A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.

Diagnosis system and diagnosis method for opening/closing device

This invention is equipped with: a steering shaft provided to an underframe of a carbody of a vehicle travelling on a traveling road surface of tracks; king pins provided as a pair to end sections of the steering shaft at both sides in the width direction; axle hubs swingably provided to the steering shaft via the king pins; tires mounted plurally to each of the axle hubs; guide wheels, which roll over guide rails provided to the tracks in the direction of extension of the tracks, and which are guided from the width direction of the tracks; a guide device part for supporting the guide wheels and the steering shaft; and a steering mechanism for causing the axle hubs to turn about the king pins in accordance with the displacement of the guide device part.

Steering bogie, and vehicle for track-based transportation system

A steering bogie provided with a pair of tires () positioned on both sides in the vehicle-widthwise direction, a primary suspension mechanism () for supporting the pair of tires () independent from a subframe (), and a steering guide device () which is guided along guide rails () extending along a track (), wherein the steering guide device () is equipped with: a guide frame (); guide wheels () which roll as a result of contact with the guide rails (), and are rotatably supported by the guide frame (); and a guide frame support mechanism () for supporting the guide frame () by hanging from the primary suspension mechanism ().

Steering bogie and vehicle

A vehicular suspension device has: a pair of primary support parts for respectively and elastically supporting elastic tires on a sub frame, the tires being located on both vehicle-widthwise sides; and a secondary support part for integrally and elastically supporting the pair of primary support parts and a car body via the sub frame, the secondary support part being located between the sub frame and the car body.

A transportation system includes a vehicle, a track having a traveling road surface on which the vehicle travels and guide parts which extend to both sides in a width direction of the traveling road surface. The track has a first section in which the vehicle is guided by the guide parts and travels on the track, and a second section in which the vehicle travels on the track by steering of the vehicle.

Transportation system

In a track type protection system comprising an automatic steering mechanism and a fail-safe mechanism, provided is a detection mechanism which can detect a deviated value of a vehicle, widthwise of a track, and which is highly reliable. The track type transportation system in which the vehicle runs on the road surface of the track, comprising the steering mechanism for automatically steering the front and rear wheels of the vehicle by means of actuators, and the fail-safe mechanism composed of a protection track defined on the road surface of the track, and protection wheels provided in the lower part of the vehicle and adapted to run in the protection track without making contact with the protection track, wherein there are provided a pair of noncontact type displacement meterswhich are attached to a support bracketsuspended downward from the lower part of the vehicle body, and which are arranged in the protection trackso as to irradiate detection waves a onto the left and right side wallsof the protection track, thereby the distances from the noncontact type displacement metersto the left and right side walls of the protection track are measured by the pair of noncontact type displacement meters.

Track type transportation system

Structure for mounting batteries in a guideway electric vehicle driven by a battery-driven motor is provided, with which balancing in weight of the vehicle is properly achieved, batteries can be cooled enough, battery rooms are completely sealed from the passenger room, and running stability of the vehicle is ensured. The battery mounting structure is composed such that battery rooms () for mounting battery modules () comprised of a plurality of batteries are formed on a floor () of the vehicle in both sides adjacent side walls () of the vehicle respectively, each of the battery rooms () being partitioned from the passenger cabin of the vehicle hermetically by a partition plate (); suction openings () for introducing outside air into the battery room () are provided in the floor () or side wall () of the vehicle in each battery room (), and exhaust openings () for releasing air to the outside of the vehicle are provided in the side wall () thereof in each battery room (); whereby the battery module () in each battery room () can be cooled by outside air.

Guideway electric vehicle mounted with batteries

According to a steering control method, before starting, a pattern steering angle table on which pattern steering angles for the front and rear wheels at respective change points of the track are listed is prepared in view of a track condition, etc. from a departure point to a destination point, a vehicle is steered in accordance with a pattern steering angle read from the table, a track widthwise position of the vehicle on running is detected so as to calculate correcting steering angles by which the track widthwise position of the vehicle coincides with a desired position, and the correcting steering angles are added to pattern steering angles so as to obtain desired steering angles by which the front wheels are steered. The pattern steering angle, the corrected steering angle and the desired steering angle are calculated for each of the front and rear wheels, independent from each other.
