Description

Technical Field

[0001] This utility model relates to the field of automotive brake disc technology, specifically a ventilated automotive brake disc. Background Technology

[0002] In automotive braking systems, the brake disc is a key component, and its performance directly affects vehicle safety. When braking occurs during vehicle operation, intense friction occurs between the brake pads and the brake disc, generating a large amount of heat and causing the brake disc temperature to rise rapidly. If the brake disc does not dissipate heat in time, high temperature will reduce its mechanical properties and cause thermal fade, which manifests as weakened braking effect and longer braking distance. In severe cases, it may even lead to brake failure, posing a great threat to the life safety of drivers and passengers. Currently, some brake discs on the market do not have ventilation and heat dissipation effects, and although some brake discs have taken ventilation and heat dissipation requirements into account in their structural design, the ventilation channel design of some products is not reasonable enough, and the air flow path is not smooth, resulting in low heat dissipation efficiency and difficulty in meeting the heat dissipation requirements of vehicles under complex road conditions. Therefore, a ventilated automotive brake disc needs to be designed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a ventilated automotive brake disc to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a ventilated automotive brake disc, comprising a first connecting disc, wherein a ventilation mechanism is provided around the first connecting disc, and a connecting mechanism is provided on the rear side of the ventilation mechanism; The ventilation mechanism includes a first brake disc, which is fixedly connected to the periphery of a first connecting disc. A fixing block is fixedly connected to the rear side of the first brake disc, and a connecting block is slidably connected inside the fixing block. A second brake disc is fixedly connected to the rear side of the connecting block, a blocking block is fixedly connected to the front side of the second brake disc, and a second connecting disc is fixedly connected to the inner side of the second brake disc.

[0005] Preferably, the fixing block and the connecting block are internally connected and have ventilation holes, and the two sets of ventilation holes correspond to each other, so that external air can enter between the first brake disc and the second brake disc through the fixing block and the connecting block.

[0006] Preferably, the first brake disc and the second brake disc are respectively provided with first air inlets, and both sets of first air inlets are arc-shaped. The two sets of first air inlets are respectively connected to the interior of the fixed block and the connecting block, so as to facilitate the entry of outside air through the first air inlets.

[0007] Preferably, the first brake disc and the second brake disc are respectively provided with second air inlets, and both sets of second air inlets are circular, so as to further improve the cooling effect of the first brake disc and the second brake disc through the second air inlets.

[0008] Preferably, the front side of the blocking block is fixedly connected to the rear side of the first brake disc, and the blocking block is distributed on the outer periphery of the front side of the first brake disc. The first connecting disc and the second connecting disc are the same size, so that large impurities from the outside can be blocked from entering between the first brake disc and the second brake disc through the blocking block.

[0009] Preferably, the connecting mechanism includes a fixing ring, which is disposed on the rear side of the second brake disc. A hub mounting plate is fixedly connected to the rear side of the fixing ring. A connecting shaft is inserted into the fixing ring, and a nut is threadedly connected to the front end of the connecting shaft.

[0010] Preferably, the connecting shaft passes through the interior of the first connecting disc and the second connecting disc, and the front side of the fixing ring contacts the rear side of the second brake disc and the second connecting disc, so that the stability between the wheel hub mounting disc and the first brake disc and the second brake disc can be achieved through the connecting shaft.

[0011] Compared with the prior art, this utility model provides a ventilated automotive brake disc, which has the following beneficial effects: This ventilated automotive brake disc, through its ventilation mechanism, creates an efficient ventilation channel between the first and second brake discs during use. Ventilation holes, running through the fixing block and connecting block, provide a smooth path for airflow. Simultaneously, when the first and second brake discs are in use, outside air enters between them via the fixing block for heat dissipation. The arc-shaped first air inlets on both discs actively draw in more cool air, utilizing the airflow during vehicle operation to enhance air circulation efficiency. The circular second air inlets further supplement the airflow, improving heat dissipation in multiple dimensions. This effectively prevents brake performance degradation due to overheating and extends the brake disc's lifespan. A blocking block, fixedly connected to the rear of the first brake disc and distributed around its perimeter, ensures the stability of both brake discs and prevents large impurities from entering between them, guaranteeing structural stability during braking.

[0012] This ventilated automotive brake disc, through a connecting mechanism, has a connecting shaft that passes through the first and second connecting discs, and is then fixed by a nut and a retaining ring, making the entire brake disc firmly connected to the wheel hub mounting plate. This allows it to withstand greater impact and torque during vehicle driving and braking, thus improving driving safety. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] This utility model provides the following technical solution: Example 1:

[0018] Please see Figure 1-6This utility model provides a technical solution: a ventilated automobile brake disc, including a first connecting disc 1, a ventilation mechanism 2 is provided around the first connecting disc 1, and a connecting mechanism 3 is provided behind the ventilation mechanism 2; The ventilation mechanism 2 includes a first brake disc 21, which is fixedly connected to the periphery of the first connecting disc 1. A fixing block 22 is fixedly connected to the rear side of the first brake disc 21. A connecting block 23 is slidably connected inside the fixing block 22. A second brake disc 24 is fixedly connected to the rear side of the connecting block 23. A blocking block 25 is fixedly connected to the front side of the second brake disc 24. A second connecting disc 26 is fixedly connected to the inner side of the second brake disc 24.

[0019] The fixing block 22 and the connecting block 23 are internally connected, and ventilation holes are opened in the fixing block 22 and the connecting block 23 respectively. The two sets of ventilation holes correspond to each other, so that external air can enter between the first brake disc 21 and the second brake disc 24 through the fixing block 22 and the connecting block 23.

[0020] The first brake disc 21 and the second brake disc 24 are respectively provided with first air inlets, and both sets of first air inlets are arc-shaped. The two sets of first air inlets are respectively connected to the interior of the fixing block 22 and the connecting block 23, so as to facilitate the entry of outside air through the first air inlets.

[0021] The first brake disc 21 and the second brake disc 24 are respectively provided with second air inlets, and both sets of second air inlets are circular, which facilitates further improvement of the cooling effect of the first brake disc 21 and the second brake disc 24 through the second air inlets.

[0022] The front side of the blocking block 25 is fixedly connected to the rear side of the first brake disc 21, and the blocking block 25 is distributed on the outer periphery of the front side of the first brake disc 21. The first connecting disc 1 and the second connecting disc 26 are the same size, so that the blocking block 25 can block large impurities from the outside from entering between the first brake disc 21 and the second brake disc 24.

[0023] Example 2: Please refer to Figure 1-6 Furthermore, based on Embodiment 1, the connecting mechanism 3 further includes a fixing ring 31, which is disposed on the rear side of the second brake disc 24. A hub mounting plate 32 is fixedly connected to the rear side of the fixing ring 31. A connecting shaft 33 is inserted into the fixing ring 31, and a nut 34 is threadedly connected to the outer periphery of the front end of the connecting shaft 33.

[0024] The connecting shaft 33 passes through the interior of the first connecting disc 1 and the second connecting disc 26. The front side of the fixing ring 31 contacts the rear side of the second brake disc 24 and the second connecting disc 26, so that the stability between the wheel hub mounting disc 32 and the first brake disc 21 and the second brake disc 24 can be achieved through the connecting shaft 33.

[0025] In actual operation, when this device is in use, the cooperation between the first brake disc 21 and the second brake disc 24 forms an efficient ventilation channel. The ventilation holes that are provided through the fixed block 22 and the connecting block 23 provide a smooth path for air circulation. At the same time, when the first brake disc 21 and the second brake disc 24 are in use, the outside air will enter between them through the guide of the fixed block 22 to dissipate heat. Meanwhile, the arc-shaped first air inlets on the first brake disc 21 and the second brake disc 24 can actively introduce more cold air by utilizing the airflow when the car is running, thereby enhancing the air circulation efficiency. The circular second air inlets further supplement the air intake, improving the heat dissipation effect in multiple dimensions, effectively avoiding the decrease in braking performance caused by overheating of the brake disc, and extending the service life of the brake disc. The blocking block 25 is fixedly connected to the rear side of the first brake disc 21 and the front side of the second brake disc 24, and is distributed on the periphery to ensure the stability of the two brake discs. At the same time, it can prevent large impurities from entering between the first brake disc 21 and the second brake disc 24, thus ensuring the structural stability during braking. The front side of the retaining ring 31 contacts the rear side of the second brake disc 24 and the second connecting disc 26. The connecting shaft 33 is inserted into the inside of the retaining ring 31 and passes through the inside of the second connecting disc 26 and the first connecting disc 1. Then, the nut 34 is threaded to the outer periphery of the front end of the connecting shaft 33. This ensures the stability between the first brake disc 21, the second brake disc 24, the retaining ring 31, and the wheel hub mounting disc 32, making the entire brake disc firmly connected to the wheel hub mounting disc 32. During vehicle driving and braking, it can withstand greater impact force and torque, improving driving safety. After the connection is completed, the brake disc can be installed.
