DISPOSITIVO DE FRENO REGENERATIVO NEUMATICOPNEUMATIC REGENERATIVE BRAKE DEVICE
OBJETO DE LA INVENCION:OBJECT OF THE INVENTION:
La presente invention afecta al sector de la automocion y mas concretamente al campo del ciclismo y se refiere a un dispositivo de frenado que es capaz de almacenar la energla cinetica absorbida durante el proceso de frenado de la bicicleta, mediante compresion de aire ambiente y su almacenado como aire comprimido, para despues ser devuelta esta energla como ayuda al pedaleo cuando el ciclista desea ayuda supletoria a su esfuerzo muscular, bien para vencer una mayor resistencia al avance o por un incremento de velocidad o ambos a la vez.The present invention affects the automotive sector and more specifically the field of cycling and refers to a braking device that is capable of storing the kinetic energy absorbed during the braking process of the bicycle, by compressing ambient air and storing it. As compressed air, after this energy is returned as an aid to pedaling when the cyclist wants extra help to his muscular effort, either to overcome a greater resistance to the advance or by an increase in speed or both at the same time.
Cuando el ciclista aprieta la maneta de frenado para disminuir su velocidad, un compresor radial de paletas es movido por la rueda de la bicicleta a traves de un multiplicador de engranajes comprimiendo el aire ambiente y conduciendolo a traves de una electrovalvula a un deposito de aire a presion que es solidario con el buje de la rueda de la bicicleta. Cuando el ciclista no precisa frenar, la rueda es movida exclusivamente con la energla muscular del ciclista. Por contra, cuando el ciclista necesita ayuda a su pedaleo, aprieta otra maneta, que podemos denominar aceleradora, que pilota la electrovalvula anterior en sentido opuesto, comunicando ahora el aire comprimido del deposito con la entrada del compresor de forma que este aire presurizado mueve al mismo compresor en el mismo sentido que antes, haciendo ahora las funciones de motor y mediante el sistema de engranajes planetario haciendo ahora de reductor y por tanto aumentando el par del giro sobre el buje de la rueda motriz.When the cyclist squeezes the brake lever to decrease its speed, a radial vane compressor is moved by the bicycle wheel through a gear multiplier compressing the ambient air and driving it through an electrovalve to an air reservoir to pressure that is integral with the hub of the bicycle wheel. When the cyclist does not need to brake, the wheel is moved exclusively with the muscular energy of the cyclist. On the other hand, when the cyclist needs help with his pedaling, he presses another lever, which we can call accelerator, which drives the previous solenoid valve in the opposite direction, now communicating the compressed air of the tank with the compressor inlet so that this pressurized air moves to the same compressor in the same direction as before, now doing the motor functions and using the planetary gear system now acting as a reducer and therefore increasing the torque on the hub of the driving wheel.
ANTECEDENTES DE LA INVENCION:BACKGROUND OF THE INVENTION:
Durante los ultimos tiempos, debido a una mayor concienciacion para no derrochar la energla, ya que supone un mayor consumo de combustibles fosiles y por ende una mayor contamination y degradation del planeta, se ha tratado de la regeneration de energla en todos los ambitos, incluido en el campo de la automocion. Se menciona como ejemplo en este campo de la automocion, el desarrollo y utilization del KERS (Kinetic Energy Regenerative System) en el deporte de automoviles de competition. Esta utilizacion de laDuring recent times, due to greater awareness to avoid wasting energy, since it implies a higher consumption of fossil fuels and therefore a greater contamination and degradation of the planet, it has been about the regeneration of energy in all areas, including in the automotive field. It is mentioned as an example in this field of automotive, the development and utilization of KERS (Kinetic Energy Regenerative System) in the sport of racing cars. This use of the

energla generada en la frenada esta siendo, con mayor razon, utilizada en vehlculos no autopropulsados cuyo movimiento es debido al esfuerzo muscular de las personas. Se esta investigando e innovando en nuevos sistemas de frenado regenerativo en bicicletas cuya energla desarrollada durante el frenado se utiliza para generar energla electrica que se almacena en baterlas para ser utilizada cuando el ciclista necesita una ayuda suplementaria a su pedaleo, mediante motores electricos, siendo conocidas este tipo de bicicletas como e-bikes. Hay mucha information y patentes en cuanto al estado actual, de tecnicas diferentes para este tipo de regeneration electrica en bicicletas, y que no se pormenorizan en este documento ya no afectan a la invention aqul presentada.The energy generated in braking is being, with greater reason, used in non-self-propelled vehicles whose movement is due to people's muscular effort. Research and innovation is being carried out in new regenerative braking systems in bicycles whose energy developed during braking is used to generate electric energy that is stored in batteries to be used when the cyclist needs supplementary assistance to his pedaling, using electric motors, being known This type of bicycle as e-bikes. There is a lot of information and patents regarding the current state, of different techniques for this type of electric regeneration in bicycles, and that are not detailed in this document no longer affect the invention presented here.
No obstante no se ha encontrado en el estado actual de la tecnica ningun dispositivo que convierta la energla desarrollada durante el frenado de la bicicleta en aire comprimido, para ser posteriormente utilizado en mover un motor neumatico que ayude al pedaleo del ciclista.However, no device that converts the energy developed during braking of the bicycle into compressed air has been found in the current state of the art, to be subsequently used in moving a pneumatic motor that helps the cyclist's pedaling.
Se presenta en esta invencion un dispositivo que utiliza esta idea de regeneracion de la energla desarrollada en la frenada, en la compresion del aire ambiental y su almacenamiento una vez comprimido en un deposito, para que al ser necesaria para superar una mayor resistencia al avance de la bicicleta o un incremento de la velocidad, o ambos a la vez, se expanda el aire comprimido almacenado, en el propio compresor para que ahora haga las funciones de motor neumatico, ayudando as! a incrementar el par producido por el pedaleo del ciclista.In this invention a device is presented that uses this idea of regeneration of the energy developed in braking, in the compression of the ambient air and its storage once compressed in a tank, so that being necessary to overcome a greater resistance to the advance of the bicycle or an increase in speed, or both at the same time, the stored compressed air is expanded, in the compressor itself so that it now functions as a pneumatic motor, thus helping! to increase the torque produced by the cyclist's pedaling.
Teniendo en cuenta que la bicicleta no es una maquina autopropulsada, sino que debe ser movida con esfuerzo muscular del ciclista, es de vital importancia el menor incremento posible en el peso de la maquina, por lo que todos los elementos constructivos deben ser realizados en materiales de poco peso especlfico, a ser posible sinteticos o aleaciones metalicas ligeras.Taking into account that the bicycle is not a self-propelled machine, but must be moved with muscular effort from the cyclist, the smallest possible increase in the weight of the machine is vital, so all construction elements must be made of materials of low specific weight, if possible synthetic or light metal alloys.
Algunas de las ventajas tecnicas que aporta esta invencion se mencionan a continuation:Some of the technical advantages provided by this invention are mentioned below:
Una ventaja tecnica importante anadida que presenta la invencion aqul redactada frente a la regeneracion de la frenada produciendo energla electrica, que se emplea en las e- bikes, es que la acumulacion de energla electrica necesita de baterlas siendo estas de alto peso especlfico, as! como lo es tambien el cobre utilizado en los bobinados de los motores electricos. En la invencion que aqul se presenta la acumulacion de aire comprimido puede realizarse en deposito realizado en material sintetico de bajo pesoAn important technical advantage added by the invention here written against the regeneration of braking producing electric energy, which is used in ebikes, is that the accumulation of electric energy needs to be batteries being these of high specific weight, so! as is the copper used in the windings of electric motors. In the invention presented here, the accumulation of compressed air can be carried out in a tank made of synthetic material of low weight.

DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION
La presente invencion queda establecida y caracterizada en las reivindicaciones independientes, mientras que las reivindicaciones dependientes describen otras caracterlsticas de la misma.The present invention is established and characterized in the independent claims, while the dependent claims describe other features thereof.
La presente invencion se refiere a un dispositivo de freno regenerativo neumatico para ayuda al pedaleo de los ciclistas. El dispositivo en cuestion se basa en un sistema recuperador de la energla mediante aire comprimido que se acumula durante el frenado de la bicicleta en un deposito sintetico (2) que circunda externamente al buje de la rueda motriz de la bicicleta. Cuando el ciclista aprieta la maneta de frenado, el circuito hidraulico de frenos frena progresivamente un disco de freno (6) que es solidario con el eje portasatelites (24) de un tren epicicloidal simple que esta ubicado en un lateral dentro del buje (23) de la rueda motriz. El eje del planeta (14) del tren de engranajes es solidario con el eje del rotor del compresor radial de paletas (20). Al frenar el citado disco (6) y por tanto al eje portasatelites (24), se produce una multiplication de la rotation del planeta (14) cuyo eje es solidario con el eje del compresor, con respecto a la rotacion de la rueda, que es solidaria con la corona (15) del tren planetario, pero en sentido inverso a la rotacion de la rueda motriz de la bicicleta. A la vez que se aprieta la maneta de frenado, el sistema electrico alimentado con una baterla ubicada en el recipiente cillndrico de la carcasa (7), pilota una electrovalvula (16) de cuatro vlas y tres posiciones, conectando la salida del aire comprimido del compresor, con el deposito (2) sintetico que rodea el exterior del buje (23). Cuando se precisa de una frenada muy energica, el ciclista aprieta al maximo la maneta de frenado presurizando mas el aceite del circuito de frenos y en este caso ademas de parar el disco (6) solidario al eje portasatelites (24), se activa una valvula limitadora de presion que deja paso de aceite hacia el bombln (10) que realiza un frenado convencional sobre el disco (5). En este caso se paraliza la rueda motriz y por tanto la corona (15) y el portasatelites (24) dejando de funcionar tambien el compresor de aire (20). La rueda motriz de la bicicleta quedarla bloqueada por ser solidaria con la corona (15) del tren planetario que ha sido detenida con el disco de freno (5).The present invention relates to a pneumatic regenerative brake device for cycling pedaling assistance. The device in question is based on an energy recovery system by means of compressed air that accumulates during the braking of the bicycle in a synthetic tank (2) that surrounds the hub of the driving wheel of the bicycle externally. When the cyclist squeezes the brake lever, the hydraulic brake circuit progressively brakes a brake disc (6) that is integral with the satellite axle (24) of a simple epicyclic train that is located on one side inside the hub (23) of the driving wheel. The planet axis (14) of the gear train is integral with the rotor shaft of the radial vane compressor (20). By braking the said disk (6) and therefore the satellite-carrier axis (24), a multiplication of the rotation of the planet (14) takes place, whose axis is integral with the axis of the compressor, with respect to the rotation of the wheel, which It is in solidarity with the crown (15) of the planetary train, but in the opposite direction to the rotation of the driving wheel of the bicycle. While the braking lever is pressed, the electric system powered by a battery located in the cylindrical container of the housing (7), pilots a four-way, three-position solenoid valve (16), connecting the compressed air outlet of the compressor, with the synthetic tank (2) surrounding the outside of the bushing (23). When a very energetic braking is required, the cyclist squeezes the braking lever to the maximum, pressurizing the brake circuit oil more and in this case, in addition to stopping the disc (6) integral with the satellite carrier axis (24), a valve is activated pressure limiter that allows oil to flow into the cylinder (10) that performs conventional braking on the disc (5). In this case the driving wheel is paralyzed and therefore the crown (15) and the satellite carrier (24) also stopping the air compressor (20). The driving wheel of the bicycle will be blocked by being integral with the crown (15) of the planetary train that has been stopped with the brake disc (5).

Cuando el ciclista precisa ayuda a su pedaleo para vencer una mayor resistencia al avance o para aumentar la velocidad de la bicicleta, activa otra maneta distinta o acelerador, que al igual que antes el circuito hidraulico frena el disco (6) que ralentiza el eje portasatelites (24) de forma que cuanto mayor sea este frenado mayor sera la multiplication de la rueda planeta (14) solidaria con el eje del compresor, alcanzandose cuando se paraliza dicho eje portasatelites la rotation maxima del planeta y por tanto del compresor (20) y en sentido inverso al giro de la rueda. Simultaneamente, al activar esta maneta o acelerador, la electrovalvula (16) se pilota en sentido contrario, de forma que ahora conecta el deposito (2) de aire presurizado con la salida del aire del compresor (20). En este caso el gradiente de presiones hace que el aire salga del deposito (2) y entre al compresor (20) expansionandose y haciendo girar el rotor de paletas ejerciendo ahora las funciones de motor neumatico. Este, que es solidario al eje del planeta (14) y a traves del engrane con los satelites (13) hace mover la corona (15) solidario al buje (23) y por tanto a la rueda motriz en el mismo sentido de giro que antes, pero con una rotacion inferior al del planeta (14) por lo que se produce un par de empuje superior al par del motor de paletas.When the precise cyclist helps his pedaling to overcome a greater resistance to the advance or to increase the speed of the bicycle, he activates another different lever or accelerator, which as before the hydraulic circuit slows the disk (6) that slows down the satellite-carrier axis (24) so that the greater this braking is, the greater the multiplication of the planet wheel (14) will be in solidarity with the axis of the compressor, reaching when said axis is paralyzed, the maximum rotation of the planet and therefore of the compressor (20) and in the opposite direction to the wheel rotation. Simultaneously, when activating this lever or accelerator, the solenoid valve (16) is piloted in the opposite direction, so that it now connects the reservoir (2) of pressurized air with the air outlet of the compressor (20). In this case, the pressure gradient causes the air to leave the tank (2) and enter the compressor (20) by expanding and rotating the vane rotor, now exercising the functions of a pneumatic motor. This, which is integral to the axis of the planet (14) and through the engagement with the satellites (13) moves the crown (15) integral to the hub (23) and therefore to the driving wheel in the same direction of rotation as before , but with a rotation lower than that of the planet (14), so that a torque greater than the torque of the vane motor is produced.
En el caso de que el ciclista presione simultaneamente la maneta de frenado y la maneta de aceleracion el conmutador electrico (22) quedarla sin activarse y por tanto la electrovalvula no tendrla pilotaje quedando en position de centros cerrados y no realizando ninguna de las dos funciones de frenado ni de acelerador.In the event that the cyclist simultaneously presses the brake lever and the acceleration lever, the electric switch (22) is not activated and therefore the solenoid valve will not have the pilot staying in the position of closed centers and not performing any of the two functions of braking or accelerator.
Un dispositivo de freno regenerativo neumatico segun la invention comprende un compresor neumatico (20) de paletas radiales (21) que es movido por la rueda motriz de la bicicleta a traves de un sistema de engranajes planetarios que multiplica su rotacion en funcion de las exigencias de frenado impuestas por el ciclista, de forma tal que el compresor comprime el aire ambiente y lo conduce a traves de una electrovalvula (16) a un deposito de aire comprimido (2) que circunda el buje (23) de la rueda, donde es almacenado para su posterior descarga y ayuda al pedaleo a voluntad del ciclista. Cuando el ciclista necesita de la energla neumatica almacenada, para superar una mayor resistencia al avance o incrementar la velocidad, o ambos, el ciclista cambia el pilotaje de la electrovalvula (16) mediante el conmutador electrico (22), y el aire comprimido es conducido en sentido inverso desde el deposito (2) a traves de electrovalvula (16) hasta el compresor de paletas (20) donde este aire es expandido haciendo ahora girar al rotor de paletas (21) en el mismo sentido que antes y por tanto haciendo ahora la funcion de motor neumatico, cuyo eje es solidario con la rueda planeta (14) que a traves de losA pneumatic regenerative brake device according to the invention comprises a pneumatic compressor (20) of radial vanes (21) that is moved by the driving wheel of the bicycle through a planetary gear system that multiplies its rotation according to the demands of braking imposed by the cyclist, so that the compressor compresses the ambient air and drives it through an electrovalve (16) to a reservoir of compressed air (2) that surrounds the hub (23) of the wheel, where it is stored for later download and help pedaling at will of the cyclist. When the cyclist needs the stored pneumatic energy, to overcome a greater resistance to the advance or increase the speed, or both, the cyclist changes the pilot of the solenoid valve (16) by means of the electric switch (22), and the compressed air is conducted in the reverse direction from the tank (2) through solenoid valve (16) to the vane compressor (20) where this air is expanded by now rotating the vane rotor (21) in the same direction as before and therefore doing now the pneumatic motor function, whose axle is integral with the planet wheel (14) that through the

satelites (13) del mismo tren planetario, mueve de forma mas lenta a la rueda corona (15) solidaria al buje de la rueda (23), incrementado asi el par motor que se entrega a la rueda motriz como ayuda al pedaleo. El conmutador electrico (22) es activado en un sentido al presurizar el fluido hidraulico desde la maneta de freno, o activado en el sentido opuesto, al presurizar el fluido hidraulico con la maneta de acelerador.satellites (13) of the same planetary train, move more slowly to the crown wheel (15) integral to the wheel hub (23), thus increasing the torque delivered to the driving wheel to help pedaling. The electric switch (22) is activated in one direction by pressurizing the hydraulic fluid from the brake lever, or activated in the opposite direction, by pressurizing the hydraulic fluid with the throttle lever.
El propio dispositivo de freno regenerativo neumatico segun la invencion puede ser empleado en otro tipo de vehiculo no autopropulsado distinto a la bicicleta, en el que la ayuda sea al pedaleo; o a otro tipo de mecanismo de accionamiento muscular.The pneumatic regenerative brake device according to the invention can be used in another type of non-self-propelled vehicle other than the bicycle, in which the aid is pedaling; or to another type of muscular drive mechanism.
Asimismo, la energia neumatica almacenada por medio del dispositivo de freno regenerativo neumatico segun la invencion, tambien puede ser para ayudar al motor de cualquier otro tipo de vehiculo autopropulsado.Likewise, the pneumatic energy stored by means of the pneumatic regenerative brake device according to the invention can also be to help the engine of any other type of self-propelled vehicle.
El circuito de presion de aire tiene una valvula limitadora de presion de tarado variable en funcion de las caracteristicas resistentes del deposito (2) y del compresor de paletas (20) de forma que se evite poner en riego de rotura estos elementos o sus conductos por presion excesiva.The air pressure circuit has a variable tare pressure limiting valve depending on the resistant characteristics of the tank (2) and the vane compressor (20) so that these elements or their ducts are not irrigated by breakage excessive pressure.
