摘要： A state monitoring device of a railcar includes: a monitoring sensor configured to detect state information pieces of a machine part of a bogie; and a wireless transmission unit configured to wirelessly transmit signals at a transmission interval, the signals containing the state information pieces detected by the monitoring sensor. When it is determined that a monitored value based on the state information piece is not more than a threshold, the wireless transmission unit wirelessly transmits the signals at the transmission interval that is a predetermined initial interval. When it is determined that the monitored value has exceeded the threshold, the wireless transmission unit wirelessly transmits the signals at the transmission interval that is a narrow interval narrower than the initial interval.

摘要： A flexible gear coupling includes two external gears and two internal gears meshing with the respective two external gears. A tooth root crowning radius of each external gear is smaller than a tooth tip crowning radius of the external gear. The external gear is formed such that a reference tooth height that is a tooth height at a tooth width direction middle position is smaller than an end tooth height that is a tooth height at a tooth width direction end position. A ratio of the end tooth height to the reference tooth height is set to 1.21 or more, and/or a ratio Rc/Rb of the tooth root crowning radius to the tooth tip crowning radius is set to 0.37 or less.

摘要： A railcar steering bogie includes a bogie frame, a wheelset, an axle box suspension, a steering mechanism configured to steer the wheelset, a brake unit, and a brake unit support link. The brake unit includes: a main body frame; a brake shoe supported by the main body frame and pressed against a wheel tread of the wheel during braking. The brake unit support link couples the axle box suspension and the brake unit and transmits displacement of the axle box in a car longitudinal direction to the brake unit at least during steering performed by the steering mechanism. The brake unit support link restricts the brake unit from being displaced outward in a car width direction by a predetermined distance or more during the braking. At least one of a side surface of the brake unit support link and a side surface of the brake unit includes a sliding surface.
