Detailed description of the invention
As shown in Figure 1, bicycle brake device, comprises main shaft 16, protection plate 1, brake assemblies and control setup.
Described brake assemblies comprises: rotatable sun gear 4, and described sun gear 4 is arranged on main shaft 16, and can reliably rotate by bicycle quick;
For the miniature gears 3 engaged, described miniature gears 3 is arranged on sun gear 4 outer rim;
For the meshing flake 2 braked, described meshing flake 2 is arranged on miniature gears 3 outer rim, and described meshing flake 2 is opening;
Described control setup comprises: for the ratchet otic placode 6 connected, and described ratchet otic placode 6 is arranged on meshing flake 2 rims;
For controlling the articulated pole 7 of ratchet otic placode 6, one end of described articulated pole 7 is arranged on ratchet otic placode 6, and the other end is connected 12 with brake hand;
Described brake hand is connected with ratchet otic placode 6 12, and described brake hand is provided with iron wire bar 10 12 inside and is connected with articulated pole 7, and described iron wire bar 10 is connected with bicycle handle bar through pull bar 9.
Described protection plate 1 is surrounded brake assemblies and is arranged on main shaft 16.
Described meshing flake 2 inside face is provided with engaging tooth 14, and described meshing flake 2 opening outer surface is provided with installation sheet 5, and described ratchet otic placode 6 is fixed on installation sheet 5 by bolt of rear end plate 15.This meshing flake 2 is mainly used in engaging with miniature gears 14, makes miniature gears 14 inwardly in rotary moving; Installation sheet is used for fixed ratchet wheel otic placode 6.
Described pull bar 9 one end is connected 12 with brake hand by spring 8, and described pull bar 9 other end is connected with iron wire bar 10.Spring 8 connection has buffer action, in case cause damage when sudden forces to iron wire bar 10 and pull bar 9.
Described articulated pole 7 is arranged on ratchet otic placode 6 with brake hand on 12 by bearing pin 11.This connection mode facilitates indirectly, easily dismantles.
