The specific embodiment

Shown in Fig. 2,3,5, the colored hub fabricate block preferred embodiment of the utility model dress disc brake sheet easy to break includes the disc brake sheet 80 that a housing unit 70, is sheathed on housing unit 70, and a spiral shell is located at the lock ring piece 90 that housing unit 70 also can be suppressed disc brake sheet 80.

Housing unit 70 comprises having first a section portion 711 being reverse setting and a body 71 of second section portion 712, two spoke installation portions 72 from first section portion 711, second section portion 712 respectively along a radial outward moulding, one is arranged at the inner plug tooth portion 74 in second section portion 712 vertically, and an internal thread segment 75 that is arranged at inner plug tooth portion 74.In the present embodiment, inner plug tooth portion 74 has eight projections 741 and eight grooves 742, and internal thread segment 75 is to be arranged at eight projections 741.

Disc brake sheet 80 comprises a video disc 81, and is arranged at several projections 82 of video disc 81.

Video disc 81 has a line of centers 811, centers on line of centers 811 respectively and is an inner loop-line 812 and a Section of Outer Ring Line 813 that does not wait path length, reaches first side 814 and second side 815 that connect inner loop-line 812 and Section of Outer Ring Line 813 and be reverse setting.
