    DESCRIPTION
    VEHICLE CARRIER SYSTEM AND VEHICLE LOADING METHOD IN A SYSTEM
    VEHICLE HOLDER
    Field of the Invention
    The present invention discloses a vehicle transport system.
    Specifically, the present invention relates to a vehicle transport system of the type that has a platform attached in at least one axis of rotation to a towing vehicle, for example, a crane or a railroad, said platform being intended to house a vehicle for his transport.
    Background of the invention
    At present there are many platforms adapted for transporting vehicles both by rail and road vehicles. These platforms are specially designed to be able to transport the load in two or more levels of height being adaptable to be able to load both vehicles and merchandise in the same cargo space and which allow different movements.
    The transport of cars is generally carried out on platforms where the only modularity they present is to be able to perform a manual adjustment of the position of the supports by means of manual mechanisms, where the tires of the different vehicles will fit to carry out the load, depending on the space they occupy or the volume of the cargo to be transported.
    However, at present, the movement of the platform once loaded requires a great effort and, consequently, reinforced materials that can withstand the effort required for the movement of the platform.
    Description of the invention
    In order to solve the problems of prior art systems, the present invention relates to a system for transporting vehicles that has a platform balancing mechanism that is held by a rotation axis, intended to accommodate A vehicle for transportation.
    The present invention has a mechanism for balancing the center of gravity of the vehicle once loaded, which gives the system a more efficient mode of operation of the turning motor, since, having the position of the center of

    35
    masses on the axis of rotation of the platform, the effort made by the engine is less than in the case of prior art systems, being able, consequently, with lower power engines that take up little space and reduce the cost of the engine , make turns to heavy vehicles, in addition to giving the platform a more stable operation in the dynamic behavior and being able to carry out a much safer cargo transport, that is, reducing the rebounds suffered by the platforms due to causes inherent in transport, eliminating the damages that the vehicles can suffer, as well as, in the road transport and facilitating the driving of the truck because the unwanted load movements that can unbalance the truck are eliminated.
    The present invention therefore solves the problem of transport platforms that in the case where the vehicle that is placed on the platform has its center of gravity very off-center with respect to the axis of rotation of the platform, it will suffer a great effort when making the rotation movement, even being unable to perform that movement. With the system of the present invention, any vehicle model can be loaded regardless of its mass, since, being able to align the axis of rotation with the center of mass, the required effort of the system to perform the turn is substantially less.
    The platform integrated with the mechanism of the invention can be part of a truck or consist of an independent platform or trailer, container or mobile or towable mobile box towable by a truck or tractor unit.
    Specifically, the platform has a front structure intended to come into contact with one of the axles of the vehicle to be loaded, for example, the front axle. On the other hand, the platform has a rear structure intended to come into contact with the axis opposite the axis that comes into contact with the front structure, for example, the rearmost axis of the vehicle. Additionally, the platform of the present invention has, on the one hand, means of relative displacement between the front structure and the rear structure in order to fit the vehicle to be loaded and, on the other hand, means of displacement of the vehicle, once fixed to the front and / or rear structure with respect to the platform.
    These means of movement of the vehicle allow to stabilize the load but, in order to determine if the load needs stabilization, it is necessary to have means for measuring the distribution of the load. The present invention contemplates various means of measuring said load distribution and in view of said measurements modifying the position of the vehicle with respect to the platform in order to obtain a neutral measurement which allows optimizing the force exerted on the platform to exert a rotation. and, in addition, avoid overstressing parts of the platform.

    In an exemplary embodiment, the platform comprises at least two longitudinal beams located at the same height and in parallel planes, which form the outer frame of said platform, these beams form what is called the front structure of the platform, which have two other beams positioned inside the first ones in a telescopic way, which move inside the first ones moved by an actuator, these form what is called the rear area of the platform.
    The rear structure of the platform has, for example, between the two longitudinal beams two horizontal supports, joined in solidarity with the longitudinal beams and in a fixed manner, located so that there is a gap between them to accommodate the wheels of one of the axles of the vehicle, it can be either the rear end if the vehicle is introduced so that the front part is first placed on the platform, or the front part, in the event that the vehicle enters so that the rear part is first placed in the platform.
    The front area can be arranged between the longitudinal beams that form the frame, in a preferred form of manufacture, at least one fixed support and two movable supports that can be moved along guides intended for it, between which the wheels of the other axle of the vehicle.
    According to another possible embodiment, the front structure can be arranged between the longitudinal beams that form the frame, at least two supports joined in solidarity with the beam and placed perpendicularly thereto. Among these supports are two rolling platforms, where the vehicles will place the other of its axles and on which it will have a route to travel.
    For the measurement of the load distribution, in the case where a hydraulic motor is used, the platform may have pressure measurement sensors integrated in the rotation motor, jointly and severally connected to the axis of rotation of the transport platform. These sensors measure the variations of pressures that occur in the actuator when a vehicle is placed on the transport platform, being able to calculate based on these measures the difference in weight between the front and rear axle and the new position it will have to adopt the vehicle so that the platform-vehicle assembly locates its center of gravity aligned perpendicular to the axis of rotation.
    To balance the center of gravity of the vehicle with respect to the axis of rotation of the platform, the vehicle is placed on the transport platform when it is located at ground level of the means of transport. Once the vehicle is placed, as described above, with one of its axles between the mobile supports of the front part of the platform, in a preferred embodiment, and with the other of its axles between the fixed supports of the rear part, the platform is raised slightly so that the sensor can measure the difference in weights between the front and rear axle. This sensor

    it sends the data to means of processing said data in order to send a signal to an actuator so that, if necessary, it moves the rear part of the platform inside the longitudinal beams of the front part, of this In this way, the actuator moves the rear part of the platform, which in turn leads to the fact that the vehicle is a rigid element, which moves the movable supports of the front part, thus achieving that everything moves the vehicle with respect to the axis of rotation that remains fixed.
    Once the sensor does not detect variation of pressures in the rotation motor, it will mean that the center of gravity of the vehicle in question and, consequently, said measurement is substantially neutral, therefore the load is aligned with the axis of rotation. Once this neutral measurement is achieved, the processing means will block the actuator, fixing the position of the platform in a completely balanced way, at this point the platform can be turned the necessary inclination by making a minimum effort by the turning motor. Thus guaranteeing a safer transport of cargo.

    Detailed description of one embodiment
    Figures 1 and 2 show a preferred embodiment of a system according to the present invention. In this example, the platform (1), has two parallel longitudinal beams (2, 3) and located at the same height that define the perimeter of the platform and have
    5

    inside an actuator (not shown) and a telescopic extension mechanism. Said actuator responsible for modifying the length of the beams (2, 3) through the telescopic extension mechanism. In this exemplary embodiment, each of the beams (2, 3) has at least one extension body (4, 5)
    On the other hand, the platform has a front part that is formed by a fixed support (7) located in the outermost area, perpendicular to the side beam and joined in solidarity therewith. In addition, it has a front structure (8) said front mobile structure being in relation to the beams (2, 3) by means of a guide system explained in greater detail with reference to Figures 3 and 4.
    In addition, the platform (1) has a rear structure that is attached to the front structure by the beams (2, 3) and, in particular, by the extension bodies (4, 5) arranged in the beams (2, 3). In short, the platform (1) has, in this way, means for the modification of the relative distance between the front structure (8) and the rear structure (19), by means of telescopic extension means.
    On the other hand, the platform (1) comprises a rotation motor (12) that is connected with rotation capacity by means of connection (121) to a support structure (201) defining the axis of rotation (120) of the platform , the intersection of said axis of rotation with the beams (2, 3) being the points of attachment of the platform to the vehicle transport system. These points are a very small area of support, hence the importance of being able to balance the load to be transported so as not to exert stress on these critical points.
    Figures 3 and 4 show in detail the front structure (9) which has a front support (9), a rear support (10) and a pair of guides (11) on its sides to allow movement on the beams (2 , 3), additionally, it presents a series of holes (110) to allow, by means of a pneumatic embossing system installed in the beams (2, 3), to secure the front structure (8) in a certain position. While this embulonado is not activated, this structure has the ability to move along the path of the guide (11). Thus, the front structure (9) has two types of movement, a first relative movement (L1) with respect to the rear structure (19) by means of telescopic extension means, and a second movement (L2) with respect to the beams (2, 3) but moving together with the rear structure, and, consequently, with respect to the axis of rotation (120) of the platform being both longitudinal movements (L1, L2) along the platform.
    According to a second embodiment of the platform (1), the front area thereof, is formed by at least two fixed supports (9 and 10), located perpendicular to the longitudinal beams (2 and 3) and joined in solidarity to them. Between the fixed supports there are two profiles joined in solidarity with the fixed supports (9 and 10) and placed parallel to the
    5
    10

    35
    beams (2 and 3). These supports provide robustness to the platform avoiding deformations when supporting load. Covering the gap between the fixed supports (9 and 10) and the profiles, flat structures (17 and 18) are placed on the base of the platform, to allow the vehicle to roll along this surface. Allowing in this way the displacement of the vehicle to later proceed to balance its axis of gravity with the axis of rotation of the platform.
    Through the vehicle transport system of the present invention, balancing of the vehicles to be transported by aligning the center of gravity thereof with respect to the axis of rotation of the platform is available. This is done through a first measurement stage, at the time of loading the vehicles, at this stage the platform is presented with the longitudinal beams (2 and 3) supported on the basis of the medium to be used to perform the transport. The vehicle is placed supporting one of its axes (through the tires) on the front structure, when performing this maneuver, the front structure is fixed by means of the pneumatic bagging, to avoid in this the movement of the vehicle along the beams
    Once one of the axes is adjacent to the front mobile support, the rear structure of the platform is adjusted, using the telescopic mechanism arranged between the beams (2, 3) below the vehicle by activating an actuator (6) , until the second axle tires are positioned adjacent to the rear structure (19). Finally, the car makes the final movement to get on the platform once it has adjusted to its wheelbase.
    When at least two axles of the vehicle are on the rear and front structures, the platform is raised slightly to allow a sensor integrated in the rotation motor (12), to measure the load distribution.
    The load distribution can be determined, for example, by load cells arranged on both sides of the axis of rotation. The difference in weight between the sides of the axis of rotation is indicative that the load is not balanced. Alternatively, the rotation motor can be used to perform these measurements, the measurement principle would be to determine the energy required by the motor to maintain the platform in a position substantially parallel to a reference surface. Said energy can be measured in terms of electric current or power in the case of electric motors or of pressures depending on hydraulic motors.
    The measurements of the load distribution are subsequently sent to data processing means such as an automaton, which releases the embulonado of the front structure and acts on the actuator (6), which telescopically displaces the rear part of the platform , and will increase or shorten the actuator stroke (6) as it is found

    located the vehicle in question. When the hydraulic cylinder moves the rear area of the platform, the front structure (8) moves in solidarity, moving the vehicle longitudinally on the platform. Once the measurements indicate that the load is balanced, that is, that the center of mass of the vehicle is aligned with the axis of rotation of the platform, at this point the automaton sets the position of the actuator, positioning the rear area of the platform and the pneumatic bagging is triggered, thus being fixed, balanced and completely secured the position of the vehicle on the platform.
    In another particular embodiment of the platform balancing, the front axle will be placed on the raceways (17 and 18) of the front area of the platform, then the actuator that telescopically displaces the rear area of the platform is activated until it fits the tires between the supports intended for this. Then, the platform is slightly raised so that the sensor can take pressure measurements to be able to perform the balancing as discussed in the preferred embodiment.
    Thus, when carrying out the tilt maneuver of the vehicle to adjust it to its transport position, the turning motor makes a minimum effort. Giving consistency, strength, durability and security to the system.
    Figure 5 shows another embodiment of a platform applicable to a system according to the present invention. In this case, as in the previous embodiments, the adjustment of the platform to the size of the vehicle is carried out by means of telescopic bodies (5), however, the balancing of the platform is carried out by movement of the vehicle once the platform is It has been locked at a certain distance by embedding the telescopic bodies.
    In this case, the movement of the vehicle on the platform is carried out by means of an actuator (60) that moves a platform with respect to the axis of rotation 120. This movement of the platform with respect to the axis of rotation (120) is achieved by joining the actuator (50) to an interconnecting beam (50) of the front structure (7) with the rear structure (19) so as to allow it to slide on a fixed profile (51) intended to be attached to the support structure. In this way the axis of rotation (120) is fixed with respect to the support structure and the platform is mobile with respect to said axis of rotation (120).
    In this embodiment, the rotation motor (12) would be attached to the profile (51) and the platform would move inside said profile (51).
    Referring now to Figure 6, the application of the platform explained in reference to Figures 1-4 to a car carrier system is shown. A vehicle (200) for transporting a series of cars (202) is shown in Figure 4.

    As explained above, the platform has means to define the effective distance of the platform (Dplat), that is, between the front structure (8) and the rear structure (19).
    On the other hand, the platform has means for the movement of the vehicle with respect to the axis of rotation (120), that is, to modify the distance between one of the axles of the vehicle and the axis of rotation (Dveh). As explained above, this displacement of the vehicle with respect to the axis of rotation can be carried out using the actuator used to modify the effective distance (Dplat) since, once said distance has been set, the extension or retraction of the actuator can used to move the entire platform with respect to the axis of rotation (120). In short, the objective is to match the axis of rotation (120) with the center of gravity of the vehicle.
    Although the present invention has been described in reference to particular examples in which the means for executing the first relative movement (L1) between the front and rear structures and the second movement (L2) between one of the structures and the beams (2, 3), it is possible to have independent mechanisms to execute these movements. For example, having a first actuator that modifies the length of the platform and a second actuator that displaces the load (that is, the vehicle) with respect to the axis of rotation of the platform (1).
    Specifically, the present invention discloses a vehicle transport system of the type comprising a platform adapted to receive a vehicle, said platform being connected to a support structure by means of a rotation-capable joint defining a rotation axis comprising said platform:
    • a front structure to receive one end of the vehicle
    • a rear structure to receive the other end of the vehicle;
    • relative displacement means between the front area and the rear area of the platform to adjust the distance between the zones to the size of the vehicle;
    said system comprising balancing means of the platform comprising an actuator for the movement of the vehicle with respect to the axis of rotation.
    The platform balancing means may preferably comprise means for measuring the distribution of the load with respect to the axis of rotation of the platform and, optionally, at least one force sensor such as, for example, a load cell, a pressure sensor or at least one motor and a sensor of the output power of said motor. In the case of hydraulic motors, the motor output power sensor can be a pressure sensor or, in the case of electric motors, the motor output power sensor can be an electrical power sensor and / or a sensor of electrical intensity

    Additionally, the balancing system may comprise processing means connected to the load distribution measuring means for, for example, emitting a signal to the actuator for vehicle displacement until a substantially neutral measurement is achieved, that is, the coincidence between the center of gravity of the vehicle and the axis of rotation.
    In order to provide means for the movement of the vehicles with respect to the axis of rotation of the platform, it is contemplated that the beams have a guide on which the front structure and the rear structure are arranged allowing the movement of the vehicle with respect to the platform . Additionally, the front structure and the rear structure can be connected by at least one telescopic rod and thus define the distance between the platforms.
    On the other hand, the present invention contemplates that the movement of the vehicle with respect to the axis of rotation can be carried out by executing a movement of the platform with respect to the axis of rotation.
    On the other hand, the present invention discloses a method of loading a vehicle in a vehicle transport system, said vehicle transport system comprising a platform comprising:
