Ground compaction roller and method for producing an oscillating image of a ground compaction roller

A ground compaction roller, comprising:

• a machine frame having an operator platform,
• a drive engine;
• at least one first roller drum, said at least one first roller drum being mounted for rotation between two mounting arms arranged at face sides of said at least one first roller drum and connected to the machine frame;
• and
• a first exciter unit configured to generate oscillations arranged inside said at least one first roller drum, said first exciter unit comprising:
• an exciter housing;
• two imbalance weights mounted inside said exciter housing for rotation in opposite directions and coupled to one another, said imbalance weights rotating about two rotation axes (R1, R2) that are stationary relative to said exciter housing;
• and
• a drive motor arranged outside said exciter housing, said drive motor being in drive connection with at least one of said two rotatably mounted imbalance weights,
• wherein said exciter housing is rotationally fixed relative to the mounting arms, and that the two imbalance weights are coupled to one another in such a manner that their amplitudes of the two imbalance weights add up in a horizontal direction.
