Description

GUIDE RAIL FOR AUTOMOTIVE VEHICLE OF THE TYPE AÜTOGUIA The invention relates to a guide rail intended for urban passenger transport. Due to the limited terrain in the cities, and especially in the center of the old cities, the municipalities have the tendency to prefer for the transport of surface, the types of guided public transports. These types of transport ensure a minimum impression on the ground especially in the turns. These include the trams, but now also the automotive vehicles guided by more or less complex guidance systems that mostly use a guide rail that serves as a bearing track to the roller (s) of the steering organ. The cities already equipped with public surface transport on rails or autoguided self-guided can not consider changing infrastructure due to heavy investments that they have often already made. The invention provides a positive solution to this desire to use the existing structures for other types of means of transport, and in particular the use of automotive means of transport guided by the ground.

German patent DE 195 07 880 filed on behalf of the Friedrich REMMERT company on March 7, 1995 with internal priority of March 23, 1994, is a system of guided travel on a rail. This system is intended for different maintenance applications, especially by moving one or several frames. According to this system, a truck 1 carrying a post 5 of a mobile assembly moves in a guided manner along a rail 2 by means of carrier wheels 9. These carrier wheels roll on the top table of the rail. They support the weight of the truck and its load. Two pairs of guide rollers (10, 11), one forward, one rearward, located on one side and the other of the carrier wheel roll on adjacent tracks formed by the sidewalls of the rail. The carrier wheels are thus framed by four rolling and lateral supports that ensure the carriage guidance. The object of this invention is the bearing-guide on the same rail of a heavy rolling assembly to ensure a good lateral stability. The top table of the rail does not serve as a guide but only and exclusively of bearing, this bearing is guided simultaneously by the support rollers on the lateral tracks.

Thus the bearing is inseparably associated with the guide on the same rail used by means of four rollers used in pairs distant from each other and on one side and another of the carrier wheel which thus constitutes a carriage of great lateral stability. The present invention provides public transport systems for people who use at least one guide rail carrier or not to adapt them to a guidance system of an automotive vehicle that employs a guidance device with one or two rollers inclined roller guide on when except this rail. The object of the invention is therefore to transform the rails which exist to make them suitable for serving as guide rails in another guide system, especially a guide assembly with inclined rollers. The particular object is to return the existing polyvalent rails or using the intermediate zone between the sole and the upper profile to allow a guide through a different system, especially of the type of inclined rollers. For this purpose, the invention relates to a guide rail having an upper bearing profile and a base with a fixing sole for mounting on the ground or on a support characterized in that it is provided on an intermediate zone extending from the profile top of the bearing to the fixing base at least one guide-bearing track of at least one guide roller along the rail. The interest of the invention lies in the following advantages. Modifying the existing rail (s), they become bi or multicompatibles, that is to say apt to be used by one or other guidance systems. The same infrastructure can serve both the original transport system, but also other guidance systems. It can also be suitable for two self-guided means of transport but by means of different directional organs. Above all, it can admit, when it is of the railway type, a common self-guided means of transport of the automotive type. With a unique investment, the guide rail according to the invention makes it possible to ensure compatibility with other rail guidance systems for the future. Classically, the rails use the upper profile to ensure general guidance by bearing. The object of the invention is to return the polyvalent rail using the other zones available for another guide by means of a roller system. A complementary interface is provided in the middle part of the rail to also allow a guide but by a different system. The general inventive idea is to confer a versatility with respect to different guidance systems and this without modifying the upper part of the rail relative to the bearing-guide or the single bearing. Other features and advantages of the invention will appear in the description that follows, given by way of example and accompanied by the drawings that represent: Figure 1 is a straight section of a first guide rail according to the invention with an enlargement on the ramp of guide; Figure 2 is a cross section of a second guide rail with enlargement on the guide ramp; Figures 3 and 4 are cross-sectional views showing the use of the first guide rail respectively with a guide assembly with right roller and with two inclined rollers; Figures 5 and 6 are cross-sectional views showing the use of the second variant of the guide rail according to the invention respectively using the guide-bearing along the rail and with an inclined roller; Figure 7 shows the guide assembly with an inclined roller and the representation to the back of the rim adjacent to the guided vehicle; Figures 8 and 9 are straight sections respectively of a complete assembly with two guide-bearing rails and of a complete assembly of two inclined guide rollers shown in front of the neighboring rim of the guide vehicle. On a guide rail which conventionally has a top profile 1 of a bearing or of a bearing table used for the bearing and a base 2 that forms a support sole 3 for its attachment to the ground 4 or on a flat support is provided on an area intermediate 5 extending from the upper profile 1 to the base 2 when at least one rolling track 6 will stop the rolling displacement of at least one guide roller 7 along the rail. This bearing track 6 is preferentially presented in the form of an inclined ramp 8 made on the rail flank in the intermediate zone 5 defined hereinabove and is in contraction as shown by the shaded areas. This ramp cooperates with an inclined guide roller 7 which forms part of a guide assembly 9 mounted on an automotive vehicle of which a wheel is shown with the rim 10 on Figures 7 and 9. This bearing track can be placed vertically and cooperates with a horizontal roller. It could also be horizontal and cooperate with a vertical roller. Two ways of rail section were represented by way of example. A rail section is distinguished first of which the upper part is conventionally used as a guide with the help of a roller 11 of the pulley type with a square or rectangular profile groove. The side walls of the throat are intended to prevent derailment. The intermediate zone of this guide rail is constituted by the lower part of the fungus that continues from the core. It is notched on each side according to a general shape at corner 12 to form each time the ramp 8 serving as a rolling track for a guide roller 7 which forms part of a specific guide assembly 9 different from it using the upper right roller . The ramp is inclined according to a slope parallel to the axis of the guide roller. The second variant is presented in the general form of a rail 13 with groove 14 used classically for urban railroad transports called trams. It consists of a top of bearing-guide 1 in fungus traditionally called a rolling table used by the wheels or carts 15 of the trams. This mushroom is laterally continued by a linear transverse extension 16 delimiting the longitudinal groove 14 with the mushroom. It continues downwards through a core 17 and the fixing sole 3. According to the invention, the upper part 1 serving as the table for rolling it remains identical when the intermediate part 5 located below the fungus and close to the core 17 is shaped so that it has a contraction 18 having at its lower part the preferably inclined rolling ramp 8 serving as a rolling track for the guide roller 7. These rails are generally used in pairs (Figures 8 and 9). The homologous rail placed in relation is arranged symmetrically with respect to the longitudinal middle axis of the track. It has the same characteristics so as to be able to serve as a bearing track to a symmetrical roller 7 of the same guidance system of an automotive vehicle. The guide rollers of this same guide system are inclined diverging from top to bottom. Each can be integrated into a guide arm that is part of the same assembly. Whichever the guidance system can be considered the use of the upper part of the rail to perform the return of current by means of a friction vehicle integral with the vehicle.
