presne tak + aby to fungovalo, tak zlty kruzok ma tie drazky vnutry tensie ako su protikusy v modrej kam zapadaju = zlty kus sa pohybuje po inej drahe, ked ide do zaberu, ako ked ide do volnobehu.Trecia sila pruziny opretej o zlty kruzok (pri volnobehu zlty kruzok stoji ale pruzina rotuje spolu s nabojom) pri volnobehu tlaci zlty kus do polohy (voci modremu), kde vzhladom na nizky uhol ho samotna pruzina nie je schopna dotlacit do zaberu. Zaroven tato sila, pri zacati slapania zabezpeci, ze zlty kruzok sa pootoci (voci modremu) a pruzina ho potom lahko dotlaci do zaberu.
Ten "marketing" som sice prestrelil ja, ale teraz skutocne pravdu nemas ty.

0045 As seen in FIGS. 4 to 6, a biasing member 34 is disposed between the hub shell 16 and the first ratchet member 31. The biasing member 34 biases the first ratchet member 31 in an axial direction D1 toward the second ratchet member 32. The biasing member 34 is, for example, a compression spring in the illustrated embodiment. Preferably, the biasing member 34 is configured to rotate with the hub shell 16. As explained later, during coasting, the first ratchet member 31 is moved in an axial direction D2 toward the hub shell 16 when the sprocket support body 30 stops rotating or moves in a non-driving rotational direction relative to the hub shell 16.

Anglicky text len popisuje stav pri volnobehu, ale nie jeho pricinu. Odkial si vzala toto tvrdenie: "pružinka posúva ten krúžok ratchet č.31 smerom k telo náby" ? V tom citovanom texte to nie je.
Ja tam inde vidim napisany presny opak toho co tvrdis - ratchet c.31 pruzinu c.34 stlaca vid. hrubym.
Pricina pohybu 31 k naboju je ta sikma plocha 46 (co je samotna podstata toho Shimanackeho vylepsenia a patentu ako takeho)
In particular, the guiding portion 46 is configured so as to release a meshing engagement between the at least one first ratchet tooth 52 and the at least one second ratchet tooth 62 while coasting. The first ratchet member 31 contacts the guiding portion 46 and disengages from the second ratchet member 32 by a second thrust force caused by friction torque between the biasing member 34 and the first ratchet member 31 while coasting. The first helical spline 54 of the first ratchet member 31 abuts the second surface 46 a of the second helical spline 46 of the sprocket support body 30 by the sliding torque. Then a coasting thrust force arises so that the first ratchet member 31 moves against the force of the biasing member 34. As a result, the first ratchet teeth 52 of the first ratchet member 31 do not contact the second ratchet teeth 62 of the second ratchet member 32 during coasting.
