(Summary description)From the day the car was born, the car brake system has played an important role. After more than a hundred years of development, the automobile brake system itself has also undergone tremendous changes.

Mr. Stephane Rolland, Chairman and CEO of Brembo China, said in an interview with Gasgoo recently: “The cars are now faster than a decade ago, and the rich configuration content also makes the whole car heavier. On the one hand, the tires provide better traction, and on the other hand, the brakes must keep up with this trend and improve the overall performance of the vehicle. Compared with the past, the brakes now provide better braking performance and longer service life. , And it is not easy to decay or reach the state of air resistance. NVH (noise vibration and roughness) is another important improvement. Because customers require higher than in the past, the current brake is significantly better than the past in terms of NVH suppression. In addition, due to elimination In addition to harmful substances in brake pads (such as asbestos and copper), current brakes are more environmentally friendly than in the past."

With the transformation of the automotive industry, the evolution of automotive braking systems is still accelerating. Nowadays, there are two major trends in the automotive industry that cannot be ignored: one is the continuous development of new energy vehicles; the other is that ADAS advanced driver assistance systems and autonomous driving have become investment hotspots, and related technologies have gradually become the focus of the industry. Although under these two major trends, the demand for automotive braking systems remains unabated, it is undeniable that automotive braking systems must be "changed" to be able to cope with the challenges brought about by the new trends.

Mr. Stephane Rolland said: "We expect that many changes will occur in the braking system, which are closely related to the promotion of electric vehicles, the development of ADAS (advanced driver assistance systems), and stricter environmental requirements."

Several characteristics of new energy vehicle brake system

When new energy vehicles come, the braking system faces new challenges. Mr. Stephane Rolland pointed out that in the face of the requirements of vehicle electrification, brakes must be lighter than today, they need better corrosion resistance, need to achieve braking "0" drag, and need to be integrated with regenerative braking, and Further reduce dust and particulate matter emissions.

For new energy vehicles, light weight is conducive to increasing the cruising range, not only that, light weight can also achieve the effects of improving handling and comfort. It is understood that Brembo develops and provides brake calipers, brake discs and brake pads for different types of vehicles such as motorcycles, passenger cars and commercial vehicles, and is also a leader in the field of lightweight brake components.

For example, at the Frankfurt International Motor Show in September last year, Brembo introduced a new brake pad with a composite back plate. This cutting-edge design result has passed rigorous bench tests and road tests, and its durability and The braking performance is effectively guaranteed. The new brake pads have reduced weight by more than 60%. At the same time, it completely eliminates corrosion in the caliper body and reduces thermal conductivity, thereby ensuring the highest safety during parking and emergency braking under all road conditions.

"Our main focus is on aluminum passenger car brake calipers, and we have developed a variety of concepts of lightweight brake discs, such as joint cast brake discs. Carbon ceramic fiber brake discs have been produced for nearly 15 years, and we are still Continue to develop other interesting solutions for lightweight brake discs. In addition to the above, we are also committed to developing brake pads with composite back plates. In addition, for new energy vehicles, braking energy recovery and Reuse helps the vehicle decelerate, so the mass of brake discs and brake calipers can be further reduced. In this case, the size of brake discs, brake calipers and brake pads may be greatly reduced." Mr. Stephane Rolland added.
