Description

Dispositivo direccional para remolques.Directional device for trailers.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un dispositivo direccional para remolques, y mas concretamente a un medio comandado mecánica e hidráulicamente para proporcionar una adecuado direccionamiento a las ruedas traseras de un remolque.The present invention relates to a directional device for trailers, and more specifically to a half mechanically and hydraulically commanded to provide a adequate addressing to the rear wheels of a trailer.

El objeto de la invención es conseguir un eficaz direccionamiento de las ruedas posteriores de un remolque arrastrado por un vehículo tractor, en combinación y sincronizadamente con el giro del propio tractor de arrastre.The object of the invention is to achieve an effective  addressing the rear wheels of a trailer dragged by a tractor vehicle, in combination and synchronously with the rotation of the tow tractor itself.

Antecedentes de la invenciónBackground of the invention

Como es sabido, los remolques agrícolas son arrastrados por un tractor, teniendo aquellos un eje delantero direccionable unido a una lanza a través de la cual se acopla o conecta al propio vehículo tractor, de manera que cuando éste toma una curva, la lanza bascula lateralmente y bascula también el eje delantero del remolque, siguiendo mas o menos la trayectoria del tractor.As is known, agricultural trailers are dragged by a tractor, those having a front axle addressable attached to a lance through which it is coupled or connects to the tractor vehicle itself, so when it takes a curve, the lance tilts laterally and also tilts the axis front of the trailer, more or less following the trajectory of the tractor.

No obstante, las ruedas posteriores son arrastradas en ese giro y se produce un gran desgaste de las mismas.However, the rear wheels are dragged in that turn and great wear of the same.

Para solucionar ese problema se conocen remolques en los que el eje trasero es basculante, es decir que se hacen direccionables las ruedas traseras, al objeto de que el remolque tome mejor las curvas, limitando con ello el arrastre de las ruedas posteriores, con el consecuente menor desgaste para las mismas. Es decir, un remolque con ruedas traseras direccionables funciona mejor desde el punto de vista direccional, siendo ese direccionamiento de las ruedas traseras lo que permite efectuar curvas muy cerradas sin que se produzca desplazamiento transversal de las ruedas, que es lo que desgasta las mismas.To solve that problem they know trailers in which the rear axle is tilting, that is to say make the rear wheels addressable, so that the tow better take the curves, thereby limiting the drag of the rear wheels, with the consequent less wear for same. That is, a trailer with addressable rear wheels it works better from the directional point of view, being that addressing of the rear wheels allowing to perform very sharp curves without transverse displacement of the wheels, which is what wears them out.

Pues bien, aunque se conocen sistemas y dispositivos que son aplicados al eje trasero de un remolque para establecer el direccionamiento de éste y evitar con ello el desgaste de las ruedas posteriores, sin embargo el funcionamiento se basa en medios electrónicos que son complejos y de coste económico muy elevado.Well, although systems are known and devices that are applied to the rear axle of a trailer to establish the address of the latter and thereby avoid rear wheel wear, however operation It is based on electronic media that are complex and cost effective Very high economic.

Descripción de la invenciónDescription of the invention

El dispositivo que se preconiza presenta la particularidad de constituir un elemento hidráulico-mecánico de direccionamiento de las ruedas posteriores de un remolque.The device that is recommended presents the particularity of constituting an element hydraulic-mechanical addressing of the rear wheels of a trailer.

Mas concretamente el dispositivo de la invención se basa en una válvula distribuidora asociada a dos válvulas antiretorno que se relacionan con el correspondiente equipo hidráulico del vehículo tractor de arrastre, de manera tal que esa válvula distribuidora es accionada a partir de un cable de mando que por un extremo se une a una palanca articulada a un tirante como medio de regulación para ajustar el propio cable, que por su otro extremo se relaciona con una palanca de actuación de la propia válvula distribuidora, estando ésta solidarizada a la correspondiente barra de dirección que une las dos manguetas del eje direccional de las ruedas traseras del vehículo. De esta forma, a partir de esa válvula de distribución se actúa sobre un cilindro que es el que está relacionado, a través de su correspondiente vástago, con una de las manguetas laterales de dirección, de forma tal que dependiendo del sentido de giro del vehículo tractor, el correspondiente accionamiento del cable llevará consigo el oportuno accionamiento, a través de la válvula de distribución, del cilindro direccional, y con ello el giro en un sentido u otro, contrario al del vehículo tractor, de las propias ruedas posteriores del remolque. Es decir que si el vehículo tractor gira a derechas el eje direccional de las ruedas traseras girará a izquierdas para que el remolque lleve a cabo su desplazamiento hacia la derecha, con la particularidad de que el ángulo de giro del eje del remolque será proporcional al giro del tractor.More specifically the device of the invention It is based on a distributor valve associated with two valves non-return that relate to the corresponding equipment hydraulic of the tow tractor, so that distributor valve is actuated from a control cable which at one end joins a lever articulated to a tie rod as a means of regulation to adjust the cable itself, which by its other end is related to a lever of action of the own distribution valve, this being in solidarity with the corresponding steering bar connecting the two sleeves of the directional axle of the rear wheels of the vehicle. Thus, from that distribution valve it acts on a cylinder which is the one that is related, through its corresponding shank, with one of the side steering sleeves, so such that depending on the direction of rotation of the tractor vehicle, the corresponding cable drive will carry the appropriate actuation, through the distribution valve, of the cylinder directional, and with it the turn in one direction or another, contrary to of the tractor vehicle, of the rear wheels of the trailer. That is to say that if the tractor vehicle turns right the directional axle of the rear wheels will turn left so that the trailer will move to the right, with the particularity that the angle of rotation of the trailer axle will be proportional to the turn of the tractor.

En definitiva se trata de un dispositivo que permite comandar mecánica e hidráulicamente y sin componentes electrónicos de ningún tipo, el eje trasero de las ruedas de un remolque.It is definitely a device that allows to command mechanically and hydraulically and without components electronic of any kind, the rear axle of the wheels of a trailer.

Asimismo, en base al dispositivo referido se evita el arrastre de esas ruedas posteriores, en virtud de que el cable de mando se ajusta con el propio vehículo tractor y el remolque en línea recta, puesto que en base a ese cable la válvula distribuidora se mantiene en su posición central, de ahí el ajuste que se consigue en línea recta entre el tractor y el remolque.Also, based on the device referred to prevents the dragging of these rear wheels, because the control cable fits with the tractor vehicle itself and the straight line trailer, since based on that cable the valve distributor remains in its central position, hence the adjustment which is achieved in a straight line between the tractor and the trailer.

También se consigue que en base al dispositivo y de acuerdo con los dicho con anterioridad, las ruedas se mantendrán fijas cuando se circula en línea recta.You also get that based on the device and according to those said before, the wheels will remain fixed when driving in a straight line.

Por último decir que el circuito cerrado a presión correspondiente al sistema hidráulico, garantiza la precisión del dispositivo al no existir fugas.Finally say that the closed circuit to pressure corresponding to the hydraulic system, guarantees the device accuracy in the absence of leaks.
