Rear Anti-Roll bar in iveco 6X6 Trakker

[mohammad_444_0o]

Hello dear friends,
I'm studying about the "Anti-Roll Bar" (ARB) in heavy trucks; I have downloaded multiple catalogues from

http://www.pktrucks.com

All of the models have anti-roll bar both on front and rear axles, EXCEPT the 6X6 iveco Trakker named (AD / AT 380T38 WH)...!
I don't know why???
6X4, 4X2, 4X4, 8X4, 8X8, even similar vehicles from other companies have both front and rear ARB...
.

I want to know if there is any technical information about "WHEN and in Whcih situation" the Rear anti roll bar can be added to the 6X6 rear axle???
Because the driver tetsted it and has big roll angles

I will be thankful if you guys help

This is a question for the manufacturer of the vehicle.

That particular brand of vehicles is not available here. BUT. Heavy trucks here ordinarily do not have antiroll bars. With leaf springs (which that brochure says is on that truck) they simply calibrate the springs very stiffly so that it isn't needed. Of course, this results in a rough ride. With air springs, the design of the suspension pretty much locks the left and right sides together (if the left side goes up, the right side is forced to go up, etc) except for deflection of bushings and locating mechanisms when one side tries to do something different from the other (e.g lean in corners or one-wheel bump). Those parts are very stiff, thus serving an antiroll function without actually having a separate antiroll bar.

What are you trying to do that warrants this investigation?

dear @BrianPetersen
I want to know if there is any datasheet, technical information, catalogue, standard, handbook, etc. to tell us in which condition, rear axle ARB can be installed as an extra and supplementary part of suspension system to compensate rollover?

Thanks dude.

OP said - " .... rear axle ARB can be installed as an extra and supplementary part of suspension system to compensate rollover? "

By rollover do you mean this ? -

Others far brighter than I will likely answer, but if you mean vehicle rolling over, I don't think ARBs can do very much to prevent that, unless load CGs are way above above the road surface.
