Description
Mecanismo combinado de dirección y suspensión para vehículos.Combined steering and suspension mechanism for vehicles.
La presente invención se refiere a un mecanismo combinado de dirección y suspensión que se emplea en las ruedas directrices de un vehículo, de especial aplicación para vehículos todo terreno.The present invention relates to a mechanism combined steering and suspension used on wheels vehicle guidelines, especially for vehicles all terrain.
Es objeto de la invención que los elementos que conforman el sistema de dirección queden situados en un plano superior al de las ruedas para evitar su deterioro por los impactos que puedan producirse contra posibles obstáculos durante la circulación del vehículo sobre terrenos irregulares, proporcionando además una mayor altura libre entre el chasis y el terreno.It is the object of the invention that the elements that make up the steering system are located in a plane higher than the wheels to avoid deterioration due to impacts that may occur against possible obstacles during the vehicle circulation on uneven terrain, providing also a greater free height between the chassis and the ground.
Otro objetivo de la invención consiste en facilitar un mayor recorrido de las ruedas del vehículo de forma totalmente independiente cuando el vehículo circula por terrenos irregulares.Another object of the invention is to facilitate greater vehicle wheel travel so fully independent when the vehicle is driving on land irregular.
Es asimismo objeto de la invención disponer los medios para que la suspensión, a parte de su propio cometido, se constituya en el medio de transmisión del movimiento ocasionado por el sistema de dirección hacia las ruedas.It is also the object of the invention to provide the means for the suspension, apart from its own purpose, to be it constitutes the means of transmission of the movement caused by the steering system towards the wheels.
Actualmente existen en el mercado diferentes tipos de vehículos que disponen de forma generalizada un chasis, dos ruedas directrices y al menos de dos ruedas motrices, además de otros elementos de uso generalizado que no guardan relación directa con el objeto de la presente invención.Currently there are different in the market types of vehicles that generally have a chassis, two steering wheels and at least two driving wheels, in addition to other elements of generalized use that are not directly related for the purpose of the present invention.
Habitualmente en este tipo de vehículos la columna de dirección se extiende hasta un plano inferior, situado entre las ruedas directrices, realizándose la transmisión del movimiento desde la columna de dirección hasta dichas ruedas directrices en el mencionado plano inferior.Usually in these types of vehicles the steering column extends to a lower plane, located between the steering wheels, the transmission of the movement from the steering column to said wheels guidelines in the mentioned lower plane.
La ubicación de determinados elementos de la dirección, como la cremallera o las barras laterales en el plano inferior, es decir, entre las ruedas directrices, limita considerablemente la altura libre por debajo del chasis, así como el formato y anclaje de los brazos de suspensión y consiguientemente la capacidad del vehículo para salvar obstáculos.The location of certain elements of the direction, such as the zipper or the side bars in the plane lower, that is, between the steering wheels, limits considerably the free height below the chassis, as well as the format and anchoring of the suspension arms and consequently the ability of the vehicle to overcome obstacles.
De otra parte, es habitual que las ruedas se encuentren montadas sobre el chasis por medio de unos brazos o trapecios que giran sobre sendos ejes sensiblemente longitudinales respecto al vehículo, lo que limita considerablemente el recorrido de las ruedas en dirección vertical y consiguientemente la capacidad de las ruedas para disponerse a diferentes niveles al circular el vehículo sobre terrenos con irregularidades importantes.On the other hand, it is common for the wheels to be are mounted on the chassis by means of arms or trapezoids that rotate on both substantially longitudinal axes regarding the vehicle, which considerably limits the route of the wheels in vertical direction and consequently the capacity of the wheels to be arranged at different levels when the vehicle on land with significant irregularities.
Por otro lado al encontrarse los elementos conformantes de la dirección en un plano inferior, estos pueden deteriorarse por impactos contra posibles obstáculos durante la circulación del vehículo sobre terrenos irregulares.On the other hand when the elements meet address shapers in a lower plane, these can deteriorate from impacts against possible obstacles during Vehicle circulation on uneven terrain.
El mecanismo combinado de dirección y suspensión para vehículos objeto de esta invención viene a resolver la problemática anteriormente expuesta, mediante la incorporación de los elementos de la dirección en un plano superior al de las ruedas sobre las que actúan indirectamente por intermediación de la suspensión, que ha sido convenientemente adaptada para recibir el movimiento de la dirección y transmitirlo hacia las ruedas, al mismo tiempo que mantiene su función como elemento de absorción de irregularidades del terreno.The combined steering and suspension mechanism for vehicles object of this invention comes to solve the problematic exposed previously, by means of the incorporation of the steering elements in a plane higher than the wheels on those that act indirectly through the intermediation of the suspension, which has been conveniently adapted to receive the steering movement and transmit it to the wheels at the same time that maintains its function as an element of absorption of terrain irregularities.
La posición de los elementos de la dirección a nivel superior reduce las posibilidades de que estos se vean afectados por impactos de piedras u otros objetos durante la circulación del vehículo, en especial sobre terrenos irregulares, así como proporciona una mayor altura libre entre el chasis y el terreno y la posibilidad de que las ruedas tengan mayor recorrido durante su desplazamiento vertical.The position of the management elements a higher level reduces the chances that these will look affected by impacts of stones or other objects during the vehicle circulation, especially on uneven terrain, as well as providing a greater free height between the chassis and the terrain and the possibility that the wheels have longer travel during its vertical displacement.
Así pues los elementos de la dirección encargados de transmitir el movimiento del volante a los laterales opuestos del vehículo se encuentran situados en un plano superior, sensiblemente por encima de las ruedas del vehículo y conectados por medio de sendas manetas de accionamiento al extremo superior de los amortiguadores correspondientes a las ruedas directrices, siendo dichos amortiguadores los encargados de transmitir el movimiento de giro desde el plano superior hasta el soporte orientable de la rueda directriz correspondiente.So the management elements in charge of transmitting the movement of the steering wheel to the opposite sides of the vehicle are located in a higher plane, noticeably above the wheels of the vehicle and connected by means of two drive handles to the upper end of the shock absorbers corresponding to the steering wheels, being said dampers are responsible for transmitting the movement of rotation from the upper plane to the adjustable wheel support corresponding guideline.
La disposición de los elementos de la dirección, tales como cremallera y brazos laterales, en el plano superior, impide que estos elementos puedan ser golpeados por los diferentes obstáculos salvados por el vehículo, transmitiéndose el movimiento de la dirección a las ruedas por medio de los amortiguadores correspondientes a los respectivos soportes de las ruedas directrices.The arrangement of the management elements, such as zipper and side arms, in the upper plane, prevents these elements from being hit by the different obstacles saved by the vehicle, the movement being transmitted from steering to wheels by means of shock absorbers corresponding to the respective wheel supports guidelines
Los amortiguadores de las ruedas directrices comprenden un émbolo superior fijado por su extremo superior al chasis del vehículo, sobre el que se encuentra montada con posibilidad de desplazamiento longitudinal una camisa inferior vinculada al soporte orientable de la correspondiente rueda directriz, alojándose en el interior de los amortiguadores un resorte o un fluido amortiguador, estando provisto el émbolo superior y la camisa inferior de unos medios de guiado longitudinal que impiden el giro relativo entre el émbolo superior y la camisa inferior, asegurando dichos medios que el movimiento comunicado por la dirección al extremo superior del amortiguador se transmita íntegramente al extremo inferior del mismo y consiguientemente al soporte de la rueda correspondiente.Steering wheel dampers they comprise an upper piston fixed at its upper end to the vehicle chassis, on which it is mounted with possibility of longitudinal displacement a lower jacket linked to the adjustable support of the corresponding wheel guideline, housed inside the shock absorbers a spring or a damping fluid, the piston being provided upper and lower jacket of longitudinal guiding means which prevent the relative rotation between the upper plunger and the sleeve lower, ensuring said means that the movement communicated by the address to the upper end of the shock absorber is transmitted entirely to the lower end thereof and consequently to the corresponding wheel support.
La camisa inferior de los amortiguadores correspondientes a las ruedas directrices disponen de una aleta lateral que se encuentra fijada al soporte orientable de la rueda correspondiente para transmitirle el movimiento de dirección u orientación.The bottom shirt of the shock absorbers corresponding to the steering wheels have a fin side that is fixed to the adjustable wheel support corresponding to transmit the direction movement u orientation.
Esta disposición de elementos permite que los amortiguadores actúen como tales y además, en el caso de las ruedas directrices, que sean los encargados de transmitir el movimiento de la dirección hasta las ruedas.This arrangement of elements allows the shock absorbers act as such and also, in the case of wheels guidelines, which are responsible for transmitting the movement of the direction to the wheels.
Otra de las particularidades de la invención consiste en que cada uno de los soportes de las ruedas se encuentra montado sobre uno de los extremos de un brazo basculante de soporte que se encuentra orientado en dirección sensiblemente longitudinal respecto al vehículo.Another of the particularities of the invention is that each of the wheel stands is mounted on one of the ends of a support swing arm which is oriented in substantially longitudinal direction Regarding the vehicle.
El extremo opuesto de cada uno de los brazos basculantes se encuentra montado con posibilidad de basculamiento o abatimiento limitado e independiente sobre una barra transversal del chasis. Esta característica permite por un lado que las ruedas puedan situarse de forma independiente a diferentes niveles y por otro lado que el recorrido de las mismas en dirección vertical sea mayor al de otros sistemas existentes en el mercado.The opposite end of each of the arms swingarms is mounted with the possibility of tilting or limited and independent abatement on a crossbar of the chassis. This feature allows on the one hand that the wheels can be placed independently at different levels and by other side that the route of the same in vertical direction is greater than other systems in the market.
Para posibilitar el cambio de orientación de las ruedas directrices se ha previsto que los soportes de las ruedas directrices se encuentren montados sobre los respectivos brazos basculantes con posibilidad de giro sobre un eje sensiblemente vertical.To enable the change of orientation of the Steering wheels are expected to be wheel supports guidelines are mounted on the respective arms swingarms with the possibility of turning on an axis substantially vertical.
De acuerdo con la invención las barras transversales del chasis presentan una sección sensiblemente rectangular, encontrándose montados los soportes basculantes sobre las correspondientes barras transversales por medio de sendos elementos tubulares, de sección sensiblemente rectangular, montados coaxial y exteriormente respecto a la correspondiente barra transversal del chasis.According to the invention the bars chassis cross sections have a substantially section rectangular, with the swinging supports mounted on the corresponding crossbars by means of two tubular elements, of substantially rectangular section, mounted coaxially and externally with respect to the corresponding bar chassis cross.
Los elementos tubulares, solidarios a los respectivos brazos basculantes, se encuentran desfasados angularmente respecto a las barras transversales del chasis, quedando definidos entre los elementos tubulares y la correspondiente barra transversal unos huecos de configuración sensiblemente prismática triangular en los que se alojan unas piezas de material elástico que tienden a mantener los brazos basculantes en una determinada posición angular de basculación y que se deforman elásticamente cuando se varía la posición angular de dichos brazos, es decir se varía la altura de las ruedas debido a las irregularidades del terreno.Tubular elements, integral to the respective swingarms, are out of date angularly with respect to the crossbars of the chassis, being defined between the tubular elements and the corresponding crossbar configuration holes noticeably triangular prismatic in which some pieces are housed made of elastic material that tend to keep the swingarms in a certain angular tilting position and they deform elastically when the angular position of said arms is varied, that is, the height of the wheels is varied due to the terrain irregularities.
