Patent number: 8844911Abstract: The invention relates to an air spring having an air spring flexible member (1) whose wall (5) of elastomeric material has at least one reinforcement layer (19) and bead (3) with a reinforcement core. The reinforcement layer surrounds the reinforcement core in the form of a loop (20). The flexible member wall, which projects from the bead, does not lie flush on the piston but forms an arc projecting away from the piston when viewed in cross section. The core loop can thus terminate inside the piston diameter thereby improving the roll-off characteristics of the flexible member.Type: GrantFiled: September 27, 2005Date of Patent: September 30, 2014Assignee: ContiTech Luftfedersysteme GmbHInventors: Axel Szyszka, Matthias Hlawatczek

Patent number: 8844912Abstract: A shock absorber for a vehicle, having a bellows piston, bellows, and a fluid as the damping medium. The shock absorber has a first partition wall, which is situated on the bellows piston, and is implemented to separate a volume area of the bellows piston from a volume area of the bellows. The first partition wall has a first opening, which is implemented to limit a fluid flow between the volume area of the bellows piston and the volume area of the bellows. The shock absorber further has a sprung mass, which is situated inside the shock absorber to influence the fluid flow inside the shock absorber.Type: GrantFiled: April 8, 2009Date of Patent: September 30, 2014Assignee: Knorr-Bremse Systeme fuer Nutzfahrzeuge GmbHInventor: Thomas Naber

Publication number: 20140252743Abstract: An air spring for vehicle undercarriages, including an air spring cover and rolling piston. The air spring cover and rolling piston are connected by an air spring bellows. The air spring cover accommodates a first and second clamping ring for clamping the air spring bellows to fix the air spring bellows to the air spring cover. The rolling piston and air spring bellows have a common first air volume. The end of the rolling piston closest to the undercarriage accommodates a third clamping ring to seal the first air volume from the external environment. The air spring cover has a second air volume. The first air volume and the second air volume are sealed off from the external environment. The first air volume is spatially separated from the second air volume. A switch valve enables a first air path to link the second air volume to the first air volume.Type: ApplicationFiled: October 2, 2012Publication date: September 11, 2014Inventor: Ralf Pielock

Publication number: 20140246818Abstract: A flexible spring member includes a flexible wall that is at least partially formed from an elastomeric material The flexible wall can have a longitudinal axis and extend peripherally about the axis and longitudinally between first and second ends. The flexible wall can also include an outside surface and an inside surface that can at least partially define a spring chamber. A radial-biasing band can be disposed along the outside surface of the flexible wall in longitudinally-spaced relation to the first and second ends. The radial-biasing band can be at least partially formed from an elastomeric material and can be operative to elastically bias at least a portion of the flexible wall in one of a radially-inward direction and a radially-outward direction in an inflated condition of the gas spring assembly. A gas spring assembly and a method of manufacture including such a flexible spring member are also included.Type: ApplicationFiled: February 28, 2014Publication date: September 4, 2014Applicant: Firestone Industrial Products Company, LLCInventor: Jason B.
