See also Fig. 1,2, shown in 3, a kind of disc brake apparatus that is installed on the bicycle of the utility model, this structure is provided with a wheel shaft 20, this wheel shaft 20 is positioned on the wheel center position of bicycle front-wheel or trailing wheel, these wheel hub 20 both sides respectively are provided with relative 1 wheel disc that combines with it 21, wheel disc 21 peripheries respectively are provided with a plurality of equidistant perforation 211, be coated with spoke 22 respectively in the perforation 211, spoke 22 also is radiation-like and is extended to wheel edge (not shown) by wheel shaft 20, and this wheel shaft 20 is equipped with outward extending axostylus axostyle 23 outside wheel disc 21, screwed togather a cap 24 on the axostylus axostyle 23 respectively, moreover, this wheel shaft 20

wheel disc

21 and 24 on nut of a side therein is arranged with a disc 10 respectively, this disc 10 also is locked together in a disc brake sheet 12 by screw rod 11, this disc brake sheet 12 be positioned at disc 10 not with one side that wheel shaft 20 is attached to mutually on, and these disc 10 peripheries are provided with the screw hole 13 of at least one, this screw hole 13 is provided with a mat screw rod 14 and is locked together in connecting piece 30 on the disc 10, as shown in Figure 2, these connecting piece 30 1 ends are provided with a perforation 31, to make screw rod 14 can pass this perforation 31, and connecting piece 30 1 ends are fixed on the disc 10, the connecting piece other end is then established caulking groove 32, and this caulking groove 32 just can be buckled on the spoke 22.

During installation, see also Fig. 1,2, shown in 3, can be with nut 24 spiral shells from axostylus axostyle 23, the disc 10 and the disc brake sheet 12 that are locked together in together are set on the axostylus axostyle 23, after pitching the fork arm 40 of vehicle frame on the axostylus axostyle 23 that is enclosed within wheel shaft 20 both sides respectively again, this nut 24 is locked together on the axostylus axostyle 23, so, fork arm 40 is fixed on the wheel shaft 20, and makes disc 10 be interposed in

wheel disc

21 and 40 of fork arms wherein, again with at least one connecting piece 30 1 end buckle on spoke 22, sealed by screw rod 14 again, these connecting piece 30 other ends are fixed on the disc 10, so, disc brake sheet 30 can be fixed on the front or rear wheel of bicycle easily.

In addition, this wheel shaft 20 is embedded with a clamp adapter plate 50 at arbitrary side shaft bar 23 contiguous fork arms 40 places, this clamp adapter plate 50 is provided with clamp 60 at appropriate location, these clamp 60 just can be embedded on the disc brake sheet K of disc 10, when making disc brake sheet 12 rotate with wheel shaft 20, can be by the restriction of clamp 60, and slack, and then reach the purpose of brake.

In addition, these clamp adapter plate 50 1 ends are provided with an embedding hook 51, the other end then combines with a branch of bundle spare 70 that is combined on the fork arm 40, but with make this clamp adapter plate 50 not only mat embedding hook 51 clips on the axostylus axostyle 23 of wheel shaft 20, and stand on the axostylus axostyle 23, and can close by the bundle of bundle part 70, this clamp adapter plate 50 is fixed on the position, the unlikely position of departing from, and then clamp 60 can be embedded on the disc brake sheet 12 really.

Above-mentioned bundle spare 70 can be relative intermediate plate 71 and forms, intermediate plate 71 is respectively equipped with one and stretches out and post together flange 72, screwed togather a screw rod 73 (as shown in Figure 5) on the flange 72, or be a ring 74, these ring 74 two ends also can be locked together in together (as shown in Figure 6) by screw rod 73, or be a ring frame 75, this ring frame 75 is provided with and is interposed in together and outward extending projection 751, is equipped with a screw rod 73 (as shown in Figure 7) on the projection 751.

When installing with order, an end that earlier clamp adapter plate 50 is had embedding hook 51 is nested on the wheel shaft 20, make this clamp adapter plate 50 be interposed in 40 of disc brake sheet 12 and fork arms, again clamp adapter plate 50 other ends are locked together on the bundle part 70, this bundle spare 70 can be set on the appropriate location of fork arm 40, makes this clamp adapter plate 50 can be supported by on wheel shaft 20 (as shown in Figure 3), so that clamp 60 can be at clamp adapter plate 50 is fixing, and be fixed on the certain position, make and 60 unlikely departing from the position of clamp.
