Re: Designing rear anti-roll bar brackets for my R
Mark,
Aluminum brkt. #1 gets a lot of strength, in the same direction as the welded plate, from the center rectangular piece and all 4 through bolts/spacers. If you look at it as an assembly the through bolts combined with their spacers all have substantial material in the same plane as the welded plate.
If you go on the assumption that the original design is sufficient any added strength gained from a brkt that primarily functions as a link mount is just icing.
Here's Brkt. #3 with a mod to eliminate the upper heim spacers and just use washers. Unlike the lower A-arm heim I think the sway link heim has some pivoting in both directions but still not enough to require a high clearance spacer.
This variation is going to require more cutting and more welding but less spacer machining. Probably an even trade off in labor. Not sure about the strength difference, probably the same there also.
Once again the yellow and blue is the same .095 mild steel, different colors for visibility.
