Description

Technical Field

[0001] This application belongs to the technical field of automotive brakes, and particularly relates to an automotive brake. Background Art

[0002] An automotive brake is a braking device for an automobile. Almost all brakes used in automobiles are friction brakes, which can be divided into two major categories: drum brakes and disc brakes. The rotating element in the friction pair of a drum brake is a brake drum, and its working surface is a cylindrical surface. The rotating element of a disc brake is a rotating brake disc, with its end face as the working surface. There is a hydraulic type of disc brake, which is hydraulically controlled. Its main components include a brake disc, a wheel cylinder, a brake caliper, and oil pipes. Disc brakes have the advantages of fast heat dissipation, light weight, simple structure, convenient adjustment, especially good high-temperature resistance performance under high loads, stable braking effect, and are not afraid of mud and water invasion. Many sedans use disc brakes when driving in winter and under harsh road conditions.

[0003] The patent with the publication number CN221299894U discloses a new type of disc brake, which relates to the technical field of braking equipment. The utility model includes a brake disc, a caliper housing, and a conveying sleeve. A through hole is formed in the center of the front end face of the brake disc, and heat dissipation fins are fixedly arranged in an annular array outside the through hole on the front end face of the brake disc. A caliper housing is arranged on the upper part outside the brake disc, and a conveying sleeve is arranged above the caliper housing. Both ends of the conveying sleeve are fixedly connected and communicated with a rotary joint pipe.

[0004] The above patent reduces heat through the cooperation of heat dissipation fins and heat dissipation holes. Although it can achieve a certain heat dissipation effect, the heat dissipation effect is poor and the efficiency is low, and it still needs to be enhanced. Utility Model Content

[0005] The purpose of this application is to provide an automotive brake that can solve the above problems.

[0006] The purpose of this application is to provide an automotive brake, including:

[0007] A brake disc, which is arranged on and connected to the axle and rotates with the axle. The brake disc includes two spaced-apart disc bodies:

[0008] A brake caliper, which is arranged on the brake disc;

[0009] Brake pads, which are arranged on the brake caliper and include a first brake pad and a second brake pad. The two brake pads are respectively on both sides of the brake disc, and brake linings are arranged on each brake pad and are in contact with the brake disc;

[0010] A heat dissipation structure, which is arranged on the brake disc for heat dissipation;

[0011] Among them, it further includes a hydraulic cylinder, including a cylinder and a piston, for controlling the tightening and loosening of the brake pads.

[0012] Using the above-mentioned automotive brake design, by designing two spaced-apart discs, the contact area with the brake pads is increased, so that the braking force can be more evenly distributed during braking, thereby improving the braking efficiency. By setting up a heat dissipation structure, during the braking process, a large amount of heat will be generated by the friction between the brake pads and the brake disc. If not dissipated in time, it may lead to a decline in braking performance or even failure. The setting of the heat dissipation structure can effectively accelerate the conduction and dissipation of heat, maintain the appropriate working temperature of the brake disc and the brake pads, thereby extending the service life and enhancing the braking performance. Using a hydraulic cylinder (including a cylinder and a piston) to control the tightening and loosening of the brake block, this design realizes the precise adjustment of the braking force, and has the advantages of fast response speed, high control precision, and labor-saving operation. At the same time, through the improvement of braking efficiency and the optimization of heat dissipation performance, more stable braking performance can be maintained during emergency braking or long-term braking, reducing the braking distance and improving driving safety.

[0013] Furthermore, the brake caliper includes a bracket and a caliper body. The caliper body can slide on the bracket, and there is only one piston and it is located on one side of the caliper body.

[0014] By using only one piston to control the movement of the caliper body, compared with the traditional double-piston or multi-piston design, this structure is more compact and has a lower cost, with fewer failure points and lower maintenance costs. When the pressure in the cylinder pushes the piston, the brake pads on one side of the piston cylinder will first contact the brake disc. Since the caliper body can slide on the bracket, this contact on one side will immediately generate a reaction force, pushing the entire caliper body to move to the other side, so that the brake pads on the other side also quickly contact the brake disc, shortening the time required for the brake pads on both sides to contact the brake disc simultaneously and improving the braking response speed. And although only one piston provides the initial driving force, the design of the caliper body ensures that the brake pads on both sides can contact the brake disc almost simultaneously and with similar forces, and the resulting balanced braking force distribution can reduce the uneven wear phenomenon during braking and extend the service life of the brake pads and the brake disc.

[0015] Furthermore: The heat dissipation structure includes:

[0016] Air guiding rib strips, arranged between the two discs, and the air guiding rib strips include;

[0017] The first rib strip, arranged radially along the disc;

[0018] The second rib strip, arranged on both sides of the first rib strip and in an arc shape;

[0019] Wherein, a first air flow channel is formed between the first rib strip and the second rib strip, and a second air flow channel is formed between adjacent second rib strips.

[0020] The air guiding ribs include a first rib and a second rib, which guide the flow of air inside the brake disc. The first rib is arranged radially along the disc body, providing the main flow direction for the air. The second rib is arc-shaped, further refining the air flow path and increasing the contact area and contact time between the air and the disc surface. At the same time, the first air guiding channel formed between the first rib and the second rib, and the second air guiding channel formed between adjacent second ribs together constitute an efficient heat dissipation channel network. These channels can guide the air to form vortices or turbulence inside the brake disc, thereby enhancing the heat convection and heat transfer effects, helping to reduce the performance degradation or component damage caused by local overheating, keeping the brake disc within an appropriate working temperature range, which helps to improve the stability and reliability of the braking system, extend the service life of the brake disc, and ensure the safety performance of the vehicle under extreme conditions.

[0021] Furthermore, the first air guiding channel is arranged radially along the disc body, and there are multiple first air guiding channels, and their inlets are evenly distributed on the outer peripheral surface of the disc body.

[0022] The inlets of multiple first air guiding channels are evenly distributed on the outer peripheral surface of the disc body, ensuring that the air can enter the brake disc evenly, avoiding local overheating problems caused by uneven air flow distribution, and enabling effective heat dissipation on the entire surface of the brake disc. At the same time, the first air guiding channel is arranged radially along the disc body, which means that when the air flows through these channels, it can directly contact the internal structure of the disc body, thereby more effectively transferring heat and improving the heat dissipation efficiency.

[0023] Furthermore, the second air guiding channel is arc-shaped, and its length gradually increases from the first reverse flow channel outward, and its inlets are distributed on the outer peripheral surface of the disc body.

[0024] The arc-shaped design of the second air guiding channel enables the air to flow along a certain curvature direction when flowing through. This guiding effect helps to guide more air into the brake disc. And because the length of the second air guiding channel gradually increases from the first air guiding channel outward, this design enables the air to gradually spread out after entering the brake disc, forming a more uniform air flow distribution and improving the heat dissipation effect of the entire brake disc. The arc-shaped design helps to reduce the resistance of the air during the flow process, enabling the air to pass through the second air guiding channel more smoothly, which can not only improve the heat dissipation efficiency but also reduce the noise and vibration generated due to air flow obstruction.

[0025] Furthermore, there are multiple second air guiding channels, and each second air guiding channel is divided into two groups and symmetrically distributed on both sides of the first air guiding channel.

[0026] By increasing the number of the second air guiding channels and dividing them into two groups symmetrically distributed on both sides of the first air guiding channel, the flow path and contact area of air inside the brake disc can be significantly increased, which helps to more evenly disperse and dissipate the heat generated during braking, further improving the heat dissipation effect. Moreover, the symmetrically distributed second air guiding channels contribute to forming a more balanced air flow distribution. When air enters the inside of the brake disc, it will be evenly guided by the second air guiding channels on both sides, reducing the local overheating phenomenon caused by uneven air flow distribution.

[0027] The beneficial effects of this application are as follows:

[0028] 1. By setting up the heat dissipation structure, the conduction and dissipation of heat can be effectively accelerated, maintaining the appropriate working temperature of the brake disc and brake pads, thereby extending the service life and improving the braking performance;

[0029] 2. By using only one piston to control the movement of the caliper body, compared with the traditional double-piston or multi-piston design, this structure is more compact and has a lower cost, with fewer failure points and lower maintenance costs. It shortens the time required for the brake pads on both sides to contact the brake disc simultaneously, improves the braking response speed, and also ensures that the brake pads on both sides can contact the brake disc almost simultaneously and with similar forces. The resulting balanced braking force distribution can reduce the uneven wear phenomenon during braking and extend the service life of the brake pads and brake disc;

[0030] 3. Through the settings of the first air guiding channel and the second air guiding channel, they jointly constitute an efficient heat dissipation channel network. These channels can guide the air to form vortices or turbulences inside the brake disc, thereby enhancing the heat convection and heat transfer effects, helping to reduce the performance degradation or component damage caused by local overheating, maintaining the brake disc within the appropriate working temperature range, which contributes to improving the stability and reliability of the braking system, extending the service life of the brake disc, and ensuring the safety performance of the vehicle under extreme conditions.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0037] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0038] Next, in conjunction with the accompanying drawings, through specific embodiments and their application scenarios, the... provided by the embodiments of the present application will be described in detail.

[0039] Embodiment 1:

[0040] As Figures 1 to 3 shown, the embodiment of the present application provides an automotive brake, including:

[0041] A brake disc 100, which is arranged on the axle and connected to the axle, rotates together with the axle. The brake disc 100 includes two spaced-apart disc bodies 110:

[0042] A brake caliper 200, which is arranged on the brake disc 100;

[0043] Brake pads, which are arranged on the brake caliper 200, include a first brake pad 300 and a second brake pad 310. The two brake pads are respectively on both sides of the brake disc 100, and a brake lining 320 is arranged on each brake pad. The brake lining 320 contacts the brake disc 100;

[0044] A heat dissipation structure 500, which is arranged on the brake disc 100 for heat dissipation;

[0045] Among them, it also includes a hydraulic cylinder 400, which includes a cylinder and a piston and is used to control the tightening and loosening of the brake pads.

[0046] In some implementation manners of the embodiments of the present application, as Figure 1 shown, by adopting the above-mentioned design of an automotive brake, by designing two spaced-apart discs 110, the contact area with the brake pads 320 is increased, so that the braking force can be more evenly dispersed during braking, thereby improving the braking efficiency. By providing a heat dissipation structure 500, during the braking process, a large amount of heat will be generated by the friction between the brake pads 320 and the brake disc 100. If it is not dissipated in time, it may lead to a decline in braking performance or even failure. The setting of the heat dissipation structure 500 can effectively accelerate the conduction and dissipation of heat, maintain the appropriate working temperature of the brake disc 100 and the brake pads 320, thereby extending the service life and improving the braking performance. The hydraulic cylinder 400 (including a cylinder and a piston) is used to control the tightening and loosening of the brake blocks. This design realizes the precise adjustment of the braking force, and has the advantages of fast response speed, high control accuracy, and labor-saving operation. At the same time, through the improvement of braking efficiency and the optimization of heat dissipation performance, more stable braking performance can be maintained during emergency braking or long-term braking, reducing the braking distance and improving driving safety.

[0047] In addition, the brake caliper 200 includes a bracket 210 and a caliper body 220. The caliper body 220 can slide on the bracket 210, and there is only one piston and it is located on one side of the caliper body 220.

[0048] By using only one piston to control the movement of the caliper body 220, compared with the traditional double-piston or multi-piston design, this structure is more compact and has a lower cost, with fewer failure points and lower maintenance costs. When the pressure in the cylinder pushes the piston, the brake pads 320 on one side of the piston cylinder will first contact the brake disc 100. Since the caliper body 220 can slide on the bracket 210, this contact on this side will immediately generate a reaction force, pushing the entire caliper body 220 to move to the other side, so that the brake pads 320 on the other side also quickly contact the brake disc 100, shortening the time required for the brake pads 320 on both sides to contact the brake disc 100 simultaneously and improving the braking response speed. And although only one piston provides the initial driving force, the design of the caliper body 220 ensures that the brake pads 320 on both sides can contact the brake disc 100 almost simultaneously and with similar forces, and the resulting balanced braking force distribution can reduce the uneven wear phenomenon during braking and extend the service life of the brake pads 320 and the brake disc 100.

[0049] Embodiment 2:

[0050] The embodiments of the present application provide an automotive brake. In addition to including the above technical features, the automotive brake of the embodiments of the present application further includes the following technical features.

[0051] As shown in FIG. 4, the heat dissipation structure 500 includes:

[0052] Air guiding rib strips are arranged between two disk bodies 110. The air guiding rib strips include:

[0053] A first rib strip 520 is arranged along the radial direction of the disk body 110;

[0054] A second rib strip 530 is arranged on both sides of the first rib strip 520 and is arc-shaped;

[0055] Wherein, a first air guiding flow channel 540 is formed between the first rib strip 520 and the second rib strip 530, and a second air guiding flow channel 550 is formed between adjacent second rib strips 530.

[0056] The air guiding rib strips include a first rib strip 520 and a second rib strip 530, which guide the flow of air inside the brake disc 100. The first rib strip 520 is arranged along the radial direction of the disk body 110, providing a main flow direction for the air. The second rib strip 530 is arc-shaped, further refining the air flow path and increasing the contact area and contact time between the air and the surface of the disk body 110. At the same time, the first air guiding flow channel 540 formed between the first rib strip 520 and the second rib strip 530, and the second air guiding flow channel 550 formed between adjacent second rib strips 530 together constitute an efficient heat dissipation channel network. These flow channels can guide the air to form vortices or turbulences inside the brake disc 100, thereby enhancing the heat convection and heat transfer effects, helping to reduce the performance degradation or component damage caused by local overheating, keeping the brake disc 100 within an appropriate working temperature range, which helps to improve the stability and reliability of the braking system, extend the service life of the brake disc 100, and ensure the safety performance of the vehicle under extreme conditions.

[0057] Embodiment 3:

[0058] The embodiment of the present application provides an automotive brake. In addition to including the above technical features, the automotive brake of the embodiment of the present application further includes the following technical features.

[0059] As Figure 4 shown, the first air guiding flow channel 540 is arranged along the radial direction of the disk body 110, and a plurality of first air guiding flow channels 540 are provided, and their inlets are evenly distributed on the outer peripheral surface of the disk body 110.

[0060] In the embodiments of the present application, the inlets of multiple first air guiding channels 540 are evenly distributed on the outer peripheral surface of the disc body 110, ensuring that air can enter the brake disc 100 evenly, avoiding local overheating problems caused by uneven air flow distribution, and enabling effective heat dissipation on the entire surface of the brake disc 100. At the same time, the first air guiding channels 540 are arranged radially along the disc body 110, which means that when air flows through these channels, it can directly contact the internal structure of the disc body 110, thereby transferring heat more effectively and improving the heat dissipation efficiency.

[0061] Embodiment 4:

[0062] The embodiments of the present application provide an automotive brake. In addition to including the above technical features, the automotive brake of the embodiments of the present application further includes the following technical features.

[0063] As Figure 4 shown, the second air guiding channel 550 is arc-shaped, and its length gradually increases from the first reverse flow channel outward, and its inlets are distributed on the outer peripheral surface of the disc body 110.

[0064] In the embodiments of the present application, the arc-shaped design of the second air guiding channel 550 enables air to flow along a certain curvature direction when flowing through it. This guiding effect helps to guide more air into the brake disc 100. And because the length of the second air guiding channel 550 gradually increases from the first air guiding channel 540 outward, this design enables the air to gradually spread after entering the brake disc 100, forming a more uniform air flow distribution and improving the heat dissipation effect of the entire brake disc 100. The arc-shaped design helps to reduce the resistance of air during the flowing process, enabling air to pass through the second air guiding channel 550 more smoothly, which can not only improve the heat dissipation efficiency but also reduce the noise and vibration generated due to air flow obstruction.

[0065] Furthermore, multiple second air guiding channels 550 are provided, and each second air guiding channel 550 is divided into two groups and symmetrically distributed on both sides of the first air guiding channel 540.

[0066] In some embodiments of the present application, by increasing the number of the second air guiding channels 550 and dividing them into two groups and symmetrically distributing them on both sides of the first air guiding channel 540, the flow path and contact area of air inside the brake disc 100 can be significantly increased, which helps to more evenly disperse and dissipate the heat generated during the braking process and further improve the heat dissipation effect. And the symmetrically distributed second air guiding channels 550 help to form a more balanced air flow distribution. When air enters the brake disc 100, it will be evenly guided by the second air guiding channels 550 on both sides, reducing the local overheating phenomenon caused by uneven air flow distribution.

[0067] It should be noted that in this text, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements that are inherent to such process, method, article or device.
