Description

Technical Field

[0001] This utility model belongs to the field of brake disc technology, specifically relating to a high-efficiency heat dissipation brake disc. Background Technology

[0002] The brake disc is the friction component of a disc brake and is one of the most important components related to vehicle safety. In addition to having the strength and rigidity required of a component, it should also have the highest and most stable coefficient of friction, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity, otherwise it is easily damaged and fails.

[0003] Brake disc cracking is the primary cause of brake disc failure, and one reason for this cracking is that the brake disc remains at a high temperature for extended periods without adequate heat dissipation. Taking heavy-duty trucks as an example, the harsh operating conditions of heavy-duty trucks easily cause the brake discs to heat up rapidly during braking. Improper use, such as overloading or sudden cooling, can lead to brake disc cracking. Traditional methods to improve brake disc heat dissipation typically involve increasing the number and volume of cooling fins, but this increases the weight of the brake disc, contradicting the goal of lightweight brake discs. Therefore, a new type of brake disc with more efficient heat dissipation is needed, and this invention addresses this technical problem. Utility Model Content

[0004] This invention provides a high-efficiency heat dissipation brake disc that can achieve heat dissipation through multiple methods, making the heat dissipation of the brake disc more efficient, and reducing the weight of the brake disc compared with traditional methods.

[0005] A high-efficiency heat dissipation brake disc includes a brake disc one, a heat dissipation mechanism one connected to the end face of the brake disc one, a heat dissipation mechanism two connected to the heat dissipation mechanism one, a heat dissipation mechanism three connected to the end face of the brake disc one, a brake disc two connected to the heat dissipation mechanism one and the heat dissipation mechanism three, and a disc neck connected to the brake disc two; the heat dissipation mechanism one and the heat dissipation mechanism two are used to form an air duct, and the heat dissipation mechanism three is used to absorb the heat of the brake disc one and the brake disc two and dissipate it.

[0006] Furthermore, the heat dissipation mechanism one includes a plurality of heat dissipation ribs one and a plurality of heat dissipation ribs two connected to the brake disc one. The plurality of heat dissipation ribs one are respectively connected to the heat dissipation mechanism two, and the heat dissipation ribs one and the heat dissipation ribs two are respectively connected to the brake disc two.

[0007] Furthermore, the positions of two adjacent heat dissipation fins (first and second) are staggered.

[0008] Furthermore, the second heat dissipation mechanism includes a plurality of bosses connected to the first brake disc, and the plurality of bosses are respectively connected to the plurality of the second heat dissipation fins.

[0009] Furthermore, the boss is connected between two adjacent heat dissipation fins and between adjacent heat dissipation fins.

[0010] Furthermore, the boss has a through groove for ventilation inside, with both ends of the through groove located on the side of the boss.

[0011] Furthermore, the height of the boss is lower than the height of the second heat dissipation fin.

[0012] Furthermore, the heat dissipation mechanism three includes a heat-absorbing seat one connected to the brake disc one, a heat-conducting copper column with one end connected to the heat-absorbing seat one, a heat-absorbing seat two connected to the other end of the heat-conducting copper column, and a heat sink connected to the heat-conducting copper column. The heat-absorbing seat two is connected to the brake disc two.

[0013] The technical effects of this utility model are as follows: (1) Compared with the traditional method, the heat dissipation method of this application does not simply increase the number and volume of heat dissipation fins, but adopts a variety of heat dissipation mechanisms to achieve a variety of heat dissipation methods. Heat dissipation is achieved through the air duct formed by heat dissipation mechanism one and heat dissipation mechanism two, and heat dissipation mechanism three can absorb the heat of brake disc one and brake disc two and dissipate it. Thus, through the cooperation of multiple heat dissipation mechanisms, the function of efficient heat dissipation is achieved. (2) The heat dissipation ribs 1 and 2 in this scheme can form a duct to facilitate the flow of air. The boss can occupy the space between two adjacent heat dissipation ribs 1 and the space between heat dissipation ribs 1 and 2, thereby narrowing the duct and accelerating the flow of air in the duct, thereby increasing the convective heat transfer coefficient of the duct section, reducing the temperature of the brake disc, and thus reducing the risk of brake disc cracking. (3) The heat dissipation mechanism three in this scheme can absorb the heat of brake disc one and brake disc two through heat absorption seat one and heat absorption seat two, and transfer the heat to the heat sink through the heat-conducting copper column, and carry away the heat on the heat sink through the flowing air, thereby realizing the heat dissipation function. (4) When air flows in the through groove, it can carry away the heat from the heat dissipation fins and the inside of the boss, and in this way, the weight of the brake disc can be reduced, further achieving lightweighting.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments and accompanying drawings.

[0021] A high-efficiency heat dissipation brake disc includes a brake disc 1, a heat dissipation mechanism 1 connected to the end face of the brake disc 1, a heat dissipation mechanism 2 connected to the heat dissipation mechanism 1, a heat dissipation mechanism 3 connected to the end face of the brake disc 1, a brake disc 2 connected to the heat dissipation mechanism 1 and the heat dissipation mechanism 3, and a disc neck 3 connected to the brake disc 2; the heat dissipation mechanism 1 and the heat dissipation mechanism 2 are used to form air ducts, and the heat dissipation mechanism 3 is used to absorb the heat of the brake disc 1 and the brake disc 2 and dissipate it.

[0022] Furthermore, the heat dissipation mechanism one includes several heat dissipation ribs one 4 and several heat dissipation ribs two 6 connected to the brake disc one 1. The heat dissipation ribs one 4 are respectively connected to the heat dissipation mechanism two, and the heat dissipation ribs one 4 and the heat dissipation ribs two 6 are respectively connected to the brake disc two 2.

[0023] Furthermore, the positions of two adjacent heat dissipation fins 1 (4) and two adjacent heat dissipation fins 2 (6) are staggered.

[0024] Furthermore, the second heat dissipation mechanism includes several bosses 5 connected to the brake disc 1, and each boss 5 is connected to a number of heat dissipation ribs 6. In this embodiment, the sides of the bosses 5 are curved. Compared to a flat surface, a curved surface has a larger contact area with the air, which is beneficial for heat dissipation. In this embodiment, two sets of heat dissipation ribs 6 are provided. For ease of observation, only one set of heat dissipation ribs 6 is connected to the bosses 5. Workers can set different numbers of heat dissipation ribs 4, heat dissipation ribs 6, and bosses 5 during production according to actual needs. This is something that those skilled in the art can easily conceive of, and will not be described in detail here.

[0025] Furthermore, the boss 5 is connected between two adjacent heat dissipation fins 4, and also between adjacent heat dissipation fins 4 and 6. This reduces the width of the air duct, which helps to increase the air velocity. Since the higher the fluid velocity, the higher the convective heat transfer coefficient, it is more conducive to heat dissipation.

[0026] Furthermore, the interior of the boss 5 is provided with a through groove 10 for ventilation, with both ends of the through groove 10 respectively located on the side of the boss 5. In this embodiment, each boss 5 is provided with two through grooves 10.

[0027] Furthermore, the height of boss 5 is lower than the height of heat dissipation fin 6. Therefore, the air in the air duct can also come into contact with the top surface of boss 5, increasing the contact area with the air. Moreover, compared with heat dissipation fins, this structure of boss 5 can save materials and help reduce the weight of the brake disc.

[0028] Furthermore, the heat dissipation mechanism three includes a heat-absorbing seat 9 connected to the brake disc 1, a heat-conducting copper pillar 8 connected at one end to the heat-absorbing seat 9, a heat-absorbing seat two connected to the other end of the heat-conducting copper pillar 8, and a heat sink 7 connected to the heat-conducting copper pillar 8. The heat-absorbing seat two is connected to the brake disc 2. In this embodiment, both the heat-absorbing seat 9 and the heat-absorbing seat two are nickel-plated aluminum seats. A layer of silicone grease can be applied between the nickel-plated aluminum seats and the brake disc 1 and the brake disc 2 for heat conduction. The heat sink 7 is an aluminum fin.

[0029] The working process of this utility model is as follows: When the brake disc rotates, air flows between brake disc 1 and brake disc 2. Heat absorption seat 9 and heat absorption seat 2 absorb the heat from brake disc 1 and brake disc 2, and transfer the heat to heat sink 7 through heat-conducting copper pillar 8. When the air flows, it comes into contact with heat sink 7 and carries away the heat on heat sink 7, thus achieving the heat dissipation function. When air flows in the air duct, it comes into contact with heat dissipation fin 1 4, heat dissipation fin 2 6 and boss 5 to achieve heat dissipation. Moreover, the air entering the through groove 10 will carry away the heat inside the boss 5 and heat dissipation fin 2 6. Therefore, the setting of the through groove 10 not only increases the contact area between the boss 5 and heat dissipation fin 2 6 and the air, but also reduces the material used for the boss 5 and heat dissipation fin 2 6, thereby making the brake disc lighter. Furthermore, the air blown out from the through groove 10 will continue to flow in the air duct and eventually be blown out between brake disc 1 1 and brake disc 2 2.

[0030] The technical features not described in detail in this solution are based on the conventional operation and general understanding of those skilled in the art and are derived from existing technologies, and will not be elaborated further here.

[0031] The above embodiments are merely preferred embodiments of this utility model. Those skilled in the art can obtain other embodiments from the above embodiments without creative effort. Therefore, this application protects not only the above embodiments, but also the scope consistent with the principles and features of this application.
