The embodiment of the invention provides a rubber spring, a bogie and a railway vehicle, and the rubber spring comprises a spring body which is internally provided with a cavity; the base is used for fixing the bottom or the outer ring of the spring body; the positioning pin component is fixed at the top or an inner ring of the spring body and is connected with a vehicle framework or a wheel set; the condensation assembly comprises a condensation component, one end of the condensation component is connected with a condensation inlet path and a condensation outlet path of the condensation component, the other end of the condensation inlet path is communicated with one of the top or the bottom of the cavity of the spring body, and the other end of the condensation outlet path is communicated with the other one of the top or the bottom of the cavity of the spring body. And a cooling medium is driven to flow between the condensation assembly and the inner cavity of the spring body for heat exchange. Medium heat in the cavity in the spring body is exchanged, and the rubber spring is cooled, so that the service life of the rubber spring is prolonged.
