Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, specifically to a heavy-duty vehicle brake disc with irregularly shaped heat dissipation fins. Background Technology

[0002] A brake disc (also known as a brake pad) is a rotating friction couple in a disc brake system. It is typically a metal disc structure that rotates synchronously with the wheel. During braking, fixed components (such as calipers) clamp the two end faces of the brake disc, converting kinetic energy into heat energy through friction, thereby slowing the vehicle down or stopping it. Heavy-duty trucks, construction machinery, and other heavy-duty vehicles generate a large amount of heat during frequent braking. If the heat dissipation efficiency is insufficient, it can easily lead to localized high temperatures, thermal stress concentration, and even cracking of the disc, seriously affecting braking safety. Traditional brake discs typically employ a uniformly distributed straight or arc-shaped heat dissipation fin structure, using the centrifugal force generated by rotation to guide airflow for heat dissipation, or perforations are drilled on the disc surface to improve heat dissipation.

[0003] However, increasing the number of cooling fins on existing brake discs leads to an increase in the weight and material usage of the disc. While drilling through the disc surface can improve heat dissipation, it also makes the brake disc prone to cracking, significantly impacting its overall strength and durability. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heavy-duty vehicle brake disc with irregularly shaped heat dissipation ribs. By rotating and cutting one end of the airflow guide of the heat dissipation rib three, the airflow entering the heat dissipation duct is increased, improving the heat dissipation efficiency of the brake disc. The first ventilation hole is connected by a pair of horizontal blocks, and the second ventilation hole is connected by a second horizontal block. On the one hand, the heat of the brake disc is carried away by the ventilation holes, improving the heat dissipation efficiency of the brake disc. On the other hand, the impact of drilling on the strength of the brake disc is reduced, resulting in a brake disc with higher structural strength, greater durability, and better heat dissipation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heavy-duty vehicle brake disc with irregularly shaped heat dissipation ribs, including a disc 1 and a disc 2 connected to each other, and a heat dissipation rib 1 arranged in a ring array between the disc 1 and the disc 2. A heat dissipation air duct is formed between two adjacent heat dissipation rib 1s. A heat dissipation rib 3 and a heat dissipation rib 2 are arranged sequentially from the air inlet to the air outlet in the heat dissipation air duct. One end of the heat dissipation rib 3 is provided with a guide portion to guide airflow into the heat dissipation air duct. A horizontal baffle 2 is provided at the end of the heat dissipation rib 2 near the air outlet, and a horizontal baffle 1 is provided at the end of the heat dissipation rib 1 near the air inlet. The horizontal baffle 1 and the horizontal baffle 2 are arranged alternately.

[0006] Both the first and second discs are provided with a plurality of ventilation holes. The ventilation holes are connected to the heat dissipation duct. The ventilation holes correspond to the positions of the horizontal blocks on the heat dissipation fins. The diameter of the ventilation holes is smaller than the length of the horizontal blocks.

[0007] Both the first and second discs are provided with a plurality of ventilation holes 2 arranged in an array. The ventilation holes 2 are connected to the heat dissipation duct. The ventilation holes 2 correspond to the positions of the horizontal blocks 2 on the heat dissipation fins 2. The diameter of the ventilation holes 2 is smaller than the length of the horizontal blocks 2.

[0008] Both the first and second discs have scribbles on their outer surfaces. One end of each scribbles is located at the corresponding position at the other end of the first heat dissipation fin, and the other end of each scribbles is located at the corresponding position at the other end of the second heat dissipation fin.

[0009] One end of the scribed line is provided with a spherical groove, the depth of which is greater than the depth of the scribed line.

[0010] The cross-sectional area of ​​the other end of the third heat dissipation fin is greater than the cross-sectional area of ​​the other end of the second heat dissipation fin.

[0011] Both the first and second discs are provided with ventilation holes three, which are respectively located on both sides of the first heat dissipation fin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By rotating and cutting one end of the heat dissipation rib three, the airflow is drawn into the heat dissipation duct, making the airflow into the heat dissipation duct larger. The airflow entering the heat dissipation duct is cut by heat dissipation rib one and heat dissipation rib two respectively. The airflow carries away the heat in the heat dissipation duct and cools the heat dissipation duct. The airflow between heat dissipation rib one and heat dissipation rib two then passes through the shielding of the horizontal block two and the horizontal block one in sequence to form turbulence. The airflow is fully mixed and heat exchanged, thereby improving the heat dissipation efficiency of the brake disc.

[0014] (2) The first ventilation hole is connected by the first cross block and the second ventilation hole is connected by the second cross block. Some airflow is discharged through the first and second ventilation holes. On the one hand, it takes away the heat of the brake disc and improves the heat dissipation efficiency of the brake disc. On the other hand, it reduces the impact of drilling on the strength of the brake disc. The brake disc has higher structural strength and better heat dissipation effect.

[0015] (3) By setting scribbles on the outer surfaces of disc one and disc two, and setting a spherical groove at one end of the scribbles, the depth of the spherical groove is greater than the depth of the scribbles. On the one hand, the airflow is guided to flow along a specific path, which further improves the heat dissipation effect. On the other hand, the stress is dispersed by the spherical groove, which prevents the generation and expansion of scribbles cracks, and further improves the heat dissipation effect and durability of the brake disc.

[0022] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] See Figures 1-5 A heavy-duty vehicle brake disc with irregularly shaped heat dissipation ribs includes a disc 1 and a disc 2 connected to each other, and a heat dissipation rib 3 arranged in a ring array between the disc 1 and the disc 2. A heat dissipation duct 4 is formed between two adjacent heat dissipation ribs 3. Heat dissipation ribs 3 6 and 2 5 are arranged sequentially from the air inlet to the air outlet in the heat dissipation duct 4. One end of the heat dissipation rib 3 6 is provided with a guide part 61 to guide airflow into the heat dissipation duct 4. Specifically, the guide part 61 is designed in the shape of a fan blade. The rotation of the guide part 61 draws in more airflow into the heat dissipation duct 4. A horizontal baffle 2 51 is provided at the end of the heat dissipation rib 2 5 near the air outlet, and a horizontal baffle 31 is provided at the end of the heat dissipation rib 3 near the air inlet. The horizontal baffles 31 and 2 51 are arranged alternately.

[0024] Both disc 1 and disc 2 are provided with a number of ventilation holes 7. The ventilation holes 7 are connected to the heat dissipation duct 4. The ventilation holes 7 correspond to the positions of the horizontal blocks 31 on the heat dissipation fins 3. The diameter of the ventilation holes 7 is smaller than the length of the horizontal blocks 31. The ventilation holes 7 are connected by the horizontal blocks 31.

[0025] Both disc 1 and disc 2 are provided with a number of ventilation holes 2 8. The ventilation holes 2 8 are connected to the heat dissipation duct 4. The ventilation holes 2 8 correspond to the positions of the horizontal blocks 2 51 on the heat dissipation fins 2 5. The diameter of the ventilation holes 2 8 is smaller than the length of the horizontal blocks 2 51.

[0026] Both disc 1 and disc 2 have scribbles 9 on their outer surfaces. One end of the scribbles 9 is located at the corresponding position at the other end of the heat dissipation rib 3, and the other end of the scribbles 9 is located at the corresponding position at the other end of the heat dissipation rib 5. By adjusting the thickness of the heat dissipation rib 3 and the heat dissipation rib 5, the impact of the scribbles 9 on the strength of the disc surface is reduced. The two ends of the scribbles 9 are stronger. The scribbles 9 are used to increase heat dissipation and collect dust on the disc surface, thereby improving the braking effect.

[0027] One end of the scribing line 9 is provided with a spherical groove 91. The depth of the spherical groove 91 is greater than the depth of the scribing line 9. By setting the spherical groove 91, on the one hand, it is to prevent the scribing line 9 from cracking and causing damage to the disc surface. On the other hand, it is to collect excess dust from the scribing line 9 and improve the braking effect.

[0028] The cross-sectional area of ​​the other end of heat dissipation fin 3 6 is greater than the cross-sectional area of ​​the other end of heat dissipation fin 2 5.

[0029] Both disc 1 and disc 2 are provided with ventilation holes 3 10, which are located on both sides of heat dissipation fin 3.

[0030] The specific working process and principle of this utility model:

[0031] When the brake disc rotates synchronously with the vehicle, the rotational cutting of the airflow at one end of the airflow guide 61 of the heat dissipation rib 3 6 creates a pressure difference, drawing the airflow into the heat dissipation duct 4. The airflow guide 61 is designed in a fan blade shape, making the airflow entering the heat dissipation duct 4 larger. The airflow entering the heat dissipation duct 4 is cut by the heat dissipation rib 1 3 and the heat dissipation rib 2 5 respectively, and the airflow carries away the heat in the heat dissipation duct 4, cooling the heat dissipation duct 4. The airflow between the heat dissipation rib 1 3 and the heat dissipation rib 2 5 then passes through the obstruction of the cross block 2 51 and the cross block 1 31 in sequence to form turbulence. The airflow is fully mixed and heat exchanged, thereby improving the heat dissipation efficiency of the brake disc.

[0032] Ventilation hole 7 is located at the corresponding position of crossbar block 31, and ventilation hole 8 is located at the corresponding position of crossbar block 51. The diameter of ventilation hole 7 is smaller than the length of crossbar block 31, and the diameter of ventilation hole 8 is smaller than the length of crossbar block 51. Ventilation hole 7 is connected to crossbar block 31, and ventilation hole 8 is connected to crossbar block 51. Part of the airflow is discharged through ventilation hole 7 and ventilation hole 8. On the one hand, it carries away the heat of the brake disc and improves the heat dissipation efficiency of the brake disc. On the other hand, the connection between crossbar block 31 and crossbar block 51 reduces the impact of drilling on the strength of the brake disc, resulting in higher structural strength and better heat dissipation of the brake disc.

[0033] By providing scribing lines 9 on the outer surfaces of both disc 1 and disc 2, and providing a spherical groove 91 at one end of the scribing lines 9, the depth of the spherical groove 91 is greater than the depth of the scribing lines 9. On the one hand, it guides the airflow along a specific path, further improving the heat dissipation effect and scraping away dust from the surface of the brake disc. On the other hand, the spherical groove 91 disperses stress, preventing the generation and propagation of cracks in the scribing lines 9, further improving the heat dissipation effect and durability of the brake disc.

[0034] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
