How Mono vs Twin Tube Shock Absorbers Work

[happyrecluse]

Bare in mind, the shock is used to dampen the oscillating effect of the springs...

[nickstevens]

Pros and cons of each? The twin tube provides for a longer piston stroke. A single tube can get around this with a piggy back reservoir. Most cars have twin tube shocks but motorcycles habe single tubes.

on the monotube. you could always add a schrader valve and add or subtract nitrogen. drill out the other side and change the weight value to your liking. weld up the hole.

Thanks, my head was hurting trying to understand what the hell the gas is doing in the monotube. I finally know!

This 1 real time video demo is equal to 1000s of other videos showing in animation or explanation but still making viewer wonder how !

This is a great tool for visualization, still trying to decide which is better. Many people say that mono tube is better, but most affordable adjustable shocks are twin tube. Does it even matter?

You're saying fluid passes through a valve between chambers. What resets that fluid (pushes it back) to the original chamber? Is the chamber the fluid goes into under pressure..? What does does the 'work' to return it to the neutral state. Without a restoring force it'd consume all the travel. Yet, we've all seen that shocks "reset" (nearly immediately) without being installed, (eg, without the aid of springs). More importantly, the normal behavior of shocks is far too fast to be based off _fluid passing between chambers, _ and seems more consistent with a fluid compression.

It's not that I reject the explanation (of fluid moving between chambers) ... I'm sure I'm just missing some info which makes it make sense and consistent with what I've seen.

The main thing to note
Is that one Cavitates where the other doesn’t, and that’s where the true performance happens. Perhaps this would be helpful to explain.

Thanks, I was confused why there's an oil on shock absorbers when oil isn't that compressible

[BSBMFG]

Thanks for doing this video, I would like to also build a clear shock for teaching purpose but need help in finding tube and process for machining it. Can you help please

[SteveXNYC]

Pretty sure the air will mix with the oil when the fluid and material get hot from rapid action. If the rod seal leak, air will leak into the oil and thats the end of the shocks.

Beautiful beautiful beautiful explanation sir, I want to know if only mono tube shocks are filled with nitrogen or can twin tubes also be filled with nitrogen. My second question is I have a Toyota Etios whose front shocks dont dampen as good as they are supposed to do, experts say that grade 32 ISO is not suitable for front shocks in Indian driving and climatic conditions but it's okay for rear shocks. They advised me to go for 46 grade ISO oil for my front shock rebuild, what is your suggestion sir.

Good morning, I am an automotive training teacher. Where can I buy this demo kit? I am from Brazil

[sanagebo]

Hi thank you for the explanation
May I ask in mono-tube what is the pressure in the gas chamber?

[jwhquzv]

What type of oil is used in the dampers ??
is there any specific name for the oil or properties ?

[MasHaiHil]

What if I add air inside the monotube oil chamber? Will it make my ride smoother? Because my motorcycle monotube shock absorber are so stiff I think

[dabok]

my Q is... what happens if twintube test in up side position.. will it function properly?

[saultube]

You forgot to mention that some Twin Tube Shocks have also Nitrogen Gas, just like the Monotube Shock

[traka]

hello. How could I find out how far away I should leave the separator piston of a monotube shock and at what pressure I should pressurize it?

[brianfalzon]

Is the twin tube also charged with nitrogen?
