Differential geek video

My inner geek loves this stuff. Just a simple video on the workings of a differential made years ago.
If you have a spare 5mins it's worth a look.

I remember this vid from years back. Great explanation and I love when things can be explained visually using analogies.
 
Love this sort of explanation Yorkie, you have probably already seen ones showing how a synchromesh gear box works - this is one of my favourites:

Glad its not just me who loves these ingenious explorations into the workings of the modern automobile :)
 
Couple of great videos there although I think I preferred the retro differential one

If you liked them two this is another interesting one showing how an LSD differs to a standard differential

You want retro - check this 1936 'spinning levers' car transmissions & synchromesh (car gears start at 3:00 mins in) :)
 
You guys need to get yourselves a nitro engined radio controlled truck.
No. I'm serious. I'm an adult too.
It is all these videos in wonderful tactile 3D. You gain an understanding in a few weekends fiddling with it that you won't get reading or watching animations.
 
A radio controlled car. It gives a lot of insight in mechanics of normal cars. Also wheel and shock alignment is easy to adapt on these things (much easier than a normal car obviously) and you can still experience what that does to vehicle dynamics and grip.

Although most of these things are equipped with a ball diff. A type of LSD diff (well sort of..) only RC guys know of and is not used on normal cars. ;)
 
I learnt all this when I was about ten playing with Lego Technic which uses proper gears and you build the differentials. You also build engines with crankshafts, conrods and pistons. I seem to remember my pneumatic truck with crane had a V8. :-)
 
Such stuff is cool. and imho actually helps drivers understand what's going on and leads to better car control

I've had to get deep knowledge of how 4WD works and the differences between, full time, part time, etc. When diffs can be electronically locked and when they must be free as 'open' diffs. Really interesting, especially when you consider that in reality most 4WD's are actually 1WD or 2WD, just as normal cars are 1WD

This is completely new to me, any more info or even a retro youtube video to explain :)
