Title (EN) VEHICLE SUSPENSION SYSTEM
(FR) SYSTEME DE SUSPENSION POUR VEHICULE
Abstract: front page image
(EN)The advent of relatively wide beadless tires on off-highway trucks and the like has dictated the desirability of providing a suspension system which separates the damping functions during the bounce and roll movements occurring between a truck frame and an axle assembly suspended thereunder. In particular, it is desirable to provide a soft suspension during the bounce mode of vehicle operation whereas a relatively stiff suspension is desired during the roll mode thereof. The suspension system (12) of this invention accomplishes the above by providing a first suspension (18) for damping bouncing movements (B) and a separate and isolated second, suspension (24) for damping rolling movements (R), with the second suspension (24) being disposed in a vertical plane which intersects a universal connection (16) connecting an axle assembly (11) to a vehicle frame (10). The second suspension (24) includes a pair of springs (25) which are spaced outboard of the frame (10) to and in stabilizing the vehicle.
(FR)L"utilisation de pneus relativement larges sans talon pour des camions tout terrain et autres vehicules a dicte le besoin de concevoir un systeme de suspension qui separe les fonctions d"amortissement pendant les mouvements de rebond et de roulis se produisant entre le chassis d"un camion et un ensemble d"essieux suspendus sous ce dernier. En particulier, il est desirable d"avoir une suspension douce pendant le rebond du vehicule en fonctionnement et une suspension plutot dure pendant le roulis du vehicule. Le systeme de suspension (12) de cette invention satisfait les conditions susmentionnees grace a une premiere suspension (18) d"amortissement des mouvements de rebond (B) et une seconde suspension separe et isolee (24) pour amortir les mouvements de roulis (R), la seconde suspension (24) etant disposee dans un plan vertical qui intersecte une connexion universelle (16) reliant un ensemble d"essieux (11) au chassis (10) d"un vehicule. La seconde suspension (24) comprend une paire de ressorts (25) qui sont espaces a l"exterieur du chassis (10) pour stabiliser le vehicule.
