Description
Suspensión mecánica, para maquinaria agrícola.Mechanical suspension, for machinery agricultural.
El objeto del invento es una suspensión mecánica, para maquinaria agrícola y, más en concreto, una suspensión mecánica para tractores, que emplea contrapesos de inercia.The object of the invention is a suspension mechanical, for agricultural machinery and, more specifically, a mechanical suspension for tractors, which uses counterweights of inertia.
Convencionalmente, la maquinaria agrícola se dispone en bastidores y es cautiva de un tractor del que depende para que pueda funcionar (pues necesita siempre un elemento motriz). La Patente WO92/ 09190, por ejemplo, se refiere a maquinaria agrícola de este tipo.Conventionally, agricultural machinery is It has racks and is captive of a tractor on which it depends so that it can work (it always needs an element motor) WO92 / 09190, for example, refers to Agricultural machinery of this type.
Cuando se transporta la maquinaria agrícola, su
balanceo es perjudicial para el tractor. Consecuentemente hay que
reducirlo y, a ser posible, elimi-
narlo.When agricultural machinery is transported, its balancing is detrimental to the tractor. Consequently, it must be reduced and, if possible, eliminated
tell him
Una forma de eliminarlo consiste en disponer contrapesos con suspensión.One way to eliminate it is to have counterweights with suspension.
Ya se conocen diversas formas de disponer los contrapesos (incluso de variar el peso de dichos contrapesos para adecuarlos a terrenos o conducciones de trabajo diferentes).Various ways of arranging the Counterweights (including varying the weight of such counterweights to adapt them to different terrains or work ducts).
También se conocen suspensiones, pero las suspensiones conocidas por el solicitante resultan excesivamente complejas (y, por tanto de dificultoso y complicado mantenimiento, reparación o sustitución en caso de avería o deterioro) pues basan su funcionamiento en la actuación fluídica lo cual, además, requiere una conexión previa al sistema hidráulico del propio tractor.Suspensions are also known, but the suspensions known to the applicant result excessively complex (and therefore difficult and complicated maintenance, repair or replacement in case of breakdown or deterioration) as they base its functioning in fluidic performance which, in addition, requires a previous connection to the hydraulic system itself tractor.
El solicitante ha desarrollado una suspensión de funcionamiento totalmente mecánico y que funciona siempre totalmente independientemente del propio tractor. Se caracteriza porque consta de:The applicant has developed a suspension of fully mechanical operation and always fully functioning regardless of the tractor itself. It is characterized because it consists from:
a) un bastidor flotante, estructurado en dos semi-partes, unidas articuladamente entre sí mediante articulación fija y que, respectivamente, se montan en el bastidor de la maquinaria agrícola y montan en sí mismas al contrapeso que proporciona estabilidad a dicha maquinaria agrícola;a) a floating frame, structured in two semi-parts, articulated together by fixed articulation and that, respectively, are mounted on the frame of agricultural machinery and assemble themselves to counterweight that provides stability to said machinery agricultural;
b) al menos un dispositivo amortiguador mecánico unido articuladamente a las semi-partes del bastidor flotante mediante respectivas articulaciones fijas; de modo que, con la maquinaria agrícola en movimiento, los contrapesos contrarrestan las irregularidades del terreno, sin transmitirlas al tractor;b) at least one mechanical damping device articulated jointly to the semi-parts of the floating frame by means of respective fixed joints; from so that, with the agricultural machinery in motion, the counterweights counteract the irregularities of the land, without transmitting them to the tractor;
c) medios para regular la rigidez de dicho dispositivo amortiguador mecánico; de modo que una misma suspensión puede adaptarse a diferentes condiciones de trabajo o a maquinaria agrícola de diferentes potencias.c) means to regulate the stiffness of said mechanical damping device; so that the same suspension can adapt to different working conditions or machinery Agricultural of different powers.

Se describe a continuación un ejemplo de realización práctica, no limitativa, del presente invento.An example of practical, non-limiting embodiment of the present invention.
La presente invención trata de una suspensión mecánica, para maquinaria agrícola que consta, básicamente, de:The present invention concerns a suspension mechanical, for agricultural machinery consisting basically of:
a) un bastidor flotante (1),a) a floating frame (1),
b) al menos, un dispositivo amortiguador mecánico (2), yb) at least one damping device mechanical (2), and
c) medios (3) para regular la rigidez de dicho dispositivo amortiguador mecánico (2).c) means (3) for regulating the stiffness of said mechanical damping device (2).
El bastidor flotante (1) va montado en el bastidor (B) de la maquinaria agrícola y admite en sí mismo a uno o varios contrapesos (C), que pueden disponerse y retirarse con facilidad, a voluntad y de acuerdo con las necesidades concretas del usuario en cada momento.The floating frame (1) is mounted on the frame (B) of agricultural machinery and admits itself to one or several counterweights (C), which can be arranged and removed with ease, at will and according to specific needs of the user at all times.
De conformidad con la invención, y según la realización representada, el bastidor flotante (1) se estructura en dos semi-partes (1a), (1b) unidas articuladamente entre sí mediante una articulación fija (11). Una de las semi-partes (1a) es la que se monta en el bastidor (B) de la maquinaria agrícola y la otra semi-parte (1b) es la que soporta los contrapesos (C) -ver figura 1-.In accordance with the invention, and according to the represented embodiment, the floating frame (1) is structured in two semi-parts (1a), (1b) articulated together each other through a fixed joint (11). One of the semi-parts (1a) is the one that is mounted on the frame (B) of agricultural machinery and the other semi-part (1b) is the one that supports the counterweights (C) -see figure 1-.
Estas dos semi-partes (1a), (1b) del bastidor (1) van también relacionadas entre si por, al menos, un dispositivo amortiguador mecánico (2) -además de por la articulación fija (11) antes citada-. Esta relación es también mediante articulaciones fijas (2a), (2b).These two semi-parts (1a), (1b) of the frame (1) are also related to each other by at least a mechanical damping device (2) - in addition to the fixed joint (11) mentioned above.

La posición relativa del juego de
tuerca/contra-
tuerca (32) respecto a la articulación más
próxima (2b) -distancia (d)- determina la rigidez del dispositivo
amortiguador mecánico (2): a distancia (d) más grande, mayor
rigidez.The relative position of the nut / counter kit
nut (32) with respect to the nearest joint (2b) -distance (d) - determines the stiffness of the mechanical damping device (2): larger distance (d), greater rigidity.
En este ejemplo de realización representado los propios medios (3) constituyen uno de los topes extremos (23b) si bien tope extremo (23b) y medios (3) pueden ser independientes entre sí -empleando, por ejemplo como tope (23b) un amortiguador elástico similar al (23a) del otro lado, intercalado entre los medios de regulación (3) y el resorte-amortiguador (22)-.In this exemplary embodiment represented the own means (3) constitute one of the extreme stops (23b) if either end stop (23b) and means (3) can be independent each other - using, for example as a stop (23b) a shock absorber elastic similar to (23a) on the other side, sandwiched between the regulating means (3) and spring-damper (22) -.
