The invention discloses a power generation device in an axle box and a vehicle axle box. The power generation device in the axle box comprises a stator and a rotor arranged in the middle of the stator, wherein the rotor comprises a rotor framework and a magnetism generation part arranged on the periphery of the rotor framework, the stator comprises a stator framework and a power generation part arranged on the inner periphery of the stator framework, the power generation part is connected with an output wire, and when the rotor rotates, current generated by the power generation part is output along the output wire. According to the power generation device in the axle box, the mature electromagnetic power generation principle is adopted, the technology is mature, reliability is high, and safety is high; power can be supplied to all wireless sensors, and the equipment cost and the installation workload are reduced to the maximum extent; only the output wire from the power generation device to the wireless sensor exists, the number of cable cores and the size of the cable are reduced, and the problem that wiring is difficult when a wired sensor is applied is solved to a certain extent; and the power generation power is high, no strict low power consumption requirement on the wireless sensor exists, and the application limitation on the wireless sensor is less.
