<p>A force actuator arrangement comprises a force generating member performing an oscillating movement, preferably a rod (7) of magnetostrictive material, force transmitting means -in a disc brake arrangement a caliper (4, 5)-, and a device (8, 9) for transforming the oscillating movement to a unidirectional application movement of the force transmitting means. The oscillation frequency of the force generating member is higher than the natural frequency of the force transmitting means for enabling the movement transforming device to transmit the movement only during each oscillation stroke in the application direction.</p> |
