Abstract

The tube and the anchoring part are joined together by means of an upper connection and a lower connection, the latter corresponding to the lower edge of the tube. The invention is characterized in that the upper connection consists of a pressure clamping of an upper portion of the anchoring part (2) on the tube (1), two fins (3) and (4) that form part of the anchoring part (2) being secured together, to that end, in the top part, said fins guaranteeing the stability of said upper connection. On the other hand, the lower connection is produced by means of a weld bead. The securing method is notable essentially in that, during the upper connection of the anchoring part (2), pressure clamping is maintained between said anchoring part and the tube (1).

Description

UNIÓN MEJORADA ENTRE AMARRE Y TUBO DE UNA SUSPENSIÓN DE VEHÍCULOS Y PROCESO DE FIJACIÓN DE DICHA UNIÓNIMPROVED UNION BETWEEN AMARRE AND TUBE OF A VEHICLE SUSPENSION AND SUCH UNION FIXING PROCESS
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a una unión mejorada entre amarre y tubo de una suspensión de vehículos y proceso de fijación de dicha unión.The present invention, as expressed in the statement of this specification, refers to an improved connection between mooring and tube of a vehicle suspension and fixing process of said union.
La unión de la invención consiste en un monoamarre de los que se emplean en las suspensiones de los vehículos, a la vez que se fijan a las manguetas, cuya función es proporcionar una sujeción con una serie de especificaciones mecánicas mejoradas de un tubo que forma parte del amortiguador .The union of the invention consists of a mono-mooring of those used in vehicle suspensions, at the same time as they are fixed to the sleeves, whose function is to provide a fastener with a series of improved mechanical specifications of a tube that is part of the shock absorber.
Partiendo de este premisa, el objeto de la invención es una unión mejorada que evita el deterioro de las propiedades mecánicas del tubo. Para ello, se elimina una soldadura superior, que es la que disminuye estas propiedades, consiguiendo de este modo reducir el peso, el coste y aumentar en cambio la resistencia a la fatiga del subconjunto tubo-amarre.Starting from this premise, the object of the invention is an improved union that prevents the deterioration of the mechanical properties of the tube. For this, a superior weld is eliminated, which decreases these properties, thus reducing the weight, the cost and increasing the fatigue resistance of the tube-mooring subassembly.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Actualmente, en las suspensiones tipo MacPherson o pseudo MacPherson de los vehículos se utilizan módulosCurrently, modules are used in MacPherson or pseudo MacPherson type suspensions of vehicles
(amortiguador, plato, soporte muelle, muelle y soporte superior) para asegurar la unión entre el conjunto masa no suspendida (rueda, pivote, freno) y la masa suspendida(shock absorber, plate, spring support, spring and upper support) to ensure the union between the mass not suspended (wheel, pivot, brake) and the suspended mass
(caj a del coche) .(car box).
En consecuencia, el módulo está sometido a esfuerzos longitudinales, transversales y verticales. Para soportar estos esfuerzos se necesitan características mecánicas del subconjunto tubo-amarre que aguanten las especificaciones de los constructores de automóviles.Consequently, the module is subjected to longitudinal, transverse and vertical stresses. To withstand these efforts, mechanical characteristics of the tube-mooring subset that support the specifications of car manufacturers are needed.
En los conceptos actuales de unión entre amarre y tubo se realizan dos soldaduras perimetrales, una de 360° menos un arco correspondiente a la mangueta en la parte superior de la unión entre el amarre y el tubo y otra de 360° en la parte inferior de la unión también entre el amarre y el tubo .In the current concepts of connection between mooring and tube, two perimeter welds are made, one of 360 ° minus an arc corresponding to the spindle at the top of the union between the mooring and the tube and another of 360 ° at the bottom of the union also between the mooring and the tube.
La soldadura de la parte superior debilita las propiedades mecánicas del tubo, que está sometido a los esfuerzos longitudinales y transversales.Welding of the upper part weakens the mechanical properties of the tube, which is subjected to longitudinal and transverse forces.
Para compensar la debilidad debida a la soldadura, deben utilizarse tubos de calidades superiores y/o dimensiones superiores también. Esto encarece evidentemente el producto final y/o aumenta su peso.To compensate for the weakness due to welding, tubes of higher qualities and / or higher dimensions should also be used. This obviously makes the final product more expensive and / or increases its weight.
Por otro lado, algunas suspensiones actuales incorporan amortiguadores tipo Strut de los utilizados habitualmente en vehículos automóviles en suspensiones MacPherson. El amortiguador se unirá a la mangueta a través del amarre inferior.On the other hand, some current suspensions incorporate Strut-type shock absorbers of those commonly used in motor vehicles in MacPherson suspensions. The shock absorber will be attached to the sleeve through the lower tie.
Los esfuerzos provenientes de las ruedas se transmiten al conjunto formado por el tubo y el amarre. Los esfuerzos del conjunto de caja superior también se transmiten al conjunto de tubo y amarre. Por otra parte cabe señalar que el amarre se une al tubo por medio de dos soldaduras, una en la parte superior y otra en la parte inferior. La soldadura superior debilita el tubo tal como se ha referido anteriormente, en una zona que tiene que soportar esfuerzos elevados. En consecuencia, se utilizan tubos de características mecánicas y geométricas superiores a lo que en principio seria suficiente si no se deteriorasen las propiedades mecánicas del tubo en la soldadura.The stresses coming from the wheels are transmitted to the assembly formed by the tube and the mooring. The efforts of the upper box assembly are also transmitted to the tube and tie assembly. On the other hand it should be noted that the tie is attached to the tube by means of two welds, one at the top and one at the bottom. The upper weld weakens the tube as mentioned above, in an area that has to withstand high stresses. Consequently, tubes of mechanical and geometric characteristics superior to what would in principle be sufficient if the mechanical properties of the tube in the weld were not deteriorated are used.
DESCRIPCIÓN DE LA INVENCIÓN Con el fin de alcanzar los objetivos y evitar los inconvenientes mencionados en los apartados anteriores, la invención propone una unión mejorada entre amarre y tubo de una suspensión de vehículos y proceso de fijación de dicha unión . Lo más característico de la unión es que se elimina la soldadura superior entre el amarre y el tubo, consiguiendo de este modo reducir peso y costes, así como un aumento de la resistencia a la fatiga del subconjunto tubo amarre.DESCRIPTION OF THE INVENTION In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes an improved connection between mooring and tube of a vehicle suspension and fixing process of said union. The most characteristic of the union is that the upper weld between the mooring and the tube is eliminated, getting in this way reduce weight and costs, as well as an increase in the fatigue resistance of the mooring tube subset.
Así pues, la soldadura superior que relacionaba el amarre con el tubo se sustituye por la unión de dos extremidades de las alas del amarre. De esta manera no es necesario realizar la soldadura superior del tubo al amarre y por lo tanto no se penalizan las características mecánicas del tubo.Thus, the upper weld that connected the mooring with the tube is replaced by the union of two ends of the mooring wings. In this way it is not necessary to perform the upper welding of the tube to the mooring and therefore the mechanical characteristics of the tube are not penalized.
Para optimizar las prestaciones del conjunto es necesario garantizar el correcto apriete del amarre sobre el tubo.To optimize the performance of the assembly it is necessary to guarantee the correct tightening of the mooring on the tube.
Para lograr dicho apriete se aplica un proceso de fijación, de tal modo que el amarre realice un apriete sobre el tubo. Dicho apriete se logra aplicando fuerzas en las alas del amarre en la misma dirección pero en sentidos opuestos, de tal modo que la unión o amarre entre amarre y tubo se cierra sobre el tubo logrando el apriete deseado. Una vez logrado dicho apriete se mantiene la fuerza de apriete sobre las alas del amarre y se procede a realizar los diferentes cordones de soldadura.To achieve this tightening, a fixing process is applied, in such a way that the mooring makes a tightening on the tube. Said tightening is achieved by applying forces on the wings of the mooring in the same direction but in opposite directions, such that the union or mooring between mooring and tube is closed on the tube achieving the desired tightening. Once this tightening is achieved, the clamping force is maintained on the wings of the mooring and the different welding beams are made.

Considerando la numeración adoptada en las figuras, la unión mejorada entre amarre y tubo de una suspensión de vehiculos consiste en principio en sustituir un cordón de soldadura superior que unia el tubo 1 con el amarre 2, reemplazándolo por la presión ejercida por el abrazo del amarre 2 sobre el tubo 1, asegurándose dicho abrazo mediante la unión de dos alas 3 y 4 que forman parte del amarre 2, de manera que dichas alas 3 y 4 se solidarizan entre si mediante un elemento de enganche 5 que se suelda a las citadas alas 3 y 4 del amarre 2 en una zona superior de la misma, o bien por cualquier otro tipo de unión que haga que la resistencia del conjunto sea óptima y estable.Considering the numbering adopted in the figures, the improved connection between mooring and tube of a vehicle suspension consists in principle of replacing an upper welding cord that joins the tube 1 with the mooring 2, replacing it with the pressure exerted by the clamp hug 2 on the tube 1, said hug being secured by joining two wings 3 and 4 that are part of the mooring 2, so that said wings 3 and 4 are joined together by means of a hooking element 5 that is welded to said wings 3 and 4 of mooring 2 in an upper area thereof, or by any other type of joint that makes the strength of the assembly optimal and stable.
La unión de las alas 3 y 4 del amarre 2 debe realizarse garantizando el apriete del abrazo del amarre 2 sobre el tubo 1.The connection of the wings 3 and 4 of the mooring 2 must be carried out guaranteeing the tightening of the hug of the mooring 2 on the tube 1.
Por otro lado, la unión soldada 6 del extremo inferior del tubo sobre el amarre 2 se mantiene, es decir, que esta unión inferior es convencional. En esta unión inferior existe una tapa 7 que puede ser un elemento individual como es el caso representado en las figuras, o bien puede consistir en una deformación del tubo 1 constituyendo un único elemento. En este caso, la soldadura inferior 6 seria más rápida. El proceso de fijación entre el tubo 1 y el amarre 2 se muestra en las figuras 3 a 6 y es como se describe a continuación .On the other hand, the welded joint 6 of the lower end of the tube on the mooring 2 is maintained, that is, that this lower joint is conventional. In this lower connection there is a cover 7 which can be an individual element as is the case represented in the figures, or it can consist of a deformation of the tube 1 constituting a single element. In this case, the bottom weld 6 would be faster. The fixing process between the tube 1 and the mooring 2 is shown in Figures 3 to 6 and is as described below.
Primeramente se introduce el tubo 1 y tapa 7 en el alojamiento 8 del amarre 2. Se realiza después un apriete del amarre 2 sobre el tubo 1 y se unen las alas 3 y 4 del amarre 2 en su parte superior mediante la soldadura del elemento de enganche 5, o bien mediante otro tipo de unión. Posteriormente se suelda el amarre 2, el tubo 1 y la tapa 7 en su parte inferior. Por último se completarían las soldaduras del resto del conjunto.Firstly, the tube 1 and cover 7 are introduced in the housing 8 of the mooring 2. Then, a tightening of the mooring 2 is carried out on the tube 1 and the wings 3 and 4 of the mooring 2 are joined in its upper part by welding the hook 5, or by another type of joint. Subsequently, the mooring 2, the tube 1 and the cover 7 are welded at the bottom. Finally the welds of the rest of the set would be completed.
El apriete del amarre 2 sobre el tubo 1 se realiza mediante un dispositivo de apriete 9 que presiona sobre las alas 3 y 4 manteniéndose la presión hasta finalizar todas las soldaduras. The tightening of the mooring 2 on the tube 1 is carried out by means of a clamping device 9 that presses on wings 3 and 4 maintaining the pressure until all the welds are finished.
