Device for resiliently supporting a driver's compartment, particularly in heavy-duty trucks

摘要

A device for resiliently supporting a driver's compartment subjected to vibrations in heavy-duty trucks having a non-resilient wheel suspension, said compartment housing at least one seat and being connected to a supporting portion of the vehicle by three or more spring structure, spaced circumferentially around the compartment, the point of connection of said spring structure with the compartment being disposed in a common and substantially horizontal plane located closely adjacent the center of gravity of said compartment. The axis of action of said spring structures forms an acute angle with a vertical axis so as to allow the accomodation of vibrations in all directions in a three-axis right-angle coordinate system, i.e. to obtain all six degrees of freedom of movement.
