A soil compaction machine with energy transmission device for supplying a sensor device for the determination of the soil rigidity cb with electrical energy and method for producing and operation

摘要

The invention relates to a compaction machine (1), in particular a soil compaction roller or hand-guided soil compaction machine, with a of a drive means (4) driven shaft (16, 44, 49, 54) and an at least one acceleration sensor (21) comprising a sensor device (19) for the determination of the soil rigidity cb of a ground to be compacted (8), wherein the shaft (16, 44, 49, 54), by means of a radial and / or axial air gap (69) of the sensor device (19) is at a distance that an energy transmission device (65) is present, the contactless energy of the shaft (16, 44, 49, 54) by way of the air gap (69) on the sensor device (19), and in that the supply of electrical energy of the sensor device (19), in particular exclusively by the energy transmission device (65) is transmitted energy. The present invention furthermore relates to a method (32) for the operation of a at least one acceleration sensor (21) comprising a sensor device (19) for the determination of the soil rigidity cb while the soil compacting with a soil compaction machine (1) and a method (56) for the manufacture or retrofitting a compaction machine (1).
