Title
(EN) MODIFIED VEHICLE SUSPENSION
(FR) SUSPENSION MODIFIEE POUR VEHICULE
Abstract
(EN)
A vehicle such as a trailer includes a vehicle body (10), a pair of ground wheels (26) and a suspension system (30) resiliently supporting the body (10) with respect to the wheels (26). The suspension system (30) is so dimensioned and positioned as to be actuable to alter the relative vertical positions of the ground wheels (26) and vehicle body (10) from a normal condition in which the vehicle is mobile to one in which, with a first extremity (24) of the vehicle body (10) supported in a raised position, the vehicle body (10) is inclined from said first extremity (24) to a lowered extremity (25) closely adjacent or in contact with the ground. The preferred suspension includes inflatable/deflatable air bags (38) having air supply lines (40) and acting between the vehicle body (10) and arms (32) which support the wheels (26).
(FR)
Un vehicule tel qu"une remorque comprend un chassis (10), une paire de roues (26) et un systeme de suspension (30) supportant elastiquement le chassis (10) par rapport aux roues (26). Le systeme de suspension (30) est dimensionne et positionne de maniere a pouvoir etre actionne pour modifier les positions verticales relatives des roues au sol (26) et le chassis (10) a partir d"un etat normal ou le vehicule est mobile vers un etat ou, une premiere extremite (24) du chassis (10) etant supportee dans une position relevee, le chassis (10) est incline depuis ladite premiere extremite (24) vers une extremite abaissee (25) proche ou au contact du sol. La suspension preferee comprend des coussins d"air gonflables/degonflables (38) ayant des conduites d"alimentation d"air (40) et agissant entre le chassis (10) et les bras (32) qui supportent les roues (26).
