Definitions
- the present invention relates to a method and a system for controlling a correct braking of a guided vehicle, as well as an electric switch dedicated to this function, according to the preambles of claims 1, 6 and 13.
- the invention relates to the detection and control of the correct or incorrect braking of a guide member of a guided vehicle.
- Guided vehicle refers to means of public transport such as buses, trolleybuses, trams, subways, trains or train units, etc., but also to means of transporting loads such as, for example, cranes, for which the security aspect is very impor ⁇ so much and for which the guidance is provided in particular by a single rail.
- the latter serves as a guide for a guide member of the guided vehicle, said guide member generally taking support on the rail and following its path during the movement of the guided vehicle.
- the guide member allows for example a guide system to direct es ⁇ sieu Director of the vehicle guided along the path defined by the rail, said axle being for example provided with load wheels.
- a first known variant of the guide member comprises a pair of guide wheels, also called guide rollers, each provided with a lug and mounted in V - ie the rolling surfaces of said wheels are inclined one by one. relative to each other so as to form a V, the axis of rotation of one of said wheels forming a protruding angle with the axis of rotating the other of said wheels - in order to grip the guide rail in the jaw formed by said rollers equipped with their lugs.
- Such a guide member is for example described in US Pat. No. 7,228,803 B2, US Pat. No. 6,029,579 A1, US Pat. No. 6,363,860 B1, WO 2008/074942 A1.
- Such a guiding member securely guards the guidance of the vehicle until it stops. It allows for example to avoid damage that could result from a loss of guidance, and preser ⁇ ver the staff body or passenger embar- c in the case of public transport.
- FIG. 1 shows a pair of rollers 1, 2 mounted in a V of a guiding member known to man. of career.
- the pair of rollers 1, 2, 3 frames a rail with which it is in con tact ⁇ forced and thus the guide member to follow a tra ⁇ jectory defined by the 3 and consequently imposed rail to the steering axle of the guided vehicle cooperating with said guiding organ.
- the guide rail is particularly ⁇ com posed of a plate 4 fixed to the floor 5 and a core 6 supporting a poppet 7 on which the rollers 1, 2 are supported via a tread band 9.
- Each of the rollers 1, 2 of the same pair of guide rollers and has its tread 9 in contact with a surface of the mushroom 7, called rolling surface 8 and distributed symmetrically on either side of the upper part of the mushroom 7.
- Each of the rollers com ⁇ additionally has a lug 10 extending, in nomi ⁇ nal position, under the mushroom 7 of said rail 3 and for freely clamping said mushroom 7.
- the correct orientation of the vehicle is thus obtained by LYING range of the pair of rollers of the guide member with the ⁇ es sieu steering the vehicle. If the rollers enclose correct ⁇ the guide rail, the vehicle follows the path ⁇ finished by the rail during its displacement. On the other hand, if the rollers come out of their normal or nominal operating position, for example, if the guide rail mushroom comes out of the area between the treads and the chins, then the vehicle may leave the trajec. ⁇ tory initially established by the rail (see Fig. 2). Ef ⁇ fet, as soon as the rollers are no longer subject to the direction imposed by the guide rail, they can go to the right or the left of the rail, thereby deflecting the vehicle of the intended track.
- the scenario in question is defined as a loss of guidance or simply deguidage of the vehicle. In other words, the correct positioning of the rollers is a necessary condition to ensure the correct direction of the vehicle.
- a second variation of the guide member is described in WO 2008/074942 Al and consists of a pair of ga ⁇ lets enclosing a fungus, as described above, but with the difference that the rollers are free from net menton- .
- the flanges of the wheels are replaced by fixed and integral flanges to a fixing base of the rollers, the latter being further protected by a bou ⁇ clier safety.
- This configuration provides higher rigidity which increases the effort required for the gates to exit the rail.
- the extraction of the mushroom out of the grip of the rollers is possible. This is the case, for example, when an upward upward pulling force is applied to the rollers or to a base for fixing the rollers so that deformation of the parts (latch and / or mushroom and / or axis of the rollers) make the distance between the chin ⁇ net exceeds the width of the mushroom.
- the ga- threads no longer grip the rail and can be positioned co ⁇ side of the latter, as shown in FIG 2, the refe ⁇ references used in Figure 1 being 2 times to FIG.
- At least one zone of said workshop is equipped with a guide rail 3 without a mushroom (see the core 61 of said rail 3 in FIG 3) and dedicated to the lifting of ⁇ said vehicles.
- This rail is characterized in that the width C of its upper part is smaller than the distance between the ends of the two lugs 101, 201 of the rollers of the guide member.
- the guide member may be li ⁇ Bowski the constraint of rerailing resulting from the geo- sorting of the mushroom and rollers and it is therefore possible to lift the vehicle in a vertical direction to carry out maintenance operations without the rail remains embedded between the guide rollers.
- the vehicle At the end of the maintenance operation, the vehicle is decreased to nou ⁇ calf on its raceway and the rollers meet the position shown in Figure 3.
- the guide rail At the end of the region of the ⁇ husbandry, the guide rail contains its shape provided with said cham ⁇ pinion 7 after a so-called transition zone.
- controlling the correct braking of the guide rollers of a guided vehicle is an important step to guarantee the safe operation of said guided vehicle.
- This control is always carried out in manual mode, also in the case of automatic vehicles.
- devices or methods for detecting either the transition from a status to a derailed condition of a guided vehicle eg, WO 2011/012176
- a presence of the rail eg, WO 2011/012176
- An objective of the present invention is to provide a simple automation, safe and reliable control of the whole okay raillement pebbles on a guide rail, par ⁇ ticular in the workshop, and independent of the presence or ab sence ⁇ mushroom on said rail.

- each electric switch ⁇ stick being configured to mechanically interact or in a free contact with said part of a guide member of the guided vehicle;
- each of said electric switches is connected between the input terminal A and the output terminal B so that a value of a braking signal measurable at the output terminal B changes from a nominal value to a transient value if and only if each switch passes from said first second state audit, each of said switches being in particular initially in the same state in the absence of said interaction, ie all are open or all closed, and conversely, said signaling system is configured so that said value of said signal rerailing measurable at the output terminal B then returns to said initial value when at least one of the switches re ⁇ rotates to said first state, ledi t scrap signal- ment being preferably intended to flow from A to B.
