Abstract
The invention relates to a soil compacting device comprising a motion detection device for detecting an actual value for the travelling motion of the soil compacting device. Inside a travel control device, the actual value is compared with a set value that is predetermined by the operator. When a difference between these two values is determined, the travel control device corrects the travelling motion by controlling a steering device or a drive of the soil compacting device. In another embodiment of the invention, a number of vibration plates are connected by the means of connecting elements to form a soil compacting system, which is also provided with a travel control device. The travel control device controls the individual drives in order to steer the entire soil compacting system.
Claims22
A driveable ground-compaction device, comprising:
- a drive for the generation of a propulsive movement;
- a steering device for the generation of a yawing moment about a vertical axis of the ground-compaction device;
- a travel transmitter to enable a desired value for a travel movement of the ground-compaction device to be specified by an operator;
- a movement detection device for the purpose of detecting an actual value of the travel movement;
- and having
- a travel control device, which can be influenced by the actual value and the desired value, for the purpose of actuating the steering device and/or the drive so as to minimize a control deviation which is formed by the difference between the actual value and the desired value.
A ground-compaction system, having several driveable, mutually connected ground-compaction devices, wherein
- at least one of the ground-compaction devices comprises a drive for the generation of a propulsive movement into a direction of propulsion, and comprises an oscillation excitation device;
- the drive can be switched on and off;
- a travel transmitter is provided to enable a desired value for a travel movement of the entire ground-compaction system to be specified by an operator;
- a movement detection device is provided for the purpose of detecting an actual value for the travel movement;
- and wherein
- a travel control device which can be influenced by the actual value and the desired value is provided for the purpose of actuating the individual drives so as to minimize a control deviation which is formed by the difference between the actual value and the desired value.
