N=3 2R-Virtual Wheel (Reuleaux triangle-Frame)
Variation: N=3 2R-Virtual Wheel (Reuleaux triangle-Frame2)
cf. N=3 2R-Virtual Wheel (Reuleaux triangle-Frame3) --- auto vertical arm
Description:
This is a less friction Reuleaux triangle wheel. This is a home run works.
cf. N=3 2R-Virtual Wheel (Reuleaux triangle-Omusubi) ---- slant arm is OK.
in Z0H interval: AA [= arm upper position] is center. So, cyan MM traces arc. BMM is radius [rigid straight bar].
in HI interbal: A [= arm lower position] is center. So, cyan MM traces arc. DMM is radius [straight].
The linearity of pink hinge and blue hinge are exclusive relation.
Blue hinge is hanging/ pulling device , so no need to be straight. it becomes straight automatically.
But, Pink straight bar is not hanging ( is pushing).
----- Can you understand what I want to say?
[Straight pink bar AA-MM must be very strong bar, because AA is wheel center, AA-MM endures the heavy weight.]
How to keep the radius control ? ------ Introduce the dynamic lock mechanism. Do have a hat to Node B/ C/ D.
Result was in avobe Fig. It's very simple & good result. I think so.
Features:
① Arm must be vertical. (--- slant arm doesn't work.) [roof is horizontal, so, I recommend pair wheels.]
② Distance control from wheel center to the vertical arm top and bottom.
③ Bicycle is the r= from 1R to 2R converter.
(usual wheel has a center at middle height, but above real center is at top height. -- like to biped.
cf. Musashikoganei Bicycle --- i.e. Walking Bicycle)
■ Is there exists when B/C/D is not on AA and AA-MM is straight?
If so, more restriction must be needed.
Please answer my question. And please prove it.
GA ( wheel ground touching point).
Evidence: GA and the one of B/C/D are always on the same vertical line.
(So, if wheel is on the ground, one of B/C/D is just on AA or A, always. Circle property ensures this fact. )
■ Bicycle
Please compare my above bicycle and other method bicycle.
cf. Reuleaux Wheeled Bicycle ----- much friction, & noisy.
■ dolly caster
Please compare above dolly/ cart and other method dolly.
cf. Inventing the wheel ----- much friction. --- 100% friction method.
