Publication number: 20220134834Abstract: A vehicle suspension system includes a gas spring. The gas spring includes a cylinder and a rod movable relative to the cylinder. The rod and the cylinder at least partially define a chamber having a variable volume and containing a first pressurized gas therein. The gas spring further includes an accumulator in communication with the chamber and containing a second pressurized gas therein. The gas spring provides a first spring rate when the first pressurized gas is pressurized below a threshold pressure and a second spring rate when the first pressurized gas is pressurized above the threshold pressure.Type: ApplicationFiled: January 14, 2022Publication date: May 5, 2022Applicant: Oshkosh Defense, LLCInventors: Roy Venton-Walters, Aaron J.

Patent number: 11225119Abstract: A vehicle has a vehicle body and a vehicle suspension system supporting the vehicle body. The vehicle suspension has a gas spring, and includes a cylinder, a rod, and an accumulator. The cylinder has a longitudinal axis. The rod is partially disposed within the cylinder and is movable relative to the cylinder along the longitudinal axis of the cylinder. The rod and cylinder together at least partially define a chamber having a variable volume that receives a first pressurized gas. The accumulator is in communication with the chamber and contains a second pressurized gas held at a threshold pressure creating a first spring rate opposing relative movement between the rod and cylinder when the first pressurized gas within the chamber is pressurized below the threshold pressure and a second spring rate when the first pressurized gas within the chamber is pressurized above the threshold pressure.Type: GrantFiled: July 18, 2019Date of Patent: January 18, 2022Assignee: Oshkosh Defense, LLCInventors: Roy Venton-Walters, Aaron J. Rositch, Jesse L. Knoble, Erik S. Ellifson, Mark L. Steckling

Patent number: 11225120Abstract: A vehicle includes a body, a pair of front gas springs coupling a pair of front wheel end assemblies to the body, and a pair of rear gas springs coupling a pair of rear wheel end assemblies to the body. At least one of the rear gas springs includes a cylinder, a rod extending within the cylinder and movable relative to the cylinder, the rod and the cylinder together at least partially defining a chamber having a variable volume and receiving a first pressurized gas therein, and an accumulator in communication with the chamber and containing a second pressurized gas therein. The second pressurized gas within the accumulator is held at a threshold pressure creating a first spring rate when the first pressurized gas is below the threshold pressure and a second spring rate when the first pressurized gas is above the threshold pressure.Type: GrantFiled: August 31, 2021Date of Patent: January 18, 2022Assignee: Oshkosh Defense, LLCInventors: Roy Venton-Walters, Aaron J.

Patent number: 10421332Abstract: A gas spring for a vehicle suspension system includes a cylinder, a rod disposed within the cylinder, the rod and the cylinder at least partially defining a chamber, and an accumulator in communication with the chamber. The rod and the cylinder are configured such that a relative movement therebetween changes the volume of the chamber. Gas in the chamber and the accumulator are configured to cooperate to at least partially provide a spring rate that varies based on at least one of a deflection and a spring force associated with at least one of the rod and the cylinder.Type: GrantFiled: June 23, 2017Date of Patent: September 24, 2019Assignee: Oshkosh Defense, LLCInventors: Roy Venton-Walters, Aaron J.
