Description

Brake Disc

The present invention relates to a brake disc.

The purpose of braking is achieved by generating the friction force of the brake disc clamped by the caliper. The disc can be divided into a fixed disc and a floating disc. The fixed disc has the defect of not being able to fully engage with the brake pad, so 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 slightly offset accordingly, so that the brake pad can fully engage and have a better braking performance.

However, the structure and function of the floating buckle currently used to connect the inner and outer discs on the market are too simple, so that the connection between the inner disc and the outer disc is not accurate and single enough, resulting in insufficient activity margin for the corresponding offset of the outer disc.

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

The main purpose of the present invention is to provide a brake disc which can effectively and stably assemble an inner disc and an outer disc.

To achieve the above-mentioned purpose, the present invention provides a brake disc, comprising: a disc body, at least one first limiting mechanism and at least one second limiting mechanism. The disc body is defined in an axial direction and a radial direction, and the disc 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 riveting piece, the riveting piece is riveted to the disc body along the axial direction, and the two ends of the riveting piece interfere with the inner disc and the outer disc in the axial direction respectively; the at least one second limiting mechanism includes a first concave hole portion, a second concave hole portion, a first A screw connection unit and a second screw connection unit, the first concave hole portion is arranged on the outer disc, the second concave hole portion is arranged on the inner disc, the notch of the first concave hole portion and the notch of the second concave hole portion are mutually connected in the radial direction to form a set of connection holes, at least one of the first screw connection unit and the second screw connection unit passes through the set of connection holes and is screwed to each other, and a first blocking portion of the first screw connection unit interferes with the disc main body in the axial direction.

The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained in advance.

Please refer to FIG. 1 to FIG. 5 , which show an embodiment of the present invention. The brake disc of the present invention includes: a disc 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 . The outer disc 12 surrounds the inner disc 11 .

The at least one first limiting mechanism 2 includes a riveting member 21, which is riveted to the disc body 1 along the axial direction 41 to achieve the purpose of limiting with a simple structure. The two ends of the riveting member 21 interfere with the inner disc 11 and the outer disc 12 in the axial direction 41 respectively.

Specifically, the at least one first limiting mechanism 2 is plural in number, and the plurality of first limiting mechanisms 2 are arranged along a circumferential direction 43 of the disc main body 1. A rivet 211 of a rivet 21 of a first limiting mechanism 2 and a rivet 211 of another adjacent first limiting mechanism are respectively located at two opposite sides of the disc main body 1, thereby allowing the weight of the disc main body 1 on both sides in the axial direction 41 to be evenly distributed, so that the disc main body 1 can be more stable when rotating without shaking or swaying. Specifically, the plurality of first limiting mechanisms 2 are arranged at intervals, such as at equal intervals, so that their center of gravity is located on the axis of the disc body 1, so that the entire brake disc can rotate stably.

It is worth mentioning that the plurality of rivets 21 of the two adjacent first limiting mechanisms 2 in the circumferential direction 43 are penetrated in the opposite direction along the axial direction 41 in order to adjust the position of the center of gravity in the axial direction 41, and the plurality of first limiting mechanisms 2 are arranged at equal angles to allow the position of the center of gravity in the radial direction 42 to fall on the axial line of the disc body 1. By adjusting the position of the center of gravity in two different directions, the axial direction 41 and the radial direction 42, the effect of allowing the brake disc to rotate more stably is achieved.

Preferably, each first limiting mechanism 2 further includes a pad 22. The two ends of the rivet 21 are the rivet head 211 and a rivet tail 212 respectively. The pad 22 is sleeved on the rivet 21 and clamped between the disc body 1 and the rivet tail 212, so that the disc body 1 will not be damaged when the rivet tail 212 is press-riveted. The outer diameter of the pad 22 is larger than the outer diameter of the rivet tail 212, so that the force of the rivet tail 212 can be evenly transmitted to the disc body 1. Similarly, the pad 22 of one first limiting mechanism 2 and the pad 22 of another adjacent first limiting mechanism 2 are preferably located at two opposite sides of the disc body 1, so that the weight of the disc body 1 on the two sides in the axial direction 41 is evenly distributed.

The at least one second limiting mechanism 3 includes a first recessed hole portion 31, a second recessed hole portion 32, a first screw unit 34 and a second screw unit 35. The first recessed hole portion 31 is arranged on the outer disc 12, and the second recessed hole portion 32 is arranged on the inner disc 11. The recess of the first recessed hole portion 31 and the recess of the second recessed hole portion 32 are interconnected in the radial direction 42 to form a set of connecting holes 33. At least one of the first screw unit 34 and the second screw unit 35 passes through the set of connecting holes 33 and is screwed to each other. A first blocking portion 341 of the first screw unit 34 interferes with the disc main body 1 in the axial direction 41.

In this embodiment, the number of the at least one second limiting mechanism 3 is plural, and the plurality of second limiting mechanisms 3 are arranged along the circumferential direction 43 of the disc main body 1. The first baffle 341 of the first screw unit 34 of one second limiting mechanism 3 and the first baffle 341 of the first screw unit 34 of another adjacent second limiting mechanism 3 are respectively located on two opposite sides of the disc main body 1, so that the weight of the disc main body 1 on the two sides in the axial direction 41 tends to be evenly distributed, so that the disc main body 1 can be more stable when rotating without shaking or swaying. Similarly, the plurality of second limiting mechanisms 3 are arranged at intervals in angles so that their center of gravity is located on the axis of the disc body 1, such as being arranged at equal intervals in angles, so that the entire brake disc can rotate stably.

Preferably, the first threaded unit 34 is rotatably threadedly connected to the second threaded unit 35, and the user can adjust the force of the first threaded unit 34 and the second threaded unit 35 clamping the disc body 1 in the axial direction 41 after being screwed together as needed, thereby changing the margin for partial floating of the outer disc 12 relative to the inner disc 11.

More specifically, a second baffle 351 of the second screw unit 35 interferes with and blocks the disc main body 1 in the axial direction 41, and the disc main body 1 is located between the first baffle 341 and the second baffle 351. Each second limiting mechanism 3 further includes an elastic member 36, one end of the elastic member 36 elastically abuts against the disc main body 1, and the other end elastically abuts against one of the first baffle 341 and the second baffle 351. By means of different compression degrees of the elastic member 36, the purpose of changing the floating ability of the outer disc 12 relative to the inner disc 11 can be achieved. More specifically, the elastic member 36 of one second limiting mechanism 3 and the elastic member 36 of another adjacent second limiting mechanism 3 are respectively located at two opposite sides of the disc body 1 to achieve the purpose of weight balance.

Preferably, each second limiting mechanism 3 further includes a cover 37, which covers the elastic member 36. One side of the cover 37 abuts against the disc body 1, and the other side abuts against one of the first stopper 341 and the second stopper 351. The cover 37 can effectively protect the elastic member 36 from being interfered with or damaged by foreign objects.

Another preferred embodiment is that the total number of the plurality of first limiting mechanisms 2 and the plurality of second limiting mechanisms 3 is an even number; the number of the plurality of first limiting mechanisms 2 is equal to the number of the plurality of second limiting mechanisms 3, and the plurality of first limiting mechanisms 2 and the plurality of second limiting mechanisms 3 are alternately arranged on a circumferential direction 43 of the disc body 1 in order to achieve a balanced performance.

The two ends of the rivet 21 are clamped against the disc body 1 with a first pressing force, and the first screw unit 34 and the second screw unit 35 are clamped against the disc body 1 with a second pressing force; wherein the first pressing force is different from the second pressing force, so that the floating margin, connection strength, and restraint force of the outer disc 12 relative to the inner disc 11 at different positions will also be different, and can be more adjustable and variable instead of providing only a single monotonous performance at all angles.

In other words, the inner disc 11 and the outer disc 12 are compositely connected through a plurality of first limiting mechanisms 2 and a plurality of second limiting mechanisms 3 of different types to achieve composite functions. For example, but not limited to, the structure of each first limiting mechanism 2 is relatively simple, and has the advantages of quick assembly and low cost; and each second limiting mechanism 3 provides a relative floating margin between the outer disc 12 and the inner disc 11 that can be freely adjusted, so that the brake disc can have two different advantages to better meet user needs.
