Eje de ruedaWheel axle

Objeto de la invenciónObject of the invention

La presente memoria descriptiva se refiere, como su título indica, a un eje de rueda especialmente indicado para el acoplamiento de un buje con rodamientos cónicos, interior y exterior, cuyos diámetros interiores sean diferentes, comprendiendo dicho eje de rueda un asiento axial, contra el que se apoya el rodamiento exterior, lo que permite controlar la fuerza que llega al rodamiento en el apriete, a tope, de la tuerca del eje de rueda, lo que hace que en la práctica, el rodamiento trabaje con precarga, aumentando su vida útil y reduciendo los ciclos de mantenimiento.The present specification refers, as its title indicates, to a wheel axle specially indicated for the coupling of a bushing with tapered bearings, inner and outer, whose inner diameters are different, said wheel axle comprising an axial seat, against the that supports the outer bearing, which allows to control the force that reaches the bearing in the tightening, to stop, of the nut of the wheel axle, which makes that in practice, the bearing works with preload, increasing its useful life and reducing maintenance cycles.

Antecedentes de la invenciónBACKGROUND OF THE INVENTION

Actualmente los ejes de rueda dispuestos para el acoplamiento de un buje con rodamientos cónicos, no disponen de un asiento axial, lo que dificulta el control de la holgura durante el apriete de la tuerca del eje, por lo tanto, se realiza el apriete con la tuerca del eje, a tope, para posteriormente quitar un cuarto de vuelta o media vuelta para dejar un montaje donde los rodamientos trabajan con holgura, con el inconveniente de que al perder este ajuste, la tuerca tiende a liberarse con más facilidad, lo que implica tener que pasar el camión por el taller para ajustar de nuevo la holgura inicial.Currently the wheel axes arranged for the coupling of a hub with tapered bearings, do not have an axial seat, which makes it difficult to control the slack during the tightening of the axle nut, therefore, the tightening is performed with the nut of the shaft, to stop, to later remove a quarter of a turn or half turn to leave a mounting where the bearings work with slack, with the disadvantage that when losing this adjustment, the nut tends to be released more easily, which implies have to pass the truck through the workshop to adjust the initial slack again.

El mayor inconveniente de este tipo de montajes con rodamientos cónicos, es que al no poderse controlar la holgura de montaje, se deja normalmente más holgura, lo que reduce considerablemente la vida útil de los rodamientos y aumentando el desgaste de los neumáticos y los frenos.The biggest drawback of this type of assemblies with tapered bearings, is that as the mounting clearance can not be controlled, more clearance is normally left, which considerably reduces the service life of the bearings and increases the wear of the tires and brakes.

Descripción de la invenciónDescription of the invention

Para solventar la problemática existente en la actualidad se ha ideado un eje de rueda configurado con diferentes diámetros de ajuste, que comprende un asiento axial, previsto para el acoplamiento de un buje con rodamientos cónicos.To solve the problem currently existing, a wheel axle configured with different adjustment diameters has been devised, comprising an axial seat, provided for the coupling of a hub with tapered roller bearings.

El eje de rueda, con asiento axial, está previsto para el montaje de bujes cuyos rodamientos cónicos, se configuran con el diámetro interior de diferentes dimensiones mediante un procedimiento de montaje comprendido porThe axle of wheel, with axial seat, is provided for the assembly of bushings whose tapered bearings, are configured with the internal diameter of different dimensions by a mounting procedure comprised by

una fase de acoplamiento del buje siendo quea coupling phase of the bushing being that

• cuando el rodamiento exterior llega a hacer tope con el apoyo axial, se establece una holgura mayor de “0” entre los rodamientos exterior e interior integrados en el buje.• when the outer bearing reaches the axial bearing stop, a greater clearance of "0" is established between the outer and inner bearings integrated in the bushing.

y una fase de apriete siendo queand a tightening phase being that

• cuando se realiza el par de apriete de la tuerca del eje de rueda, se genera una precarga de trabajo en los rodamientos integrados en el buje.• when the tightening torque of the wheel axle nut is carried out, a work preload is generated in the bearings integrated in the bushing.

El asiento axial es el apoyo del rodamiento exterior del buje, de modo que se realiza el apriete de la tuerca del eje de rueda, hasta el tope, según el par de apriete fijado para su perfecto funcionamiento.The axial seat is the support of the outer bearing of the bushing, so that the tightening of the nut of the wheel axle is made, up to the stop, according to the tightening torque set for its perfect operation.

El par de apriete es variable, y se aplica según las dimensiones de los rodamientos, que oscilan entre los 200 y 1500 N/m.The tightening torque is variable, and is applied according to the dimensions of the bearings, which range between 200 and 1500 N / m.

Al realizarse el par de apriete, una vez fijado el acoplamiento del rodamiento exterior del buje en el asiento axial, la holgura queda establecida en “0”, y conforme se aplica más tensión al par de apriete, se elimina la holgura pasando a valores de precarga, lo que hace que el rodamiento trabaje con una precarga entre 1000 y 5000 N, aumentando su vida útil y reduciendo los ciclos de mantenimiento.When the tightening torque is achieved, once the coupling of the outer bearing of the bushing has been fixed in the axial seat, the clearance is set to "0", and as more tension is applied to the tightening torque, the clearance is eliminated, changing to values of preload, which makes the bearing work with a preload between 1000 and 5000 N, increasing its life and reducing maintenance cycles.

En una realización alternativa se incorpora en la fase de acoplamiento del buje una arandela de calce en el asiento axial con la finalidad de reducir la dispersión de la anchura total del conjunto, y favorecer que los rodamientos trabajen en precarga al realizarse la fase de apriete.In an alternative embodiment, a shim washer is incorporated into the axial seat in the coupling phase of the hub in order to reduce the dispersion of the overall width of the assembly, and to encourage the bearings to work in preload when the tightening phase is carried out.

Ventajas de la invenciónAdvantages of the invention

Este eje de rueda, que se presenta, aporta la esencial ventaja de comprender un asiento axial para permitir el apriete del rodamiento cónico exterior a tope, eliminando la holgura, lo que implica que los rodamientos trabajen en precarga, lo que aumenta su vida útil, reduciendo también los ciclos de mantenimiento. This wheel axle, which is presented, provides the essential advantage of comprising an axial seat to allow the tightening of the outer tapered bearing to the top, eliminating the slack, which implies that the bearings work in preload, which increases their useful life, also reducing maintenance cycles.
