Railway carriage has battery charging voltage generator formed by electromagnetic coil and iron body mounted on wheel or axle to distort magnetic rotational symmetry of wheel or axle

摘要

The carriage has an electrical load supplied with current by a battery (11) rechargeable by a charger (10) and a voltage generator driven by a carriage wheel (2) or axle (3). The generator consists of an electromagnetic coil (5) and an iron body (7) mounted on the wheel or axle that distorts the magnetic rotational symmetry of the wheel or axle and is not in contact with the coil. The coil is connected to the battery via a rectifier and charger.
