Campo de la invenciónField of the invention
La presente invención se refiere a una suspensión mixta mecánica-neumática que proporciona las características y ventajas de poseer los dos tipos de suspensiones al vehículo que tiene la suspensión objeto de la invención. La suspensión mixta mecánicaneumática es de aplicación en la industria de la automoción.The present invention refers to a mixed mechanical-pneumatic suspension that provides the characteristics and advantages of having the two types of suspensions to the vehicle having the suspension object of the invention. The mechanical-pneumatic mixed suspension is used in the automotive industry.
Antecedentes de la invenciónBackground of the invention
Actualmente el diseño de la suspensión de un vehículo se realiza partiendo de una especificación inicial que considera de manera independiente el desarrollo mecánico, hidráulico o neumático.Currently, the design of the suspension of a vehicle is carried out based on an initial specification that independently considers the mechanical, hydraulic or pneumatic development.
En el estado de la técnica actual no se realizan soluciones mixtas en vehículos desde el montaje en fábrica, es decir no se realizan suspensiones consistentes en una suspensión mecánica con apoyo neumático o hidráulico. Si se ejecutan, son en caso de adaptaciones de vehículos comerciales, con desarrollos particulares y específicos para cada caso, ya que, ninguno de los vehículos ha sido diseñado para albergar esa suspensión mixta.In the current state of the art, mixed solutions are not made in vehicles from the factory assembly, that is, suspensions consisting of a mechanical suspension with pneumatic or hydraulic support are not made. If they are executed, they are in the case of adaptations of commercial vehicles, with particular and specific developments for each case, since none of the vehicles has been designed to house this mixed suspension.
El diseño mixto mecánico con apoyo de un sistema neumático o hidráulico tiene una serie de ventajas que se pueden enumerar de la siguiente manera:The mixed mechanical design supported by a pneumatic or hydraulic system has a number of advantages that can be listed as follows:
- posibilidad de cambiar la altura del vehículo independiente de la carga.- possibility of changing the height of the vehicle independent of the load.
- posibilidad de escoger la rigidez del muelle en función de la carga del vehículo y regular la altura de la suspensión con el componente neumático.- possibility of choosing the stiffness of the spring according to the load of the vehicle and regulating the suspension height with the pneumatic component.
- capacidad de funcionar aún fallando el sistema neumático, ya que el peso lo soporta un componente del sistema mecánico, lo que es de vital importancia para vehículos con aplicaciones especiales, como el vehículo objetivo de la suspensión objeto de la invención, donde es importante que el vehículo pueda operar aún en el caso de que falle algún sistema.- Ability to function even if the pneumatic system fails, since the weight is supported by a component of the mechanical system, which is of vital importance for vehicles with special applications, such as the target vehicle of the suspension object of the invention, where it is important that the vehicle can operate even in the event of a system failure.
Además, que un mismo vehículo disponga de las dos opciones de suspensión (mecánica-neumática), es importante sobre todo en vehículos destinados a diferentes aplicaciones y donde la carga sobre el eje del vehículo puede ser diferente en cada aplicación y tiene grandes variaciones de carga entre la situación de vehículo vacío y vehículo cargado.In addition, that the same vehicle has both suspension options (mechanical-pneumatic), it is important especially in vehicles intended for different applications and where the load on the axle of the vehicle may be different in each application and has large load variations between empty vehicle and loaded vehicle situation.
