Description

Technical Field

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

[0002] Automotive brakes are the braking devices used in automobiles. Almost all automotive brakes are friction-type, and can be broadly classified into drum brakes and disc brakes. In a drum brake, the rotating element in the friction pair is the brake drum, whose working surface is a cylinder. In a disc brake, the rotating element is the rotating brake disc, with its end face as the working surface. Automotive brakes are components that generate forces that impede the movement or tendency of a vehicle to move, including devices in auxiliary braking systems.

[0003] Existing automotive brakes rely on friction between brake pads and brake discs during braking. However, brake pads generate heat and can even overheat after this friction, which can negatively impact braking performance. Current brake pad cooling systems rely on airflow generated during driving, but lack proper airflow guidance, resulting in poor heat dissipation. Therefore, a brake roller assembly that can effectively concentrate and guide airflow to enhance brake pad cooling is needed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a brake roller assembly to solve the problems mentioned in the background section.

[0005] This utility model discloses a brake roller assembly, including a brake disc and a brake caliper. The center of one side of the brake disc is connected to the axle. The bottom end of one side of the brake caliper is fixedly installed on the top of the axle and mounted on the outside of the brake disc. The brake caliper has an n-shaped structure and an air guide assembly is installed on its inner side. The air guide assembly includes two sets of air guide tubes and an air guide cover. A brake pad controlled by a piston is installed on the inner side of the brake caliper near the lower part of the air guide tubes. Air outlets are evenly opened on the bottom end face of the air guide tubes, and the air outlets face the upper surface of the brake pads.

[0006] As a further improvement of this utility model, a mounting groove is provided in the center of the brake disc, and a first heat dissipation hole is provided at equal intervals around the outer side of the brake disc in a ring.

[0007] As a further improvement of this utility model, a second heat dissipation hole is provided on both sides of the outer side of the brake disc near the first heat dissipation hole, and the second heat dissipation hole is connected to the mounting groove. A third heat dissipation hole is uniformly provided through the front of the brake disc.

[0008] As a further improvement of this utility model, the inner cavity of the brake caliper is filled with hydraulic oil, and an oil inlet pipe is fixedly connected to one side of the brake caliper, with the inner cavity of the oil inlet pipe communicating with the hydraulic oil inside the brake caliper.

[0009] As a further improvement of this utility model, two connecting columns are fixedly connected to one side of the air guide tube, and the air guide tube is connected and fixed to the inside of the brake caliper through the connecting columns.

Detailed Implementation

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0025] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] Please see Figure 1-6This utility model includes a brake disc 01 and a brake caliper 02. The center of one side of the brake disc 01 is connected to the axle 014. The bottom of one side of the brake caliper 02 is fixedly installed on the top of the axle 014 and mounted on the outside of the brake disc 01. The brake caliper 02 has an n-shaped structure and an air guide assembly is installed on the inside. The air guide assembly includes two sets of air guide tubes 03 and an air guide cover 032. A brake pad 021 controlled by a piston 022 is installed on the inside of the brake caliper 02 near the bottom of the air guide tubes 03. Air outlets 033 are evenly opened on the bottom surface of the air guide tubes 03 and face the upper surface of the brake pad 021.

[0027] Please see Figure 1 and Figure 2 In this embodiment, in order to better dissipate heat from the brake disc 01, a mounting groove 013 is provided in the center of the brake disc 01, and first heat dissipation holes 011 are provided at equal intervals around the outer side of the brake disc 01.

[0028] The brake disc 01 has a second heat dissipation hole 012 on both sides of the outer side near the first heat dissipation hole 011. The second heat dissipation hole 012 is connected to the mounting groove 013. The brake disc 01 has a third heat dissipation hole 015 evenly distributed through the front.

[0029] When the car is in motion, airflow enters the first heat dissipation hole 011 and carries away heat, and passes through the second heat dissipation hole 012 and the third heat dissipation hole 015, thereby further dissipating heat from the brake disc 01.

[0030] Please see Figure 1 and Figure 6 It should be noted that, in order to better control the brake pads 021 for braking, the inner cavity of the brake caliper 02 is filled with hydraulic oil 023, and an oil inlet pipe 024 is fixedly connected to one side of the brake caliper 02. The inner cavity of the oil inlet pipe 024 is connected to the hydraulic oil 023 inside the brake caliper 02.

[0031] When it is necessary to brake the brake disc 01 through the brake pads 021, the brake pedal is pressed inside the car, causing hydraulic oil 023 to be injected into the brake caliper 02 through the oil inlet pipe 024. The pressure of the hydraulic oil 023 pushes the piston 022 and the brake pads 021 to clamp on both sides of the brake disc 01 for braking.

[0032] Please see Figure 3 and Figure 4 Specifically, in order to better dissipate heat from the brake pads 021, two connecting posts 031 are fixedly connected to one side of the air duct 03. The air duct 03 is connected and fixed to the inside of the brake caliper 02 through the connecting posts 031. The air duct cover 032 has a horn-shaped structure and faces the front of the vehicle.

[0033] An exhaust port 035 is provided at the end of the air duct 03 away from the air guide cover 032. The exhaust port 035 is rectangular and a guide vane 034 is fixedly connected to the exhaust port 035. The guide vane 034 is used to guide the airflow at the exhaust port 035.

[0034] When the car is in motion, airflow enters the air duct 03 from the air guide 032. Some airflow blows onto the upper surface of the brake pad 021 from multiple air outlets 033, and some airflow is discharged from the exhaust port 035. Together with the air guide plate 034, the airflow is blown to one side of the brake pad 021, thereby better dissipating heat from the brake pad 021.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
