| 摘要 |
The invention relates to a device for inductively transmitting electrical energy to or from a mobile object (3) that is located on a roadway or rail, is at a standstill or in motion, and comprises a load and/or an energy store, comprising a floor inductor (5) that is associated with the roadway (1) and comprises a plurality of first induction coils (4) that are arranged along the roadway (1) or rail, are connected to a current source, and have a magnetically conductive iron core (6) for generating a magnetic field directed toward the moving object (3). An inductive wheel (8) attached to the moving object (3) comprises a stationary second induction coil (9) having a magnetically conductive iron core (10) and magnetically conductive wheel disks (11, 12) that are directed toward the roadway (1) or rail and connected to said magnetically conductive iron core on both sides. Elastic, magnetically conductive tires (13) rotating with the motion of the object (3) are associated with the wheel disks for contacting the roadway (1) and for ensuring a low-loss magnetic flux between the induction coils (4, 9), wherein in the flattened state, said tires securely bridge an air gap between the roadway and wheel disks. The device can be used advantageously in connection with electric vehicles for comfortably and quickly recharging the batteries during driving or parking. |
