Heim Joint is an extremely rigid articulating joint, commonly known as a ""spherical rod-end,"" used in any precision linkage. Heim joints are often used in the suspension links of race cars because they locate wheels very precisely.



Sorry, Im bored and figure I would join in....

 

YES.....couldn't find a pic....thanx Yeti! that's it!

yea man...no prob! lol 85351Ho....yea that's him! we try

the rear axle doesnt move straight up and down, as the springs compress it moves back, and when they droop, it moves foward, ladder bars run without a shackle hinder your articulation pretty good, with a properly designed shackle, you would lose like 10 points on an rti ramp or sumthin ....one of my buddies in engineering down here is trying to design a bar that does not need a shackle

theoretically if you make the bar the right length and right angle, it will move at the same arc the axle does....think about it for a min.....but what do i know, my head hurts alot right now(kegs r the devil)

oh, thanks for the compliments guys

 

Its already been done

 

i wasnt implying it hadnt.....but if we can figure it out for ourselves.....it makes it cool.....you know...

 

Yea...thats one of the major innovations of my new design...its uses a slip yoke instead of a shackle. Its starting to look like my original concept of selling it for a hundred bucks is way off though. I dunno...I got too many projects, too little money, and now a krispy kremed tranny

 

i thought about useing a slip yoke setup...but it just dont know....im ready to get rid of my solid mount crap now though

 

What are you talking about using a slip yoke?
sorry to ask

 

I probably shouldn't be talking about it, since I want to sell it, but since its patented wtf. Picture a ladder bar with a fore mount that instead of attaching to a shackel, is attached to a solid mount via a heim joint using one heavy tube that has zirc fitting in it. Fit inside of the tube, which is greased via the zirk fitting, is the solid bar that flares into two that becomes the body of the ladder bars, much like in the pic of my old ones. The body of the ladder bars then connects to the axle. Now, as axle wrap occurs, the force coefficients are perpendicular to the slip joint which in effect cause it to bind, thus eliminating axle wrap. However, as the axle droops in articulation, the force coefficients are parrelel with the slip joint, and it can slid out as far as the axle drops and back in as the axle resumes its normal position. This design reduces articulation by a grand sum of zero. My original design had heims where the ladder bars connected to the axle too, much like a four link, but these are being found out to be uneccesary, as the ladder bar can also rotate in the slip joint, and the one heim up top is enough. I'd thought about making and selling them myself, but the cost of hand fabbing them is prohibitive, where if I sold the design where they could be mass produced the cost would be much cheaper.

 

Yeah, I follow. That was sorta my idea of what it should be, but I wasnt going to go as far as putting the zirc fittings on there. I wasnt going to make it with heims at either end either. I may do zirc if a local tractor supply has the right size and all, but thats one more grease point on my truck, and its nice not having many on there, when compared to a tractor (usually about 25).

Oh well, I guess I'll be fabbing them this weekend, so i might post pics later.

Thanks fr your help Pro...
