Anti-Roll bar in 6X6 Trakker
(OP)
Hello dear friends,
I'm studying about the "Anti-Roll Bar" (ARB) in heavy trucks; I have downloaded multiple catalogues from 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

RE: Anti-Roll bar in 6X6 Trakker
I have read accounts of fleet vehicle buyers being cheated (their words) out of ARBs by suppliers who executed the required tests (e.g. slalom through a line of cones) using a skilled driver who had no apparent difficulty doing so, but then finding their fleet drivers were unhappy with the vehicles' handling in service.
I am not in the vehicle business, but I am not aware of a general specification that specifically requires ARBs. It is, here in The Colonies at least, up to the buyer to specify exactly what is desired, or to require performance tests as mentioned above, with acceptance criteria that indirectly force inclusion of ARBs, or whatever features are required.
Perhaps IVECO thought that roll stiffness was not a major requirement for a 6x6, or maybe they thought that too much roll stiffness would lift a wheel on difficult terrain, when the wheel's tractive effort was very much desired.

But I have read many catalogues of heavy trucks and the result is that almost all of them have anti-roll bar (front & rear).
what do you think of why only the 6X6 doesn't have ARB on rear axle???
RE: Anti-Roll bar in 6X6 Trakker
So if ARBs are useless in heavy vehicles, why are they used in almost all catalogues of trucks?
I will be thankful if you take a look at pktrucks.com Go to chassis cab or tractor vehicles...
You will see in catalogues that almost all have.
Thanks if you think about it and explain why?

Actually I want a technical guide to when the supplementary rear axle ARB can be added?
RE: Anti-Roll bar in 6X6 Trakker
What have your calculations told you about total roll stiffness needed and distribution front and rear and frame strength? If this is not in your skills inventory, leave it up to the manufacturer.
