摘要： PURPOSE: To realize automatic coupling and release during travel only by adding a little change to the present fixation closed system. CONSTITUTION: A specific section A for automatic coupling and release is set at a train route using a closed method, and a discrimination code ID is given to a train to be conducted with automatic coupling or automatic release, and it is registered at a ground station that the train emitting this discrimination code is a train to be conducted with automatic coupling or automatic release. When the train to be conducted with automatic coupling or automatic release has advanced into the specific section A, a signal to show the discrimination code is transmitted to the ground station, and the ground station decides that the train is the one to be conducted with automatic coupling or automatic release, when it has received the signal to show the discrimination code, and executes automatic coupling action or automatic release action while controlling a relative speed between the preceeding train T1 and the following train T2. Meanwhile, when a train that is not to be conducted with automatic coupling or automatic release has advanced into the specific section A, normal operation control is continued.

摘要： PROBLEM TO BE SOLVED: To enable a change of gage during traveling by arranging an outer rotor shaft in a peripheral surface of one axle, and fixing a wheel device to the outer rotor shaft, and assembling an outer rotor shaft moving mechanism for moving the outer rotor shaft in the axial direction in relation to the axle inside of a carrier. SOLUTION: A cylindrical outer rotor fixed shaft 2 is inserted into a peripheral surface of an axle 1 freely to be slid in the axial direction, and a wheel bearing 3 is installed in a part of the fixed shaft 2, and a wheel 4 is supported by the wheel bearing 3 at an outer wheel side freely to be rotated. An outer rotor end fitting 14 receives the force from a crank shaft link 12 so as to slide on the axle 1 for movement with the outer rotor fixed shaft 2, an outer rotor rotator 5 and the wheel 4. A crank shaft 10 is driven by an electric motor through a flexible joint and a gear mechanism so as to change a gage. With this structure, a train can travel through blocks having a different gage.

摘要： PROBLEM TO BE SOLVED: To perform switch between a broad-gauge track and a narrow-gauge track, whose track gauges are different from each other, during traveling of a rolling stock by rotationally moving either of the/four wheels to either of a narrow-gauge rail or a broad-gauge rail by means of a mechanism by which wheels arranged on the rolling stock side can be moved vertically. SOLUTION: A fixed supporting shaft 1, which is usually not turned at all during travel, is turned by 180 degrees only in a track gauge changing section, so that either of a narrow-gauge wheel 6 or a broad-gauge wheel 10 is lowered below a roadbed so as to support a rolling stock body. On the outside of an eccentric seat 2 installed eccentrically in the middle of the fixed supporting shaft 1, an eccentric shaft 3, which is eccentrically deflected further in the opposite direction, is arranged, while a bearing 5 arranged on the outer circumference side of the eccentric seat 2 is fixed rotationally by means of a hollow supporting shaft 4. In this constitution, a positional relationship between the broad-gauge wheel 10 and the narrow-gauge wheel 6 is reversed when the fixed supporting shaft 1 is turned by 180 degrees and the eccentric condition of the eccentric seat 2 is changed from the upper side one to the lower side one, and as a result, the narrow-gauge wheel 6 can run on a rail 22.

摘要： PROBLEM TO BE SOLVED: To provide a brake which is capable of appropriately using a unit brake into which a slack adjuster function automatically performing a gap adjustment between the tread of a wheel and a brake shoe is incorporated also for a steering truck performing an oscillating steering for a wheel shaft. SOLUTION: Unit brakes 10L and 10R pressing brake shoes 11 on the tread of a wheel 1 mounted on a wheel shaft 2 are mounted on supporting arms 7 and 9 provided on a gear box 3 transmitting driving force to the wheel shaft 2. Namely, because the gear box 3 supported by the wheel shaft 2 moves integrally with the wheel shaft 2, the gap of the wheel shaft 1 and the unit brakes 10L and 10R does not change even if an oscillating steering is performed for the wheel shaft 2. Therefore, the unit brakes 10L and 10R into which slack adjuster functions are incorporated can be applied also to a steering truck.

摘要： PROBLEM TO BE SOLVED: To provide a three-axle steering truck for a rolling stock, capable of giving a high steering performance. SOLUTION: A three-axle steering truck 100 for a rolling stock has a front axle 11 and rear axle 13 mounted so as to be capable of yawing for a truck frame 1, and an intermediate axle 12 capable of yawing for the truck frame 1 as well as laterally movable along the breadthwise direction of a track 2. Also, when the three-axle steering truck 100 moves along the curved part of the track 2, the front axle 11 and the rear axle 13 are made to yaw and steered in such a state as keeping the axial lines S1 and S3 thereof extended to the center O of the curvature of the curved part. Furthermore, an axle spring for elastically supporting the axle boxes of the front and rear axles 11 and 13 on the truck frame 1, is formed to have a small spring constant along the lengthwise direction of the track 2, compared with a spring constant along the breadthwise direction of the track 2. In addition, the second axle spring for elastically supporting the intermediate axle 12 on the truck frame 1 is formed to have a small spring constant along the breadthwise direction of the track 2, compared with a spring constant along the lengthwise direction of the track 2.

摘要： PURPOSE: To prevent respective trucks from being synchronized with current fluctuation and vibrating when numbers of main motors are driven by connecting and restraining respective trucks of a car body and varying the spring constant of a spring mechanism respectively arranged in the proceeding direction between the trucks adjoining in front and rear in the proceeding direction. CONSTITUTION: A center pivot 16 running through the central part of a truck frame 15 hangs down from the bottom of a car body and a lower center pivot fitting 17 is secured to the bottom end of the center pivot 16 rotatably in the oscillating direction, while a bolster anchor 20 is arranged on the right and left sides of the lower center pivot fitting 17. The end part of the bolster anchor 20 and a truck frame seat 18 are provided with a rubber bush and a bush pin, which are fixed to the end part of the bolster anchor 20, inserted and secured thereon. Thus, it is possible to change the spring constant connecting respective trucks 15A, 15B, 15C to a car body 13 if the thickness or the rubber hardness of a rubber bush 22 of the bolster anchor 20 connecting between trucks 15A, 15B, 15C together in the longitudinal direction is changed by respective trucks 15A, 15B, 15C, and it is possible to slide the longitudinal natural vibration of the respective trucks 15A, 15B, 15C with respect to the car body 13.
