IDENTIFICATION DEVICE FOR A PNEUMATIC SPRING

摘要

The invention relates to an identification device (1) for a pneumatic spring (2) comprising an RFID transponder (8), which is completely embedded into the elastomer matrix (13) of the bellows (4). An electromagnetic field can be generated by a read device (9), wherein the energy necessary for supplying the RFID transponders (8) may be 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 any internal energy supply. The RFID transponder (8) may also be configured as a read/write transponder comprising 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.
