Abstract:
Provided is a guide device for a rail-guided vehicle that is guided to travel along a travel track, the guide device including: guide wheels that roll in contact with guide rails arranged on both sides of the travel track; steering arms that steer the vehicle; guide wheel support members; and shock-absorbing members. One end of each guide wheel support member is supported at the tip end of a steering arm with shock-absorbing members interposed therebetween, and the other end of each guide wheel support member rollably supports a main guide wheel and a diverging guide wheel. The shock-absorbing members are disposed between each guide wheel support member and the corresponding steering arm, and mitigate the impact load transmitted from the guide wheels to the steering arms.
Abstract:
A system of dynamic control of rolling on at least one guide rail for a guidance system of a vehicle along at least one guide rail, composed of at least one roller or at least one pair of guide rollers rolling along this guide rail, is characterized in that it incorporates a vibrational sensor located near at least one roller or at least one pair of guide rollers and a proximity sensor, and in that the signals transmitted by these sensors, or the circuits in which they are placed, are continually analyzed to establish a commencement of guidance failure, a guidance failure, a limit of wearing of or damage to the roller(s) or their tires. This invention is of interest to manufacturers of vehicles guided along at least one rail.
Abstract:
A guided vehicle includes a guidance unit having first and second V-mounted guide pulleys resting on first and second running surfaces of a guide rail. The running surfaces are on sides of a median longitudinal plane of the guide rail and each pulley has a flange for freely gripping the guide rail. A device and method protecting against loss of vehicle guidance include a section with longitudinal height fixed along its length to a guide rail part, between running surfaces, the section having a cross-section guiding the unit during derailment or loss of guidance thereof with the section fixed to the guide rail part. The cross-section geometry holds the first pulley flange on the side of the median plane including the first pulley running surface and the second pulley flange on the side including the second pulley running surface. A device fixes the section to the guide rail.
Abstract:
The anti-extraction safety system incorporates, on each side, one side component which does not rotate with the corresponding roller, that incorporates at least one inclined flap articulated to pivot between a lowered position wherein its lower part extends under the rail head, and a raised position in which its lower part is laterally distanced from the rail. The pivot axis of the flap is inclined upwards and is located in the rear part of the flap, above the lower part in the lowered position. This flap is subjected to a downward return force which maintains it in the lowered position, but which allows it to pivot to the raised position when an upward force greater than the return force, is applied on its lower part.
Abstract:
A track-guided vehicle wheel truck facilitates vehicle maintenance and enables reduction in costs. The track vehicle wheel truck includes guide frames arranged along the forward and rearward directions of the vehicle on the inside of the vehicle width direction in the running wheels, and fixed to knuckles; a tie rod arranged on the center side of the forward and rearward directions in the vehicle along the vehicle width direction, and interlock with the guide frames; guide wheel receivers disposed toward the inside of the vehicle width direction from the guide frames on the vehicle end side and the center side relative to an axis of the running wheels; and a steering axle arranged along the vehicle width direction, and are able to turn the running wheels, the knuckles, and the guide frames by installing a kingpin at both ends thereof.

Abstract:
A system for guiding a vehicle along a guiding rail includes a guide roller device, with at least one rolling bearing roller and at least one lateral roller having a diameter and shape contacting the rail so that the lateral roller has the same speed at a point of contact with the rail as the central bearing roller on a rolling surface on the rail. The system can be used for tramways.
Abstract:
An anti-extraction safety device having, for each roller (13, 14), a rotationally fixed, preferably enveloping, shroud element (32, 33) forming a single-component functional mechanical set with its counterpart. The shroud parts are inclined and each has an extension (46, 47), at the base, which extends beneath the projecting flanks (21, 22) of the head of the guiding rail (19) to prevent extraction of the guidance set. At the front, the base of the shroud parts is preferably moulded into a spout for collecting and disposing of objects which may be present on the guiding track. The anti-extraction safety device can be used for rail guidance of road vehicles used for public transport.
Abstract:
A sliding body (25) which includes an electrical contact shoe (32) that moves on a guide rail (5) along the length thereof. The sliding body (25) is mounted to the front of a guiding assembly, in the direction of movement of a vehicle, and articulated with the assembly by a connecting rod (26) that is designed to rupture upon exceeding a pre-determined limit. The sliding body (25) includes a device (43), which is located on at least one of the sides of the body, for lifting and releasing objects or debris. The loss of electrical contact between the shoe and the rail enables a risk of derailment to be detected. The invention is suitable for rail-guided vehicle manufactures.
Abstract:
A system for guiding a vehicle along a guiding rail, comprising a guide roller device (1), characterized in that is comprises at least one rolling bearing roller (24) and at least one lateral roller (25, 26) forming the lateral part whereby the diameter thereof and the shape of the lateral surface (51, 52) entering into contact with the rail (2) are selected in such a way that the lateral roller has the same speed at the point of contact (54) thereof with the rail (2) as the central bearing roller (24) on the rolling surface on the rail. The system can be used for tramways, for example
