Patent number: 10703158Abstract: Air spring strut for a motor vehicle including an air spring with a shock absorber for spring-cushioning and damping oscillations of a motor vehicle running gear assembly. The air spring includes an air spring cover and an air spring piston. An air spring bellows made of elastomeric material is clamped air-tightly between the air spring cover and the air spring piston partially delimits a working space filled with compressed air and, while forming a rolling fold, rolls on the air spring cover and/or the air spring piston. The air spring cover is embodied in two parts with a first cover part for receiving an absorber bearing and with a second cover part for fastening the air spring bellows. The first cover part is manufactured from metal and the second cover part is manufactured from plastic.Type: GrantFiled: March 27, 2017Date of Patent: July 7, 2020Assignee: Continental Teves AG & Co. oHGInventors: Ralf Pielock, Andreas Nessel, Susanne Tatter, Christian Schallmeier, Garrett Mark Pniewski, Sunny Makkar, Kranti Kiran Manga

Patent number: 9895777Abstract: An air spring for air suspension system comprises a piston assembly and a damper assembly where the piston assembly is spaced apart from the damper assembly to at least partially define an air chamber. A seal is molded with piston walls to form an integrated piston assembly. The seal includes at least one sealing lip extending radially inward from the piston assembly at an angle that is non-perpendicular to an axis of the damper and the at least one sealing lip contacts the damper assembly when the piston assembly and the damper assembly are assembled together to seal the air chamber.Type: GrantFiled: October 12, 2015Date of Patent: February 20, 2018Assignee: Continental Automotive Systems, Inc.Inventors: Christian Schallmeier, Ralf Pielock, Sunny Makkar, Garrett Mark Pniewski

Publication number: 20160107496Abstract: An air spring for vehicles, having an air spring bellows clamped in an air-tight manner between an air spring cover and an air spring rolling piston. The air spring bellows is made of a composite material consisting of an elastomer material having on or more embedded reinforcing layers, which bellows, along with the air spring cover and the air spring rolling piston, delimits a working chamber filed with compressed air and, by forming a rolling fold, rolls over the air spring rolling piston. The air spring bellows includes a first air spring bellows section and a second air spring bellows section joined together in an overlap region and having reinforcing layers running at a different angle to a longitudinal axis L of the air spring. The first and second air spring bellows sections are separated by a freely movable clamp joint arranged in the overlap region.Type: ApplicationFiled: May 23, 2014Publication date: April 21, 2016Applicant: Continental Teves AG & Co. oHGInventor: Ralf Pielock

Patent number: 8973932Abstract: 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: GrantFiled: October 2, 2012Date of Patent: March 10, 2015Assignee: Continental Teves AG & Co. oHGInventor: Ralf Pielock
