Nice video but you forget something :

There are two types of independant suspensions.

1 : independant suspension like our car use ( the wheel stays parallel to the ground, like the 8297 set)
2 : independant suspension like tatra ( the wheel doens't stay parallel to the ground)

Yeah, but the end result is same. Also real cars dont use neither, but macpherson, which also acts differently.

This is called double wishbone and uses a 4 bar linkage. Like this:

This is called swing arm. Like this:

Generally, only front wheel drive cars use Macpherson struts. Lots and lots of cars use double wishbone on the front wheels and many on the rear as well. Most front wheel drive cars with independent suspension use double wishbone on the rear. Older cars and trucks used leaf springs and a live axle. A few muscle cars used a trailing arm on the rear.

Exactly.

Sorry for the name but i just know it in french and not in english and i won't say stupid things.

Thanks u for informations.

in which category do you would set a massive axle with torque tubes like this?

Would you call it a "live Axle" or is it a own category?

Very nice and informative vid. The instrumental version of Madonna 'Live to Tell' soundtrack definitely makes this a very enjoyable vid too As you mentioned that live axle is more desirable due to better flexibility (which I agree), why does Tatra still uses the swingwarm and backbone chassis for their trucks? Is there a certain advantage of using this suspension in a 6x6 or 8x8 configuration?

@Efferman, yeah still live axle.

@Out Of Sight IMO indpendent suspension is sufficient for trucks with more than 4 wheels. Independent suspension is better for high speed and can be more stable.
