Abstract
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.
Claims16
A soil compacting device with
- an upper mass (1);
- a lower mass (3) for soil compaction;
- a spring system (2) coupling the upper mass and the lower mass;
- and with
- a damper system (4), which is arranged between the upper mass and the lower mass and interacts with the spring system;
- a control system that actively varies damping properties of the damper system (4) during operation of the device.
