摘要： PROBLEM TO BE SOLVED: To provide an abnormality detection method of a vehicle which can not only detect an abnormality of a track but also abnormality of a carriage, with a high precision irrespective of a state of the track, and to provide equipment which is used for executing the method and a vehicle mounting the equipment.
SOLUTION: The abnormality detection method of a vehicle detects vibration of the vehicle, and detects abnormality of the vehicle and the track of the vehicle, on the basis of the detected vibration. The method detects a vibration of both the undercarriage and a wheel shaft of the vehicle (steps S100 and S104), and identifies whether the cause of vibration is in the carriage or the track (steps S102, S106 and S108), on the basis of the detected vibration value of the carriage and the detected vibration value of the wheel shaft.

摘要： PROBLEM TO BE SOLVED: To facilitate removal of an axle assembly from an axle box structure without separating an axle box supporting device and an upper axle box from a carriage frame and without detaching a drop prevention plate or a drop prevention bolt by constructing an axle box body of a two-piece structure consisting of the upper axle box, to which the axle box supporting device is installed, and a lower axle box serving as an axle receiver. SOLUTION: An axle box body 5, which is formed into a cylinder substantially, is split into two pieces vertically in the position below a half position C of its circumference so as to be constructed of a two-piece structure consisting of an upper axle box 6, to which an axle box supporting device 8 is installed, and a lower axle box 7 serving as an axle receiver, while a drop prevention plate 12 is fixed to the lower axle box 7 so that a predetermined slight clearance can be secured between the axle box body 5 and a bearing block 13. In this way, for replacement of a wheel and the like, the lower axle box 7 can be separated from the upper axle box 6 when fastening of a bolt-nut 10 in a flange part F of an axle box structure J is released, and in this process, the drop prevention plate 12 can be also separated integrally with the lower axle box 7. As a result, an axle assembly can be easily separated from the axle box structure J.
