    TRAILER AND PLATFORM WITH SELF-PROPELLED ELECTRIC SHAFT FORHEAVY ROAD TRANSPORTATION
    The present invention relates to a trailer or platformof the type that is linked to a tractor unit for theheavy road transport and that has the peculiarity ofcomprise at least one self-propelled shaft by two motorselectrical, which allows, among other advantages, a better
    1 control of the convoy, lower fuel consumption and, consequently, a reduction in the pollutant emissions of the tractor unit itself. State of the art
    1 A trailer or semi-trailer is, by definition, a vehicle that lacks its own propulsion and is designed to withstand a certain load, and must be associated with a self-propelled tractor unit for mobility. This tractor unit is on which the necessary tensile force falls. Also on the tractor unit lies part of the inertia and load that the trailer supports.
    On the other hand, usually, the trailer is interchangeable, it isthat is, it has fastening means that allows its bondingphysics with different tractor units and conform based ona chassis with its corresponding axles for the wheels,generally a minimum of two and up to four and five axes, whichsupport a loading surface, be it of the platform type,van or container and that, depending on its weight and dimensions,incorporates own brakes related to the brakes of thetractor unit through an electronic central located inthe cabin.
    In any case, the different types of existing trailers
    in the market share an essential feature sincementioned, i.e. they lack their own propulsion, whichthey always have an added tare for the tractor unit thatIt adds to the weight of the load. The only innovation in that aspectthey are called << carrier axes >> of the axis of rotation typefree and working in tandem, incorporating a mechanismtire that allows its elevation to reduce its weight onthe wheels and their wear or their descent tobear the weight of the load according to the needs of the
    1 driving
    To avoid these inconveniences, the document is knownWO2016116655 describing a semi-trailer or platform forheavy and special transport that includes at least one axis
    1 self-propelled by electric motors. In addition, EP2394889 refers to a trailer equipped with an additional traction system that describes a dragged element that can be a trailer or semi-trailer, which comprises at least one of the axles, a pair of symmetrical and independent electric motors each one tied to one of the wheels. Similarly, documents US2005000739, US7338335, FR2854122 and WO2013076607 disclose trailers that include at least one self-propelled axle with a pair of independent electric motors connected to each of the wheels that propel it.
    However, the documents cited do not describe anysystem with motors arranged contiguously andindependent between them, embedded in the shaft, so it isa system that, facilitating the propulsion of thetrailer, any of the wheels can be used in a wayindependent as a driving wheel.
    Description of the invention
    It is an object of the invention a trailer and axle platform
    self-propelled electric for heavy road transportwhich, being connected to the electronic control unit of the unittractor unit, comprises a pair of electric motors in at leastan axle of the wheels of said trailer and platform. Theengines are associated one to each wheel and, convenientlydimensioned, they are embedded in the shaft, but not housed in theirtunneled interior. That is, the axis cannot be tunneled,because it loses mechanical resistance characteristics and,In addition, this solution complicates the connections of
    1 engines.
    Electric motors are independent of each other, bothphysically as in operation. Therefore, they can workone by one, separately (for example, with an electric motor
    1 on and the other off) working simultaneously. The use of two engines responds to the need to obtain more power without loading the axle with excessive weight. The rest of the axle structure conforms to a conventional configuration with the discs or plates located at its ends and linked to the studs for the coupling of the rim and the corresponding wheels. When the axis of force of the electric motors arranged connected to it rotates, the rotation is transmitted to the discs or plates and from these to the tires and wheels.
    The torque of electric motors are of the conventional type (forexample, those described in WO9840235) installed in at least onetrailer axle or platform and that are powered by, atless, a battery, preferably lithium or equivalent,arranged on the floor of the trailer or platform and which, in turn,recharges by means of cells, solar panels or cellsconveniently located on the top or deck of thetrailer. It is important to keep in mind that, not all axesof the trailer or platform incorporate a couple of engineselectrical, at least one free shaft must remain.
    As already indicated, electric motors act ontheir respective wheels individually, in such a waythat from the electronic central of the head or tractor unitit is possible to act on one or the other engine, or both at the same time (foreach of the drive axles that the trailer has) turning inthis last case in a coordinated way and logically to itspeed.
    1 The possibility of independent activation of each of the wheels on the driving axle of the trailer or platform gives the invention great versatility compared to the documents known in the state of the art, since on certain occasions the use of a single engine in the
    1 self-propelled axle, for example, when there is little load or it is necessary to compensate the inertia of the trailer in certain turns, in addition to preserving the life of the motors and batteries

Forexperts in the field, other objects, advantages andfeatures of the invention will be apparent in part from thedescription and in part of the practice of the invention. Thefollowing examples and drawings are provided by way ofillustration, and are not intended to restrict thisinvention. In addition, the present invention covers allpossible combinations of particular embodiments andpreferred here indicated. Brief description of the figures
    Next, a brief description of aseries of drawings that help to better understand the invention and
    that expressly relate to an embodiment of saidinvention presented as a non-limiting example of this.
    FIG. 1 shows a schematic view of a convoy thatincludes platform (100) in accordance with thisinvention.
    FIG. 2 shows a schematic detail view of an axis.self-propelled electric (1) in accordance with this
    1 invention
    FIG. 3 shows a second schematic view of a convoywhich includes the platform (100) in accordance with thisinvention. Statement of a detailed embodiment of the invention
    As can be seen in the attached figures, thedevice of the invention is a platform (100) or chassisintended to support the trailer itself. In thePresent specification, platform and trailer (100) areused together or separately interchangeably, beingReferring this characteristic to the same physical element.
    The platform (100) incorporates at least one drive shaft (1) ofpreferably tubular configuration, in which they fitwheels (101,101 ’) of the type conventionally used inthe heavy transport trailers and platforms (100) inhighway.
    In a preferred embodiment, at least one of the driving axles(1,1 ’) includes, embedded in this drive shaft (1), twoelectric motors (2,2 ’) that act individually on thewheels (101,101 ’), an electric motor for each wheel. Theelectric motors (2,2 ’) are connected to their respective
    wheels (101,101 ’) through two parts or parts of the axlemotor (10,10 ’) through the corresponding discs or platesand, where appropriate, of the cardan if it is non-collinear axes.
    Electric motors (2.2 ’) converts traditional axles
    (1) on self-propelled shafts that are connected with a
    electronic control unit (3) located in the unit or tractor unit(200). Thus, at least one axle (1) of a trailer and platform
    (100) conventional becomes self-propelled by including
    1 advantageously a pair of electric motors (2.2 ’) embedded in the shaft itself (1) and duly fixed thereto by anchoring means.
    These electric motors (2,2 ’) are arranged so
    1 contiguous, to save space on the drive shaft (1) and contribute to its stability by the distribution of loads on the same drive shaft (1). However, both electric motors (2.2 ') are embedded independently on the drive shaft (1), without mechanical relationship between them, so that each of said electric motors (2.2') can actuate individualized form to its respective wheel (101,101 ') to which it is associated, according to the guidelines programmed in the electronic control unit (3) of the tractor unit (200).
    The electric motors (2,2 ’) transmit their turning movement tothrough the drive shaft (1) to a plate or disc (5.5 ’) which, at itsonce, it is associated by studs (6.6 ’) to the setformed by tires and wheels (101,101 ’). In addition, theelectric motors (2,2 ’) are powered by at least onebattery (4), preferably lithium or similar and that remainsarranged on the floor of the platform (100). These batteries, toin turn, they are recharged by means of solar panels (7)placed on the trailer itself.
    Based on the above, it should be noted that the incorporation of
    electric motors (2,2 ’) to the axles of a trailer and platform
    (100) for heavy transport implies substantial advantages in thedriving. Indeed, the use of the invention achieves agreater control of the convoy, since it allows you to choose from eithermanually or previously programmed in the electronic exchange
    (3) of the tractor unit (200) different variables in thedriving it, such as the turning speed ofelectric motors (2.2 ’), their activation, the
    number of electric motors (2.2 ’) and the drive shaft (1) that is 1 active to support the weight and inertia of the load.
    Similarly, work with electric motors (2.2 ’) in theaxles (1) of the trailer and platform (100) imposes savingsSignificant fuel consumed by the tractor unit
    1 (200) and a decrease in pollutant emissions. Logically, the conformation of the driving axles (1) is variable based on the needs and characteristics of each vehicle, in the same way as with the conventional axles, in what varies its length or structure, model and characteristics of the tires and wheels (101,101 ').
    Particularly, the present invention increases the strength ofconvoy and wheel grip traction, with increasedsafety on steep slopes, both on climbs and ondrops and unexpected driving situations such asFor example, the reduction of the scissor effect in sudden braking ordisplacements of the supported load. The work of the enginesElectrical (2,2 ’) is equally positive as it does not requiretransmissions and gears while being self-ventilated, notneed any additional cooling system orexternal ventilation, which makes them suitable for beingembedded in the drive shaft (1).
