[0022] 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.
[0023] like Figures 1 to 4 As shown, this utility model provides a motor vehicle brake disc, including a brake disc 1. A mounting base 2 is fixedly connected to the top of the brake disc 1. Several bolts 6 are installed on the inner surface of the mounting base 2. A brake disc 2 3 is fixedly connected to the mounting base 2 by several bolts 6. Several heat dissipation strips 7 are fixedly connected to the corresponding ends of the brake disc 1 and the brake disc 2 3.
[0024] Specifically, the outer surfaces of brake disc 1 and brake disc 2 are specially treated, and both brake disc 1 and brake disc 2 are made of aluminum alloy. With the good thermal conductivity of aluminum alloy and the wear-resistant properties of the special treatment layer, the overall weight of the brake disc is reduced, and the wear resistance and service life of the brake disc are improved.
[0025] like Figures 1 to 4 As shown, the top of the mounting base 2 is provided with a positioning hole 8 and several mounting holes 5. With the precise positioning of the positioning hole 8 and the convenient installation of the bolts 6 by the mounting holes 5, the installation of the brake disc is more convenient and accurate, improving installation efficiency and compatibility.
[0026] Furthermore, several grooves 9 are provided on one side of both brake disc 1 and brake disc 3, which are opposite each other. The grooves 9 are all arc-shaped. Under the guiding effect of the grooves 9, debris and other impurities generated during braking can be discharged, reducing the impact of impurities on the friction surface of the brake disc and ensuring braking performance.
[0027] like Figures 1 to 4 As shown, both brake disc 1 and brake disc 3 have several through holes 10 at one end. The holes 10 promote air circulation, which further enhances the heat dissipation performance of the brake disc, reduces the temperature of the brake disc, and also reduces the weight of brake disc 1 and brake disc 3.
[0028] It is worth noting that several heat dissipation strips 7 are arranged in a ring array, and several heat dissipation strips 7 are all arc-shaped, which can dissipate heat from the brake disc more evenly, and have a better effect on air disturbance when the brake disc rotates, thus improving heat dissipation efficiency.
[0029] like Figures 1 to 4As shown, both brake disc 1 and brake disc 2 are fixedly fitted with buffer rings 4. The buffer rings 4 are made of nitrile rubber. Under the elastic buffering effect of the buffer rings 4, they can effectively absorb the vibration and noise generated during braking and improve the comfort of driving.
[0030] Working principle and process: When a vehicle brakes, the brake caliper applies pressure to brake disc 1 and brake disc 3, and the friction between the two and the brake pads generates braking force to decelerate the vehicle. During this process, a large amount of heat generated by braking is conducted through the aluminum alloy brake disc 1 and brake disc 3 to the heat dissipation strip 7. The heat dissipation strip 7 is arranged in a ring array and has an arc shape, which can effectively exchange heat with the air and dissipate the heat. The through-hole 10 and the arc-shaped groove 9 also help to promote airflow and enhance heat dissipation. At the same time, the buffer ring 4 can absorb the vibration and noise generated during braking, and the positioning hole 8 and mounting hole 5 on the mounting base 2 ensure the accuracy and stability of the brake disc installation.
[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
