As shown in fig. 3 and 6, a coil case 2 having a substantially cylindrical box shape is provided inside a hub case 1 having a substantially cylindrical box shape. The hub box 1 is formed by fixing a lid 1b to an opening of a bottomed cylindrical container 1a with bolts 8. The coil case 2 is formed by fixing a lid portion 2b to an opening portion of a bottomed cylindrical case 2a with a bolt 9. A bearing 3 is provided at a contact portion between the hub box 1 and the axle 4, so that the hub box 1 rotates together with the tire. The axle 4 is not rotated but fixed to the vehicle body. The coil box 2 is connected and fixed to the axle 4. The power generation coils 5 are disposed at equally divided positions in the circumferential direction as much as possible inside the coil box 2 (see fig. 4 and 5).

The axle 4 is rotatably fitted to a member in which the electrode (N pole 6, S pole 7) is provided at a circumferentially equally-divided position on the outer peripheral portion of the electrode sensing disk 11 in the wheel house 1. The electrode induction disk 11 rotates about the axle 4. In the first embodiment, the electrodes (the N-pole 6 and the S-pole 7) are disposed radially inward of the power generation coil 5.

As shown in fig. 3 and 6, a gear A, B, C, D is provided in the hub box 1 as an example of a member that increases the speed and transmits the rotation of the axle. The gear a is connected to the hub box 1 via the connecting cylindrical portion 13 so as to rotate the axle 4 as a shaft, and rotates at the same speed as the hub box 1. Gear B meshes with gear a. Although not shown, the gear B and the gear C are integrally connected to each other, and are provided on a gear rotation shaft E provided between the lid portion 2B of the coil housing 2 and the gear fixing metal fitting 12 so that the gear B and the gear C rotate at the same speed. The gear C is provided to mesh with the gear D, and the gear D is connected to the electrode sensing plate 11 via the connecting cylindrical portion 14. The electrode induction disk 11 and the gear D rotate at the same speed around the axle 4. When the axle 4 moves, the wheel hub box 1 rotates about the axle 4 together with the tire. The rotation of the gear a rotating at the same speed as the hub box 1 is transmitted to the gear B, C, D at an increased speed, so that the electrode sensing disk 11 rotates at a high speed. Thereby, the electrodes (the N-pole 6 and the S-pole 7) rotate relatively to the power generation coil 5 at a high speed, and power is generated by the power generation coil 5. The electric power output from the power generation coil 5 can be supplied to the outside, stored in a battery, and used as power of an engine motor. In order to improve the performance of the wheel power generation system, the number of the power generation coils 5 may be increased, or the number of the gears and the number of teeth of the gears may be increased or decreased, thereby improving the performance.

The coil box 2 is connected and fixed to the axle 4. The power generation coils 5 are disposed at equally divided positions in the circumferential direction as much as possible inside the coil box 2 (see fig. 4 and 5).

The axle 4 is rotatably fitted to a member in which the electrode (N pole 6, S pole 7) is provided at a circumferentially equally-divided position on the outer peripheral portion of the electrode sensing disk 11 in the wheel house 1. In the second embodiment, as shown in fig. 9 and 12, a cylindrical spacer 11b is fixed to the outer periphery of the small disk portion 11a by screwing, and an annular disk portion 11c is fixed to the tip end portion of the spacer 11b by screwing, thereby forming the electrode sensing disk 11. The electrodes (the N-pole 6 and the S-pole 7) are fixed to the annular disk 11c so as to face the power generation coil 5 in the axial direction of the shaft 4. The motor-responsive disc 11 rotates about the axle 4.

The gear C is provided to mesh with the gear D, and the gear D is connected to the small disk portion 11a of the electrode sensing disk 11 via the coupling cylindrical portion 14. The electrode induction disk 11 and the gear D rotate at the same speed around the axle 4. When the axle 4 moves, the wheel hub box 1 rotates about the axle 4 together with the tire. The rotation of the gear a rotating at the same speed as the hub box 1 is transmitted to the gear B, C, D at an increased speed, and the electrode sensing disk 11 rotates at a high speed. Thereby, the electrodes (the N-pole 6 and the S-pole 7) rotate relatively to the power generation coil 5 at a high speed, and power is generated by the power generation coil 5. The electric power output from the power generation coil 5 can be supplied to the outside, stored in a battery, and used as power of an engine motor. In order to improve the performance of the wheel power generation system, the number of the power generation coils 5 may be increased, or the number of the gears and the number of teeth of the gears may be increased or decreased, thereby improving the performance.
