Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake disc technology, and in particular to a low-noise brake disc. Background Technology
[0002] A brake disc, also known as a brake caliper, is a rotating metal disc, usually made of alloy steel and fixed to the wheel. It rotates with the wheel. When the brake is applied during vehicle operation, the brake caliper clamps the brake disc, using friction to slow down or stop the vehicle.
[0003] However, in existing equipment, most brake discs sometimes emit a harsh sound when braking, resulting in a poor driving experience for drivers. Therefore, a low-noise brake disc is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-noise brake disc.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-noise brake disc, including a center drum, a first brake disc fixedly connected to one side of the center drum, a first silencing disc fixedly connected to one side of the first brake disc, a plurality of ribs fixedly connected to one side of the first silencing disc, a second silencing disc fixedly connected to one side of the plurality of ribs, and a second brake disc fixedly connected to one side of the second silencing disc.
[0006] As a further description of the above technical solution:
[0007] Each of the first and second silent disks has multiple first honeycomb holes.
[0008] As a further description of the above technical solution:
[0009] Each of the aforementioned ribs has multiple second honeycomb holes on one side.
[0010] As a further description of the above technical solution:
[0011] Multiple heat dissipation holes and heat dissipation grooves are provided on the side of the first brake disc that is far away from the second brake disc.
[0012] As a further description of the above technical solution:
[0013] A central hole is provided on one side of the central drum, and multiple connecting grooves are provided on the inner wall of the central hole.
[0014] As a further description of the above technical solution:
[0015] The central drum has multiple mounting holes on one side and a positioning hole on the other side.
[0016] As a further description of the above technical solution:
[0017] Two threaded holes are provided on one side of the central drum.
[0018] As a further description of the above technical solution:
[0019] The outer wall of the central drum is provided with an anti-rust coating.
[0020] This utility model has the following beneficial effects:
[0021] 1. Compared with the existing technology, this low-noise brake disc, by setting a first silent disc and a first honeycomb hole, etc., when braking, the sound is transmitted to the first silent disc and the second silent disc through the first brake disc and the second brake disc respectively. Then, the multiple first honeycomb holes can absorb part of the noise, reduce the noise, and help improve the driver's driving experience and driving comfort.
[0022] 2. Compared with existing technologies, this low-noise brake disc, by setting a connecting groove, can reduce the contact area with the flange protrusion, avoid rust at the connection between the center drum and the flange, and prevent the brake disc from being difficult to disassemble.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1 to 5 This utility model provides a low-noise brake disc, including a center drum 1. The outer wall of the center drum 1 is provided with an anti-rust coating, which helps to reduce the chance of rusting. Two threaded holes 103 are opened on one side of the center drum 1. By screwing a special bolt into the two threaded holes 103 and pressing the flange on the car, it is easy to quickly remove the center drum 1. Multiple mounting holes 101 are opened on one side of the center drum 1. Positioning holes 102 are opened on one side of the center drum 1. A first brake disc 2 is fixedly connected to one side of the center drum 1. A first silent disc 3 is fixedly connected to one side of the first brake disc 2. Multiple ribs 4 are fixedly connected to one side of the first silent disc 3. A second silent disc 5 is fixedly connected to one side of the multiple ribs 4. A second brake disc 6 is fixedly connected to one side of the second silent disc 5.
[0032] In order to achieve the purpose of quietness, each of the first quiet disc 3 and the second quiet disc 5 is provided with a plurality of first honeycomb holes 301. When braking, the sound is transmitted to the first quiet disc 3 and the second quiet disc 5 through the first brake disc 2 and the second brake disc 6 respectively. Then, the plurality of first honeycomb holes 301 can absorb some of the noise, reduce the noise, and help improve the driver's driving experience and driving comfort.
[0033] In order to reduce weight, multiple second honeycomb holes 401 are provided on one side of each rib 4. The multiple second honeycomb holes 401 can reduce the overall weight of the brake disc body and at the same time help to strengthen the rib 4.
[0034] In order to achieve heat dissipation, multiple heat dissipation holes 201 and heat dissipation grooves 202 are provided on the side of the first brake disc 2 and the second brake disc 6 that are far apart from each other. The multiple heat dissipation holes 201 and heat dissipation grooves 202 dissipate heat from the first brake disc 2 and the second brake disc 6, which helps to improve heat dissipation efficiency.
[0035] In order to facilitate the disassembly of the brake disc body, a center hole 104 is provided on one side of the center drum 1. Multiple connecting grooves 105 are provided on the inner side wall of the center hole 104. The connecting grooves 105 can reduce the contact area with the flange protrusion, and prevent rust at the connection between the center drum 1 and the flange, which would make it difficult to disassemble the brake disc body.
[0036] Working principle: When braking, the sound is transmitted to the first silent disc 3 and the second silent disc 5 through the first brake disc 2 and the second brake disc 6 respectively. Then, the multiple first honeycomb holes 301 can absorb some of the noise and reduce the noise, which is conducive to improving the driver's driving experience and driving comfort. The connecting groove 105 can reduce the contact area with the flange protrusion, avoid rust at the connection between the center drum 1 and the flange, and prevent the brake disc body from being difficult to disassemble.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
