You’d need a double linkage parallelogram thing so that turning isn’t affected.
Single pivot suspension is I think just a no go.
With the double linkage, I think it would be pretty easy to set up to compress urethane rather than a spring. If you were to aim for like, even 4mm of suspension travel, with like 1.5mm of sag that’s actually a lot for any sort of skate truck.
Would probably easier to do a proof of concept design as a channel truck, since they’re so much easier to mess with. I mean, you can make a channel truck using only square tubing, angle bar, and welded on nuts for a thread in axle.
If you can get two sized of square tubing, one that fits snug inside the other, that’s probably a really good way to make the linkages.
I think I might have a solution to keep the suspensions mount always 0° even if truck / KP angle is regular 40-50° but I don’t have enough input yet on how to keep the wheel axles parallel to ground yet to complete a schematic.
Trying to learn on this to avoid the “camber effect” which would reduce wheel patch under compression.
@b264 if we keep the wheel contact patch the same as regular truck without angle or position deviation, this would be good then?
I don’t think its all that important to address honestly, especially for the front truck as forces are coming in at an angle anyway. The biggest thing is it means your linkages will need greater travel than your suspension travel, and they’ll need to be a bit more robust torsionally.
What do you think about making this suspension attach to a block that fits over the end of a @Boardnamics hanger. Basically just bolts on to the axle thread lol.
Then my special idea to prevent bending is you would put a crossbar between said parts bolted on the ends of the hanger.
thanks for the sketch btw!
