FYI: General Motors is exploring innovative suspension system technology with patent applications for adaptive springs.
GM’s Next Step in Suspension Innovation
General Motors (GM) is delving into the future of vehicle suspension systems by considering adaptive spring technology, building upon their prior breakthrough with magnetorheological dampers. This insight comes to light from a recent patent application published by the United States Patent and Trademark Office (USPTO) on November 7, 2024. Filed initially on May 5, 2023, the document highlights GM’s continued dedication to vehicle performance enhancements.
Pioneering Magnetorheological Technology
GM has been at the forefront of magnetorheological damper technology, which employs magnetic fluid to swiftly adjust damper stiffness. This technology already allows for dynamic switching between firmness and softness, offering improved ride comfort and performance. Their latest patent application proposes extending this innovative approach to vehicle springs.
Understanding the Adaptive Spring Design
The detailed patent outlines a system involving double springs with a central seat featuring an outer sleeve filled with magnetorheological fluid and an integrated electromagnet. When the electromagnet is activated, the fluid’s viscosity increases, restricting spring movement, thus stiffening the suspension. Conversely, deactivating the magnet lowers fluid viscosity, permitting more movement and enhancing ride comfort.
Potential Integration with MagneRide
The possible evolution of GM’s MagneRide system could include these adaptive springs, enhancing the system’s ability to deliver a tailored driving experience across various conditions. Although patent filings do not always become commercial products, the integration of such technology seems plausible, given GM’s commitment to innovative vehicle solutions.
Competition and Industry Movements
While GM leads this domain, other manufacturers are also pushing boundaries. For instance, Ford is focusing on their Multimatic DSSV (Dynamic Suspension Spool Valve) dampers, as seen in the Chevrolet Colorado ZR2. This suggests a bustling landscape of advancements in suspension technology.
