Technical Field

[0002] The automotive brake pump is a core component of a vehicle's hydraulic braking system. Its core function is to convert the mechanical force applied by the driver to the brake pedal into hydraulic energy, which is then transmitted to the wheel brakes (such as brake calipers or wheel cylinders) via brake fluid, thereby achieving vehicle deceleration or parking. As the "heart" of the braking system, the automotive brake pump ensures vehicle safety through precise hydraulic control. Its design integrates materials science (such as gradient porous structures and ceramic coatings), fluid mechanics, and intelligent control technology, making it a key supporting component for modern automotive safety performance. Existing automotive brake pumps, in order to ensure high-strength operation, often use materials that result in excessive pump weight. Lightweight, high-strength brake pumps are an inevitable choice for the automotive industry to address the energy crisis, safety upgrades, and environmental regulations.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-4As shown, this utility model is a lightweight, high-strength automotive brake pump, including a pump body 1. The outermost side of the pump body 1 is provided with a wear-resistant layer 111, the inner side of the wear-resistant layer 111 is provided with a protective layer 112, and the inner side of the protective layer 112 is provided with a support layer 113. The wear-resistant layer 111 is a nano-ceramic coated aluminum alloy layer, with nano-AlO3-SiC composite ceramic coated on the outside. Compared with traditional cast iron coatings, this increases the wear resistance of the pump body 1. Through the synergistic design of the nano-ceramic coating and the aluminum alloy substrate, while ensuring lightweight design, the wear life of the brake pump reaches 2.5 times that of traditional materials, meeting the high-frequency requirements of automotive braking systems. To meet the demands of high-efficiency and high-load applications, the protective layer 112 comprises a carbon fiber reinforced polymer layer 1121 and a polyimide honeycomb core layer 1122. Through the high strength of the carbon fiber reinforced polymer layer and the structural optimization of the honeycomb core layer, the protective layer 112 achieves a 40% weight reduction while ensuring the brake pump's impact resistance meets standards, satisfying the stringent safety and lightweight requirements of new energy vehicle braking systems. The support layer 113 is a gradient porous aluminum alloy layer. Through gradient porosity design, the support layer 113 achieves a 30% weight reduction while keeping brake fluid temperature fluctuations within ±15℃, meeting the high reliability and thermal management requirements of automotive braking systems.

[0020] The pump body 1 is provided with a piston push rod 2 on its side. The piston push rod 2 is provided with a lubrication layer 211 on its surface and a support layer 113 on its inner side. The lubrication layer 211 is a biomimetic ceramic coating. Ceramic materials themselves have good chemical stability. The biomimetic ceramic coating can remain stable in chemical media such as brake fluid and is not prone to chemical reactions. This ensures the sealing performance and working stability of the piston rod 2, reduces friction, and improves wear resistance and corrosion resistance. It can effectively improve the performance, reliability and service life of the piston push rod 2.

[0021] The pump body 1 is connected to the oil tank 3 at its upper end. The outer surface of the oil tank 3 is provided with an outer layer 311, the inner side of the outer layer 311 is provided with an intermediate layer 312, and the inner side of the intermediate layer 312 is provided with an inner layer 313. The outer layer 311 is composed of TiO nanoparticles and a fluorosilane layer. TiO has excellent chemical stability and can resist the corrosion of brake fluid, water, and acidic substances. The high specific surface area of ​​the nanoparticles can form a dense protective barrier, preventing corrosive media from penetrating into the substrate of the oil tank 3. The fluorosilane is bonded to the surface of the oil tank through chemical bonds, forming a low surface energy hydrophobic film. This membrane can isolate polar molecules such as water molecules in the brake fluid from contact with the metal substrate, inhibiting the occurrence of electrochemical corrosion reactions. It not only meets the stringent requirements for brake fluid storage, but also improves the reliability and durability of the fuel tank 3. The intermediate layer 312 is a gradient porous aluminum alloy layer. Through precise control of porosity, the gradient porous aluminum alloy intermediate layer 312 achieves synergistic optimization of multiple properties such as lightweight, high strength, impact resistance and corrosion resistance of the fuel tank 3. The inner layer 313 is a ceramic composite layer. As the core inner layer of the brake pump fuel tank 3, the ceramic composite layer is usually composed of high temperature resistant ceramics such as Al2O3 and SiC. Its chemical inertness can resist corrosive components such as ethylene glycol and borate esters in the brake fluid, achieving high reliability of brake fluid storage.

[0022] Working principle:

[0023] This lightweight, high-strength automotive brake pump, in its specific operation, achieves a wear life 2.5 times that of traditional materials through the synergistic design of a nano-ceramic coating and an aluminum alloy substrate, ensuring lightweight while extending the pump's wear resistance to 2.5 times that of traditional materials. The high strength of the carbon fiber-reinforced polymer layer and the structural optimization of the honeycomb core layer ensure both high strength and lightweight design of the pump body 1. The biomimetic ceramic coating guarantees the sealing performance and operational stability of the piston rod 2, reducing friction and improving wear and corrosion resistance. The TiO nanoparticles and fluorosilane layer inhibit electrochemical corrosion reactions, meeting the stringent requirements for brake fluid storage and enhancing the reliability and durability of the fuel tank 3. The gradient porous aluminum alloy layer and ceramic composite layer synergistically optimize the fuel tank 3's lightweight, high strength, impact resistance, and corrosion resistance.
