Description

Sistema de amortiguación y disminución de vibraciones para vehículos de propulsión por cadenas.Damping system and decrease of vibrations for chain propulsion vehicles.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un sistema de amortiguación-reductor de vibraciones entre los eslabones de cadena y los dientes de las ruedas de los vehículos de propulsión por cadenas.The present invention relates to a system of  vibration damping-reducer between chain links and wheel teeth of vehicles  chain drive.

Antecedentes de la invenciónBackground of the invention

En los vehículos de propulsión por cadenas, en general, y preferentemente los carros de combate, por ejemplo, el español "Pizarro" se detecta que a velocidades de 10-20-60 Kilómetros/hora se producen fuertes vibraciones ocasionadas fundamentalmente por el contacto en la rodadura entre los eslabones de las cadenas y los dientes de la ruedas.In chain drive vehicles, in general, and preferably battle tanks, for example, the Spanish "Pizarro" is detected that at speeds of 10-20-60 kilometers / hour occur strong vibrations caused primarily by contact in the rolling between the links of the chains and the teeth of the wheels.

Este efecto en mayor o menor medida se produce en todos los carros de combate y vehículos de accionamiento por cadena, debido a los golpeteos por los errores de enganche entre el eslabón de la cadena y el diente de las ruedas propulsoras, cuyo grado de acoplamiento es relativamente imperfecto, comparado con sistemas de accionamiento por juntas homocinéticas, cardan y neumáticos, que presentan un funcionamiento mucho más suave, silencioso y ausente de vibraciones.This effect to a greater or lesser extent occurs in all tanks and vehicles driven by chain, due to the tapping due to the errors of coupling between the chain link and the drive wheel tooth, whose degree of coupling is relatively imperfect, compared to drive systems for homokinetic joints, cardan and tires, which have a much smoother operation, Silent and absent from vibrations.

La solución de este problema pasa en primer lugar por amortiguar los golpeteos mencionados con resultados de disminución en las vibraciones en todas las condiciones de funcionamiento del carro, esta solución se da en la presente invención y concretamente con el sistema objeto de la misma que es el de amortiguar y reducir dichas vibraciones.The solution of this problem happens first place for cushioning the mentioned tapping with results of decrease in vibrations in all conditions of car operation, this solution is given here invention and specifically with the system object of it which is that of damping and reducing these vibrations.

La problemática se presenta, tras hacer trabajar a los carros de combate en las condiciones más adversas que provocan fuertes tensiones en la ruedas, entre los eslabones de las cadenas y los dientes de la ruedas. Como consecuencia se producen los golpeteos y aumento de las vibraciones que se transmiten a todo el vehículo, acelerando el desgaste de la cadena pudiendo llegar a la rotura por desgaste prematuro de la cadena, acortando la vida de la misma.The problem arises, after doing work to tanks under the most adverse conditions that cause strong tension in the wheels, between the links of the chains and wheel teeth. As a result they occur the knocking and increased vibrations that are transmitted to everything the vehicle, accelerating chain wear and can reach breakage due to premature chain wear, shortening life Of the same.

También se producen alteraciones físicas en los usuarios y/o tripulación con síntomas de alteraciones nerviosas, agotamiento, náuseas, e incluso llegando al vómito.Physical alterations also occur in the users and / or crew with symptoms of nervous disorders, exhaustion, nausea, and even vomiting.

El sistema de amortiguación-reducción de vibraciones objeto de la invención disminuye el contacto entre el eslabón de la cadena y el diente de la rueda, restringiendo el juego en sentido axial.System vibration damping-reduction subject to invention decreases the contact between the chain link and the wheel tooth, restricting play axially.

Este sistema consiste básicamente en incorporar un elemento amortiguador entre cadena y el diente, que absorba los esfuerzos radiales, no permitiendo que los eslabones de la cadena recorran el fondo del diente. De esta manera los desplazamientos por esta zona se realizarán por elementos amortiguadores y no por el fondo del diente.This system basically consists of incorporating a damping element between the chain and the tooth, which absorbs the radial efforts, not allowing chain links They run along the bottom of the tooth. This way the displacements in this area they will be made by damping elements and not by the bottom of the tooth.

Bajo el punto de vista del montaje, no se contemplan actuaciones a realizar en el vehículo y tan sólo se trata de incorporar unos sectores semicirculares en la zona interior de los eslabones de la cadena, atornillados a la carcasa de la rueda. Estos sectores son los que forman el sistema de amortiguación-reductor de vibraciones propiamente dicho.From the point of view of assembly, I don't know contemplate actions to be carried out in the vehicle and only try to incorporate semicircular sectors in the area inside the chain links, bolted to the housing of the wheel. These sectors are what form the system of vibration damping itself saying.

Descripción de la invenciónDescription of the invention

El sistema de la invención se aplica a carros de combate y vehículos de transmisión por cadena, sin que éstas pasen por modificar partes básicas internas.The system of the invention is applied to cars of  combat and chain transmission vehicles, without them passing for modifying internal basic parts.

Decoro con la invención el sistema comprende utilizar dos sectores semicirculares compuestos de dos tipos material, acero y caucho recauchutado con la dureza adecuada al esfuerzo a transmitir.Decoro with the invention the system comprises use two semicircular sectors composed of two types material, steel and retreaded rubber with adequate hardness to effort to transmit

Estos sectores se amarran con los tornillos de cada corona dentada en la zona interior de cada corona, de forma que los sectores abarquen todo el perímetro de dichas coronas.These sectors are tied with the screws of each toothed crown in the inner zone of each crown, so that the sectors cover the entire perimeter of these crowns.

Este sistema se incorpora en ambas cadenas, derecha e izquierda, y únicamente en la rueda motriz.This system is incorporated in both chains, right and left, and only on the driving wheel.

Los dos sectores tienen la misión de impedir el desplazamiento de los eslabones de la cadena hacia el fondo del diente de la corona dentada, de forma, que no se produzca contacto metálico. De esta forma al realizarse el contacto radial del eslabón y los sectores provistos de la banda de caucho, en ellos se producen la rotura de las vibraciones que evitará su propagación al interior del vehículo.The two sectors have the mission of preventing displacement of the chain links towards the bottom of the tooth of the toothed crown, so that no contact occurs metal. In this way, when the radial contact of the link and sectors provided with the rubber band, they are produce the breakage of vibrations that will prevent its spread to  vehicle interior
