Abstract
The invention is directed to an arrangement for making contactless distance measurements within an air spring of a motor vehicle. With the invention, it is unnecessary to modify the longitudinal support of the motor vehicle for the purpose of integrating an ultrasonic distance measuring device. The arrangement includes a transmitter/receiver component (16) which is fixedly mounted to the chassis and is mounted within the air spring (2) laterally next to the support (10) of the vehicle, that is, the transmitter/receiver component is mounted elastically off-center in a tubular stub (14) arranged as part of the cover plate (4). A reflector component (24) is fixedly mounted on the axle and assigned to the transmitter/receiver component (16). The reflector component (24) is mounted on the roll-off piston (8) and includes a lens-shaped convex surface (26) having a surface normal (28) directed toward the transmitter/receiver component (16).
