Problems solved by technology
While active shock absorbers can provide ride and handling improvements, they are much more expensive than traditional passive shock absorbers due to the high cost of the electromagnetic materials used in the electromagnetic actuators
Electromagnetic shock absorbers are also expensive as they often require the shock absorber to be redesigned to accommodate the space required for the permanent magnets and multiple coils of the electromagnetic actuator

The present invention provides a damper system for a vehicle comprising an outer tube, a piston rod and a piston assembly mounted to the piston rod and dividing the outer tube into a first working chamber and second studio. A valve assembly mounted to the piston assembly controls fluid flow between the first working chamber and the second working chamber. A magnetic rotor is secured to the outer tube and extends annularly around the outer tube. A stator assembly is coupled to the piston rod by a spherical bearing assembly. The stator assembly includes a plurality of coils that, when energized, apply an active damping force to the piston rod. The coil may also generate electricity through axial movement of the piston rod relative to the outer tube. One or more slip bearings are disposed radially in a slip fit between the coils and the magnetic rotor to stabilize the stator assembly.
Description
technical field [0001] The present disclosure relates to automotive shock absorbers / dampers. More specifically, the present disclosure relates to active shock absorbers / dampers that use electromagnetic actuators to provide different magnitudes based on frequency and input speed to the shock absorber / damper damping. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Shock absorbers are often used in conjunction with automotive suspension systems or other suspension systems to absorb unwanted vibrations that occur during movement of the suspension system. To absorb these unwanted vibrations, automotive shock absorbers are typically connected between the vehicle's sprung mass (body) and the unsprung mass (suspension / drivetrain). [0004] A typical passive shock absorber provides the same amount of damping force regardless of the input freque...
