摘要： PROBLEM TO BE SOLVED: To provide a steering truck for a railway vehicle capable of attaining reduction of lateral pressure during passing through a curve of the truck by assisting steering force by an actuator without active-controlling the actuator.
SOLUTION: The actuator 15 is provided between a truck frame 2 and a steering beam 5, and is provided with an expandable/contactable hydraulic actuator body 18 connected to the truck frame 2 and the steering beam 5; an oil feeding means 19 for assisting expansion/contraction of the actuator body 18 by an oil pressure by feeding an operation oil to the actuator body 18 when the actuator body 18 is expanded/contracted by turning the truck frame 2 relative to the steering beam 5. Therefore, since swinging (turning) of the truck frame 2 is assisted by the actuator 15 and the truck frame 2 is quickly swung (turned) by relatively light force, rotation resistance of the truck (truck frame) 1 is reduced. As a result, the lateral pressure during passing through the curve can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle body inclining device and a vehicle body inclining method capable of accurately controlling inclination of a vehicle body, and to provide a railroad vehicle.
SOLUTION: The vehicle body inclining device 3 for inclining a vehicle body 10 on a bogie 2 is provided with a pendular beam 31 for supporting the vehicle body 10 on the bogie 2, a first actuator 4 for inclining the pendular beam 3 against the bogie 2, a second actuator 5 for inclining the vehicle body 10 against the oscillating beam 31, and a control device 6 for controlling the first actuator 4 and the second actuator 5 based on each of target inclinations by computing a target inclination against the first actuator 4 and the second actuator 5. The second actuator 5 has a pneumatic spring 50 interposed between the pendular beam 31 and the vehicle body 10, and a fluid pump 51 for inclining the vehicle body 10 against the pendular beam 31 by moving operating fluid inside the pneumatic spring 51. The control device 6 performs the control of the second actuator 5 before the control of the first actuator 4 by n seconds in relation to a railroad at the same point.

摘要： PROBLEM TO BE SOLVED: To provide a variable-gage rolling stock bogie that is designed to rotate its left and right pair of wheels integrally with each other through rotation of its axle. SOLUTION: Axle outer cylinders 40R and 40L adapted to slide on an axle 6 rotated by a drive motor 1 rotate integrally with the axle 6 by means of axle adapters 30R and 30L. The outer cylinders 40R and 40L are fitted thereabout with a right and left pair of wheels 60R and 60L, which rotate integrally with the outer cylinders 40R and 40L or the axle 6. The outer cylinders 40R and 40L are further mounted with locking blocks 50R and 50L through tapered roller bearings 45. The blocks 50R and 50L are adapted to engage with axle boxes 20R and 20L at their positions corresponding to the standard or narrow gage to thus hold the outer cylinders 40R and 40L or the axle 6 rotatable.

摘要： PROBLEM TO BE SOLVED: To prevent positively a variable-gage rolling stock bogie from being put into its gage-changeable state owing to the flying motion of its axle box or boxes off its locking block or blocks even if the bogie frame bounds while the vehicle runs in an anomalous portion on a track, and work the bogie completely independent of the ground equipment. SOLUTION: If a bogie frame D moves up from an axle box 10 at least by a predetermined distance, the slant portion 43 and a second vertical wall portion 44 both of a securing-pin actuating means 40 protrude a securing pin into a locking block 20 side to thereby hold the block 20 unable to make relative downward displacement from the box 10. The box 10 is thus hindered from flying off the block 20 and the wheel is held fixed as it is, even if the bogie frame D bounds, so that the gage is never changed over.

摘要： PROBLEM TO BE SOLVED: To change a gauge while the rolling stock is running, and concurrently prevent twisting force from being applied to an axle even when the variable gauge bogie is inclined in the right and left direction. SOLUTION: An axle end pivot 32 is fixedly attached to the end part of a rolling stock axle 6, and a spherical bearing 34 is mounted to the axle end pivot 32. A tapered cylinder 35 is fixedly attached to the spherical bearing 34, and a guide pin 40 is inserted into the tapered cylinder 35 in such a way that it can be slid in the axial direction. The guide pin 40 is fixedly attached to an axle box 4 by way of an upper and a lower bracket 36 and 37. Since the axle box 4 can be rotated with respect to the axle 6 by the spherical bearing 34, even when the variable gauge bogie is inclined in the right and left direction, the right and left axle boxes 4 are revolved with respect to the axle 6, and therefore no twisting force will never be applied to the axle 6.

摘要： PROBLEM TO BE SOLVED: To decrease the friction between an axle box and body support rails in varying the gage of a railcar and prevent the disengagement of the axle box from a locking block during normal traveling of the railcar. SOLUTION: An axle box 20 of a gage-varying carriage moves along body support rails 15 by means of a pair of turning rollers 31 which roll on the body support rails 15. During normal traveling, since a slide block 41 which contacts with a locking block 9 at the bottom thereof is locked by a locking piston 45 on the axle box 20, the axle box 20 is prevented from floating with respect to the locking piston 9 and thus both axle box and locking piston are prevented from disengaging from each other. In varying the gage, on the other hand, a locking-piston push rod 47 pressed upward by the body support rails 15 displaces the locking piston 45 to disengage the slide block 41 from the axle box 20.

摘要： PURPOSE: To provide a gauge-changeable carriage for a rolling stock of high safety and reliability in which gauge change can be performed during run, and in which the occurrence of play in a wheel position lock mechanism can be prevented. CONSTITUTION: Around an axle 6 without rotating, an axle outer cylinder 10 is engaged to be slidable in an axial direction, and a wheel 12 is rotatably supported on the axle outer cylinder 10. A locking block 13 is inserted on an end part of the axle outer cylinder 10, and protrusions 15A, 15B in conical forms are respectively engaged in engagement holes 16 in an axle box 4, when axial move of the axle outer cylinder 10 is locked. Engagement of the conical protrusions 15A, 15B with the engagement holes 16 is performed by the weight of a carriage. A vibration-proofing unit 18 for the protrusions 15A, 15B is installed on the engagement hole 16, and the vibration-proofing unit 18 elastically energizes side surfaces of the protrusions 15A, 15B engaged with the engagement holes 16.

摘要： PROBLEM TO BE SOLVED: To improve safety during high-speed traveling by reducing a load applied on one wheel without increasing the installing number of trucks per one rolling stock. SOLUTION: The truck comprises a truck main body installed on a vehicle main body, a pair of main axles rotation supporting a pair of wheels at front and rear sides of the vehicle main body, and at least one sub axle rotation supporting the pair of the axles between a pair of main axles. The supporting stiffness of the pair of the axles supported by the sub axle is set to be soft in a vehicular width direction rather than the supporting stiffness of the pair of the axles supported by the main axle.
