Vibration exciter for construction machines
A vibration exciter for construction machines, particularly for vibration pile drivers, includes at least one axle having at least two imbalance masses. At least one rotary piston pivot motor is provided, by way of which the rotational position of at least one imbalance mass, relative to the at least one other imbalance mass, can be changed. The rotary piston pivot motor has a pivot motor housing that is mounted on a pivot motor shaft so as to rotate relative to it. At least one rotary vane is disposed on the pivot motor shaft, the angle of rotation of which vane is limited by at least one stop disposed on the pivot motor housing. The maximal angle of rotation of the at least one rotary vane amounts to less than 160 degrees, preferably 150 degrees or less.
