Abstract:
1. A vibration plate for soil compaction, comprising: an oscillation exciter having at least one unbalanced mass that is driven rotationally about at least one unbalanced axis in order to produce a non-directional oscillation; a soil contact plate that is excited by the oscillation exciter; a transmission device that connects the unbalanced mass to the soil contact plate in order to transmit the oscillation to the soil contact plate; wherein through the transmission device, non-directional oscillation from the unbalanced mass is capable of being converted into an essentially directional oscillation, modifiable with regard to its direction and/or intensity, for the soil contact plate; wherein the direction and/or the intensity of the directional oscillation is capable of being modified during operation by an operating element or a control device; wherein the transmission device has at least two connection devices situated in a transmission path of the oscillation from the unbalanced mass to the soil contact plate; wherein the stiffness of at least one of the connection devices is independent of the stiffness of the other connection device; and wherein the modification of the stiffness of the one connection device relative to a spatial direction can be accomplished by pivoting the one connection device about the axis of rotation of the unbalanced mass.
