Description

Technical Field

[0001] The present invention relates to the technical field of brake discs, and in particular to a brake disc. Background Art

[0002] When the brake disc is used in a locomotive, the brake caliper is used to clamp the brake disc to generate braking force, which plays a role in deceleration or stopping. The brake disc has a good braking effect and is easier to maintain than drum brakes. Therefore, most locomotives are currently equipped with brake discs. When braking, the brake disc uses the friction generated between itself and the brake caliper to achieve braking. Therefore, there will inevitably be temperature changes in this process. The brake disc will generate a lot of heat, and the heat will be transferred to the brake caliper through the brake disc. If the heat is not dissipated in time, long-term overheating will cause the brake caliper to age, seriously affecting the braking performance of the locomotive.

[0003] Therefore, how to improve the heat dissipation effect of the brake disc is a technical problem that technicians currently need to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a brake disc, aiming to solve the problem of poor heat dissipation effect of existing brake discs.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A brake disc is provided, comprising a brake disc body, the brake disc body having a first brake surface and a second brake surface, the brake disc body being provided with a plurality of heat dissipation holes, the heat dissipation holes penetrating the brake disc body, the heat dissipation holes being arranged obliquely along the first brake surface toward the second brake surface, and the heat dissipation holes being arranged obliquely along a direction close to the center of the brake disc body toward a direction away from the center of the brake disc body.

[0007] Optionally, the heat dissipation holes include a first heat dissipation hole and a second heat dissipation hole, the length of the first heat dissipation hole is greater than the length of the second heat dissipation hole, the first heat dissipation holes are evenly spaced along the circumference of the brake disc body, and the second heat dissipation hole is provided between two adjacent first heat dissipation holes.

[0008] Optionally, a plurality of heat dissipation grooves are provided on the edge of the brake disc body, and the plurality of heat dissipation grooves are evenly spaced along the circumference of the brake disc body, and the first brake surface is inclined toward the second brake surface.

[0009] Optionally, a mounting hole is provided in the middle of the brake disc body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The brake disc provided by the present invention has heat dissipation holes which are arranged obliquely along the first brake surface toward the second brake surface, and the heat dissipation holes are arranged obliquely along the direction close to the center of the brake disc body toward the direction away from the center of the brake disc body. It can be understood that when the vehicle is driving, the heat dissipation holes are arranged obliquely backward and outward as a whole, and after air enters from the first brake surface, it flows out from the second brake surface after passing through the heat dissipation holes. The obliquely arranged heat dissipation holes can increase the contact area between the brake disc body and the air, and can improve the heat dissipation effect of the brake disc without reducing the structural strength. In addition, the heat dissipation holes which are arranged obliquely backward and outward are adapted to the direction of vehicle driving, so that air can be discharged from the heat dissipation holes faster, further improving the heat dissipation effect of the brake disc.

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0021] Combine the following Figures 1 to 4 A brake disc according to the present invention is described.

[0022] like Figures 1 to 4 As shown, the present invention provides a brake disc, including a brake disc body 1, the brake disc body 1 having a first brake surface 2 and a second brake surface 3, the brake disc body 1 is provided with a plurality of heat dissipation holes, the heat dissipation holes penetrate the brake disc body 1, the heat dissipation holes are inclined along the first brake surface 2 toward the second brake surface 3, and the heat dissipation holes are inclined along the direction close to the center of the brake disc body 1 toward away from the center of the brake disc body 1.

[0023] For the convenience of explanation, in this embodiment, each direction is as follows Figure 1 shown.

[0024] The brake disc provided in this embodiment is mainly used for motorcycles. The first brake surface 2 is a side close to the wheel, and the second brake surface 3 is a side close to the outside of the vehicle. The brake disc body 1 in the figure rotates counterclockwise, and the heat dissipation holes are arranged at an angle along the first brake surface 2 toward the second brake surface 3. The heat dissipation holes are arranged at an angle along the direction close to the center of the brake disc body 1 toward the direction away from the center of the brake disc body 1. It can be understood that when the vehicle is driving, the heat dissipation holes are arranged backward and outwardly as a whole. After the air 8 enters from the first brake surface 2, it flows out from the second brake surface 3 after passing through the heat dissipation holes. The inclined heat dissipation holes can increase the contact area between the brake disc body and the air 8, without reducing the structural strength, but also can improve the heat dissipation effect of the brake disc. In addition, the heat dissipation holes arranged backward and outwardly are adapted to the direction of vehicle driving, so that the air 8 can be discharged from the heat dissipation holes faster, further improving the heat dissipation effect of the brake disc.

[0025] In some embodiments, the heat dissipation holes include a first heat dissipation hole 4 and a second heat dissipation hole 5. The length of the first heat dissipation hole 4 is greater than that of the second heat dissipation hole 5. The first heat dissipation holes 4 are evenly spaced along the circumference of the brake disc body 1. A second heat dissipation hole 5 is provided between two adjacent first heat dissipation holes 4, which can reduce airflow interference and improve heat dissipation effect.

[0026] In some embodiments, a plurality of heat dissipation grooves 6 are provided on the edge of the brake disc body 1, and the plurality of heat dissipation grooves 6 are evenly spaced along the circumference of the brake disc body 1, and the first brake surface 2 is inclined toward the second brake surface 3. By providing the inclined heat dissipation grooves 6, the contact area between the brake disc body and the air 8 can be increased, and the heat dissipation effect of the brake disc can be improved without reducing the structural strength.

[0027] In some embodiments, a mounting hole 7 is provided in the middle of the brake disc body 1 for easy installation.

[0028] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
