An ultrasonic measuring device for determining motion parameters of moved bodies, in particular path, speed, acceleration, slip and the like, comprising first and second ultrasonic transducers supported in a housing. Each of the ultrasonic transducers (transmitter and receiver) having either a sound generator or a sound receiver positioned between two vibrating elements. A connecting element clamps a sound generator with a sound receiver between the vibrating elements. Each of the ultrasonic transducers being supported by support elements featuring bent-off portions arranged in a meander-type manner in turn (bent back upon itself) in the housing. One of the support elements, for each transducer, is arranged at the sound opening of the housing and is slidably mounted on a vibrating element.

The measuring apparatus is intended for the automatic measurement of speed, travelled distance and directional changes, wherein two measuring units (3, 3a) are disposed in spaced relationship on the underside (4) of a vehicle (5). Upon a comparison of the left-hand and the right-hand signal a measurement of the directional change is effected, wherein each measuring unit (3, 3a) respectively comprises a forwardly and a backwardly measuring and transmitting measuring section (I and II, respectively); thereby errors of measurement caused by pitching motions of the vehicle may be minimized to less than 0.1%.
