A steering bogie for a railway vehicle is configured so that tread surface cleaning devices are operated only when the railway vehicle passes through a curved section. A steering bogie (11) is configured so that the wheel axles (2) of the bogie can be steered. The steering bogie (11) is provided with tread surface cleaning devices each having: a cleaner (12a) mounted to the bogie frame (1) of the steering bogie (11) at a position facing the tread surface (2aa) of a wheel (2a), the mounting of the cleaner (12a) being such that the cleaner (12a) can come into contact with and be separated from the tread surface (2aa); a pressing-load application spring (12c) for pressing the cleaner (12a) to the wheel tread surface side; and a stopper (12d) for restraining the cleaner (12a) from moving toward and approaching the wheel tread surface, the restraint being such that only the inner track-side cleaners (12a) make contact with the tread surfaces (2aa) of wheels (2a), the inner track-side cleaners (12a) being those to which the tread surfaces (2aa) come near because of the forward and backward movement of the wheel axles (2) in the movement direction of the railway vehicle caused by steering during the passage of the railway vehicle through a curved section, such that the outer track-side cleaners (12a) do not make contact with tread surfaces (2aa) of wheels (2a) during the passage of the railway vehicle through the curved section, the outer track-side cleaners (12a) being those from which the tread surfaces (2aa) of wheels (2a) separate, and such that the cleaners (12a) do not make contact with the tread surfaces (2aa) of the wheels (2a) during the passage of the railway vehicle through a straight section. The wear of the cleaners can be reduced because only the inner track-side cleaners, toward which the tread surfaces of the wheels approach during the passage of the railway vehicle through a curved section, make contact with the wheels. |
