摘要： PROBLEM TO BE SOLVED: To provide a method for analyzing a factor in an outer rail derailment coefficient where the factor in the outer rail derailment coefficient can be easily analyzed.SOLUTION: The outer rail derailment coefficient is described with a linear sum having a plurality of factors with a factor related to a trajectory curvature in a curve section and a factor related to a difference between an outer rail wheel weight and an inner rail wheel weight of a vehicle (factor setting step). The plurality of factors are described by a measurement value or a setting value related to a track or the vehicle, and multiplied by an unknown coefficient. After the factor setting step, the unknown coefficient is determined so that a difference between the measured outer rail derailment coefficient and the linear sum is minimum (coefficient determination step).

摘要： PROBLEM TO BE SOLVED: To reduce the maximum lateral force of an outside rail wheel of the two axle truck for a railway vehicle in the curve passage, and prevent the deterioration of safety more than a conventional truck in the inside rail wheel.SOLUTION: A single shaft steering truck is provided for steering only a wheel set at the rear side in the traveling direction of the two axle truck. A steering amount incremental rate with respect to a theoretical amount of steering in the case where an amount of steering represented by β/{sin(a sinα/L)}×100 of a steering gear for steering the wheel set in the curve passage (β is a steering angle of the wheel set, (a) is a wheel base, α is a bogie angle (relative angle between the truck and the vehicle body in the curve), and L is a center distance between trucks) is 100% is adjusted in a range of -14% or more and 44% or less. In the single shaft steering truck for railroad steering only the rear axle, the lateral force acting on the outside rail wheel in the curve running is reduced and the occurrence of derailment possibility of the inside rail wheel can be avoided, and thereby the safety in the curve passage is improved.

摘要： PROBLEM TO BE SOLVED: To continue to support a vehicle body by preventing separation between a bogie frame and a wheel set, even when a steering gear of a steering bogie performing the longitudinal support of a steering axle only by a steering mechanism ruptures.SOLUTION: The steering bogie 11 for rolling stock includes an axle box supporting device of a steering axle 2, which performs the vehicle-traveling-direction longitudinal support of each axle box 4 for rotatably supporting the steering axle 2, by the steering gear 3 in which a steering link 2a rotatably connected to the axle box 4 and a connection link 3c rotatably connected to a bolster 7 are each rotatably connected to a steering lever 3b rotatably connected to a bogie frame 6. When the forward and backward movement of the axle box 4 exceeds a forward and backward movement range in maximum steering during passage through a minimum curve, stoppers 12 abutting on the axle box 4 of the steering axle 2 are installed on both the sides of expansion and contraction of a wheelbase in the bogie frame 6. Since an attack angle between a wheel and a rail can be suppressed to be equivalent to an attack angle for a normal bogie even when the steering gear ruptures, safety on the occurrence of a rupture in the steering gear is enhanced.

摘要： PROBLEM TO BE SOLVED: To properly bear a vertical load of a vehicle body while following rotation of an axle box during steering.SOLUTION: In a steering bogie 11, a wheel set 2 of the bogie is steerably configured. A coiled spring 12, which is installed between a bogie frame 5 and each of the axle boxes 1 attached to both ends of the wheel set 2 via bearings and which supports the bogie frame 5, secures the amount of contraction which prevents intimate contact even in the rotation of the axle box during the steering, in addition to the amount of contraction in the case of maximum loading in a straight section. Since the intimate contact of the coiled spring is prevented even during the steering, the transmission of the vertical load of the coiled spring and the axle box portion does not become nonuniform during the steering.
