A soil compacting device has a damping system which couples an upper mass and a lower mass together with a spring system in a vibration system. The damping properties of the damping system can be modified while the device is in operation. Therefore, when the soil compacting device passes over soils having different properties, it can constantly be adjusted in an optimal manner to the ground underneath it by acting on the vibration properties of the overall vibration system.

Soil compacting device with adjustable vibration properties

A vibration generator for generating directed vibrations in a compacting device includes a housing and a first and second flyweight shafts rotatably supported in the housing and extending parallel at a distance to one another. The flyweight shafts have a respective flyweight connected thereto. A first and second intermediate shafts are rotatably supported in the housing and extend parallel to and between the first and second flyweight shafts. Gear wheels positive-lockingly connect the first and second intermediate shafts to one another, the first intermediate shaft to the first flyweight shaft, and the second intermediate shaft to the second flyweight shaft. In this manner, the first intermediate shaft and the first flyweight shaft, respectively, the second intermediate shaft and the second flyweight shaft rotate in opposite directions. One of the intermediate shafts has connected thereto two gear wheels, with one being coupled to the first flyweight shaft and another coupled to the second flyweight shaft. A rotational drive for driving the first and second flyweight shafts so as to rotate in opposite directions with identical rpm is provided. A phase-adjusting mechanism changes in a controlled manner the phase angle between the first and second flyweight shafts by adjusting the angular position of one of the two gear wheels relative to the second intermediate shaft in a controlled manner during operation of the vibration generator.
