Title: Sistema estructural de chasis accionado por la gravedad que impide la inclinación del vehículo
Inventor: LIZARI ILLARRAMENDI IÑIGO
IPC: B62D37/04
Filed: 2015-01-02
Granted: 2015-11-12
Abstract: Sistema estructural de chasis que por acción de la gravedad impide la inclinación del vehículo, caracterizado por disponer de un chasis dual modular que comprende un chasis primario externo colgador exoesquelético de geometría variable que descansa sobre los elementos rodantes del vehículo y otro chasis secundario interno colgante endoesquelético rígido. Ambos chasis se unen en articulación desde el centro de su respectiva parte superior y se abrazan en sus respectivos laterales sin fijarse a través de una guías, lo cual imposibilita el desplazamiento del centro de la gravedad del cuerpo del vehículo fuera del centro de la base del chasis interno en donde se deposita la carga y sobre la que se asienta el habitáculo, aun cuando el terreno supere los 45º de inclinación, y supone una restructuración mecánica total de la arquitectura constructiva de los vehículos con elementos rodantes laterales paralelos al chasis que tiene múltiples aplicaciones.
