Abstract: A damper system for a vehicle is provided that includes a pressurized gas damper, electromagnetic actuator, and pressurized gas spring. The pressurized gas damper includes first and second working chambers that are fluidly connected by a flow control orifice. The electromagnetic actuator includes a stator assembly with a stator cavity and a magnetic rotor that is slidingly received in the stator cavity. The magnetic rotor is fixed to a damper tube that houses the second working chamber. The stator cavity and an end of the damper tube cooperate to define the first working chamber. The pressurized gas spring includes a bellows chamber that extends annularly about the damper tube. The damper tube includes an opening between the second working chamber and the bellows chamber.

Abstract: A damper system for a vehicle is provided that includes an outer tube, a piston rod, and a piston assembly that is mounted to the piston rod and separates the outer tube into first and second working chambers. A valve assembly, mounted to the piston assembly, controls fluid flow between the first and second working chambers. A magnetic rotor is fixed to and extends annularly about 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 apply an active damping force to the piston rod when energized. The coils can also generate electricity from axial movements of the piston rod relative to the outer tube. One or more glide bearings are disposed radially between the coils and the magnetic rotor in a sliding fit to stabilize the stator assembly.

Abstract: A damper system for a vehicle is provided that includes a damper and actuator. The damper extends longitudinally along a damper axis between first and second damper ends. The actuator is separate and spaced apart from the damper. The actuator extends longitudinally along an actuator axis between first and second actuator ends. The damper and the actuator are arranged next to one another where the actuator axis is spaced from and substantially parallel to the damper axis. The damper and the actuator are positioned within a cylindrical packaging envelope that has a diameter of 300 millimeters or less. The cylindrical packaging envelope is an imaginary cylinder, which may be defined by one or more components of a vehicle's suspension system such as a coil spring or an upper suspension arm. The damper and the actuator are completely contained within the cylindrical packaging envelope.
