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.
