Abstract
An air spring system for a motor vehicle includes essentially a flexible member ( ) having first and second ends. At a first end, the flexible member is closed off by the cover plate ( ) as a connecting part and, at its second end, by a roll-off piston ( ) as a second connecting part. To carry out a contactless distance measurement in accordance with the pulse/echo method in the interior space ( ) of the air spring ( ), an ultrasonic transmitter/receiver ( ) is mounted on one of the two connecting parts ( ) and a reflector ( ) is provided on the other one of the two connecting parts ( ). A separate reference reflector ( ) is not used in order to simplify the construction and to save mounting space for the components. Instead, the reflector is configured as a two-step reflector. The one step functions as a target reflector ( ) and the other step ( ) functions as a reference reflector. A bumper ( ) is preferably configured as a two-step target reflector ( ). The step, which is configured in the bumper ( ) is realized as a blind bore ( ).
