Patent number: 9833947Abstract: An identification device (1) for a pneumatic spring (2) includes an RFID transponder (8), which is completely embedded into the elastomer matrix (13) of the flexible member (4). An electromagnetic field is generated by a read device (9), wherein the energy necessary for supplying the RFID transponder (8) is taken from the electromagnetic field generated by the read device (9). When the read device (9) is active, information can be exchanged between the RFID transponder (8) and the read device (9). The RFID transponder (8) operates completely without an internal energy supply. The RFID transponder (8) may also be configured as a read/write transponder including a memory chip, wherein data may be stored on the memory chip in a safe and permanent manner. By retrieving data from the RFID transponder (8), an identification of the pneumatic spring (2) is possible even without any internal power supply of the RFID transponder.Type: GrantFiled: October 14, 2014Date of Patent: December 5, 2017Assignee: ContiTech Luftfedersysteme GmbHInventors: Siegfried Reck, Hubertus Gawinski

Patent number: 8220785Abstract: A flexible member air spring has an end section of the flexible member attached to a connecting part by a clamp ring. The connecting part has a slot having a truncated cone-shaped cross section. The base of the slot is cylindrical and a flank of the slot has a linear conical form. The inner surface of the clamp ring extends parallel to the base surface. In the clamped state, the inner radius of the clamp ring is less than or equal to at least one of the radii of the slot upper edges. The flexible member is not compressed between the base surface of the slot and the inner side of the clamp ring. The clamp ring, with at least one slot flank, forms a constriction clamping the flexible member wall of the end section.Type: GrantFiled: October 7, 2005Date of Patent: July 17, 2012Assignee: ContiTech Luftfedersteme GmbHInventors: Christoph Bank, Paul Cerny, Hubertus Gawinski

Patent number: 7361007Abstract: Tubular-shaped flexible members for air springs are made of rubber or rubber-like elastomers and are reinforced by reinforcement layers. In order that the air spring flexible member can roll telescopically off a roll-off piston, the tubular-shaped flexible member sections must be brought into a slightly conical or bottle-like configuration and then vulcanized in this form. A method forms and vulcanizes an air spring flexible member blank and utilizes an apparatus which includes a mold defining a bellied inner wall defining a common hollow space for receiving the air spring flexible member blank therein. A pressure bellows unit includes a pressure bellows extending axially in the common hollow space as well as first and second end pieces joined to the pressure bellows at corresponding longitudinal ends thereof.Type: GrantFiled: September 28, 2005Date of Patent: April 22, 2008Assignee: ContiTech Luftfedersysteme GmbHInventors: Christoph Bederna, Hubertus Gawinski

Patent number: 5509641Abstract: The invention is directed to an air spring which supports a vehicle body on another vibrating component with an air spring flexible member which can be charged with pressurized air. The ends of the air spring flexible member are mounted air tight on respective connecting parts. One of the connecting parts is mounted on the vehicle body and the other connecting part is mounted on a vehicle component. The connecting part mounted on the vehicle component includes an elastically tied vibration absorber mass in order to reduce vibrations of the vehicle component in the resonant region.Type: GrantFiled: December 15, 1994Date of Patent: April 23, 1996Assignee: Continental AktiengesellschaftInventors: Hubertus Prinzler, Hubertus Gawinski

Patent number: 5180146Abstract: During a shock absorbing movement a rolling crease of a roll bellows is supported at the outer mantle surface of a wall of a pot-shaped rolling piston in an arrangement for a roll bellows-type pneumatic shock absorber. In order to provide a rolling piston with a high stiffness and a low total weight the wall is provided with stiffening corrugations which are essentially extending in a longitudinal direction of the rolling piston. Due to the stiffening corrugations high loads exerted by the rolling crease and any maximum load peaks occurring during the dynamic operation of the pneumatic shock absorber may be securely received and compensated by the rolling piston.Type: GrantFiled: March 15, 1991Date of Patent: January 19, 1993Assignee: Continental AktiengesellschaftInventors: Eckhard Schneider, Hubertus Gawinski
