After redesigning the blueprint for a traditional axle, American Axle and Manufacturing (AAM), a large automotive supplier in Detroit, developed what it calls Quantum driveline technology to reduce mass and increase power density, minimize noise vibration and harshness, as well as offer efficiency gains in a more compact system package.
“Quite simply, AAM’s Quantum is a game changer,” says David C. Dauch, chairman and CEO of AAM. “What started as a spark of an idea with our engineers has progressed to a proven technology that will increase vehicle efficiency, improve fuel economy, and increase power density. Our customers will see a difference in axle packaging, and drivers will see a difference at the gas pump.”
After several years of benchmarking non-automotive products, running tests, and securing more than 12 patents, AAM’s engineers redesigned virtually every aspect of the axle, and the resulting Quantum family of axles yields gains in efficiency, performance, and packaging, while reducing system weight.
The new design arranges bearings more efficiently and sets gears in optimal positions, while also combining functions of many components and developing new lubricants to increase system efficiency and durability.
Quantum beam axles are scalable and can be adapted for use on any size truck or passenger vehicle, including all rear-wheel-drive and all-wheel-drive passenger vehicles, crossovers, and SUVs.
