Apple granted patent for a ‘Mass Damper System’ for a vehicle

Apple may have abandoned plans for an Apple Car, but the tech giant is still being granted patents related to vehicle technology. One of the latest is number US 12017498 B2 for a “Mass Damper System.”

About the patent

The patent involves vehicle suspensions systems. Such systems, of course, are used to reduce the transmission of vibrations between two components. In a vehicle, a sprung mass of the vehicle typically includes the body and passenger compartment of the vehicle and the passenger compartment of the vehicle, and an unsprung mass of the vehicle typically includes tires, wheels, and components directly connected to the wheel. 

The vehicle suspension supports the sprung mass with respect to the unsprung mass and reduces transmission of vibrations from the unsprung mass of the vehicle to the sprung mass of the vehicle. Apple’s patent involves suspension systems include a mass damper system to reduce unwanted vibration effects.

Summary of the patent

Here’s Apple’s abstract of the patent: “A mass damper system includes an unsprung mass, a sprung mass, a suspension component that supports the sprung mass with respect to the unsprung mass, and a damper mass that is connected to the unsprung mass. Motion control components are connected to the sprung mass and a fluid-operated system that transfers forces between the motion control components and the damper mass to regulate motion of the damper mass with respect to the unsprung mass.”
