pull/pushrod suspension

[gt1guy]

What I meant by the 45* angle was that you want to get that pushrod as close to vertical as you can. I would say that 45* would be the min, anything closer to 90*(straight up and down) would be better. Hope this clears it up.

I've seen link set ups like your building before. But, the distance between the ends of the forked side were always much, much greater. Some have the forked link on top, most have it on the bottom. Basically what your building is a modified version of a Satchell link suspension. And as such, the third link NEEDS to be as wide as possible, the forked legs of said link NEED to be a as close to a 45* angle in plan view as you can get them. Nature likes triangles. This is really not an option, the forces that that link will see are very high to say the least. I can't stress this point enough. Instead of thinking of it in terms of it keeping the rear end under the car, think of it as it has to keep the entire car over the rear end. That's the kind of forces were talking about here. Having the forked side only as wide as the 3rd member won't do it.

Here's a couple pic to show you what I'm talking about:

This is what your building. But like I said, it has the forked link on the bottom,as most do. Notice how wide it is, almost the width of the rear end.




Now hear is JAGs true Satchell link. Again, notice the spread in the lower links. It's no accident that they truly look the same. It's also no accident that they are at 45* angles.



Hope this helps to shead some light onto the point I'm trying to make.
