Description

brake disc

This creation is related to brake discs.

The braking force is generated through the friction force of the caliper to brake the brake disc to achieve the purpose of braking. The disc can be divided into a fixed disc and a floating disc. The industry has developed a floating disc to solve this problem. A general floating disc includes an inner disc, an outer disc and a floating buckle. The floating buckle is used to connect the inner and outer discs. When the outer disc is squeezed by the caliper, it can be pressed accordingly. A slight offset allows the pads to fully engage for better braking performance.

However, the structures and functions of the floating buckles used to connect the inner and outer discs on the market are too simple, which makes the connection relationship between the inner disc and the outer disc not accurate and single, resulting in insufficient activity margin for the corresponding offset of the outer disc.

Therefore, it is necessary to provide a novel and progressive brake disc to solve the above problems.

The main purpose of this creation is to provide a brake disc, which can effectively and stably assemble the inner disc and the outer disc.

To achieve the above purpose, the invention provides a brake disc, including: a disc main body, at least one first limiting mechanism and at least one second limiting mechanism. The disc main body defines an axial direction, the disc main body includes an inner disc and an outer disc, and the outer disc surrounds the inner disc; the at least one first limiting mechanism includes a first insertion portion, a second insertion portion Connecting parts, a plurality of baffles and a plurality of first riveting parts, the first insertion part is set on the outer plate, the second insertion part is set in the inner plate, and the plurality of baffles are respectively on the opposite two sides of the main body of the disc. The first inserting part and the second inserting part are interposed on the side, and the plurality of first riveting parts pass through along the axial direction to rivet the plurality of retaining pieces and the disc main body; the at least one second limiting mechanism includes a The second riveting part is pierced along the axial direction and riveted to the disc main body, and the two ends of the second riveting part interfere with the inner disc and the outer disc respectively in the axial direction.

The following is only an example to illustrate the possible implementation of this creation, but it is not used to limit the scope of protection of this creation. The "one" or "at least one" before the nouns mentioned in the article does not limit the number. It can also be "plural" according to the needs, and the change in the number is also within the scope of protection, which will be described first.

Please refer to FIG. 1 to FIG. 6 , which show an embodiment of the invention. The brake disc of the invention includes: a disc main body 1 , at least one first limiting mechanism 2 and at least one second limiting mechanism 3 .

The disc body 1 defines an axial direction 41 and a radial direction 42 . The disc body 1 includes an inner disc 11 and an outer disc 12 , and the outer disc 12 surrounds the inner disc 11 .

The at least one first limiting mechanism 2 includes a first insertion part 21, a second insertion part 22, a plurality of blocking pieces 23 and a plurality of first riveting parts 24, and the first insertion part 21 is arranged on the outer plate 12. The second inserting portion 22 is disposed on the inner disc 11, and the plurality of retaining pieces 23 are respectively sandwiched with the first inserting portion 21 and the second inserting portion 22 on two opposite sides of the disc main body 1, The plurality of first riveting parts 24 pass through and rivet the plurality of retaining pieces 23 and the disc main body 1 along the axial direction 41; The spaces defined by the plurality of baffles 23 are relatively movable, so as to achieve the purpose of floating the outer plate 12 relative to the inner plate 11 .

Furthermore, a plurality of the first limiting mechanisms 2 are arranged at interval angles so that their center of gravity is located on the axis 13 of the disc main body 1 (such as arranged at equal angular intervals), so that the entire brake disc The disc rotates steadily.

It is worth mentioning that the plurality of first riveting members 24 of the two adjacent first limiting mechanisms 2 on the circumferential direction 43 are reversely penetrated along the axial direction 41 in order to adjust the center of gravity on the axial direction 41 position, and the plurality of the first limit mechanisms 2 are arranged at equiangular intervals in order to allow the position of the center of gravity on the radial direction 42 to fall on the axis 13, through the axial direction 41 and the radial direction 42 at the same time Adjust the position of the center of gravity in two different directions to achieve the effect of making the brake disc rotate more stably.
