Rapid Development, Braking Benchmark
– – Kingracing Announces Development Achievements for Hongqi E-HS9 Braking Components
In the field of high-end new energy vehicle braking systems, Kingracing consistently uses technology as its spear and efficiency as its shield. With its profound R&D technology and agile project response capabilities, it has become the first manufacturer in the industry to complete the development of dedicated brake pads and brake discs for the Hongqi E-HS9, creating an exclusive safe braking solution for this flagship pure electric SUV.
As a pure electric luxury SUV, the Hongqi E-HS9’s vehicle weight and power output place stringent demands on the heat resistance and stability of the braking system. For the development of the front brake pads, we used a high-performance composite ceramic formula, precisely matching the main braking force requirements of the front wheels. The friction coefficient remains stable in the 0.4-0.45 range, effectively resisting high-temperature heat decay caused by continuous braking, ensuring precise and powerful braking response during high-speed emergency braking and on long downhill sections.
The rear brake pads focus on optimizing both braking smoothness and durability. Environmentally friendly low-metal materials are used, significantly reducing braking noise and dust emissions while ensuring sufficient braking force. It also adapts to the working characteristics of the vehicle’s energy recovery system, achieving a balance between braking performance and energy saving, providing a quieter and more comfortable driving experience for passengers.
Brake Disc
The front brake discs use high-purity alloy cast iron material, combined with an enlarged ventilation and heat dissipation channel design, significantly improving heat dissipation efficiency and avoiding thermal deformation and braking judder caused by prolonged braking; the disc surface is precisely polished and treated with anti-rust treatment, ensuring both wear resistance and corrosion resistance, extending the service life of the components.
The rear brake discs adopt a lightweight design concept, optimizing weight while ensuring structural strength, improving vehicle handling flexibility; at the same time, a grooved ventilation structure is used to quickly dissipate brake dust and heat, further enhancing braking stability and providing comprehensive protection for the Hongqi E-HS9 in all driving scenarios.
From project initiation to actual vehicle testing, Kingracing completed the entire development of the front and rear brake pads and brake discs for the Hongqi E-HS9 at a speed far exceeding industry standards. In the future, we will continue to focus on innovation in braking technology for new energy vehicles, providing higher-quality products and more efficient responses to support the upgrading of the high-end automotive industry.
