Barack Obama linked 2nd gen. SAS

Alright. thanks for the quick reply. This helps a lot

Oh and just to clarify, that pic was taken with the front axle removed from the vehicle, so all driveshafts and links are just danglign or resting on the ground and not at proper angles.

 

[colindo94]

ok It seems like what was going on. So what did your anti squat and roll axis numbers come out being?

 

[IZwack]

I dont think roll axis can be easily calculated with a leaf spring setup in the rear. However, on a linked supension roll center is typically just the panhard mount on the axle.

As for the anti-squat (or "anti-dive" when applied to the front), it came out to be a little on the high side, something like 130-ish or so. The constraint of this number of course is the chassis end of the link - you can only separate the two links from each other so far (and the angles are limited too). This is one of the reasons why I would really love to build a buggy instead of the Explorer - everything can be at the right dimensions and right config, where as the Explorer is mostly a bunch of compromises due to the existing frame rail, engine location, the bends on the frame rail and so on...

 

[colindo94]

Yea but I guess that goes for any kind of truck or SUV'S. I mean they wern't really ment to do the things we do with them. A buggy is built specific. That was close to the same number I was getting when I was calculating with a longer upper link. I feel a little better now. It's starting to sound like the link calculator isn't a very helpful tool (at least for our application).

For me, the link calculator was more of a simulator than a design tool. Like what characteristics does moving the upper link 2-inches vertically do, and so on. You can use the link calculator to basically get a rough estimate of what the vehicle will be like. But using it to tweak the Explorer's setup to the dream config is almost impossible because, again, the Explorer's dimensions and so on, limit the component's position and geometry.

What I found more useful are the many 3 and 4 link theory articles on PBB that includes many of the lessons-learned and what has worked for some people and what has not.

like you said, from what I read a lot of them realized that the calculator isn't really close at all. They ended up scrapping it and just used trial and error.

 

[IZwack]

... the calculator isn't really close at all. They ended up scrapping it and just used trial and error.

Yeah.

Which is kind of unfortunate for us because similar calculators work so well for road suspensions, and here we are kind of blindly putting together trial and error configs -- which just wastes time and $$.

So I think as long as you stick with the fundamentals (mostly from the PBB threads) and a little bit of common sense, then anyone should be able to setup a "good enough" configuration (not a competition configuration of course) on an Explorer. On the other hand, one thing I always like to see is ingenuity and people trying different things, and maybe even coming up with new and wild approaches to how things are set up -- you know, going outside of the "box".

Please, I beg you, drop out of the presidential race.............the country is in enough trouble already.: I heard you will not pledge allegiance to the American Flag, and were raised in a family that pratices the most violent, anti-American sect of the muslim faith. And your middle name is "Hussein". Its probably just all right wing propaganda though.

Ahaha Hi Mr. Kennedy

Yes you got it correct, its mostly right wing propaganda. But I, Barack Obama, am saddened of the political party entrenchment which we've barricaded ourselves in. This is an America by the people and for the people, not an America rulled by Republicans or Democrats. And as such, labelling ourselves party A or party B is just another form of segregation -- which many in history such as MLK have laid down their lives fighting. So having said all that, I'd say its not so much as right wing propaganda, but hateration propaganda -- they need to put down the Haterade and get back out in the communities actually helping out the average Joe.

 

[BKennedy]

Thanks, had a good laugh! Watching you walk the ridges at Truckhaven makes me wonder about your presidential fortitude. Or, maybe it was just misdirection, making me think I should wonder about your presidential fortitude......hmmmmmmmm.................hmmmmmmmmm..........must ponder this for awhile.
Nice speach by the way, you only contridicted yourself a few times in each paragraph. You should go out drinking with my uncle Teddie, he is a real party animal. Just don't let him drive across any bridges.

Yo Barack, any updates/pics of that D60?

 

[IZwack]

Yo ZainyD! Nope sorry the dana 60 is just chilling in the basement. I haven't even bought a single part for it yet. But no worries cauz its still January. I'll start buying parts in a month and it should still be on schedule for a spring or early summer install.

But the 44 on the other hand just snapped another axle shaft last Sunday. I tried climb up a 3ft vertical concrete form with some pretty slipperry stuff under it, kept pushing and pushing and BAM, the axle shaft said "you know what, I'm going to chillax right here".

Crappy pic:

geeez. Thank God i went straight to a 60.

The problem is that the Explorer is too heavy -- man I need to build a bugeeeeyy

 

[FROADER]

Build that white thing in the front yard... :

 

[IZwack]

The white thing right derrrr.. I know you like it right derr right derrr -- snaps.

But to be serious, the white thing is at my friend's backyard, collecting spideyss..

Yeah i know. Right now without any junk in my mounty and with little under 3/4 tank full of gas im weighing in at 5870 pounds. Add a full tank of gas when i wheel, spare front shafts and u-joints and tools as well as a spare tire im prolly tipping in at 6200 pounds.
