Device for contactless distance measurement

摘要

The device has an ultrasonic arrangement consisting of a chassis mounted transmission/reception component (16) and an axle-mounted reflector component (24). The transmission/reception component is mounted off-centre. The reflector surface (26) of the reflector component, which is mounted on the axis of symmetry (30) of the pneumatic spring (2), is convex and points towards the transmission/reception component (16).
