just realized I can throw bearings on there so I get a roller instead of a slider. For a more durable/water resistant design this metal/plastic on plastic idea would be perfect on a Freebord or beach board. your truck steering can also now be jammed on a pebble. Nice. sealed truckboxes when?
I will see if it makes more sense to have it on whichever side of the supermodularBNadjbaseslider. huh slider on the slider base, on a sliding board. Sounds slick.
What I was thinking about is having good return to center.
on a Freeboard where I want to use these ideas you can never have a hanger get stuck more than a deg or two off center, they also need KRANKed bushings so return should be more than solid enough.
I was just considering the possible dangers to mitigate.
I have also been thinking about how to make something like a FB 5-X suspension with two NKPs that would be awesomely adjustable. I began thinking even about it may be possible to angle the rod out and run no guiding mechanism at all. (model I must)
That idea of having less than solid guiding led me to think about the axle sliding in a slot to constrain, as on a Freeboard there is no steering slop issues at speed really. Then I realised for the more normal design that you could have the slider constraint only acting from the boardside. I think this idea would work quite well scaled down, it is more simple than the dual rod design. To eliminate slot/slider slop I would try having some kind of spring/bushing preload on them.
I did not completely get this at first but I see now you mean the turn slop caused by the sliding constraint against the plate will have ever greater effect on stability approaching 0 degrees, where it is needed most. I suppose my dual NKP rod end config is superior in that respect of excellent movement constraint for stability in all positions.
I am not looking for high speed stability as the primary goal of everything I am thinking of. One thing that would be interesting is allowing that deflection on the slider constraint for some sort of suspension. Ok time to come up with some better ideas I guess.
Moe sounded like he meant two different things but in that pic they are defined to be the same. Maybe I am getting confused about something, well I am but idk about what.
again it sounded he said there is additional component of caster.
is this part of the geometry?
sorry @Linesflag I should have been more clear, I was not asking for help understanding the picture, the picture made what @MoeStooge said make no sense so I wanted to know what he meant.
Exploring possible small footprint trucks with high precision and adjustability because why not. Some of these ideas could be scaled down or up without changing much else also which I like for specialization.
if I were trying to make something smaller/cheaper overall I could use a fixed baseplate and move the pivot bearing location. (remind you of something???) Would have to lose the bushing tension to spin the axle unfortunately.
Overall theme is modular truck. Donât like something? Change it out.
I⌠honestly never realized dkp are actually dtkp. That kind of explains why i, as a long time rkp head, always preferred soft bushing rkp, qnd thought dkp felt wrong.
With this. I notice the slider for angle is at or near its max to one side, for the âzeroâ angle. But, i have very little understanding of the geometry of this kind of truck. What would be the effect of greater/lesser positive/negative kingpin angle on the setup pictured?
Adjusting the angle of the truck/rotation axis changes the steering ratio like every truck. it is more like a bolt pivot trucks discussed in awesome detail on Longboard technology
I need to model the smaller version that is where that slot/slider guided idea really shines. where there is no room for any rods or other bearings at all.
I am still messing around with putting a bearing there idk why⌠clearly it should be a urethane pivot cup.
Yeah so move the collars in and make one solid pivot knob and all that.
Yes, i more meant, what would be the ârecommendedâ angle.
Like, lets say it was on a flat deck, zeroed as pictured. I actually imagine it wouldnt quite do nothing, like zeroing an rkp or tkp would.
Vs
At that same âzeroedâ angle on a mountainboard deck that has 30° tails.
Vs
Adjusted/dewedged -30°
Just trying to gain a better frame of reference here. Id also like to know what would happen if you mounted the whole truck inverted, which i assume would mean that bit with a bearing was inside, not out, but i think i could infer that from the other question.
use case, idk why asking me a question like that while making very crude models makes sense.
Modular adjustable truck man. That is what we are talking about.
should work any which way. the thing being so damn short means running it literally top mounted may work. Gotta have some big wheels to need thatâŚ
You were in my thoughts earlier, removing the SRB NKP small rods on the axle and attaching the steering constraints onto the base NKP rod thread itself is my best idea yet for making raising COG.
