Abstract: An unbalance exciter for a vibratory plate includes a rotatably mounted unbalance shaft, on which an unbalance mass is provided. The exciter includes an exciter housing for the unbalance shaft, at least two bearing devices for the rotatable mounting of the unbalance shaft, and two bearing seats for the bearing devices. The exciter housing has a central part and two end parts arranged at the ends of the central part. The central part has a hollow-cylindrical recess in which a bearing point is provided for each of the bearing devices. The the central part is designed to optionally accommodate an unbalance shaft for either a first drive type in which the unbalance exciter can be driven by a drive device provided outside the exciter housing, or a second drive type in which the unbalance exciter can be driven by a drive device provided inside the exciter housing.

Abstract: A vibratory plate for soil compaction machine has an upper mass and a lower mass that is elastically coupled to the upper mass and that has a soil contact plate. The soil contact plate has a vibration exciter device. At least one energy storage element is situated on the upper mass.

Abstract: A vibrating plate comprises a vibration generator device, which can be controlled in such a manner that the direction of the action of force can be set at a number of locations, particularly in more than two locations. In addition, an advance adjusting device is provided for controlling the vibration generator device whereby the direction of the action of force is set in a position in which a maximum possible advance of the vibrating plate is reached. The direction of the action of force can be changed according to a change in the surroundings of the vibrating plate, particularly to the slope and/or the hardness of a subsoil to be compacted by a soil contact plate. Alternatively, the direction of the action of force can be changed according to the wishes of the operator.
