    "Modular framework for a public passenger-carrying land vehicle and vehicle comprising such a framework"
    The present invention relates to a modular frame for a public passenger transport ground vehicle, in particular of the bus or tram-bus type. It also relates to a land passenger public transport vehicle comprising such a frame.
    The field of the invention is the field of public transport land vehicles, including electric vehicles, bus, bus or tram-bus.
    State of the art
    One of the most popular means of public transport is the bus, because its implementation does not require specific infrastructure, such as railway track for example. To further reduce pollution related to public transport, electric buses are emerging, encouraged not only by the awareness of users but also by administrative incentives encouraging the purchase and use of electric vehicles. We are also witnessing the appearance and development of tram-buses. Thus, the number of buses, electric or not, is constantly increasing.
    The current buses are built by assembling many pieces forming ultimately the frame of the bus which is the main element of the bus. The frame is then dressed, then equipped. The bus is built as and when, by adding pieces, such as bars or tubes, individually one after the other. The attachment of an individual part to others is done by bolting or welding.
    This technique of building a bus has various disadvantages. First, bus manufacturing is not optimized on an industrial scale, because as long as a first frame is not completed, it is not possible to start a second frame, without occupying a significant space . In addition, such manufacture is not flexible at the geographical location, because it requires to build the entire frame on the same site. In addition, it is necessary to fix parts at height, at the ceiling of the bus, which is not ergonomic and presents a risk of injury to operators. Moreover, when it is necessary to apply a treatment, for example of the cataphoresis type, to the framework, such treatment requires treatment facilities, for example cataphoresis baths, of specific dimensions, which sometimes do not exist. not even in the country of manufacture.
    An object of the present invention is to overcome these disadvantages.
    Another object of the invention is to provide a skeleton for public transport land vehicle more flexible to manufacture on an industrial level.
    Another object of the invention is to provide a skeleton for public transport land vehicle more ergonomic and less dangerous to manufacture for operators.
    It is also an object of the invention to provide a frame for a public transport land vehicle, not requiring specific size installations during their manufacture, especially when applying a treatment to said frame.
    DESCRIPTION OF THE INVENTION The invention makes it possible to achieve at least one of these objects by a framework for a public passenger transport land vehicle, in particular of the bus type, characterized in that it is formed by assembly, between them, at least two independent modules, previously manufactured.
    Thus, the invention proposes to manufacture a frame by assembling modules independent of each other. Each of the modules composing the frame can be manufactured independently of the other modules.
    Therefore, the invention proposes a skeleton for a public transit vehicle that is more flexible to manufacture in terms of manufacturing sites, since the modules can be manufactured and then assembled on the same site or on at least two different sites. In addition, the frame according to the invention is more flexible to manufacture in time, because the modules can be manufactured at the same time or in a staggered manner, in advance, etc.
    In addition, each module having dimensions smaller than those of a complete frame, they are more ergonomic and less dangerous to manufacture for operators. For example, it is possible to provide a module corresponding to the ceiling of the frame that can be made at ground level, which presents less danger to operators.
    In addition, each module having dimensions smaller than those of a complete frame, their treatment can be fast while not requiring specific size installations, especially when applying a treatment, cataphoresis type.
    In addition, the modular design of the frame according to the invention makes it easier and faster to modify a part of the vehicle, such as, for example, the front of the vehicle for left-hand or right-hand drive, a side wall of the vehicle. to add or delete an opening, etc., the remaining modules remain unchanged.
    Another advantage of the invention is that each module can be made on a steerable preparation station / returnable so that each welding operation, bolting or dressing can be performed arm height operators.
    Yet another advantage is to be able to produce almost complete modules in parallel with each other by dressing them separately before final assembly of the modules with each other. An almost finished vehicle is thus obtained very quickly.
    In the present application, "module" means an assembly comprising at least half, preferably 75%, of a wall of the vehicle frame.
    In the present application, a "tram-bus" designates a terrestrial public transport vehicle mounted on wheels and which recharges at each station, so as not to require heavy rail-type infrastructures, catenaries, on the road. Such an electric vehicle is recharged at each station by means of load elements of the station and a connector connecting said vehicle to said station.
    Advantageously, the framework may be composed of a total number of modules less than or equal to 5, and in particular less than or equal to 4, and even more particularly less than or equal to 3.
    Preferably, the framework according to the invention can comprise exactly three or four modules.
    Such a number of modules allows an advantageous ratio between production time of each module and assembly time of the modules together to form the frame, while preserving the advantages described above relating to ergonomics, modularity, ease of processing, etc.
    In a non-limiting embodiment, the frame according to the invention may comprise a so-called upper module, comprising an upper wall and, optionally, the upper part of at least one, in particular each, of two longitudinal side walls. on at least a portion, in particular all, of the length of said frame.
    Such an upper module makes it possible to design the upper wall of the frame at an adequate working height, without assistance of a specific tool for turning the entire framework or without having to work at the total height of the frame. framework, as is the case with current techniques.
    Moreover, with such an upper module it is possible to modify the upper wall in a modular manner, without having to modify the other modules.
    In a non-limiting embodiment, the frame according to the invention may comprise a module, said to be lower, comprising a bottom wall and, optionally, the bottom part of at least one, in particular of each, of two longitudinal side walls. on at least a portion, in particular all, of the length of said frame.
    With such a lower module, it is possible to modify in a modular way the lower wall of the frame, without having to modify the other modules.
    In a preferred embodiment, the frame may comprise: - an upper module comprising the upper part of each of the two longitudinal side walls, and - a lower module comprising the lower part of each, of the two longitudinal side walls.
    According to this preferred embodiment, the longitudinal division of the framework between the upper module and the lower module is located at each of the longitudinal side walls, that is to say at a zone of least effort, and not at the level of the junctions between on the one hand the side walls and on the other hand the upper and lower walls, which constitute areas where the mechanical forces are concentrated.
    In particular: the upper module may comprise the upper part of each of the two longitudinal side walls, and the lower module may comprise the remainder of each of the two longitudinal side walls; on at least a part, in particular the whole, of the length of said framework, so that by assembling the lower module with the upper module, the longitudinal side walls are formed on at least a part, in particular the whole, of the length of said frame.
    Such an architecture allows a longitudinal cut, between the upper and lower modules, at an upper portion of each of the longitudinal side walls, and a fixing of the upper module on the lower module. Thus, the assembly of the upper and lower modules is facilitated because there is no other module between the upper module and the lower module.
    Preferably, the frame may have a longitudinal cut, between the upper module and the lower module, in a horizontal plane so that said cut is made at the same height for each of the longitudinal side walls.
    Such a feature makes it possible to increase the modularity of the frame and to be able to use interchangeably a plurality of upper modules with a plurality of lower modules.
    Advantageously, the upper module, respectively the lower module, may have a vertical plane of symmetry passing through the center of the upper wall, respectively of the lower wall, in the width direction of said frame.
    Thus, the upper module, respectively lower, can be used in one direction or another, which reduces errors during assembly of the frame.
    In a non-limiting embodiment, the frame according to the invention may comprise a module, said before, comprising a front wall and, optionally, a portion of at least one of the longitudinal side walls, upper or lower of said frame.
    Such a front module allows a more ergonomic design to manufacture because it can be manufactured flat. In addition, it is possible to design different versions of a front module and use them interchangeably to customize, on the fly and on request, the frame according to the invention.
    In particular, the front module may comprise a part of each of the longitudinal side walls, upper or lower of said frame and in particular on a length such that said front module comprises the cockpit.
    Such a front module closes, at the front, the frame according to the invention along a cutting plane avoiding areas most mechanically stressed. In addition, such a front module can further customize the frame according to the invention, for example by proposing on the fly a cockpit right or left.
    In a non-limiting embodiment, the frame according to the invention may comprise a module, said rear, having a rear wall and, optionally, a portion of at least one of the longitudinal side walls, upper or lower of said frame.
    Such a rear module allows a more ergonomic design to manufacture because it can be manufactured flat. In addition, it is possible to design different versions of a rear module and use them interchangeably to customize, on the fly and on request, the frame according to the invention.
    In particular, the rear module may comprise a portion of each of the longitudinal side walls, upper or lower of said frame.
    Such a rear module is closed at the rear, the frame according to the invention along a cutting plane avoiding areas most mechanically stressed. In addition, such a rear module makes it possible to further personalize the frame according to the invention, for example by proposing on the fly a rear module comprising an engine location and / or an air-conditioning location and / or a location for batteries, etc.
    In a preferred embodiment, the frame may have a vertical cut, in a plane substantially perpendicular to: - the longitudinal side walls, - the upper wall and / or the lower wall; between the front module, respectively the rear module, and the remainder of said frame.
    Such cutting allows for simple design of the frame and front and rear modules easily interchangeable
    According to the invention, at least two modules can be assembled together by welding, in particular by stainless welding, and / or by bolting.
    When at least two modules are assembled by welding, in particular by stainless welding, at least one, in particular each, module may have at least one stainless steel welding interface.
