Abstract:
A device for producing directional vibrations, comprising:at least two centrifugal weights with essentially the same m x r which can be driven in rotation in opposite directions at essentially the same speed about mutually parallel axes of rotation;a largely rigid carrier, on which the centrifugal weights, are rotatably mounted; anda bracket on which the carrier can be mounted in such a way by means of a holder that the carrier can be moved relative to the bracket, the holder having at least one spring element for transmitting the movement of the carrier in the direction of the directional vibration and in a direction perpendicular to the directional vibration and perpendicular to the axes of rotation of the centrifugal weights, whereinthe centrifugal weights can be driven independently of one another andthe stiffness of the spring element is matched to the stiffness of the carrier.
