Description

Brake Disc

The present invention relates to brake discs.

The purpose of braking is achieved by generating braking force by clamping the brake disc with a caliper to generate friction. 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, which makes the connection between the inner and outer discs 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 problems.

The main purpose of the present invention is to provide a brake disc that uses a composite different limiting mechanism to effectively and stably limit the inner disc and outer disc in the axial direction and produce a composite effect.

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 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 plug-in portion, a second plug-in portion, a plurality of baffles and a plurality of rivets, the first plug-in portion is arranged on the outer disc, the second plug-in portion is arranged on the inner disc, the plurality of baffles are respectively arranged on two opposite sides of the disc body, and the plurality of rivets are penetrated along the axial direction to rivet the plurality of baffles and the disc body; the at least one second limiting mechanism includes A first concave hole portion, a second concave hole portion, a first 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 concave opening of the first concave hole portion and the concave opening of the second concave hole portion are connected to each other face to face in the radial direction, and the first concave hole portion and the second concave hole portion enclose a set of connection holes, at least one of the first screw connection unit and the second screw connection unit is penetrated through the set of connection holes and screwed to each other, and a first stop portion of the first screw connection unit interferes with the disc main body in the axial direction.

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

Please refer to Figures 1 to 6, 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, and includes an inner disc 11 and an outer disc 12, wherein the outer disc 12 surrounds the inner disc 11.

The at least one first limiting mechanism 2 includes a first plug-in portion 21, a second plug-in portion 22, a plurality of baffles 23 and a plurality of rivets 24. The first plug-in portion 21 is arranged on the outer disc 12, and the second plug-in portion 22 is arranged on the inner disc 11. The plurality of baffles 23 are respectively arranged on two opposite sides of the disc main body 1 to clamp the first plug-in portion 21 and the second plug-in portion 22. The plurality of rivets 24 are penetrated along the axial direction 41 to rivet the plurality of baffles 23 and the disc main body 1. It can be understood that the first plug-in portion 21 and the second plug-in portion 22 can move relative to each other in the space defined by the plurality of baffles 23 to achieve the purpose of floating the outer disc 12 relative to the inner disc 11. In this embodiment, the first plug-in portion 21 and the second plug-in portion 22 are configured in a concave-convex plug-in manner in the radial direction 42 to increase the limit position other than the axial direction 41 and thus improve the connection stability.

The at least one second limiting mechanism 3 includes a first concave hole portion 31, a second concave hole portion 32, a first screw connection unit 34 and a second screw connection unit 35. The first concave hole portion 31 is provided on the outer disc 12, and the second concave hole portion 32 is provided on the inner disc 11. The concave opening of the first concave hole portion 31 and the concave opening of the second concave hole portion 32 are connected to each other face to face in the radial direction 42, and the first concave hole portion 31 and the second concave hole portion 32 form a set of connection holes 33. At least one of the first screw connection unit 34 and the second screw connection unit 35 penetrates the set of connection holes 33 and is screwed to each other. A first blocking portion 341 of the first screw connection unit 34 interferes with the disc main body 1 in the axial direction 41. In this embodiment, the first screw connection unit 34 is rotatably screwed to the second screw connection unit 35. The user can adjust the force of the first screw connection unit 34 and the second screw connection unit 35 clamping the disc main body 1 in the axial direction 41 after being screwed together according to the needs, thereby changing the margin of the partial floating of the outer disc 12 relative to the inner disc 11.

It is worth mentioning that the plurality of rivets 24 force the plurality of baffles 23 to clamp against the disc body 1 with a first clamping force, and the first screw unit 34 and the second screw unit 35 to clamp against the disc body 1 with a second clamping force; wherein the first clamping force is different from the second clamping 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 the at least one first limiting mechanism 2 and the at least one second limiting mechanism 3 of different types to achieve composite functions. For example, but not limited to, the at least one first limiting mechanism 2 provides a more stable connection between the outer disc 12 and the inner disc 11, and the at least one second limiting mechanism 3 provides the outer disc 12 and the inner disc 11 with a relative floating margin that can be freely adjusted, so that the brake disc can have two different advantages to better meet the needs of users.

Furthermore, there are plural first limiting mechanisms 2, and the plural first limiting mechanisms 2 are arranged along a circumferential direction 43 of the disc main body 1. A rivet 241 of a plurality of rivets 24 of a first limiting mechanism 2 and a rivet 241 of a plurality of rivets 24 of another adjacent first limiting mechanism 2 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. Specifically, the plurality of first limiting mechanisms 2 are arranged at interval angles (e.g., at equal intervals) so that their center of gravity is located on an axis line 5 of the disc body 1, so that the entire brake disc can rotate stably.

It is worth mentioning that the plurality of riveting members 24 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 so that the position of the center of gravity in the radial direction 42 can fall on the axial line 5. 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 making the brake disc rotate more stably is achieved.

Similarly, the number of the at least one second limiting mechanism 3 is plural, and the plural second limiting mechanisms 3 are arranged along the circumferential direction 43 of the disc main body 1, and the first stop 341 of the first screw connection unit 34 of one second limiting mechanism 3 and the first stop 341 of the first screw connection unit 34 of another adjacent second limiting mechanism 3 are respectively located at two opposite sides of the disc main body 1 to evenly distribute the weight of the disc main body 1 on the two sides in the axial direction 41. In addition, the plural second limiting mechanisms 3 are also arranged at interval angles so that their center of gravity is located on the axial line 5 of the disc main body 1 (such as equi-angle interval arrangement). As can be seen from the above, the plurality of first limiting mechanisms 2 and the plurality of second limiting mechanisms 3 all adopt the same layout configuration, so when the plurality of second limiting mechanisms 3 and the plurality of first limiting mechanisms 2 are directly and simultaneously superimposed on the disc body 1, the overall rotation performance can be maintained stably.

In this embodiment, 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 total number of the plurality of first limiting mechanisms 2 and the plurality of second limiting mechanisms 3 is an even number. The plurality of first limiting mechanisms 2 and the plurality of second limiting mechanisms 3 are alternately arranged in the circumferential direction 43 of the disc main body 1, in order to achieve a balanced performance.

A second stopper 351 of the second screw connection unit 35 interferes with the disc main body 1 in the axial direction 41. The disc main body 1 is between the first stopper 341 and the second stopper 351. Each second limiting mechanism 3 further includes an elastic member 36 (such as a spiral spring). 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 stopper 341 and the second stopper 351. By different compression degrees of the elastic member 36, the floating ability of the outer disc 12 relative to the inner disc 11 can be changed.

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 disk 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 disturbed or damaged by foreign objects.

Similarly, in order to balance the weight of the disk body 1 on two opposite sides in the axial direction, 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 on two opposite sides of the disk body 1.
