Described brake disc body is also provided with dismounting tapped hole.
The center of described dismounting tapped hole and the distance of described brake disc body central are less than, the distance at the center of described brake disc fixed hole and the center of described brake disc body.
Described brake disc mounting hole is two, and arranges with the Central Symmetry of described brake disc body.
Described brake disc fixed hole is two, and arranges with the Central Symmetry of described brake disc body.
Described dismounting tapped hole is two, and arranges with the Central Symmetry of described brake disc body.
A kind of brake disc extracting tool, is applied to the brake disc of above-mentioned any one; The spanner portion including demounting bolt and be fixed as one with described demounting bolt;
Described demounting bolt includes bolt shank and is positioned at the bolt head of bolt shank one end; The sidewall of described bolt shank is provided with outside thread; Described bolt shank and described dismounting tapped hole screw-thread fit;
Described spanner portion and described bolt head are fixed as one structure.
Described spanner portion is anistree indent flower type structure.
Described bolt head is polygon structure.
The beneficial effects of the utility model are:
By designing the removal tool special of a kind of quick detachable brake disc and this brake disc, under brake disc and hub corrosion situation, under not damaging brake disc and hub situation, conveniently can be pulled down, change and easy to maintenance.

Embodiment
Describe the technical solution of the utility model in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to technical solutions of the utility model.
The utility model provides a kind of brake disc, as shown in Fig. 3, Fig. 5 and Fig. 6, includes brake disc body 11, and the center of described brake disc body 11 is provided with through hole 12; The structure of brake disc body 11 is not improved with prior art.
The brake disc body 11 of described through hole 12 is provided with brake disc mounting hole 13, is through hole, for passing the Wheel set bolt on knuckle hub 20; Brake disc fixed hole 14 is counter sink, is fixed by brake disc body 11 by fixing bolt with knuckle hub 20; Brake disc positioning hole 15, for brake disc body 11 and knuckle hub 20 are located, convenient installation.
Described brake disc mounting hole 13 is two, and arranges with the Central Symmetry of described brake disc body 11; Described brake disc fixed hole 14 is two, and arranges with the Central Symmetry of described brake disc body 11.
It is circumferentially same that the center of the center of described brake disc mounting hole 13, the center of described brake disc fixed hole 14 and described brake disc positioning hole 15 is all positioned at described brake disc body 11 center;
Described brake disc body 11 is also provided with dismounting tapped hole 16.
The center of described dismounting tapped hole 16 and the distance at described brake disc body 11 center are less than, the distance at the center of described brake disc fixed hole 14 and the center of described brake disc body 11.Described dismounting tapped hole 16 is two, and arranges with the Central Symmetry of described brake disc body 11.In the present embodiment, dismantling tapped hole 16 is two M8 tapped holes.
A kind of brake disc extracting tool, as shown in Figure 4 and Figure 5, is applied to the brake disc of above-mentioned any one; The spanner portion 19 including demounting bolt and be fixed as one with described demounting bolt;
Described demounting bolt includes bolt shank 17 and is positioned at the polygonal bolt head 18 of bolt shank 17 one end, and in the present embodiment, polygonal is hexagon, and in other embodiment of the application, the limit number of polygonal bolt head can set as required.The sidewall of described bolt shank 17 is provided with outside thread; Described bolt shank 17 and described dismounting tapped hole 16 screw-thread fit; In the present embodiment, the diameter of bolt shank 17 is identical with the diameter of dismounting tapped hole 16, is M8 bolt; The length of bolt shank 17 does not have clear and definite requirement, but the length of bolt shank 17 is at least greater than the thickness of brake disc body 11, could realize the function of this extracting tool like this.
