Vibration exciter for steerable soil compacting devices

A vibration exciter for a ground compaction device, comprising:

• a first imbalance shaft,
• a second imbalance shaft which is arranged axially parallel to the first imbalance shaft and which is coupled to the first imbalance shaft in a positively locking fashion so as to rotate in the opposite direction as the first imbalance shaft, wherein the second imbalance shaft is formed from a first imbalance shaft half and a second imbalance shaft half which is arranged coaxially with respect to the first imbalance shaft half and which is rotatable relative to the first imbalance shaft half,
• a drive device which is configured to drive one of the imbalance shafts in rotation, and
• a coupling device which couples the first imbalance shaft half and the second imbalance shaft half together in a positively locking fashion and so as to be rotatable relative to one another, the coupling device comprising a sleeve having opposed ends into which the first and second imbalance shaft halves and first and second traverse pins are inserted, wherein each of the first and second transverse pins engages the sleeve and a respective one of the first and second imbalance shaft halves;
• wherein
• at least one imbalance mass is arranged on each of the first imbalance shaft, the first imbalance shaft half, and the second imbalance shaft half.
