Publication number: 20240066940Abstract: An air-spring assembly includes a flexible bellows extending from a top end to a bottom end and enclosing an air-spring chamber between the top end and the bottom end, a first panel partially defining the air-spring chamber and movable in response to a pressure of the air-spring chamber, an enclosure partially defining a working chamber fluidly isolated from the air-spring chamber, a second panel partially defining the working chamber and movable relative to the enclosure, and a linkage member fixed relative to the first panel and to the second panel and defining a fixed distance between the first panel and the second panel. The top and bottom ends are fixable to a frame and a wheel of a vehicle, respectively. A volume of the air-spring chamber varies with movement of the bottom end relative to the top end. Movement of the second panel changes a volume of the working chamber.Type: ApplicationFiled: August 30, 2022Publication date: February 29, 2024Applicant: DRiV Automotive Inc.Inventors: Miguel Dhaens, Monzer Al Sakka, Emilie Florence Simone Boulay, Vytautas Bucinskas

Patent number: 11338637Abstract: 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.Type: GrantFiled: January 28, 2019Date of Patent: May 24, 2022Assignee: TENNECO AUTOMOTIVE OPERATING COMPANY INC.Inventors: Miguel Dhaens, Monzer Al Sakka, Christophe Lauwerys

Publication number: 20220144035Abstract: The active suspension system includes right and left dampers, a pump, and a control valve system. Each of the right and left dampers includes a damper housing, a piston rod, and a piston that is mounted on the piston rod. The piston is arranged in sliding engagement inside the damper housing such that the piston divides the damper housing into first and second working chambers. The pump includes a pump intake and a pump outlet. The control valve system is connected in fluid communication with the first and second working chambers of the right damper, the first and second working chambers of the left damper, the pump intake, and the pump outlet. The control valve system has several different arrangements of fluid flow paths that provide different working modes for the active suspension system.Type: ApplicationFiled: April 15, 2020Publication date: May 12, 2022Inventors: Monzer AL SAKKA, Miguel DHAENS

Patent number: 10690215Abstract: 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.Type: GrantFiled: February 23, 2018Date of Patent: June 23, 2020Assignee: Tenneco Automotive Operating Company Inc.Inventors: Monzer Al Sakka, Miguel Dhaens, Christophe Lauwerys, Thibault Le Polain

Patent number: 10589591Abstract: 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.Type: GrantFiled: February 23, 2018Date of Patent: March 17, 2020Assignee: Tenneco Automotive Operating Company Inc.Inventors: Monzer Al Sakka, Miguel Dhaens, Christophe Lauwerys
