Description
TITULO TITLE
APARATO DINAMOGENICO PARA APRIETE-DESAPRIETE DE TUERCAS O PERNOS DE RUEDAS DE VEHICULOS. DYNAMOGENIC DEVICE FOR TIGHTENING-DISAPPEARING NUTS OR BOLTS OF VEHICLE WHEELS.
DESCRIPCION La presente invención se encuentra referida a un aparato dinamogénico para facilitar la operación de aprietedesapriete de tuercas o pernos de fijación de las ruedas de vehículos, especialmente de vehículos pesados, a efectos del recambio de dichas ruedas. DESCRIPTION The present invention relates to a dynamic apparatus for facilitating the operation of tightening nuts or bolts for fixing the wheels of vehicles, especially heavy vehicles, for the purpose of replacing said wheels.
Es conocida la gran dificultad que entraña la sustitución de las ruedas en vehículos pesados, especialmente cuando el recambio ha de realizarse por el propio usuario en condiciones poco favorables, por ejemplo, en la carretera y consiguientemente lejos de talleres mecánicos, de manera que la mencionada operación de aprietedesapriete de las tuercas debe realizarse con el empleo de herramientas estrictamente manuales, tales como llaves, palancas, etc. The great difficulty involved in replacing the wheels in heavy vehicles is known, especially when the spare part has to be carried out by the user in unfavorable conditions, for example, on the road and consequently far from mechanical workshops, so that the aforementioned Tightening operation of the nuts must be done with the use of strictly manual tools, such as wrenches, levers, etc.
En la técnica actual son ya conocidos dispositivos y aparatos a base de engranajes que constituyen un elemento mecánico para apriete-desapr iete de las referidas tuercas o pernos. No obstante, en los dispositivos conocidos, continúa siendo necesaria la aplicación de un gran esfuerzo, ya que la multiplicación conseguida mediante los precitados engranajes es muy limitada. In the present technique, gear-based devices and devices are already known which constitute a mechanical element for tightening-disengaging of said nuts or bolts. However, in the known devices, the application of a great effort is still necessary, since the multiplication achieved by means of the aforementioned gears is very limited.
Se conocen también, ciertos mecanismos a modo de gatos, es decir, basados en el principio tuerca-husillo, que resultan muy voluminosos, de manera que son de difícil ubicación y transporte en los vehículos.
Es también conocido por medio de la solicitud de patente española número 9002263, también a nombre del ahora solicitante, un aparato para atornillado-desatornillado de tuercas, constituido por una pareja de engranajes acoplados mediante una cadena de transmisión, que permite paliar, tan solo en parte, el mencionado problema. Certain mechanisms are also known as cats, that is, based on the nut-spindle principle, which are very bulky, so that they are difficult to locate and transport in vehicles. It is also known through the Spanish patent application number 9002263, also in the name of the now applicant, an apparatus for screwing-unscrewing nuts, consisting of a pair of gears coupled by a transmission chain, which allows palliation, only in part, the mentioned problem.
Es pues proposito de la invención, el desarrollo de un aparato dinamogénico que permita llevar a cabo la mencionada operación de apriete-desapriete de tuercas o pernos de vehículos con un mínimo esfuerzo, de manera que resulte incluso aplicable en situaciones desfavorables como por ejemplo, en la carretera, y que además sea de fácil y económica fabricación y manejo. It is therefore the purpose of the invention, the development of a dynamic apparatus that allows the aforementioned operation of tightening-loosening of nuts or bolts of vehicles with a minimum effort, so that it is even applicable in unfavorable situations such as, for example, in the road, and also easy and economical manufacturing and handling.
Según la invención esta tarea se consigue, por cuanto el mencionado aparato que está sustancialmente constituido por una llave o eje en cuyo extremo tiene un cubillo o cazoleta para acoplamiento a la cabeza de la tuerca; este eje dispone en el extremo opuesto una zona estriada, donde puede ser encajado o desencajado sin más que desplazarse en sentido axial una palanca en uno de cuyos extremos dispone de un agujero estriado interiormente que es quien puede encajar en la zona estriada del eje. En el otro extremo ésta palanca dispone de un agujero ranurado donde se aloja el bulón de reacción de la palanca motriz que dispone así mismo de otro bulón más cercano al eje de la llave que actúa como punto de apoyo. According to the invention this task is achieved, in that said apparatus which is substantially constituted by a key or shaft at the end of which has a hub or bowl for coupling to the head of the nut; This axis has at the opposite end a grooved area, where it can be fitted or disengaged without moving in a axial direction a lever in one of whose ends has an internally grooved hole that is the one who can fit in the grooved area of the shaft. At the other end, this lever has a slotted hole where the reaction lever of the drive lever is housed, which also has another bolt closer to the axis of the key that acts as a support point.
El bulón de punto de apoyo se aloja en otro agujero que dispone en su extremo otra doble palanca cuyo cometido es que uno de los brazos o prolongador de la misma se apoye en un punto fijo mientras el otro extremo, opuesto diametralmente, es el que dispone del agujero donde se aloja el bulón de punto de apoyo, mientras en su parte central dispone de un casquillo que se sitúa por el exterior al eje de la llave y que le permite girar el conjunto de las dos
palancas . The bolt of support point is housed in another hole that has at its end another double lever whose task is that one of the arms or extension thereof is supported on a fixed point while the other end, diametrically opposed, is the one that has of the hole where the bolt of support point is housed, while in its central part it has a bushing that is located on the outside of the axis of the key and that allows it to rotate the set of the two levers
Al accionar la palanca motriz ésta gira sobre el bulón de punto de apoyo empujando por medio del bulón alojado en el agujero ranurado a la palanca a través de la cual se hace girar al eje por estar encajada en la zona ranurada. When the drive lever is actuated, it rotates on the pin of support point by pushing through the bolt housed in the slotted hole to the lever through which the shaft is rotated by being fitted in the grooved area.
Por la relación entra los brazos de palanca entre el punto de accionamiento y punto de apoyo y la distancia entre los dos bulones así como la de estos al eje de la llave, el par de accionamiento queda multiplicado por el factor deseado. By the relationship between the lever arms between the actuation point and support point and the distance between the two bolts as well as that of these to the axis of the key, the driving torque is multiplied by the desired factor.
Otras características y ventajas de la invención, resultarán más claramente de la siguiente descripción, realizada con la ayuda de los dibujos anexos, relativos a un ejemplo de ejecución no limitativo y en los que las figuras 1 a 3, muestran vistas en planta superior y alzados laterales de un aparato dinamogénico para apriete-desapriete de tuercas o pernos según la invención.
