Abstract
Description
Technical Field
[0001] This utility model relates to a brake pad, specifically a brake pad with a high coefficient of friction, and belongs to the field of brake pad technology. Background Technology
[0002] Brake pads, also known as brake discs, are a key component of a vehicle's braking system. Primarily installed within the brake caliper, they generate braking force through friction with the brake disc, slowing the vehicle down or bringing it to a stop. They are made from various materials; early models used asbestos, but these were phased out due to health hazards. Today, common materials include metal, ceramic, and low-metal types. Semi-metallic brake pads offer good heat dissipation and low cost, making them suitable for ordinary passenger cars; ceramic brake pads are quiet and wear-resistant, ideal for vehicles prioritizing comfort; and low-metal brake pads strike a balance between performance and environmental friendliness. The working condition of the brake pads directly affects driving safety. They must be replaced promptly when worn to their limit, exhibiting abnormal noises, or showing reduced braking force. Avoiding frequent hard braking during daily driving can extend their lifespan.
[0003] During prolonged operation, brake pads generate significant heat through continuous friction, leading to increased friction interface temperature and subsequent material thermal degradation. This reduces the coefficient of friction, impacting braking and transmission performance. Simultaneously, friction produces substantial dust, which, if not promptly removed, accumulates on the friction surface, forming an adhesion layer that hinders direct contact and further weakens friction. The combined effects of increased temperature and dust accumulation often result in decreased frictional performance, sluggish response, and in severe cases, even failure, affecting equipment operational stability and safety. Therefore, this paper proposes a brake pad with a high coefficient of friction. Utility Model Content
[0004] This invention proposes a brake pad with a high coefficient of friction, which can actively dissipate heat and expel dust, thereby improving the friction performance of the brake pad layer.
[0005] This utility model is achieved through the following technical solution: a brake pad with a high coefficient of friction, including a mounting component, wherein the mounting component includes a metal back plate as a structural frame, which provides rigid support through a high-strength metal, such as aluminum alloy or cast iron. A first fixing ear is provided on the top of the metal back plate, and second fixing ears are provided on the left and right sides of the metal back plate. The first fixing ear and the second fixing ear are used to fix the metal back plate in place.
[0006] It also includes a friction component, which is mounted on the mounting component. The friction component includes a brake pad layer and a heat dissipation groove, which is formed on the brake pad layer. The brake pad layer is in direct contact with the brake disc and is made of a mixture of ceramic particles, metal fibers and resin. It is the core component that generates braking force. The heat dissipation groove increases the air contact area and accelerates heat dissipation.
[0007] A base layer is provided on the brake pad layer, and an adhesive layer is provided on the base layer. The adhesive layer is provided on the metal backing plate and is located between the metal backing plate and the base layer. High-temperature resistant epoxy resin adhesive is used to ensure a reliable connection between the metal backing plate and the base layer. The base layer serves as a supporting substrate for the brake pad layer and also has buffering and heat insulation functions.
[0008] It also includes a heat dissipation and dust removal component, which is disposed on the brake pad layer. The heat dissipation and dust removal component includes heat dissipation holes and a cavity. The heat dissipation holes are opened on the brake pad layer, and the cavity is opened inside the brake pad layer. The heat dissipation holes and the cavity are connected.
[0009] The heat dissipation and dust removal component also includes a miniature air pump, on which a positioning plate is fixed, and a positioning hole is provided.
[0010] The miniature air pump is connected to the cavity, and the output end of the miniature air pump is connected to a flexible tube. A connector is threaded onto the flexible tube, and the connector is fixed to the brake pad layer and connected to the cavity. When activated, it can create a negative pressure inside, forcing air to flow into the cavity from the heat dissipation hole and then out through the flexible tube.
[0011] This invention provides a brake pad with a high coefficient of friction, which has the following beneficial effects:
[0012] The high-friction brake pads can create negative pressure inside by activating a micro air pump, forcing air to flow into the cavity through the heat dissipation holes and then out through the hose. This air dissipates the heat generated by the friction between the brake pads and the brake lining layer, and also removes the dust generated by the friction between the brake pads and the brake lining layer, effectively reducing the risk of a large amount of dust adhering to the brake pads. This invention can actively dissipate heat and remove dust, thereby improving the friction performance of the brake pads. Attached Figure Description

The brake pad layer 201 is in direct contact with the brake disc and is made of ceramic particles, metal fibers and resin mixed and pressed. It is the core component that generates braking force. The heat dissipation groove 204 increases the air contact area and accelerates heat dissipation.

[0025] Please refer to this carefully. Figure 3 and Figure 4The adhesive layer 202 is located between the metal backing plate 101 and the base layer 203. It is made of high-temperature resistant epoxy resin to ensure a reliable connection between the metal backing plate 101 and the base layer 203. The base layer 203 serves as the supporting base for the brake pad layer 201 and also has the functions of buffering and heat insulation.
[0026] Please refer to this carefully. Figure 3 and Figure 4 It also includes a heat dissipation and dust removal component 3, which is disposed on the brake pad layer 201.

[0027] Please refer to this carefully. Figure 3 and Figure 4 The heat dissipation and dust removal component 3 also includes a miniature air pump 303, on which a positioning plate 304 is fixed, and a positioning hole 305 is provided.
[0028] Please refer to this carefully. Figure 3 and Figure 4 The miniature air pump 303 is connected to the cavity 302. The output end of the miniature air pump 303 is connected to a hose 306.

[0029] Working principle: The device can be installed through the first fixing ear 102 and the second fixing ear 103. When braking, the brake pad layer 201 and the brake disc will come into contact and generate friction. The friction will generate heat, causing the temperature of the brake pad layer 201 to rise.

[0030] The micro air pump 303 is activated, which creates a negative pressure inside the pump, forcing air to flow from the heat dissipation hole 301 into the cavity 302 and then out through the hose 306. This air dissipates the heat generated by the friction between the brake lining layer 201 and the brake pads, and also removes the dust generated by the friction between the brake lining layer 201 and the brake pads. This effectively reduces the risk of a large amount of dust adhering to the brake lining layer 201. This invention can perform active heat dissipation and remove dust, thereby improving the friction performance of the brake lining layer 201.
