Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, and in particular to a multi-fin heat dissipation enhanced automotive brake disc. Background Technology

[0002] The brake disc is a core component of a vehicle's braking system, and its performance directly affects driving safety. During braking, the heat generated by friction causes the brake disc temperature to rise sharply. If heat dissipation is uneven, the brake disc can easily warp or crack, affecting its service life. Therefore, it is necessary to design a multi-fin heat dissipation enhanced automotive brake disc.

[0003] To address this, patent CN216951404U discloses an automotive brake disc comprising a metallurgically bonded annular disc body and several friction blocks. These friction blocks axially penetrate the annular disc body and are evenly distributed circumferentially. The surfaces of the friction blocks parallel to the annular disc body form friction surfaces on both sides of the annular disc body. This automotive brake disc exhibits a strong bond between the friction blocks and the annular disc body, excellent heat dissipation, and effectively prevents heat accumulation in the disc body that could lead to thermal cracks and other safety hazards. It meets the braking performance requirements of traditional automotive brake discs during friction braking, including resistance to friction wear and fatigue.

[0004] Although the aforementioned automotive brake discs can dissipate heat through the radial channels between the friction blocks during use, the heat inside the brake disc is not easily dissipated quickly. Therefore, it is necessary to design a multi-fin heat dissipation enhanced automotive brake disc. Utility Model Content

[0005] The purpose of this invention is to provide a multi-fin heat dissipation enhanced automotive brake disc to solve the defect of existing automotive brake discs where heat inside the brake disc is not easily dissipated quickly during heat dissipation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-fin heat dissipation enhanced automotive brake disc, including a first brake disc;

[0007] A connecting block is evenly fixed to one side of the first brake disc, and a second brake disc is evenly fixed to one side of the connecting block.

[0008] A heat dissipation structure is fixed at one edge of both the first and second brake discs. The heat dissipation structure includes a connecting ring, heat dissipation fins and heat dissipation holes. The connecting ring is fixed at one edge of the first and second brake discs. Heat dissipation fins are uniformly fixed on the outer wall of the connecting ring and heat dissipation fins are uniformly opened inside the connecting ring.

[0009] Both the first and second brake discs have a reinforcing mechanism fixed on the side away from the connecting block, and a connecting seat is fixed on one side of the second brake disc.

[0010] Furthermore, the connecting blocks are evenly distributed on one side of the first brake disc and the second brake disc.

[0011] Furthermore, the heat sinks are evenly distributed on the outer wall of the connecting ring.

[0012] Furthermore, the heat dissipation holes are evenly distributed inside the connecting ring.

[0013] Furthermore, the reinforcing mechanism includes a first reinforcing rod, a second reinforcing rod, and a protective ring. The first reinforcing rod is uniformly fixed on the outer wall of the second brake disc on the side away from the connecting block. The second reinforcing rod is uniformly fixed on the outer wall of the first brake disc on the side away from the connecting block. The protective ring is fixed at the center position on one side of the first brake disc.

[0014] Furthermore, the first reinforcing rod is evenly distributed on the outer wall of the second brake disc, and the second reinforcing rod is evenly distributed on the outer wall of the first brake disc.

[0015] Furthermore, the central axis of the protective ring and the central axis of the first brake disc are collinear.

[0016] The advantages of the multi-fin heat dissipation enhanced automotive brake disc provided by this utility model are as follows:

[0017] By incorporating a heat dissipation structure, the connecting ring enhances the stability of the connection between the first and second brake discs. The heat dissipation fins are evenly distributed on the outer wall of the connecting ring, increasing the contact area between heat and air, accelerating heat dissipation, and effectively reducing high temperature accumulation during braking. The heat dissipation holes are evenly distributed inside the connecting ring, ensuring that heat is dissipated from the inside of the first and second brake discs to the outside, avoiding local overheating. This device achieves efficient heat dissipation and improves the service life of the multi-fin heat dissipation enhanced automotive brake disc.

[0018] By incorporating a reinforcing mechanism, the first and second reinforcing rods are respectively fixed to the outer walls of the second and first brake discs, forming a support network to resist the impact force during braking and prevent deformation or cracking. The protective ring is collinear with the central axis of the second brake disc, enhancing rotational balance, reducing vibration and noise, and reducing fatigue damage by dispersing stress concentration, thereby extending the service life of the first and second brake discs. This device achieves the function of facilitating the enhancement of the overall structural stability and improves the stability of the multi-fin heat dissipation reinforced automotive brake disc during use.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides a multi-fin heat dissipation enhanced automotive brake disc, including a first brake disc 1.

[0027] Reference Figures 1-5 A connecting block 2 is evenly fixed on one side of the first brake disc 1. The connecting blocks 2 are evenly distributed on one side of the first brake disc 1 and the second brake disc 3. A second brake disc 3 is evenly fixed on one side of the connecting block 2. A heat dissipation structure 4 is fixed at the edge position on one side of the first brake disc 1 and the second brake disc 3. The heat dissipation structure 4 includes a connecting ring 41, heat dissipation fins 42 and heat dissipation holes 43. The connecting ring 41 is fixed at the edge position on one side of the first brake disc 1 and the second brake disc 3. Heat dissipation fins 42 are evenly fixed on the outer wall of the connecting ring 41. Heat dissipation fins 42 are evenly distributed inside the connecting ring 41. The heat dissipation fins 42 are evenly distributed on the outer wall of the connecting ring 41. The heat dissipation holes 43 are evenly distributed inside the connecting ring 41.

[0028] The first brake disc 1 and the second brake disc 3 are fixedly connected by the connecting block 2, together forming a brake disc mechanism with good internal heat dissipation. The heat generated during braking is conducted to the heat dissipation structure 4 at the edge through the first brake disc 1 and the second brake disc 3. The heat dissipation fins 42 can increase the contact area between the connecting ring 41 and the air. The heat dissipation holes 43 form an air circulation channel to promote the discharge of internal hot air, while reducing weight and reducing the risk of thermal deformation.

[0029] Reference Figures 1-5 Both the first brake disc 1 and the second brake disc 3 have a reinforcing mechanism 5 fixed on the side away from the connecting block 2. The reinforcing mechanism 5 includes a first reinforcing rod 51, a second reinforcing rod 52, and a protective ring 53. The first reinforcing rod 51 is evenly fixed on the outer wall of the second brake disc 3 away from the connecting block 2. The second reinforcing rod 52 is evenly fixed on the outer wall of the first brake disc 1 away from the connecting block 2. The protective ring 53 is fixed at the center position on one side of the first brake disc 1. The first reinforcing rod 51 and the second reinforcing rod 52 are evenly distributed on the outer wall of the first brake disc 1. The central axis of the protective ring 53 is collinear with the central axis of the first brake disc 1. A connecting seat 6 is fixed on one side of the second brake disc 3.

[0030] During braking, the first reinforcing rod 51 and the second reinforcing rod 52 are rigidly connected to disperse the stress generated by friction, avoiding stress concentration in a single area. The protective ring 53 serves as a central reinforcing component, ensuring the dynamic balance of the first brake disc 1 when it rotates at high speed, while protecting the shaft connection from thermal expansion.
