Abstract: The invention relates to an aerial power supply assembly (1) hinged on a fixed base (2) and including a fixed portion and a mobile or deformable portion (5) comprising friction members (9) for supplying electrical power to a vehicle (4) through an upper collecting structure (11) on the roof of the vehicle when passing or stopping under said aerial power supply. The friction members are not powered when the power supply assembly (1) is in a rest position, and are powered when the power supply assembly (1) or the mobile or deformable portion (5) thereof is moved by the arrival of the front part of the upper collecting structure (11) of the vehicle under the power supply assembly (1) that contacts the friction members (9) so as to transfer electrical power to the vehicle. After the passage of the vehicle, the mobile portion of the power supply assembly (1) automatically returns to the rest position in which the friction members are not powered.

Abstract: A support including a rail (10) that preferably has an I-shaped section and is provided in a slot (2) filled with concrete (4). During the manufacture of the rail, the rail is partially coated, substantially along its entire length, with a filler material (8) which defines at least one side extension (16) and bears on the concrete. A side groove (9) is formed in the coating of filler material (8) for the passage of a guiding or rolling wheel. The rail is directly maintained by the concrete such that an intermediate device, for additional maintenance of the rail, is not required. The rail can be bent and curved at the time of installation to conform to the curves of the track without any independent or additional bending step.

Abstract: The guidance system comprises two guidance devices (16) mounted in opposite directions either side of the axle (2) and each comprising: a guidance arm (17) terminated by at least one guidance roller (18); a set of articulated connecting rods serving as a deformable link interface (23) between the axle and the guidance arm; and a jack (29) with two independent and opposing rods (30, 31), having a “rods extended” position in which its two rods lock the set of connecting rods to render it rigid and orient the axle, and a “rods retracted” position in which the set of connecting rods is free and allows a lateral oscillation. Preferably, the jack (29) offers an additional function for damping the lateral oscillation. This invention is of interest in the field of the guidance of public transport road vehicles by a rail.

Abstract: The invention relates to an anti-extraction safety device comprising, for each roller (13, 14), a rotatably fixed, preferably enveloping, shroud element (32, 33) forming a one-piece functional mechanical assembly with its counterpart. The base of the shroud elements has an extension (46, 47) which extends beneath the projecting flanks (21, 22) of the head of the guiding rail (19) in order to prevent any extraction of the guide assembly. At the front, the base of the shroud elements is preferably shaped as a lip for collecting and disposing of objects which may be present on the guiding track. The invention can be used for the 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.
