Suspension device, for the suspension of a cabin in particular, on the chassis of a vehicle
First Claim
1. A three point suspension device for suspending a cabin on a vehicle chassis comprising a first elastic connection assembly interposed between said chassis and said cabin at a central position adjacent the front portions of said chassis and cabin, said elastic connection assembly having a resonant frequency in the range of from about 1 to about 3 Hz, second and third connections interposed between said cabin and chassis, said second and third connections being disposed at a position rearwardly spaced from said first connection and being laterally spaced symmetrically to opposite sides of the longitudinal rolling axis of said cabin, and an anti-roll torsion bar assembly interposed between said chassis and cabin and positioned to restrain relative rotation of said cabin with respect to said chassis about said rolling axis.

Abstract
Suspension device, for the suspension of a cabin on a vehicle chassis.
The undertray of the cabin is suspended in at least three points on the chassis of which at least one point at the front and two points at the rear, the middle front point of the cabin suspended by an elastic element of low frequency being connected to the chassis by a means for guiding the undertray of the cabin and said cabin being connected to the chassis by an elastic return means for controlling the roll of the cabin.
The invention finds an application for the suspension of truck cabins.
