    Land vehicle
    Technical sector of the invention
    The land vehicle of the present invention is one that allows its displacement with a low or even zero emission of polluting gases.
    Background of the invention
    Land vehicles such as cars, buses, trucks etc. are known. provided with wheels with rubber or rubber tires that allow their braking over a short distance. However, these types of vehicles are autonomous and necessarily require a fuel tank or batteries for their displacement, which occupy a substantial part of their interior. Currently, most autonomous vehicles are vehicles equipped with internal combustion engines, whose emissions are polluting gases and particles that cause pollution.
    Also known are vehicles that are devoid of fuel storage or batteries to achieve greater capacity, such as trams. These types of vehicles are fed by an overhead catenary through a trolley to drive an electric motor, thus not causing emissions of polluting gases derived from combustion. However, the trams are provided with metal wheels and are moved, confined, by metal rails, so that this type of vehicle is not only required to make journeys on authorized lanes but also requires a greater braking distance than the vehicles provided of tires causing serious accidents. In addition, this type of vehicle has a very high cost.
    It is therefore an objective of the present invention to disclose a land vehicle that causes less or even zero emission of pollutant gases, can be used anywhere and has a much lower cost than known vehicles.
    Explanation of the invention
    The land vehicle of the present invention is one of those comprising a chassis mounted on wheels provided with tires, said wheels being connected to a directional means to control the trajectory of the vehicle and to a means of traction to drive the vehicle, the means being traction adapted to be driven by an engine

    electric, and the vehicle also having an upper trolley connected to the electric motor and adapted to connect to a catenary.
    In essence, the vehicle is characterized in that, since the electric motor is provided with a positive pole and a negative pole for its electrical supply, the upper trolley is connected to the positive pole of the electric motor, and because the vehicle is provided in addition to a trolley bottom connected to the negative pole of the electric motor, the lower trolley being adapted to connect the negative pole of the electric motor to a rail arranged on the ground on which the vehicle circulates that only has the utility of evacuating the current, the electric motor being adapted to drive the traction means when it receives electric current between the upper trolley and the lower trolley, and the vehicle also being provided with auxiliary means adapted to drive the traction means when the electric motor does not receive electric current between the upper trolley and the bottom trolley Advantageously, the vehicle is also provided with auxiliary means adapted to drive the traction means when the electric motor does not receive electric current between the upper trolley and the lower trolley, so that the auxiliary means can be used to move the vehicle even when This is not connected between the catenary and the rail, that is, it can be used anywhere. Naturally, it is anticipated that the catenary is formed by one or more parallel filaments, just as the rail can be formed by a single bar nailed to the ground or to the asphalt as well as multiple parallel bars nailed to the ground, for a more efficient transport of the electric current.
    In a variant embodiment, the auxiliary means are an internal combustion or explosion combustion engine, provided with pistons, adapted to use a fuel such as gasoline, diesel, gas or other fuels. This internal combustion or explosion engine is connected to the traction means by way of auxiliary means to drive the traction means and move the vehicle when it is not connected between the catenary and the rail. It is envisaged that the driver can start the auxiliary engine when driving the vehicle out of the path provided with catenary and rail, thus allowing advantageously to use the electric motor when it is in a path provided with catenary and rail and use the auxiliary fuel engine when It is outside the route provided with catenary and rail.
    In another variant of realization, the auxiliary means can be electric batteries connected to the electric motor, which can be advantageously used to power the electric motor and thus drive the traction means and move the vehicle when the

    vehicle is out of the path provided with catenary and rail, or no current flows between them. In this way, the driver can advantageously establish that the electric motor is fed from the batteries when it is not fed from the current between the upper trolley and the lower trolley.
    Naturally, it is also provided that the vehicle is provided with both auxiliary means in the form of an internal combustion or explosion engine and auxiliary means in the form of batteries connected to the electric motor, allowing the driver to choose the auxiliary means to actuate when the electric motor is not fed through the upper trolley and the lower trolley, for example by means of different control switches.
    It is also known that, although the electric vehicle may be provided with a single electric motor, it is also provided that it comprises a plurality of electric motors connected to the upper trolley and the lower trolley, for example, one in each pair of driving wheels.
    According to another characteristic of the invention, the end of the upper trolley is provided with a transverse horizontal upper terminal that facilitates contact with the catenary arranged along the circuit for the vehicle travel in a longitudinal direction, whereby the upper terminal will be transversal to both the catenary and the direction of the vehicle.
    According to another characteristic of the invention, the end of the lower trolley is provided with a transverse horizontal lower terminal that facilitates contact with the rail arranged along the circuit for the vehicle travel in a longitudinal direction, whereby the lower terminal will be transversal to both the lane and the direction of the vehicle. It is therefore envisaged that the upper terminal and the lower terminal, both preferably horizontal, are parallel. The fact that the upper terminal and the lower terminal are horizontal advantageously allows the vehicle to move laterally to a certain extent while maintaining contact with the catenary and the rail.
    According to another characteristic of the invention, the lower terminal of the lower trolley is provided with auxiliary wheels at its ends that allow the lower terminal of the lower trolley to be positioned at a minimum and sufficient height to contact the rail without touching the ground.
    According to another aspect of the invention, the wheels are made of rubber improving the grip of the vehicle on the ground, which substantially improves its braking distance.

    According to another characteristic of the invention, the vehicle comprises warning means, such as a pilot light or an acoustic warning, connected between the upper trolley and the lower trolley to notify the driver when no electric current circulates between the upper trolley and the trolley lower, so the electric motor is not being powered by the catenary and rail assembly. In this case, the driver should operate the auxiliary means to continue driving the traction means and thus continue the vehicle's progress. It is envisaged that another variant of realization can be performed by means of electronic control components, so that the driver does not manually activate the auxiliary means.
    Brief description of the drawings
    To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:
    Fig. 1 shows a side view of a schematic embodiment of the land vehicle of the present invention
    Fig. 2 shows section AA of the land vehicle of Fig. 1;
    Fig. 3 presents an operating scheme of a variant of the land vehicle of the present invention when the auxiliary means is an internal combustion or explosion engine; Y
    Fig. 4 presents an operating scheme of a second variant of the land vehicle of the present invention when the auxiliary means is one or more electric batteries.
    Detailed description of the drawings
    Figs. 1 and 2 schematically present a land vehicle 1 of the present invention that can be both a bus, a car, a truck or any other type of vehicle that allows the movement on land on wheels and that comprises a chassis 2 mounted on wheels 3 provided with rubber or rubber tires that allow the vehicle to move and allow its braking in a short distance, since the wheels 3 provided with tires offer a good grip on the ground 20 on which the vehicle moves 1. As will be seen later, the wheels 3 are connected to means of direction 4 that allow controlling the trajectory of the vehicle, favoring the rotation of the wheels through a steering wheel in a known manner. Also the wheels 3 are connected to
    5
    10
    fifteen

    35
    traction means 5 that allow the wheels 3 to be turned to drive the vehicle. Naturally, it is anticipated that some wheels 3 are driving wheels and are connected to the traction means 5, while other wheels 3 are steering wheels and are connected to the steering means 4, similar to the wheels 3 of the vehicles 1 known land, such as cars, trucks or buses.
    The vehicle 1 can either move in a circuit provided with a set of catenary 10 and rail 12, feeding on the electric current between the catenary 10 and rail 12 or outside the circuit, whereby the traction means 5 will be operated by means of auxiliary means 13 adapted to drive the traction means 5 when the vehicle 1 cannot feed on the electric current between the catenary 10 and the rail 12, as will be detailed below.
    As can be seen in Figs. 1 and 2, the vehicle 1 is provided with an upper trolley 9 and a lower trolley 11 protruding from the chassis 2 of the vehicle 1. Thus, the upper trolley 9 is adapted to be connected to a catenary 10 that runs over the vehicle 1 in an adapted rail and the lower trolley 11 is adapted to be connected to a rail 12 disposed on the floor 20 of said adapted rail on which the vehicle 1 circulates.
    The lane in which said vehicle 1 can be circulated is provided with a catenary 10, which as can be seen in Figs. 1 and 2 can be formed by a filament, and a rail 12 that can be formed by a bar. Between the catenary 10 and the rail 12 it is expected that there is a voltage difference so that after connecting an electric current from the catenary 10 to the rail 12 is circulated. This voltage difference can be established by a generator 21 in the manner illustrated. Naturally, it is envisioned that the generator 21 may be of a different nature and even that it is part of an electrical network that serves to power the catenary assembly 10 and rail 12.
    As can be seen in Figs. 1 and 2, the end of the upper trolley 9 is provided with a horizontal upper terminal 17 allowing contact with the catenary 10 and the end of the lower trolley 11 is provided with a horizontal lower terminal 18 allowing contact with the rail 12, so that although the vehicle is not exactly centered on the rail, a good electrical contact is achieved and allows the driver to make small lateral displacements, for example to overcome an obstacle, without losing contact with the catenary 10 and the rail 12.

    For a better contact of the lower terminal 18 of the lower trolley 11 with the rail 12, it can be seen that the lower terminal 18 is provided with auxiliary wheels 19 at its ends that allow the lower terminal 18 of the lower trolley 11 to be properly disposed on the rail 10 without rubbing the floor 20. It is also provided that the lower terminal 18 of the lower trolley 11 is provided with a sensor, such as a contact sensor that determines the height at which the lower terminal 18 of the lower trolley should be placed. 11 to correctly contact rail 12. Naturally, it is anticipated that both the upper trolley 9 and the lower trolley 11 are retractable or can be raised and lowered at will, so that the driver of the vehicle
    I can drive them at will to contact, as the case may be, with catenary 10 and rail 12. It is also envisaged that vehicle 1 is provided with warning means, such as a light pilot or acoustic warning, connected between the trolley upper 9 and lower trolley 11, so that the driver can be informed of whether the upper trolley 9 and the lower trolley
    II make good contact and through them electric current flows to power the electric motor 6.
    As illustrated in Fig. 3, the traction means 5 of the vehicle 1 are adapted to be driven by an electric motor 6, so that when the electric motor 6 is powered, the traction means 5 that rotates the wheels 3 is driven Naturally, it is envisioned that the driving means 5 of the vehicle can be regulated by a driver of the vehicle 1, for example, by means of an accelerator pedal that allows the wheels to rotate more or less rapidly, in a known manner. As can be seen, the electric motor 6 is provided with a positive pole 7 and a negative pole 8 for its power supply, the positive pole 7 being adapted to be connected to a positive electrical terminal, that is to the positive part of a difference of potential and the negative pole 8 adapted to connect to a negative electrical terminal, that is to the negative part of a potential difference. Naturally, the designations positive pole 7 and negative pole 8 are expected to be interchangeable depending on the nature of the electric motor 6 or there is no distinction between the poles.
    As can be seen in Fig. 3, the upper trolley 9 is connected to the positive pole 7 of the electric motor 6, and the lower trolley 11 is connected to the negative pole 8 of the electric motor 6, the electric motor 6 being adapted to drive the traction means 5 when receiving electric current between the upper trolley 9 and the lower trolley 11. It is envisioned that one or more electric motors 6 can be installed in the vehicle as necessary, for example, it is possible that each pair of driving wheels is associated to an electric motor 6.
    Advantageously, the vehicle is also provided with auxiliary means 13 adapted

    to drive the traction means 5 when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11. These auxiliary means 13 in the variant shown in Fig. 3 are an internal combustion engine, for example, a piston engine that is fed by gasoline or diesel. Thus, when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11, the driver can start the internal combustion engine 14 that forms the auxiliary means 13 to maintain the drive of the traction means 5 and thus being able to continue moving the vehicle 1 when it is not in a lane provided with catenary 10 and rail 12. Naturally, the traction means 5 will be duly provided with known mechanisms to allow its operation both by the electric motor 6 and by the internal combustion engine 14 of the auxiliary means 13. As indicated above, the wheels 3 will also be connected to means of direction 4, in a known manner, to control the trajectory of the vehicle 1.
    Fig. 4 shows another variant embodiment of the vehicle in which the auxiliary means 13 adapted to drive the traction means 5 when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11 are one or more batteries electric 15. In this case, unlike the variant of embodiment described above in Fig. 3 it will not be necessary for the traction means 5 to be prepared to receive drive from two different motors, but it will only be necessary for them to be prepared to receive electric motor drive 6, as can be seen in Fig. 4, in this case the auxiliary means 13 will be one or more electric batteries 15 and the electric motor 6 will be prepared to be powered by said one or more electric batteries 15 when not receive electric current between the upper trolley 9 and the lower trolley 11. Naturally, it is envisioned that the electric batteries 15 can be recharged, for example ap from the energy recovered by the braking of vehicle 1, in a known manner.
    It is also envisioned that the auxiliary means 13 are an internal combustion engine assembly 14 and electric batteries 15, combining the schemes of Figs. 3 and 4 and allowing, for example, the driver to decide whether to activate the internal combustion engine 14 or the electric batteries 15 as it deems most convenient when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11.
