This technology is making a surprising comeback to the forefront. The automotive group Stellantis has indeed filed a patent for a new generation of drum brakes. This major innovation is a direct response to the upcoming Euro 7 anti-pollution standards, known to be particularly demanding for traditional braking systems.
A Response to Euro 7 Standards
The main objective of this new patented system is to meet the strict requirements of the upcoming Euro 7 standards. These European regulations, set to come into effect in the coming years, aim to drastically reduce the polluting emissions of all vehicles, not just those from the engine. They also target particles emitted by tire and brake wear.
Capturing Brake Dust
The particularity of this Stellantis patent lies in its ability to capture brake dust. Unlike disc brakes, which release these fine particles directly into the air, the new closed-circuit design of the drums would allow them to contain and collect them effectively. This technological advancement would thus significantly limit the emissions of polluting particles, a major health and environmental issue.
The Revival of an Old Technology
Long neglected in favor of disc brakes, often perceived as more efficient, drum brakes could thus experience a true revival. Their encapsulated architecture proves to be a decisive asset in addressing the challenges of particulate pollution. Stellantis is betting on this reinvented technology to equip its future vehicles, anticipating regulations that will impact the entire automotive industry.
