Abstract

The utility model discloses a quick heat dissipation structure of a brake disc, which comprises a first disc body and a second disc body, a plurality of ribs are fixed on one side, close to the second disc body, of the first disc body, and the ribs are annularly arrayed between the first disc body and the second disc body at equal intervals. A fixing piece used for fixing the second disc body and the first disc body is arranged in the second disc body, a plurality of heat dissipation holes are formed in the first disc body and the second disc body, and a gap between the first disc body and the second disc body is divided into a plurality of cavities through the ribs. Due to the fact that the distance between the two arc-shaped heat dissipation fins in the same cavity is gradually reduced in the direction from the first disc body outer ring to the first disc body inner ring, when air is blown in the cavity, due to the fact that the space between the two arc-shaped heat dissipation fins is narrower and narrower, the air speed is increased, and the heat dissipation efficiency is improved. And therefore, the amount of air flowing through the surfaces of the arc-shaped heat dissipation fins and the rectangular heat dissipation fins in unit time is increased, and more air flow can take away more heat more quickly, so that the heat dissipation speed is accelerated.

Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, and in particular to a rapid heat dissipation structure for brake discs. Background Technology

[0002] The edge of the car brake disc is equipped with a hydraulic clamping device. When braking, the friction pads in the clamping device are clamped to the brake disc by the hydraulic system. The brake disc decelerates quickly under the action of friction. The huge kinetic energy of the car needs to be dissipated in a short time, and this dissipation is mainly reflected in the frictional heat of the brake disc. Therefore, the heat dissipation of the brake disc is particularly important.

[0003] Publication No. CN 222296813 U discloses a split-type heat-dissipating brake disc, including a first disc body and a second disc body. Multiple support blocks are fixedly arranged between the first disc body and the second disc body. Multiple blocking brackets are fixedly arranged on the first disc body. A brake disc hub is fixedly arranged on the side of the first disc body away from the second disc body. Multiple rows of heat dissipation holes and multiple through slots are provided on the surfaces of the first disc body and the second disc body. There are twelve rows of heat dissipation holes, and the number of heat dissipation holes in each row is three. There are five through slots, and the through slots are arranged in a ring-shaped equidistant array on the first disc body and the second disc body.

[0004] The aforementioned existing technologies mainly improve heat dissipation by increasing air convection. Although the heat dissipation effect is improved, the heat dissipation method is singular, and the heat dissipation area is still only the area of ​​the two discs, which sometimes results in the brake discs not being able to dissipate heat effectively. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] In view of this, the purpose of this utility model is to propose a rapid heat dissipation structure for brake discs. Existing brake discs improve heat dissipation by increasing air convection. Although the heat dissipation effect is improved, the heat dissipation method is singular, and the heat dissipation area is still only the area of ​​the two discs, which sometimes results in unsatisfactory heat dissipation effect of the brake disc.

[0007] (II) Technical Solution

[0008] To achieve the above technical objectives, this utility model provides a rapid heat dissipation structure for brake discs:

[0009] It includes a first disk and a second disk. Multiple ribs are fixed to the side of the first disk near the second disk. These ribs are arranged in a ring-shaped, equidistant array between the first and second disks. A fixing member is provided inside the second disk to secure the second disk and the first disk. Multiple heat dissipation holes are provided inside both the first and second disks. The multiple ribs divide the gap between the first and second disks into multiple chambers. Each chamber contains two sets of primary heat dissipation components and one set of secondary heat dissipation components. The primary heat dissipation component includes two arc-shaped heat-conducting plates, with arc-shaped heat dissipation fins fixed to the side of the two arc-shaped heat-conducting plates that are close to each other. The secondary heat dissipation component includes two triangular heat-conducting plates, with multiple rectangular heat dissipation fins fixed at equal intervals on the side of the two triangular heat-conducting plates that are close to each other. The secondary heat dissipation component is located between the two primary heat dissipation components.

[0010] Preferably, the distance between the two arc-shaped heat dissipation fins in the primary heat dissipation component gradually decreases from the outer ring of the first disk to the inner ring of the first disk.

[0011] Preferably, one side of the first plate has a plurality of first triangular grooves and a plurality of first arc-shaped grooves, and one side of the second plate has a plurality of second triangular grooves and a plurality of second arc-shaped grooves. The arc-shaped heat-conducting plate can be embedded in the first arc-shaped grooves and the second arc-shaped grooves, and the triangular heat-conducting plate can be embedded in the first triangular grooves and the second triangular grooves.

[0012] Preferably, the fastener includes multiple countersunk holes formed in the body of the second disc, with bolts passing through the countersunk holes, and multiple threaded holes formed in the rib, with the bolts and threaded holes being threadedly connected.

[0013] Preferably, a shaft head is fixed on one side of the first disc body, and multiple mounting holes are equally spaced inside the shaft head.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. When the car brakes, air enters the chamber through the gap between the first and second discs, which helps to dissipate heat. Air can also enter the chamber through the heat dissipation holes, which creates air convection and further improves the heat dissipation effect. The arc-shaped heat dissipation fins, arc-shaped heat-conducting plates, triangular heat-conducting plates, and rectangular heat dissipation fins can absorb the heat generated by the friction between the first and second discs. The arc-shaped heat dissipation fins, arc-shaped heat-conducting plates, triangular heat-conducting plates, and rectangular heat dissipation fins increase the heat dissipation area, thereby improving the heat dissipation effect.

[0016] 2: As the distance between the two arc-shaped heat dissipation fins in the same chamber gradually decreases from the outer ring of the first plate to the inner ring of the first plate, the air speed increases when the air is blown in the chamber because the space between the two arc-shaped heat dissipation fins becomes narrower. When the air speed increases, the amount of air flowing through the surface of the arc-shaped and rectangular heat dissipation fins per unit time increases. More air flow can carry away more heat more quickly, thereby accelerating the heat dissipation speed. Attached Figure Description

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Reference Figure 1-5 :

[0026] In one embodiment of this utility model, a rapid heat dissipation structure for a brake disc is provided, including a first disc body 1 and a second disc body 2. Multiple ribs 3 are fixed to the side of the first disc body 1 near the second disc body 2, arranged in a ring-shaped equidistant array between the first disc body 1 and the second disc body 2. A fixing member is provided inside the second disc body 2 to fix the second disc body 2 and the first disc body 1. Multiple heat dissipation holes 18 are provided inside both the first disc body 1 and the second disc body 2. The multiple ribs 3 divide the gap between the first disc body 1 and the second disc body 2 into multiple chambers 4, and each chamber 4 is provided with two sets of primary heat dissipation components and one set of secondary heat dissipation components. The primary heat dissipation component includes two arc-shaped heat-conducting plates 6, with arc-shaped heat dissipation fins 5 fixed together on the side of the two arc-shaped heat-conducting plates 6 that are close to each other. The secondary heat dissipation component includes two triangular heat-conducting plates 7, with multiple rectangular heat dissipation fins 8 fixed at equal intervals on the side of the two triangular heat-conducting plates 7 that are close to each other. The secondary heat dissipation component is located between the two primary heat dissipation components.

[0027] The fasteners include multiple countersunk holes 9 opened in the second disc body 2, with bolts 11 passing through the countersunk holes 9. Multiple screw holes 10 are opened in the rib 3, and the bolts 11 and screw holes 10 are threadedly connected. A shaft head 16 is fixed on one side of the first disc body 1, and multiple mounting holes 17 are opened at equal intervals in the shaft head 16.

[0028] During installation, first, invert the first disc 1 so that the shaft head 16 faces down and the first disc 1 faces up. Then, place the arc-shaped heat-conducting plate 6 into the corresponding first arc-shaped groove 13, and then place the triangular heat-conducting plate 7 into the corresponding first triangular groove 12. Then, cover the second disc 2 so that the other arc-shaped heat-conducting plate 6 and the other triangular heat-conducting plate 7 are embedded into the corresponding second arc-shaped groove 15 and second triangular groove 14. Then, put the bolt 11 into the countersunk hole 9 and then thread the bolt 11 and the screw hole 10 to fix the second disc 2 and the rib 3 together, that is, fix the second disc 2 and the first disc 1 together.

[0029] In addition, the distance between the two arc-shaped heat dissipation fins 5 in the primary heat dissipation component gradually decreases from the outer ring of the first plate 1 to the inner ring of the first plate 1. A plurality of first triangular grooves 12 and a plurality of first arc-shaped grooves 13 are provided on one side of the first plate 1, and a plurality of second triangular grooves 14 and a plurality of second arc-shaped grooves 15 are provided on one side of the second plate 2. The arc-shaped heat-conducting plate 6 can be embedded in the first arc-shaped grooves 13 and the second arc-shaped grooves 15, and the triangular heat-conducting plate 7 can be embedded in the first triangular grooves 12 and the second triangular grooves 14.

[0030] When the car brakes, air enters the chamber 4 through the gap between the first disc 1 and the second disc 2, which helps to dissipate heat. Air can also enter the chamber 4 through the heat dissipation holes 18, creating air convection and further enhancing the heat dissipation effect. The arc-shaped heat dissipation fins 5, arc-shaped heat-conducting plates 6, triangular heat-conducting plates 7, and rectangular heat dissipation fins 8 absorb the heat generated by friction between the first disc 1 and the second disc 2. These components increase the heat dissipation area, thus improving the cooling effect. Furthermore, because the distance between the two arc-shaped heat dissipation fins 5 within the same chamber 4 gradually decreases from the outer ring of the first disc 1 towards the inner ring, the airflow within the chamber 4 increases as the space between the two arc-shaped heat dissipation fins narrows. This increased airflow per unit time allows more air to pass over the surfaces of the arc-shaped heat dissipation fins 5 and rectangular heat dissipation fins 8, resulting in faster heat dissipation and accelerating the cooling process.

[0031] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
