(EN) HYDROFORMED SPACE FRAME AND REARWARD RING ASSEMBLY THEREFORE
(FR) CHASSIS TUBULAIRE HYDROFORME ET ENSEMBLE ANNEAU ARRIERE DUDIT CHASSIS
Abstract
(EN)
A space frame for a motor vehicle having a pair of laterally spaced, longtitudinally extending side rail structures (12), a pair of forward-most upright structures (16) each being connected to a respective side rail structure, thereby forming a pair of A pillars, a pair of roof rail structures (18) , a forward end of each roof rail structure (18) being connected to an upper end of an associated A pillar, and a rearward ring assembly (20) connected at upper portions thereof with the roof rail structures (18) and at bottom portions thereof with the side rail structures (12). The rearward ring assembly (20) having (a) a tubular hydroformed inverted U-shaped upper member (22) having a cross portion, (b) and a pair of leg portions extending downwardly from opposite ends of the cross portion, (b) a pair of tubular hydroformed side members, and (c) a cross structure rigidly connected in ring- forming relation between the second ends of the side members.
