摘要:
The present invention relates to devices and to a method for protection against guiding loss for a guided vehicle provided with a guide member including two V-mounted guide rollers (1, 2), i.e. a first roller (1) and a second roller (2), which are to engage with a first rolling surface (7A) and a second rolling surface (7B) of a guide rail (3), respectively, said first and second rolling surfaces (7A, 7B) being located on either side of a longitudinal median plane (M) of said guide rail (3), each of the rollers being provided with a flange (10), said flanges (10) freely clamping onto the guide rail (3), wherein the protection devices include: a profile member (72) having a height h>0 extending longitudinally and being configured to be attached along the length thereof onto at least a portion of said guide rail (3) between said first and second rolling surfaces (7A, 7B), said profile member (72) having a section suitable for guiding the guide member upon a derailment or guiding loss of said guide member when said profile member (72) is attached to said portion of the guide rail (3), wherein said section has a shape suitable for retaining the flange (10) of the first roller (1) on the side of the median plane (M) that includes the rolling surface (7A) of said first roller (1), and the flange (10) of the second roller (2) on the side of the median plane (M) including the rolling surface (7B) of said second roller (2); and a means (73) for attaching said profile member onto said guide rail (3).
摘要:
A method and apparatus for constructing railways for a rubber-wheeled AGT system are provided. The method includes forming guideways, along which guide rollers of a light rail vehicle moves when the light rail vehicle runs along railways and forming, using a pressing unit of a finisher, the railways applied with concrete such that the railways have a same trace as the guideways by moving a finisher along the guideways. The apparatus includes a vehicle that is provided with rollers to run along guideways installed on vertical walls of a road bed and a pressing unit that is disposed under the vehicle to make lateral and longitudinal traces of railways correspond to lateral and longitudinal traces of the guideways by pressing and forming a top surface of railway concrete during the running along the guideways.

The invention concerns a guide rail comprising above the tie pad of its core (3) a railhead (4) formed by two cambered convex flanks (5) and (6) whereof the top parts form upper ramps (13) and (14) serving as running track for inclined guide rollers and assembled by a linking zone (8). Said upper ramps are extended downwards by curved surfaces (12) and (13) followed by lower ramps (15) and (16). The guide rail comprises in certain places engaging-releasing zones formed by opposite slots (21) and (22) in the form of an indentation towards the core (3) central portion for example a linear recess of the curve of each flank so as to allow a guide roller shoulder or stub to pass without materially spacing or modifying the inclination. Said invention is of interest to rail producers and manufacturers of rail-guided road vehicles.

The rail (1) has an upper section (8) used for the guide rollers and a base (3) used for fixing to the ground or on a support. On the zone located between the base and the upper section at least one inclined ramp rising towards the upper section is provided for the rolling of at least one guide roller (7). The invention is applicable in the field of urban public transport above the ground.
摘要:
An electrical power supply and guidance assembly for a wheeled vehicle, consisting of a raisable and pivotable guide member supporting at least one pair of guide wheels which together define a V shape and engage the central web of the rail, said rail being a guiding profile section used as a track. Covering portions forming a linear closure protect the space containing the conductors. Opening means enable the contact portion(s) to pass through and along the closure to collect the supply current and automatically close said closure. Said assembly is particularly suitable for electrically powered urban wheeled transport.
