Description
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un sistema anti-tijera para camiones, cuya evidente finalidad es evitar el clásico efecto de “tijera” que The present invention relates to an anti-scissor system for trucks, whose obvious purpose is to avoid the classic "scissor" effect that
10 se produce entre la cabeza tractora de un camión y el semirremolque articulado a la misma, efecto que se produce fundamentalmente en las frenadas en curva y durante los descensos. 10 occurs between the tractor unit of a truck and the semi-trailer articulated to it, an effect that occurs mainly in curved braking and during descents.
El objeto de la invención es conseguir que el eje de The object of the invention is to achieve that the axis of
15 desplazamiento de la cabeza tractora y del semirremolque de los camiones articulados, se mantenga lo mas alineado posible, en el tipo de situaciones comentadas, variando tan solo el ángulo que se produzca por el trazado de la curva en la calzada, manteniéndose en todo momento alineados ambos desplazamientos (eje de la cabeza tractora y eje del semirremolque o carga) 15 displacement of the tractor unit and the semi-trailer of articulated trucks, stay as aligned as possible, in the type of situations mentioned, varying only the angle produced by the curve in the roadway, staying at all times aligned both displacements (axle of the tractor unit and axle of the semi-trailer or load)
20 y evitar con ello el accidente. 20 and thereby avoid the accident.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
25 Los camiones articulados, como es sabido, incluyen una cabeza tractora y un semirremolque arrastrado por la primera, de manera que ambas partes están conectadas mecánicamente entre si mediante la denominada “quinta rueda”. 25 Articulated trucks, as is known, include a tractor head and a semi-trailer dragged by the first, so that both parts are mechanically connected to each other by the so-called "fifth wheel".
Pues bien, uno de los accidentes que suele sufrir este tipo de vehículos, es el denominado “tijera” que se produce cuando entre la cabeza tractora y el semirremolque se origina un giro excesivo de los ejes de ambas partes o elementos, lo cual ocurre cuando se produce una frenada en Well, one of the accidents that this type of vehicles usually suffers, is the so-called “scissors” that occurs when an excessive rotation of the axles of both parts or elements originates between the tractor and the semi-trailer, which occurs when braking occurs in
5 curva y en descenso, en cuyo caso el semirremolque, por la inercia de su mayor peso, se precipita contra la cabeza tractora, haciendo que ésta pierda su trayectoria y en consecuencia la ingobernabilidad del vehículo, lo que desemboca en el inevitable accidente como consecuencia del conocido efecto “tijera”. Debe tenerse en cuenta que este tipo de siniestros ocurre 5 curve and in descent, in which case the semi-trailer, due to the inertia of its greater weight, rushes against the tractor, causing it to lose its trajectory and consequently the ungovernability of the vehicle, which leads to the inevitable accident as a consequence of the known "scissor" effect. It must be taken into account that this type of incident occurs
10 cuando el freno de la cabeza tractora es mas enérgico que el freno del semirremolque o carga, haciendo que éste ejerza un empuje sobre la propia cabeza tractora, desplazándola de su trayectoria. 10 when the brake of the tractor is more energetic than the brake of the semi-trailer or load, causing it to exert a push on the tractor itself, moving it from its trajectory.
Es decir, en el que caso de que el esfuerzo sobrepase la That is, in which case the effort exceeds the
15 adherencia del eje trasero de la cabeza tractora, y al producirse en un momento en el que no están completamente alineados los ejes de desplazamiento, por estar tomando una curva, el empuje de la carga o semirremolque, desalineado frente al eje de desplazamiento de la cabeza tractora, hace que ésta se desplace de su eje trasero hacia el lado exterior de 15 adhesion of the rear axle of the tractor unit, and when it occurs at a time when the displacement axes are not completely aligned, because of taking a curve, the thrust of the load or semi-trailer, misaligned in front of the axis of displacement of the tractor unit, makes it move from its rear axle to the outer side of
20 la curva, produciéndose el indeseado y comentado efecto “tijera”. 20 the curve, producing the unwanted and commented "scissor" effect.
Teniendo en cuenta que el sistema de la invención es aplicable Bearing in mind that the system of the invention is applicable
únicamente en aquellos vehículos con sistema de frenado ABS, a only on those vehicles with ABS braking system, to
continuación se va a describir el funcionamiento de este sistema de frenado the operation of this braking system will be described below
25 para poder comprender con mayor claridad la aplicación y funcionalidad el sistema anti-tijera de la invención. 25 in order to understand more clearly the application and functionality of the anti-scissor system of the invention.
En tal sentido y como es sabido, el sistema de frenado ABS funciona comparando en cada instante la velocidad de giro de cada una de In this sense and as is known, the ABS braking system works by comparing at each moment the speed of rotation of each of
las ruedas del vehículo que lo instala, y las compara entre si, para asegurar the wheels of the vehicle that installs it, and compares them to each other, to ensure
que se mantenga la misma en todo momento, con la particularidad de que en aquel caso en que esa velocidad de giro no sea la misma en un momento determinado, porque una de las ruedas haya sido bloqueada por el freno, hace que el sistema de frenado ABS pierda efectividad en la rueda 5 bloqueada, ya que el coeficiente de rozamiento estático es mayor que el dinámico, actuando sobre el freno de la rueda bloqueada en centésimas de segundo, haciendo perder presión a los frenos de dicha rueda, que al quedar libre vuelve a conseguir adherencia con el asfalto, recuperando su trazado angular y acompasándose con el resto de las ruedas, momento en el cual el that the same is maintained at all times, with the particularity that in that case in which that speed of rotation is not the same at a given time, because one of the wheels has been blocked by the brake, causes the braking system ABS loses effectiveness in the locked wheel 5, since the coefficient of static friction is greater than the dynamic one, acting on the brake of the locked wheel in hundredths of a second, causing the brakes of said wheel to lose pressure, which when released becomes free to achieve adhesion with the asphalt, recovering its angular layout and adjusting with the rest of the wheels, at which time the
10 sistema de frenado ABS vuelve a la siguiente centésima de segundo a actuar sobre el freno y proseguir con la detención del vehículo. 10 ABS braking system returns to the next hundredth of a second to act on the brake and continue to stop the vehicle.
Es evidente que al darse las condiciones para producirse este tipo de accidentes, en el momento que el sistema de frenado de la cabeza It is evident that when the conditions to occur this type of accident occur, at the time the head braking system
15 tractora es superior al del semirremolque, hace que éste se abalance sobre la cabeza tractora, de manera que si esto ocurre en un curva se descentra la trayectoria de dicha cabeza tractora y se produce el accidente, como se ha dicho y explicado con anterioridad. The tractor unit is superior to that of the semi-trailer, which makes it fall on the tractor head, so that if this occurs in a curve, the trajectory of said tractor head is offset and the accident occurs, as stated and explained above.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El sistema que se preconiza ha sido concebido para resolver a problemática anteriormente expuesta, en base a una solución sencilla pero 25 eficaz. The system that has been recommended has been conceived to solve the problems described above, based on a simple but effective solution.
En tal sentido, el sistema está previsto para evitar el empuje In this regard, the system is designed to prevent thrust.
adicional del semirremolque sobre la cabeza tractora y evitar con ello el of the semi-trailer on the tractor unit and avoid
accidente. accident.
Mas concretamente, el sistema de la invención se basa en More specifically, the system of the invention is based on
establecer una mayor potencia de frenado del semirremolque respecto del establish a higher braking power of the semi-trailer with respect to the
que ofrece la cabeza tractora, lo que da lugar a que dicho semirremolque, offered by the tractor unit, which results in said semi-trailer,
5 por su frenado mas enérgico que el de la cabeza tractora, sujeta a ésta desde atrás, como si de un ancla se tratara. Es decir, se evita el empuje adicional referido sobre la cabeza tractora para evitar con ello el efecto “tijera”. 5 for its braking more energetic than that of the tractor unit, attached to it from behind, as if it were an anchor. That is, the additional thrust referred to on the tractor head is avoided to thereby avoid the "scissor" effect.
Para ello se ha previsto que asociado al convencional sistema de For this, it is planned that associated with the conventional system of
10 frenado ABS de los vehículos, y en correspondencia con la quinta rueda que conecta mecánicamente el semirremolque con la cabeza tractora, se establezca un sistema de conexión móvil para esa quinta rueda, manteniendo a ésta en su posición natural pero con facultad de un pequeño desplazamiento longitudinal dentro de unas guías establecidas al efecto en el 10 ABS braking of the vehicles, and in correspondence with the fifth wheel that mechanically connects the semi-trailer with the tractor head, a mobile connection system for that fifth wheel is established, keeping it in its natural position but with the power of a small displacement longitudinal within guides established for this purpose in the
15 chasis de la propia cabeza tractora, de manera que respecto de esas guías la quinta rueda queda imposibilitada de desplazamiento lateral. Es decir, la referida quinta rueda, en lugar de ir montada de forma estática o inamovible sobre el chasis de la cabeza tractora como es convencional, irá montada con facultad de desplazamiento longitudinal, lo que permite llevar a efecto una 15 chassis of the tractor itself, so that with respect to these guides the fifth wheel is unable to move sideways. That is to say, the said fifth wheel, instead of being mounted in a static or immovable way on the chassis of the tractor head as is conventional, will be mounted with the power of longitudinal displacement, which allows to carry out a
20 regulación del esfuerzo que soporta en sentido longitudinal, en caso de que el semirremolque transmita de forma excesiva su empuje a la referida cabeza tractora, en aquellas condiciones en que el frenado de ésta supere el esfuerzo de frenado del propio semirremolque. 20 regulation of the stress that it supports in the longitudinal direction, in the event that the semi-trailer transmits its thrust excessively to the said tractor, in those conditions in which the braking of the latter exceeds the braking effort of the semi-trailer itself.
25 A dicho sistema deslizante se le dotará, en su parte delantera, de unos detectores de presión para detectar el empuje ejercido de forma longitudinal, en el momento en que se produzca una excesiva presión de carga sobre la cabeza tractora, transformándose dicha presión en una corriente eléctrica que será tanto mayor cuanto mayor sea la presión 25 Said sliding system will be provided, in its front part, with pressure detectors to detect the thrust exerted longitudinally, at the moment when excessive loading pressure is produced on the tractor head, said pressure being transformed into a electric current that will be much higher the higher the pressure
ejercida longitudinalmente. exercised longitudinally.
La presión referida será medida convenientemente y cuando The referred pressure will be measured conveniently and when
excede de un valor predeterminado, los detectores a través de un exceeds a predetermined value, the detectors through a
programador actuarán sobre el sistema de frenado ABS del propio vehículo, programmer will act on the ABS braking system of the vehicle itself,
5 liberando la presión de frenado sobre la cabeza tractora. 5 releasing the braking pressure on the tractor head.
En tales circunstancias, cuando no se produzca empuje porque el In such circumstances, when no thrust occurs because the
semirremolque frene mas que la cabeza tractora, no se presentará el semitrailer brakes more than the tractor head, the
problema comentado, pero cuando la frenada del semirremolque sea menor problem commented, but when the semitrailer braking is less
10 que la de la cabeza tractora y aquel se abalance sobre dicha cabeza tractora, el montaje deslizante de la quinta rueda lleva consigo un desplazamiento de ésta hacia la parte delantera, apoyando sobre los comentados detectores para que, superado el valor pre-establecido, enviar una señal al sistema de frenado de la cabeza tractora a través del ABS, quedando entonces liberado 10 that that of the tractor unit and that one is balanced on said tractor unit, the sliding assembly of the fifth wheel carries with it a displacement of the latter towards the front, resting on the said detectors so that, exceeding the pre-established value, send a signal to the braking system of the tractor unit through the ABS, then being released
15 durante una centésima de segundo, la necesaria para que se deje de producir dicho empuje, pasando a producirse justamente el efecto contrario, con lo que en el caso de haberse empezado a producir el desalineado de los ejes del semirremolque con la cabeza tractora, ese desalineamiento se anularía y dichos ejes quedarían alineados instantáneamente, de manera que a la 15 for one hundredth of a second, the one necessary to stop producing said thrust, just the opposite effect will occur, so that in the case of having started to misalign the axles of the semi-trailer with the tractor head, that misalignment would be canceled and these axes would be aligned instantly, so that the
20 siguiente centésima de segundo los frenos quedarían de nuevo activados, prosiguiendo con el proceso de frenado del conjunto una vez estabilizada la trayectoria del conjunto cabeza tractora-semirremolque. 20 following one hundredth of a second the brakes would be activated again, continuing with the braking process of the assembly once the trajectory of the tractor-semi-trailer head stabilized.
Por último decir que no solamente se puede conseguir que la Finally say that not only can you get that
25 quinta rueda no solo mida el empuje longitudinal del semirremolque o carga sobre la cabeza tractora, sino que se puede medir incluso el peso que soporta dicho sistema, y en función de ambos introducir los valores en el correspondiente procesador encargado de realizar el cálculo, llevando a cabo la comparación con los valores prefijados. Se puede incluso regular la 25 fifth wheel not only measures the longitudinal thrust of the semi-trailer or load on the tractor head, but it can also measure the weight that supports said system, and depending on both enter the values in the corresponding processor responsible for carrying out the calculation, carrying Carry out the comparison with the default values. You can even regulate the
30 sensibilidad del sistema en función de las diferentes condiciones de la vía o de la carga transportada, es decir del semirremolque, o bien proceder a un desactivado manual para casos necesarios de maniobra de cualquier tipo. 30 system sensitivity depending on the different conditions of the track or the cargo transported, that is, the semi-trailer, or proceed to a manual deactivation for necessary maneuver cases of any kind.

5 REALIZACIÓN PREFERENTE DE LA INVENCIÓN 5 PREFERRED EMBODIMENT OF THE INVENTION
Como se puede comprobar en las figuras referidas, y en concreto As can be seen in the aforementioned figures, and specifically
en la figura 1, se deja ver en primer lugar el efecto tijera que produce el par in figure 1, the scissor effect produced by the pair is shown first
de cierre entre el semirremolque (1) y la cabeza tractora (2) closing between the semi-trailer (1) and the tractor unit (2)
10 correspondientes a un vehículo articulado, todo ello cuando exista un empuje del semirremolque (1) sobre dicha cabeza tractora (2), observándose como las fuerzas (3 y 4) que se ejercen sobre la quinta rueda (5), llevan a cabo el par de cierre comentado, tendiendo a producirse el efecto tijera y en consecuencia el accidente del vehículo, como ocurre convencionalmente. 10 corresponding to an articulated vehicle, all when there is a push of the semi-trailer (1) on said tractor head (2), observing how the forces (3 and 4) exerted on the fifth wheel (5), carry out the commented closing torque, tending to produce the scissor effect and consequently the accident of the vehicle, as conventionally occurs.
15 Ahora bien, en el caso en que el semirremolque (1) frene mas que la cabeza tractora (2), como se representa en la figura 2, entonces el par de fuerzas (3’) y (4’) hacen las veces de ancla tendiendo a alinear los ejes del comentado semirremolque (1) y de la cabeza tractora (2), evitando 15 Now, in the case where the semi-trailer (1) brakes more than the tractor head (2), as shown in Figure 2, then the torque (3 ') and (4') act as anchor tending to align the axles of the commented semi-trailer (1) and the tractor head (2), avoiding
20 por lo tanto el efecto tijera referido para la figura 1. 20 therefore the scissor effect referred to in figure 1.
Por otro lado, como se representa en la figura 2, la quinta rueda On the other hand, as shown in Figure 2, the fifth wheel
