Random name I just came up with, I will use it now for my version. PATs (ParAllTrucks) Reasoning is it sounds a bit like Parallel Kingpins but easier to have a different shortened name to call it.
Par in golf referring to a number of hit in a golf score. a bit like these have a number of bushing seats
All because they can be changed to do all the things I need.
If you wanted to be more general about the type of these rod end trucks you could call them PLL (ParaLlel Links)
These are also just PKP and 3links mixed slightly
I’m convinced there’s some genius to this that’s obscured behind its enormous complexity. Pardon my ignorance but can you elaborate on what needs you’re referring to? What does this construction add or solve?
Well it adds, the ability to add. More kingpins and bushings. A use case where it is mega helpful to have the most support possible is with Freeboarding and naturally the electric freeboards. People usually seek out the hardest available (96a) bushings and crank them down and it is still possible to desire more given the wide hangers and way you ride lol. If you look at the Leiftech freeboard modding thread I was talking about using the Apex airs and that made me think of that use case when I began working on this.
The way to make 0 degree trucks work on a Freeboard I can talk about later, not super sure about it yet but others approved the idea.
I got the idea that you could easily adapt the SRB NKP trucks to a 0 degree version by adding a second rod, it doubles the strength of the trucks in some ways and makes it so you can resist (like a literal) ton of torque.
glad you are here there is room for like a hundred motors on this things
it is just begging for a diff/gearbox to be built into the middle
I do know how to design a shifting gearbox for it! Pneumatic or servo based gear shifts
you would buy/handmake the parts you can and then if it is too much you cut part of it off.
What I have done for these triple bushing stack versions is move from a 1/2in rod end to a 10mm, this allows and idk maybe necessitates two, although the support of bushings is to be considered.
hmm I kinda put a restraint on myself and made it fit magnum bushings and not cut all the space between and made it only fit barrels which could be switched to… I wanted a single kingpin with magnums in the front to be possible.
Also the bushing seats being able to reconfigured from horizontal to vertical is interesting to me.
with vertical you do not have to worry about left and ride side bushing differences.
Did not get close to answering this. This design allows you two easily scale any part of the dimensions more or less. it can be scaled to the point of supporting massive loads. I could make a configuration that is perfect for the WheelEEZ Fosterqc projectie’z with the 30cm+ size wheels, those need some serious room to turn and compensation for height.
The kind of idea of sticking rod ends on a skateboard baseplate and trying to make an epic drivetrain certainly has a lot of ways it could end up. Most anything you could imagine I suppose.
One thing I think would be perfect to try on these is the Tracked drive module idea. I thought about making one that fits boardnamics/Torqueboards CNC hangers… these are just more suited I think due to the dual axles and large mounting plate built in right at the end of the hanger, instead of an adapter on the BN/TB trucks.
^In order to get that done I need to get the BN AT drive CAD files then make those parts mount on here, and start on the roller chain track drive modules. After I could adapt it onto the other hangers, maybe test it before I bother doing that.
The sheet metal angled attachment parts not yet designed would get rid of the deck interference.
or a riser lol, besides the trucks themselves having adjustable height you could use to solve this.
well if your deck angle the front it is gonna be pointed 30 degrees up so needing that adjustment. Good idea I like that. There are also all the m4/5 holes up top for stuff like that.
All the better to make a single modular truck that can suit the needs of my many board designs!!
Cool stuff been done!!
This reminds me to say these trucks can also fit channel truck style bushings
spending more to spend less, I like that but in reality we both know you’re too addicted to getting new parts and building boards don’t worry you’re not alone.
If the problem is extra leverage due to the increased arm length, then wouldn’t the solution be to decrease the arm length by placing the bushings closer to the wheels, and not in the middle? Although I guess that just becomes a channel truck at that point. And I’m guessing that doesn’t work for you for some reason or another
Shitty DIY and nothing else! or some Weird theories and ideas thread
don’t worry you’re not alone.
