or the British Leyland Hydragas suspension), but there's an experiment for you, DIY hydraulic suspension, whether like the Citroen hydraulic system where you can raise and lower the car, or BL's Hydragas "set & forget" setup, retrofitting them to something that lives its' life on coil or leafsprings would be a fun test to see the difference... :P
@@Cheeky-Biscuit They probably could have, but as with all things experimental, it was never going to be a perfect design, plus they were trying to keep the oil as air free as possible so that it looked good on camera being all clear, thus separating the two sections... :)
@@Cheeky-Biscuit The rod changes the volume inside the main cylinder so that wouldn't work. Their solution is how some normal shocks work. Cheaper shocks will sometimes just allow an air pocket within the shock. Expensive shocks have an extra little reservoir to contain the pressurized gas.
Very cool. The shaft displacing oil is an aspect I wouldn't have considered. Now I know why the small diaphragm was necessary in the RC car shocks we built back when I was younger. And also I understand why more air pressure stiffens the forks on a dirt bike. I couldn't understand it before, since the air isn't acting on the shock piston with a bypass hole in it. The air disapating in the oil is cavitation.
Dirt bikes have air springs which indeed are acting on the stanchions. This is not the same setup, the springs on this car you can see behind the shock. EDIT: i am an idiot motorcycles dont usually use airsprings.
@@Christophe_L no. They have coil springs in the front forks. The increase in pressure is reducing cavitation to stifen damping. It doesn't raise ride height like Increasing spring rate would.
@@jasonbirch1182 While a lot of road bikes have coil springs, most dirt bikes have airsprung forks. But it could be the case that your bike in particular had a coil fork in which case I fucked up :) EDIT: nope, motorcycles dont usually use airsprings.
@@Christophe_L I'm not aware of any air sprung forks. The newest set I have is off a 200(?) yzf426 so maybe some newer bikes are, but I don't think that you are correct. Edit. After doing some quick research, you are not correct. There are some air sprung forks available but not factory stuff. It's experimental high end race motorcross damper builders trying air. They aren't practical for many reasons. Leaks, condensation from refilling with moist air. Heat rapidly affecting pressure. Non linear spring rate as compression increases. Springs are great. They just are a little heavy. So they keep trying to make air work.
@@jasonbirch1182 You are indeed correct and I apologise and self-flagelate profusely. I will edit my comments to reflect this. I was going by my MTB knowledge (where air forks have become more prevalent than coilsprung ones), and knowledge passed on from not very trustworthy sources plus lazy googling. I apologise again!!
You guys are the greatest it gives people with no mechanical background an insight to how these things work. Its also fantastic experience for the young mechanics ,they are terrific. Keep up the good work and warmest greatings to you all from Melbourne Australia.
But they have just did a gas spring. Real shock has some valves in the piston, oil is pumped via orifice (there is your source of heating). And almost 100% fill is a mistake.
Another great interesting show! Thanks for the view of a shock's working innards. An extra seal silicon-ed in at the top would get rid of that air pocket.!
Very interresting!. I thought the floating piston would have had more stroke tho!. What you did is a "De-Carbon" shock principle. They inflate the secondary chamber with Nitrogen tho, to keep the pressure more stable with temperature. The air that mysteriously appears is in fact Cavitation. It is BAD for a steady dampening action.
It would be interesting to see all the shock's like that one and test it with speed and hard cornering and braking to see if it's better than conventional shocks.👍💚💛❤️
As someone who builds aftermarket shocks for a living, I appreciate this video so much 😂😂😂❤❤❤ Edit: @7:30 the term for that is "cavitation" and can happen even when no air is present. When the air rushes through the piston, it created areas of extremely low pressure along the trailing edge of the holes. It's such low pressure that it makes the fluid turn to it's gas form.
I think this was all done just because Vlad didn't understand how shocks work, so now we all have a much better understanding of shocks thanks to Vlad's curiosity, Thanks Vlad!👍
Try putting a heavy spring in the compensation chamber instead of charging it with air. Not sure if you guys have a rack-and-pinion steering unit, but that would be really neat to see transparent.
Excellent work. I am very impressed. I would love to see four of those on a lifted offroad vehicle. Now that I have seen such good results I am sure this type of setup could work on a rock crawler type of vehicle. A high speed offroad vehicle such as one that might be used in the Paris Dakar rally might be too much but the cool factor would be out of this world. Great job fellas 😎👍
Gedday from AUS. You should put Car, Motall the transpaent suff together. Over time make a car, motor block and all the rest. Make a Gaage54 transparent and"OTHER" vehicle! Cheers.
hahahaha glass shock absorber that is great. im surprised it didnt blow up, but im sure you were hoping that it wouldnt the whole time you were driving it!
You guys should try to set an official Guinness World Record utilizing all your transparent modifications on one car? For the most transparent Classic Car Built
Hi. Panther bodies are very rare in Russia. There are some, but you definitely don't see them every day. I know Moscow police used a few all the way until the mid 2000's (I remember seeing them around when I was in college), can't remember when they were retired.
@@hairycat6095 I actually like the look of late 90's early 2000's Crown Vics (I have a thing for sort of "bland" looking sedans, in fact all of my cars, except for my old 5-gen Honda Prelude, have been sedans, three of them, including my current car, were American made). But when it comes to the Russian buying public, they mostly prefer Japanese, Korean and German passenger cars (though there are a lot of American SUV's driving around like Tahoes and Escalades).
Now I have my Poljot 3133 "manliest of man's watches" on my wrist, I needs a manly Lada to finish the cool dude look hehe Oh well I will have to just live with my iconic MK2 Reliant Robin just like the one on Top Gear :P
a small light could have been installed on the other side of camera to show off the action in the transparent shox similar to the light that was shown in garage
This is exactly how an IFP (internal floating piston) shock works except that there are flexible washers/ shims in the main piston that also control oil flow for compression and rebound. The fluid cavitation doesn’t allow the shock to dampen as well so nitrogen pressure is added to the IFP chamber and the result is very well portrayed in this video. Excellent job and video!
Can some explain why he can not push down the rod at the very beginning .He told because the rod is entering the tube and reducing its internal volume .But the tube volume seems doesn’t change . Is that something i miss? 🙏 BTW good video👍🏻
Dang they sound really good. But like many, taken too soon, Randy Rhoads, SRV, Cliff Burton, Bonzo. The list goes on, killer band. Seriously some of the best riffage, soloing, and songs ever made.
so why you dont use air shock, no bubbling, air does not need to be sealed in tightly, it can be leaky, both ways. try a air shock section airless wheel, where the air can be squeezed out and back in, around the rolling cycle, just like a leaky air shock.
the foaming you can observe in short instances while the shock is compressing is not air. It is vacuum bubbles cavetating. Explanation: While compressing at higher speed the orifice in the plunger makes so much resistance that instead of keeping up the flowrate for the movement, the air camber is compressed. While this happens the increase of volume in the upper chamber is more then the volume of the oil entering, developing a strong vacuum. The missing volume is filled up with vacuum bubbles, and the disappear they instance the vacuum disappears.
Yes. I'm sure you know, but let me utter a response here, for others to see: The flowrate that's enough to reach vacuum in that improvised piston design is relatively low, because they didn't include shim stacks. In a fixed size hole, the dependency of pressure on flow rate, is a square (if not some uglier power). It's not linear. In order to make their design work without the complexity of shim stacks, they = the authors of this educational prank, needed to make the piston holes relatively small, to get some damping effect during moderate piston movement speed range. Thus, they got spanked by the square, at flow rates that in fact were not so very high. The dynamic resistance got so high that it pulled pure vacuum behind the piston, even against the counter-pressure from the "compensation bubble behind the floating piston". With shim stacks, you make the holes in the piston larger, and at low flow rates, the shims add more resistance. At higher flow rates, the degressive shim stacks open more, thus alleviating the "square" in a fixed-size hole / emulating a "synthetic piston hole with a variable cross-section". The shim stacks thus "linearize" the pressure vs. flow rate. Calculating and making the shim stacks, or repurposing some salvaged ones, would be complicated, and would muddy up the visual clarity of the basic principles in this demo-prank. So they just skipped the shim stacks. Thus only adding to educational value of this vid, IMO. If they had shim stacks in place, we wouldn't be able to enjoy the beautiful vaccum foaming effect.
Easiest way to purge the fluid from the shock was to put a bleeder such as a zerk fitting (grease fitting) onto the shock. Would have released the air as well as the extra fluid.
I always love watching these!!! So interesting the things that are thought up, and then you get to see it in action, that’s really cool love these!!!! Thank you for the time and info!!!
I think, with ALL the experiments you've done with the old Lada cars, you guys COULD make a kind of Lada RS Quattro, so to speak... ONE HELL of a FAST, NIMBLE WELL HANDLING resto mod Lada. ie, fully rebuilt, blue printed, ported polished, turbo (maybe even Supercharged) Lada motor, uprated clutch, upgraded suspension all round (multilink independent front and rear suspension), maybe even a 4WD, then upgrade the interior too?... 🤔😏😉👌 😎🇬🇧
@@irgant just checked it out.. Are you talking about the brown Lada they cut in half to make it a 2 door? If so, you're way off! I'm talking a PROPER tuned 4 door Lada as per my description. Using a full on tuned (Rebuilt, Balanced, Ported/Polished, Blueprinted etc with new (forged if poss) pistons, rods, bearings) LADA MOTOR, with a FULL on modern suspension setup (hence multilink front AND rear) and ALL the mod cons like adding a Turbo or Supercharger and possibly 4 wheel drive and lightweight (maybe Carbon?) wheels. THAT'S what I meant... ie, the VERY BEST and BEST performing/handling that a 'Traditional' Lada could be... 👍😏
