Abstract

Perfeccionamientos en amortiguadores para vehículos con suspensión elástica, que comprenden dos elementos asociados entre sí de un modo deformable en el sentido de la deformación de la suspensión del vehículo, estando previstos los dos elementos del amortiguador para unirse respectivamente a una parte suspendida y a otra no suspendida del vehículo, caracterizados porque comprenden medios de compensación que impiden la deformación relativa de los dos elementos cuando la velocidad de desplazamiento relativa entre las partes del vehículo es inferior a una velocidad límite predeterminada, medios de bloqueo que neutralizan los medios de comprensión cuando la velocidad de desplazamiento es superior a la velocidad límite, y medios de solicitación que aseguran en posición de reposo el mantenimiento de los dos elementos del amortiguador en una posición relativa predeterminada.
