Description

"CARRO TRACTOR CON LEVA INCORPORADA" "TRACTOR CAR WITH INCORPORATED CAM"
DESCRIPCIÓNDESCRIPTION
La invención se refiere a un carro tractor con leva incorporada aplicable a sistemas mecánicos en los que un panel móvil describe una serie de movimientos tales como abatimiento y/o deslizamiento, especialmente estudiado para techos abrientes en automoción.The invention relates to a tractor car with built-in cam applicable to mechanical systems in which a mobile panel describes a series of movements such as abatement and / or sliding, especially studied for automotive roofs.
En la actualidad se conocen diferentes sistemas encaminados a originar el movimiento de abatimiento y/o deslizamiento de un panel móvil.At present, different systems are known to cause the movement of abatement and / or sliding of a mobile panel.
Unos incorporan un cilindro seguidor fijado al carro y otra pieza fijada al panel móvil, una luna por ejemplo, la cual tiene un coliso tallado, leva, de tal modo que al recorrer el cilindro seguidor dicha leva, se llevan a cabo los movimientos del panel móvil.Some incorporate a follower cylinder fixed to the car and another part fixed to the mobile panel, a moon for example, which has a carved collision, cam, so that when the follower cylinder travels said cam, the movements of the panel are carried out mobile.
Otros sistemas, además de las piezas anteriores incorporan una biela cuya misión es la de, mediante un giro, realizar algunos de los movimientos requeridos, consiguiendo así que la leva no precise tener tallado todo el recorrido.Other systems, in addition to the previous pieces incorporate a connecting rod whose mission is to, by means of a turn, perform some of the required movements, thus ensuring that the cam does not need to have the entire route carved.
En otros sistemas, el carro tractor no tiene un seguidor sino una pinza que abraza al perfil de la pieza fijada a la luna y recorre longitudinalmente un camino predeterminado por dicho perfil, que hace las funciones de leva.In other systems, the tractor car does not have a follower but a clamp that hugs the profile of the part fixed to the moon and travels longitudinally a path predetermined by said profile, which functions as a cam.
Todos estos sistemas están concebidos para utilizar sirga como elemento motriz de los carros.All these systems are designed to use serve as the driving element of the cars.
- Los sistemas citados que incluyen únicamente leva requieren un espacio considerable entre la piel exterior y el guarnecido de techo, puesto que la altura de la leva es igual a la diferencia de cotas verticales del panel. El brazo leva debe estar dotado de sobreinyecciones en plástico a fin de evitar el contacto metal-metal entre la leva y el seguidor.- The mentioned systems that include only cam require a considerable space between the outer skin and the roof trim, since the height of the cam is equal to the difference in vertical dimensions of the panel. The cam arm must be provided with plastic overinjections in order to avoid metal-metal contact between the cam and the follower.
Las zonas por las que se desliza el carro sobre el soporte deben ser sobreinyectadas en plástico o, en su caso, se les debe añadir piezas plásticas en un proceso posterior con el fin de permitir el deslizamiento sobre el soporte metálico.The areas through which the carriage slides on the support must be overinjected in plastic or, where appropriate, plastic parts must be added in a subsequent process in order to allow sliding on the metal support.
Por otro lado, los carros actuales están diseñados para circular por el interior del soporte en canales diseñados a tal efecto, es decir, son abrazados por el soporte.On the other hand, current cars are designed to circulate inside the support in channels designed for this purpose, that is, they are embraced by the support.
En todos ellos la altura conseguida con el abatimiento del panel es escasa.In all of them the height achieved with the panel abatement is low.
Frente a estas técnicas conocidas, la invención tiene como objeto un carro tractor de una sola pieza en la cual se integran el máximo número de funciones y componentes de un techo abriente.In the face of these known techniques, the object of the invention is a one-piece tractor car in which the maximum number of functions and components of an open roof are integrated.
Es otro objeto de la invención un carro tractor que permite reducir en forma notable la altura del mecanismo para así disminuir el espacio libre entre la piel exterior y el guarnecido de techo del vehículo.Another object of the invention is a tractor car that allows the height of the mechanism to be significantly reduced in order to reduce the clearance between the outer skin and the roof trim of the vehicle.
Es otro objeto de la invención un carro tractor que a igualdad del dicho espacio libre, permite mayores abatimientos del panel móvil.It is another object of the invention a tractor car that, equal to said free space, allows greater depletion of the mobile panel.
Es otro objeto de la invención un carro de mayor versatilidad que no está limitado a tracción mediante sirga sino que puede ser adaptado a distintos sistemas de tracción.Another object of the invention is a car of greater versatility that is not limited to traction by means of a rope but can be adapted to different traction systems.
Para alcanzar estos objetivos, el carro según la invención es un cuerpo único obtenido por inyección en uno de cuyos laterales longitudinales se destaca una ranura a modo de leva compuesta por tres tramos bien diferenciados. Un tramo central que es paralelo al soporte determinante de la posición de cerrado del panel móvil. Los otros dos tramos determinan a su vez las posiciones de abatimiento y deslizamiento del citado panel móvil.To achieve these objectives, the carriage according to the invention is a single body obtained by injection in one of whose longitudinal sides, a cam-shaped groove composed of three distinct sections is highlighted. A central section that is parallel to the support determining the closed position of the mobile panel. The other two sections, in turn, determine the folding and sliding positions of said mobile panel.
Por debajo de la leva y en forma sobresaliente, el carro dispone de una aleta longitudinal a modo de ballesta realizada en la misma inyección la cual tiene como finalidad la de absorber las posibles tolerancias del soporte sobre el que va montado el carro, ya que se adapta al mismo sin holguras ni generación de ruidos y vibraciones, que se originan con el movimiento del vehículo en las técnicas conocidas.Below the cam and in an outstanding way, the carriage has a longitudinal flap as a crossbow made in the same injection which has the purpose of absorbing the possible tolerances of the support on which the carriage is mounted, since it adapts to it without gaps or noise and vibration generation, which originate with the movement of the vehicle in known techniques.
El carro cuenta con unas patillas por la cara longitudinal opuesta a la de la leva, las que se encargan de sujetar dicho carro al soporte sobre el que circula e impedir movimientos verticales excesivos que pudieran provocar el desensamblaje del sistema.The carriage has some pins on the longitudinal side opposite to that of the cam, which are responsible for securing said carriage to the support on which it circulates and preventing excessive vertical movements that could cause disassembly of the system.
Las patillas están rematadas por unas uñas encargadas de sujetar el carro y los distintos elementos anclados a él, impidiendo que se muevan verticalmente más allá de la holgura con la que se han diseñado.The pins are topped by nails responsible for holding the car and the various elements anchored to it, preventing them from moving vertically beyond the clearance with which they have been designed.
Las uñas en cuestión son discontinuas, y se corresponden con las posiciones de entrantes practicados en una pared horizontal del propio soporte de modo que el carro se monta en vertical sobre el dicho soporte pasando las uñas por los entrantes para, posteriormente, mediante un sencillo movimiento del carro hacia el frontal del soporte engarzar y disponer los carros para su movimiento de servicio.The nails in question are discontinuous, and correspond to the positions of recesses made in a horizontal wall of the support itself so that the carriage is mounted vertically on said support passing the nails through the recesses for, subsequently, by a simple movement from the carriage to the front of the support to crimp and arrange the carriages for its service movement.
En cada carro, las zonas de leva y ballesta y de dientes y uñas están separadas en paralelo y a una cierta distancia procurando un espacio ranurado para la inserción del medio de traslación del carro de que se trate, bien sea éste un cable o una sirga.In each car, the cam and crossbow and tooth and nail areas are separated in parallel and at a certain distance, providing a slotted space for the insertion of the means of translation of the car in question, be it a cable or a rope.
La cara inferior de los carros es plana superficialmente y en ella se destacan unas protuberancias longitudinales con las cuales se garantiza un mejor apoyo sobre la superficie del soporte sobre el que desliza el carro así como un mejor deslizamiento. El carro es inyectado en plástico en su totalidad y en caso necesario el diseño permite el acoplamiento de refuerzos metálicos, bien sobreinyectados bien unidos mecánicamente.The underside of the cars is superficially flat and it features longitudinal protrusions with which a better support is guaranteed on the surface of the support on which the carriage slides as well as a better slide. The car is injected in plastic in its entirety and if necessary the design allows the coupling of metal reinforcements, well overinjected well mechanically joined.
Las hojas de planos representan una solución práctica de la invención, según se relaciona a continuación.The sheets of planes represent a practical solution of the invention, as listed below.
-La Figura 1, es una perspectiva de uno de los carros de la invención del lado interior de uno de los laterales del marco soporte.-Figure 1 is a perspective of one of the cars of the invention on the inner side of one of the sides of the support frame.
-La Figura 2, es otra perspectiva del carro de la fig. 1, tomada desde su cara inferior.-Figure 2 is another perspective of the car of fig. 1, taken from its lower face.
-La Figura 3, es un corte transversal del carro.-Figure 3 is a cross section of the car.
-La Figura 4, es una perspectiva del extremo del marco soporte por el que discurrirá el carro, descrito en plan general, del lado de las patillas.-Figure 4 is a perspective of the end of the support frame through which the carriage, described in general plan, will run along the side of the pins.
Según la fig. 1, apreciamos el carro (A) con una porción delantera, del lado del panel móvil y una porción trasera, del lado de la carrocería del techo del vehículo o elemento de que se trate.According to fig. 1, we appreciate the carriage (A) with a front portion, on the side of the mobile panel and a rear portion, on the body side of the roof of the vehicle or item in question.
La porción delantera incluye la leva (1) con sus tres tramos clásicosThe front portion includes the cam (1) with its three classic sections
(V, 1", 1 '") y por debajo de ella y sobresaliendo la configuración a modo de ballesta (2) encargada de absorber las posibles tolerancias del soporte sobre el que va montado el carro. Esta ballesta se configura en un plano horizontal de actuación mecánica, tal y como se advierte en esta fig. 1.(V, 1 ", 1 '") and below it and protruding the configuration as a crossbow (2) responsible for absorbing the possible tolerances of the support on which the car is mounted. This crossbow is configured in a horizontal plane of mechanical action, as shown in this fig. one.
La parte inferior de esta porción delantera establece el nexo de unión con la porción trasera, constituyendo entre ambas un espacio (5), según se aprecia en esta fig. 1.The lower part of this front portion establishes the link with the rear portion, constituting a space (5) between them, as shown in this fig. one.
Al otro lado de éste espacio, advertimos las patillas (3) en forma de L invertida que se abren hacia abajo, las cuales son las encargadas de establecer relación con los canales del marco soporte. Las patillas (3) se observan también en las figs. 2 y 3 con su posición exacta, así como las uñas de remate (4) de las mismas que se extienden en voladizo a partir de sus extremos libres en dirección paralela al brazo horizontal de las patillas. Las uñas (4), fig. 3, dejan un espacio libre (8) para su montaje.On the other side of this space, we notice the inverted L-shaped pins (3) that open downwards, which are responsible for establishing relationship with the support frame channels. The pins (3) are also seen in figs. 2 and 3 with their exact position, as well as the finishing nails (4) thereof that extend in a cantilever from their free ends in a direction parallel to the horizontal arm of the pins. The nails (4), fig. 3, leave a free space (8) for assembly.
El montaje sobre el perfil del marco soporte se realiza situando las uñas (4) sobre entrantes -ad hoc- practicados verticalmente en las paredes superiores horizontales de los canales del dicho marco, introduciendo las uñas en los entrantes hasta sobrepasar su espesor, desplazando seguidamente el carro (A) para que el espesor de las paredes quede situado por encima de las referidas uñas. Esta operación de fijación final se completa presionando el carro hacia la derecha, según la posición representada, para desplazarlo adecuadamente.The mounting on the profile of the support frame is done by placing the nails (4) on recesses -ad- vertically practiced in the horizontal upper walls of the channels of said frame, introducing the nails in the recesses until they exceed their thickness, then moving carriage (A) so that the thickness of the walls is located above said nails. This final fixing operation is completed by pressing the carriage to the right, according to the position represented, to move it properly.
Para este desplazamiento se utiliza el juego que procura el espacio de separación (8) que procuran las uñas, fíg. 3.For this displacement the game that seeks the space of separation (8) that the nails procure, fig. 3.
El espacio (5) es el que se utiliza para el paso de la eventual sirga y en su caso para la disposición de muelles y tetones cuando se utilice cable como elemento de tracción.The space (5) is the one that is used for the passage of the possible serve and, where appropriate, for the arrangement of springs and lugs when cable is used as a tensile element.
La superficie inferior (10) del carro está surcada por las protuberancias longitudinales (6) convexas hacia el exterior tal y como se define en las figs. 2 y 3. Asimismo y de estas mismas figs. apreciamos los agujeros (7) facilitadores del desmoldeo y generación de todas las paredes del mismo.The lower surface (10) of the carriage is grooved by the longitudinal protuberances (6) convex outwards as defined in figs. 2 and 3. Likewise and of these same figs. we appreciate the holes (7) to facilitate the demoulding and generation of all the walls of the same.
Tal y como con anterioridad se citaba, el carro (A) se monta sobre el marco (9) de la fig. 4 en posición vertical. Para ello, las uñas (4) se hacen coincidir con los entrantes (12) practicados en una pared horizontal (1 1), la más superior de las que constituyen las guías (10) para, seguidamente, sobrepasar el espesor de dicha pared y con una suave presión sobre el carro y hacia el soporte, encajar aquel perfectamente en el marco (9), de forma que es el carro (A) el que abraza al marco. Distribuídos a lo largo de todas las paredes del carro se disponen nervios rigidizantes de las superficies, a excepción lógicamente de aquellas que precisen de cierta flexibilidad y que previamente se hayan debilitado, por ejemplo la ballesta.As previously mentioned, the carriage (A) is mounted on the frame (9) of fig. 4 in an upright position. For this, the nails (4) are made to coincide with the recesses (12) practiced in a horizontal wall (1 1), the most superior of those that constitute the guides (10) to, then, exceed the thickness of said wall and with a gentle pressure on the carriage and towards the support, fit that perfectly into the frame (9), so that it is the carriage (A) that hugs the frame. Distributed along all the walls of the carriage are stiffening ribs of the surfaces, except logically those that require some flexibility and have previously weakened, for example the crossbow.
El carro según la invención adopta un sistema de sujeción que abraza al marco soporte, en lugar de al revés como es lo tradicional, lo cual posibilita la inexistencia de canales interiores en el marco.The carriage according to the invention adopts a fastening system that hugs the support frame, instead of the other way around as is the traditional, which allows the absence of internal channels in the frame.
Además, al ser de un único material es fácilmente reciclable, atendiendo así las más modernas tendencias de la industria en éste sentido. In addition, being a single material is easily recyclable, thus meeting the most modern trends in the industry in this regard.
