    HEAVY REAR MOTOR VEHICLE WITH SUPPORT OF MASS IN SUPPORT
    INDEPENDENT TO CHASSIS
    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION
    The invention, as expressed in the description of the present specification, refers to a heavy rear-engine vehicle with mass distribution in independent support to the chassis that provides, to the function to which it is intended, advantages and characteristics, which will be described. in detail below, which represent a remarkable novelty of the current state of the art.
    More specifically, the object of the invention is focused on a heavy vehicle with rear engine, in particular a coach or bus for the transport of people, which, instead of incorporating said engine and the set of organs associated therewith in The vehicle's own chassis, in an innovative way, incorporates such elements coupled to an independent support to the chassis and that, through suspension elements, is attached to the chassis in front of the differential rear axle, whereby the load is distributed with the axle front avoiding problems arising from overload on the rear axle.
    FIELD OF APPLICATION OF THE INVENTION
    The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of vehicles, focusing particularly on the field of the manufacture of heavy vehicles, transport of people, and more specifically in the manufacture of buses and buses for the transport of passengers.
    BACKGROUND OF THE INVENTION
    As is known, currently all rear-engine vehicles, and especially those concerned here, mount the engine and associated elements incorporated directly on the chassis of the vehicle itself. However, and despite the fact that this is an extended practice and admitted by the administrations that approve said vehicles, in many cases it means speeding up the compliance limit or even directly

    breach of what the legislation itself indicates about the distribution of the weights that must be met.
    Specifically, the Regulation on heavy, priority, special vehicles for transport of people and goods and Administrative Processing, in its 2013 edition and Order pre / 52/2010, of January 21, in its chapter 2 on masses and dimensions, in the point D of its section 2.2 on maximum permissible masses, points out that the circulation of vehicles or vehicle assemblies in which the mass supported by the drive axle or drive axles is less than 25% of the total load mass is not allowed of the vehicle or set of vehicles.
    As can be deduced, this regulation is aimed at ensuring the safety of these vehicles and, therefore, ensuring strict compliance would be desirable in all cases. What happens in most cases is that the verification of the loads is carried out with the vehicle stopped, ignoring its moving behavior, with the vehicle in circulation, which is when the loads really act and their behavior directly affects safety of the vehicle and, consequently of its passengers.
    In certain cases, even the previous overhang of the vehicle is used to compensate the axle loads when the provisions of the aforementioned guideline are not fulfilled even with the vehicle stationary.
    For example, it can be seen with the naked eye how coaches with rear engine, at the exit of a speed bump, the front wheel drive makes it separate considerably from the floor, and by common sense, it follows that at that time on the axle forward does not fall the weight that would correspond. Similarly, with the powerful engines that vehicles usually have today, in quick starts, the front axle suffers the same effect. In both cases this circumstance poses a danger to its stability, since the adhesion on the asphalt is very poor. If it were also the case that the geometry of the coach was not correct, it could be a very unfavorable mixture for the safety of the vehicle, the passengers and a great responsibility for the driver, when this is totally foreign to the responsibility of manufacturing the vehicle.
    The objective of the present invention is therefore to avoid said problem and develop a new type of heavy vehicle in which the distribution of the mass, when the engine is rear, does not

    be supported directly on the chassis of the vehicle to lighten the load of the same on the rear axle and, consequently, ensure that the premise that less than 25% of the total what this axle supports supports is fulfilled.
    On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other heavy rear-engine vehicle or similar invention that has the same technical, structural and constitutive characteristics is unknown. or similar to those presented by the one recommended here, as claimed.
    EXPLANATION OF THE INVENTION
    Thus, the heavy-duty rear-engine vehicle with mass distribution on stand-alone support to the chassis that the invention proposes is configured as a novelty within its field of application, since, being the characterizing details that make it possible and that distinguish it conveniently collected in the final claims that accompany the present description.
    Specifically, what the invention proposes, as noted above, is a heavy vehicle, in particular a coach or bus for the transport of people, with a rear engine that, unlike the vehicles currently on the market, which they incorporate the engine and other organs of the kinematic assembly in the vehicle's own chassis, it incorporates such elements incorporated in a support that, as a frame or sub-chassis, is independent of the vehicle chassis, being configured so that the load they entail The engine of other elements, instead of affecting the rear axle, is divided between both axes.
    To this end, said support is of elongated structure and, at its front end, joins the vehicle chassis articulated and damping at a point of the same anterior to the rear axle, that is, located between the rear axle and the front axle, and, at its rear, also articulately, it joins the last bridge of the vehicle chassis.
    Preferably, the support is incorporated into the chassis suspended by the lower part thereof, since superiorly there is usually no available space and the joints would be more complex, while inferiorly, between the chassis and the ground there can always be

    space.
    In any case, the kinematic motor and gearbox assembly is mounted between the rear axle and the rear end of the support, which, through the transmission, is linked to the rear axle differential.
    The described heavy-duty rear-engine vehicle with mass distribution on stand-alone support to the chassis represents, therefore, an innovation of structural and constitutive characteristics unknown until now, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.
    DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, this descriptive report is attached, as an integral part thereof, of a set of drawings, in which with character Illustrative and not limiting, the following has been represented:
    Figure number 1.- Shows a schematic side elevation view of an example of a conventional rear-engine heavy vehicle, showing the arrangement of the engine coupled to the vehicle's own chassis, according to the prior art.
    Figure number 2.- Shows a schematic side elevation view of an example of the heavy-duty rear-engine vehicle with mass distribution in independent support to the chassis, object of the invention, showing the arrangement of the engine coupled to the independent support that has a such effect.

    Thus, according to said figures, in which the vehicle and its parts have been represented in a very schematic way since the details of construction and configuration are not part of the object of the invention, it can be seen how, heavy vehicles according to the technique front (1 '), with rear engine (2), mount said engine (2) directly coupled to the chassis (3) of the vehicle itself behind the rear axle (4) with the differential, so that the mass thereof determines a load on said axis.
    In the vehicle (1) of the invention, however, the engine (2) is provided incorporated in a support (5) which is an independent element to the chassis (3) of the vehicle itself, which is designed as a frame or "Sub-chassis" that joins articulated to said chassis (3), preferably suspended by the lower part thereof.
    More specifically, said support (5) consists of an elongated structure, which, at its front end (5a) is articulated and cushioned, preferably by means of bellows (6) "torpress" and shock absorber (7), to the chassis (3) at a point before the rear axle (4), thus remaining between it and the front axle (8), and, at its rear (5b), the support (5) is also articulated, in this case preferably by a ball joint (9), to the last bridge of the chassis (3) of the vehicle.
    In any case, the rear area of the support (5), between the rear axle (4) and its rear end (5b), is mounted the kinematic engine assembly (2) and gearbox (10) of the vehicle (1) , which, through the transmission (11), is linked to the differential (12) of the rear axle (4).
    Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any person skilled in the art understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought provided that it does not alter, change or modify its fundamental principle .
