A bogie for a railway vehicle having a bogie frame 22 supported by axle springs 10 disposed on axle boxes 9 which rotatably support a wheel set 7, with air springs 4 disposed on both sides of the railway vehicle in a width direction of the bogie frame, each of the air springs 4 being provided with an automatic height adjusting device 6 for maintaining a constant height of a vehicle body 5 which is supported by the air springs 4.
The axle boxes 9 are disposed at positions closer to the center side of the railway vehicle in the width direction than the wheels 7b attached to both sides of a shaft 7a which constitutes a wheel set 7, and a height detection position of the automatic height adjusting device 6 is detected at a position between an axial center of the air springs 4 and an axial center of the axle springs 10.
It becomes possible to improve the ability to pass through exit easement curve sections.

摘要： OBJECT: To accurately detect a derailment, so as to prevent a railway vehicle from traveling when its wheels have become disengaged from a rail without an operator being aware of it, thus improving safety after the derailment occurs.
MEANS: For example, a transmission line 5 configured to be broken when it comes into contact with a rail 4 is installed on a disengagement prevention guide 1 attached to an axle box 3 of a railway vehicle. One end 5a and the other end 5b of the transmission line 5 are connected to a determination unit 6 to monitor continuity of the transmission line 5. In the event of a derailment, the determination unit 6 determines that a derailment has occurred when the disengagement prevention guide 1 makes contact with the rail 4 and the transmission line 5 breaks, thereby interrupting the continuity of the transmission line 5.

摘要： OBJECT
To operate a tread surface cleaning system only when passing through a curved section. A steering truck 11 is designed to make it possible to steer a wheel axle 2 of a truck.
MEANS
A tread surface cleaning system having a cleaning element 12a mounted to a truck frame 1 of a steering truck 11 in a position facing a tread surface 2aa of a wheel 2a, the cleaning element 12a moving freely to come into contact with and to move away from the tread surface 2aa; a pressing-load application spring 12c which presses on the cleaning element 12a biased toward the tread surface 2aa; and a stopper 12d for restraining the cleaning element 12a from approaching the tread surface 2aa, which utilizes a forward and backward movement of a wheel axle 2 in the travel direction caused by steering, so that the cleaning element 12a makes contact only on the inner rail side toward which the tread surface 2aa of the wheel 2a approaches when passing through a curved section, whereas the cleaning element 12a does not make contact on the outer rail side from which the tread surface 2aa of the wheel 2a moves away when passing through a curved section and when traveling through a straight section. Wear on the cleaning element can be reduced, because only a cleaning element on the inner rail side toward which the wheel tread surface approaches comes into contact with the wheel tread surface when passing through a curved section.

摘要： To prevent separation of a truck frame and a wheel axle and to continue supporting a vehicle, even if damage has occurred to a steering device of a steering truck in which front-back support of a steering axle is performed only by a steering mechanism.
A railway vehicle steering truck 11 provided with an axle box suspension of a steering axle 2, which is designed to perform support in the front-back direction of an axle box 4 which rotatably supports the steering axle 2, by means of a steering device 3 having a steering link 2a which is rotatably connected to the axle box 4, and a connecting link 3c rotatably connected to a bolster 7, each of these being rotatably connected to a steering lever 3b which is rotatably connected to the a truck frame 6.
A stopper 12 to which the axle box 4 comes in contact is installed both on a side where a wheelbase expands and on a side where the wheelbase contracts in the truck frame 6, when a front-back movement of the axle box exceeds a range of front-back movement at a time of maximum steering when the front-back movement of the axle box 4 passes through a minimum curve.

摘要： An inspection apparatus (800) calculates an alignment irregularity amount by substituting angular displacements of wheel sets (13a to 13d) in a yawing direction, state variables derived by a filter, and a measured value of a forward-and-backward-direction force into motion equations that describe yawings of the wheel sets (13a to 13d).
