Cybertruck Engineering Innovations - Great Summary

[CyberGus]

Have fun trying to find the rest of the exoskeleton... or stressed skin tube, because their ain't one bud!!

The entire chassis and passenger compartment (including the glass) is part of the exoskeleton

Boys, put 'em away and zip up.

The word "exoskeleton" in this context is a marketing term, not an engineering one. It's either all an exoskeleton or none of it is.

Don't make me pull this thread over

I found it interesting how they bend the SS panels. In an interview Tesla said the panel is laid over an air hockey type of production machinery. I would love to see the process in action.

Yall remember when jbee said the SS panels attached to the castings by "three little tabs"

lol. GG

Specificly to the cabin with those tabs, not the cast.

We still haven't seen the backside of the rear fender and how it connects. I've been frantically looking. Feel free to post something.

There's also a sheet on the rear SS skin to attach it, and it also attached to the inside bed wall.

I have a few threads of discussion where I've said what parts are actually "exo".

The rear fender is the only one I said it might have some "meaningful" ss skin contribution to torsional stiffness. Which btw is not the same as payload carrying, as this only occurs at full wheel articulation.

Yeah, I know, when you started to walk back your original claims a few weeks before release is when I realized you would never admit to being wrong.

But for me, this isn't about being right or wrong, it's about reality. The term "exoskeleton" is perfectly appropriate here. End of story.

There's an inner black bracket that's adhered to the skin They cover nearly the entire surface of the panel. You can see it in all the factory tour videos where there's a bunch of rear panels hanging.

You can see it in the crash vehicle where the plastic covering has popped off. They match the indentations of the castings.

That's what transfers force between the panels and the castings.

I'll pull out some stuff from way back on the forum, when I have some time. You'll see it hasn't changed much, if at all.

Pictures pls.

I'm not scrubbing through those videos to screen cap. You're free to though.

I've watched about 4 hour long factory tours and haven't seen it yet. So at least the right video would help.

Yup. That was how we were supposed to know it couldn't be structural.

Yes, it's a marketing term, but it's also a descriptor of how it's engineered.

"All season radial" is also a marketing term, and a very useful one because it describes not only how the tire is intended to be used, but also how it's engineered. Of course, "all-season" is not entirely accurate as most of them are not that good during icy weather.

"Full metal Jacket" is also a marketing term that describes the construction of a bullet. Of course, no one takes exception to the term simply because the "jacket" is not a "true" jacket because there are no holes for the neck and arms, and the "full" is not "full" because the jacket does not fully encase the lead.

And, yes, it's an exoskeleton in so many obvious ways, it's really petty to take issue with Tesla calling it that. This whole ridiculous "it's not an exoskeleton" is either a shameful attempt to minimize what Tesla has accomplished here, or a blatant display of ignorance of how the Cybertruck's chassis is engineered.

Why don't you just admit your original objection to the term "exoskeleton" was just plain wrong?

You had no real basis to assert that claim to begin with.

ugh, fine:

Bonus VHB Tape being used:

Thanks. That's the front fender which does nothing, and not the rear SS fender. But if the rear is the same, that backing won't transfer much load the way it came apart. In fact I'd say it's like that to avoid warping from the aluminium cast thermal expansion underneath.

P. S.
I'm actually surprised how much steel backing is on that front SS fender. Probably had to keep it thin for crash worthiness?

I've watched Kyle's video, and even posted a bunch of photos of it along with my commentary, but I didn't find anything in that one either.

The closest we got is where the admin posted a picture of the semi-assembled CT frame, where one side of the skin was on, the otherside missing. I asked if he could walk around and take a photo of the back, but I dunno where he was getting the footage from that he was posting.
