Air spring arrangement having a device for making ultrasonic distance measurements therein |
摘要 |
The invention is directed to an air spring arrangement having a device for making ultrasonic distance measurements. An ultrasonic sensor, which is built into an air spring (2) for making measurements, can be disturbed when high frequency sonic oscillations occur when filling and venting the air spring. An air supply line (8) is disposed between the air spring (2) and a source of compressed air (30). To prevent the above disturbing frequencies, the air supply line (8) includes an air connecting pipe stub (10) which is lined with a net-shaped layer (16) on its inner wall surface. The layer (16) is preferably a plastic mesh. The filaments (18) of the mesh-shaped layer (16) are slightly inclined to the longitudinal center axis (28) of the pipe stub (10).
