DESCRIPTIVE MEMORY

TITLE AND TECHNICAL FIELD OF THE INVENTION

The present invention relates to the transportation and electromobility industry. In particular, the present invention is related to a multifunction modular tricycle, which presents a functional design that offers the possibility of being used in any place or situation, since its final configuration can be modified as it is composed of interneoated modules that They allow you to change your position with respect to the general structure, allowing different ways of using it and comfortable and safe driving, due to its traction system and independent suspension with stabilizer bar. It falls mainly within the technical sector for the manufacture of transport equipment in its broadest sense, although it can also be included in the sector of commerce and personal articles for domestic use related to the means of transport that facilitate the mobilization of people and things. in a more convenient and faster way.

STATE OF THE ART AND BACKGROUND OF THE INVENTION

Currently, there are numerous types of three-wheeled vehicles, and most of them have a front steerable wheel and two parallel rear drive wheels.

This class of vehicle allows the combination of the stability of a car with the maneuverability of a motorcycle by having a single front wheel. In fact, the front of the vehicle is generally capable of rolling motion, along with or relative to the rear, so that the vehicle can be propelled exactly like a two-wheel drive vehicle (providing the possibility for the driver to lean his body), while still maintaining, to a large extent, the intrinsic stability of a four-wheeled vehicle.

A bicycle is understood as a two-wheeled vehicle of the same size, or not, whose pedals transmit movement to the rear wheel by means of two sprockets and a chain, while the tricycle is conceived either as a three-wheeled vehicle or as a toy. three-wheeled child that moves through the action of pedals.

Although Herlihy (2004) specifies that artifacts were made in ancient Egypt rudimentary composed of two wheels joined by a bar, as in ancient China, although in this case the wheels were made of bamboo, it was Baron Christian Ludwig Drais von Sauerbronn in 1817, who designed the precursor machine of the current bicycle and motorcycle.

Within the state of the art is the publication US2017050696 that discloses a folding tricycle with a motorized axle that is driven by an electric motor and/or by pedals, a braking system, batteries for the electric motor, an electronic control device an electric motor, a steering assembly made up of a wheel and its axis, a handlebar, the tube that links the fork to the handlebar, a chassis made up of two segments aligned longitudinally and linked by a hinge, a seat with a distance regulator, where the tricycle can be used only in electric format or with pedals with electrical assistance, but does not disclose a comfortable and safe driving tricycle for having traction and independent suspension with stabilizer bar.

Another document is the application BG003889 U1 that discloses a tricycle that has two wheels of the same size and a third wheel of a different size, with the two equal wheels being linked to their axis an electric motor, a brake system, a pinion with its toothed plates and a speed device, presenting batteries for the electric motor, a braking device, an electronic device for controlling electric motors, a steering assembly made up of a wheel of different size and its axis, a handlebar, the tube that links the fork to the handlebar and a cylinder that contains it, presents a chassis made up of two segments aligned longitudinally and linked by a hinge, a seat with a distance regulator, where the tricycle can be used only in electric format or with pedals with electrical assistance, but it does not disclose a comfortable and safe driving tricycle for having traction and independent suspension with stabilizer bar.

Currently, and since 1839, when the first pedal bicycle was manufactured, there are various types of bicycles (domestic, mountain, racing, touring, folding, hybrid, tandem, BMX , and the tricycle or delivery bicycle), each one of which is oriented towards a different specific function, and although they all work on the basis of a sprocket chain, a system that presents a habitual release of the chain, they can also have an attached motor with its electric battery to replace the traction through the effort of the person, but none of them disclose a comfortable and safe driving tricycle for having independent suspension with stabilizer bar.

State of the art vehicles allow the user to maneuver easily and comfortably in urban traffic thanks to their limited width and great maneuverability with the advantage that the driver does not need to put his feet on the ground when stopping the vehicle. This type of vehicle provides greater security and protection in the presence of bad weather since, precisely because of its more stable structure, it can be more easily covered, for example to form a vehicle with a body that provides protection.

On the contrary, these vehicles suffer from certain problems and drawbacks, such as: inaccurate driving, in the sense of determining the vehicle's trajectory, due to the presence of a single wheel to steer the vehicle, with possible sliding maneuvers and problematic situations when braking/accelerating. The need to adopt a differential system for the drive wheels and the limitation involved in adopting drive systems on the drive wheels taking advantage of the small space available and the consequent difficulty of also inserting a passenger seat and/or a luggage rack and/or baggage only.

Today, most vehicles feature a single rigid design that does not allow for changes to their set-up, geometry, driving position, and drive system.

PROBLEMS TO BE SOLVED BY THE PRESENT INVENTION

The main objective of the present invention is to solve the previously mentioned problems and drawbacks, while providing a simple and lightweight three-wheeled vehicle, with comfortable and safe driving as it has traction and independent suspension with stabilizer bar.

This technology presents various advantages due to its possibility of having multiple final configurations, thus facilitating access to more types of users, and adapting to their needs using electrical energy from one or more batteries to mobilize, which generates a positive impact on environment.

The present invention is aimed at providing a three-wheeled vehicle that allows the inclination that favors its driving like that of a motor vehicle without having to include complex extra structures, which can be covered, for example, with a vehicle body, make available an inexpensive three-wheeler with room for a passenger and luggage, that is safe and that provides a certain comfort, provide a three-wheeled vehicle that does not have any differential but that nevertheless presents a solution that replaces it in a simple way, with the consequent saving in space occupation and the availability of more space for possible additional elements, providing the possibility of traction by pedals and chains, or by an electric motor connected to a battery with traction control. This makes it possible to solve the problem that when the battery runs out, it is possible to continue advancing through the use of pedals and chains (human traction).

All of the aforementioned is achieved in the present invention by means of a three-wheeled vehicle: with one steering wheel and two traction wheels that adapt to the terrain and to the inclinations in the curves with independent suspension and stabilizer bar to keep the vehicle as parallel to the road as possible. floor at all times, even in a curve, and the existence of electric motors connected to batteries and pedals that can be easily connected to the drive pinion of the two drive wheels, offering the possibility of adding or removing some of its parts. according to the user's need.

All this aims to achieve mobility with personal or commercial claims without polluting the environment.

For these reasons, this tricycle provides advantages that facilitate its use by ordinary people or people with reduced mobility, or who do not know, cannot or do not want to mount two wheels on bicycles or mopeds, since they cannot be kept stable. by themselves.

DETAILED DESCRIPTION OF THE INVENTION

This tricycle is a vehicle adaptable to different preferred configurations, since it allows the relocation, extraction or addition of some of its components, for different forms of application, or coupling a bicycle to its rear, which includes:

- A chassis or elongated body made up of two parts linked by a hinge and a damper.

The steering set.

Two traction sets.

The main axis at whose ends each of the traction assemblies will be fixed and pivoted.

A piece of greater length than width and of a certain thickness or height (which will vary its shape and height according to the design applied to it) that we will call a support base.

Batteries needed for electric motors.

A motor controller device that will have a built-in GPS global positioning system.

A button linked to each motor for manual control of the speed of the wheels.

The damper close to the steering wheel (can be one or more dampers) and the dampers linked to each drive assembly (may be one or more dampers).

One or more seats oriented towards the steering assembly or towards the traction assemblies.

A baul.

Means for fixing a bicycle fork to insert and fix the fork of a bicycle to the rear in order to be able to carry one more passenger or provide the towing function to someone who has had a flat tire on their bicycle.

For a better understanding, the mentioned elements are described below:

A chassis or elongated body: made up of two elongated parts aligned longitudinally and joined by a hinge and at least one shock absorber. Said chassis is responsible for supporting the rest of the elements that make up the tricycle, being able to present a lighting device at the ends, and in the preferred mode with the steering wheel forward, a support shaft will be inserted at the rear end to fix the fork of a common bicycle, once the front wheel has been removed. Said chassis has on its upper face a series of holes in line in the area opposite to the location of the trunk, related and communicated each one with a lateral hole in which a stem linked to a quick fixing device is inserted, thus allowing the installation of or remove orient the location of the chair towards the steering assembly or towards the traction assemblies depending on the chosen driving mode.

The steering assembly: made up of a wheel, the lateral footrests arranged on both sides of the front wheel axis, the fork with its corresponding anchors, in whose lower ends the wheel axis is inserted and fixed, the handlebar and the tubular axis of the steering assembly at the lower end of which the fork is fixed and the handlebar is fixed at the upper end, said tubular axis being inside a cylinder, which is fixed to the chassis, which allows it to rotate.

The main axis: the support base can present one or more horizontal through holes in the middle part of its sides, being that the main axis will be inserted in one of them, at whose ends each of the traction assemblies will be fixed and pivoted.

The support base: it is a piece of greater length than width and of a certain thickness, which will vary its shape and thickness, or height, according to the design configurations applied to it, in which the seat, trunk, etc. will be fixed. one or more shock absorbers, and the main fixing axis for the traction assemblies. It has on its upper face a series of vertical perforations in a line, those in the area closest to the steering assembly are for the seat and those in the opposite area are for inserting the trunk, which allow inserting the projections that the seat has in its lower face, locating it in one orientation or another depending on the configuration chosen with the steering assembly in front or behind, depending on which holes the seat is inserted into, it will be closer or further from the handlebars, thus allowing the desired distance to be adjusted with respect to of said handlebar. They also allow the projections that the trunk has in its lower part to be inserted.

In turn, the support base can be fixed to the chassis in different positions by inserting the protuberances or vertical rods that it has on its lower face into the vertical holes that the chassis has on a portion of its upper face. This also allows locating or relocating the support base at a certain distance from the handlebar by selecting the corresponding holes, allowing you to shorten or lengthen the trike.

In its middle lateral part, the support base has a series of through holes (1 to n) arranged horizontally in a linear or curvilinear fashion, in one of which it is inserted, traversing it from side to side, in the main axis, protruding its ends, to which the traction assemblies will be fixed, on which they will pivot, being limited in their movement by the shock absorbers. Being that said shock absorbers will be fixed at one end to a transversal axis fixed to the support base and at the other to a transversal axis fixed to the frame of the corresponding traction assembly. Being that the transversal axis fixed to the support base will be located in the corresponding opening that will contain the holes in which its ends can be fixed. For this purpose, in said opening there are horizontal holes arranged either linearly or curvilinearly, in a position directly related to the position of the existing holes to position the main axis. For example, in the case of having a shock absorber, a support base has 3 holes to locate the main axis, arranged vertically in a linear fashion, with a distance of 6 cm between the first, starting from the bottom, and the second, and a distance of 7 cm between the second and the third, then the holes to locate the transversal axis on which the shock will pivot will be located vertically, in a linear fashion, with a distance of 6 cm between the first, starting from the bottom, and the second, and a distance of 7 cm between the second and the third. In this way, the main axis can be located at different heights from the ground or by shortening the distance between the axes of the steering wheel and the traction wheels, in one way or another the center of gravity of the tricycle is modified, maintaining the shock absorber. in the same position relative to the ground so that it works properly.

Two independent traction assemblies: each one made up of a triangular frame or support, which is linked at the lower vertex to a wheel on whose axis there is an electric motor, a braking system, such as the brake disc, the brakes and the speed system with its pinion; in the upper vertex with one or several toothed chainrings and its speed system, to change the torque ratios depending on the conditions of use, whether it is other effort such as going uphill or more speed on the straight or downhill, the connecting rod and the pedal . The frame has a triangular shape, with the axis of the wheel fixed at the lower end or vertex. At the intermediate end or vertex, which remains in an intermediate position with respect to its height, the end of an axis is inserted that links it to the support base in such a way that it allows said frame to pivot, in a vertical plane with respect to said axis. . Above the imaginary line that would join this intermediate end with the upper end or vertex of the frame, the at least one shock absorber will be located, one end of it being linked to the frame by an axis that crosses its end, on which it pivots, and the other linked to the support base by an axis that crosses its end, on which it pivots, thus achieving the proper action of the shock absorber with respect to the correct distribution of the forces and at the same time allow placing the main axis on which the frame pivots in the desired position to define the height at which the chassis will be with respect to the ground, placing said main axis in the selected through hole located on the sides of the support base, where a stabilizer bar operatively joins the independent traction assemblies, to keep the tricycle horizontal even in a curve.

The energy to drive the electric motors comes from batteries, which are preferably lithium.

A GPS, to improve the location of the tricycle and the handling within the cities.

The shock absorbers: which are linked to the steering assembly and the traction assemblies, forming the independent damping assemblies per wheel close to the steering wheel and linked to the traction assemblies:

Steering wheel damping: the chassis is made up of two parts, or segments, that act longitudinally aligned and are linked by a lower hinge system that allows reducing the longitudinal space that the tricycle occupies when it is parked or stored vertically. On one of the facing faces thereof, in the area corresponding to the hinge, the end of a shock absorber is fixed to a transversal axis on which it pivots, while the other end of the shock absorber is fixed to the other side of the chassis. by means of a transversal axis on which it pivots, presenting said ends of the shock absorber inserted in part in facing slots or holes in the chassis. This system is in charge of absorbing the unevenness of the ground surface that affects the steering wheel.

Damping of the traction sets: each damper related to each traction set with at least one damper for each traction set, which is located on an imaginary line, which joins the intermediate end or vertex with the upper end or vertex of the frame . The shock absorber will be located aligned to said imaginary line, with one end of it attached to the frame by means of a transversal axis, on which it pivots; and the other end fixed to the support base by means of a transversal axis, on which it pivots, likewise the system is equipped with a torsion bar, either, this provision being of fundamental importance for the correct activation of the shock absorber to achieve an adequate distribution of the acting forces allowing the main axis, on which the frame pivots, to be fixed in the desired position, inserting said main axis into one of the holes -it could be one or more- on the sides of the support base to define the height at which the chassis will be in relation to the ground.

The seat: which is inserted and fixed in an operable way through holes or other means of adjustment or rotation, allowing it to be used with the steering assembly forward or rear, and a sliding and/or linear fixation with respect to the chassis.

The trunk: it is fixed in holes that the support base has in the rear part of its upper face in another preferred configuration with the steering assembly arranged forward.

Rear connection shaft for a bicycle: in another preferred configuration, the steering assembly arranged forward, the chassis at its rear end presents a through hole from side to side in which a shaft is inserted at whose ends it is possible to insert and fix the bicycle fork anchors. To do this, the front wheel of the bicycle to be connected to the tricycle will be removed and said axis will be inserted and fixed in the place where the removed wheel was. It will also be possible to connect a tricycle like the one in the present application instead of a bicycle. This will allow adding a companion on the bicycle or serve as a trailer in the event that a bicycle tire has been punctured.

All of the above allows the tricycle to be assembled in the following ways, to obtain different preferred configurations:

Use with trunk and electric motors,

Use without trunk and electric motors,

Use without trunk, electric motors and a bicycle, or tricycle, attached,

Use without trunk and without electric motors and with pedals, with the drive units in front,

Use without trunk, with electric motors and with pedals, with the drive units in front,

During its use, the tricycle will have the ability to adapt to the terrain, both with respect to the irregularities that it presents and before the action of turning, thanks to the existence of a stabilizer bar and traction assemblies that work as follows:

In the event of an irregularity in the terrain, said set will rise or fall, according to the type of irregularity found, keeping the wheels always in contact with the ground, thanks to the fact that each traction set can pivot on the main axis in which it is inserted. and to the action of the shock absorber that will counteract this movement trying to bring it back to its initial position, thus managing to cushion the effect on the rest of the structure,

Before the action of bending, the weight will move more towards the side on which it is bent, causing the traction set on that side to go up, causing the other traction set to go down, having to support less weight, and that side to rise a little. of the base support-chassis assembly, leaning towards the side that bends thanks to the action of the main axle that acts as a stabilizer bar, or you can also use a stabilizer bar apart from the main axle, thus keeping the wheels in contact with the ground and therefore maintaining traction, which is independent on each wheel, for which the motor controller device will operate them according to the rotation speed required by the bending action, for which a system is not necessary. differential action mechanic. In other words, the traction assemblies will adapt to this action, favoring the grip of the tricycle and its stability since the center of gravity is modified and the electronic control device will be in charge of making the outer wheel turn faster and at a lower rate. speed the inner wheel to the curve, thus supplanting the mechanical differential, or, if you prefer, you can not activate or put an electronic control for the rotation of the wheels in the curves and simply place a manual button connected to the motor of each wheel to control the speed of each one manually.
