ELECTRIC POWER GENERATOR THAT CAN BE COUPLED TO A WHEEL AXLE OF A RAIL VEHICLE

The invention relates to an electric POWER generator that can be coupled to a wheel axle (1) of a rail vehicle, which comprises a rotor (2) configured to be disposed such that it receives a rotation of the wheel axle (1), and a stator (3) configured to be disposed radially surrounding the outside of the rotor (2). The rotor (2) comprises two portions (2.1, 2.2) that can be joined together forming a first cylindrical form, and the stator (3) comprises two fractions (3.1, 3.2) that can be joined together forming a second cylindrical form. The generator can thus be positioned and removed with respect to the wheel axle (1) by means of direct access to same. Generador de energía eléctrica acoplable a un eje de ruedas (1) de un vehículo ferroviario, que comprende un rotor (2) configurado para estar dispuesto de forma que recibe un giro del eje de ruedas (1) y un estator (3) configurado para estar dispuesto envolviendo radial y externamente el rotor (2). El rotor (2) comprende dos porciones (2.1, 2.2) unibles entre sí formando una primera forma cilíndrica y el estator (3) comprende dos fracciones (3.1, 3.2) unibles entre sí formando una segunda forma cilíndrica. De esta forma, el generador es colocable y retirable con respecto al eje de ruedas (1) mediante un acceso directo al mismo.
