Embodiment
As illustrated, a kind of brake gear for being fixed on bicycle contact pin groove described in the embodiment of the present invention, including：Such as figure
3rd, shown in Fig. 4, the middle part processing interstitial hole 51 of brake disc 5, the left and right sides of brake disc 5 processes left part projection 52 and right part respectively
Reinforcing sleeve 54, locating slot 53 is machined with left part projection 52, and the right side of brake disc 5 is also connected with brake circle 55；As Fig. 6~
Shown in 8, through hole 61 is machined with location-plate 6, the size of through hole 61 is consistent with interstitial hole 51, and one end bending of location-plate 6 is formed
Folded plate 62, insert plate 63 is processed on folded plate 62；As shown in figure 5, the left side processing contact pin groove 91 of vehicle frame 9, contact pin groove 91 and insertion
