A track includes a travel path including a travel face with which travel wheels of a vehicle come into contact while rolling. The travel path includes a plurality of travel path forming units that are arranged to be adjacent to each other in a travel direction of the vehicle and of which each includes a unit travel face forming part of the travel face and a positioning unit that fixes a relative position between travel path forming units adjacent to each other.

Track, travel path forming unit, track laying method, and track maintenance method

An anomaly determination device includes a changeover force measurement unit that measures a changeover force output by a driving device, the driving device outputting a changeover force for switching a direction of a branch rail whose direction is variable, a voltage measurement unit that measures a voltage supplied to the driving device, a current measurement unit that measures a current flowing through the driving device, and an anomaly determination unit that determines whether or not there is an anomaly in the branch rail, there is an anomaly in the driving device, and there is an anomaly in power supplied to the driving device on the basis of the magnitude of the changeover force, the magnitude of the voltage, and the magnitude of the current.

Anomaly determination device, anomaly determination method, and program

A traveling bogie includes a steerable wheel, a bogie main body configured to support the steerable wheel, a guide apparatus pivotally supported by the bogie main body and turned by receiving a reaction force from a guide rail, a steering mechanism configured to apply a steering force to the steerable wheel using the reaction force received by the guide apparatus, and an assist mechanism configured to apply an auxiliary steering force for assisting with the steering force from the steering mechanism to the steerable wheel.

Traveling bogie and track-type vehicle

A traffic system includes: a vehicle having a power-receiving section on an outer surface thereof; and a ground facility having a power-supply section for supplying the power-receiving section with power by coming in contact with the power-receiving section. The power-supply section has a spring for applying a biasing force to a power-supply shoe in the power-supply section toward the power-receiving section. The power-receiving section has a flat surface that extends along the outer surface of the vehicle, and tapered surfaces that are connected to the flat surface in the forward and backward moving directions of the vehicle and guide the power-supply shoe to the flat surface against the biasing force to bring the power-supply shoe into contact with the flat surface when the vehicle moves backward and forward.

Traffic system and power supply method

This traveling bogie is provided with: steered wheels; a main body for supporting the steered wheels; a guide device turning when subjected to a reaction force from a guide rail; a steering mechanism for applying a steering force to the steered wheels utilizing the reaction force applied to the guide device; and an assist mechanism for applying an assist steering force to the steered wheels, the assist steering force assisting the steering force applied by the steering mechanism. The assist mechanism is provided with: a first operation arm pivoting together with the steered wheels in the direction in which the steered wheels are steered; a second operation arm rotating about a rotation axis relative to the main body in response to the turning of the guide device; and an elastically deformable section connected to the first operation arm and the second operation arm and elastically deformable.

Bogie and track-type vehicle

In an insulating section, a power feeding rail, and a track transportation system, the insulating section extending along a travel direction of a vehicle and connecting electric train lines coming into contact with a pantograph of the vehicle at a contact surface facing the vehicle is characterized by including: a main surface portion formed on a surface which follows a current-conducting surface coming into contact with the pantograph in the electric train line, and having a portion in which a width in an up-down direction orthogonal to the travel direction is larger than the width of the pantograph; and inclined surface portions provided on both sides in the up-down direction on at least the near side in the travel direction of the main surface portion, inclined so as to gradually approach the vehicle as it goes toward the far side from the near side in the travel direction, and connected to the main surface portion.

Insulating section, power feeding rail, and track transportation system

A main line movable rail is disposed between a near-side main line rail and a forward-side main line rail which are disposed as a center guide rail so as to sandwich a branching section. The main line movable rail is supported so as to swing at the center of a first end at a position at which the first end is continuous to the forward-side main line rail. A locking action mechanism allows a second end of the main line movable rail to be engaged with an engagement member, thereby locking the second end so as not to undergo displacement at a guide position at which the second end of the main line movable rail is continuous to the near-side main line rail.

Branching device and center guide-type track-based transportation system

The present invention provides a bogie for a guide rail type vehicle that runs along a predetermined guideway. The bogie includes a turn frame connected to a vehicle body; an axle turnably mounted to the turn frame via bearings and; a guide frame mounted to the axle; a first pair of guide wheels rotatably provided at a vehicle body end side portion of the guide frame; a second pair of guide wheels rotatably provided at a vehicle body center side portion of the guide frame; a stopper provided so as to project from an upper surface on a vehicle body side of the axle toward the vehicle body; and a pair of stopper receivers arranged facing each other at intervals from the stopper in a vehicle lateral direction.

Bogie for guide rail type vehicle

Provided is a branching device (D), which includes a branch line side guide rail () that is disposed from a near side main line travel track (Ra) to a branch line travel track (Rc) at an inner side of these travel tracks, a main line side guide rail () that is disposed from the near side main line travel track (Ra) to a far side main line travel track (Rb) at an outer side of these travel tracks, and a switching mechanism () that switches a position of a movable rail () of the branch line side guide rail () and a position of a movable rail () of the main line side guide rail () to a branch line guide position (BP) and a main line guide position (MP).

Branching device and track transportation system

A track-guided vehicle wheel truck prevents wear and deterioration of a guide wheel and a guide rail, and ensures running stability while simplifying the structure. In the track-guided vehicle wheel truck, a guide frameto which a guide wheelguided by a guide railis mounted, can turn relative to a steering axleof a running wheel. A support shaftis provided on an axle bracketprovided in the steering axleso as to be movable in the vehicle front and rear direction by straddling the steering axle. A link levercapable of interlocking the turning of the guide frameand the steering of the running wheelis provided along the vehicle front and rear direction. A vehicle end-side end part of the link leveris rotatably mounted to a connecting rodthat enables the steering of the running wheel. An intermediate part of the link leveris rotatably mounted to the guide frame. A long holeextending in the vehicle front and rear direction is provided in a center-side end part of the link lever. The long holeand the support shaftare rotatably engaged with each other at a given position.
