Abstract
A wheel has two wheel halves, a generator, two bearings and two metal rings. The wheel halves are detachably connected to each other. The generator is composed of an annular coil seat and an annular permanent magnet. The coil seat is securely mounted between the wheel halves and has a winding wound around the coil seat. The permanent magnet is rotatably mounted between the wheel halves. Each bearing is received in one of the wheel halves and electrically connects with one end of the winding. Each ring is securely attached to one of the wheel halves to abut the bearing. Consequently, the coil seat will rotate with the wheel bodies and relative to the permanent magnet and generate electricity. The electricity will be transmitted to a lighting device or a sounding device. The enjoyment of a roller skate or a skateboard with the wheel is improved.
